We own a 2015 Jeep Cherokee 2.4 L FWD vehicle. In the last 3 months, we have encountered ignition issues. We had several misfires when attempting to start the engine. We brought this to the attention of our local auto mechanic, and they were unsure of the cause. We spent over $1500 on inspections and repairs which included spark plug replacement, throttle body replacement, knock sensor replacement, ignition coils replacement and putting in a new battery. We have been to the auto shop several times because the check engine lights keeps coming on and the bills keep adding up. We now received a letter regarding the fact that our vehicle has a recall for catalyst efficiency. According to the notice there may be a loss of catalyst CO/NOx conversion efficiency resulting from the catalyst operating at high temperatures. When the catalyst temperature is elevated, there is a higher rate of misfire, and the misfire can cause immediate damage to the catalyst since it brings unburned fuel and oxygen into the catalyst. I am confident that this loss in conversion efficiency is the reason the ignition misfires in my Jeep. I have receipts and bills to prove that I have spent over $1500 in the last month on engine repairs that still haven't solved the problem. I have contacted a local JEEP service shop who has ordered the part needed for this recall. How do I receive compensation for the money I have already paid for the repairs related to this recall?

At low speeds, typically taking off from a red light, the transmission wobbles (seemingly in second or third gear.) the transmission lags horribly, sometimes causing unsafe situations where acceleration is a necessity. You can't predict the acceleration in this veichle. There is an RPM spike when downshifting causing the car to accelerate up to 15 kmh (even on cruise control) the transmission "clunked" as it was downshifting going uphill accelerating. Experiencing rough idle upon 1st start, and if in drive or reverse, if your foot is not firmly planted on the brake, the car will lunge forward (or backward depending on if in d or r.) respectively with the RPM. With this many complaints, you can't ignore this is an issue which needs to be dealt with.

I purchased my 2015 cherokee 10 months ago and only has 7700 miles but as time has passed the shifting of gears is getting worse. If you let of the gas at 30mph when the car gets to 27mph it accelerates and you can see the RPM increase. When you brake and get to around 20mph the car does the same thing. I have had numerous occassions of almost getting an accident because of this when braking. Its also very dangerous to be going into a turn and the car start to go faster and I don't feel like I have control over the vehicle. During the first oil change I was advised the dealership of the concern and they said you just have to get used to driving a jeep as they run rough compared to cars. I took my jeep to the dealership 11/5/2015 since I complained again and now they do agree "something" is wrong with it but they don't know what due to its not giving them a code. I was given a rental car on 11/6/2015. On 11/10/2015 I was advised I needed a new transmission, the part was being ordered and should be ready in a few days. On 11/13/2015 I called to be advised a part was missing and it would not be ready until 11/16/2015. I called 11/16/2015 to see if it would be ready for me to pick up by 3pm and was told it would not be ready until 5pm, I told them I would pick up the jeep the next day. Today 11/17/2015 my husband went to drop of the rental to pick up our jeep and now it will not start, my husband was told they have no idea what is wrong but they will call later. At this point I do not feel safe having this vehicle and feel chrysler should buy it back as now my resale value will decrease since it will show a transmission replacement at less than 8000 miles.

We were driving cross-country, far from home when the service light came on at 5,645 miles. Fortunately, we broke down in a city with a jeep dealer nearby that could scan the codes. We learned that the transmission control module indicated a problem with the transmission. The dealer recommended replacing the transmission. After 5 days, we picked up our car. We have noticed rough shifting on both the old transmission and the new transmission. We have since learned that the transmission in this make/model vehicle is new and not production ready. Many customers are complaining about the same problems and experiencing close calls with vehicles hitting their stalled car on freeways and busy streets. We are very worried about our safety as the transmission continues to run rough like before. Please investigate.
