Transmission 2

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 codes or address the issue, leaving a dangerous, defect-plagued vehicle on the road. Stellantis / Jeep needs to issue a mandatory safety recall for this 850RE transmission D-clutch defect before this sudden loss of acceleration causes a fatal accident

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. Symptoms started prior to exiting warranty but due to no communication by dealership or manufacturer unit was not brought in for repair prior. Repeat this is a known defect that is being ignored by manufacturer.

Brakes 2

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.

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 available for inspection as it has not been fixed. My Jeep was just in for bad calipers/brakes/rotors and had a multi-point inspection on 7/11/26 and 7/22/26. However, the wobble still happens. I am listing below the most recent date that this wobble occurred which was 7/26/26

Transmission 1

2021 Jeep Gladiator Sport S equipped with 6 speed manual transmission purchased from Landers Jeep in Little Rock Ar. Vehicle required the A-19 clutch recall. Recall was completed and I took ownership 6/17/2025. I returned the vehicle within the first week of ownership due to the "service transmission" light periodically coming on. Dealership reset the clutch counter and attempted to give me advice on how to drive a vehicle I was more than capable driving before purchasing. After 13 months and 13k miles I have now gotten a "clutch hot fully release clutch pedal and reduce clutch use" warning twice while traveling down the interstate at 65mph. When this light comes on the vehicle enters "limp mode" and dramatically loses power, not to mention the original recall warnings of fire and fragments. Now clutch is slipping and vehicle power is reduced. Today at a scheduled service appointment to readdress this issue, I was informed by the service manager at Landers that they only fix recalls once and will not readdress the issue.

The vehicle was bought in CA and hasn't had any issues till about after 3-4 yrs later. 1) Adaptive cruise control / emergency braking system / forward collision notification will occassionally state "not availble/unavailable" or "visibility" is not available and to clean windshield, but the windshield is not dirty or obstructing the camera. 2) The fuel emission system has had several diagnostic codes referring to the gas gap or fuel sensors. Vehicle is boggs down/loses power and starts ideling roughly and acts like it wants to shutdown and has shutdown. I've had to get vehicle towed twice for this issue. Replaced gas gap and still had issues. Then they went away for a few months, but now I am getting a diagnotic code stating that the fuel tank gas sensor is causing the check engine light.

Engine oil light came on. Inspected at Tom Obrien Jeep for low oil pressure. Technician found that one of the oil sprayers was not bolted onto block, screw was there and tight, sprayer was in oil pan. It was incorrectly assembled. Jeep would not warranty due to lack of oil change receipts which is irrelevant.

7/5/2026. Driving home on the highway the Jeep went into limp mode and shut down. The Fault flashed on the screen for about 15 seconds (Throttle Body Falut) Problem is there is no warning when it happens. It just shuts down. This creates a "REALLY SERIOUS HAZZARD" This time it did register a fault on the computer and we were able to pull it off the reader. The Fault reads as follows: POOAF In looking it up on this is a manufacuring problem that can be caused by a little dirt, Can be caused by hot weather. THIS IS NOT SAFE! MY I REPEAT, THIS IS NOT SAFE! This should be recalled and Fixed as I am sure this shutting down on the Hiways and Interstates have killed people that were not able to deal with a situation. Please force a recall befor lives are lost!

I purchased this vehicle on May 25th. On june 4th it was parked out side my front porch and my house along with the jeep burned completely down. the fire was first witnessed on the front porch right where the jeep was parked. I was out of town working and had a friend there dog sitting for me. She and the dogs got out safely althoug she was sent to the hospital for smoke inhalation and was released later that evening. The arson investigation is still on going. as of monday June 8th, Both the arson investigator and home insurnace investigator could not determine the origin of the fire. When the recall went public on june 11th i informed them of the recall and have not gotten much back from either of them. The scene has yet to be re-visted. I drove the truck maybe a total of 150 miles. The steering felt strange at times but i only had the vehicle for 5 days before i left for work. There is no solution from jeep. I would really like for a specialest to inspect the vehicle to determine if it did in fact set my house on fire.

Engine light came on, vehicle went into limp mode. Transmission would not shift any higher than 3rd gear and kept slipping while on interstate! Was almost hit by several 18 wheelers! Jeep dealership said our vin is not part of the service bulletin but they did get the P0733 code! Make it make sense! I guess we’re supposed to get run over by 18 wheelers before they’ll fix it!

Every time I fill up my gas tank, the fuel doesn’t shut off in time from the pump and gas comes backward up the filler neck, onto the side of my jeep.
