Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

Latest Feb 25, 2021
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

Feb 25, 2021
33,838 units potentially affected
The defect: General Motors LLC (GM) is recalling certain 2020 Buick Enclave, Cadillac XT4, XT5, Escalade, Escalade ESV, Chevrolet Suburban, Tahoe, Traverse, GMC Yukon, Yukon XL, 2018-2021 Chevrolet Express, GMC Savana, 2019-2020 Chevrolet Blazer, Silverado 1500, GMC Acadia, Sierra 1500, and certain Continental tires sold to the aftermarket for various model year 2018-2021 vehicles. The affected tires were cured for too long during production.
The risk: Over cured tires may develop a break in the sidewall resulting in sudden air loss or a belt edge separation which could lead to a tread/belt loss. Either condition can cause a loss of vehicle control, increasing the risk of a crash.
The remedy: GM will notify owners, and dealers will inspect the tires, replacing them as necessary, free of charge. The recall began March 22, 2021. Owners may contact GMC customer service at 1-888-988-7267, Buick customer service at 1-866-608-8080, Chevrolet customer service at 1-800-222-1020 or Cadillac customer service at 1-800-458-8006.

I was driving into a parking lot when my back passenger side window imploded like a rock was thrown at it, but no rock and nobody in sight. I looked all around for a cause but believe it somehow spontaneous shattered. Thankfully 3 minutes prior I had dropped my kids at school otherwise there would have been injury I am sure.

Electronically controlled thermostat and sensor fail or get stuck at a much lower coolant temperature causing the dash to display the “steering assist is reduced drive with care.” It isn’t just a message, the steering is much harder to use potentially causing an accident. The ac completely doesn’t work causing potential for sensitive, elderly, or young children and pets to overheat inside, it’s significant risk of injury or death from the hot summer temperatures. The engine coolant temperature gauge is all the way down on C position which isn’t registering how hot/cold the engine gets potentially causing damage to the vehicle and a total loss of the vehicle entirely due to damage from the engine overheating. GM sent out letters to 2021 blazer owners which included a special coverage number N252508350 applying to people with this year having this problem and they have until 2036 or 150,009 mi to get the repairs made free of charge, they just bring the document with the special repair codes to the dealer and they fix it free of charge. After doing research online, this problem is affecting all years of the 2019+ blazers with the 3.6L V6 engine AND other known problems with other models and years of their other lineup of cars, it’s very widespread across their platforms. So what are people supposed to do when it isn’t the 2021 year? Pay an $800+ repair bill to GM when they KNOW it’s more widespread than just this year/make? This is a scam. I can’t even do the repair myself because I’m having trouble finding the correct parts online and not only that the repair is extensive, the whole top half of the engine needs to be taken apart just to get to the thermostat, we’re talking the airbox and intake manifold, all the plastic parts and shrouds and sensors covering engine, the fuel rail and injectors, pipes and clamps, engine coolant needs drained and refilled. It’s a major fix. I’m reporting this complaint to raise awareness and hopefully GM will do the right thing.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
