2019 Malibu LT Electric Issues
So about 3 weeks ago my car started doing some weird electrical stuff. The wipers would activate while driving down the road, AC controls wouldn’t work on the dash and lights would turn on and off. The next day my car completely died, and the horn would go off randomly. Next thing I know I’m having AAA change the battery but the car still wouldn’t turn on (no lights, no power). I had it towed to a shop and they said it was the Body Control Module. The shop replaced and reprogrammed it, but lo and behold the car was still having issues. The wipers wouldn’t shut off when the car was on, and the TPMS and safety restraint lights were still on the car. Lastly, the car was parked at my house and off and the horn would randomly honk loudly. I had a locksmith make a new key as the shop indicated a second key was required to complete the programming. I also disconnected the negative battery terminal so I didn’t drain the battery. The shop who installed the BCM refuses to acknowledge any issues and will not make any repairs. What are your thoughts on the root cause?
