This letter is to document a serious safety incident that occurred on [xxx], involving a 2025 Jeep Grand Cherokee summit. On that date, the subject driver, was driving a [xxx] child to a scheduled pediatric appointment. While stopped at a red light, the vehicle experienced a sudden and complete electrical failure. The engine stalled and all electronics, including the dashboard display and infotainment system, went completely dark. The subject driver found herself trapped in the middle of a busy intersection in st. Petersburg, florida. Due to the nature of the failure, she was unable to shift the vehicle into neutral or move it to a safe location, as the vehicle’s electronic transmission control was also unresponsive. She was left stranded in this hazardous situation for approximately 45 minutes while awaiting the arrival of police and emergency responders. This incident created a terrifying and highly dangerous scenario—not only for subject driver but also placed the child in danger of heat exhaustion (heat index was over 100 degrees). As a result of this traumatic experience, subject driver has completely lost trust in the vehicle’s safety and refuses to transport the child in the vehicle. We submit this incident as additional evidence of the ongoing and unacceptable safety risks as-sociated with this vehicle. The manufacturer should take swift and decisive action in ad-dressing this matter. Summary service record of the subject vehicle as of July 23rd, 2025: new vehicle - consumer owned for less than 6 months, (4) trips to authorized dealership for service, over (30) days out of service at dealership, stalled in traffic at least once placing the a driver and child in harms way, (2) times the vehicle had to be towed to dealership all service issues have been related to an undetermined electrical failure of the vehicle according the the authorized dealership service repair shop.

While driving my 2023 grand wagoneer the serv 4wd light and dash spelled out service four wheel drive, it lit up the anti collision light, ecs, tcs, and hold!. The parking brake also engaged automatically while driving at least 4 times. This is a serious safety concern to allow a vehicle to continue driving with the ability to automatically engage the parking brake while driving. The safety of my entire family was put at risk. I currently have the vehicle sitting at the dealership to be diagnosed and reproduced as the vehicle lost all power after this incident. Another serious safety concern is the total loss of power with no notice. This could easily have been while I was driving and caused a serious accident and possible fatalities.

Emergency electric brake system has set up a number of times on its own always when it was parked. I was towing the car behind a motorhome ,it is 2024 Grand Cherokee Jeep summit with approximately 6600 miles on it ,the electric emergency break system set up going down the road at 50 mile an hour behind the motorhome. The motorhome has 650 hp engine. I didn’t even feel the brakes set up on the car. I saw a lot of smoke behind the motorhome . I pulled over and it turned out the electric brake set and I couldn’t get it to release. I called the dealer where I bought it to see if they could tell me how to release it. They referred me to Jeep, I thought sure that they’d have someone but they referred me to a Jeep dealer in santa fe, new mexico the dealership had a tow CO haul it to the dealership and told me tow ins were 3 to 4 weeks out before they could get in and look at them . After a month and they had not looked at it I had it hauled to mike shaw Jeep where I bought it. My concern is that had I been driving that car on interstate highways in colorado 75 mph or states where it’s 85 miles an hour and the brake set up I’m going to be in the ditch or in the front of another vehicle killing my self and family or someone else family. This Jeep needs to be taken off the road before someone is killed. I refuse to drive it. Or let a family member drive it. Have had no satisfaction from Jeep dealers. I had to have a car to drive so I had to spend another $60,000 for a car. .

My 2023 Jeep gc overland 4xe was at the Jeep service center for the same issue in a week. I get a service throttle control warning, cel, then every warning light on the dashboard lit up. It happened on my driveway the other day and I would not drive. I had Jeep roadside tow it to a Jeep service center. On 7/9/2025 I picked up the Jeep. Service tec said no open recalls, no software updates and the throttle body module was reprogrammed. A 14-mile test drive was done and the codes did not return. Shortly after pickup, while driving at 65 mph on the thruway, I got the same error message, service throttle control along with a check engine light and all warning lights again lit up. The Jeep displayed a reduced power warning, and many other warning but I didn’t have time to look at the dashboard. The vehicle slowed to a crawl in limp mode at 23 mph, the steering became very heavy and slow to respond. I was able to quickly move over to the shoulder, and I was almost rear ended by a tracker trailer. I got off the thruway, shut the engine off, then back on and was able to get full power back. I immediately drove it to the dealership service center. This is not safe vehicle to be in and there are many other reports of this happening.

Was inspected @ my local garage. The tipm goes out and you lose turn signals, wipers, transfer case control ( locks in low gear) causes airbag light to go on. And Chrysler does not manufacture them anymore. Jeep had to be towed.

Alternator caught fire.

This vehicle continues to have electrical issues which effects the drivability. For the current service visit, the vehicle was taken in due to “shut down” or “shudder off” as if the car had completely been downshifted and lost power while in full drive mode causing a driving interruption. This driving interruption causes a concern for safety. As of today, the vehicle has been in the service department for 56 days. Red wrench appears each time with "service hybrid system", check engine light. Discussions with service department: "no definitive fix" . . •b273c-00 meaning: (one of the codes) the code specifically points to an issue with the digital crash input, meaning the vehicle's computer is detecting a "crash" event, even when one hasn't occurred. •4xe specific: this code is frequently seen on Jeep 4xe models, likely due to the complexity of the hybrid system and its interaction with the orc.

System said car will shut off soon. All system lights started blinking and the car turned off. Car would not restart and would not go into neutral.

Without warning or being given an option to reject the update, my vehicle was updated to settings that no longer offer paddle shifting or the ability to enable or disable the pedestrian emergency braking (peb) system. The latter results in being unable to turn off the forward collision off light on the dashboard. The update also wiped out most of my settings and changed units of measure to the metric system. According to various Jeep owner forums, some dealers have been able to reset something and temporarily correct the issue, but they charge for this service, and the issue returns randomly again. Here is an example forum discussion, indicating many if not all vehicles are affected: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

There is a common issue with wk2 Jeeps from 17-22 where the infotainment screen delaminates due to the adhesive that Jeep used and eventually causes the touchscreen to become non-functional.

While driving a message pops up that says push brake and shift to park and the it shuts down while driving which is a major safety concern. It did it to me twice and could have lead to a significant accident if someone was behind me and if I was on the highway.

The hybrid battery had the potential to catch fire and it was recalled for a software update, the 95b update. After this software update was completed, the vehicle would completely shut down, regardless of being parked or while driving. The dealership deemed the vehicle "unsafe to drive" and has provided a loaner until they can correct the problem. In addition to this, the front suspension has been worked on many times, approximately 5-6 times to remedy a clinking noise when turning at full turn. Currently, they have not been able to remedy this problem. The manufacturer has refused to do a buy back on the vehicle, yet also refuses to give the vehicle back due to, in their words; "it is unsafe to drive".

The contact owns a 2012 Jeep Grand Cherokee. The contact stated that while attempting to start the vehicle, the vehicle failed to start as intended. There was no warning light illuminated. The vehicle was towed to a local independent mechanic to be diagnosed, but the cause of the failure could not be determined. The contact stated that the failure persisted, and the vehicle was towed to another local independent mechanic for a second opinion. The mechanic diagnosed that the fuel pump had experienced a short circuit, and the 150 amp mega fuse needed to be replaced. The vehicle was repaired at the owner's expense; however, the failure persisted. The contact stated that while driving approximately 59 mph with cruise control activated, the vehicle decelerated unintendedly. The contact shifted to neutral(n), but the vehicle lost motive power. The vehicle was towed back to the independent mechanic, where it remained for further diagnostic testing. An unknown local dealer was contacted. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 147,000.

The engine and powertrain are affected by a defect described in safety recall 66a / NHTSA 23v-411 (loss of crankshaft position). Despite the recall software update being performed, my 2014 Jeep Grand Cherokee continues to display diagnostic trouble code p0336 (crankshaft position sensor performance). This issue causes intermittent stalling, hard starts, and loss of engine power, which creates a serious risk of crash if the vehicle stalls while driving. The safety defect described in the recall — tone wheel magnetic material delamination leading to crankshaft signal loss — is still present. Two diagnostic reports (one from an fca-authorized dealership and one from an independent mechanic) confirm the presence of dtc p0336. The service manager at the dealership agreed this is likely recall-related but said fca corporate must authorize hardware repair. Fca (case #93427994) has refused to approve full repair, leaving the safety defect unresolved. The defect has been confirmed by the dealership and independent service center and persists despite the software reprogramming remedy. Warning lights (check engine) are active and the issue is repeatable.

Infotainment system failure while driving and using navigation the system aborts,the screen either blanks out or message "system loading". The radio freezes as well or plays music from a different radio station that driver has chosen. This causes driver to take eyes off from road - which is a safety issue while in traffic. The manufacturer contends that this does not pose a safety related situation. We disagree as have had a near accident as result of system aborting while using navigation and not knowing route when this happens. . . . . We try to reboot system by pushing different buttons which takes our eyes from traffic and road conditions. There have been 8 repair attempts and now manufacturer claims a fix may be out in late September. Nhtsa literature states this condition is "distracted driving"---we completely agree. . . The manufacturer has been working on this issue for 12 months now and says may be another 3 months or maybe longer. This condition is unsafe and we believe a factory mandated recall should be released.

I purchased a 2018 Jeep Grand Cherokee on [xxx] unaware that the vehicle was subject to a federal safety recall and stop-sale order. The recall (NHTSA 24v-838 / manufacturer 94b) was issued on November 7, 2024, for a defect in the abs control module that may disable the anti-lock braking system (abs), electronic stability control (esc), and cause unintended vehicle movement even while stationary. A stop-sale order (vir 2024-11-14) was issued by stellantis on November 14, 2024, prohibiting the sale or delivery of affected vehicles until repaired. Despite this, the dealership sold me the vehicle while the recall was still open and unrepaired. In the months following my purchase, I began experiencing issues with the electronic throttle control (etc). On June 15, 2025, I paid $770 out-of-pocket for etc sensor repairs after a loss of throttle response. The vehicle has not yet been inspected by the manufacturer, but this defect may be linked to the broader electronic issues cited in the recall. No warning lights appeared in advance. I have been driving this vehicle daily without knowing it could malfunction in a way that puts myself and others at risk. I only learned of the recall on June 22, 2025, when I searched the VIN through NHTSA’s database. This has caused emotional distress, financial harm, and a complete loss of trust in the vehicle’s safety. I am seeking appropriate accountability for the illegal sale of this recalled vehicle and want to ensure others are not put in similar danger.

The car keeps dying while I’m driving and saying “shift to park” and then slamming on the brakes and dying. The card is 4 years old with 44k miles. I had to sit on the side of the road in 93 degree heat in florida while pregnant and waiting on a tow truck. How has someone not died because of this? I’ve seen several posts of people saying the same thing happened to theirs. It’s so unsafe.

Vehicle stalls and loses all power while driving. Vehicle comes to an abrupt halt.

Red wrench dash warning comes on alerting an issue with the hybrid electrical system. It has been diagnosed by the dealer multiple times with no resolution and warning it could be related to various emergency systems. This has been ongoing since the potential battery fire software update several months ago. Jeep acknowledges the problem but has no fix for it.

I was driving my 2018 Jeep Grand Cherokee laredo 4x4 on the highway at approximately 65-70 mph, when suddenly the car started sputtering and my check engine light came on and started blinking. The car was essentially not drivable, so I pulled over at a gas station and had the car towed. This is dangerous as I was going uphill, and could have caused an accident, or worse. I did not have a check engine light prior to this! the next day the car was inspected and diagnosed by independent service center, who said there was a cylinder 4 engine misfire, so they replaced the spark plugs and the coils. Car was fixed, or so I thought, fast forward a couple months later while driving to work, same issue (misfires and sputtering) occurs again and coolant now runs low even though there are no visible signs of coolant leakage. I spoke to the independent service center and they mentioned there might be an issue with the engine such as a head gasket or fuel system. I got the Jeep towed to get checked, it was confirmed that it was an engine issue, especially the head gasket, camshaft, pistons, and lifters, and that I was going to need a new engine and it would cost between $8500 - 13000. My Jeep has approximately 83k miles. The issues I describe here with this engine are all similar to those that have been reported.

Was driving in a neighborhood and slowly turning at a 4 way stop, parking brake self engaged causing the car to slam to a stop and was unable to press gas. Had to put the car in park and restart (with shutoff for 30 seconds) before I could move and was stuck sitting in the middle of an intersection.

Driving down interstate going 78mph in hybrid mode and the car shuts off and I was able to get over to the side of the road since traffic wasn't bad at the time. Restarted the car and went on my way with no other issues until last week. Driving down the interstate again in hybrid mode and the "service hybrid " light starts flashing and so I changed to all gas for the remainder of the trip. Took it to the dealer yesterday and they had no answers other then they updated the software. We shall see but how it works but I have my doubts that it wont cut off again or have issues. Only has 14k miles on it when this stuff happened.

As I was driving onto the highway I reached to about 70 mph. The vehicle said “service electric system” on the dashboard and instantly the vehicle lost power and turned off. It then shifted from drive to park without warning as I was still on the highway. I pulled over safely without causing an accident and turned the vehicle completely off.

Vehicle will randomly shut off with "shift to p" message on dash. No warning lights or errors found very unsafe to drive.

Randomly, and without warning, the instruments, gauges, and displays will switch into a language I do not speak or understand (italian). Coinciding with the switch to italian language, cluster and radio display settings revert back to default settings, auto door locks and paddle shifter becomes inoperative (with no menu to enable), pedestrian emergency brake (peb) lamp or forward collision warning (fcw) lamp turns on with no way to disable, units of measurement including speed, temperature, etc. All change, and many other random settings change as well. ***this is clearly a dangerous situation because of all the functions and gauges that change, and the fact it is difficult if not impossible to recover from this due to the language of the setting menus, and the complexity of discovering and navigating through all these changes. I have taken it to the dealer twice, and they say there is nothing they can do and to wait for a possible software update, but none has come and it has been over a year. When this happens, even if one is able to wade through all the settings menus and change setting back, some items cannot be reset (like the fca off lamp).

Multiple incidents of the vehicle displaying a service hybrid system that appears for several seconds and then disappears. Today this occured, the engine abruptly switched to gas mode from hybrid with a sudden lurch, then returned to hybrid mode and the light disappeared . Vehicle has been to dealership twice for the service hybrid system light and no code is stored and they could not diagnose any further.

We were driving our 2023 Jeep Grand Cherokee 4xe and pulled into a parking lot and put the vehicle in park. At this point the vehicle started flashing the battery light and would not turn off nor were we able to put the vehicle in drive. Essentially the entire vehicle was just sitting and running, but was inoperable and we were unable to shut the vehicle off. We left the vehicle running and walked away with our key fobs, but the vehicle would still not shut off. It's a safety issue to have a vehicle running and not be able to put it inn drive or turn it off. We had to call a flat bed tow truck. The vehicle is currently at the dealer and they are not sure what is wrong with it. The warning lamp that came on was the red battery light and auto emergency braking - active braking on was flashing across the screen, but the vehicle wasn't engaged in driving. We have the fob information from when we dropped the vehicle off, but nothing has been confirmed.

While riding vehicle just shuts off and stops. Message on dash states put vehicle in park to start vehicle. Do that and vehicle starts and runs. First time this happened 6/13/25 went one week no problem then on 6/25/25 happened again took to service station no codes thrown.

Sometime after performing the b9a recall (NHTSA 23v-787) repair (my vehicle passed), my check engine light came on. Dealer felt there was faulty airbag orc sensor and this was replaced. Despite replacement the vehicle continues to throw check engine list with error dtc b273c. We opened a star case 6/16/25 and my local dealership kept the Jeep for a week. They stated stellantis said there was no fix available. Still showing check engine light with b273c error despite replacing sensor.
