We have been without service of the Grand Cherokee L vehicle for nearly 6 of the 11 weeks since we leased the vehicle. The four (4) incidents and ‘repair attempts’ to ‘fix’ the randomly/sudden occurring mechanical and electrical problems were inter-related and causal to the mechanical and electrical blackout troubles. 1.02/27/23 Purchase 2.03/20/23 631 total miles traveled. Dash board blackout. a.Service Dept “reset software”. 3.03/31/23 912 total miles traveled. Complete dashboard, radio and navigation blackout a.Service Dept did not experience random failures, “therefore no repair action was warranted”. 4.04/01/23 930 total miles traveled. While traveling at approximately 45 mph vehicle suddenly seemed to drop gears - the rpm went from 2k up to 6k, the suddenness of the drop of gears had our seat belts tightening. pulled the car to the side of the round and car remained at 6k rpm. I turned the car off, waited a few seconds then restarted the vehicle and proceed home. 5.04/02/23 after starting the car remotely car literally would not get out of automated start mode. I had to turn the vehicle off, wait a couple of minutes before it would start again. In driving the vehicle to the repair shop the power went out of the radio/gps/etc system again. a.Service Dept found RADIO with internal failure. Ordered replacement radio.” b.On inquiry, Service stated the CAM bus (software version ‘AG’ was replaced with updated ‘AI’ version.) 6.04/26/23 1,051 total miles traveled. On exiting a parking lot, I tried to accelerate into traffic, the RPM increased but with zero forward motion. I pressed the accelerator to the floor, the RPM increased but zero forward motion. I then released the accelerator, the RPM correspondingly decreased - still no forward motion. Then reapplying pressure - slowly to the accelerator - the vehicle began to roll forward but at an EXAGGERATED slow pace. I slowly rolled across the traffic lane and forward "running rough".

While stopped at the light with your foot on the brake, the vehicle will accidentally accelerate and almost hit the car in front of you. I looked (my foot was still on the brake). Then, when I try to accelerate, this vehicle fails to get up and go... it's like it's stuck in first or second gear... I avoid the freeway because I'm afraid someone will hit me in the rear end! very dangerous.

I took delivery of the vehicle on February 15, 2023. On May 23, 2023 I was driving 35 MPH and without warning, I lost power steering and the brakes (felt like bricks when I tried to stop the vehicle). The vehicle never slowed and continued at 35 MPH. I had to swerve to not hit other vehicles as I was going through stop lights. I put the car in neutral and it slowed down and then put in park.after about 3-4 attempts of turning off/on, the steering started to work as did the brakes. I drove the .5 mi down the street with my hazard lights on back to my house. At that point the engine light remained on. The dashboard lit up with numerous alerts (I made sure to take pictures of everything). I called a tow truck and sent pictures to the dealership. They had the car for 2 days, called and said that they cannot duplicate the issue, despite receiving and reviewing the pictures I sent. They said no other option but to pick up the vehicle or let the service tech drive the vehicle overnight to see if the issue could be duplicated.
