Cruise Control problems of the 2014 Jeep Grand Cherokee

In the process of parking at my sister's home, I took my foot off the accelerator and started to brake. The car did not slow down. I continued to brake, but the car kept going forward with increasing speed. I was able to steer and not hit parked cars, but went into the lawn hitting a set of contractor's scaffolding sending them flying into their house and patio. The car finally stopped on top of their well head, destroying the well cover as well as the protective pipe for the well head. Further internal damage was done to their well, as there was no running water in the house. A tow truck had to come to lift the car off the well head to avoid any further damage. I had been using the cruise control earlier in our trip, but it was not active at the time.

Multiple problems with the forward collision warning (fcw) and adaptive cruise control (acc) systems 1) system will issue false brake warnings (and apply brakes if enabled) on clear straight roads with no other cars or obstructions. 2) system will disable itself at random intervals disable itself for a period of time (10-20 minutes). Only notification is brief "fcw/acc system disabled" notification in gauge cluster - no audio warning that important safety system disabled itself. 3) when using acc, when vehicle resumes set speed after autonomous braking, vehicle will accelerate into back of next vehicle ahead - have to manually intervene and apply brakes to prevent collision. Note that this vehicle uses a bosch lrr3 radar sensor system for the fcw and acc features. Vehicle has been into Jeep dealers for service for this issue five times, and even after opening star case with Jeep/Chrysler fca, still no fix for this serious safety issue.

Adaptive cruise control and collision avoidance did not work properly, and resulted in a collision. I was driving on a highway, relying on the adaptive cruise control and the automatic breaking, a feature of collision avoidance. There was a slow down in traffic, and although the system slowed down and applied break, it did so too late to stop car. As I got too close, I applied steady pressure on the break, but I still hit the car in front of me, who then hit the car in front of them. No significant damage to either of the other cars, and mine has minor cosmetic damage, and the adaptive cruise control is now not working properly. Could have been significantly worse. Makes me really question the potential for self-driving cars.

Tl- the contact owns a 2014 Jeep Grand Cherokee. The contact stated that he had experienced several failure on the vehicle. The contact stated that while driving at various rates speed, the contact would hear knocking and banging sounds coming from engine without warning. The warning light eventually illuminated after the issue persisted for some time. The contact drove the vehicle to a dealer(port jervis Chrysler Jeep Dodge parts 131 kingston Ave, port jervis, NY 12771 845-856-6211) where they replaced the transfer case; however the failure continued to occur. The transmission had ultimately been replaced twice by an independent mechanic. The contact also stated that as he was closing his rear hatch, the contact saw smoke coming from both license plate bulbs. The contact immediately shut off the vehicle and removed the bulbs from their sockets. The contact called a dealer(dealer unknown) to have the bulbs replaced and was given a quote of $250. 00 a bulb. The light bulbs had not been replaced. The contact stated that when he turns on his cruise control, the cruise control continued to function even when he tried to disengage the cruise control. The contact had to put the vehicle in neutral in order to disengage the cruise control. The contact also expressed that he had expressed several other failure with the vehicle including other electrical, engine, and suspension issues. The manufacturer was notified of the failures, however, the manufacturer informed the contact that he only had one recall on his vehicle and offered no further assistance. The vehicle had not been repaired. The failure mileage was 40,000. Jo.

Forward collision warning (fcw) occasionally comes on without reason in city traffic,interstates, and country roads (no traffic or obstructions nearby) and at various speeds causing a "brake" warning signal and sometimes, not always, actually causing the vehicle to brake. Related to the fcw problem is a warning signal that frequently appears that indicates the adaptive cruise control/fcw are unavailable. Vehicle has been in shop numerous times and except for one time that the dealership found a part missing, the dealership continues to indicate they cannot duplicate the problem. The problem remains on-going and has not been resolved. The date of occurance below is the most recent event with the "brake" warning.

Tl- the contact owns a 2014 Jeep Grand Cherokee. The contact stated that while driving at various speeds the vehicle would stop accelerating and approximately 20 second later the vehicle would operate as normal. The contact indicated that the warning "electronic throttle calibration" would display during the failure. The vehicle was taken to the dealer who replaced the adaptive cruise control sensor but the failure continued to occur. The manufacturer was not notified of the failure. The failure mileage was 13,500. Jft.

While travelling on open highway with no vehicles in front of me, the adaptive cruise control will dramatically slow down as if it's detecting a vehicle in front. This was reported to the dealer who responded that they would need to take my vehicle home on a 20 mile trip, in rush hour, with cars around them. Unless I let them take my vehicle on a long highway trip, in the early morning hours, this will not be re-produced. I said no for obvious reasons. This is now documented with the dealership and Chrysler.

While driving with the adaptive cruise control engaged the vehicle braked itself hard extremely slowing the car down on the highway. There were no cars in front or in other lanes when this happened. Had a car been following me I would most likely been rear ended. Took the vehicle to the dealer and, after checking out the vehicle, they indicated that they could not duplicate the problem, that the software was up to date, and that the acc system is "working as designed. " this is a major safety issue that under different circumstances could have resulted in a serious accident with injuries or worse.

Driving through the eisenhower tunnel the brake warning system activated. The brakes did not engage. I have had this Jeep for over a year and have driven through this tunnel over 80 times and now whenever driving through the tunnel this brake warning will flash. This has occurred approximately 16 times now. This warning is now going off on the open interstate and secondary roads. The adaptive cruise control stops workings after 15-20 minutes. This has been into two different dealers, only to tell me the lens was dirty. Within 20 minutes after leaving the dealer (who cleaned the sensor) the system stops working and says to clean the sensor. No snow or water was driven through prior to the message being displayed.

The contact owns a 2014 Jeep Grand Cherokee. While driving with the adaptive cruise control activated at 70 mph, the brakes engaged independently. The contact had to depress the accelerator pedal in order to override the system. The vehicle was taken to the dealer, where it was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was 17,200.

Our SUV is equipped with collision avoidance and adaptive cruise control. The vehicle has repeatedly and without cause either alarmed or in some cases slowed to avoid a collision that is not eminent (I. E. Along a straight section of highway with no vehicle or object within sight of the car). The system has provided multiple false alarms and we have not been able to determine a pattern or trigger. Additionally the car reports at times that the acc is inoperable and then moments later the fault message disappears. The car has been taken in for service to address. To date the dealer has been unable to replicate the problem and Jeep is unwilling to replace any parts or acknowledge the problem until it is replicated for them to be able to witness.

Cruise control placed at 55 continually accelerates & speeds up to 80 plus once it crests a hill before down shifting or I have to break hard to slow down and shut cruise off.

1) collision avoidance system engages for no safety reason whatsoever. The 'brake' warning on the dash flashes, the brakes charge, and the brakes engage. I can be the only vehicle on the road and this will occur. Has been happening intermittently each and every day the vehicle is driven. Causes distracted driving, sudden unexpected stopping and unsafe performance of the vehicle putting vehicle occupants at grave risk. 2) after a period of driving time with the adaptive cruise control engaged, the system disengages for no apparent reason. A message alerting the driver to clean the lens is displayed on the dash. The lens is not dirty or obstructed in any way. This occurs each and every time the adaptive cruise control is engaged. Causes unanticipated deceleration of the vehicle, distracted driving, and unsafe performance of the vehicle putting vehicle occupants at grave risk.

I had driven approximately 520 miles enroute to my vacation home and was driving with the cruise control activated and seatbelts were in use by both myself and passenger. Suddenly and at the same time the seatbelt and airbag warning lights came on and within a few seconds the cruise control disengaged and the message "acc/fcw unavailable service required" popped up on the dashboard. For the duration of my vacation the vehicle was operational however I had no cruise control. Contacted two Jeep dealers in the area and they were too booked up to service my vehicle. Upon my return home I took it in to my Jeep dealer. Here is the exact quote from their service invoice as to what was discovered: "found many modules with loss of communications with the orc module (airbag module) with codes in them. Found orc to have an internal fault, replaced and set up orc module".

Trying to set cruise control on 2014 Jeep Grand Cherokee laredo, pushed the set + button to set cruise speed, but would not set. Also tried to just accelerate using the set + button and this would also not increase cruise speed. After numerous times of pushing set + the vehicle would speed up at a higher rate of speed than the one or two clicks. Had to eventually quit using cruise control and it is was unrealiable. Have used in past w/o incident. Had vehicle in for routine maintenance on 8/13/2014 and this was not an issue addressed in any recalls or program updates.

Purchased a 2014 Jeep Grand Cherokee laredo in June of 2013. Have experienced no problems with operation throughout first 10031 miles driven. Departed on extended vacation trip at end of may. After travelling 824 miles, air bag light came on with alarm and dashboard notification advising to have air bags serviced immediately. Shortly thereafter, the seat belt alarm activated with the bell warning, advising that the driver side belt was not engaged, when it was securely set. This condition would continue throughout each driving day. I have now traveled over 3400 miles, experiencing the same annoying, and unsafe condition, including the cruise control now turning off without warning. I have checked with several dealerships, only to be told that this problem could not be identified. There remains 3000 miles to be travelled to return to my home. I do intend on meeting this situation head on through my dealer with Jeep.

Traveling at highway speed numerous warning messages and warning chimes started to go off. Created distractions to driving and it appears that air bag and seat belts stopped functioning intermittently. Cruise control also failed. Vehicle already serviced on all prior recalls two months ago. These issues are new starting on 5/23/2014. Dealer appt is scheduled for 5/26/2014. In past, also reported issues with transmission shifting and hvac. Not a well tested vehicle. Far too many dangerous issues with vehicle. Hope NHTSA can investigate issues.

1. When adaptive cruise control is set and vehicle has to adjust speed, there is a static noise coming from under the steering column. 2. When adaptive cruise control is set, vehicle will accelerate when approaching vehicles instead of slowing down. 3. Vehicle brakes on it's own and displays "brake" in display when more than 3 car lengths away. This happened with and without vehicle adaptive cruise control set. As a side note, Chrysler/Jeep has not been responding to our dealer to rectify these problems.

I purchased a 2014 Jeep Grand Cherokee limited for $46,000 from dothan Chrysler Dodge Jeep ram on Saturday, August 17th, 2013. We drove off the at 8:30 p. M. That evening. On Monday, August 19th, at approximately 4:00 p. M. As I was driving down the highway after having just left my job at the washington county sheriff' office, where I am the public information officer, my vehicles's screen flashed a warning that read: vehicle gear shift malfunction. The screen went completely black for approximately 1 minute. When it came back on the screen read: please service transmission followed by turn off ignition to engage park. I tried to turn off ignition, in the middle of the highway, and the warning then read: vehicle must be in park to turn off ignition. This endless circle continued as I was able to stop the car at a gas station parking lot. I sat in the parking lot of the gas station for approximately 5-7 minutes where I documented (via cellphone camera) the repeated messages and attempted to turn my engine off and simultaneously attempted to put the vehicle in park. The gears would not display. There was no way to see if the vehicle was in park, or what gear it was in at all. After struggling with the vehicle for close to 7 minutes, I was finally able to turn the ignition off. When I restarted the vehicle, the transmission service light was on. I contacted the dealership (as noted above) immediately. I was assured by the salesman that this "happens all the time to Jeeps". This was my first major concern with not only the vehicle, but also the dealership. I have a full team of certified mechanics that work for our office. I met with each of them and was told that this was not a common thing for any vehicle. My cruise control is now completely inoperable.
