Open the full vehicle complaint log (all categories)the rear control arm welds have repeatedly broken on this 2020 jeep gladiator which creates a hazardous handling condition that may lead to a tragic accident. the local dealer, Hilltop Jeep in Richmond, CA and Stellantis Customer Service have passed the buck and said it isn't their responsibility and have referred us to a body shop to get the suspension repairs done. this seems like a manufacturing defect.
Death wobble. Excessive wobbling while traveling on the highway. Usually occurs after traveling over variations in the roadway surface. Happened one before when vehicle had approximately 30,000 miles. Dealer replaced the stabilizer. Started again at approximately 60,000 miles. Wobble can get so bad i feel like i’m going to get thrown out of the vehicle.
Multiple issues occuring starting (documented) at 22,719 miles (09/27/2022) - stop/start and remote start had not been functioning properly - vehicle died. Required towing to dealer. Both batteries were dead. Upon leaving dealer they had not reconnected stop/start. Fast forward to 05/04/2024 and vehicle once again unchargeable to start. Took warrantied battery back to dealer and they wanted us to tow it there to check. We spent 350.91 to replace ourselves due to a lack of confidence with Jeep. Then on 05/20/2024 took it to a 4x4 center and discovered multiple issues with vehicle from manufacturing and dealer work. To start -- 1) the rear differential pinion seal is leaking 2) the power stearing box is aluminum and showed signs of flex and contact 3) dealer installed lift was incomplete leaving the front axle off center (visually observed about a 3" offset).

DEATH WOBBLE AND VIBRATION WHEN VEHICLE HOT IN DIFFERENT SURFACES LIKE CROSSING BRIDGE WHEELS AND STEERING UNCONTROLLABLE AT HIGH SPEED OVER 40 MPH. UNUSUAL SMELL INSIDE CABIN. THIS HAPPENS ON HIGHWAY AFTER ABOUT TWO HOURS OF DRIVING.
WHILE TRAVELING AT APPROXIMATELY 70MPH ON THE INTERSTATE AFTER TRAVELING OVER A SMALL BUMP THE STEERING WHEEL SHOOK VIOLENTLY FOR 3 TO 4 SECONDS UNTIL I SLOWED DOWN THE VEHICLE TO APPROXIMATELY 50MPH. A MILE OR SO DOWN THE ROAD THE VEHICLE DID THE SAME THING AT ABOUT THE SAME SPEED
WHILE DRIVING AT ALL SPEEDS ON HIGHWAY AND SIDE ROADS WHILE TRAVELING STRAIGHT THE VEHICLE WANDERS BOTH TO THE LEFT AND THE RIGHT. THERE IS ALSO ALOT OF PLAY IN THE STEERING WHEEL.
A MONTH AFTER PURCHASING MY 2020 JEEP GLADIATOR OVERLAND I NOTICED HOW BOUNCY IT FELT ON THE ROAD AND WHEN TURNING RIGHT I FELT A GRINDING SOUND. THE JEEP HAS SPENT ALL ITS TIME COMMUTING TO AND FROM WORK ON THE HIGHWAY. I TOOK OFF THE RIGHT FRONT TIRE AND I NOTICED THAT THE SHOCK BRACKET THAT IS WELDED TO THE AXLE WAS COMPLETELY BROKEN OFF AND MAKING CONTACT WITH MY TIRE. UPON FURTHER INSPECTION I NOTICED IT WAS ONLY A LITTLE SPOT WELD THAT HELD THAT WHOLE THING TOGETHER. THE BROKEN SHOCK MOUNT WAS DANGLING AND TEARING THE INSIDE OF MY TIRE. I HAD IT TOWED TO THE DEALERSHIP AND THE EXPLANATION I RECEIVED FROM THE SERVICE DEPARTMENT WAS THAT THE ROBOT MISSED A LOT OF WELDS ON THE FRONT AXLE. IT HAS NOW BEEN A MONTH NOW AND MY JEEP IS STILL SITTING AND AWAITING PARTS. NOT MUCH SUPPORT FROM JEEP, JUST MAKING PAYMENTS ON A CAR I CAN'T DRIVE.
