Check engine light came on and I noticed that the cooling fan would continue running for several minutes even after turning vehicle off. Had a mechanic run the diagnostics and the code came back as a thermostat/cooling issue. Although when I called to make an appointment and told him the issue and that it was a 2021 Traverse, he knew exactly what the issue was. He said that is a very common issue in all 2021 Chevy/GM engines. Online research provided a couple special coverages for repairs on 7 different GM vehicles from that same time period. Of course, the Traverse is one that is not included. Seems fairly obvious this was a GM engine issue from all vehicles in the 2021-2023 timeframe. Not sure how they can only pick out 7 models, but I am hoping an update can be made to add the Traverse and any other GM models that have that same 2021 engine.

I am filing a safety complaint regarding two vehicles provided through Bob Hook Chevrolet in [XXX] . My Chevrolet Traverse has been at the dealership for approximately one month due to a transmission failure. The vehicle has remained unrepaired during that time. The transmission issue has made the vehicle unreliable and unsafe to operate. While my Traverse was in the shop, the dealership provided me with a Buick Enclave loaner vehicle. On Thursday, while driving the Enclave, the vehicle repeatedly stalled. The entire electrical system shut down, and the power steering failed and locked up. This created a very dangerous situation and made it difficult to safely control the vehicle in traffic. After reporting the breakdown and safety concerns, the dealership’s only solution was to return my Chevrolet Traverse to me even though it had not been repaired. I am concerned about the serious safety risks involving sudden stalling, electrical failure, loss of steering assist, and unresolved transmission problems. I request that these issues be investigated to determine whether defects exist that could endanger other drivers.

While driving, the steering wheel became very hard to control. A system warning came up on the dashboard screen stating that the steering wheel was not working. With an 18-wheeler coming up behind me the decision to pull over was made. The left hand turn into an auto part store was made with much difficulty and so was trying to park. Gentleman inside inspected the vehicle and highly recommended NOT driving the vehicle since it was a safety issue not only for myself but others as well.

The car sometimes will not accelerate in the 25-35 mph range and will begin to shudder and shake. This can be very dangerous when attempting to merge on a highway. This also happens when completely stopped and and then accelerating. It will shake and shudders until or not accelerate at all forcing you to take your foot off the gas and reapplying pressure slowly or slower than what should be. This shuddering can also happen at higher speeds as well. This will likely cause an accident at some point if this continues.

What component or system failed or malfunctioned, and is it available for inspection upon request? My wife and daughter were both involved in a car accident. My wife was driving the speed limit (30-35 mph) when a car traveling in the opposite direction turned left into her lane, cutting her off, and causing a collision of the two vehicles. The front driver side of the Traverse contacted the other driver's passenger side. Upon collision, none of the airbags deployed. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? My wife hit her face on the steering wheel and suffered a fractured nose, excessive bleeding, and head/neck pain. My daughter has bruising on her legs. Has the problem been reproduced or confirmed by a dealer or independent service center? No Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Police and paramedics responded to the scene and a police report was generated.
