2021 Jeep Cherokee Engine Problems

Your 2021 Jeep Cherokee experienced an engine fire while driving on the interstate. You may have noticed a sweet or alcohol smell before the problem occurred, followed by a popping sound from the ignition area and the engine stalling. When you opened the hood, you saw smoke and flames; the vehicle became fully engulfed and was a total loss. The fire department determined the cause was a cable or hose installation failure that created an electrical fire. The fix would require a complete engine bay inspection, replacement of damaged cables and hoses, and electrical system repair or replacement.

Jeep stuttered and jerked on the freeway and then dropped out of gear. I managed to get to the shoulder but the engine would just rev and not go fwd while in drive or manual mode. I could not engage the parking break and when in park, the jeep would still roll forward. I turned the jeep off and on several times but it would not engage in forward gear, but the rpms would go up. I could put the jeep in reverse but no forward gear would engage

automatic stop start that activates when you are at a stop light either gives you and error that it won't work about 1/3 of my driving trips. on 2 occasions it has totally shut off the vehicle leading to all sorts of dash error lights coming on, and requiring the vehicle to be put in park to restart the engine. dealer service says faulty hood open sensor.

The first time it happened was 9/23/2022. I was accelerating away from a traffic light, going to make a left turn, and warning lights came on and the car didn't want to go. The orange check engine light was on, there was a red symbol of a throttle venture and several other orange lights and the car was in limp mode. I restarted the car and the red venture light was out and only the check engine light was on and the car was out of limp mode. A week later 9/30/2022, the same thing happened. I was making a left turn at a light and the lights came on and it went into limp mode. I restarted the car and it was out of limp mode. Just up the street I was making a left turn across traffic and as I went the car again went into limp mode with the red and orange lights on. This time it left me in the middle of a 3 lane road trying to get across. I was almost T-Boned. I took the car to the dealer and they were unable to duplicate the problem. They had the car for a week., 20/5 - 10/12/2022. Then today, 10/18/2022, the same thing happened. The red venture light came on, the orange check engine light came on and some other warning lights came on. One was the traction control light in orange. I was making a left turn out of a shopping center at a light and as I started to go I almost stopped when the car went into limp mode. I tried restarting 3 times and the lights stayed on. I drove it to the Jeep dealer and had them read codes before it was shut off. This could be very dangerous if it happens as someone is trying to cross traffic or on the highway.
