“The contact owns a 2021 Jeep Grand Cherokee. The contact stated that while driving 70 MPH, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended and the vehicle jerked abnormally. The vehicle was taken to the dealer; however, the failure was not duplicated. The failure was a persistent failure. The vehicle was taken to an independent mechanic where it was diagnosed with transmission failure. The contact was informed that there were metal shavings inside the oil pan. The contact was informed that the transmission needed to be replaced. The vehicle was being repaired. The manufacturer was contacted and made aware of the failure.

Fuel/propulsion system

4 reports
“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…”

Air bags

2 reports
“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

2 reports
“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.”

Engine

1 report
“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…”
