On June 24, 2016, between 1:30 pm and 2 pm, I was driving from brentwood ca to vallejo ca on hwy 780 w and after turning a curve on the freeway which sloped down towards curtola parkway, I applied the brakes at about 30 miles per hour after I emerged from the overpass which was at least 5 car lengths before the cars ahead of me which was stopped at a red traffic light. However, the Jeep continued to roll even though I pressed on the brakes to the floor board. When I realized the Jeep did not stop, after checking for vehicles on the left from the rear view mirror, I swerved to the left to avoid hitting the truck in front of me, but I still hit the left corner of the Nissan truck in front of me but the truck did not hit the vehicle in front of him. I damaged the right corner of the front of my Jeep. …
I purchased my Jeep gr Cherokee summit oct 23rd 2018 and it has had suspension problems since I got it. It make a horrible grinding noise when I either turn on or shut off the vehicle and it lasts for a few seconds. I was driving on the highway and service suspension immediately flashed on my dashboard and while driving on the parkway doing 75 miles an hours my car decided to start making a horrible noise like I was driving on the wake up strip on the side of the road and my little idiot light on the dash was flashing the little Jeep icon and it was trying to adjust the height at that rate of speed. For an over $60,000. Dollar truck, I expect more from it then to start to fail after picking it up from the dealer brand new. …
We were driving in the express highway pr 30, at a speed of 45 to 50 MPH, in the direction of humacao towards caguas, we heard a loud noise at the back part of the vehicle (sound it as an impact). The vehicle started making a loud noise. We were able to control the vehicle and park in the area of stops for emergencies. When we inspect the vehicle we noticed that all the rear suspension was on the differential and the escape (muffle). The two structural supports on both sides of the rear suspension were broken. We called a crane and when we got to the flat bed we could see that the chassis had split on both sides of the vehicle. The structural basis of the crossmember in the chassis were broken. The force was so great that the crossmember broke the differential and the muffler. …

Vehicle has said service air suspension numerous times. Took to the dealer several times and the mechanic cant find anything wrong or replicate the issue. Now car is stuck with the front suspension all the way at the bottom and the back is stuck in a higher position. Hear air compressions in the back of the car, air suspension is trying to activate but wont move. Is able to drive at various speed. Attempted to raise and lower at park, neutral and moving at various speeds from 5-60mph. Was warned to not drive unless needed to because vehicle could lose control easily. Is up to date on recalls and service reports. Seems like a big safety issue
While driving on the highway the Jeep jolted/ jumped to the side when we drove over mildly unevenly paved roads or overpasses causing us to lose control of our vehicle momentarily. We were at 65 MPH and the Jeep rocked a few times upon attempting to stabilize. This has happened numerous times and our last incident almost threw us into the side of a semi. The dealer cannot explain this and we have had new tires and an alignment done without any improvement. If we keep this car I know beyond a doubt that this situation will be the cause of a serious accident / fatality. There is 70,000 miles on this Jeep.
