In owners’ own words
Source: NHTSA complaint databaseFiled with NHTSA by the people who own these cars, about the electrical system. Quoted as written, with anything identifying removed; unverified reports — what was said, not a finding that it was true.
My 2018 Jeep Grand Cherokee has been submitted to the dealership for a faulty SOS feature. The SOS does not connect to emergency services and does not shut off. The system stays engaged until a fuse is pulled in the battery compartment under the front passenger seat.
Vehicle exhibited sudden unintended acceleration on two separate occasions, and caused an accident involving property damage. The vehicle, which had been on cruise control, was completely stopped in traffic for 30-45 seconds on I-95 in south carolina.
After turning on the ignition and putting car into reverse the reverse light flashes and car will not go into reverse, same for putting into drive. Engine light stays on. This problem only lasts for a few seconds and then the car can go into reverse.
Electrical system malfunctioned while driving on a city street, dashboard lit up and the vehicle would not switch gears. Wipers started going and message popped up on the screen to not turn the vehicle off because it may not restart. When the vehicle was turned off it would not restart and it was stuck in the run position.
Vehicle is equipped with the 8.4 inch uconnect/nav 4c touch screen. This system/screen controls the radio, climate control, heated/cooled seats, phone, navigation, etc. after driving the vehicle for 20-30 minutes using only the radio, the touch screen becomes hot to the touch.
