2017 Jeep Grand Cherokee: multiple warning lights

Filed Aug 19, 2026 · Engine, Transmission · MA

On November 23, 2025, I was driving approximately 60 mph in the middle lane of I-495 near Exit 62 in Marlborough, Massachusetts, with a passenger in the vehicle. I signaled to change lanes to pass a slower vehicle, selected Sport Mode, and accelerated. The engine RPM increased sharply and, almost immediately, I heard an extremely loud bang from the engine area. Multiple warning lights began flashing on the instrument panel, the vehicle made abnormal noises, and the engine lost power. The loss of propulsion was immediate while I was traveling at highway speed. Because that section of I-495 slopes slightly downhill and I was already close to Exit 62, the vehicle's momentum allowed me to reach the exit and pull onto the shoulder. Had this occurred in heavier traffic or in a location without a safe shoulder or exit nearby, the sudden loss of propulsion could have resulted in a collision. The vehicle became inoperable and required towing. It was later inspected by an authorized Jeep dealership. The dealer documented a hole in the side of the engine with engine fluid leaking out and determined that the engine requires replacement. The vehicle had approximately 94,298 miles at the time of the incident and had been regularly maintained. The same vehicle had previously experienced a significant engine problem in 2023 at approximately 67,987 miles, involving white smoke, a head gasket leak affecting cylinder 5, and replacement of the cylinder head. I am reporting this because the catastrophic engine failure caused a sudden and complete loss of propulsion at highway speed. The vehicle and failed engine remain available for inspection.

1. failure appears to involve the vehicle’s electrical control and communication systems, specifically (BCM), (TIPM), and/or CAN bus network. The malfunction caused multiple vehicle systems to activate or fail simultaneously, including windshield wipers, warning indicators, and the transmission shift interlock. The vehicle has been at a repair facility since the incident and remains available for inspection upon request. Nothing has been removed/discarded w/o documentation. 2. The malfunction created a serious safety risk while the vehicle was in operation. All warning lights illuminated at once, the windshield wipers activated without driver input and would not turn off, and the vehicle experienced difficulty shifting and limited drivability. The unpredictable activation and loss of control over critical systems impaired the driver’s ability to safely operate the vehicle and created a risk of becoming stranded or disabled in traffic, posing a danger to both the driver and other road users. 3. Yes. The vehicle was taken immediately to an independent service center following the incident and has remained there due to the severity of the malfunction. The service center confirmed abnormal electrical behavior and initiated further diagnostic evaluation. 4. The vehicle has been inspected by an independent service center.

The vehicle had a complete shutdown while being driven. While driving on the highway, several dashboard warning lights began to appear. Within seconds afterwards, the headlights went out, along with the dashboard lights and radio. The vehicle became difficult to steer and then the vehicle lost all power, and could not be restarted. The vehicle was picked up from the dealership the day prior to this occurrence, and the PCM had just been replaced. The vehicle had been towed to the dealership just short of two weeks earlier, after it wouldn't start, having replaced the battery, and experiencing the passenger front window to randomly go down. This incident fortunately did not result in any crash or injury, however, it is only a matter of time if it isn't correctly diagnosed and fixed, as this problem results in an extremely hazardous condition.

Midway through a 2.5hr. drive, I approached a stop sign to make a right hand turn. When I came to a stop to check for oncoming traffic, the Jeep completely shut off on me. The cluster panel displayed “Shift to P to start” and the cluster panel was flashing all the warning lights. (vehicle was still in the ON position) I had then shifted the vehicle to Park, shut off the ignition and then restarted the Jeep. A very scary situation to happen during a normal drive. I have done some browsing and see that I’m not the only one who has encountered this problem. Due to the extreme safety issues at hand, I truly believe Chrysler should be investigating this underlying issue. (I’ve read some people have experienced this while driving on the main road with traffic. I’ve also read that one person experienced this and it ended in a vehicle accident.) This is a serious issue.

I was stooped at a red light on a hill when the light turned green all lights in car turned on the brakes went out and the steering wheel locked. I was on a hill and almost crashed into a wall. I had no control over the car. Don't know how this happened. I was able to mange and pull to the side of the curve. I turned the car on and off a few times and the car went back to normal. I was very lucky I didn't crash into the wall or another car. This was at a busy intersection and I could have kiiled myself or and someone else. I have not driven the car since only my husband because im very scared. Today the malfunction light come on and we don't know if this is related. We called chrysler and explained the situation but they can only schedule an appointment to see the car on 5/17/2021 . This is a very serious issue and im surprised they wont see the car right away. And told us to wait another 5 days. I don't trust this car until it gets checked .

Our 2017 grand jeep cherokee did not start this morning. The brake would not soften so we knew there was an issue. When we put our foot on the brake and pressed the start button nothing turned over but all the lights went on. This happened about 6 months ago and jeep replaced the battery. Obviously it is something else. It appears there is a fuel injection recall but no parts are available yet. When is the eta for these parts? We bought two jeeps because we thought they were safe. After four tries, the car started from remote start.
