Each component in detail
What the reports in each category say, in the owners' own words
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
Alternator fail before 60,000 miles. Had the car almost 3 years and children in it. Apparently a known common issue yet no recall it’s not a reliable car
Odometer Fraud. The contact purchased a 2021 Chevrolet Traverse. The contact discovered that there was a mileage discrepancy after the purchase. The vehicle was a private sale. At the time of purchase, the mileage was 49,000. It was later discovered, after checking the Carfax report, that the mileage was 75,000.
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
The contact owned a 2021 Chevrolet Traverse. The contact stated that the vehicle was taken to an independent mechanic for an inspection, where a leaking oil pan gasket was diagnosed. The contact stated that the failure had also occurred on a 2019 Chevrolet Traverse he owned. Although the vehicle had been taken to the dealer two months prior, the dealer did not find the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 72,400.
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.
Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.
From owner reports, verbatim
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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
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.
Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
Right Rear upper and lower toe links broke nearly causing a serious accident when brakes were applied, vehicle pulled severely to the right causing it to swerve and narrowly missing another vehicle. The toe link failure on my vehicle which has only 29702 miles put my life and the life of my family members at risk. The vehicle was brought to our local licensed repair shop in Massapequa, NY where the prblem was diagnosed and repaired. No warning lights or symptoms occurred prior to this first incident. I researched this safety item for any recalls on this issue, however there are none currenlty on file for my vehicle but several for other Cheverolet vehicle with same toe link issue.
While going around 40mph I approached a stopped vehicle and tried to come to a stop. At this time my braking system failed, speeding the car up instead of slowing it down, this resulted in my car rear ending another vehicle. When the car accident occurred my steering wheel air bag came out but did not inflate. There were no warning lamps or messages at the time of the crash. Due to the laws in Mississippi it was declared I was at fault and the insurance company will not inspect or cover the damages.
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim

Steering
Reports naming the steering system — racks, columns, power-steering assist and steering linkage.
From owner reports, verbatim
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.
UNKNOWN Steering assist reduced has been issued to the vehicle. Upon inspection we are being told that the steering rack needs to be replaced to resolve the issue.

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. My insurance company is currently assessing the damage, and the vehicle is being held in a lot. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No

1. DRIVER SIDE EXHAUST FLEX PIPE BRAKET 2. Exhaust leak 3. Yes. It has been replicated and diagnosed. 4. No engine light. There was a rattling and increased exhaust noise. A hole in the exhaust pipe at the bracket location was found. 5. This condition seems to be a common problem with this year and make which I am now having to pay $600 to repair.
the purge valve is ticking for the past two weeks dealership informed me yesterday that it is working as designed and no codes were noted by technician. ticking noises ( which are VERY annoying) were not present when vehicle was bought about 3 months ago . The service rep informed me that although purge valve issues have been noted and taken care of by other GM models., the traverse is not part of any recall at the moment

Other / unspecified
Reports whose component NHTSA recorded as unknown, or that do not map to one of the categories above.
From owner reports, verbatim
The base does not look in place. The buttons do not look to put in position. The entire car seat slides back and forth on its base.
When this seat is first installed with the seat belt, it has a tight fit. However, the install seems to loosen for no apparent reason on its own. This occurs frequently. The seat is properly installed with pulling the slack out of the seat belt, securing the snuglock, and then locking the vehicle seat belt. I am concerned that the install will loosen in the event of an accident, and my toddler will not be properly secured. When the seat loosens, it moves more than one inch from side to side. It has even loosened so much that it began visibly lean to one side.

My front passenger seat belt has started to not latch. I have to push the button and insert the seatbelt in order for it to latch. Sometimes it will release on it’s own.
Middle seatbelt will not retract. This vehicle has not been in any accidents.

The rear sway bar linkage broke which lead to unsafe handling/ control of vehicle. I was driving and anytime I made a right turn there was a loud clunk in rear of vehicle. Concerned it will wear other parts out by this specific part not working/broke
