2021 Jeep Grand Cherokee

Driving through my subdivision, no other cars in sight, no animals, no people, nothing in front of me and the automatic emergency braking mechanism engaged and brought my car to a sudden stop.The brakes engaged on their own, tires squeeled and my body jolted, almost hitting my head on steering wheel. Automatic brake sensors have activated before for no reason as no objects were in sight, but never has the vehicle actually stopped on its own. Luckily I was in my subdivision with no one behind me otherwise someone could have rear ended me and an accident would have occurred with injuries

I was approaching the location where I was about to turn and began to slow down. Out of no where, the forward collision detection system was set off and automatic braking was applied, causing the SUV behind me to go right off the roadway to avoid a rear end collision. Traffic was extremely heavy at the time. The motorist caught up with me at the location I eventually turned into and accused me of slamming on brakes on purpose. I explained to them the malfunction that occured; however, they were still rightfully upset due to them having children in their vehicle, which caused panic. I let them know I would be reaching out to report the situation, as well as turning off the supposed safety feature until the issue could be rectified. This was a very dangerous situation and could have resulted in a major traffic collision, causing serious injury or death. I do have a dashcam video of the incident.

I was driving 45-55mph,closest vehicle was about 4-5 car links in front on me, driving about same speed-when the breaks locked up. I had not hit the break! On my dash where the mph is located it turned red and said BREAK.It made the jeep pretty well come to a complete stop in a second. The seat belt caught my neck,my son (passages) seat belt caught his belt and hurt his stomach, my son (back seat driver side) hit the drivers seat pretty hard. I have now took my jeep into the dealer. No word yet in there findings. This was scary and could have ended very badly. We was fortunate enough not to have wreaked or worse. I don’t know who or where to contact someone about this issue.

I have had TWO incidents where the automatic emergency brake has engaged. The first was in a parking lot at low speed with no cars or objects near the car. The car completely seized up and I had to get a tow truck to take it to the dealer. The second incident I had to slow to zero for a dog in the road and then after it moved and I accelerated the brake engaged and I had to pull out of the road way so I would not get hit from behind. After the car sat parked for 8 hours I was able to drive it to dealer with an engine light on. At dealer the light went off so they were not able to diagnose anything .

Driving vehicle at highway speeds, indicators and alarms started going off saying the power steering, airbags, brake assist, and park sense features were unavailable. I exited the interstate, parked in a nearby parking lot, turned off and restarted my car. All indicator lights were normal, so I began driving again. Approximately 43 miles later, also driving at highway speeds, the same indicator lights and alarms appeared. I exited the highway and tried turning off and restarting the car. Upon restarting, all indicator lights and warning messages stayed on, and the power steering was no longer functional. The car had to be towed to a local dealership.

Forward collision warning system and auto emergency braking system non operative since vehicle was purchased from new. Have paper work from local dealership confirmation that systems are non operative but they can not fix and do not know why. Was told that this is an issue on all Jeep’s. Corporate has a case open but will not call me back and when I call them system states that I can leave a voicemail with my case worker but then hangs up with no options to speak to anyone.

The contact owns a 2021 Jeep Grand Cherokee. The contact stated that while his wife was driving approximately 30 MPH, the Forward Collision-Avoidance system erroneously activated, causing the vehicle to abruptly stop in the middle of the road. During the failure, no other vehicles or objects were nearby to cause the system to be activated. The vehicle was taken to the local dealer who was unable to duplicate the failure or identify the cause of the failure. No service was performed. The contact stated that the failure reoccurred. The manufacturer was not notified of the failure. The failure mileage was 6,000.

Backstory: This vehicle has had electrical issues since the day after signing the lease. The second day of driving the vehicle would not start and flashed all the sorts of engine failures. The dealership could not find anything wrong with it after two weeks and deemed it "repaired." Then, 2 days later the vehicle would not start again and flashed all sorts of of engine and system failures. After 4 months of going through FCA's process for the Lemon Law buyback, FCA presented a buyout offer that was inadequate and contained numerous release clauses we were not comfortable agreeing to. We choose to seek Mass Lemon Law State Arbitration as our right to ensure we achieved a fair outcome. FCA pulled our replacement vehicle and in essence forced us to drive to take back and drive the vehicle after it was again "repaired" this time by replacing a battery. The dealership that repaired the vehicle drove it for a week before we were comfortable taking it back. Incident: A month later, while driving the vehicle on a busy main road (at approx. 15 MPH), the vehicle started to alert that various systems were disable and the transmission started to shift violently and the engine reved. The ABS, airbags, lane departure, powering steering, and other systems said they were disabled and that the transmission was disabled. Fortunately, there was a parking lot on the right, I was able to turn into the lot, and attempt to find a safe place to stop. The parking lot was busy and before I was able to pull into a parking space, the car shut off and would not turn on. The hazard lights would not function, and the vehicle was blocking traffic and multiple parked cars. The car would occasionally start and stay on for 10 to 30 seconds at a time, but either the parking brake was locked or the transmission shifted violently as I pressed the gas pedal. After 20 minutes, I managed to limp the car to a safe spot and await a tow. The vehicle is at the dealership. There is also video.
