My wife and I were just driving and suddenly the motor started stopping installing. We managed to get over toward the curb and shut the motor off and restart it. Then it ran normal. When it did stall out, and we made it to the curb, it shut itself off. That was yesterday then this morning it started to do it a little bit when we left the house.

Steering assist reduced light came on, fan kept running after shutting off, brought to dealer to see if it was covered under the gm special coverage for thermostat, they say the radiator needs to be replaced for a leak. I looked it was leaking a bit on the top driverside corner, not actively leaking but a bit of corrosion where it had. So they want to replace the thermostat(covered under gm special coverage), the fan and radiator also replaced. From what I have read online this is a known issue with these radiators leaking at the seams. People end up replacing the radiator multiple times and still leaks. How can they get away with selling these cars with junk radiators and not recalling.
