Check engine illuminated in mid-2017, but no codes were present and Jeep appeared to run fine. In Sept 2017, while driving on I-75, the Jeep shuddered and the electronic throttle control light came on, along with the anti-lock brake system light. I took it to the Jeep dealership immediately, but they couldn't figure out the problem because the lights had turned off. They ended up swapping out the spark plugs and two ignition coils. The check engine light came back on a few days later. I was able to pull codes for the throttle position system 1 and 2. in Oct 2017, the vehicle jumped/shuddered and stopped running. I had to coast to the shoulder and leave it sit for 10 minutes. I was able to restart the vehicle and drive it a local repair shop where they were unable to pull any codes and based off of my description of the issues, replaced the pedal assembly and cleared the codes. They said if the issue came back to replace the battery. The issue came back within 5 minutes of leaving the automotive garage, so I changed the battery in November. After that, the check engine light when away, but would come back on sporadically. The Jeep was still shuddering/jumping and would then completely stop after the check engine light, the electronic throttle control, and the anti-lock brake system notification, still. I just took it to another garage (aril 2018), since the previous two had no idea what the issue was. At this point I was still pulling throttle position 1 and 2 codes. This garage replaced the entire throttle body and ran a fuel injection service. Within 15 minutes of me driving away from that garage, the check engine light came on, followed by a softer shudder of the vehicle and the electronic throttle control light. I tried to pull codes when I got home, but there were none--but the check engine light and the electronic throttle control light are still on.

Tipm should be recalled. Front wind shield wipers stopped working in a snow storm and now several of the electrical components are acting funny. Could be a serious safety issue - no lights on the dash working. Need to replace the tipm and was told this is very common problem and the part is on back order - total cost $1200 repair

My vehicle started out with intermittently not being able to start/ turn over or receive electronic signals to the total integrated power module. Over time the problem became more prevalent with other issues occurring along with inability to start. These problems included loss of power to the transmission and position sensors, and cabin lights coming on there own while driving. After several trips to the mechanics it was determined that the tipm was the problem, after replacing the module all problems have stopped.

Engine dash lights ABS, traction control and engine light came on then off then back on will in motion. Also while in motion, an RPM surge occurred which almost caused me to rear end the car in front of me. This surge has occurred twice in the last day so have parked the vehicle for fear of having an accident that could result in bodily harm.

Since I have owned the vehicle the windshield wipers will come on every once in a while when I turn on the left blinker. I also have a problem with the tailgait. After about 3 years of ownership of the vehicle the tailgate hinge did not stop the tailgate from opening up a full 180 degrees causing the elbow joint to come completely out and my right tail light to be shattered. I was told by the dealer ship that this was common issue, but they would not return my calls/emails to get it fixed.

Tipm problems over heating. Safety front turn signals changed to fog light not aware until parked in front of a plate glass window and noticed the problem tipm less than 90 days since it was changed. Hearing of airbag failure antilock brake problems etc all related to the tipm should be cause for concern

When driving my Jeep it has shut off on its own. Today I when from drive to reverse and was trying to park on a busy street and the vehicle just shut off on its own. I had to put the vehicle in park turn the key to the off position and then start the vehicle again before I could drive again. This is very dangerous and could possibly kill someone if this happens on the interstate. Ive read many reports on line of people having the same problem.

On 3 occasions my Jeep Wrangler's accelerator pedal has stuck to the floor. Shifting to neutral would not bring the pedal up. Manually pulling the pedal would not make a change. Twice I had to turn off the car in mid traffic. The third time I was able to coast to the side of the road.

Jeep had random "jolt" while driving down the road at speed. Then a really hard jolt in February that stalled the engine while driving down the interstate at 60 mph. Would not start for 10 minutes, then did. I have taken to two different dealers who say that they can't replicate the problem. Not safe and they should have to figure out the problem and fix it.

While stopped exiting a plaza I turned on my turn signal and it didn't turn on at all. It was operational when I pulled into the plaza a short while before. Then when parked the interior lights would also not turn on with the same control stalk. The next day the other control stalk that controls the windshield wipers, horn when pressed from the steering wheel, along with all of the controls on the steering wheel were not working. I was told by a mechanic that it was the clock spring inside the steering wheel. I researched recalls and saw recalls on the clock spring involving the air bag deployment. I then took my Jeep to the dealership where they determined that it was the lin bus failure internal to instrument cluster. Also the lights on the window switches have all slowly stopped working over the course of the year. Along with the cable from the antenna to the radio has broken leaving me with no am/fm radio. My Jeep has never been stuck in the rain with the top off, has suffered no water damage, has been in no accidents, have been driven with care due to the fact I love it and paid a pretty penny for it. I've kept up with oil changes and tire rotation getting a vehicle inspections every 3,000 miles. I have read multiple accounts of the instrument cluster going bad on 2012 Jeep Wrangler. This is issue should be reevaluated by NHTSA and Chrysler. Chrysler please keep in mind that you have loyal Jeep owners who value their Jeep and don't want to drive anything else, but we also deserve a quality product for our money.

This is a known problem and yet still not recalled the tipm just failed in the Jeep (second one in a month) this time it did it while driving. The Jeep went all ape [xxx]. alarms going off, trying to restart, the speedometer wouldn't work. I thought I was going to crash and die. Happened on the highway and continued when I got on to the city streets the dealer mech said it probably went bad again(in less than a month) I see many people with the same issues(other SUVS from same company have recall on the part, just not the Wrangler) information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

The vehicle power abruptly drops while driving losing anywhere from 100 to 500 rpms. If the vehicle is stopped at a signal or traveling at lower speeds the power drop will shut down the vehicle. The problem is random and very unsafe

The manufacturer of my vehicle, fca has issued a number of recalls eg S33 covering jeepwranglers built 2007-2010 and recently S40 covering only right hand drive Jeep built 2022-2016. These recalls are for clock spring failures resulting in compromised airbag circuits which will not deploy. The clock spring fails because dust gets in it. My Jeep is a 2012 Wrangler with about 10,000 miles on it has had this failure. It has been driven extensively without windows in the desert. I have discussed this problem with fca without success. What is my recourse"?"

My vehicle clock spring has gone out. My vehicle has 45000 miles and is a model year 2012. Other years, specifically 2008-2011 have been recalled for the very same thing. Also 2012 RHD models have been recalled for the very thing. My airbag light chimes and is illuminated when driving the vehicle, whenever I turn left, right or stop or accelerate.

While being towed by our rv on a city street, a fire started under the hood of the Jeep. The transfer case was in neutral. The manual transmission was in neutral. The ignition switch was turned 1 notch to accessory to unlock the steering. The fire was extinguished by the fire department. No police report was filed because the fire was not caused by an accident. Because of the severity of the fire damage, no cause of the fire was determined.

July 26, 2016, we took our 2012 Jeep Wrangler to the dealership after the ABS and trac lights came on. The dealership showed a C102A code and a U140B code. They replaced and programmed the left rear wheel speed sensor, feeling that would solve our problem. On August 18, 2016, in stopped traffic, on a major state highway, the car lost power. We were able to restart the vehicle, but by the time we got it to the dealership, no codes were evident. On September 18, 2016. Driving 60 mph, on another state highway, the vehicle lost power. Fortunately it was a Sunday afternoon and traffic was light. We were able to coast to a side road and after about 4 attempts were able to get the vehicle restarted and drove about 2 blocks to a safe place. We had to contact a tow truck to carry the vehicle 10 miles to the dealership. The service technician was unable to get the vehicle to recreate the code, so he took it home for about 3 days, finally having the vehicle lose power and was able to get it coded. The diagnosis was a tipm shorting out. There was also a damaged clockspring. Both parts were replaced. Total of both invoices = $1,752.25.

Windshield wipers stopped working on the highway in the middle of a thunderstorm, creating a hazardous situation. Took the vehicle into the shop, had the fuses checked, wiper motor replaced, windshield wiper switch tested, and nothing fixed the issue. The issue turns out to be a faulty tipm (totally integrated power module), and will cost over 1200 dollars to replace. This appears to be a widespread issue with Chrysler vehicles.
