My 2016 Jeep Wrangler will buck and jerk when on the highway. I’ll be going a steady speed, not changing speed. I feel the car slow down and stomp on the gas but it goes all the way to the floor and nothing happens. When I try to go into the break down lane, the steering wheel locks up and won’t turn. Usually I take the key out then put it back in the ignition and it starts no problem. Recently, the engine has been stalling when I put the key back in the ignition. I usually have to take the key out and sit on the side of the highway for 5 minutes before starting it up with no problem. This has happened too many times than I’d like to admit. Take it to the shop, no codes come up. Sometimes the engine light will turn on when this happens, other times it doesn’t.

After I made a left turn onto a four-lane highway, the transmission stuck in first gear and I wasn't able to get over to the shoulder because of traffic passing on the right side. I was nearly rear-ended twice before finally being able to exit with a left turn. The engine light came on soon after this happened.

For the last 1.5 years the ABS control module light, check engine light, and the traction control light is on. I have taken my jeep to multiple dealers and mechanic shops for this issue and I am repeatedly informed the ABS control module is not in production. It is the only vehicle I own and I fear for my safety. I need to replace this part but the manufacturer is not selling to the dealer or mechanic shops. Can you help me find this part?

Vehicle cel for misfire. Replace plugs and coils. Still happens. Dealership says it needs a new engine? My research shows that this is an extremely common problem with Jeep engines. I am aware of a class action suit regarding this issue. I’m not sure of the status. Vehicle has just under 129k miles and is therefore out of warranty. Jeep/FCA knew these engines had problems and continued to sell them without disclosing the highly likely problems ownere would encounter.

While driving on the highway going approximately 60 miles per hour, I felt something in the engine go quiet and I instantly had no gas pedal power. My foot was pressing on the gas pedal all the way to the floor board and the jeep would not speed up. I instantly put on my hazard lights. The jeep was still running but had no fuel power. I was unable to move over to the right lane of the highway because the Jeep was crawling to a stop and cars were flying past me in the right lane. No warning lights or check engine lights ever came on. My daughter was in the Jeep with me. She called 911. The Jeep came to a complete stop and died. We were stuck in the vehicle and could not exit because cars were speeding past us on both sides of the vehicle. We were almost hit from behind by a semi trailer. It swerved to the right lane at the last moment. We called 911 again and they said police were on the way. A vehicle stopped in the right lane and let my daughter and I exit the Jeep on the passenger side. My daughter was crying hysterically because she was so shook up from almost being hit by the semi trailer. Police finally arrived and called a tow truck. The Jeep was towed to the dealer where it was purchased. The service department inspected the Jeep. Said the Jeep did not register any codes. It started and was driving normal. They say it could be the fuel pump. I’ve ordered a fuel pump but it is unavailable at this time. Not sure when it will come into the dealer. In the meanwhile, I’m terrified that this will happen again. I will not be driving it on the highway at all and will only drive it when necessary to run errands. The vehicle has not been inspected by anyone other than the service department at the dealer where the Jeep was purchased.

By way of introduction, I am a seventy-five year old retired Arizona Highway Patrol officer, having left that service in 1992. In October 2016, I purchased new, a Jeep Wrangler Unlimited Rubicon from York Chrysler in Prescott, Arizona, VIN: [XXX]. Sometime after the purchase, the vehicle began to have a disturbing, recurring problem. While in normal operation, the engine will stop. It is as if the ignition has been turned off. The drill I have developed is, while the Jeep is coasting, to shift to Neutral, re-start the engine, shift to Drive, and proceed. Sometimes, the Check Engine Light activates, and sometimes, although less frequently, this is accompanied with the Electrical Stability Control (ESC) Off indicator light. The first time I documented the phenomenon with a visit to the dealership was 17 May 2023. However, I believe that the problem had happened several times prior to that date. Since then, the vehicle has exhibited this problem numerous times; sometimes at a stop, more often while proceeding in normal operation. The engine has stalled several times on the Phoenix, Arizona, freeway system during heavy traffic. Today, the engine stalled again, but would NOT re-start while coasting. I was forced to come to a complete stop, shift to Park, re-start, shift to Drive, and proceed. Often after a re-start, the transmission has difficulty in going into gear, even while in Drive. I have been advised at the dealership that the problem has occurred many times, to many drivers, but that Chrysler cannot diagnose the problem, and thus can’t fix it. Logic suggests that if a collision has not yet been precipitated by this condition, it surely will be… I have discovered that a class-action suite is being considered. Chrysler must be very aware of the problem, yet is effectively forcing owners of the affected vehicles to operate unsafe Jeeps on the public streets. In my opinion, the Federal Government needs to intervene with a mandatory recall. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (
