The anti collision avoidance systems did not engage. Instead it seemed the vehicle sped up. It did not engage to stop a collision, I was at almost a stop. Vehicle seemed to speed up. Anti-collision systems did not engage at all. This system worked previously. It did not brake automatically nor avoid a collision. It caused an accident & there were minor injuries & totaling 2 vehicles mine (2014 Jeep Grand Cherokee overland) & the other party to accidents truck.

A message comes through the dash screen saying def service 50 miles left vehicle not restart again , I take it to dough smith Jeep dealer in spanish fork for diagnostic they told me to replace a lot of things like def pump, def injector and nox sensor (bank 1) we do and we didn’t solve the problem after spending thousands of dollars and im not able to get my emissions ready because of that , automatic brake system failure it says to clean the sensor I cleaned really good but keep showing brake failure message.

I've been experiencing an issue with the brakes on the vehicle not operating properly since 2022. The vehicle does not brake normally, and the brake pedal must be pressed completely down to the floor, or pumped repeatedly before the vehicle begins to slow, and when it does slow, the brakes are less than responsive. There have been several instances where despite allowing extra stopping distance and pressing the brakes all the way to the floor, the vehicle does not stop normally, and I've come dangerously close to being involved in a collision as a result. I've reported these issues to Jeep in the past when the vehicle was there for service, but it was not adequately evaluated. I replaced both front and rear brake pads and rotors, only to have the issue continue. On 6/27/23 when my vehicle was in the body shop for unrelated repairs, the body shop conducted a brake diagnosis and confirmed the stiff break pedal when attempting to brake. They verified the appropriate vacuum at brake booster and vacuum sensor, and disconnected the brake booster sensor and smoke tested the brake booster to find smoke leaking into the main cabin area. They recommended replacing the brake booster assembly with water shed per TSB, and re-checking. They noted that the vacuum brake booster has failed, and TSB is available in regards to installing water shield with new brake booster, under safety recall t59/NHTSA 17v-572. Once body work was completed, we took the vehicle to perkins Jeep for the open recalls and requested repair of the brake booster, but were told this isn't a Jeep problem, and that it should have been taken care of at the body shop under insurance-- even though this brake issue was pre-existing to the body damage to the vehicle. Jeep states they do not have the oem parts to repair this issue and other open recalls at this time, and there is a waiting list.

I was driving along & all of a sudden my car under side make a funny sound and stopped moving forward. I am a single mother & I had my 4 year old son with me. I had to call a tow company & they took it to a repair shop. They charged me $100 to tell me the transmission was gone & metal pieces were in the transmission. Now I have tried to get it fixed because the rest of my car looks new. I really take care of it. But now I am told it cannot be fixed because you knew there was something wrong with this particular transmission so you no longer make the parts, so no one else can get hurt. Therefore, I have a very lovely car that I love but it will never run again. I spent over $20,000 for my car. Can you help me please.
