Similar to NHTSA ids#: 10533622 and 10533524. Occurrence: 5 times to date frequency: Randomly speed: Less than or equal to 50 mph each time adaptive cruise control: Always off, never on vehicle mileage: ~ 3,200 the car randomly applies the brakes even though there are no objects in the road (front, rear or sides) and no pending accident. Out of the five times, two of those times so hard that the anti-lock brakes activated. This is very dangerous and can cause an accident. To date no accidents, because no cars have been around when this happens. I have a family and am afraid to continue to drive or let them drive this vehicle. It has been to the dealer once for this issue and will now go in a second time because the issue was not resolved. The ntsb should really look into this issue with Chrysler and either issue a recall or at a minimum issue a tsb.

First instance: At vehicle startup, electronic gauge cluster immediately posted "service immediately" warnings for ABS, air bags, 4X4 suspension, parksense, among others. Speedometer was not operational. Unsure if blind spot monitoring was operational. Check engine light remained on. Turning off ignition, opening doors, and waiting several minutes did not clear the issue. After waiting overnight, everything was operable. At first service visit, dealer reconfigured PCM per Chrysler and returned vehicle. Second instance: Approximately two weeks later, the above issue recurred. We could not make it to the dealer and had to drive the vehicle in this condition. A few days later, the issue recurred once more. This time, we were able to drive it to dealer. While service was closed, we asked someone to verify the condition and download codes. We contacted Jeep customer care and was assigned a case manager. At service visit, the dealer stated they were unaware of this ever happening, and I told them I had seen several cases on Jeep internet forums of an ABS module being replaced. After speaking with Jeep, dealer installed new ABS module. Also, we were given a rental Chrysler 300C for one day during this visit, and it failed to start the morning we had it due to an apparent electrical issue and had to be towed from our garage. Just two weeks after the Jeep had the ABS module replaced, we have yet to see recurrence. However, when I asked Chrysler case manager if all systems displayed as needing service during this issue were truly mechanically working or not, she said they "probably" were. When I questioned that response, she stated the best thing to do would be to pull over and have vehicle towed if it happened again. She would not confirm that other vehicles had a similar issue or if the ABS module fix was successful in those cases.

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 vehicle'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 Jeep". 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.

The better business bureau has pointed me to you all as you can see in the response below: This message is in regard to your complaint submitted on 6/17/2013 6:08:54 pm against Chrysler group, llc.

Therefore, the BBB will close this complaint and not pursue it further. For next steps, please contact the NHTSA at www.NHTSA.gov for more information." To sum up the issue, I have the autobraking functionality turned off and the vehicle will sporadically brake on its own when approaching another car/object as part of the anti-collision warning system. Chrysler give the option of turning the braking off or on, and I have it set to "off" but there is no solution as they cannot now duplicate the problem (it's sporadic). I used to be able to replicate the problem with other technology errors I was receiving and they fixed the issue initially, but it's now sporadic.
