2014 Jeep Grand Cherokee electrical problems

ELECTRICAL SYSTEM

The vehicle has a severe, life-threatening safety defect where it randomly drops into neutral while driving at speed, physically locks the shifter, and actively engages the electronic braking system on its own, stranding me in active traffic. I brought the vehicle to a certified Jeep dealership to resolve this exact symptom. They misdiagnosed the vehicle and charged me nearly $3,000 to replace the valve body and connectors. The dangerous symptom remains completely unchanged, meaning the vehicle is unsafe to operate and the manufacturer-certified repair facility has failed to remedy a critical safety defect. The issue hasn’t been fixed and it has been 5-6 months.

My 2014 Jeep Grand Cherokee suddenly developed a no-start condition after previously operating normally. The vehicle would crank but would not start. The battery and fuel injectors were checked and replaced as needed, but the problem persisted. Based on the symptoms and known issues affecting 2011-2014 Jeep Grand Cherokees, the internal fuel pump relay/TIPM is suspected. This defect has been the subject of previous safety recalls because it can cause engine stalling or a no-start condition. Although my vehicle is not currently included in an open recall, it is experiencing the same type of failure. A failure of the fuel pump relay can leave a vehicle stranded or cause the engine to stall unexpectedly, creating a serious safety hazard if it occurs while driving. I believe this issue should be investigated to determine whether additional vehicles should be covered by the recall.

My Son just bought the car from a private party. On our way home the engine light and a lightning bolt icon illuminated on the dash, followed by the vehicle going into limp mode. We had the vehicle scanned for codes and it came back with P0336 (crankshaft position sensor performance). After much investigation online, we found out that this is a known issue with the crankshaft position sensor and, most importantly, the tone wheel on the back of the engine. We looked up recalls on the vehicle and found a safety recall had been issued. While some vehicles affected received replacement of the tone wheel and sensor, others just received a software update. This particular vehicle received the software update. The issue is that the magnetic material on the tone wheel delaminates from the tone wheel. This is a costly repair that should have been fixed correctly from the beginning, not just a software patch. It is a safety concern because it is dangerous when you are traveling at highway speeds and it goes into limp mode.

While driving on the highway my Jeep GC shifts into neutral. Once I'm able to pull the car over, I'm not able to put the car into park or shut the car off. After a bit of time the car will start back up and will drive. It has been to the shop and they can not find what is the problem. there are no codes to be read. In reading various forums that is a common problem with the 3.2l engine in the Jeeps. It is dangerous as you lose ability to drive the car on teh highway, when it happens and hopefully you are close to the left lane so you can pull over without being hit.

ELECTRICAL SYSTEM

While driving home from work on March 13, 2026, the alternator in my 2014 Jeep Grand Cherokee (3.0L EcoDiesel) failed, resulting in a progressive loss of electrical power. As battery voltage dropped, the vehicle entered “limp mode.” When I was aproximatly 1 mile from my home when I was forced to stop at a railroad crossing while a freight train was passing. At that time, due to low voltage, the electronic shifter and ignition system became completely unresponsive. I was unable to shift the vehicle into Park or Neutral and was also unable to shut off the engine. The vehicle remained in Drive, requiring constant brake pressure to prevent forward movement. This created an immediate and dangerous situation, as I was stopped very close to a moving train with no functional means of securing or disabling the vehicle. Any loss of braking force or control could have caused the vehicle to enter the path of the train, creating a high likelihood of serious injury or death. After reaching my residence, the condition persisted. I remained unable to shift or shut down the vehicle and was forced to manually disconnect the negative battery cable, which is located under the passenger seat, in order to stop the engine. I am very lucky that I had a small metric socket set in the vehice, that I am somewhat mechanically enclined, and that I have long arms & legs, as this process was extremely difficult. I had to disconect te battery cable while maintaining my foot on the brake to avoid crashing into my garage. The vehicle appears to be designed such that engine shutdown is not permitted unless the vehicle is in Park, while the electronic shifter becomes inoperative during low-voltage conditions. This combination creates a hazardous failure mode in which the driver cannot place the vehicle in Park or turn off the engine during an electrical failure. This incident appears consistent with hazards identified in NHTSA Campaign Number 16V240000 (Recall S27). Despite records indicating that rec

The Anti-lock braking system and the electronic traction control system are both failing. There were previous recalls on both systems that say they have been repaired, but the lights for both are constantly on. The brakes do not work fully, and it has caused me to slide down the street from my workplace. The electronic traction control system not working has caused it so that my four-wheel drive does not work, and I have gotten stuck in the snow multiple times. The car has been inspected by a repair technician. The warning lights came on right as the problem was happening.

Several of these issues involve systems that are critical for emergency safety, braking, and vehicle control. Dear NHTSA, I am submitting this complaint because my 2014 Jeep Grand Cherokee Limited is experiencing multiple safety-related failures that I believe are part of a wider defect pattern affecting this model year. Several of these issues involve systems that are critical for emergency safety, braking, and vehicle control. ⸻ 1. Telematics Control Unit (TCU) Failure Causing Loss of 9-1-1/SOS Emergency Function My Jeep is displaying repeated “Service Emergency Vehicle Phone” errors and the SOS/911 emergency button no longer functions. This is a major safety concern, especially in the event of an accident or breakdown. The TCU failure also causes: •Uconnect 8.4 system not booting •HVAC controls becoming non-functional or unsafe (blowing incorrect temperatures, failing to defrost, turning off unexpectedly) •Random system resets •Loss of ability to control climate during driving (creating visibility issues in cold/wet weather) These issues align with widespread failures of the Uconnect 8.4 / TCU hardware on 2013–2015 Grand Cherokees, which were not included in a recall despite many vehicles exhibiting the same dangerous symptoms. ⸻ 2. TCU-Related CANBUS Interference Causing Transmission and Drivability Safety Issues When the TCU fails, the vehicle experiences: •Transmission communication errors •Vehicle entering limp mode unexpectedly •“Service Transmission” and “Press Brake to Shift” warnings •Delayed or unpredictable shi

My TCM (Transmission Control Module). Yes. While driving my jeep kept shifting into Nuetral all by itself and I would have to shift back into Drive. This is going into my jeep dealer on 8-5 and put on the diagnostic test. It was only checked out by plugging in the meter and this is the code that came back. Has not been inspected by police, insurance, Jeep dealer as of yet until 8-5-25. Yes it went from shifting g into Nuetral by itself to Slow g down on its own and it happened most recently on a major interstate with an 18 wheeler behind me and almost rear ended me. As I gave it gas it wouldn’t go I rolled to side of road. This was the 5th time this happened to me. It all started back in beginning of July. The check engine light came on.

ELECTRICAL SYSTEM

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.

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 was driving home from dinner and while driving I got a notification on the dashboard and then few moments later it locked up and everything started turning off. Incuding the radio, AC but not the car. The car would not drive once I got it on the side of the road. The car would not turn off due to not being able to place car in park. It was stuck in drive. My husband had to come over and put his foot on brake and take over the wheel. He then hit the power button for 5 seconds and it went into park and turned off. We called a tow company to take it to dealership to get fixed. We seen we had some recalls so we asked if that was the issue they said yes and ordered parts to fix. Days and weeks went on got car back and when I drove home my car I will say does not feel safe for me to be in nor be on the road. I had smoke inside my car where battery is when on side of road which one day will be where my kids are. Also they said nothing was wrong with alternator but when on side of road I could smell burnt alternator. They said was fine and recall wasn't needed. I do not feel safe at all nor does my husband feel safe driving the car. Dealership we bought from never told us about the recalls when we bought in 2020, and now this dealership saying it doesn't need to be done we do not feel the car is safe to be on road and will be fire hazard down road.

Fuel pump failed. Electric control module/system failed. I have been having these problems since 2021. When it first started my car stalled out, completely died, and started rolling (even though I was pressing the brakes) - I had to pull my E brake and luckily stopped an inch away from hitting the car in front of me coming to a stop because the light turned red. My entire car shut down. I had to get a tow. I took it in to a shop and they had no idea really what happened or what it was. They told me a bunch of stuff was bad (thousands and thousands of dollars worth of stuff) and I ended up only getting whatever was absolutely necessary which was the fuel pump and battery. $1300 later it was driving at least. Ever since then my gas gauge has NEVER been accurate and just goes up and down randomly. I have to track my gas by resetting the miles of my “total trip” when I fill up. My dashboard constantly went on and off and I never knew what was accurate and what wasn’t. About 6 months ago my dashboard went completely black and hasn’t came on since. My car is now barley taking over 4 gallons of gas at a time before the auto stop on the pump cuts off. If I try refilling anyways gas overflows. This makes absolutely no sense. I can’t see how fast im going, hear my blinkers go on and off, see how much gas I have, how many miles are on my car, any check engine lights, and now I can’t drive over 75 miles without having to “fill up” my measly 4 gallons again before the pump shuts off. I was never notified of any recalls but there is absolutely no way my car is excluded from them. The electronic control module is fried, I can’t even get gas, and a brand new battery and fuel pump was clearly just a miniature band aid on this disaster chain of problems. I’ve only had this Jeep for like 5 years too and what it’s worth is not even worth a fourth of the cost it would be to fix all of this.
