My 1998 Wrangler instruments started shutting off by themselves at two years. They are doing it again at four years. The problem is the connectors (plugs) behind the tachometer and speedometer. Take the plastic and steel panels off below the steering wheel and using a flashlight, reach up and make sure those two connectors are tight. Hopefully this will work for two more years. My catalytic converter was just replaced and is already making noises again. The inside comes loose and rattles around. If it breaks and turns sideways it could shut off your engine and damage your rods, so get it fixed.
Talking Catalytic converters - Just had a great experience - bought a 1997 jeep wrangler, and went to local jeep dealer with "the rattle noise" - Jeep dealer said it was a bad converter, and replaced it at $0.00 under 80K miles EPA warranty - no hassle - no attempt at extra charges, although I would have understood a recommended replacement of total exhaust system - my mileage at the time 79,995 miles.
I cannot say anything good about my experience with Jeep. I own a 98 Jeep TJ and purchased it new. I love the vehicle, but recently started hearing a rattling sound coming from the catalytic converter. I contacted Jeep about the defect and they told me that they could not replace the catalytic converter over a rattle. My vehicle is only 4 years old and has only 56K kilometres on it (roughly 35K miles). The warranty on the catalytic converter is good for 8 years or 130K kilometres. The rattle is getting worse, which to me, is a good indicator that the catalytic converter is defective. What I don't understand is why Jeep will not repair what is obviously a well documented defect in a otherwise excellent vehicle. I guess this just goes to show that "Jeep" is not willing to live up to their promise to provide " A satisfactory ownership experience."
I beg to differ, the pre-1997 Wranglers were a far superior AMC design.
Chrysler has done nothing, but screw-up a great vehicle.
