2021 Jeep Grand Cherokee Trackhawk problems

“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…”

“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.”

“Final drive control module, transfercase control module went out. Causing “Service 4WD” message Check-engine/MIL light 4WD system becoming unavailable Trouble codes related to the drivetrain control module Intermittent 4WD problems Speed issues”

“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.”

“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…”
