Hesitates to start

Filed Aug 14, 2024 · Fuel system · TX

I have a 2021 Jeep Grand Cherokee that has 8506 miles on it, I am the original owner. 7 months ago I was in the neighborhood, and it started hesitating, and the engine stopped, no warning lights nothing, after waiting I started it back up and drove home, and it has been fine until last Saturday. Saturday we were at a busy red light in the turn lane, light turned green I turned, car shut off no warning lights nothing. I was stuck in the middle of traffic and could not move the car. The jeep was towed to the shop, premature fuel pump failure. My problem with this is it could have gotten me killed or my children. Two weeks outside the warranty and I am out an extra 2000.00, because unless your car is dead, or it is a recall the jeep dealership always sends the car back saying they can not find anything wrong, extremely dangerous situation to be put in, I am just grateful I was not on the highway when it happened the second time.

Driving down an interstate at 70 mph, suddenly the car hesitated a couple of times and the engine stopped. I coasted to the side of the road. No warning lights. I am now sitting on the side of an interstate with 18 wheelers flying by and I am miles away from a town. Two and a half hours later we were towed to a jeep dealer. They performed a diagnostic with results being failure of fuel pump and wiring (intelligent power ipac). Dealership made repairs. I feel our safety was at risk because there was 1. No warning/ 2. Possibility of being unable to get off the road in this situation/ 3. Sitting on a busy interstate, waiting for help. In checking online I found more people complaining about the same thing happening to them, so I feel this is not an isolated incident.

I was driving approximately 55 MPH on the highway when my vehicle suddenly lost all acceleration. I received an alert on the dash and a chime - the alert stated "Shift to P to Start" - with no other warnings and no CEL or Check Engine light. Pressing the gas, even to the floor, did nothing. I was forced to brake the car to a stop on the shoulder, shut off the engine, and restart the vehicle. Afterwards, I experienced some slight hesitation which resolved, and then was able to drive the rest of the trip without issues. Having the vehicle lose all power on the highway without warning is a serious safety issue.
