2021 Jeep Gladiator Complaints

  • Power Train 08/24/2026

    Component Affected: Power Train / Automatic Transmission (850RE 8-Speed)Description of Safety Hazard:While driving my 2022 Jeep Gladiator (53,940 miles), the transmission experienced a severe internal component failure, specifically throwing error code P0733-00 (Gear 3 Shift Incorrect Ratio). This causes the transmission to violently slip, shift harshly, or completely fail to engage 3rd gear while accelerating.This creates an immediate and severe safety hazard on public roads. When the transmission fails to engage the gear, the vehicle experiences a sudden, uncommanded loss of motive power while in traffic. This leaves the vehicle coasting without acceleration, exposing myself and my passengers to an extremely high risk of being rear-ended by oncoming traffic.This issue is a known manufacturing defect involving the internal transmission "D" Clutch assembly, as documented in manufacturer Technical Service Bulletin TSB 21-009-25. The dealership refused to properly pull the historical cod...

  • Vehicle Speed Control, unknown Or Other, fuel/propulsion System 08/04/2026

    Truck failed to find gear shuddered lost speed in traffic while going up a hill. Limp mode was initiated. This is a known manufacturers defect with a tsb applied against the known issue. Issue is widespread when researched but not made known by the manufacturer of the truck. Dealership refusing repair under goodwill due to truck being out of mileage by 5000miles.

Repeat this is a known defect that is being ignored by manufacturer.

  • Service Brakes 07/10/2026

    Front brake caliper(s) was seizing up causing smoking and a burning smell. Vehicle was also pulling to the right when braking. Brake fluid or something like it coated the front drivers side wheel. Took vehicle back to dealership where vehicle was purchased new. Vehicle is still under warranty/extended warranties. The dealer did inspect and found front calipers to be seizing up causing excessive wear on brake pads and rotors. They did replace both front calipers but not the brake hoses. They also replaced and charged me for new brake pads and rotors. Not even a week later, I called the dealer to report the same problem, the brakes were again seizing up and there was a smoking/burning smell. The dealer ordered the new brake hoses, found that the brake hoses they attempted to re-use had collapsed causing all the above mentioned problems. The dealer had them installed and so far so good.

  • Steering, suspension 07/26/2026

    I am experiencing the "Jeep Death Wobble" which occurs intermittently after hitting any road imperfections i.e. uneven road surface connections, potholes, or rumble strips, causing a violent and sudden shaking of the steering wheel at highway speeds. I feel like the wheels are going to fall off it shakes so bad!!! I either have to slow down to under 45 mph or less, or come to a complete stop in order for it to stop wobbling. This does not happen on smooth road surfaces. I have a stock 2021 Jeep Gladiator which I bought brand new the end of 2020. Whenever this happens, I need to get off the road if there are people behind me as I need to slow my speed and or exit the roadway. This puts me at risk especially when traveling interstate highways with tractor trailers and other large vehicles behind me. I advised the dealership in the past that I was experiencing this problem and they were supposed to order a stabilizer for my jeep but have never heard back about it. My Jeep is av...
