While driving, the vehicle sends a message that the automatic cruise control has shut down, the car starts slowing down and doesn't respond to pressing on the gas. Only recourse is to move off to the side of the road, shut everything down and turn it back on. The batteries show two miles left on the electric system. This is the second occurrence. Both have occurred at highway speed.

Jeep Cares case [XXX] While driving with Lane Keeping Assistance/cruise control enabled, on a dry clear road (XXX) Between Exit [XXX] and Exit [XXX] - both directions. It has happened elsewhere, but these are our major commuting route. The jeep would all the sudden veer to the right or left out of the lane, and we would have to fight the lane tracking to keep it centered in lane. Our Jeep Wrangler has been in the repair shop for at least 4 occurrences of the issue. 1st was initial diagnosis at about 6,000 miles. Was told that the sensors needed realignment and to bring back so they could keep for the day and it was long process. At that appointment we were told that the alignment was out and needed to be adjusted. During the adjustment, a part was damaged and needed to be replaced, the replacement part was damaged requiring a 3rd part. Time in shop was almost 30 days. 2nd attempt was about 24,000 miles. This time the alignment of sensors was performed, but on test drives, it still ended up pulling to the right and repair shop consulted with Jeep engineers about the situation and determined that at least one part needed to be replaced. Time in shop was another 30 days. After this repair, it pulls even harder and requires additional force to maintain center lane, including more occurrences pulling to the left into oncoming traffic. At 35,000 miles, opened case with Jeep Cares as warrantee is due to expire at 36,000 miles. Jeep currently at repair and after multiple test drives... they are not able to find the trouble. This is a safety issue as it unexpectedly pulls the vehicle into oncoming traffic.

The engine would randomly accelerate , rev and make a whining noise, slip into neutral and I would have to pull over and shut it off sometimes in an unsafe area. Occasionally when I would start the engine it would rev as though I had my foot on the gas and I would shut it back off. I was traveling on the highway approximately 70 mph and cancelled the cruise control to go around a curve and pressed on the gas to merge into 70 mph traffic on another highway, and nothing happened. When I got to the end of the ramp the car was going 32 mph with my foot to the floor on the gas panic stricken. Suddenly the gas engaged and I shot into the traffic trying to avoid me. I took the car home, parked it in the garage and called a local dealership for service explaining the problems I was having. I went to resume my trip in a friends car because I was frightened to drive mine. While I was away my partner went to move the car a few feet to get to the trash barrel and when he put it in reverse the car shot 8 feet at high speed out of the garage and hit a tree. He went to the hospital and the car was taken on a flatbed to the dealership where I purchased it. There is considerable damage. The acceleration problem happened at least 15 times and I have several adults that were in the car and witnessed it. Chrysler did the diagnostics and said there is no defect. I would Never attempt to drive the car again and if I traded it in then an unsuspecting person could be hurt or killed in it.

I rented a 2023 Jeep Grand Cherokee at our local airport (Monterey, California) and drove it to Los Angeles and back for a total of about 700 miles over four days. I am an experienced driver and have been working on cars all my adult life. On several occasions, I attempted to the use the cruise control function to set a fixed speed for my journey. In doing so, I would first turn cruise control ON, accelerate to the desired speed, then MOMENTARILY press the SET button, at which point the vehicle would 'remember' my current speed and maintain this speed indefinitely. Nothing unusual about this, and it's how I've used cruise control in multiple cars over the years. Now, as in a lot of cruise control systems, one may use the SET button to cause the vehicle to accelerate, instead of pressing on the gas pedal. This is also a common way of doing things. One holds down the SET button, the vehicle increases speed, and once the vehicle gets to the desired speed, one releases the button and the current speed is maintained. But not in this Jeep Grand Cherokee. Instead, I found that if I pressed and held down the SET button for a few seconds that the vehicle would CONTINUE TO ACCELERATE long after I had released the SET button. For example: Traveling at 75 mph, I held the SET button for two or three seconds and released it. The vehicle began to accelerate at about two seconds, but continued accelerating for a period of twenty seconds, until I finally stepped on the brake, at which time the vehicle had reached 91 mph. In my run to LA and back, I tested the system several times. In the above example, I used my cell phone to make a video recording of the event. I'm glad to share this with the federal safety agency staff. My general belief is that this is not a one-off defect. It is the way the system is designed to behave, and it's unsafe. There are a few comments on the web pertaining to 2021 & 2022 Jeep products that support what I have said here.

We have a recently purchased Jeep L with 5200 miles on it. Never off road, just a family commuter. Today my wife was driving the car for the second time and the power steering went out completely and it was very hard to turn the wheel. A bunch of other likes came on like the adaptive cruise and active lane management and front collision icons. The dash was lit up with warning including a large steering wheel icon in red. We shut the car down and restarted multiple times and the issue was still there. After 15 minutes of being on the phone to get it towed to the dealer, the issue went away on the next start with just a check engine light remaining.

While driving the vehicle on two different occasions. One was out of town and the screens and dash board going black. I tried turning off the vehicle and back on to reset it. It did not work! Then on another occasion the screen went black would not power off. The dash screen read ALM and cruise control unavailable needs service. I drove straight to the dealership and showed them. They scheduled service the next day. Got a call one of the service technicians was aware of the situation and stated Chrysler needed to provide a recall on the 2023 Jeep Grand Cherokee or create an update for the software system. Vehicle is still not fixed. I do not feel safe driving this vehicle.
