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.…

   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…

   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.…

    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…

    The battery wasn't being charged which caused some problems. However, it was the alternator that was bad. Since the battery wasn't being charged and the alternator was failing, there were problems with steering and engine power which almost caused a collision at highway speeds.

    3 times in 5 days, 2021Traverse completely shut off. 2 of those times were in a busy intersection. I couldn’t even turn my flashers on and had to manually unlock my door to get out. Fortunately the third time was in my driveway. I called AAA to tow it to dealer. This is a severe safety issue and hopefully will be covered under my warranty and the extended bumper to bumper warranty.
