ELECTRICAL SYSTEM
First sign of problem - Sept. 2021. Driving on highway at about 35 mph. Simultaneously, engine quit running, door locks unlocked and all dash lights came. In a matter of less than a second the doors relocked, forward momentum of vehicle caused transmission to kick start the engine and jolt forward rather violently. Then the dash lights went off and the vehicle resumed normal operation. This continued to happen with increasing frequency. I took the vehicle to the local Chevy dealer to set up an appointment for service. When I explained the problem to the representative, he told me that the battery was the likely cause. I went to an auto parts store and had the battery checked. It did, indeed, have a bad cell. I replaced the battery and the car operated fine for several months but the problem began to recur, infrequently at first but continued to worsen. I discovered later that the same problem also happened when when the car was sitting idling. The difference was that without the forward momentum of the car, the engine did not restart and required being shifted into neutral and started with the key. Also, when driving at a speed of less than about 30 mph, the forward motion was not enough to kick start the engine and shifting into neutral and using the key to restart was necessary while coasting in traffic. Final symptom, the above has happened only now the dash lights go out and the vehicle does not respond at all. After several minutes and several attempts the lights come back on and the vehicle runs. The car had 55,563 miles on it when I bought it and in just over 3 years, I have put 6,237 miles on it and it now sits because I am afraid to drive it. I have had the vehicle back at the dealer twice since having the new battery installed. They simply tell me that they cannot recreate to get a code and therefore cannot help.

ENGINE, FUEL/PROPULSION SYSTEM
My cars coolant is leaking and the source is unknown. My car has overheated twice and my mechanic has been unable to find what needs to be repaired. The coolant has need to to be filled twice within a 6 month period. Now my car is having other issues with the catalyst system that lead me to believe the coolant leak might be affecting these other parts. My catalytic converter was already replaced and the same code has popped up 4 months later.

The driver, and front passenger interior door handles the metallic chrome coating starts to lose its adhesive. When opening the door from the inside it cuts your hands if you don't notice it. Both door handles started to have the same issue within the same year. My children, my wife and myself all have been cut from the same problem. I tried to remove the parts that caused the injury due to us not being home and still required to use the door handles. I didn't want further injury to occur to my family.

Once again, my doors unlocked then relocked, my dashboard lights went out and the engine stalled. I was on the KU campus when this happened 3 times within 6 blocks. This is getting very scary, especially when i am in a busy area of town. No codes have ever popped up. This has been happening since May 2022. I will keep reporting, hopefully there will be a recall soon. Very frustrated with this situation!
