Four problems related to cruise control have been reported for the 1998 Jeep Wrangler. The most recently reported issues are listed below.
While using cruise control speed increased and would not respond to shutting off speed control or by hitting the brakes car could not be stopped only pushing in clutch while the engine raced uncontrollably and pulling off the interstate onto side of road turning off key stopped this . When started back up engine still racing. Same thing happened about seven years ago never used speed control again until this.
1. The transmission has started jumping in and out of 3rd gear in the 32 to 50 mph range. Bubbles are present in the fluid indicating a seal is failing. Repair estimate at this time is over $1000. This failure in snowy driving conditions causes vehicle control problems. 2. Passenger seat belt retracts intermittently. The passenger will lean forward and back may not notice the seatbelt has not retracted. This can certainly cause serious injury or death in the event of an accident. 3. Sudden acceleration at idle. Vehicle idle will jump from 1. 5k to 3k without warning. Obviously a serious safety hazard. 4. Anti-sway bar link failure. This is perhaps the most insidious failure. The stabilizer bar link ball will corrode in the socket and cause it to separate. The rubber boot around it covers the failure. When an emergency turn is required, the Jeep will sway violently. I talked to the Chrysler parts attendant and he said he sells about 12 a week to those lucky enough to notice the failure. For those who do not notice this, it is a time bomb. The parts attendant told me I would be back soon to replace more. What he said is true.
Defective electrical connector caused all the gauges to fail and air bags to shut down.
