2021 Jeep Grand Cherokee

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.

Vehicle shuts down puts itself in park and applies the parking brake and states that the hood is not closed when it is and has not been opened. It also disable the auto stop/start . It does this at traffic lights or when ever a vehicle comes to a stop creating a potential rear end collision due to having to manually restart the vehicle, disengage the parking brake and put the vehicle in drive.

[XXX] just south of Grapevine, CA, is a 4-lane freeway, speed limit 70 mph. It is quite steep, perhaps 4 or 5 %. It is very heavily traveled, and is used by a large number of 18-wheelers. It has a slow lane on the far right, for trucks and cars pulling trailers. I was in the #1 lane, traveling at 70 mph. About 5 miles south of Grapevine, CA, the car completely lost control of the steering. I came within inches of impacting the guard rail, and hitting a large tractor-trailer. By braking gently, and making greatly exaggerated steering inputs, I was able to maneuver to the slow lane, and, driving at less than 15 mph, was able to get to a truck stop parking lot, where the car was towed to a Jeep dealer. This is the third catastrophic safety failure this car has suffered. The first was explosion of the front transfer case, scattering transmission parts all over the road, the second was the failure of the left front axle boot. which spread grease onto the brake disc. Fortunately, both of these problems occurred at very low speed, so accidents were avoided. This last failure almost killed me, my wife, and my little dog.

Upon parking my car in my driveway (which has a slight slope), I put it in park and turned it off. I then opened my door and got out. Before I could close the door my car began to roll backwards and I had to jump back in the car to stop it very quickly. The door was open and got caught on the cement wall that lines my driveway as it rolled back. There is damage to the door and it will likely need to be completely replaced. The next morning I had my friend come over to follow me to a body shop to assess the damage. I reversed my car to the end of my driveway and got out to close the garage door. The same thing happened again right when I stepped out of the car, and I again had to jump back in very quickly to stop it from rolling into the street. I then had it towed to the nearest dealer (on 1/15), where they replaced the vacuum pump because the service stability control light was on. They claim to have tested it on a slope and could not replicate the problem. They checked it out and could not find anything wrong with the transmission either. I got my car back on 1/22 (with the door still needing to be fixed) and this happened again on 1/23. I pulled into my driveway, put it in park, and my car immediately rolled back. I then put my 4-wheel drive on and the parking brake and parked it. It was not rolling so I went inside. I looked at it before bed and it was in the same spot. The next morning I go out to my car and it has rolled backwards down my driveway. Luckily, it did not go into the street. I could have easily been injured on multiple occasions, as well as other people or cars if they were around. The next time I might not get so lucky.

In 2022 I attempted to back into a parallel parking space and the emergency braking system kept activating to prevent backing up. Attempted getting corrected at dealer but no trouble codes available. Was driving, slowing down to stop at about 22mph, emergency braking system kicked in, shifted into auto stick, switched back reactivated normal drive. 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. Luckily car behind me was not tail gating. end of message 04:56-Fri-01/05/24

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.

MY BRAKE ROTORS ARE WARPED,AND THIS CAUSES EXCESSIVE WEAR ON PADS. THERE HAS BEEN A RUBBING NOICE FOR SOME TIME, I ASKED IF IT COULD BE ASSOCIATED WITH THE AUTO BRAKE FOR BACKING UP, THEY SAID NO, HOWEVER THERE IS A PROBLEM AND IT COULD RESULT IN AN INJURY OR DEATH IF IGNORED. JEEP REFUSES TO FIX THIER PROBLEMS THROUGH REASEARCH I HJAVE FOUND A LOT OF 2021 JEEP GRAND CHEROKEE WITH BREAK PROBLEMS LIKE MINE AND IT STARTS IN THE REAR BRAKES SO NOTED IF IGNORED THROUGH THIS AGENCY, I WILL TRACK NATION WIDE ACCIDENTS AND DEATHS .

3 months ago, I was getting my all-season tires installed in lieu of my winter ones. They told me that the lug nuts on all four of my wheels were swollen and I needed to get a replacement as they could not use them. It was my first time hearing this terminology. I asked for clarification and was told that due to severe rust they cannot be used. 15 days ago, i heard some squeaking coming from the tires. I took it to the mechanic and was told that I have to replace the rear wheel pads. I took it yesterday to have them replaced and when they took off the tires, they called me in to witness that the rear disk brake rotors are totally rusted from the inside out, were badly deteriorated, and some pieces were falling off. They checked the front wheels as well, and they had the same issue as well. An issue such as this could lead to severe consequences and could potentially be life threating. I ended up replacing Front and Rear Disk Brake Rotors and Pads, and

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
