Horn, and all controls on my steering wheel went out. Not sure about my airbag. I thought it may be due to airbag recall but when I went to my dealership to have the recall work done, they told me it was the passenger side airbag only but that it could be the clockspring because they have had several Jeep come in for that same issue. I was actually driving, trying to avoid a car coming into my lane when I found out I had no horn! that's how I found out.

While driving the Jeep shuts off. It is hard to steer and happens without warning. This has happened about 10 times in the last month. It does not throw a code so the dealer can not fix it.

On two occasions, when passing another vehicle, the accelerator pedal was depressed fully and did not disengage. The pedal returned to the disengaged position, but the throttle did not. This happened in between shifts of the manual transmission. Tapping on the throttle did not resolve the condition. I had to keep the clutch depressed causing redline rpms. The ignition had to be turned off while driving. When the ignition was turned back on, the throttle returned to normal. This happened while in motion on the highway.

Immediately after completing work from the air bag recall my vehicle began to accelerate on its own. I would hold a steady throttle and it would all of a sudden speed up. It would last for a few to several seconds and slow down to a point less than the steady throttle. When I would use cruise control the vehicle would vary in speed by five to seven miles per hour. This was definitely a change from the way it operated prior to the recall. I used injector cleaner through several tanks, but the problem persisted. The condition was limited to depressing the accelerator, but has worsened to the point of revving the engine with the clutch depressed and no pressure on the accelerator. I had to cut the engine off due to this uncontrollable rev. I contacted the dealership to inquiry of any such issues following the air bag recall, but before I could complete my question, I was told, "no." Maybe, this issue is coincidence, but it is truly a safety concern. I have searched the net for similar incidents, and it does not appear to be very prevalent. The vehicle currently has just over 68K miles, and zero incidents/problems prior to the airbag recall. I believe the steering wheel is removed when the airbag issue is corrected, and for this reason I question if the issues are unintentionally related.

Driving thru intersection at 40 mph.when it shifted it stopped forward motion.the engine continued to run as I stepped in gas, the Jeep would not move.. I was stuck in the passing lane with cars going. 50 mph. Almost rear ended a couple of times even though I had the hazards on. The turned off and the on. It started right up wouldn't move though. Had it towed to the dealer and they checked for codes and it didn't I have any. At this point they don't know.they have had it for three days. They want me to come get it..I am afraid to drive this vehicle. It went from fine to gliding to a stop, it felt like it was in neutral, then fine was running but no motion I have never had it off road. No sand or gravel. If you can help with this mystery or if anyone else has experienced this, I would appreciate your help. I don't want to drive a car that can stop when it shifts

Stopped at stop light. Car stationary. Out of nowhere engine accelerates on it's own and runs into an 18 wheeler truck that is passing through in intersection. I tried to stop forward thrust by putting both feet on brake, taking out of gear which wouldn't budge, then pulling up on hand brake. After hitting back trailer wheel of truck and Jeep raising back end off ground from impact acceleration stopped and engine idled.sudden unintended acceleration. Manufacturer defect. Accident still under investigation by insurance company. Jeep towed to body shop.

While driving down freeway, the cruise control was set to 62. It suddenly accelerated on its own (as though I had slammed on the gas pedal) while being passed by a semi truck and trailer. When I tapped the break, it did not turn off. When I slammed the break down, it did not deactivate. I was forced to throw it in neutral, and veer into the shoulder. While in neutral, the engine was still revving as though the gas was pressed. Once stopped in neutral, I had to turn off the vehicle completely in order to put the vehicle into park. I let it sit for 5 minutes turned off then start the engine again. I nearly ran into the back of an rv, and nearly rear ended by a semi truck during this episode.

Traction control feature just comes on suddenly while driver forward or tuning a corner at random times causing the vehicle to slow down immensely for no reason. May cause an accident if not corrected. This has happened on dry pavement multiple occasions without warning or reason.

I keep getting a stability control light and that causes the ecb light too pop and then I have no steering wheel controls. This all started after I tried to superchip my 2015 Jeep Wrangler. Sense then my Jeep has been in a local shop for about a month and they have had the brain reflashed and have changed gears for the 4inch lift and much much more. I was driving 65mph when the stability control first tries to take control of the vehicle, talk about scary...anyone out there have this or similar issues, please help.

Between the dates of 3/20 and 8/1 my 2015 Jeep Wrangler unlimited (4dr, 4X4) has been experiencing intermittent cel P0340 while pulling a grade. When the cel occur the vehicle loses significant power and is unable to maintain speed. The traction control system lights come on indicating an error. During this time the vehicle will not accelerate to a safe speed and the traction control systems are not functioning. The vehicle will return to normal operation after turning the key to off then back on. If this is done while moving intermittently the car's security system will engage and the vehicle will not start back up. I have had the vehicle for warranty repair 5 times with this issue. Each time the problem is said to be resolved, but occurs almost immediately.

Driving on a four lane highway around 2pm. I had been driving for a solid hour on the same highway when my Jeep suddenly accelerated. The gas pedal proceeded to the floor even while I tapped and pressed pumping my brakes. I recall an initial odd feeling underfoot prior to the climbing acceleration. I felt the pedal pull away directly after I felt a vibration underfoot. I was not using cruise control nor was it engaged. The engine was cycling loudly and the RPM gauge was climbing in the red, I had no car mat in place because I spilled a protein shake a week earlier and it still smelled. I still checked visually to see if something somehow was obstructing the pedal. I had my hands on the top of the wheel per usual comfort spots. I was like, wait...what the hell is happening?? I had to press as hard as I could on the brakes while pulling the emergency brake up slowly to bring the open throttled car to a stop. I noticed just before turning off the car a red lightning bolt appeared on the dashboard. My new car was 4 weeks new to our family. I am an experienced driver who owned Jeep before in 1989. The gas pedal was so tightly pressed into the floor I could not get the tip of my shoe under to pull it up. I was taken for a death ride for 10 minutes. The car smelled like burning motor! if there was traffic this day I cannot think of the repercussions.
