What 397 owners told NHTSA about the 2021 Jeep Grand Cherokee Trackhawk

I was driving north on I64, and a car in front of me suddenly stopped. Cruise control was on, but when i applied the brake, my car did not stopped, and cruise control speed up, before decreasing speed. Instead of turning off, and allowing the car to slow down. I had to swerve, causing to go off on the side of the highway, and held my foot on the brake for almost a mile, along the side of the highway, before the car came to a stop

For my 2021 Jeep Grand Cherokee, the Antilock braking system, Hydraulic control unit has failed. It is currently being repaired by the dealership, and I will request the old part so that it is available for inspection. The failure of the ABS control unit, disabled the electronic stability control, the forward collision warning system and the cruise control - and the issue appears to be directly equivalent to the current Stellantis recall for Ram 1500's of a similar year. The dealer was able to reproduce the error - and was inspected at a Jeep dealership.

Frequently all lights go on while driving check engine goes on here and there on the highway. Loud noise when you start the car and continues for about 2 min after the car is turned off as well.. All lights went on and was unable To move the vehicle in the middle of a street. I have taken the vehicle in several times to 2 different dealers and I am told there’s nothing wrong with it. It’s a danger to my family and I for the car to continue to do these things as the car is unable to be moved..

Six months later, was at a stop sign, on green light, turned left from left lane, accelerating to approximately 25mph, suddenly emergency braking activated again, again had to use auto stick to kick out of emergency braking.

On many occasions, warning lights come on for no reason. The dealer has "updated" software, but to no avail.. Collision warning, stop/start error, throttle body error and more. On the last event we were driving uphill, approx 25 mph, nobody in front of us, and the brakes slammed on with multiple errors showing.. the car then lurched forward with active breaking, stop start error, throttle body sensor all showing up and going away. This happened 4 times on the evening of Sep 15th. The errors and random and intermittent.. They replaced a "secondary" battery at one point, and that did nothing. They told us we needed to drive it for over 100 miles, to charge the battery, but it did not fix the stop/start or any other error. Now it is in the Cerritos dodge dealer and we have a formal complaint filed with Chrystler.. The dealer states they can't find any problems.. During most of the events, the errors and warning lights do not stay on longer than a few seconds. I have one picture I was able to take when the warning lights stayed on a little longer.

Crossing 4 way intersection with no cars or animals in site and while accelerating at about 40 mph vehicle came to a shuddering halt in the middle of the road for no reason. My husband and I were both thrown forward whipping our necks back and forth and my collar bone taking a direct hit with the seat belt. There were no sounds to warn us, no lights came on it just slammed its own brakes for no reason. My dealership brought me a loaner and vehicle was towed to them where they are working on getting the issue solved, but I am going to be terrified this will happen again and rightly so.

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.

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.

Purchased new 2021 Jeep Grand Cherokee L Overland in December 2021. The SUV has 2900 miles on it. Since purchase, the auto park engages at random moments most recently today when pulling out of drive thru lane. I began to drive the jeep forward and it locked up and engaged park brake. This has happened on numerous occasions. I went to get in the Jeep a few days ago. Started the engine and the brake engaged itself before even putting the vehicle in reverse. The touch screen in the dash that controls all functions of the SUV including radio, car play, heat/cooling, vehicle settings will randomly shut off and go black while traveling. While using the paired phone setting when making a call, the speakers produce a swishing/scrubbing sound that will not stop while the call is in session. New today, the windshield washer fluid light is on and the fluid is full. Due to "staffing shortages," can't get the Jeep into the local dealer until March 11th to be examined. Such a joke for a $60K vehicle.

The power steering icon lit up on the dash saying to bring it in for service. Tbe steering felt labored. The vehicle had under 2000 miles on it. After driving around for about 30 mins and then turning it off and going into a store I css as me out turned in the vehicle and all was fine again. The lane departure icon also said it was unavailable. This seems to happen when the temperature is cold outside. There was also a yellow icon that looked like a car crash that lit up on another night and said to bring in for service emergency braking was unavailable. These is quite unnerving gvyo happen in a brand new vehicle. I have read of many others having similar issues with their grand Cherokee L

The automatic braking system/parking collision system on our vehicle regularly causes it to slam on the brakes when the vehicle is in reverse, despite there not being any objects anywhere close to the vehicle. We have had this occur when we are trying to get out of oncoming traffic into a parking space, move out of the way of oncoming traffic into a driveway or parking garage, and when trying to back the car out of oncoming traffic to avoid a collision. This problem has been inspected by, and reproduced by, the dealer (Dishman Jeep in Spokane, WA). No other individuals have inspected the components causing this issue. There were no other warnings or symptoms of the problem before they appeared--just the slamming on of the brakes in reverse accompanied by a loud noise and message on the dash about potential collision, despite there being no objects or people anywhere close by.

I took my vehicle in for a recall on Saturday. I left with the auto start stop warning light on. They said the cable was fried and part was on back order, otherwise it was fully drivable. I started it for this first time since Saturday on Monday morning. I began to drive and the AEB immediately slammed on. Every warning light started to flash. Including the hazards. I had to unload my kids through the driver side, as the other doors wouldn’t open from inside or outside. The locks nor the windows would roll down. On the suspension it said to turn the engine on, however the engine was on.
