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.

“The contact owns a 2021 Jeep Gladiator. The contact stated that two years ago the vehicle was taken to a dealer to be repaired under NHTSA Campaign Number: 23V116000 (Power Train); to prevent the clutch from overheating. However, the failure started after the vehicle was repaired under the recall repair. The contact stated that while driving, there was smoke coming from under the hood. The manufacturer was notified of the failure, and the vehicle was taken to an authorized dealer to be diagnosed; however, the dealer was unable to perform the inspection or confirm the failure due to the age and mileage on the vehicle. The contact stated that the software update included a transmission kill switch to be activated whenever the clutch overheated, but the kill switch failed to operate as intended. The message that the clutch was overheating was displayed on the instrument panel during the failure. There was a burning odor and smoke during the failure. The manufacturer was made aware of the failure. The failure mileage was 26,000.”
