2023 Jeep Grand Cherokee: multiple warning lights

Filed Mar 5, 2026 · Brakes, Electrical · NY · crash

On February 28, 2026, while preparing to leave our home with our two children in the vehicle, we experienced a critical vehicle malfunction. Upon attempting to start the car, all dashboard warning lights illuminated, including transmission error, “service needed,” and “automatic emergency braking system needs service.” The battery warning light was also on. The vehicle would not start initially. After eventually starting the car, we temporarily placed it in neutral and pushed it out of the garage, during which the brakes functioned normally. The vehicle was briefly driven and appeared operational, but due to ongoing safety concerns and multiple recalls, we parked it at the top of our driveway. On the following day, the vehicle would not start again. We arranged for it to be towed to the dealership. On March 2, 2026, when the tow truck arrived, the car’s position prevented loading onto the truck. Multiple jump-start attempts failed initially, then briefly started the vehicle, but it immediately shut off again. We placed the vehicle in neutral using the manual override and tested the brakes, which initially showed stiffness but were operational. While attempting to move the vehicle to allow tow truck access, the brakes suddenly failed. Despite pressing the brake pedal fully and brake lights being illuminated, the vehicle did not stop and rolled uncontrollably into our garage. Consequences: •Garage property damage: approximately $11,000 •Personal injury: my father-in-law fell while the vehicle rolled out of control •Vehicle remains at dealership with an open case, but the situation remains unresolved Safety Concern: This incident raises serious safety concerns regarding the reliability of the braking system and vehicle electronics. The vehicle became uncontrollable while brakes were applied, posing a direct risk of injury or death to occupants and others. We fear that similar failures could occur under normal driving conditions, including highway speeds.

There were no warning or check engine lights prior to the incidents below. Car was just serviced Nov 3rd 2025 for safety recall 25v-472 and 25v-576. 1st incident Dec 21, 2025: Driving 70mph on major busy interstate in MA and all of a sudden vehicle lost ALL power. It shut off completely. No lights, No warning. Had to coast over to R shoulder and wait several min before power restored. This was Very scary as traffic was heavy. 2nd incident occurred Jan 19, 2026 and was terrifying: I was driving on a curvy mountain 2 lane road at night. This road does not have much lighting. There are no shoulders or pull over lanes due to guardrails. Out of nowhere with no warning. Vehicle lost ALL power (including steering and ALL lights). Could not get out of road as everything shut off and steering locked. I had NO Lights (both internal and external) I Finally got flashers to work after a minute or so but had to sit there dead in the middle of the road on a curve praying no cars came around curve. Was able to restart after about a minute and a half! Called dealership today and they said there is no recall for “loss of power” and we will be taking it in for a $200 diagnostics test.

I was driving down the interstate with my two babies in the car seats and all of a sudden all of the dash lights came on, and the power steering locked up. I was driving 70 miles per hour and had to pry my wheel as hard as i could to be able to pull over on the side of the interstate. Once I pulled over i turned the car off hoping it would reset whatever happened and the car was completely dead. It would not crank at all. I ended up having to call someone to come get me and my kids off the side of the interstate and tow the car to the dealership. this car has less than 70,000 miles on it and still is not fixed. It has been at the dealership for over 3 weeks with what they are telling me is electrical issues. I do not feel comfortable driving this car anymore as it is a safety hazard and could have gotten me and my children killed.

Two instances: 1) While reversing out of a parking spot, several warning lights flashed at once, including Power Steering System disabled, Service Hybrid Engine System, and two others - lost power steering. I parked and restarted the car and it drove normally. 2) While in park, the car started but would not shift gears and it would not turn off. It was stuck in this position for 10 minutes until the ignition button finally responded and shut off.

Hybrid electric system warning light on while driving with my family on the highway, difficulty with the rear seat headrests, fresh engine oil residue on the underbody. On two occasions, the vehicle remained on and was unresponsive, and all the lights on the dashboard came on, displaying lights and warnings for faults in the hybrid system and battery. It didn't respond when I tried to turn it off. as this may put my safety and that of my family at risk

Was driving at night on a rural highway. Experienced a complete electrical failure - all lights, engine function, power steering and power brakes failed; coasted to the side of the road. ~~I thought that I had just run out of gas, but adding gas did not permit the car to restart. Tow truck could not jump start the vehicle. It was towed to the dealership, where they replaced the regular battery (<20k miles on it), performed the hybrid battery software upgrade (the "recall"), sent me home. Towing and rental coverage were not offered. ~~BTW, I had requested this recall about 3 months previously, but it was "not available" yet. ~~The vehicle continued to stutter intermittently, concomitantly flashing the "service hybrid battery light." I took it back to the dealership. They ran tests, inspected it for unwarranted damage, cleared out the codes, and sent it home. ~~Another 2 months of the same incidents, sometimes with a "refuse to start in the morning" altogether aggravation. I grew increasingly concerned for my safety and the safety of others on the highway. Obviously, this problem wasn't going to go away with just ignoring it and hoping for the best. ~~I contacted the dealership to bring it in for service again; they refused to even entertain the idea of providing me with a rental until they could fix it, even knowing that it's clearly a warranty issue. I took it to a different Jeep dealership, somewhat distant from my home but actually the dealership from which I had purchased it online. They were so kind, got me into a rental and promised to look into it. They got in contact with the manufacturer quickly. Jeep engineering department admitted they can't fix it. 6 weeks later, they still haven't fixed it, I'm paying almost $3000/m for pmt& insurance for a car that's unsafe to drive, but the corporation hasn't offered me any options to get out of a lease.

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.

Since purchase, I have had problems with the U Connect system, which at times renders all communication and some luxury items to be inoperable 1 week ago, car completely had both batteries drain spontaneously . Dealer replaced both batteries with no further explanation. On 5/21, on highway trip, warning lights came on, lane assist, blind spot, ABS stopped working. A/c was blowing hard, but could not adjust. Windows would not open. Hatch would not open, back doors would not open , door lock/ unlock did not work. Could only use handle on inside to open car. Could not adjust side mirrors. Promptly rerouted my day trip back home via side roads and not expressway due to uncertainty of safety. Drove it right to dealer and left the car running while checking in. Car starting flashing lights while service writer was checking car in. Then all lights- headlights and tail lights went dark without touching car. Engine still running. Car is not safe or reliable to drive. Had 12,400 miles and have owned it 18 months. Mostly highway driven by retired couple. 5 th service of electrical issues since purchase.

On 03/24/2023 at 1:30pm I was driving to work on the local streets when multiple warning lights came up on the dashboard.I immediately pulled over on the side of the road to see what was the problem.I decided to look under the hood and noticed the coolant reservoir was empty.I continued checking the engine compartment and noticed one of the hose that leads to the radiator had become disconnected.This was a dangerous situation because if I was on the highway,I probably would not have been able to pull over immediately and the vehicle might have shut down on the highway which could’ve resulted in an accident.I contacted my local Jeep dealer on 03/25/2024 and explained to them what happened.The earliest appointment I was given to have the vehicle inspected was 03/28/2023.
