Purchased November 2001, had two recalls for fuel system within two months, dealer told me there was previous recall fixed before I purchased. Engine safety warning light has come on and stayed on several days on seven (7) separate occasions. Dealer claims not to worry cannot figure out why. Plus seat heater went out and had to be replaced, interior heater stopped working except defrost. I believe they are all related and is why the engine safety warning light keeps coming on. Also to note--vehicle sways back and forth over small bumps, like riding a small boat in rough water.
Engine check light comes on, and vehicle will lose all power. Contacted dealer. They replaced many parts, but could not solve problem. Problem kept reoccurring.
