Vehicle was purchased last month. Grand Cherokee L Altitude. Has <1,400 miles. Check engine light came on. Warning for Electronic stabilizer system. Lost acceleration. Vehicle stalled once coming to a stop. And then once I turned it back on and tried to drive, the vehicle would not accelerate over 25mph. Reset then car drove fine. But then incident occurred again. Glitchy software or modules. This should not occur in a BRAND NEW vehicle. Unsafe.

Two separate incidents, my Grand Cherokee L has less than 100 miles on it. I pulled into a drive thru restaurant and the vehicle completely shut off, still in drive mode. Then 5 minutes later I went to pull into a parking spot, I put the vehicle in park, then it shut off again.

On 7/29/2021, approximately 2pm, driving on Front Hall Rd. leading to our home. Reduced speed to between 15/20 MPH in order to slow down and prepare to turn right into our driveway. Suddenly, the engine shutdown. I had no brakes or power steering. The car came to a stop on its own, since nothing was working. A sign on the computer screen can on stating to put the car in park and restart the car. About an hour later I got the car to service department at I-10 Jeep, Ram dodge in Indio CA.. Today I called to get an update on my car. They said, service was calling Chrysler about the problem. They also said, one of their manager was driving a new grand cherokee L mode like mine and he had same problem with the engine shutting down. They did a computer update on his car, but it continued with engine shut down on test driving it. They advised that a factory rep. would be at the dealership on August 2nd or 3rd to review the problem. This is a serious safety concern when the engine shuts down while moving. Luckily, I wasn't traveling at a higher speed in heavy traffic when the engine shut down occurred. My car has below 400 miles. I purchased the car on July 15, 2021.

Driving Jeep and engine stop, only had steering no brakes fortunately our speed was less than 10 miles per hr and we were in a parking lot. There is only about 770 miles on vehicle and we-€™ve owned the Jeep 3 weeks. Our concern is what would of happen if we were in heavy traffic, it was rush hour at the time? The dealer is picking up car tomorrow but that doesn-€™t fix our concerns!
