It got 7 problem issues and almost lost control due to electronic throttle control failed while drove on freeway and tow teardrop (1400 lbs). Malfunction indicator light, traction on (could not turn off), electronic stability control active popped up ( could not turn off), service forward collision warning light, cruise control fault warning light, service stop/start system warning light, service adaptive cruise control warniing light (all of them popped up that could not turn off). I went to jim click Jeep dealership and they never seen them before. I am very disappointed and I feel that my truck is "lemon" I told them to fix asap but they can not fix and have to wait till August 9 (appointment) to check whats wrong.

Under heavy breaking the rear wheels of my vehicle lifted off of the pavement. This loss of traction and shift in weight resulted in a head on collision with a vehicle in the opposite lane of traffic. After the accident I discover that the suspension for my vehicle was incorrect to the level that FCA released a TSB regarding the issue. The suspension that was equipped with the vehicle was designed for the gasoline motor and the weight associated with that motor. My vehicle has the diesel motor (approximately 600lbs heavier) along with factory equipped steel bumpers adding additional weight. This factory design failure created a vehicle that could not perform as designed and as I found out via an automotive accident, a vehicle that under heavy breaking can lift its rear wheels off of the ground.

The vehicle suddenly accelerates. The rpm-??s shoot up real high, the Jeep accelerates and the brakes do NOT work. This has occurred while driving at 55-60 mph and twice driving in city traffic going approx. 30-35. The acceleration increases and is stuck. I press the brakes and they do not work until whatever is sticking releases.

On 3 different occasions the acceleration got stuck and increased speed. I pressed the brake over and over and the Jeep would NOT reduce speed or slow down for what ranged between 30 - 45 seconds. Had there been a vehicle directly in front of me I would have slammed into the vehicle. If I had been trying to stop at an intersection I would not have been able to stop. I had my child in the car two out of the three times this has occurred. The dealership states that they have not had any complaints of this occurring and could not replicate it during the few minutes they drove it and do not seem to be concerned that this issue could seriously injure or kill me, my child, or others. This is a SERIOUS issue that should be addressed immediately.

problem #28

Gladiator

  • miles
I was driving the vehicle, while towing a 5000lb trailer (vehicle tow rating is 6000lb), up a 4-5% grade at 4000'-6000' elevation, with ambient temperature around 80 degrees, and the vehicle unexpectedly derated / limited speed to approx 45 mph with no warning indicators on the vehicle. I had a number of cars and semi trucks behind me, and so I unexpectedly needed to find a safe place to pull over, which was limited due to the road conditions. I travel in areas frequented by semi trucks with limited shoulders. If I had not found a pull-out, this could have been dangerous. This appears to be an issue countered by a number of Jeep Gladiator Diesel owners, relating to either engine oil temperature too high, or EGT temp too high when towing uphill.
