Filed Jun 25, 2026 · CA

On [XXX] I purchased the vehicle from Bakersfield Hyundai within days I reported break failure and notified them about a noise that was coming from the SUV that sounded like a mini motorcycle, they first said (Xavier) that the noise would go away because it had just gotten serviced but they kept me there for four plus hours and said I had to take it back which I did and again I took it for break replacement and I told them the noise would get louder and sometimes it would smell inside the vehicle like vinegar again they did nothing they falsely said I declined to stay because of time Which I didn't I asked if they were able to provide me with a vehicle while mine could get serve since I have children that attend school to who they said no, so I couldn't stay longer I had to pick up my children from school this is my only vehicle so Hyundai would not do anything about the breaks nor that sound the vehicle started making beeming noises from across the dashboard the main screen freezes and not to mention the vehicle stalls I have to jump start it, also when I sent Hyundai a video of the exhaust pipe ruptured they automatically contact Chevy and vehicle has to be towed to them there was a very strong oder of vinegar and rotten eggs coming into the cabin to which I had let Hyundai dealership know but they didn't document they said I had to take it to Chevy now they replaced the pipe but the vehicle still has issues starting up the screen still freezes and once in a while I still get that smell of vinegar in the cabin I have paperwork from Chevy and Hyundai I also have video, pictures and txt from Hyundai personal admitting to knowing about the pipe leak not to mention I was exposed to this for about 40 minutes I had driven my children to school I had my OBGYN appointment to which I informed my doctor I was experiencing a headache and dizziness I thought it was because of early pregnancy not knowing it was carbon monoxide I miscarried that following day 4/13/26.

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.

Received a "Service Battery Charging System" dash warning message driving down the highway. Made it home and changed the battery but the issue persists and I can't drive the car. Reading online many complaints/problems with alternator and electrical premature failures. Car is a little more than 4 years old and has only 23,600 miles. Getting the car to the Chevy dealer tomorrow to diagnose problem and fix. If car were to stall out at highway speeds it could be very dangerous. This problem should receive further investigation by the federal safety agency. Shouldn't have electrical failures on cars with 23,000 miles.

My car came up with an alert message when I started the vehicle, "Service Battery Charging System Vehicle May Stall". I assumed using my remote start had somehow drained my battery or that the cold weather (30 degrees) was affecting my battery. I began driving hoping the battery would charge once running. Another alert came up, "Battery Saver Active". The alerts repeated again. In less than 10 miles from where I first started, I made it to a Les Schwab where I asked them to check my battery. The guy ran out and said my battery had more juice not running. They told me to take it to service repair shop close by. I began driving to the nearest shop and my car jerked/stopped/died, the steering was locked up and I lost complete control of the vehicle but luckily I was not far out of the Les Schwab parking lot and was able to coast into another parking area. I had to have my car towed to the repair shop where they told me it would cost $1,600 to replace the alternator, I luckily have a Platinum Extended Warranty and it appears to be covered. I am so thankful that I was not on a highway at the time and that I took the alert seriously and responded immediately. My 14 year old was in the car with me and it really scared her that the car jerked and stopped. The amount of time I had from receiving the alert to a dead battery was very short. This should not happen and I'm so glad that I was driving versus an up and coming driver (turns 15 next week) that would not have known what to do. I've done my research and this issue has been mentioned in several chats regarding owners experiences for Traverses' around the 30,000 mile mark, my car is at 40,000 miles and was serviced at 30,000. I'm honestly not sure I can ever trust my vehicle after this experience. Others have said that they fixed the issue only to have it happen again.

When leaving work last night, a warning appeared saying 'Service Charging System Vehicle May Stall' and shortly after another showed "Battery Saver Active" so I went to my local auto parts store and had the battery replaced for $300. The gentleman also ran a test on the alternator and it came back with a failure on the voltage regulator but all others were good. I drove home hoping drive cycles would clear it out. I drove to work this morning getting the same errors and voltage not going above 12.0, dipping all the way to 11.5. So now, I have to replace the alternator, praying it does not shut off on the highway and I get hit and killed. I have seen numerus incidents online of the exact same issue. I bought this car brand new (my 1st ever) in 2021, I only have 25,000 miles on it, she is garage kept and very well taken care of, this should not be happening on a practically new car. Please do something before more get injured or even killed.

I bought my 2021 Chevy Traverse brand new. Now it has about 44,000 miles on it and is just under 2 months of purchase date. I noticed that my battery light turned on yesterday while I was driving. Within seconds my vehicle stalled out and I was just coasting along in traffic, unable to restart my car. I was able to coast to the side of the freeway and jump my car. After doing so it started again so I proceeded to drive away. After about 4 more minutes my vehicle shut off again as I was driving in traffic. I was unable to get the car started again and was just a sitting duck in heavy traffic. I had the vehicle towed and a new battery was put in. My vehicle starts but the new battery is already loosing voltage. After a diagnostic test was done by the mechanics at the auto shop it looks like the alternator needs to be replaced. This is not only unheard of that such a new vehicle would already need a brand new alternator, but it was also a huge safety risk with how it all happened so quickly with VERY minimal warning and the vehicle completely shut off while I was driving in heavy traffic. So many people could have been harmed due to this malfunction.

Warning on dash to check charging system. Driving on highway, all lights on dash started lighting up and going crazy and then everything on dash completely shut off while I was driving. Car eventually stalled. Car has less than 40k miles and only 3 years old. Brought it to dealership and they said it needs new alternator and battery.

I bought my Chevy traverse car in June 2021 with 0 miles. On 12/25/2023 the alternator went out. I know there any many people who are having this same problem when the car reaches 40k miles. This is not fare to us bc we now have to pay 1700 in repairs. If the alternator goes out when driving, your car will stall and stop and you can end up in a sudden crash. This should not be happening at 40,000 miles.
