2012 Jeep Grand Cherokee: brake failure

Filed Jun 1, 2026 · Brakes · IN

Upon starting my Jeep on the coldest day of the year back in January when I pressed the brake pedal to start it there was a loud and it reminded me, there was a recall out for the break booster pop and the pedal went all the way to the floor. It was fifteen below zero out.So I thought that it blew a brake line. I checked the lines going to all four.Wheels and could not find any fluid. I could not figure out where all the fluid went. I refilled the reservoir with two full cans of brake fluid. Tried pumping the pedal and again it went to the floor. Got out and inspected all lines and the reservoir itself.... Still could not find a leak. I googled the problem and saw a recall for the brake booster. Said it was installed incorrectly and water could enter the booster and master cylinder and freeze if cold outside and cause a serious accident causing serious injury or death. I inspected the system and water had entered the booster and master cylinder and froze. It ruined the master cylinder. I asked the dealership if they would pick up the vehicle and repair it. First they said yes then no they don't pick vehicles up. They ordered only a little shield to fix the booster per the recall but said that's all they would do. Why would I pay $200 out of my pocket to have the vehicle taken to them.Only to have them put a shield on the booster. I still would have no brakes. That is ridiculous. This is supposed to be a major safety issue.And it is! If I had been driving when I pressed on the brake pedal and it went to the floor I could have been killed or other innocent people could have been killed. You the federal safety agency 's answer said Chrysler is contractually. Obligated to not only pick up my vehicle but to repair any and all components of the brake system to return the vehicle to previous safety operation at no charge to me. You also said that I should be given a loaner vehicle to use while mine is repaired. Dealership is refusing. I could be dead and so could other innocent people

The vehicle is a 2012 Jeep Grand Cherokee with open safety recalls T59 and V62. The brake warning light is currently illuminated, and based on the symptoms I believe the brake booster may be failing. The braking system is available for inspection upon request. The safety concern is that the vehicle may have reduced braking assist or impaired braking performance while being driven. This creates a risk of increased stopping distance, loss of braking confidence, or inability to stop safely in traffic. I contacted the FCA/Stellantis-recommended Jeep dealership in Lapeer, Michigan multiple times this week to schedule recall-related service. I was repeatedly transferred to service voicemail and did not receive return calls. When I called back and asked to speak with someone else, I reached the service manager. I explained that the vehicle has an illuminated brake warning light and that I suspect the brake booster may be failing. The service manager focused on where I lived, why I was not using a closer dealer, and mentioned that the vehicle is 14 years old, rather than clearly arranging recall service or addressing the brake safety concern. The problem has not yet been inspected or confirmed by a dealer because I have been unable to obtain timely service despite repeated attempts. The vehicle has not been inspected by the manufacturer, police, insurance representatives, or others. The warning lamp currently present is the brake warning light. The exact first date the warning light appeared was within the last 2 weeks.

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. The jeep is unsafe because the brakes failed and would have caused a fatal accident to me, my three passengers, and other vehicles had I been travelling at a high speed. I complied with all available recall repairs including the brake recall in 2014 and all the suggested chrysler maintenance on the jeep. I reported the accident to my insurance geico and to chrysler.
