2022 Jeep Grand Cherokee

Last week I was driving 70MPH on the highway when suddenly I got the red wrench icon with the message "Service Hybrid Electrical System" on the dashboard. After about 7 seconds I then got a "Put foot on brake and press start" message on the screen - while still going 70MPH on the highway. At that point the car died. I had no power - the accelerator pedal did nothing. Luckily, I was able to pull over to the shoulder and stop. Then I did what it said and pressed the brake + start button. The car came back to life, but I didn't have the full hybrid system - I only had gas - the car was not using any electrical power as the battery level remained constant and did not drop as I drove. I continued for another 20 minutes where I stopped for lunch. When I returned to the car it started up normally and continued to run normally after that. This is the 3rd of 4th time the red wrench icon with the Service Hybrid system warning coming up, but on the previous times the message went away after about 5 seconds and the car drove normally. This is the only time that it caused the car to completely die on my while on the highway. Apparently, this has been happening to a *lot* of people after Jeep issued a software update to address the 95b recall last year. Many owners are now afraid to drive their Jeep 4xe for fear of it suddenly dying on the highway at high speeds.

I am filing a complaint regarding repeated and dangerous safety failures with my 2022 Jeep Grand Cherokee Overland 4xe, which I purchased as a brand-new vehicle on February 22, 2025. The most critical issue is that the vehicle has shut off on two separate occasions—once while in motion driving up a hill and once during a suspension height adjustment while stopped. In both cases, the engine powered down unexpectedly, a red wrench and lightning bolt warning appeared, and the vehicle shifted into park on its own. I was unable to restart the vehicle immediately, creating a severe hazard. These shutdowns were preceded or followed by system warnings including “Electric Mode Unavailable – Service Required,” “Active Driving Assist Unavailable,” “Night Vision Unavailable,” “Traffic Sign Assist Unavailable,” and “Tire Pressure Monitoring Unavailable.” These alerts began appearing within weeks of purchase and have persisted intermittently, sometimes alongside performance issues such as sudden jolts at highway speed. The CDJR dealership in Northern California and various manufacturer (Jeep/Stellantis) technical advisors have inspected the vehicle multiple times. A software defect has been identified and confirmed by Jeep, but no fix is available. A Technical Service Bulletin 08-003-25 dated January 8, 2025—before I purchased the vehicle—acknowledges this issue. Despite this, the vehicle was sold to me, and I was sent home with it multiple times even after reporting these failures. The dealership and manufacturer technical advisors now consider the vehicle unsafe to operate and will not return it until a software update is released. The vehicle is currently at the dealership and available for inspection upon request. Supporting documentation including service records, warning light photos, and communications with Jeep Customer Care and the dealership, can be provided. I urge the agency to investigate this matter due to the confirmed safety risk and lack of timely resolution.

What component or system failed or malfunctioned, and is it available for inspection upon request? When driving down a busy road, the car completely stalled with loss of power steering, unable to accelerate or brake, power completely lost in car with all safety lights illuminated on the dashboard. Eventually brakes returned, able to stop car. Unable to restart and loss of power for windows. After several attempts, restarted car with warning lights still present- moved to side of Road. Currently at dealer for inspection- stated that problem was "digital crash input code failure" and that there is not a fix for this at this time. How was your safety or the safety of others put at risk? Car stalled with complete loss of control in the middle of traffic, while accelerating at approximately 15-25 mph. This could have caused an accident, but luckily did not. However, car was stalled in traffic for about 30 mins and unable to move car at all- blocking traffic on busy street. If happened on highway, could have been much worse and also had the potential to cause an accident. Has the problem been reproduced or confirmed by a dealer or independent service center? The problem was confirmed by dealer, and said that there is "no fix". According to them, all recalls have been fixed in this vehicle prior to incident and should have fixed this problem by replacing the battery. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Vehicle has been inspected by both dealership service and Chrysler/ Stellantis engineers. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There was 1 warning light message about "EV system hybrid control" needs service, but disappeared after 30 seconds and this appeared about 1 week prior to incident.

While the vehicle is in operation, and without warning, it loses all motive power and coasts to a stop. A warning message is displayed on dash: “Service Hybrid Electric Vehicle System.” The vehicle must be turned off then back on before motive power is restored. This is an extreme safety issue, if it were to occur at highway speeds amidst traffic, the likelihood of serious accident is high. Jeep dealer service says this is a known issue with many Jeep 4xe vehicles right now and no fix is known. This event has reoccurred more than 4 times. The most recent was 5/9/25.

I've had issues with this jeep grand cherokee 4xe randomly shutting down on the highway at speeds between 65-75 mph. The service engine and transmission lights come on and the vehicle itself dies out and will power on but will not start for about 10-15 minutes afterwards. This is the fourth time I've had the issue and the dealership can not pin point a reason/fix for the car suddenly stopping. This last time the power steering went out as well these issues have almost caused several accidents . The dealership just clears the codes after saying the can not replicate the problems I'm having and gives the car back. I've gotten to the point now after almost being rear ended trying to clear the vehicle that I no longer feel safe driving it not only for myself but the other drivers around me a car with a little over 20,000 miles should not be having these issues consistently.

Vehicle has a knocking noise coming from around the engine. There has been a TSB posted regarding the issue described as, "Customer may describe a low frequency vibration noise heard during engine mount actuation while at idle in gear". This is a frequent issue among dealers around my area that are having to replace vehicles outside of the warrant window. Engine mounts in most vehicles last at least 5-6 years before having to be replaced. This is causing a huge distraction with the noise that is a result.

Engine making thwomping sound on passenger side, only after 30 miles of driving. Must be in gear - D or R. 27k miles Jeep Grand Cherokee L Engine mounts suspected. No inspection yet because it's near impossible to recreate in a 'shop' environment. My dealer requires leaving the car for a week and they drive it for five minutes. That is not enough to get this to happen. We believe it has to do with TSB - 09-015-22 On the Jeep Forums [XXX] ), a LOT of people have this same problem.The issue is, you have to drive the vehicle about 30 miles before it appears. This is consistent with all users on the forum as well. Of course this makes it VERY difficult to pin down and near impossible to get a warranty fix since they cannot recreate it. In the TSB it mentions "If the symptom/condition is present and the mounts are not NIK AG or newer, proceed..." This means they know the old mounts are faulty by admission, yet no recall. Clearly everyone is running into this or will. Poor design, should be a recall on these parts - Engine mount.

The brake force will jump suddenly and fall back when the brake pedal is even maintained at a constant level while the vehicle is being braked to a stop or decelerating. This malfunctioning will lead to imprecise control of the distance to the front vehicle. Engine Wobbling when it is fully stopped with "D" gear engaged, especially when the transmission temperature comes up after a few hours of driving. It can be clearly felt that the entire vehicle is bouncing with the engine. Engine misfires when crawling after a cold start. Engine speed will fall suddenly and then back up. The vehicle will shake badly, which can cause improper reaction and improper operation of the vehicle speed. The passenger seat squeezes the center console on the right side and the plastic panel comes off, which exposes a sharp edge to the passenger's lower body. After the dealer's inspection, there is no obvious cause for this defect, passenger and center console are all in their places. The rear quarter window on the passenger side water leak. Metal rattling noise from the left front side (driver side) of the cabin when the vehicle is running on a bumpy road, especially in hot weather. Noise comes from the rear left suspension when the vehicle is decelerating.
