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.

  1. NHTSA campaign 20V721000

    Reported

    Electrical System › Wiring; Engine and Engine Cooling › Cooling System › Hoses/Lines/Piping/Fittings

    Model year 2020

    Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2020 NPR-HD (Crew Cab) and Chevrolet 4500 (Crew Cab) vehicles equipped with 6.6L gasoline engines. The chassis harness and the coolant return hose from the radiator to the reservoir (surge hose) may chafe. Continued chafing could cause wear in the harness and/or hose, ultimately causing a hole in the hose with the potential for engine coolant to leak and/or causing damage to the harness with the potential for a short circuit.

    Consequence:
    Leaking engine coolant and/or a damaged wire harness may result in a no-start condition, an engine stall, or an electrical short. These scenarios increase the risk of a crash or fire.
    Remedy:
    Isuzu and Chevrolet will notify their respective vehicle owners and dealers of this recall, and specifically of the need to adjust the positive cable in subject vehicles, and owners will be informed that the recall repairs will be done free of charge. The recall began December 11, 2020. For additional information, Isuzu owners may contact Isuzu Customer Relations at 1-866-441-9638 and Chevrolet owners may contact the GM Medium Duty Truck assistance line at 1-800-862-4389. Isuzu's number for this recall is V2006.

  2. NHTSA campaign 20V720000

    Reported

    Electrical System › 12V/24V/48V Battery › Cables

    Model year 2020

    Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2020 Isuzu NPR-HD Gas (Crew Cab) and 2020 Chevrolet 4500 (Crew Cab) trucks equipped with 6.6L gasoline engines. The positive cable connecting the battery to the starter may be too long and may have been routed too close to the right-side exhaust pipe.

    Consequence:
    Over time, heat from the exhaust pipe may cause the conduit and insulation to deteriorate, exposing the wires, possibly causing a short circuit which could result in a no-start condition or a fire.
    Remedy:
    Isuzu and Chevrolet will notify their respective vehicle owners and dealers of this recall, and specifically of the need to adjust the positive cable in subject vehicles, and owners will be informed that the recall repairs will be done free of charge. The recall began December 11, 2020. For additional information, Isuzu owners may contact Isuzu Customer Relations at 1-866-441-9638 and Chevrolet owners may contact the GM Medium Duty Truck assistance line at 1-800-862-4389. Isuzu's number for this recall is V2005.

  3. NHTSA campaign 19V647000

    Reported

    Electrical System › Wiring

    Model years 2017–2019

    Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2017-2019 N-GAS HD and Chevrolet Low Cab Forward 3500 and 4500 vehicles and 2018-2019 Isuzu FTR and Chevrolet Low Cab Forward 6500XD vehicles. The power supply bolt in the relay box may not have been properly tightened during harness production at the supplier. This may lead to melting of the power wire and/or a loss of electrical power to the vehicle, which can lead to a stall.

    Consequence:
    A stall can increase the risk of a crash.
    Remedy:
    Isuzu will notify owners, and dealers will inspect the relay box power supply bolt, tightening it as necessary. If the harness or relay box is found to be damaged, it will be replaced or repaired, free of charge. The recall began October 24, 2019. Owners may contact Isuzu customer service at 1-866-441-9638. Isuzu's number for this recall is V1905.

  4. NHTSA campaign 19V064000

    Reported

    Electrical System › Instrument Cluster/Panel

    Model year 2019

    Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2019 Isuzu NPR-HD, NPR-XD, NQR, NRR, Chevrolet 4500HD, 4500XD, 5500HD, and 5500XD. The odometer accurately measures the distance traveled in miles, but erroneously indicates that they are kilometers in the LCD display instead of miles.

    Consequence:
    An incorrect odometer reading could lead to an unintended delay in critical safety related maintenance, potentially impairing the safe operation of the vehicle and increasing the risk of a crash.
    Remedy:
    Isuzu will notify customers and dealers to inspect the odometer LCD on their vehicle. If the distance traveled is listed as 'mi' (miles), the customer or dealer will be requested to inform Isuzu and the recall for that vehicle will be deemed complete. If the distance is listed as 'km' (kilometers), the customer will be requested to take the vehicle to the dealer, and the dealer will replace the meter cluster with one that indicates 'mi' (miles). The new odometer will be reprogrammed to reflect the number of miles traveled that was indicated on the original odometer. The recall began March 13, 2019. Isuzu owners may contact Isuzu customer service at 1-866-441-9638, GM owners may contact GM customer service at 1-800-862-4389.

    Reported

    Equipment

    Model years 2016–2018

    Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2011-2017 Isuzu NPR, 2008 NPR HD and NPR-HD Gas, 2011-2018 NPR HD and NRR, 2015-2018 NPR XD, 2012-2018 NQR, 2012-2017 NPR Gas and NPR-HD Gas, 2016-2017 Chevrolet Low Cab Forward 3500 HD, 3500 and 4500 and 2017-2018 Chevrolet Low Cab Forward 4500 HD, 4500 XD, 5500 HD and 5500 XD vehicles, equipped with certain Walter Kidde Plastic-Handle Fire Extinguishers, models FC10 and FC110. These extinguishers may become clogged, preventing the extinguisher from discharging as expected or excessive force may be needed to activate the extinguisher. Additionally, in certain models, the nozzle may detach from the valve assembly with enough force that it could cause injury and also render the product inoperable.

    Consequence:
    In the event of a fire, if the fire extinguisher does not function properly, it can increase the risk of injury.
    Remedy:
    Isuzu will notify owners, instructing them to contact Kidde to get a replacement fire extinguisher, free of charge. The recall is expected to begin in December 2017. Owners may contact Isuzu customer service at 1-866-441-9638 or Walter Kidde customer service at 1-855-262-3540 or they may also visit www.kidde.com and click on "Product Safety Recall" to order replacement fire extinguishers free of charge. Isuzu's number for this recall is V1705. Note: This recall includes fire extinguishers provided as a remedy for previous Isuzu recall 15V778.

  6. NHTSA campaign 16V797000

    Reported

    Vehicle Speed Control › Accelerator Pedal

    Model year 2016

    Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain model year 2014-2016 Isuzu NPR and NPR HD vehicles manufactured August 26, 2013, to November 11, 2016, and 2016 Chevrolet Low Cab Forward 3500 and 4500 vehicles manufactured July 27, 2016, to November 11, 2016. The affected vehicles have a throttle pedal that may get stuck under the steel stopper bolt, causing the pedal to remain in the full throttle position. Note: In gasoline models only.

    Consequence:
    A stuck open accelerator pedal may result in very high vehicle speeds and make it difficult to stop the vehicle, which could cause a crash, serious injury or death.
    Remedy:
    Isuzu will notify owners, and dealers will remove and replace the stopper bolt with a flanged plate, to prevent lateral movement of the throttle, free of charge. The recall began November 14, 2016. Owners may contact Isuzu customer service at 1-866-441-9638.
