The engine power cuts of randomly while driving with no warning at all. When it happens the steering locks up veering the vehicle to the left so you have no control and at the same time the power brakes lock up and you are unable to stop the vehicle. Everything else works when this happens lights, radio, heater, air conditioning. No warning lights display. I had the vehicle with a mechanic that kept it for over 4 months to test drive and see if it would occur. It happened while he drove it but no codes show up to determine the cause. I had it towed back to my home and contacted Jeep Chrysler and they gave me a claim number to bring to my local Jeep dealer. They had it for over a week and unfortunately the jeep ran fine so once again no resolution to be able to fix. I bought the Jeep from Carvana 9/7/24 and am still paying it off but yet haven't been able to drive it for the past 15 months because it is unsafe for myself and anyone else on the roadway.

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.

Vehicle has two open unrepaired recalls: T59 (the federal safety agency 17V‑572, brake booster water shield) and V62 (the federal safety agency 19V‑813, fuel pump relay). The brake booster is currently symptomatic — an audible humming noise is present when the vehicle is stopped and idling, consistent with vacuum loss in the brake booster system. I contacted LaFontaine Chrysler Dodge Jeep Ram of Fenton, Michigan to schedule the recall repairs. An appointment was set for 8:15 AM on April 24, 2026. I requested a loaner or rental vehicle as the dealer indicated they would need to keep the vehicle over the weekend for the work. The dealer never followed up regarding the rental. Instead, the dealer contacted me to appraise my current vehicle and discuss new vehicle inventory. The recall work was never discussed. When I did not appear for the appointment, the dealer did not follow up or offer to reschedule. I then contacted Stellantis customer service directly and explained the situation, including the active brake booster symptom. The Stellantis representative connected me with a second dealership, Bill Snethkamp Chrysler Dodge Jeep Ram on Woodward Avenue in Detroit, Michigan, then disconnected from the call without notice. I was left explaining the situation a second time to a dealership that informed me they do not provide loaner vehicles. The rental option requires me to pay out of pocket upfront and then seek reimbursement from the manufacturer in the form of a check. This is not a viable option. Additionally, this dealership is located approximately one hour from my residence in Flint, making it logistically impractical for recall service. I am currently driving a vehicle with an active safety defect affecting the braking system. The recall remedy language states that limited braking ability can cause a crash without prior warning. Neither the manufacturer nor two dealerships have provided adequate accommodation to complete the recall repair while ensuring I have safe transportation during the service per

While driving the engine power randomly cuts off & steering & brakes lock up veering the vehicle to the left which causes me to have no control of my vehicle. Everything else stays on radio...lights...etc. There is absolutely no warning at all when this occurs. This has happened to me 3 times while driving almost causing me to crash. I brought it to a local Jeep dealer & they couldn't find any codes showing what the issue was. So in fear of getting into a crash that could possibly injure myself or others on the road I haven't been able to drive it safely.

In 2018 the brake booster was tested (vacuum test), and was deemed fine, even though the part itself was placed incorrectly per the recall and could fail at any point. It was not replaced, and marked the recall as closed. Last week the part, brake booster, failed while driving. Jeep is not willing replace due to recall being closed in 2018 and overall recall closed in March 2022.
