POWER TRAIN,ELECTRICAL SYSTEM — Filed 03/03/2026

I was at a stop light, car was stopped, the electronics on the vehicle looked like it went through a reboot, a/c blower fluctuated (turned off then back on), all displays went out and restarted like it does when you start the car. When the traffic light turned green, and I stepped on the gas, the car shuddered and hesitated, like the transmission, abs and traction control were all going haywire. Then the car drove fine. As long as I do not slow down too much or stop. Once I got home and had to back up into the garage, it went through that haywire cycle again. This was the 3rd time this has happened on this car. But after I shut off the engine, wait a little while and start it again, symptom seems to go away, until it decides to happen again. I have had this car since July of 2024, and since that time, I have had this happen to me 3 times and 2 times to my wife. I have read on the net and one of the possibilities talked about if the abs control unit, where soldered wires seems to be melting off of the circuit boards and causing intermittent connection, therefore exhibiting erratic behavior. There are even services on ebay where you can send in your whole abs unit and they will open them up, clean and re-solder the wires. This seems to be scary and concerning from a safety perspective. Please investigate the issue for us who are affected. Occurrences are getting more frequent (almost every other day) and it just happened again today 3/3/26.
