2020 Jeep Cherokee: check engine light

Filed Oct 5, 2026 · Engine, Transmission · GA

Engine light comes on, whenever you attempt to accelerate from a stop (like a traffic light), the vehicle will coast into the intersection, causing a traffic hazard. It has done this multiple times. At 60,300 miles, dealership told me that engine was not covered. I purchased a new engine, which never fixed the problem. 5 different times they reset dash board, but the it cont'd before I can get home. Dealership gaslights with they could not get pr0blem repeated. But as soon as warranty expire(eed), dealership admides car needs 2nd new engine. $9k.

While driving my 2020 Jeep Cherokee Latitude Plus (2.0L turbo engine), the check engine light illuminated and the vehicle began misfiring with a severe loss of power and abnormal engine noise. A compression test confirmed lost compression in one or more cylinders. The dealer inspected the engine and diagnosed internal piston damage, consistent with piston ring land failure. Research shows this is a known failure pattern in 2019-2023 Jeep Cherokee turbo engines, including a pending class action investigation (Sauder Schelkopf) for premature engine failure caused by lost cylinder compression, misfire codes, and dealerships declining coverage. Reports describe melted pistons and collapsed ring lands, often in cylinder #2, possibly related to low-speed pre-ignition or the PCM incorrectly detecting fuel octane and over-advancing ignition timing. The failed engine components are available for inspection upon request. This failure occurred at highway speed with no prior warning beyond the check engine light, creating a safety hazard from sudden power loss. The engine is a 2.0L turbo GME (Hurricane) engine. Please investigate this defect pattern for a potential safety recall.

My PTU failed while driving 70mph on a 4 lane interstate during a heavy rush hour, I'm 7 months pregnant and this was mortifying for me. I lost all power moving forward and could not accelerate. My RPMS would near red-line. When I pulled on to the shoulder, while trying to not get hit or cause an accident from 3 lanes over, I put my car in park and shut it off, it sounded like a dying weedwhacker. It started rolling backwards without me noticing and I almost rolled back into the outside lane. I put on the e-brake, had it towed to Firestone where they said it was likely the PTU that failed as I have every gear, except moving forward. When they had my vehicle on the lift they moved the tires in reverse motion and there was no noise, when they moved the tires in forward motion there was a loud knocking coming out of the PTU and the tires wouldn't budge. If in park on a decline, park works. If in park on an incline or flat, it rolls backwards. It can drive in reverse, but no forward movement at all. I got it towed to another shop where they took out&opened the PTU and checked the gears on the shaft inside, one of the gears was COMPLETELY MISSING. Just completely disintegrated. There was NO warning that anything was failing on my car. No check engine lights, no noises. Just loss of acceleration. PTUs are on back order 3-5 months right now because they're a known issue on the 2017-2019 models of Jeeps. My Jeep is a 2020 Trailhawk with the v6 3.2l.

Engine warning light came on. Bloomington Chrysler Jeep repair shop said the active grill shutter connector wasn't working. This can cause engine overheating and damage and possibly a fire. I did not have this happen, as I caught it early.

My Jeep keeps going into Limp Mode and not will completely shut off while I come to a complete stop at a stop light. And while I’m driving the engine light comes on. I can cycle it through to get the engine light off. Then it runs fine. This has been happening since after I bought it. I’ve taken back to the dealership I got it from and they couldn’t find anything wrong with it, so they took it to a Jeep dealership and got the same answer. Clearly there is something wrong with it. And could cause me to get into an accident. This is my only vehicle for transportation. The code that shows up is P0934

The engine light comes on randomly. And causes the transmission to bog down and unable to accelerate. We have to pull over and shut the vehicle off and cycle it a few times to get the engine light to come off and then it drives fine. Has happened multiple times and has happened on the highway while driving. I’ve also had the vehicle completely shut off while driving. I’ve taken it to 2 dealerships and was told there is nothing wrong with it. I’m afraid it will cause a bad accident and I’m gonna get hurt if this issue isn’t resolved soon. The Dealership I bought it from Tim Witt Chevrolet in Crivitz Wi. And they took it to Riverside Jeep Dealership in Marinette Wi.
