Car has 30,000 miles, has not been "off road" or misused. Problem(s) started at about 27,000. . Intermittently while driving, instrument panel and radio lose power. If motor is stopped and restarted, power comes on again. *ak 2. Intermittently, headlights go out when signaling for a right or left turn, then turn on again when turn signal is off. 3. Air conditioner intermittently failed to cool associated with an electrical smell before finally failing to cool altogether. 4. Check engine light and airbag light intermittently go on and off. No consequences to date other than the stress of having an undependable and hot vehicle in miami. Mechanics unable to find the problem with the instrument panel. I am told that I need a new air conditioner but cannot afford to replace it at this time.

Apparently jeep wranglers are known for this problem, yet there has never been a recall. For several months now my dash cluster has been malfunctioning. The RPM guage and speedometer both drop to zero, the airbag and check engine lights come on, and the digital odometer loses its readout and instead says "no bus". It happens sporadically, not continuously. I took it to an independent auto shop which was able to correct the problem, but it began again after a couple months. I just took it to my local jeep dealer for this problem, as well as other electrical problems. (my jeep wouldn't start for the last 3 days.) they found a wire that was corroded and replaced or repaired it. My jeep runs again, but on the way home from the dealership the dash cluster went haywire again. Everyone I have spoken to in the auto shops is aware that this is a common problem with jeeps, including my jeep dealer, but nobody has taken steps to remedy this problem. To date, I have spent nearly $1,300.00 to fix the dash cluster and other electrical problems (probably all related) and my car only has 43,000 miles on it. Conveniently, my manufacturer's warranty expired at 36,000 miles. This began at around 38,000 miles.

Heard loud noises coming from the engine. Check engine light came on. The manifold was cracked in two places. The area dealers happen to have the newly designed manifold in stock due to the problems with the manifold cracking. Have spoken with several people and the same problem occurred with them. This should definitely be recalled. The new manifold has springs built in to make room for give -- the old one did not, therefore causing them to crack. It is very unsafe and costs a lot to get it fixed.

Beginning in 4-99, we have had numerous things go wrong with our new vehicle. First the "check engine" light came on, AC/heater quit/ manfold/exhaust leak/ now all the gauges have gone crazy on the dash & I just got it out of the shop on 1/17/2000, for the very same thing.

The check engine light keeps coming on. I have returned it for service 4 times, and need to bring it back in again. First they said it was a solenoid. Then they traced all of the wiring. The time after that they replaced the module. Next they replaced all of the spark plugs (recall service). They replaced the spark plugs 2-3 weeks ago, and the check engine light is already back on. The dealership's service has been good, but they nor chrysler seem to know why this is occurring.
