At 29835 miles, my 2020 Jeep Grand Cherokee suffered a severe transmission slip/harsh jump. I took it to an authorized dealer on May 5,2026. The dealer charged $559, plus misc. charges of $12.00 and54.25 tax. They performed a transmission inspection, a quick learn to reset points, and noted VEH has an adaptive transmission. Vehicle needs to be driven to accommodate drivers pattern. The transmission is still actively slipping creating an extreme safety risk of sudden power loss in traffic and on highway.

all grand cherokees have an issue where you lose all power to your jeep while driving and cant do anything! ON top of all the electrical issues. HUGE safety problem when your driving in traffic and cant control your jeep randomly
This complaint concerns a serious ongoing engine defect in my 2020 Jeep Grand Cherokee Limited with the 3.6L Pentastar engine. The vehicle experiences ongoing misfire, rough idle, loss of smooth engine operation, and valvetrain noise. The Jeep runs very poorly and feels unreliable and unsafe to drive. The problem appears to be consistent with camshaft and rocker wear described in Stellantis Technical Service Bulletin 09-011-25. The vehicle has been repaired three times at: NJV Auto Center Inc. 27 Orange Turnpike Sloatsburg, NY 10974 Despite being $2,500 out of pocket, the issue has NOT been resolved. This appears to be a widespread manufacturer defect affecting Pentastar engines. Loss of proper engine function while driving is a safety concern and creates risk of breakdown or loss of power. I am requesting the federal safety agency investigate.
My vehicle is losing power every randomly literally cutting off and on. Flashing lights won’t start at time , next day drives completely fine. I do not understand
While I was attempting to pass a vehicle on a two-lane highway, my engine started misfiring and I lost engine power and it almost caused a head-on accident. The engine had to be replaced because the camshaft was worn on bank 1 and after doing some research there seems to be a lot of issues with this engine and the rocker arms which wears the camshaft down. There was a lot of metal in my engine which caused them to have to replace it. I researched recalls and there is nothing but after speaking with the dealership they confirmed that there is a known issue with this engine.
My Jeep Cherokee has lost power twice. Once while idling at a red light and once while going 70 MPH on the Interstate. The gas pedal went to the floor without resistance and would not give any fuel to the engine. The lights were still on so I didn't lose power completely, but the engine was not responding. The recent recal 25V011000 sounds like what happened to my car, but the 2020 model is not included in the recall. I have taken it to the dealership, but they could not find anything wrong with it.
The same thing happened on our 2020 jeep grand cherokee as the recall for the other. We were on the highway and the car suddenly would not respond to acceleration. Like it lost power but it didn't it just stopped responding suddenly
While at a complete stop, depressed the accelerator pedal and reached approximately 30 miles per hour. The vehicle engine RPM's rose but the vehicle would not accelerate. Placed the vehicle in park and then began driving, where the vehicle appeared as if nothing occurred. This took place around 5/2023 at approximately 26000 miles. On 7/18/2023, the same incident occurred where the vehicle momentarily lost power again and would not accelerate even when the accelerator was depressed. This occurred at approximately 30450 miles. The vehicle then appeared to have no further issues beyond that.
