The contact owns a 2015 Jeep Grand Cherokee. The contact received notification of NHTSA campaign number: 18v332000 (electrical system, vehicle speed control). The contact stated that when the vehicle came to a stop, the vehicle jerked abnormally. Additionally, while driving forward, the vehicle jerked abnormally. The contact stated that an unknown message was displayed on the instrument panel. The contact stated that on a separate occasion, the gear shifter icons and gauge icons failed to activate and function as intended. The vehicle was taken to the dealer and was diagnosed with transmission failure. The contact asked the dealer to complete the recall repair; however, the dealer refused. The vehicle was not repaired due to the cost. The failure persisted, and the vehicle remained at the residence unrepaired. The manufacturer was not made aware of the issue. The failure mileage was approximately 170,000.

Vehicle shut-off while in route, in traffic, check engine light then came on. The second time this occurred, check engine light came on and immediately vehicle proceeded decelerate from 55 mph to 25 mph while I was on a highway. The vehicle would not shift to a higher gear and remained in the lower gear at 30 mph on a 55 mph highway, causing me to move off to the side , turn off the vehicle and then restart the vehicle. Check engine light not shown, vehicle operated, except shifted hard. On several occasions I have shared with the dealer at service appointments that I experienced transmission sensor issues causing delayed shifting, not able to shift into reverse or drive from park, vehicles stalled, and rough gear changes, unusual noises coming from the transmission. The engine check light would come on, then disappear shortly after, but not always. Service appointments by a Jeep dealership resulted in them updating software, which I shared did nothing to resolve the problem, so I brought the vehicle back and asked they check the transmission fluid level and cleanliness of the fluid, and whatever else needed to be checked. I was told the transmission was completely sealed and it was fine by the dealership. It was not fine, and the vehicle stalled again, and again it while on the freeway, almost getting into and accident, the transmission locked up and would not move past 30 mph. A warning light did not appear. I brought it back to the Jeep dealership for repairs because it is not safe to drive. I am being told that the transmission is defective by the service department. I asked if they drove it and they said yes. This has been a problem I have been trying to get resolved for the last four months of 2024. I do have service records, in my glove box, and a video of the transmission flashing in reverse. Vehicle is at the dealership for assessment and repair.

Electronic stability control, check engine and abs lights are all on. This effects not only my esc- I have gone out of control multiple times in bad weather, but because of this the cruise control and the automatic starter on my vehicle do not work either. I live in northern vt where winters are tough. Esc needs to be working properly to prevent potential for crash. I have come close several times this winter to going out of control. Also very annoying that the convenience items do not work. Lastly- these lights have been showing on the dash since last summer. I wanted to trade the vehicle in about this time and still do for a different vehicle but can not because of the dash being lit up. This is causing significant financial impact on my household as the vehicle is depreciating day by day and I would certainly not get what its worth with a dashboard full of mechanic error lights.

My instrument cluster (where the speed, gas level, engine temperature, etc. Is displayed) had completely blacked out. It was periodically coming on. But it's not coming on at all anymore. I've taken it to the dealership, had it replaced (with a used part), had the wiring checked, also tried reprogramming the instrument cluster. Nothing has worked. There was a recall for this same exact problem, with the same exact vehicle except my vehicle was manufactured 3 months after the recall notice called for vehicle manufactured through Aug 2013 my was November 2013. I feel that my vehicle also should've been part of that recall notice.

I received a safety recall letter in the mail. I made an appointment at the south shore Chrysler Dodge Jeep ram service center in inwood, NY for the repair of the recall and to change the oil. I specifically made the appointment for the recall (I keep getting notifications to repair) I went to the service center (1 hour drive from my home) on may 18,2024 (when I called to check in for the appointment “shanty” told me that there’s no appointment scheduled for me, even though I got a text message confirming the appointment) nevertheless, I went anyways. When I provided the recall letter to the representative, he told me that the service team can only do an oil change and can’t repair the defrost that day. So, after waiting for the oil change, I asked when I can come back for the recall repair, the representative told me that they need to get the parts first. I also notified the rep. That my parking rear view camera doesn’t turn on sometimes when in r and sometimes the screen goes black while I’m in the middle of parking. They ended up letting me go and drive with the recall still active. On June 19, 2024, I read on fox business that stellantis is recalling Jeeps due to rear view camera defects. I called the dealer who sold me the car (apparently he no longer works at Jeep) I spoke to a different representative, she gave me the phone number to mopar and stellantis - nothing else. Throughout the entire time of driving this car, I’ve been experiencing total discomfort. The car constantly jerks, seems like it doesn’t have enough power or traction (even though the gas tank is full and charged too) , and the windshield defrost takes a long time to work, even just the other day on June 29,2024 I started to drive and the windshield got so foggy that I had to stop. This car is dangerous and I do not feel safe driving it.

The electronic stability control has malfunctioned and the 4wd svc light has comeon. The vehicle shifts hard when taking off at low speed. When coming to a stop there is a loud pop from transfer case. Also the 4wd low and neutral comes on by themselves. This vehicle definitely has safety issues. I just bought this vehicle and just barely have 1000 miles on it. How is thus safe? the hard shifting started around 6/1/2024 the electronic stability, svc 4wd, going into 4wd low and neutral all started on 6/23/24.

We have a 2014 Jeep Grand Cherokee with a 5. 7l hemi engine. Today on June 14 2024, we were moving slowly in traffic on a street in linden, new jersey, and suddenly the vehicle accelerated by itself. My wife pressed on the brakes all the way to the floor but the vehicle kept jumping forward - the engine was revving and trying to move the vehicle forward while my wife was firmly pressing on the brake pedal. Because we were in stop and go traffic, the vehicle eventually lurched into the car in front of us and caused an accident. The front of our vehicle was damaged as was the rear of the car in front of us. This sudden acceleration has happened a few times in the last 3 years. During the previous instance of this sudden acceleration, on December 24, 2022 we also hit a car in stop and go traffic. The air bags deployed and we had extensive repairs done because of that. This happened another time as well. During that instance, we did not hit anything, and the only way we were able to stop the car was by switching the gearshift to the park position.

The contact owns a 2017 Jeep Grand Cherokee. The contact stated that after driving into a parking space and switching to the park position, while pressing the brake pedal the vehicle suddenly experienced unintended acceleration and crashed into a building. The driver immediately switched the transmission to the reverse position and the vehicle again experienced unintended acceleration while pressing the brake pedal and drove in reverse at a high rate of speed crashing into two parked vehicles. During the incident the air bag did not deploy. The driver sustained a concussion and neck injury which later required medical treatment. The vehicle was destroyed and towed away. A police report was taken at the scene. The cause of the failure was not determined. The local dealer was notified of the crash but no assistance was offered. The manufacturer was not yet contacted. The failure mileage was 67,500.

The engine would randomly accelerate , rev and make a whining noise, slip into neutral and I would have to pull over and shut it off sometimes in an unsafe area. Occasionally when I would start the engine it would rev as though I had my foot on the gas and I would shut it back off. I was traveling on the highway approximately 70 mph and cancelled the cruise control to go around a curve and pressed on the gas to merge into 70 mph traffic on another highway, and nothing happened. When I got to the end of the ramp the car was going 32 mph with my foot to the floor on the gas panic stricken. Suddenly the gas engaged and I shot into the traffic trying to avoid me. I took the car home, parked it in the garage and called a local dealership for service explaining the problems I was having. I went to resume my trip in a friends car because I was frightened to drive mine. While I was away my partner went to move the car a few feet to get to the trash barrel and when he put it in reverse the car shot 8 feet at high speed out of the garage and hit a tree. He went to the hospital and the car was taken on a flatbed to the dealership where I purchased it. There is considerable damage. The acceleration problem happened at least 15 times and I have several adults that were in the car and witnessed it. Chrysler did the diagnostics and said there is no defect. I would never attempt to drive the car again and if I traded it in then an unsuspecting person could be hurt or killed in it.

Vehicle acceleration stops at high altitudes which causes the vehicle to suddenly maintain lower gear and speeds while driving on interstate/highway. Vehicle had accelerator replaced by delearship at 1,406 miles, however the issue continued. Dealership is now replacing turbocharger engine after reporting failure at 3,500 miles.

Vehicle immediately accelerated as I was attempting to pull out of the house garage. I pressed hard on the breaks to halt it. I then returned the gear knob to park (“p”) mode. I tried again to place the gear knob on drive and the vehicle started raving on high as if it was about to take off at full speed. I waited for a few minutes while it was on park “p” mode, with the engine still idling, and placed it in reverse “r” mode to return into the garage and the same thing happened in reverse mode. It jumped back in full speed when I gradually released the brakes. Engine was raving extremely high. I decided to shut it off and schedule an appointment with the dealership for a vehicle inspection. As is, not certain if it might do the same while out on the street driving it. Vehicle just had a recall inspection done on 4/20/2024. This is the first time the engine has done such.

Car makes loud humming noise when accelerating and safety break go off for no reason when backing up or parking . I try put gas’s but it doesn’t let me keep the nozzle in . Gas’s light always going off.

I am experiencing 2 issues with the vehicle. 1. I am not sure exactly which component is affected, but on several occasions I have had the car essentially stop responding while I"m driving. While driving on the highway, the car somehow loses response, I don't know any other way to describe it. It's almost like the car switches to neutral, but the gear indicator still says it's in drive. Pressing the gas pedal does nothing, the car just continues to glide along, steadily slowing. On these occasions I have had to pull over to the breakdown lane, nothing in the car responds, changing the gear does nothing, I have to shut the car off to kind of reset it. After a few minutes you can turn the car back on and it runs fine. 2. The display screen for controls, radio, etc. . . Is black. The dealership tells me this is a widespread issue and the replacement radio units are not available. This has been going on for 3 months. No back up camera, no phone connection, no control over the display, nothing. I can't see the temperature or the mode beyond the actual buttons on the dash. At one point the dealership advised that they had received a radio and after waiting all day to get it back they told me it was dead in the box and they have no eta on another one. During the first troubleshoot for the radio, the car was returned to me stuck in spanish or portuguese and they have not been able to get it out of that mode. So I currently get a warning numerous times per day but I have no idea what it's warnign me about, and the odometer is stuck in kilometers. (I truly believe they were bs'ing me about even having it in the first place after all the stringing along and lying they've done. ) as of today, I have no eta on a fix, and neither the dealership or the warranty company is able to provide any information.

I am driving on the highway and my vehicle goes into neutral on its own it’s very dangerous and almost caused an accident from what I was reading there was a recall for the software for the transmission this happened quite a few times and needs fixing.

Many engine related problems. Have proof of related problems and/also I have prof of me repairing the vehicle my self in present day.

Nhtsa recall # 23v-411 (fca#66a) was performed, but did not fix the issue with lost power. Even though the recall "fix" didn't work, fca said that the proper fix wasn't covered, because the vehicle isn't under warranty. According to the dealership, the tone wheel needs replaced, and they said fca should cover the cost.

On Jan 17, 2024, at 5:39 pm, I was driving the vehicle in electric save mode, where the temperature was around -19 degree on that day and I was heading for car wash, during that time, the vehicle in front of me applied a break. I was at safe distance I applied the break as the distance was close even the anti-breaking system did not work on hitting the vehicle at that time, and then it bummed three times. I was in shock at the vehicle's behavior and lost confidence in it. So the police office impounded the vehicle. To make the road safe. None of the air bags were deployed. I am having trouble picturing what would happen if this were on the freeway.

Radio not turning on at all.

Started engine and had no power steering plus all warning lights on dash.

While driving, all the light on the dashboard come on. When this happens the speedometer is not working the windshield wipers come on. The emergency brake light is on, the car shifts out of gear and the turning signals don't work and the hazard lights won't work. This is all happening at the same time. I'm unable to inform people on the road that I'm in distress because my hazard light won't work I don't know how fast or slow I'm going. I can't inform the people on the road that I want to change lanes. Then after a while all the lights on the dashboard would go out and the check engine light would remain on for maybe two days and than go out. This problem has been going on since January I have paid thousands of dollars attempting to get this problem fixed. My car has been back and forth to the same Chrysler central Ave dealership where I purchased my 2018 Jeep Grand Cherokee to which I'm still paying for.

I rented a 2023 Jeep Grand Cherokee at our local airport (monterey, California) and drove it to los angeles and back for a total of about 700 miles over four days. I am an experienced driver and have been working on cars all my adult life. On several occasions, I attempted to the use the cruise control function to set a fixed speed for my journey. In doing so, I would first turn cruise control on, accelerate to the desired speed, then momentarily press the set button, at which point the vehicle would 'remember' my current speed and maintain this speed indefinitely. Nothing unusual about this, and it's how I've used cruise control in multiple cars over the years. Now, as in a lot of cruise control systems, one may use the set button to cause the vehicle to accelerate, instead of pressing on the gas pedal. This is also a common way of doing things. One holds down the set button, the vehicle increases speed, and once the vehicle gets to the desired speed, one releases the button and the current speed is maintained. But not in this Jeep Grand Cherokee. Instead, I found that if I pressed and held down the set button for a few seconds that the vehicle would continue to accelerate long after I had released the set button. For example: traveling at 75 mph, I held the set button for two or three seconds and released it. The vehicle began to accelerate at about two seconds, but continued accelerating for a period of twenty seconds, until I finally stepped on the brake, at which time the vehicle had reached 91 mph. In my run to la and back, I tested the system several times. In the above example, I used my cell phone to make a video recording of the event. I'm glad to share this with NHTSA staff. My general belief is that this is not a one-off defect. It is the way the system is designed to behave, and it's unsafe. There are a few comments on the web pertaining to 2021 & 2022 Jeep products that support what I have said here.

It is easy, when driving in automatic mode, to accidently touch one of the paddle shifters. In doing so, the automatic transmission disengages, and the transmission suddenly switches to control by the paddle shifters. If the driver is unaware of this, the vehicle can lose motive power if the gear then in effect is no longer fitting for the vehicles speed and the engine's rpm. I recently took the vehicle in for service of this issue because my wife had experienced this while driving on interstate 95, in maryland. The vehicle stopped responding to the accelerator, so she pulled onto the shoulder, put the vehicle in park and turned it off. When she turned it back on, it was back in automatic mode, and she was able to resume driving. The technician and service manager advised that when this occurs, the vehicle can be returned to automatic mode by pulling the right paddle forward. That information does not appear in the vehicle manual, or on the Jeep website. The technician and service manager also advised that there is no way to disable the paddles to prevent the problem from repeating, other drivers have experienced this. . Read more...

Our car was stopped and then engine started intermittently lunging forward for no reason. Rear ended the car in front of us and had to use the emergency brake to stop the car. Jeep corp sent an independent inspector to check the car but only shared the car was drivable and didn't say there was a problem. They wouldn't share the computer findings with us or the dealer, only that is was drivable. They also wouldn't allow the dealer to see the computer while it was being tested. The car is currently parked and we bought another car. Waiting for Jeep to cover replacing parts or do something to the Jeep before it has another accident.

The problem happens intermittently and not all the time. I will be driving on the highway or in the city and sometimes when I barely touch the gas pedal my car will accelerate at high speeds, and the rpm gauge will go all the way into the seven mark and it turns red and it starts beeping and the only way to get that off is for me to let off the gas pedal and come to a stop and then shift it from drive to park and then that’ll usually fix the problem. And other times when I’m on the highway. I will barely touch the gas pedal and it’ll accelerate at high speeds and I’ll have to go from the gas pedal to having to slam my brakes on to avoid hitting the vehicle in front of me. A friend of mine who had driven my vehicle, called me and asked me if I noticed that it was doing that as well and I explained to her that I I was aware. I have not taken it to the dealership yet for that problem yet however, I do have an appointment made. I’m just waiting on them to find me a loaner vehicle that will seat my six person family because I cannot drive a different vehicle that does not fit my whole family .

I was driving on a road when the car suddenly accelerated for no apparent reason. I hit the brake and nothing happened. When the car accelerated, it was like when you hit resume when you have cruise control on. I did not have cruise control on. To avoid hitting a vehicle in front of me, I went off the road to the right, hit a chain link fence and stopped in a field. The car was declared a total loss by the insurance company. Earlier that day, the car was giving me a warning to brake, when I was not near another vehicle. On other occasions before this, the car would tell me to put my hands on the steering wheel when I was gripping the steering wheel.

We had two tires put on/rotation at the dealership and the two recalls repaired via a software update on or around the end of August. Once I left, felt the steering was hyper sensitive thought it was the tires. I had two incidents upon acceleration the truck aggressively yanking me into the opposing lane without driver input. Secondly, my wife had it happen to her on a very busy feeder road, the truck not only aggressively pulled her into the adjacent lane but also accelerated. I was told the software update corrupted the electronic steering input and the electronic steering gear resulting in the car 'getting a mind of its own'. I followed up with stellantis about a buy back or swap and was denied. I do not feel safe in the vehicle at all. It literally feels like a passenger is yanking the wheel out of your hands. Very dangerous. My truck is still in repair awaiting parts. Stellantis tells me that after the dealership service department issues a report, they may reconsider. I find it deeply troubling.

While driving 70mph on highway, all lights on dash illuminated, lane assist malfunctioned, wipers went on, blinkers stopped working, vehicle lost speed quickly. Was able to move it off the road, but stopped running before being completely on shoulder. Vehicle would not turn on again in any capacity and hazard warning lights would not function. Needed to have vehicle towed, awaiting final report on issues. No warning was given before this malfunction occured.

The contact owns a 2018 Jeep Grand Cherokee. The contact stated while driving 35 mph, several unknown warning lights illuminated, and the vehicle started hesitating and then stalled. The vehicle was towed to an independent mechanic, and the mechanic had the vehicle towed to the dealer to be diagnosed. The contact was informed that the throttle body needed to be replaced. The throttle body wiring was replaced, and the codes were reset. The vehicle was taken back to the dealer, and it was suggested that the vehicle needed to be retested. The vehicle was repaired again. The contact stated that after retrieving the vehicle from the dealer, several unknown warning lights illuminated, and the vehicle accelerated independently while depressing the brake pedal. The contact stated that the vehicle stalled while coming to a stop. The contact made a left turn into a parking lot and the vehicle independently accelerated. The contact stopped the vehicle and had the vehicle towed back to the dealer where the vehicle was being repaired. The manufacturer was notified of the failure and a case was opened. The approximate failure mileage was 25,000.

While I was driving with my family on a highway, I deployed the drive assist function that controls the speed of the car and keeps car in lane, out of a sudden the car itself deployed a sudden quick brake without any immenant risk in fron of me ( there was no car in front of my car for at least more than half a mile) this caused a very close threat from being hit by the cars behind me amd all of my family members to be scared and worried and even my wife blamed me for slamming the brakes without any reason. I have scheduled an appointment with the dealer in the coming weeks to have it looked at and fix a recent recall as well as look into another weird noise/sounds that I was complaining to the dealer about in the past but was unable to fix or replicate.
