What NHTSA owner complaints mean

These figures count complaints that vehicle owners and other members of the public have submitted to NHTSA's Office of Defects Investigation. NHTSA uses complaints, together with other data, to spot safety issues that may warrant an investigation and to check whether existing recalls go far enough.

They are reports, not findings. Each complaint is the submitter's own account. Its presence in the database does not mean NHTSA has confirmed a defect.
Counts are not defect rates. The data doesn't say how many vehicles were sold, so a raw count can't tell you what share of vehicles had a problem.
Popular models collect more complaints. A model sold in large numbers will usually gather more complaints than a rare one, simply because more people own it.
One complaint can name several components. Totals by component can therefore add up to more than the number of complaints.
Coverage starts in 1995. NHTSA's complaint file contains complaints received since January 1, 1995.

Use complaint patterns as a prompt for questions: whether a recall covers the issue, whether the vehicle you are considering has had the fix, and what a mechanic finds on inspection. For confirmed safety defects, see the recall list for this model.

Model year 2021
General Motors LLC (GM) is recalling certain 2020 Buick Encore GX and 2021 Chevrolet Trailblazer vehicles. The rear attachment bolts of one or both front seats may not have been installed.

Equipment › Other › Labels; Tires
Model year 2021
General Motors LLC (GM) is recalling certain 2021 Chevrolet Trailblazer vehicles factory-equipped with optional 17-inch sport terrain tires. The certification label on these vehicles does not provide the tire size and cold tire pressure information for front and rear tires, as required. As such, these vehicles fail to comply with Federal Motor Vehicle Safety Standard Number 110, "Tire Selection and Rims."
Consequence:
If drivers are uninformed and overinflate or underinflate their tires, this may increase the risk of a crash.
Remedy:
GM will notify owners, and will mail corrected labels for customers to apply, free of charge. The recall began July 1, 2020. Owners may call Chevrolet customer service at 1-800-222-1020. GM's number for this recall is A202304070.

Visibility › Power Window Devices and Controls
Model years 2006–2007
General Motors LLC (GM) is recalling certain model year 2006-2007 Buick Rainier, Chevrolet Trailblazer and GMC Envoy vehicles, and 2006 GMC Envoy XL and Chevrolet Trailblazer EXT vehicles. Fluid may enter into the driver's door master power window switch module, causing corrosion that could result in a short in the circuit board, causing window switches to become inoperative. Previously, the affected vehicles may have had their master power window switch module treated with a protective coating, instead of having it replaced.
Consequence:
The protective coating may not eliminate the risk that the circuit board could short and result in a fire, even while the vehicle is unattended.
Remedy:
GM will notify owners, and dealers will install a new driver's door switch module, free of charge. The recall began on November 2, 2015. Owners may contact Buick customer service at 1-800-521-7300, Chevrolet customer service at 1-800-222-1020, and GMC customer service at 1-800-462-8782. GM's number for this recall is 15700.

Model years 2006–2007
General Motors LLC (GM) is recalling certain model year 2007 Pontiac Grand Prix, 2006-2009 Buick LaCrosse, 2006-2007 Buick Rainier, Chevrolet Trailblazer, GMC Envoy, 2006 Chevrolet Trailblazer EXT, GMC Envoy XL, 2006-2008 Isuzu Ascender, and Saab 9-7x vehicles. In the affected vehicles, the headlamp driver module (HDM) may overheat and fail, causing the headlamps and daytime running lights to not illuminate.
Consequence:
Headlamps that do not illuminate reduce the driver's ability to see the roadway and reduce the vehicle's visibility to oncoming vehicles, both of which increase the risk of a vehicle crash.
Remedy:
GM will notify owners, and dealers will replace the HDM, free of charge. The recall began on May 17, 2016. Owners may contact Buick customer service at 1-800-521-7300 or Pontiac customer service at 1-800-762-2737. GM's number for this recall is 14291.

Fluid may enter the driver's door master power window switch module, causing corrosion that could result in a short in the circuit board. A short may cause the power door lock and power window switches to function intermittently or become inoperative.

Reported Oct 31, 2006
Air Bags › Frontal
Model years 2005–2006
Certain vehicles originally built with cloth seats that were equipped with an automatic air bag passenger sensing system and later reupholstered with aftermarket leather seat cover kits are involved. Testing has indicated that the aftermarket leather seat covers can cause the passenger sensing system to malfunction.
Consequence:
If the passenger sensing system malfunctions, the front air bag on the passenger side may be disabled when it should be enabled, or enabled when it should be disabled. In either case, in the event of a crash that requires air bag deployment, a front passenger's level of injury may be increased.
Remedy:
Because a replacement leather seat cover that is compatible with the passenger sensing system is not available, General Motors (GM) will repurchase these vehicles in accordance with the terms stated in GM's letter to owners. The recall began on November 6, 2006. Owners should contact GM at 1-877-477-1022 to begin the process of repurchasing their vehicle.

Equipment › Other › Labels
Model year 2006
Certain trucks and sport utility vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard No. 110, "tire selection and rims." These vehicles were shipped with tire and loading information labels listing an inacccurate vehicle capacity weight.
Consequence:
A misprinted label could lead to improper vehicle loading specifications or tire inflation which could result in a tire failure, increasing the risk of a crash.
Remedy:
Owners will be provided with corrected labels and installation instructions. At the customer's option, a dealer can install the label for them. The recall began on March 31, 2006. Owners may contact Buick at 1-866-608-8080, Cadillac at 1-866-982-2339, Chevrolet at 1-800-630-2438, GMC at 1-866-996-9463, Hummer at 1-800-732-5493, Pontiac at 1-800-620-7668, Saturn at 1-800-972-8876, or Isuzu at 1-800-255-6727.

Steering › Hydraulic Power Assist › Hose, Piping, and Connections
Model year 2006
Certain passenger vehicles may have been built with a power steering hose that is not to specification. Under extreme steering maneuvers, such as turning the steering wheel fully to the left or right while braking, the hose may fracture and leak fluid.
Consequence:
If this were to occur, power steering assist would be lost and increased steering effort would be required. On vehicles equipped with hydro-boost power brakes, it could also result in loss of power brake assist and increased braking effort would be required. If the power steering fluid spray were to spray onto hot engine parts, an engine compartment fire could occur.
Remedy:
Dealers will inspect the power steering hose(s) for two suspect date codes and replace them if required. The recall will begin on October 14, 2005. Owners may contact Chevrolet at 1-800-630-2438, GMC at 1-866-996-9463, Buick at 1-866-608-8080, Cadillac at 1-866-982-2339, Isuzu at 1-800-255-6727, or Hummer at 1-800-732-5493.

Exterior Lighting › Turn Signal
Model years 2003–2004
On certain trucks and sport utility vehicles, the driver wishing to signal a turn by moving the directional signal lever, (up or down) may cause the front marker/turn lights and rear turn lights to flash in a manner similar to hazard warning, rather than flashing on the desired side only.
Consequence:
The driver may not be able to clearly signal their intentions to turn, change travel lanes, or potentially warn others of an impaired vehicle operating condition increasing the risk of a crash.
Remedy:
Dealers will replace the suspect flasher modules with a new flasher module designed with sealed relays and more durable contact material inside of the relays free of charge. The recall began on August 4, 2005. Isuzu began mailing owner letters on August 4, 2005. Owners may contact Chevrolet at 1-800-630-2438, GMC at 1-866-996-9463, Isuzu at 1-800-255-6727, Buick at 1-866-608-8080, and oldsmobile at 1-800-630-6537.

Visibility › Windshield
Model year 2005
Certain sport utility vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard No. 212, 'windshield mounting.' The windshield urethane bead may not have adhered to the body in certain areas during the cure process.
Consequence:
If a crash occurs, the windshield may not be retained, increasing the risk of injury to a vehicle occupant.
Remedy:
Dealers will replace the windshield free of charge. The recall began on March 10, 2005. Owners may contact Buick at 1-866-608-8080, Chevrolet at 1-800-630-2438, or GMC at 1-866-996-9463.

Exterior Lighting › Brake Lights
Model years 2002–2004
On certain sport utility vehicles, vibration and heat may cause the tail lamp/stop lamp bulb to loosen in its socket. If this occurs, the bulb may flicker and eventually become inoperative.
Consequence:
An inoperative brake lamp will not convey the driver's intention of stopping to drivers in following vehicles, and an inoperative rear turn signal lamp will not convey the driver's intention to turn to drivers in following vehicles. Both of these failures can increase the risk of a crash.
Remedy:
Dealers will inspect the tail lamp/stop lamp assemblies, and if necessary, replace them. The recall began on November 22, 2004. Owners should contact Chevrolet at 1-800-630-2438, oldsmobile at 1-800-630-6537, Buick at 1-866-608-8080, or GMC at 1-866-996-9463.

Seat Belts
Model year 2002
Certain light duty pickup trucks and sport utility vehicles fail to conform to Federal Motor Vehicle Safety Standard No. 209, "seat belt assemblies." One of the two sensors in the driver's and front passenger's seat belt retractors could be inoperative. The seat belt retractors will lock when the belt webbing is extracted during a crash; however, the mechanism that locks the seat belt retractor when the vehicle decelerates quickly, such as heavy braking, may not operate as intended.
Consequence:
If this were to occur, the safety belt may not restrain the occupant as intended during a crash, and could result in injury to the occupant.
Remedy:
Dealers will inspect the driver and front passenger safety belt retractors, and replace them if necessary. Owner notification began on June 24, 2004. Owners should contact Chevrolet at 1-800-630-2438, GMC at 1-866-996-9463, or oldsmobile at 1-800-630-6537.

Visibility › Windshield Wiper/Washer
Model years 2002–2003
Certain sport utility vehicles have windshield wiper systems that will not turn on, cease operation while in use, fail to turn off/on by themselves (moisture sensitive wiper system), or have continuous windshield washer pump operation because the presence of water within the wiper modules can either cause a short circuit or can lead to the corrosion of components within the module.
Consequence:
Depending on the occurrence and weather situation, driver visibility could be reduced, which could result in a crash.
Remedy:
Dealers will cover the windshield wiper module vent hole with a patch. Also, the wiper motor, circuit board, and electrical connector will be inspected to signs of water intrusion and/or corrosion and be replaced as required. The recall began July 6, 2004. Owners should contact Chevrolet at 1-800-630-2438; oldsmobile at 1-800-630-6537; or GMC at 1-866-996-9463.

Equipment › Other › Owners/Service/Other Manual
Model years 2002–2003
Certain minivans, passenger and sport utility vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard No. 225, "child restraint anchorage system." The owner's manual does not explain the meaning of the location symbols for the child restraint lower universal anchorage system.
Consequence:
This does not meet the requirements of the standard.
Remedy:
Owners will be provided with a supplement for their owner's manual. This supplement describes and shows the location symbols for the child restraint anchors that are located in the vehicle and on the child restraint or booster cushion. Owner notification began August 18, 2003. Owners should contact Buick at 1-866-608-8080, Cadillac at 1-866-982-2339, Chevrolet at 1-800-630-2438, GMC at 1-866-996-9463, Pontiac at 1-800-620-7668, or oldsmobile at 1-800-630-6537.

Reported Apr 23, 2003
Service Brakes, Hydraulic › Foundation Components › Hoses, Lines/Piping, and Fittings
Model year 2003
Certain sport utility vehicles were built with a left-front brake pipe with a circumferential score at a random location along the length of the pipe as the result of the manufacturing process. If the brake pipe partially or fully fractured, brake pedal travel would immediately increase and front brake performance would be reduced.
Consequence:
If braking performance is reduced, a crash could occur.
Remedy:
Dealers will replace the left-front brake pipe. Owner notification began on May 29, 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact Chevrolet at 1-800-222-1020, GMC at 1-800-462-8782, or oldsmobile at 1-800-442-8006.

Electrical System › Wiring › Interior/Under Dash
Model year 2002
Certain sport utility vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standards No. 101, "control location, identification, and illumination" and No. 208, "occupant crash protection." These vehicles have an intermittent condition during vehicle start-up in which the instrument panel cluster may not properly power up, resulting in most of the displays, telltale lights, and functions (except the service engine light, turn signal indicators, and the instrument panel cluster backlighting) being inoperative.
Consequence:
These vehicles do not comply with the standard.
Remedy:
Dealers will reprogram the instrument panel cluster. Owner notification began May 29, 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact Chevrolet at 1-800-222-1020, GMC at 1-800-462-8782, or oldsmobile at 1-800-442-6537.

Power Train › Automatic Transmission
Model years 2002–2003
Certain sport utility vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard No. 114, "theft protection." These vehicles are equipped with a mechanical override that could allow the ignition key to be removed with the shift lever in a position other than park. In addition, these vehicles have an override that can allow the transmission to be shifted out of park with the ignition in the off position.
Consequence:
These overrides are not permitted unless the vehicle has a locking steering column.
Remedy:
Dealers will eliminate these conditions by disabling the overrides. Owner notification began on May 29, 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact Chevrolet at 1-800-222-1020, GMC at 1-800-462-8782, oldsmobile at 1-800-442-6537, or Hummer at 1-866-486-6376.

Air Bags › Frontal › Driver Side › Inflator Module
Model year 2003
On certain mini vans, passenger and sport utility vehicles, some of these vehicles have a driver's side air bag that may not deploy as designed. In addition, the air bag inflator could rupture.
Consequence:
This could result in reduced capability of the air bag to protect the driver. Also if the air bag inflator ruptured, pieces of the inflator could strike and injure the vehicle occupants.
Remedy:
Dealers will inspect, and if necessary, install a new driver's air bag. Owner notification began on March 11, 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact Buick at 1-800-521-7300, Cadillac at 1-800-458-8006, Chevrolet at 1-800-222-1020, GMC at 1-800-462-8782, or Pontiac at 1-800-762-2737.

Structure › Body
Model year 2002
Certain sport utility vehicles are missing welds on the rear floor plan.
Consequence:
In a crash, missing welds could degrade performance of the third row seat and safety belt anchorage and occupants could receive greater injuries.
Remedy:
Dealers will inspect the vehicle for missing welds. If missing welds are found, GM will exchange the vehicle for an equivalent vehicle or provide a refund of the purchase price. Owner notification began October 4, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact Chevrolet at 1-800-222-1020 or GMC at 1-800-462-8782.

Reported Aug 23, 2002
Fuel System, Gasoline › Delivery › Hoses, Lines/Piping, and Fittings
Model year 2002
On certain sport utility vehicles, a fuel filter fitting can become disconnected. If this were to occur while attempting to start the engine, a no-start condition would result and fuel would be pumped out the fuel filter onto the ground.
Consequence:
If the fitting becomes disconnected while the vehicle is in motion, the engine would stop due to inadequate fuel supply and cause a loss of power steering assist. If an ignition source were present, fuel leakage from a disconnected fuel filter fitting could result in a fire.
Remedy:
Dealers will replace the fuel filter quick connect retainers. Owner notification began September 20, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact Chevrolet at 1-800-222-1020. GMC at 1-800-462-8782, or oldsmobile at 1-800-442-6537.

Air Bags › Frontal
Model years 2002–2003
Certain passenger, mini vans, and sport utility vehicles have an air bag inflator on the driver's side that could fracture at a weld during a deployment.
Consequence:
Pieces of the inflator could strike and injure vehicle occupants and the air bag cushion would not inflate fully, reducing the capability of the bag to protect the driver.
Remedy:
Dealers will inspect, and replace, if necessary, the air bag module assembly on the driver's side. Owner notification began August 15, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact Buick at 1-800-521-7300, Cadillac at 1-800-458-8006, Chevrolet at 1-800-222-1020, GMC at 1-800-462-8782, oldsmobile at 1-800-442-6537, or Pontiac at 1-800-762-2737.

Power Train › Transfer Case (4-Wheel Drive)
Model year 2002
Vehicle description: sport utility vehicles equipped with 4-wheel drive. The calibration of the transfer case control module could cause insufficient high speed gear engagement.
Consequence:
If the gear is not engaged, the vehicle can roll when the transmission is in "park" and a crash could result without warning.
Remedy:
Dealers will update the transfer case control module calibration to increase gear engagement. Owner notification began November 6, 2001. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact Chevrolet at 1-800-222-1020 or GMC at 1-800-462-8782.

Power Train › Transfer Case (4-Wheel Drive)
Model year 2002
Vehicle description: sport utility vehicles (4 wheel-drive). Some of these vehicles were built with a range shift collar in the transmission transfer case that contains cracks.
Consequence:
This condition could result in a complete fracture of the range shift collar and subsequent loss of vehicle forward and reverse gears, and the inability to maintain "park" position. This increases the risk of a vehicle crash resulting from unintended movement of a parked vehicle.
Remedy:
Dealers will replace the transfer cases and update the control module calibration. Owner notification began September 6, 2001. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact Chevrolet at 1-800-222-1020 or GMC at 1-800-462-8782.

Recall text is shown as NHTSA publishes it; older campaigns, which NHTSA stores in capital letters, are shown in sentence case. NHTSA’s Vehicle Safety Hotline, 1-888-327-4236, also answers recall questions.

How to read this recall list

This list shows every safety recall campaign NHTSA has on file for this make, model and model year. It is not specific to one vehicle: a recall often covers only vehicles built in a certain date range or with a certain part, and many of the vehicles it covers will already have been repaired.

What each recall field means

What each recall field means
Field	What it tells you
Campaign number	NHTSA's unique ID for the recall, such as 20V771000. Quote it to a dealer or when searching NHTSA's site.
Component	The system or part involved, for example air bags, brakes or electrical software.
Summary	What the defect or non-compliance is and which vehicles are covered.
Consequence	The safety risk if the problem isn't fixed.
Remedy	What the manufacturer will do, such as a repair, replacement or software update, and whether it is free.

Some recalls carry an NHTSA consumer advisory, “Do Not Drive” or “Park Outside”. Follow it until the repair is done.
A single campaign often covers several models or model years, so the same campaign number can appear in more than one list.
Recalls are shown as NHTSA publishes them. Very recent campaigns may take time to appear.

Does your vehicle have an open recall? Only a VIN check can tell you. Enter the VIN at NHTSA's recall lookup (opens in a new tab) or on the manufacturer's website. Our VIN recall check guide explains what each option covers.

Not necessarily. Each campaign lists specific model years, and many cover only vehicles built in a certain period or fitted with a certain part; repairs already carried out aren’t shown. To see whether a recall is open on your vehicle, enter its VIN at NHTSA’s recall lookup (opens in a new tab) or ask a Chevrolet dealer.
