Dashboard lights and alarms simultaneously blink on and off. Seems to be a short circuit in the wiring. Gas tank levels off at "empty", and the fuel gauge spins 180 degrees so that it is caught under the "resting stick" at 0, therefore, no longer reading the gauge. This happens while in motion and while parked.
Jeep Grand Cherokee has defective tail/brake lights. Mine have been replaced on several occasions and now its out again. I know other people who have the same vehicle and are having the same problems.
About every year the taillight/brake light sockets corrode and the lights quit functioning. Cleaning them solves the problem. We live in phoenix area and so moisture is not a factor.
Over the past 6 months at random the brake lights seem to burn out. It might be the left side one week and the right the next. New bulbs often last between 1 hour and 3 weeks. The local dealership tells me that electrical wiring problems are often very hard to fix.
Main engine wiring harness insulation melted at the connectors to the fuel injectors causing multiple fuel injector misfires. The problem can be corrected with new connectors to the injectors however Chrysler corp. Only sells the entire harness at a cost of $1800. 00.
After the car was driven for less than 15 minutes from work to home, we heard a loud explosion like sound from the car 10-15 minutes after the car had been parked. Engine was off at the time and key was not in the ignition device at time of fire.
I own a Jeep Grand Cherokee VIN # 1j4gw58n3yc117263 milage 57000 mile the heater went out I was told that it was a wiring harnesss the cost was over $500. 00 they told me at the dealer that they have seen this many times. I asked if there was a recall on this they said not at this time. This is a safety hazard it left me with no defrosters. I also have a concern that it could be a fire hazard if infact the wireing harness was burned up!.
Consumer stated the parking lights on the right side were not working, the dealer found a wire loose for the right side parking light going into the junction block.
