Tire Pressure Monitoring System problems of the 2008 Chevrolet Malibu

Started the car to come out of a parking spot, heard humming/rattling noise. Steering wheel started to vibrate then would do rapid half-turns by itself, jerking left and right. Shut the car off and restarted. Seemed ok for first few minutes then started again. Got on the road, driving about 35-40 mpg on highway and it became uncontrollable. Could not keep it straight within the lane. Almost hit a car in the lane on my right! pulled up to an auto shop near by. They test drove and experienced the issue but explained that with these cars, the technology in them is too advanced and would have to be taken to a chevy dealer. Mechanic explained that the matter is quite hazardous and it would be a huge risk driving it now. Single mom driving 45 minutes from home with 2 minor children. Had to get a tow truck to get back home, 45 minutes away. $$$!! had this vehicle for 11 months only. Prior to this issue, had door locks issues as I've ready on other threads and also currently experiencing issues with faulty tire pressure sensor as well. Nothing but problems with this car since I've had it. This is my first and very last Chevrolet!!.

Several times we have had to replace the tire pressure monitoring system that should not have failed. My techs are qualified and these were defective when the customer came in, but because we showed them to the customers they felt we damaged them. It is making us not want to inflate tires. . . . And this is unsafe for the customer.

I was putting air in the tire and when I released the nozzle of the air hose the valve stem broke in half and the hose flew back and the top half of the metal part of the valve stem flew back. It missed my face and flew about 2 feet behind me. All the air came out of the tire at once. I took the tire to the GMC dealer and they replaced the part under warranty.
