2008 pontiac grand prix. Consumer writes in regards to catalytic converter replacement. *smd gm would not cover the cost, because the vehicle was not registered in california.
Accelerated to on ramp of expressway, reached approximately 60 MPH. Vehicle immediately decelerated. I pulled off to the side of the expressway and turned the car off. Attempted to turn car back on. It did not turn over. Battery was ok, engine was not. Car had to be towed to service center. Ignition control module, ignition coils, spark plug wires replaced. Hefty repair bill. One week later, accelerated to on ramp, reached 70 MPH, car jerked as I attempted to increase speed. Check engine light flashed rapidly twice. Got off expressway, reached speeds up to 40 MPH. Possible catalytic converter to be replaced. Both situations could have LED to serious injuries.
When I fill my car up to full tank my car doesn't start. The ignition switch takes two tries.
Eval hose caused my check engine light to come on. Got it fixed and tested and same diagnose was popping up. Check engine light is still on.
2008 pontiac grand prix engine will automatically stop running when driving. This shuts down the power steering, brakes, etc. This has happened about a dozen times over the last year. All but two times when this happened, we were able to put the car in neutral and restart the car. Two of the times, the car did not want to start - car would crank but not start. Eventually we were able to get the car stated. Over the past year this happened when we were driving in a city at approximate 30 MPH, coasting down a hill, or stopped at a stop sign. However, we did not take this car on the highway very often so we have not had this issue happen on the highway. So far, we have been lucky and had no accidents with the car. Symptom's are very similar to the gm ignition switch recall. We took the car to two repair places and the diagnostics would not show anything. We recently took the car to a gm dealer and they ran a diagnostics and they determined crankshaft position sensor code p0335. They replaced 10456161 sensor and emissions system repair. They are not 100% sure that this will fix the problem. This is a very dangerous situation and we do not allow our kids to drive the car for fear of them being killed in an accident.
The engine coolant system clogged up my thermostat and coolant turned to a brown consistency and thickened like mud. Mechanic stated that the coolant, drex, can have no fluids added, and no water unless it is distilled. I did not add any coolant or water and received no coolant low warning. I previously had car worked on one year ago for the same problem. I want all vehicles everywhere with drex for coolant recalled and repaired. Drex in the cooling system is a design flaw. I think eventually in a coolant system some moisture forms from the heating up and cooling down process of a radiator and condensation forms. This would then gum up and ruin a cars cooling system and could cause the vehicle to overheat and possible the engine to be ruined. This is the second car where I had to do repairs because the drex clogged up the radiator and made my engine overheat.
Back in december 2012 my car have not been driving correctly. I took it to the behlmann gmc dealership and they stated everything was fine. In jan I took my car in for an oil change and informed them that my car had still not been driving correctly on that same visit I had them do a diagnostic and behlmann stated that the machine didn't say anything transmission wise that was wrong. Now that it is april my car is feeling like its getting worsier and worsier and I took it to autozone and also another car shop and had them put the car on the machine. Both places are saying the error is saying my transmission is slipping and my transmission fluid is burning. I am very disappointed because while my car was under warranty which expired not to long ago I was getting the run around saying that the transmission was fine when all along it was indeed damaging.
Excessive loss of oil (none leaking), blue smoke from exhaust.

P-0411 code; air control valve solenoid. My check engine light kept going on and then would go off. This process repeated a few times. Bought new gas cap a few times. Finally, light came on and would not go off. Took it to dealer who told me it was the air control valve solenoid and it was not covered under warranty.
