Cruise Control problems of the 2015 Jeep Grand Cherokee

Driving down an open road, suddenly the "brake now" warning starts beeping and brakes are automatically applied. This has happened several times with no vehicles, etc in front of the vehicle. Happened even after the recall was completed on it for the cruise control system.

The incident occurred on or about Thursday, April 10th 2019 at 12:10am. It involves the brakes of the vehicle not being able to stop the vehicle at low speeds. The entire incident was captured on a high-quality front-facing dashboard camera with audio, video, and gps. There were no injuries. Description of the incident is as follows: while I was on the interstate 10 west freeway in redlands, CA, I maneuvered to the most right lane on the highway in preparation to approach an exit less than 1 mile away (university Ave. ) due to lane closures (left lanes) at the time I was on the freeway, traffic was bumper-to-bumper and very low speed. While in the most right lane and still at very low speed, I engaged the adaptive cruise control feature on the vehicle. Within around 5 seconds of engaging the adaptive cruise control, the vehicle slowed down to a stop because of the vehicle in front of mine had stopped. At that point, the cruise control feature self-disengaged as normal. Only a few seconds later, the vehicle possibly abnormally vibrated. As the vehicle continued to creep forward in traffic as normal, I applied the brakes to stop, but the vehicle would not stop or slow down. As I nearly approached colliding with the vehicle ahead of me, I engaged the parking/emergency brake with my foot, and that did not seem to slow or stop the vehicle either. A second attempt to engage the parking brake did nothing as well. Within a few seconds, the car almost slowed to a stop due to rolling friction and a slight uphill grade in that portion of the freeway. I placed the vehicle in park at this time and restarted the car. After restarting, I was able to drive and brake properly the rest of my short journey home. This entire episode is captured on my dashboard camera, and it seems others on the internet have complained about this issue as well.

Driving my Grand Cherokee on I-40 with cruise control set to 75, I entered a construction zone and applied the brakes to slow down. Instead of slowing down, the car accelerated up to about 90 mph. I was speeding in and out of traffic like a mad person and, luckily, I managed to keep my wife and I alive. Then the brakes were on the floor, I could not disconnect the cruise control, could not shift out of gear and could not turn the car off. After a period of time, we began a slight incline and the car slowed. Then I had control for a short time when the power steering went out; it came back on after about a minute. We were towed to the nearest dealer (70 miles) and the car remained there in order for Chrysler to send a team to investigate. After 4 weeks Chrysler informed me that there was no problem. Tell the truth, I competely expected them to not take blame for this. This was the most frightening thing that has ever happened to me - I thought for sure that we would be killed - weaving in and out of diesel trucks and construction zone. I took out barriers and traffic cones in my effort to save us. I had serious concerns about operating this vehicle again but my thought is that Chrysler probably fixed the problem without taking responsibility for it. I did discover that there is something you can do if you are in this predicament and I wish I had known about it before. If you hold in on the start button for a few seconds, the car will turn off. I had held in on the start button but, evidently, not for long enough. I hope that this message can get out to other Jeep owners and that this action could save lives.

Vehicle's forward collision warning (fcw) system activated a brake! alert with no hazard present. Driver information center keeps displaying message indicating acc (active cruise control)/fcw system not available off & on. Vehicle was in motion at the time of the false alert.

I've read about a recall regarding the cruise control but haven't received the notice and my dealer will not take care of the problem without it. I want it fixed so I can use my cruise control.

I own a 2015 Jeep Grand Cherokee laredo limited, purchased from a dealer new. Last week I pulled into my driveway, turned the Jeep off and went to get out and my alarm system went off. Could not turn it off with either fob, I was even able to start it up and drive. Remote start would not work for 3 days. Cruise control just turns off when it wants while driving on interstate over 60 mph. Gps states I'm off route and freezes in the location where it happened on interstate, normal weather(no overcast/fog). Wipers just start working while sitting in the driveway idling, as you're driving. . . No dust, rain, bugs etc. . . Windshield leaks and rain comes in from behind the rearview mirror/sunglass holder when it rains and you have to take a sharp turn(not with normal turns). . . Leaks down on cell phone which sits in little cubby to charge. The vehicle surges when going under 20 mph, usually when you are trying to start from a stop is when it' worse. Under 25k miles and I am afraid as to what might happen next.

Started the vehicle and noticed that parksense and forward collision warning were not working and every few minutes, the instrument panel, would beep and often display an error message. The messages it displayed were, "service shifter" (displayed most often), "park sense off" (it would automatically turn on and off) and "acc/fcw not working service required" (displayed a few times). Also, the screen (instrument panel) would flicker a few times and beep. The forward collision warning sensor did not work, regular cruise control did not work, adaptive cruise control did not work and parking sensors did not work. I brought it to the dealership and it appears that the acc ball (radar/camera/the thing that looks like the eye ball on the front bumper) had corrosion and all wires were shot. They ordered a new piece with harness and will replace it. However, it is my concern that this is a major electrical issue. The water can easily get into the harness (rain/snow/car wash). It should be still under warranty but what is the solution after the warranty is over? it looks like it needs to be replaced every 16,000 miles (approx. ).

I was pulling my travel trailer south on i65 south at 70 mph and just crossed the alabama state line and saw yellow flashing light and a sign to reduce speed to 60 mph. I was in cruise control set at 70 mph. I pressed the minus shift paddle to slow down but it didn't shift down low enough to slow me down. I then pushed the plus shift paddle to put me back into cruise control. The engine then over revved and shut down and I no longer had power to control forward motion. I coasted to the berm while tractor trailers zoomed by me. I had enough momentum to leave the highway ramp 143 and the come to a stop. The engine push start button still indicated run. I made a right turn as the engine was limping along. I then made another right turn on airport road and engine was still limping. Not knowing what to do I limped on to a dirt road until I came to a grain silo with a parking area in which I stopped. I then pushed the start button which was still in run and the button indicated off. I then pushed the start button and the engine started as normal with normal power and I continued back on my trip to mobile alabama without incident. This problem is a potential safety problem and all owners of my model of Jeep should be warned not to use the shift paddles when in cruise control. The owners manual has no warnings. I called the dealer and then Jeep Chrysler customer hotline 1-800-992-1997 and both told me it was caused by "customer error". I think this control system software should lockout the paddle shift capability when in cruise control or if the speed of vehicle could cause over revving of the engine by down shifting. Maybe a mechanical max rpm switch on the engine would be better than computer software to limit engine revs. This perhaps would eliminate the potential for danger when the vehicle goes into limp mode as it did for me.
