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.

On [XXX], Onstar did an Auto Unlock on my car. After the car was opened, the entire radio panel didn’t work. On June 13th, Bob Johnson replaced the Onstar telecommunications module. Only the radio worked with the screen black for a couple of minutes. Then it stopped working. They stated that they ordered the part, but every time I call, they haven’t.

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. I urge the federal safety agency to investigate whether a recall is warranted

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.

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.
