Check Engine Light On problems of the 2010 Chevrolet Silverado 1500

The contact owns a 2010 Chevrolet Silverado 1500. The contact stated that engine pressure sensor slave switch failed three times. A dealer was not contacted. The failure recurred two additional times with the check engine warning light illuminated. The manufacturer was notified of the failure however, referred the contact to the NHTSA to file a complaint. The failure mileage was approximately 100,000.

My husband and I were driving about 45 mph down a steep hill, towing a utility trailer, on sr87 in the mountains when the door locks clicked and the engine turned completely off with no warning. The steering wheel locked up and the brakes did not work. My husband put the car in neutral as it accelerated down a cliff and attempted to restart it with no luck. There were no cars immediately around us so we were able to coast to a stop on a steep incline. When we got out to check it, there was oil all over the wheel wells and still no warning lights had come on. We took it to the dealership and they told us the transmission was completely blown on our 6 year old truck. There was zero explanation as to why this would happen as well as to why we had no warning prior to the engine shutting off. We were told to pay better attention to the temp. Even though it did not overheat. Chevy offered no relief or help. We were quoted a price about $2000 less for the initial transmission repair than it would have cost so we took it to a non-dealership shop to repair. This weekend, the check engine light came on out of nowhere indicating loss of power and the stabilitrack warning came on even thought that was previously repaired by a dealership on a TSB about a year prior to the transmission going out. The code it threw this time was p0305 and we were on very limited power driving back home from a road trip. Could not go more than 40 mph uphill. Extremely concerned for our safety since the vehicle can turn off with no warning. Also, the money spent is ridiculous.

This has happened twice in the last week. Today I was sitting at a stoplight with my foot on the brake and suddenly without warning my 2010 silverado accelerated and lunged forward about 3 feet. Fortunately there was not a car or person in front of me or I surely would have had an accident then the engine started missing. At the same time my check engine light came on. Service traction control, service stabiltrak, engine power reduced flashed on my dash. I limped home at 10-15 mph max! after about an hour I started it and it ran just fine "both times". The first time this happened I was in a parking lot with the transmission in park. It is now at my local Chevrolet dealer for repair.
