2012 Jeep Grand Cherokee problems

UNKNOWN OR OTHER

Problem was Oil Filter housing made of plastic. It was cracked and no warning light that oil had leaked out. Car SUDDENLY DECELERATED as I was merging into traffic on freeway causing vehicles coming up behind to brake rapidly including a semi truck which had been 200 yards back. I rolled onto shoulder with warning lights activated. Pure luck it was not a major accident. Had it fixed at local mechanic in area and was told it is common problem on several makes of vehicles. Mechanic replaced with aluminum one. Gave me a reduced price of $1200.

I was caught driving in a hailstorm when hail impacted and broke the panoramic sunroof of my vehicle. I understand that hail can break automotive glass and that the sunroof is constructed from safety glass. My concern is not that the glass broke, but how it shattered. When the sunroof failed, it fragmented into extremely fine particles and powdered glass. The glass was so fine that it became embedded in the vehicle's seats and interior surfaces. It was in my hair and clothing. Fortunately, the interior cloth sunshade was partially closed at the time and contained much of the debris. Had the shade been open, the glass particles would have fallen directly into the cabin while I was driving. My concern is that the shattered glass created a large volume of fine particulate debris that could have been dispersed throughout the cabin and potentially into occupants' eyes, skin, and airways. This is particularly concerning when considering the possibility of children or other passengers seated beneath the sunroof at the time of failure. Given how fine the resulting particles were, I question whether additional protective measures, such as a laminated layer or other containment system, should be required to prevent shattered glass from entering the passenger compartment when a panoramic sunroof fails. I believe this issue warrants review because the manner in which the glass disintegrated may present a safety risk beyond the initial breakage itself.

STEERING

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 NHTSA '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

SERVICE BRAKES

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 (NHTSA 17V-572, brake booster water shield) and V62 (NHTSA 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

UNKNOWN OR OTHER

The dashboard has warped and lifted significantly from the underlying structure, particularly near the defroster vents and windshield area. The deformation appears to be caused by failure of the internal adhesive or mounting system used to secure the dashboard. The vehicle has only approximately 55,000 miles, and the issue does not appear to be due to normal wear or misuse. The vehicle and dashboard are available for inspection upon request. The warped dashboard creates potential safety concerns related to the passenger-side airbag deployment area, as the deformation occurs near the airbag seam and mounting points. A compromised dashboard structure could potentially interfere with proper airbag deployment in the event of a crash. In addition, the raised and distorted panel can cause glare or visual distraction while driving, which could affect driver visibility and concentration.

ELECTRICAL SYSTEM

I brought my vehicle to the Jeep of concord for a fuel pump relay recall and oil change on 11/12/25. Prior to 11/12 the vehicle did not experience any of the issues described below. On 11/13/25, a dealership representative sent an inspection video stating the vehicle was in immaculate condition following the recall repair. However, within less than 24 hours, the check engine light illuminated, and additional issues began occurring intermittently. After the recall work, the vehicle began experiencing intermittent warning lights, including service four wheel drive, traction control, and check engine. These warnings appear unpredictably and are sometimes accompanied by loss of vehicle functions, creating unsafe driving conditions. The vehicle has also experienced overheating since these issues began. Sometimes turning the vehicle off and then on would temporarily correct the problem if it would recrank. The failures occur intermittently, making them difficult to reproduce or diagnose, and they pose serious safety risks, including the potential for sudden loss of power, steering assistance, or drivability while the vehicle is in motion. On multiple occasions, the issues have left me stranded. I returned the vehicle to the dealership on 1/8/26. On 1/9/26, I received an inspection video from the dealership identifying a transmission issue for the first time. The rep stated they “double-checked” the recall wiring but confirmed that no manufacturer engineer inspected the vehicle, despite my request to escalate this as a STAR case due to safety concerns. The intermittent warning lights, overheating, and transmission concerns remain unresolved and Stellantis refused to escalate the issue. The dealership currently retains possession of my vehicle. I am concerned the recall repair may have been performed wrong or inadequately inspected, resulting in ongoing intermittent safety-related failures affecting multiple vehicle systems. I am requesting that NHTSA investigate & confirm
