My vehicle when purchased was altered from cloth seats to leather by the dealership where purchased. 3 days ago my car is signaling me to service airbag while driving the car or in idle. So I immediately took it to a certified mechanic at meineke and was told that this is a manufacturer defect and there is a recall for this on my year, make & model SUV. I called gm on 11/29/2019 and was told by a supervisor named angel there has been no recalls by their manufacturer and there is nothing more she can do about the matter. I cannot drive my car like this knowing this can be potentially harmful and hazardous.

Received a "check engine" light while driving the vehicle. The fault code that came up was po128 ( insufficient ambient temperature - ect ) upon researching the problem I discovered that this is a common fault on this vehicle. It is generally caused by a "sticking" coolant thermostat. This condition also results in poor heating poor heating of the passenger compartment. If this is such a common problem with vehicle as I have found. Gm should issue a recall and correct the problem at no expense to the owner!

When backing the vehicle to leave a local restaurant, driver struck vehicle behind her. This happened so quickly that it was unknown to the driver how the vehicle traveled so quickly that driver had not even had a chance to turn the steering wheel to avoid striking the other vehicle. Driver placed vehicle in drive to pull over to assess the damage. When placed into drive, the vehicle lurched forward and continued to accelerate despite the brakes being applied. The vehicle struck a brick restaurant. Damage was also done to the interior bathroom of the facility and the business had to close to assure safety of it's staff/customers. Witness states the vehicle was obviously lurching and appeared to have a mechanical problem. The driver's foot bounced off of the brake pedal on impact lodging it underneath the brake pedal.
