ENGINE
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.

SERVICE BRAKES, WHEELS, UNKNOWN OR OTHER
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.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM, POWER TRAIN
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)

FUEL/PROPULSION SYSTEM
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.

AIR BAGS, SEAT BELTS
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.

STRUCTURE:INTERIOR PANELS:DASHBOARD
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.

FUEL/PROPULSION SYSTEM
On [XXX] while driving in northeastern colorado on hevily traveled [XXX] without warnin lamps, messages or other symptoms my vehicle stopped running. I was in a lane of traffic and since car had stalled out I had limited steering, braking etc. I did manage to get my vehicle out of the lane of traffic, however, still close to traffice traveling at high speeds past me.After about 30 very stressful minutes I managed to get law enforcement assistance. We were both still in a dangerous position where often wrecks happen by traffic veering and hitting vehicles on the side of the road. Vehicle was towed to Golden, CO for repair at Jeep and found to be failed fuel pump, which I understand Jeep is known for with recalls on other VIN numbers but my jeep was not included. Basic information that my 2021 Grand Cherokee had only 46, 933 miles on it. I believe this component never should have failed at this mileage. I believe that this year Jeep has had many fuel pump failures as jeep "just happened to have a fuel pump in stock". I also believe that this incident could have turned deadly had I not managed to get somewhat off the highway, especially for law enforcement and me. This year VIN should be included probably along with other in a Recall for the fuel pump. The dealer informed me this was not covered under warranty. Colorado has adopted California emissions however that starts with 2022 models and mine is 2021. Even after contesting this covering repairs was denied. With the hazardous position I was placed in, this definitely created a safety issue, especially if I had not managed to get out of the traffic lane. Having worked in the fire service for 19 years I had knowledge of the number of crashes occurring under these circumstances thus contributing to my stress level at the time.

FUEL/PROPULSION SYSTEM, POWER TRAIN
Electronic Throttle Control warning light comes on upon starting vehicle while extended crank occurs. When starting car, the push to start feature will not turn over and continuously cranks multiple times. Issue is intermittent- never know when it will happen which makes it difficult to replicate at service center. Took car into 2 mechanics on separate occasions and finally to the Jeep dealership for service. Because issue couldn’t be duplicated- nothing was done. However, recently while driving, same extended crank pattern noise and unstable/rough propulsion occurred while driving on the highway. Same Electronic throttle control warning light came on along with the check engine light. Also cruise control and the auto On Off feature became disabled. I scheduled service with my mechanic as soon as possible and they found the stored code was related to Technical Service Bulletin 2014-004-25 REV.B. This bulletin lists the symptoms I described yet the dealership did not perform the fuel pressure Test and Replace Fuel Pressure Regulator. I called the dealership to schedule warranty service for this TBS and they gave me difficulty acknowledging the TSB was issued for my make/model/year and scheduling a service appt. I spent the last few hours reading all of the complaints on NHTSA for 2021 Jeep Grand Cherokee and it is alarming how many of the complaint are for this specific issue. It is dangerous for anyone on the road to be driving in a vehicle you can’t rely on to propel you forward when you press the gas or stall due to faulty fuel pressure regulator amid traffic. An investigation should be done. Furthermore, in reviewing other recalls, I found this is a recurrent issue for Jeep. It appears they’ve been various safety recalls issued for this in the past for vehicles made from 2011-2020. How they haven’t addressed it in new models is appalling. For owners of the vehicle, it’s difficult to have any leverage with dealership since it is not easy to replicate on demand.

EXTERIOR LIGHTING
I was driving back from the airport and as it began to get dark, it became apparent I had no headlights. I somehow managed to drive the last two hours home on parking lights and lights from other vehicles.I took it to a Chrysler Jeep dealership Goldies in Huntington, West Virginia. The exam that I put a bulb in the driver side. In the passenger side, the LED portion is still glowing, but is yellow green and they told me it would require a headline assembly which would call somewhere between 1500 and $2000. The bulb alone was just over $500. They told me that the filaments had cracked in the bulb despite no apparent damage to the vehicle. I owned an accurate T from 2008 to 2021 I and it never required new bulbs. I actually don’t do much nighttime driving so they could not have many hours on the lights. I don’t know what but something is wrong here.

FUEL/PROPULSION SYSTEM
While driving, the vehicle experienced a sudden, unexpected engine stall and complete loss of propulsion due to a premature failure of the in-tank electric fuel pump. This failure occurred at only 37,000 miles, which is well below the expected lifespan of a major fuel system component. A sudden loss of engine power while operating at speed poses an immediate safety hazard, increasing the risk of a rear-end collision or leaving the vehicle stranded in active traffic. The fuel pump had to be replaced immediately to restore the vehicle to a safe operating condition. The original failed component was replaced by an independent repair facility, and all itemized repair orders and proof-of-payment receipts have been retained. I am logging this complaint to urge NHTSA to investigate a potential manufacturing defect in 2021 Jeep Grand Cherokee fuel delivery systems.

ELECTRICAL SYSTEM
I had stopped at a red light and the auto start/stop turned off the car. It would not restart. The fault caused it to stay in Park and could not get out of Park to move vehicle. This not only caused a road hazard but made me and others unsafe. The cause was a enclosed fuse box that made batteries go bad. I feel Jeep should be responsible for this.

WHEELS
To Whom It May Concern: I am writing to formally notify you of a serious and dangerous safety defect involving the vehicle I purchased from Carvana on February 2, 2026. On April 9, 2026, while driving on the highway at 70 MPH, my truck stopped abruptly after experiencing a critical wheel failure. Upon exiting the vehicle, I notice that all the lug nuts were missing. I immediately located a tow driver that confirmed what I observed. The tow company towed the vehicles to a Dodge mechanic in Paducah, KY. Upon inspection by a certified mechanic, I was informed that the wheel failure was caused by either a improperly installed loose or too tightened lug nuts, resulting in damage to the wheel hub and wheel assembly, which condition represents a severe safety hazard that could have resulted in catastrophic injury or death. Prior to the malfunction, there were no warning lamps or messages until the actual event. When purchased, Carvana represented that its vehicles undergo thorough inspections and are safe for operation. However, this incident demonstrates a clear failure in inspection, preparation, or mechanical servicing, including but not limited to: •Failure to ensure lug nuts were properly installed and secured •Failure to identify an obvious and critical safety issue •Delivery of a vehicle that was not roadworthy at the time of sale A wheel detachment risk is not a minor and or normal wear and tear as stated by Carvana's warranty company Silver Rock Warranty and Carvana Warranty support team. The malfunction was a fundamental safety failure that any reasonable inspection would have identified and corrected prior to sale.

The contact owns a 2021 Jeep Grand Cherokee. The contact stated that while driving at various speeds, the vehicle hesitated while depressing the accelerator pedal and attempting to overtake another vehicle. The RPM was extremely elevated; however, the vehicle failed to respond as intended. The contact pulled over to the shoulder of the roadway and restarted the vehicle before resuming normal driving. The contact became aware that, when shifting between automatic and manual driving modes, the vehicle operated normally without hesitating. The vehicle was taken to several dealers on several occasions; however, the dealer was unable to duplicate the failure or determine the cause of the failure. In addition, the headlights occasionally shut off unexpectedly while driving at night. The contact would pull over and wait for the headlights to return before resuming normal driving. The manufacturer was notified of the failure and informed the contact that there were no recalls associated with the VIN for the failure. The vehicle was not repaired. The failure mileage was approximately 50,000.
