I went to start the vehicle and it failed to start. I found the fuel pump relay to be badly burned . On the 30 pin. The board was melted at the 30 pin spot for the fuel pump relay. I purchased a new relay from NAPA. I questioned whether they had a new replacement fuel pump. They told me it was not available only through the dealership. My concern was that where the relay was located at there was a possibility of a fire given how badly the relay and board was burned. I replaced the relay and purchased an extra...

incase this might happen again. To my surprise it happen just days later while I was driving on the expressway. I had to get off the road immediately. Engine died, no power steering. I checked the relay, it was smoking hot. I will have to have the problem resolved. There is no way a relay should ever get hot, let alone that hot. The fuel pump fuse was not effected. Why is the relay not protected from getting so hot. There is definitely a real risk of fire. No one sits in the back seat normally. But, my grandson's. This should not ever happen.

My power steering went out so my mechanic checked it out and said my pump went out so I bought a new power steering pump and pulley had it put on and that didn't fix the problem. The next day I went out of town to visit family and my car caught on fire due to the power steering fluid leaked all out on the motor and got hot enough to catch on fire. then my ignition stoped going all the way in park so I would have to disconect my battery cables so that it wouldn't run my battery down. The car wouldn't go all the way up in park making the ignition key wouldn't turn back far enough to shut my car off and lights

The car cuts off whwn you're driving it without warning. I have had the crankshaft position sensor replaced two times and it continues to fail. There are even reports in the internet that list this as a problem with this vehicle. I am afraid that someone will hit me from the rear and cause me injury or death. I am about to have this sensor replaced for a third time. It's absolutely ridiculous that I have to keep spending money out of my pocket for the same thing over and over again. This incident is a continual problem. It doesn't matter if you're stopped or driving it just happens out of the blue with no warning.

Aluminum v8 engine leaking oil profusely. Now getting smoke and odor while driving. My concern is that oil is leaking on to the hot exhaust manifold and could possibly ignite. I suspect engine bolts need to be retorqued which would necessitate engine removal to accomplish. This is a major design flaw which needs correcting. Leaks occur during all phases of operation. The leaks first became evident several years ago and have progressively worsened since.

The engine it's shutting off while driving, and after it gets cold it will restart, but after driving again another few miles it will shut off again. There are no lights on, so no mechanic to tell me what the problem is. I even called the dealer, and I was told that they can't diagnose the car because is no check engine light on.. I tried few different auto shops with no answer, so my car is parked in the driveway because I'm scared to drive it, I don't know how or when the engine will stop.. Another mechanic told...
