Weird electrical problems,i have taken to 2 different people, 1 of which specializes in transmissions, the problem is that when the vehicle is warmed up the transmission doesn't know what gear it is in, on initial investigation the problem appears to be the trottle position sensor but that was replaced and still no fix. They hooked up computers to the car while driving and say the computer doesn't read the tps being operative during driving but no problems can be found with the wiring and computer board.

My quest would take a long time to get heat into the interior. Recently it started overheating as well. I replaced the thermostat, but all the instructions say to install the thermostat so the spring is facing to the inside of the engine. However, the t'stat listed for this vehicle will not fit with the spring to the inside of the engine; and the original t'stat (i don't think it has ever been replaced - it had nissan on it) was installed with the spring end facing the hose end. So I installed a shorter t'stat...

The head of a bold holding the head to the engine block failed. The loose bolt head then jammed the cam shaft preventing the cam shaft from rotating. When starting the engine, the timing belt broke at the drive shaft damaging valves since the engine is a "non-clearance" engine. The bolt failed by fatigue which is evident in the failure surface. The fatigue failure originated at a location just under the bolt head due to a manufacturing defect. It is estimated that the repair will cost about $2000.

The vehical has failed on me four times since I purchased it used in early 2000, while operating under heavy strain at higher elevations, the engine quits dead with no notice of the on coming failure, I have had it into a dealer twice for the same problem and they can not diagnose the problem.It is dangerous and possible a deadly situation for me and my family. I have had the fuel pressure regulator checked and checks ok. I would not nor will not sell this car to anyone under it's current condition.*Ak

The fuel tank vent line flexible rubber hose between the fuel tank and the metal vent pipe developed at least two cracks in it. This is causing fuel to leak out of this connecting hose when the vehicle is refueld. This leakage occurs until the level in the fuel tank is low enough that it is below the flexible hose.

While traveling with window open consumer noticed raw gas odor inside vehicle. Dealer has been contacted. *Ak.Et.
