Unintended acceleration is frequently described, sometimes leading to crashes, with vehicles accelerating despite braking attempts. These incidents occur at various mileages, from as low as 500 miles to over 64,000 miles. Several complaints involve the cruise control system, where pressing the "+" button causes rapid speed increases, described as functioning differently from previous models. Safety implications are significant, with four reports involving crashes, highlighting potential risks for loss of control.

Owners of the 2020 Jeep Grand Cherokee frequently report issues with the fuel system, particularly involving the fuel pump. Complaints commonly describe the vehicle failing to start on the first attempt, requiring a second try before the engine turns over. Some owners indicate that replacing the fuel pumps resolves this issue, though it is noted to be costly.
