2023 Jeep Grand Cherokee fuel system problems

Filed Nov 3, 2026 · Electrical, Fuel system · CA

I am filing an urgent safety complaint regarding my 2023 Jeep Grand Cherokee 4xe Plug-in Hybrid. During inspection, the mechanic discovered that the electrical connector and wiring associated with the fuel pump were burned and melted inside the gasoline fuel tank. The entire fuel pump assembly was subsequently replaced. Before the failure was discovered, the dashboard indicated approximately 110 kilometers of remaining gasoline driving range, but the mechanic found the fuel tank completely empty. The vehicle also experienced engine vibration and an illuminated check engine warning light. The mechanic suggested that operating without gasoline may have damaged the fuel pump. However, the exact cause of the electrical overheating and melted wiring has not been established. I am extremely concerned about the potential fire hazard associated with electrical damage inside the gasoline tank. I request that the federal safety agency investigate the cause of this failure, the accuracy of the fuel level indication, and whether other Jeep Grand Cherokee 4xe vehicles may be affected.

After receiving the 68C update my vehicle has had a constant power drain from the high voltage battery that lessens the advertised mileage in all electric mode. In addition, the power output in all electric mode is severely reduced and poses a safety issue when attempting to merge into traffic or when having to accelerate to avoid a hazard.

On October 23, 2026, my 2023 Jeep Grand Cherokee 4xe unexpectedly lost propulsion. Before this incident, it intermittently shifted very harshly at 40–60 mph while I maintained steady accelerator pressure. That day, a “SERV 4WD” warning appeared and the vehicle tugged and jerked during turns. As I pulled into a parking space, it lost the ability to move. I turned it off. After waiting, I restarted it; there was a very loud thunk, and it suddenly lurched forward. The check-engine and brake warning lights illuminated, and it still would not move. When the tow truck driver restarted it, the loud thunk happened again. He was eventually able to reverse and move the Jeep a few feet onto the tow truck. He said it appeared to be staying in electric mode rather than transitioning to hybrid operation, although this was not a confirmed diagnosis. The Jeep was towed to an authorized dealership. The dealership says diagnostic scans pass and it cannot reproduce the failure. No cause or repair has been identified. My Jeep app shows safety recall 78C (the federal safety agency 25V‑766), related to possible engine failure and loss of propulsion, with the status “Parts Unavailable.” The dealership told me its scan indicates my vehicle does not need the recall, but has not clearly explained why. I do not know whether the recall caused this incident. I have opened a case with Jeep Corporate. I am concerned this unexplained loss of propulsion and sudden forward lurch could recur in traffic and cause a crash. I request that the federal safety agency document and review this potential safety defect.

While driving in active traffic at approximately 6 PM, our 2023 Jeep Grand Cherokee 4xe experienced a catastrophic, sudden loss of propulsion/driving power with no prior warning. The vehicle would not switch to gas, completely died, and refused to restart even in e-Save mode. A dashboard warning appeared: 'plug in vehicle for battery conditioning.' We were stranded in an active lane of travel and nearly rear-ended before securing police assistance (911 call) and a AAA tow. This directly mirrors known safety risks regarding sudden loss of power (Recall 78C / the federal safety agency 25V766) and high-voltage battery failure.

- The high-voltage (HV) battery system and related hybrid control processor (HCP) software — repeatedly, across three separate incidents (Jan 2026 coolant heater/HCP fault, June 2026 front axle disconnect fault, Sept 2026 full HV battery replacement). Also affected: front axle disconnect actuator (drivetrain). Yes, available for inspection — vehicle is at Chrysler Dodge Jeep Ram of Clifton Park. - Recall 68C: HV battery fire risk (owners told not to charge, park away from structures). Recall 73C: possible loss of drive power while driving, increasing crash risk. Recall 20C: head restraints failing to lock, increasing injury risk in a crash. - Yes — confirmed and repair attempted by an authorized Stellantis dealer (Chrysler Dodge Jeep Ram of Clifton Park) on three separate repair orders (RO #106187, #109788, and the current September 2026 visit), with documented diagnostic trouble codes each time (P29BB, C1463, and the current critical HV battery code). - Inspected/repaired by the authorized dealer under manufacturer recall directives (FCA/Stellantis) each time. No police or insurance involvement, since no accident occurred. - Yes — Check Engine Light (Jan 2026, code P29BB), Service 4WD light (June 2026, code C1463), and Check Engine Light again (Sept 2026, current critical HV battery code). Recall notices (68C, 73C, 20C, etc.) were also received separately as advance manufacturer warnings before some of these symptoms appeared.

CRITICAL VEHICLE SAFETY COMPLAINT - CHRONIC MULTI-SYSTEM DEFECTS The vehicle is a 2023 Jeep Grand Cherokee 4xe operating under severe chronic safety non-compliance. The vehicle has an active, un-remedied engine block casting sand contamination fire/loss of propulsion and crash risk (FCA 78C / the federal safety agency 25V‑766) listing 'Parts Unavailable.' It also carries an open side-curtain airbag deployment failure recall (the federal safety agency 26V‑328). Furthermore, the vehicle experiences intermittent climate control and HVAC failures where the heating, air conditioning, and windshield defroster loops completely disable while in motion on the highway. This directly mirrors the safety vulnerabilities detailed in federal recall 24V‑111 (FCA 04B), where faulty hybrid control processor software leaves the front windshield defogger inoperable. When this occurs, the windshield instantly fogs over at high speeds, resulting in an unrecoverable, immediate loss of forward visibility. In addition, temperatures in the summer are between 100 and 120 degrees. Having no air conditioning during this time is a health and safety concern. Dealership technicians state they 'cannot replicate' the issue, forcing me to operate a vehicle that routinely violates Federal Motor Vehicle Safety Standard No. 571.103. Operating this highly volatile hybrid asset on a regular 4.5-hour remote highway commute to act as a caregiver for an elderly parent presents a life-threatening environment. The vehicle is a severe liability threat due to active fire and crash risk, structural airbag failure, and sudden visibility blinding.

Since Nov 2025 there has been a recall with still no remedy for repair. The recall is a huge safety risk regarding the hybrid battery worrying me about it exploding or catching on fire as it warns me to not charge it in my garage and be careful charging it which is the only reason I purchased this hybrid.

At the end of March 2026, the hybrid battery was replaced due to a recall by the dealership. After this, several software updates done, including the BCM, per technician's notes. In May 2026, my vehicle was found bricked in my driveway, unable to jump start, giving warnings regarding the dual charging system. After being towed to the dealership, they found my 12v battery was dead and stated that it needed to be replaced, which was done, with no further testing per technician's notes. Six weeks later, in July 2026, my vehicle was found bricked in my driveway again, giving the same warnings on the dashboard as it did in May. Once towed to the dealership again, with further parasitic testing, they found a "TSB about improper BCM software causing the 12v systems battery to be drained, as well as the kombi flickering which was also experienced while vehicle was in shop. TSB stated the BCM needs to be flashed." (taken from the technician's notes). As the dealership explained it to me, my vehicle failed to receive an update for the BCM, causing this glitch to drain my 12v battery. Due to my vehicle exceeding the 36,000-mile warranty, the dealership forced me to pay for the work done in both May and July, in addition to paying for a rental car while my vehicle was in the shop, even though the cause of this problem originated from the manufacturer, and was no cause of mine.

This vehicle has experienced continuous HV battery drainage since repaired under recall 68C on 2/9/26. Multiple follow up trips to the dealer and discussions with the Stellantis "Star team" have resulted in them informing me the vehicle is unfixable but "safe" to drive. They admit they have no idea what the problem is or how to solve it.
