My 2012 Buick Verano has started stalling then restarting on its own (of course while I’m in the middle of traffic). Then recently the power steering goes out, was able to make it to the curb. Turned the car off, started the car, received messages to lower & raise the driver’s window then the passenger window, then restart the car. So, I did and was able to get home safely. Now, I’m researching to see what is causing these issues. Car was just in a dealership to replace both the
intake and exhaust sensors which apparently has not fixed the random stalling issue.
Any suggestions what to look at or do next?
