I was leaving work and made a right turn. The vehicle steering and breaks locked up and I hit a telephone pole. No warning lights illuminated. The vehicle did not stall. Serious injury could have occurred. Police report and involvement happened as it was a large accident.
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. …
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. …
While driving down a main road, the power steering went out, the brakes locked up, and the accelerator locked up. I had to put the car in park and then turn it off and back on. Yes, it is available for inspection. My safety was put at risk because since my brakes were not working, it means my brake lights also were not, meaning someone would not have seen me stopping and I could have been rear-ended. Others were put at risk because my car could have hit someone else. This has happened 4 other times on different dates and a Jeep dealer has done a fuel pump relay BYPASS twice, but the fuel pump itself was never replaced. There were no warning lamps or messages to warn me about the problem before it failed. I am terrified to drive my own car. This needs to be addressed asap.
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.
The engine / power cuts off with no warning causing steering to lock up to left & brakes lock up causing the vehicle to veer to the left and unable to use brake to stop vehicle. Happens randomly while driving which makes it unsafe to operate to drive.
