2019 Jeep Grand Cherokee acceleration problems

Filed Apr 1, 2026 · Acceleration, Engine · NY

While attempting to park my vehicle, it suddenly accelerated on its own, causing the car to move quickly toward a tree and a nearby building. I immediately attempted to stop the vehicle by pressing the brake pedal, but the car continued to accelerate. The engine was roaring, and I even tried using both feet on the brake pedal in an effort to stop the vehicle, but it did not respond. The only way I was able to stop the vehicle was by turning off the engine. Due to the unexpected acceleration and my concern that it could happen again, the vehicle was not safe to drive. A tow truck was called, and the vehicle was transported to a mechanic for inspection.

The vehicle lost powertrain upon accelaration. Merging onto a freeway and accelerating my vehicle was as if it was in Neutral. Same with starting out at a stop sign, coming to a turn lane and accerlerating to cross traffic, NO POWERTRAIN... just neutral. This issue was also reported by my mechanic when I brought it in as he test drove it. He contacted the local dealership and they inspected as well. Both came to the same conclusion as to what the issue was. The dealership mentioned having repaired over 30 vehicles with the same issue outside of warranty. This issue is very intermittent, which makes it even more dangerous and harder to diagnose until it starts to happen more often as my vehicle put on more miles. No warning lights or messages of failure. I was almost hit broadside at an intersection and nearly rearended on the interstate at 65 mph. My life was seriously in jeopardy as I panic stricken to get power entering the interstate with my vehicle basically in neutral. I had to pull over and shift to park and then to Drive again. According the local dealership and many forums, Jeep is aware of this issue and has had NO RECALL since the majority are out of warranty by the time they are diagnosed. I am beyond frustrated at the sheer danger this has. I am lucky I didn't get hit, someone else may not be. This should have been a recall before the warranty expired. I am now out thousands of dollars on repair and looking for resolution.

Electronic stability control, check engine and ABS lights are all on. This effects not only my ESC- I have gone out of control multiple times in bad weather, but because of this the cruise control and the automatic starter on my vehicle do not work either. I live in northern VT where winters are tough. ESC needs to be working properly to prevent potential for crash. I have come close several times this winter to going out of control. Also very annoying that the convenience items do not work. Lastly- these lights have been showing on the dash since last summer. I wanted to trade the vehicle in about this time and still do for a different vehicle but can not because of the dash being lit up. This is causing significant financial impact on my household as the vehicle is depreciating day by day and I would certainly not get what its worth with a dashboard full of mechanic error lights.

Vehicle shut-off while in route, in traffic, check engine light then came on. The second time this occurred, check engine light came on and immediately vehicle proceeded decelerate from 55 mph to 25 mph while I was on a highway. The vehicle would not shift to a higher gear and remained in the lower gear at 30 mph on a 55 mph highway, causing me to move off to the side , turn off the vehicle and then restart the vehicle. Check engine light not shown, vehicle operated, except shifted hard. On several occasions I have shared with the dealer at service appointments that I experienced transmission sensor issues causing delayed shifting, not able to shift into reverse or drive from park, vehicles stalled, and rough gear changes, unusual noises coming from the transmission. The engine check light would come on, then disappear shortly after, but not always. Service appointments by a Jeep dealership resulted in them updating software, which I shared did nothing to resolve the problem, so I brought the vehicle back and asked they check the transmission fluid level and cleanliness of the fluid, and whatever else needed to be checked. I was told the transmission was completely sealed and it was fine by the dealership. It was not fine, and the vehicle stalled again, and again it while on the freeway, almost getting into and accident, the transmission locked up and would not move past 30 mph. A warning light did not appear. I brought it back to the Jeep dealership for repairs because it is not safe to drive. I am being told that the transmission is defective by the service department. I asked if they drove it and they said yes. This has been a problem I have been trying to get resolved for the last four months of 2024. I do have service records, in my glove box, and a video of the transmission flashing in reverse. Vehicle is at the dealership for assessment and repair.

Cylinder head gasket(s) has a leak. It limited my ability to speed up and keep up with traffic in a timely manner, requiring me to put on hazards forcing others to navigate around me causing a backlog of traffic and other potential hazards. I have had inspected by two different auto repair shops and both came to the same conclusion, they have also told me that they have seen this issue on the same make and model of my car and other surrounding years of the same make and model quite a bit. check engine light came on, and there was a sensor warning on the dash the day of the problem cropping up. Per the repair shops either this issue has been silently present in my car for some time or the leak in it is very aggressive due to the remaining volume of oil in my engine.
