2026 Jeep Grand Cherokee Complaints

The contact owns a 2026 Jeep Cherokee. The contact stated that while driving and making a right turn, the vehicle hesitated and jerked while depressing the accelerator pedal. Additionally, the contact stated that while attempting to accelerate from a complete stop, the vehicle failed to respond. The vehicle was turned off and restarted and responded as intended upon shifting into drive(D). No warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed with a loss of battery communication with the computer due to a dead battery. The battery was replaced; however, the failure persisted. The contact stated that the vehicle was previously repaired under an unknown recall. The vehicle was taken back to the dealer for a third time, but no further diagnostic information was available. The manufacturer was notified of the failure and advised the contact not to trade the vehicle due to the safety risk. The service manager informed the contact that another repair a...

This is for Jeep's brand new Hurricane 4 engine. The buyer has no option to chose the reliable 3.6L 6 cylinder in the 2026 Summit model. Theis 4 cylinders throttle response lag, from a stop or slow speed, is EXTREMELY dangerous! When trying to move into traffic from a street or driveway the Jeep just rolls slowly as if it was in Neutral; there is no acceleration. I can floor the accelerator pedal & it takes literally a full 2 seconds every time before the engine responds. All the while the traffic you are trying to safely merge into is rapidly approaching. I took my Jeep to the Jeep Service Department & their response was "NO DTCS. COMPARE TO LIKE VEHICLE, AT THIS TIME WORKING TO SPEC . NOTE ENGINE IS TURBO EQUIP AND MAY HAVE A SLIGHT DELAY UNTIL TURBO KICKS IN". No throttle response for 2 seconds does not fall into the category of a "SLIGHT DELAY". When a vehicle is approaching at 45-50+ MPH and you have no throttle response ... it's an accident waiting to happen.

The contact owns a 2026 Jeep Grand Cherokee. The contact stated that the check engine warning light illuminated and started blinking quickly before remaining continuously illuminated. The vehicle was jerking, and while it was in park, it vibrated excessively. The vehicle was taken to the local dealer; however, the cause of the failure could not be determined. STAR engineers later determined that the spark plugs were inoperable. The vehicle was repaired, but the failure recurred shortly afterwards. The vehicle was then towed back to the local dealer, but was not diagnosed or repaired. The contact requested a loaner vehicle, but the request was denied. The manufacturer had not been contacted. The failure mileage was approximately 788.

Vehicle was purchased new from a franchised dealer. Six days after purchase, at approximately 105 miles on the odometer, the vehicle experienced a transmission failure while being driven with my family, including a young child, on board (warning message displayed - Service Transmission, loss of forward motion, harsh shifting, inability to shift gears while driving on the street). The vehicle was taken to the selling dealer, whose service department diagnosed a failure of the transmission valve body. The diagnosis was made and documented by the dealer's service department, and service records exist confirming the failure. The failed component was NOT on the dealer's possession as part of the repair process; availability for inspection is UNKNOWN, as the dealer subsequently replaced the entire vehicle with a new unit rather than returning the original vehicle to me. Prior to the failure, A WARNING MESSAGE stating "Service Transmission" appeared. The manufacturer was notified of the fa...

I bought the vehicle less than 60 days when it had a major engine failure. The spark plug broke off into the engine and bounced around causing a failure. This is a known problem with this vehicle from the factory, from which I was not aware. At first they said they were putting a new engine in and now corporate is trying to get it out the door asap so they cant be forced to buy back the vehicle as a lemon, which I requested through corporate and started an arbitration process per the contract. The vehicle is being serviced at diehl of moon. The service manager there I am dealing with is James. They have had my vehicle since the check engine light came on and was flashing on June 17th.
