Cruise Control problems of the 2016 Jeep Cherokee

The contact owns a 2016 Jeep Cherokee. The contact stated while driving 55 mph with the cruise control activated, the cruise control system failed to maintain the set speed. The contact stated that the speed fluctuated up and down erratically. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 40,500.

I was driving on the freeway with a friend, had my cruise control set and the car started speeding up, I pressed the brake pedal to disengage and it didnt so I pressed cancel on the steering wheel it just keep going, I keep tapping the break pedal, finally it just went off,I asked my girlfriend if she felt that, she said yes I thought you were doing it, I wondered what you were doing. . I had a recall on my car eariler for the cruise control and took it in but if this is the same issue it wasnt fixed properly. I called Jeep and they said since there are no recalls on my vehicle id have to pay for the repair. . I believe this is the same issue. . There are only 21683 miles on my car. .

I was driving down the highway with my daughter and my dog with me and had the cruise control set to 75 mph. There is a part of the highway where the speed limit drops to 65 mph so I slowed the vehicle down to 64 mph when it suddenly revved up to 5000 rpms and hit 75 mph again. The car has been surging lately but I thought it was from the weather getting colder. The car accelerating on its own going down the highway, especially to 5000 rpms, I know is not just the weather. There is something wrong and I have only made 1 payment on it about to pay my 2nd one. I just bought this car August 21, 2019 so this should not be happening already. Also there is a rattling in the engine.

When driving in the mountains of west virginian having the cruise control set to 70 everything works fine until you come to a steep down hill grade. Suddenly I would look down and I would be doing 90 miles a hour and the engine rpm is over 5000. This happened 4 times. 3 times I would just touch the brake and the engine rpm would immediately go down to around 2000 rpm. One time I hade to stand on the brakes for several seconds until the rpm would go down. I almost lost control of the car one time. My son drove through the mountains on our way to the east coast and I drove through them on the way home. He told me the same thing happened to him several times. I have had the car for just over 2 years and the cruise control works fine. The only time I have problems is in the mountains on a down hill road.

As of lately, the speedometer toogles up & down through a set of numbers even after attempts are made to reduce speed especially when on cruise control. During cruise control vehicle accelerates beyond set limit & requires extreme force to decelerate. It happens randomly as does many dangerous issues mainly after a software update takes place with the vehicle. If the updates don't cause acceleration concerns it causes vehicle to shut off in traffic & over the last several months a few high risks for major traffic accidents were only avoided by the swift maneuvering of other vehicles or myself when possible to avoid collision. Never before experienced so many malfunctions of mechanical/technological problems from a vehicle. As for if the vehicle was stationary, in motion, on a city street or a highway, turning, braking etc when these issues occured the answer would be my Jeep has stalled, loss speed, shut off and/or speed up under all these conditions. Dealership has me bring it in and they flash the system to "correct" the problem. That is until the next update or some software malfunction causes unexpected scary incident to arise like now with the cruise control that needs addressing.

My Jeep has been having a disturbing problem with the cruise control for months. Periodically, cruise control accelerates on its own way above what it's set at (e. G. It's set at 75 mph on the highway and suddenly it accelerates to 95 mph). I have to slam the brakes until it decelerates and reset the cruise control. When I was setting up my routine oil change appointment on the lithia app, I noticed a recall that was exactly for the problem I was having. But my Jeep was not included on the recall. I called 1-800-853-1403 on 7/24/18 and was told my Jeep was not on the recall list but to ask for diagnostics test for u63. At my appointment, 8/10/18, at lithia santa fe, the diagnostics didn't show anything. I had to pay $157 for the test! I called the 800 number again and told them I want to go on record that I reported the problem and tried to have it addressed in case I have an accident related to it. The technician told me they �cleared the module� and that might take care of it. I don't think I should have had to pay for the diagnostics and I think this should be remedied under the recall.

My vehicle was on cruise control at 55 mph and during a downhill slope, the vehicle accelerated and rpms jumped to 6-8,000. I could not get the cruise control to shutoff and stop acceleration. I almost hit the car in front of me. Has happened twice now. I have also had it lurch forward at stop signs when taking off.

While using cruise control, traveling down a moderately steep hill, the speed would not remain constant and the engine would actually engage to accelerate the vehicle rather than govern the speed at the mph setpoint, without having my foot on the throttle. The tachometer would show the engine rev increase and you could hear the engine as well when this happened. Obviously a very dangerous situation. Took the vehicle to the dealer and was told the car and cruise control were operating as designed!.

1) car stalls at random without warning and no apparent cause. I've had the car stall at low speeds after turning (able to restart) but most significantly an incident occurring 7/9/2017 when I lost all acceleration on the interstate at 65mph while towing a 3500lb trailer. The tachometer and speedodometer dropped immediately to zero. Total shutdown. Concurrently all the electronics shutdown, including power brakes. Thankfully I was on a flat stretch of road and was able to drift into the breakdown lane. The car would not restart; no electrical components with the exception of the hazard lights and emergency brake were functioning. Car had to be towed. 3) cruise control fails to maintain car speed on moderate downgrades. . . Rpm's will shoot to 5000, then car will "take off" increasing speed by as much as 15 mph more than control is set for. My complaints have been verified/replicated by a Jeep Chrysler service center but they have stated they can't fix the car because they do not know what is causing the issue.

While in cruise control and going downhill, vehicle will often downshift and quickly accelerate about 10 mph. Cruise control will regain conrol and slow to set speed after a few seconds. Thus far I have observed this behavior at set speeds of 45 mph and at 68 mph. I have not driven the vehicle enough to know how consistent the behavior is or if the behavior is only at specific mphs.

Does not hold the selected speed when going down hill with cruise control set. Transmission shifts down but does not stay in one gear, shifts up and down.

While using cruise control, traveling up and down hills, the speed would not remain constant. The variation of the speed would be between negative 5 mph to 16 plus mph, without my foot being on the throttle. At times while traveling down hills, the engine would actually engage to accelerate the vehicle. The tachometer would show the engine rev increase and you could hear the engine as well when this happened. I have an incident of this on video in which I had the cruise set to 45 mph and while traveling down hill, the vehicle accelerated to 58 mph, without my foot on the throttle. I wanted to use the cruise control to get better gas mileage on the highway, but would often have to hit my breaks to avoid the vehicle in front of me due to rapid acceleration. After discovering this issue, I refused to use it as a result. This is not my vehicle, but a rental vehicle. This issue happened the entire time period I had the rental I have video to prove this but am unsure how to upload it as according to your website it is not a supported file format. I will provide upon request. My husband, who is an faa a&p licensed mechanic, filmed the video while I was driving, and suggested I report this issue. He also did some research on the internet to determine if this is a known issue with the Jeep, and found that it appears to be, as many are reporting similar issues.

While driving 45 mph on straight highway going downhill under engine power with cruise control on and set at 45 mph transmission downshifts and upshifts abruptly and rpm increases and speed surges increases to 63 mph. Going down same hill ar 45 mph without cruise control on next trip car coasts only to 50 mph.
