    While slowing to a stop and fully depressing only the brake with my right foot my vehicle rapidly accelerated into the back of another truck. It felt like the front brakes engaged, but the rear wheels continued to accelerate as the vehicle transmission worked to downshift. Serious safety issue-I am 100% confident that I was standing on the brake and not the accelerator. The road was dry with no gravel and I was gradually slowing to a stop when this occurred.

    While at the dealer for a routine oil change, the tech observed fluid on inside of the passenger rear wheel, brake, and rotor. Fluid appears to be axle fluid that is leaking.

    My front suspension keeps bottoming out while driving down the road. If I catch a pothole or dip in the road I will bottom out. Today I was in a parking lot and it bottomed out going over a speed bump. I know there is a TSB for the eco diesel Rubicons but for no other sub-models.

    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.

    Engine oil temperature reached 265 degrees while towing within capacity - engine derated power and I could not drive above 35mph on a road with a speed limit if 75mph. It was dangerous!

    Vehicle derates power when ambient temps are 85* F and up while towing my camp (which is far below the max tow rating) During a couple of these derates I was in areas where the speed limit was 65 and 75 mph, my max obtainable speed was 35mph. I heavy truck traffic i feel that was in danger and a hazard in the road. This vehicle is rated to tow far more than the loads it is actually capable of towing in higher temperatures. I have seen my oil temps rise to 265* F on multiple occasions and it seems this is around the temperature that the vehicle starts to derate. It has been my observation that the cooling system is under sized and in turn puts occupants of the vehicle at risk.
