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.
I have a 2021 Chevy Traverse LT. The stereo touch screen keeps completely freezing. We've brought it to the dealer who told us it was working fine. Its frozen twice. Once we had to pull the fuse out to reset it for it to work. Vehicle has a rattle at startup and suspension squeaks. Captain seats almost seem loose, they rattle at times. The brakes are horrible, they squeak all the time. Pads are not worn, but it appears from my mechanical knowledge that the pads are slightly oversized to the rotor or not set on straight and they're rubbing the unmachined part of the rotor which could contribute to the brake issue. Dealers have claimed before its just ceramic rub, however; I have done tons of brake jobs and ALWAYS use ceramics. NEVER had a problem with that. Vehicles need a MAJOR recall for all these systems as they can all be a major safety concern. …
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. …
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. …
Vehicle: 2021 Chevrolet Traverse Problem: Persistent "Shift to Park" message when vehicle is in Park I own a 2021 Chevy Traverse and have experienced repeated incidents where the dashboard displays "Shift to Park" even though the gear shifter is securely in the Park position. This prevents me from turning the vehicle off and has caused battery drain and confusion about whether the car is fully secured. This issue is clearly known by GM, as evidenced by a Technical Service Bulletin (TSB #19-NA-206 and others). It affects multiple model years and has prompted a class action lawsuit. Despite the widespread nature of this defect, GM has not issued a recall. I believe this issue presents a safety concern, particularly for drivers unaware that the car may not fully power down, and due to the potential for battery drain and immobilization. …
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 NHTSA. Shouldn't have electrical failures on cars with 23,000 miles.
The vehicle does not recognize when the vehicle is shifted to park. It states "shift to park" when the vehicle is already shifted to park. When this happens and the push to start button is pressed to shut the vehicle off, the vehicle will not shut off which becomes a major issue as the car continues to run and the vehicle's battery will die since the vehicle will not fully shut off. This is a safety hazard because the vehicle can end up with a dead battery when this happens. I've looked this issue up online and it is a common issue that Chevy has failed to address.
