I am having difficulties with my brand new purchased Jeep Wrangler and it has been in and out of the dealership since September with no resolution. This Jeep is 19 months old and we bought it brand new from sahara Jeep. Despite the fact that it does run the engine suddenly chooses to lose power while IżM driving and accelerating or decelerating is not an option. Not really safe especially when my daily commute to and from work is over 20 miles one way on highway speeds. The engine has stopped about 6 times and two times of those has been on highway speeds which is not a safe place. I have been lucky that when it happened that I have not been rear ended or even worse have caused any accidents. I have continuously brought the vehicle back to chapman and they are unable to find any issues and then now the vehicle is at sahara and I am getting the same answers. Although error lights have come on and I have given the dealerships those they are still unable to diagnose what is making the vehicle engine suddenly stop.diagnostic testing keeps coming up negative. I was given a flight recorder to attach to my Jeep to help assess the issue. The vehicle died and I was able to successfully run codes through their recorder (supplied by Jeep) and had the vehicle back at the dealership the next day. I was told that their computers were down and unable to read the codes but they did capture something but had forwarded it onto corporate to read. A couple days later with no update I contacted corporate and was told that they were unable to read the codes because their system was also down and I would have to do it all over again.

Oil filter housing. Dealerships are not replacing this faulty housing unless it's made a nationwide recall. This is a problem for quite a few chrylsers - Jeep. Please look into the 2014 & 2015 oil filter housing cracks and dealers will not fix if not under warranty and if they have not changed oil.

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.

Engine light comes on and remains on until dealer resets it. Code indicates that cylinder #6 misfire. Since Jun 20 2015 and up to 4 Jan 2016 the vehicle has been in the shop 7 times. Town time has already reached 24 days. So far they have replaced the cylinder head, removed the head a second time, updated software, and replaced the cam shafts, plus a number of other things. The star team at Chrysler/jepp has been involved with no success. First time the light came on and remained on was 18 May 15.

Engine problems: Starting summer 2015 engine shuts off while driving, accelerating, slowing down, stopped engine will not go back into gear engine loses power when accelerating or cruising brought into dealership (purchase location) approximately August 19th 2015 released September 2nd 2015 problems persisted brought into different dealership approximately September 14th 2015 released approximately September 26th problems persisted brought into dealership September 30th 2015 still in custody as of October 8th on September 29th, I was taking an on ramp for an interstate. The ramp is an uphill, hair pin turn that then turns into an off-ramp for oncoming traffic. I have never experienced an issue accelerating and merging into the interstate traffic here. However, this afternoon I was not able to get the acceleration that I expected. When I ran out of ramp room, I would have needed to slow down significantly in order to allow the side by side tractor trailers to go by. However, because of other cars that were behind me on the on-ramp, that was not an option without possibly causing an accident. So I merged with as much power as I could get, which was not enough. The closest tractor trailing came barreling down upon me quickly with horn blaring. On September 30th, just a couple miles away from the dealership, I was the first in line at a red light. The Jeep shut off. I could not get it back into gear. It just remained in neutral no matter which gear I tried to put it in. I shifted in and out of park and other gears turned the vehicle off and back on many times. A few times drive would engage but then the engine would shut off again after a few feet. I finally got it into gear and accelerated quickly hoping to cover a greater distance and it worked. I was able to finish my trip to the dealership.

I was driving at highway speed when the check engine light was activated. The automatic transmission was not shifting properly, and did not seem to downshift after slowing down to proceed through toll booth. When I attempted to accelerate after paying the toll, the engine began to slowly accelerate as if it was in fourth or fifth gear. Shortly thereafter, the oil light began to turn on and off intermittently. I made it to a Chrysler/Jeep dealer and found a puddle of oil under my car and there was no oil registering on the dipstick. After the Jeep service department eventually looked at my car, I found out there was a cracked oil filter adapter that had to be replaced. After doing some research, I learned that this was not an uncommon problem in Jeep. I imagine that I was fortunate that the engine did not seize or catch fire, which obviously has the potential to cause serious harm.

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.

6-speed manual: While stopped at lights, crossing intersections, and normal driving on roads, day/night and warm/cold, engine stops for 2-10 seconds. It has stopped when passing other vehicles requiring full break application to avoid oncoming traffic. In intersections and when the clutch was pushed in to help coast through intersection, there was no power steering to help turn the wheels! the dealerships insist that there is no problem and engine could not cut out while driving? this engine problem has occurred at least 30-40 times.

Wrangler 4WD 6-cyl

Check engine light flashes when going uphill. Dealer claims to be unable to read the code if engine light does not stay on. Has been in for service 4 times for same issue. Once, dealer replaced a single engine coil after reading a P300 misfire code. Engine loses power and freeway speed becomes impossible to maintain for several minutes even after cresting hill and driving on level surface.
