Oil Filter Housing/Oil Cooler Failure Causing Oil and Coolant Contamination, Serpentine Belt Failure, and Engine Overheating My 2021 Jeep Grand Cherokee Laredo E, equipped with the 3.6L Pentastar V6 engine, has developed a significant oil leak originating from the oil filter housing/oil cooler assembly. A mechanic has identified this assembly as the source of the oil leak and confirmed that its failure is allowing engine oil to mix with the coolant. In addition to internal oil and coolant contamination, engine oil is leaking externally onto surrounding engine components, potentially including the serpentine belt and pulley system. The vehicle recently experienced a complete serpentine belt failure while driving, resulting in engine overheating and requiring me to pull over immediately to prevent additional engine damage. I am concerned that oil leaking from the housing assembly may have contributed to the premature deterioration and failure of the serpentine belt. The oil contamination of the cooling system presents additional safety concerns, including reduced cooling efficiency, damage to cooling system components, and the possibility of severe engine damage or unexpected vehicle disablement. The combined risks of external oil leakage, internal coolant contamination, serpentine belt failure, and engine overheating create a potentially dangerous situation, particularly during highway driving. I am concerned that the oil filter housing/oil cooler assembly may have an underlying design or manufacturing defect. I am requesting that NHTSA investigate this issue in 2021 Jeep Grand Cherokee vehicles equipped with the 3.6L Pentastar engine and determine whether a safety recall or other corrective action is warranted.

Suspected Right-Rear Brake Caliper Failure Resulting in Sudden Vehicle Stop Vehicle: 2021 Jeep Grand Cherokee Overland 4x4 Incident date: [XXX] Location: Honolulu, Hawaii Approximate mileage: 64,000 miles Affected component: Right-rear brake caliper assembly On [XXX], while traveling approximately 5 mph, my 2021 Jeep Grand Cherokee experienced a sudden, violent mechanical jolt. The vehicle abruptly stopped, jerking forward and backward with substantial force. When I attempted to accelerate again, the vehicle felt physically restrained, as though something was preventing the wheel from rotating. The vehicle would not drive forward normally, and the AutoPark system engaged under certain conditions. After exiting the vehicle, I discovered a large bolt marked with an “M” lying in the roadway. I initially did not realize it belonged to my vehicle. The responding tow truck operator later identified the bolt as associated with the right-rear brake assembly. During his inspection, the tow truck operator discovered that the right-rear brake caliper was displaced and movable near the wheel. He repositioned the assembly sufficiently to facilitate towing the vehicle to Cutter Jeep in Pearl City, Hawaii. The vehicle’s front and rear brake pads and rotors had previously been replaced on [XXX], at Wolfchase Chrysler Dodge Jeep Ram in Tennessee using genuine Mopar parts. The vehicle had approximately 50,006 miles at that service. The dealership confirmed a two-year parts warranty in writing. The vehicle also underwent routine maintenance at Cutter Jeep on June 26, 2026. I am extremely concerned that this mechanical failure caused my vehicle to stop abruptly at very low speed. Had the same failure occurred while traveling at highway speed, it could potentially have resulted in a serious loss-of-control collision. I am requesting that NHTSA evaluate this incident as a potential vehicle safety defect involving the right-rear brake caliper mounti INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving 65 MPH on a highway in high traffic and the Fuel propulsion system failed without any lights or warning. It just stop responding to accerlation. It was extremely dangerous and CDOT had to come rescue us. We are lucky we were not hurt or killed. The 2021 Jeep Grand Cherokee is only 5 years old and has 46,000 miles on it. The fuel pump needs a complete replacement. It is months out of warranty but still there should be 50,000-100,000 miles left on this part.

Vehicle: 2021 Jeep Grand Cherokee Overland, 3.6L V6 Incident Date: [XXX] Location: [XXX] Safety Complaint: On [XXX], while driving my 2021 Jeep Grand Cherokee Overland on [XXX], the vehicle suddenly lost accelerator response while traveling on the highway. The engine initially remained running, but pressing the accelerator pedal produced no response. Multiple warning indicators illuminated simultaneously, including the electronic throttle control, ABS, traction control, airbag, and four-wheel-drive systems. The vehicle also exhibited unusual electrical behavior, including unexpected activation of the high-beam headlights. The vehicle subsequently became completely inoperable and would no longer crank or start. The sudden loss of propulsion while traveling in highway traffic created a serious safety hazard and placed me at risk of a collision. This incident follows an extensive history of significant mechanical failures and repairs to this vehicle, including: Replacement of the cylinder head following repeated overheating and engine misfires. Complete transmission replacement following transmission-related failures. Replacement of the radiator and cooling fan assembly TWICE within approximately one year, most recently during a trip to North Carolina. Additional mechanical concerns, including a camshaft-related diagnostic trouble code. Despite these major component replacements, the vehicle continues to experience serious reliability and operational failures. These repeated problems have occurred despite attempts to address them through dealership repairs and manufacturer warranty assistance. Stellantis previously extended the vehicle's warranty as a goodwill gesture following earlier issues. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The driver’s seatbelt sensor constantly goes off as not detecting that the seatbelt is buckled, while driving; this causes the alarm to continuously beep and also disables the airbag. Aside from the seatbelt issue, there is a standalone airbag issue that has been detected by the car’s health report multiple times. The drive shaft is also defective, causing the car to shake when the car hits 73 mph. The auto stop/start also disables on its own. I have taken it to the dealership to get all of this fixed but all issues have persisted. There are active recalls on these issues for other 2021 Jeep Grand Cherokees but they are not attached to my vehicle even though my vehicle has the same recall issues.

My 2021 Jeep Grand Cherokee Summit with approximately 39,000 miles. The leather dashboard is delaminating and separating from the substrate. My Jeep dealer has inspected it and checked my VIN. They confirmed that Jeep previously provided extended coverage for essentially this type of dashboard delamination on 2011–2014 Grand Cherokees, but my VIN isn’t included. The vehicle is only slightly beyond the 36,000-mile basic warranty, and I don’t believe a premium leather dashboard should be delaminating at this age and mileage.

The contact owns a 2021 Jeep Grand Cherokee. The contact stated that while driving at an undisclosed speed, there was large puff of smoke coming from the driver's side of the vehicle while coming to a stop. The contact became aware of a brake fluid leak, causing a complete loss of brake pressure and braking power. The brake fluid was leaking more when the brake pedal was depressed. The vehicle was towed to a local independent mechanic and the technicians discovered that the catalytic converter was melted, causing severe heat damage to the adjacent brake lines. The contact stated no other parts were damaged. The vehicle was towed to a dealer; however, the technicians were unable to duplicate the original failure. The dealer was unable to determine what caused the catalytic converter to collapse onto the heat shield near the brake lines. The contact stated that the dealer offered to repair the vehicle by rerouting the brake lines. The manufacturer was notified of the failure. The failure mileage was 46,116.
