Spouse driving the vehicle indicated that the temperature gauge on the vehicle had risen quickly while sitting idle at a stop light. The gauge only decreased slightly when the vehicle was in motion. Suspected a thermostat. Took the vehicle to the dealer, they indicated the same. Replaced the thermostat and the problem continued. Tests indicated a blown head gasket. The vehicle had no symptoms of this issue. No loss of coolant. No coolant in the oil. No oil in the coolant. No white smoke from the exhaust. The only indicator was the quickly rising temperature. At that point, no preemptive measures could be taken to fix the problem.
The same problem has been occurring for over a year. Where I go to start my car, my key turns over but the engine never kicks on. Its makes an odd noise, not grinding but a noise. It takes about 6-7 times before the vehicle will kick on. Once it finally starts there is black smoke and fluid coming out of the exhaust pipe. The rpm's rev up to 8k than down to 4k, the car idles and sounds like it wants to die. I have brought my car back and forth to the dealership 6 times since April 15, 2008. So far nothing has been done and they state the car is up to gm standards. I have wasted much time and money into this issue and soon the car will be out of warranty. I have a feeling that once the warranty is up that they will charge me an arm and leg to get it fixed. I have a 2006 Chevrolet Equinox will a little bit under 34k miles.
