Service 4X4 light had come on, intermittently for over a month and is now staying on. I have not used the 4X4 system in over 6 months. No reason for it to need serviced if it hasn't been used.

My transmission has me feeling so unsafe. After putting my vehicle in D, when I attempt to accelerate, the car makes no attempt at moving and then suddenly jerks forward. This happens when leaving my driveway, moving past a stop sign and in traffic. Obviously the latter are especially frightening. Jeep dealership said it could be software, but after an update, the problem continued to worsen, rather than improve. It is now to the point I feel completely unsafe in my vehicle. It has not been recalled, but I'm shocked; especially after seeing how many of the same complaints are out there. I desperately want my transmission replaced (not "fixed") before my warranty is up. Either that, or a new vehicle!

The contact owns a 2015 Jeep Renegade. After the gear shift was switched into the drive position, the vehicle reversed without warning. As a result, the contact's vehicle crashed into another vehicle. The contact discovered that the gear shift failed to go into drive. The air bags did not deploy. A police report was not filed and no injuries were sustained. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 13,000.

The contact owns a 2015 Jeep Renegade. The contact stated that the vehicle experienced a loss of power and lack of acceleration. The failure occurred only when the vehicle was cold. The vehicle was taken to the dealer where it was diagnosed that the transmission was defective and needed to be replaced. The vehicle was repaired, but the failure recurred. The manufacturer was notified of the failure. The failure mileage was approximately 29,936.

At 1040 miles while going up a 7% grade in 100+ degree temperatures. The transmission down shifted and immediately lost power then began 'lunging'. display showed "place vehicle in park prior to selecting a gear". after waiting several minutes restarted vehicle but as soon as it needed to shift it would do the same stall out. This exact behavior also occurred on the same section (within 2 mi) of highway at the following odometer readings: 4811, 5202, 28928, 29580 and 29623. Common RPM's are around 3500 but varies somewhat each time and usually between 50-65 mph. The car is being driven in full automatic mode and is unresponsive if attempting to switch to manual mode once it starts. Cruise control was only used the first time. I quit using it after that in case there was any relation to the shift selections. The gap in the mileages indicate the almost almost 3 months that the dealership had the vehicle and the time that I did not experience the problem- cold months only. Many of the occurrences are with days of each other and or after picking up the vehicle. The vehicle also experiences extremely hard low speed shifts (from a light or stop sign). The stretch of highway I drive daily is very busy and a main corridor from the neighboring city to my rural town. It is dangerous to suddenly drop "back" on speed so dramatically.

2015 Jeep Renegade: Vehicle shifts hard; like a canon. Took vehicle in to dealer and they said it just needed an update. Problem still not fixed. Vehicle makes a ringing sound like a phone when at highway speeds of 65 miles per hour. Vehicle rattles a lot especially in the speaker areas and also the driver side seatbelt area. When I took it in to the dealer to have them figure out the rattles they said that they could not find it. The seats do not heat up well. When it is turned on high, it feels like it is on the low setting still. When the steering when is being turned at any speed it makes a creaking sound.

Car has previously stalled when accelerating and had continuous hard shifting causing increased panic attacks and anxiety two military vets. Also car has difficulty braking and has stored "failure to brake" code. Car has now been seen 3 times for transmissions issues and twice for braking issue. Current stored codes: C1431 U1001 U010 C2208 C2209 C221B U2003 U2004 U1700 dealerships states, "could not duplicate concern"

When using "autostick" to downshift the 9-speed automatic transmission the computer "unloads" the drivetrain and at times it feels like the car is being shot out of a canon. This is worst at higher speeds, when towing, and on downgrades. It happens when shifting from 8 to 7 and 5 to 4. the dealership told me that the car is operating "as designed" so they can't do anything. The other fix is a software update but I've gotten all available and the problem persists. Jeep has the same attitude. When using autostick to downshift from 5 to 4 on a 9% downgrade the car speeds up from 45mph to 50 mph during the 2 second shift. Then, because of overly conservative downshift protocols (the engine has a max RPM of 6500 but during downshifting the computer never lets it exceed 3000 RPM), the computer won't let me downshift the transmission at all, there is no engine braking and the car keeps gaining speed. As long as the brakes are working there is help but without normal brakes there is no way to slow the car. The computer keeps saying no to a downshift and there is no emergency brake, only a parking brake that is either all off or all on/rear wheels locked. Locking the rear wheels at 70mph, or worse turning the wheels to make a turn with locked rear wheels results in a spin and then tragedy. I took delivery of the car new in October of 2015 and it has been doing this the whole time. One of the dealer mechanics told me that the reason this happens is that for those shifts a sleeve on a splined shaft has to slide so all pressure has to be remove from the sleeve. It sounds like a bad design for the sake of fuel mileage without due consideration for safety.

This is an update to an earlier complaint (#10826148) about my 6-speed manual 4X4 2015 Renegade latitude (with ~6490 miles on it) which was revving uncontrollably, popping out of cruise control, difficult to get into and out of gear as well as exhibiting poor fuel economy. At first, the dealership service department said they couldn't replicate any of the problems, but I insisted that they keep the car and drive it further. They did and were able to see that there was a problem. That was nearly one month ago. They kept the car for 3 weeks for what was described as a problem with the clutch, a part for which (the throw-out bearing) was on back order. I picked up the car this past Friday 3/11/16, drove it home and parked it in my garage, happy that it was fixed. Or so I thought. Saturday morning, less than 24 hours since bringing it home, as I was preparing to go out of town, the car would not go into reverse, and there it sits, stuck in my garage, to be towed back to the dealership. Thing is, I had not tried out the reverse on it when I picked it up or got it home. I had a straight run out of the garage when I picked it up, drove around the building and then straight to my home. I'm wondering if they had not done so too. Now that it is nearly 30 days out of commission, I will probably try to get the car declared a lemon and ask the dealership to buy it back. I don't want to do that but I do not feel safe in it, even if they were to fix the clutch again. NHTSA, please look into our cars-I have read the complaints and it seems that something is very wrong with it!

My new Renegade started hesitating when accelerating and was not shifting properly. You could tell it was stuck in gears too long before shifting. Took it to the dealer 3 times. First time they updated the computer even though they said they did not notice any issues during their test drive. Second time the tech said he felt it and fixed the problem with a module update. It did ride great after that-but lasted for only one day. Took the vehicle back for the third time and they did nothing-said they could not replicate the problem. The whole time I am thinking maybe I am imaging the issue, only to speak to another customer in the waiting room about her ongoing issues in her 2012 Cherokee-same transmission as in the Renegade. Now, the interior lights dim and come back on and the front wipers come on when you turn the back wipers on. The vehicle has 2070 miles on it. After reading the other complaints (car stalling while driving at highway speeds) I am concerned about driving it. The service man said I could bring it back-which I am going to tomorrow. But if they insist they don't feel it I am not sure what my recourse is. Do I have to wait till I crash due to a system defect>

On February 15, 2015 with 8260 miles the service transmission light came on and the vehicle would not accelerate. After having the vehicle towed to the nearest dealer I was informed that it was an issue with the computer and it had been reprogrammed. On February 22, 2015 the same error occurred. The vehicle was towed to the nearest dealer. I was informed the next day that the transmission would need to be replaced.

I purchased my 2015 Renegade latitude 6-speed manual transmission vehicle last fall and found that from the beginning at times I had difficulty getting it into gear. I've been driving manual transmission cars (all sedans until this) for nearly 35 + years so I'm familiar with how to shift etc. I knew and expected that there'd be a learning curve as every vehicle is different. But by now it should be resolved. Instead, it has worsened. I have maneuvered around the minor problems -those at lower speeds-having to downshift a few times when I needed to upshift (I rely on sound and the rpms as my guide). The car now has 6200 miles on it (a mix of back road driving with Suburban streets and some highway) and it is now revving uncontrollably at times, throwing me out of cruise control, acting as if on ice when there is none, surging forward when I haven't accelerated. And the advertised 31/27 mpg has not happened. I am now down to 23 mpg. I will be dropping it off tomorrow for an oil change and for them to look at this revving problem and the low mpg. I am afraid to drive this car, which I love very much, aside from the problems btw. I am concerned because I see that there have been complaints listed on sites about just this thing and it is a reminder of the out of control acceleration problems of cars in years past (like with Audi). Please let me know what to do besides taking it into the shop. I see below that you ask when this happened: As I said, from the beginning-I noticed that when I backed out of my driveway and put it into first and then shifted into 2nd, I'd have to go back to first. Then, it would surge ahead as if it were in third or fourth. That has continued.. the scary issue is the revving in traffic last week. I have not driven it since then.

At around 980 miles, the car started loosing power and the transmission was jerking a lot. Then I came to a condition where I cannot control the speed anymore. I had to stop my car in the middle of hwy-15 at night. This happened on 1/16 and same problem recurred after the first fix attempt. This is a critical safety issue. I cannot imagine driving this car again. Just after 2 weeks, after driving about 10 miles, the same problem happened. This issue seems to be prevalent. It needs to be investigate. I am going for a lemon law this time....

The 2015 Jeep Renegade has had about 800 miles when the problem appeared. I was driving on a freeway at 70 mph. All the sudden, the car started jerking and the car would not accelerate even when I push the pedal as I intended. So I got off the freeway and started driving local at lower speed, and the car was acting even more weird. The car was jerking and came to stop. The engine was on but the car would not go. Luckily, it was at night time and in residential area, there were only few cars around so they could drive around. I changed the automatic mode, 'd', to the semi-manual mode. The frequency of the jerking reduced but the car came to a stop again while I was driving about 6 miles to drop the car at a repair shop at a mfg authorized dealership. This could have caused serious property damage and bodily harm. I was lucky that there were many cars around at the time and the car did not stall on the freeway. I am not an expert, but the problem seemed to be related to the power train (and speed control possibly.) I hope I am the only person with the problem. This problem must be assessed and appropriate action needs to be taken. My car is currently at a repair shop and will be assessed, hopefully tomorrow.

I bought my vehicle approx May 2015 drove 7600 with virtually no problems. All of a sudden began having shifting issues with a bad hesitation between gears to the point where I didn't think the vehicle would move then it did. Took to the dealership & they did an update on the transmission software. That made it better for only a short time. My car started doing it again but was a lot worse. Car had 14000 miles on it & it was jerking into gear. Took to dealership & they verified the rough shifting said they were told by Chrysler to do a relearn procedure on transmission & that sometimes will correct the issue. The transmission isn't jerking into gear at the moment but you can still feel it shift into gear. Think this problem really needs to be researched.

Just purchased a new 2015 Jeep Renegade one month ago, and my daughter was driving it to work one morning and the vehicle lost total power in the middle of the road and would not move, had to get it towed to the dealer where it was purchased and they called me and told me the transmission needs replaced. The vehicle has 2000 miles on it. Updated 09/15/15

On 7-23-2014, when attempting to back up, the Jeep would not move and no less than 5 warning lights came on. Multiple messages:service hill start assist, service engine, service electronic parking brake, service transmission. Shifted to park, huge clunk, shifted back to reverse, huge clunk, then was able to back up. Shifted to drive, wouldn't move. Repeated process, clunking transmission, then moved forward. Drove home slowly then had towed to dealer. See online that the 9 speed 948te auto transmission is a problem. Why isn't anyone looking at this?? dealer has Jeep and has done 7 software updates and aren't sure if it will fix the problem. I paid $28,000 and don't know if the &#@% thing is going to do this every time I leave the driveway. Please look into this. I understand the 2013 forward Cherokee has the same problem and no one is helping these owners either.

Hesitation shifting between multiple gears. Lunged forward without warning at a complete stop. Made manufacturer aware of issue.

- Yakima, WA, USA

My 6 week old Jeep Renegade won't start. I inserted my key into the ignition, I turned and briefly the electricity went on but the engine didn't turn. Then I went to try again and everything locked up. The key was stuck, the gear shift was locked and wouldn't move, and the vehicle would not turn on. Finally got the key out but when you put it back in, you cannot turn the key. Nothing works, it is completely shut down. It appears as though the lock cylinder may be broken. Very pissed off.
