Fuel injector failed and pumped too much gas into cylinder causing gas to get into engine oil and ruin engine. GM claims they are building the replacement engine, but won't give any estimate of when it will be fixed. Other dealers that are receiving these engines will not sell the engine to my dealer. I believe there is a bigger problem that GM will not admit to and they should be held accountable. Four months is too long for this situation to exist!

Have had starter problems since we purchased the vehicle. Starter intermittently loudly grinds when pressed 2-3 times a week and won-??t start. Dealership could repeat problem once, but never fixed it. Took vehicle in at least half a dozen times. Never fixed. Car also makes an odd humming when gas is applied. This week, car started and died after driving a foot. Then car wouldn-??t start at all. Brakes stiffened up and wouldn-??t compress without substantial effort. Everything resolved on its own within 30 minutes. But the very next day, pulled inti position in our alley to back our Suburban into the garage. Put car in reverse. While using the back up cam (that came on like normal when car is in reverse), i applied gas. The car didn-??t respond at all (didn-??t even rev like what happens when you apply gas while car is in neutral). I applied a touch more gas and car all of a sudden lurched forward with the full force of a V8 engine being floored. I tried to slam on the brakes, but the brakes wouldn-??t respond in such a way that i thought my shoe must have gotten stuck. It hadn-??t. The brakes did not work. I don-??t know how long it would have taken to finally stop because we only had 5 feet to go before we slammed into our neighbor-??s house (which is what stopped our vehicle). Car is not drivable and I wouldn-??t drive it if it were. It is available for inspection. Will be towed once scheduled.
