Selected complaints filed with NHTSA by 2020 Jeep Grand Cherokee owners, lightly cleaned up (personal details are redacted by NHTSA).
Driving down the interstate at 75mph, the vehicle all of a sudden lost the ability to accelerate and felt like it shifted into neutral. We were able to pull over to the side of the road safely and as we were getting out of the vehicle, we noticed flames shooting out from under the engine. My wife and I made it out safely and as we got about 100 yards away and looked back toward the vehicle, the entire front part of the vehicle was engulfed in flames. We sat along the side of the interstate and watched the vehicle burn for 20-25 minutes. We just had the vehicle in for service 6 days prior to get a new battery, a new aux battery, an advanced diagnostic, brake fluid exchange, and a fuel system service. The evening we picked up the vehicle from service, we got an email with a powertrain alert indicator. …
The contact owns a 2020 Jeep Grand Cherokee. The contact stated that the air bag and seat belt failure warning lights were illuminated. After filling the fuel tank and attempting to start the vehicle, the vehicle failed to start. The vehicle was towed to the dealer, who diagnosed that the battery and fuse box water pump had failed and were replaced. The failure persisted. The dealer inspected the vehicle again and then diagnosed that the Occupant Restraint Control module had failed and caused the air bag to deploy inadvertently, failed to deploy, and needed to be replaced. The contact became aware of NHTSA Campaign Number: 15V046000 (Air Bags); however, the VIN was not included in the recall. The vehicle was not repaired. The manufacturer was informed of the failure. The manufacturer confirmed the VIN was not included. …
The contact owns a 2020 Jeep Grand Cherokee. The contact stated that the vehicle intermittently failed to start immediately, but started after the second attempt.

While slowly turning into a parking slot in front of a building, the vehicle surged forward, jumping the curb and striking a metal handrail and the corner of the building. Substantial damage resulted to the front, hood and cooling systems.
While driving on the interstate at highway speeds, the vehicle suffered a sudden and complete loss of motive power without warning, causing the engine to stall. The vehicle became a severe safety hazard in active traffic as power steering and power braking assists were greatly reduced, nearly causing a high-speed rear-end collision before I could safely coast to the shoulder.Upon investigation, the vehicle completely ran out of gasoline, despite the dashboard fuel gauge explicitly indicating at least a 1/4 tank of fuel remaining.This is the second time this exact failure has occurred. The first instance happened during the vehicle's factory warranty period. At that time, the dealership misdiagnosed the issue and replaced the auxiliary battery, failing to address the underlying fuel delivery defect.The vehicle currently has 37,950 miles. …
My Jeep is a 2020, and I recently bought it last June as a certified preowned vehicle from a Jeep dealership. I was having electrical and fuse problems when my moon roof on the vehicle stopped working. Recently driving home at night, I lost all lights on the vehicle. Headlight, high beams, brake lights and turn signals, the lights do not work on the vehicle and I was driving in the complete dark. My gas tank also was having issues and it does not allow me to fill the tank because it thinks it is always "full" even though it is not. I brought the vehicle to the dealership and they stayed I have a completely fried computer system as well as the vent tube on my gas tank is "clogged" and the entire gas tank needs to be replaced. I have owned the car for less than a year and a half, it is only three years old and the warranty JUST expired. …
This issue has now happened 3 times. The first time it happened I took it in and they said it was an auxiliary battery that was replaced. The issue is the vehicle will stall and shutoff completely because it is completely out of fuel even though the electronic gauge and the needle show it has gas in it. This Saturday we was driving on the interstate at around 70mph and it showed a little over a 1/4 tank on the needle and 130 miles to empty on the digital readout. It shutoff completely and we were almost hit on the interstate from behind I barely had enough coast to get over to the side of the road. The first time it happened it shutoff and was going much slower and it actually started back up and let me drive. …
My 2020 Jeep will regularly turnover but not start after pushing the start button. As of now, the vehicle will start normal after pushing the start button a second time. Research has shown many people have had and are still having this exact issue. It would seem that most of the ones with this problem have fixed the issue by having both fuel pumps replaced which is very expensive and in my opinion highly unreasonable being it is a very common issue for Jeep. Upon further research it would seem Jeep Grand Cherokees and Dodge Durangos which share the mechanical characteristics have been having this exact issue for at least 10 years now. I feel it is more than fair that the manufacturer should issue a recall and fix the defect they have obviously known about for quite some time now.
