Engine stalls without warning causing full loss of power, including power steering and ability to brake properly... ends in engine failure as well. This has resulted in MULTIPLE CLOSE ENCOUNTERS AND LATELY IT CAUSED ME TO HIT THE CURB AND DAMAGED FRONT RIGHT WHEEL.. WILL IT BE ANOTHER CAR AND A CRASH NEXT TIME!???
In August 2025 my 2012 Jeep Grand Cherokee Laredo lost engine power and stalled while driving 15 mph. There was no warning. I was able to restart the car and drive. Then while driving in traffic at 45 mph on 18 Oct 2025, my Jeep abruptly lost engine power and stopped, putting my safety and the safety of my passenger at great risk as I had several cars behind me. Again, the Jeep stalled without warning. I was able to put my emergency warning lights on, then after 30 seconds, I put the car in park and restarted the engine with no problem. The Jeep drove normally. This unexpected loss of power while driving at speed in traffic on Hwy 431 could have been catastrophic. This incident appears to be linked to two previous Fuel Pump Relay recalls, the most recent being V62/NHTSA 19V-813. …
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. …
My vehicle will not start from time to time. At times, when it starts, it quickly shuts off and does not run. I am nervous that my vehicle could crash or be harmful to my family or others. My vehicle is currently unreliable at this time as I am unable to get the recall fuel pump relay part at any nearby dealership as there is a waiting list and they can only order one part every 7-10 days. These series of events have been happening for the past 6 months. Our records indicate that your vehicle [1] was included in previous Safety Recall P54 (NHTSA 14V-530) or Safety Recall R09 (NHTSA 15V-115). The remedy for the previous recalls was to replace the fuel pump relay. If you had either of these recalls completed, the installed remedy relay is susceptible to silicon contamination on the relay contacts, which can cause the relay to fail. …
