Dealer illegally refused to complete recall repairs. Lakeshore Chrysler Dodge Jeep Ram Fiat located at 330 E Howze Beach Rd Slidell, LA 70461 refused to complete recall repairs for manufacturer recall 66A, the federal safety agency recall number 23V‑411. While traveling for work out of state the vehicle suddenly died and would not start due to the loss of signal for the crankshaft position sensor. this happened late on [XXX] and transportation could not be arranged until Friday. The vehicle was trailered and brought from Texas to the Slidell dealership on Monday June 9 2025. The service department informed us they did not do recall repairs on the EcoDiesels unless they had sold it to us directly. They said this was because it takes too long to do the repairs and customers get upset over the wait and that they did not want to loan vehicles for extended periods of time not knowing how long it would take to complete the work if parts were back ordered. We had to have the repairs completed at an independent repair shop and paid out of pocket for the repairs and the transport of the vehicle from Texas to Slidell, Louisiana where we reside.

The alternator failed. It was the Safety Recall P60 (the federal safety agency 14V‑634) remedy alternator, installed by an authorized FCA dealer when the recall was completed on 08/30/2021, as FCA confirmed in writing. On 09/24/2026, at 41,275 miles, the vehicle had no electrical power and would not start. An independent New York State registered repair facility diagnosed the failure as "no power," "not starting," and "bad alternator (burning)," and replaced the alternator assembly the same day. The remedy alternator failed about 5 years after installation. The vehicle averages under 3,000 miles per year. The mileage at installation is in FCA's records and is UNKNOWN to me. Safety risk: the P60 recall states that these alternator diodes can fail rapidly with no output or a short to ground, which can disable ABS, electronic stability control, and the engine and body controllers, and can cause vehicle shutdown while driving and an underhood electrical fire, with limited or no warning to the driver. This failure is consistent with that description: total loss of power and a burning alternator. Had it failed while driving, the vehicle could have shut down in traffic. Warning lamps or symptoms before the failure: UNKNOWN. Availability of the removed alternator for inspection: UNKNOWN. FCA has not inspected the vehicle or the component. It declined to cover the repair, first stating that the recall was completed and no recall is open, then stating that completed recall repairs are covered for only 24 months. It made no finding that this failure differs from the recall condition. In its 14V‑634 report, FCA stated that the remedy alternators used the same diodes as its 180 amp alternator, which it said did not exhibit the condition. In 2017, FCA recalled 180 amp alternators (the federal safety agency 17V‑435) for diode thermal fatigue. I ask the federal safety agency to evaluate whether P60 remedy alternators are failing in service and whether the P60 remedy was adequate.

Subject: 2018 Jeep Grand Cherokee – Sudden Loss of Power, PCM Failure, Electrical Failures, and Concern Regarding Recall-Related Symptoms I am filing this complaint because my 2018 Jeep Grand Cherokee experienced a sudden and unexpected loss of power while I was driving, and I am very concerned about the safety implications and the possible connection to the recall-related electrical problems associated with this vehicle. Before the final failure, my Jeep had been experiencing electrical and starting problems. The alternator failed, the batteries went bad, and I had already paid for multiple diagnostics and repairs. At the time, we did not understand that these problems could potentially be leading to or connected with a PCM failure. I have spent approximately $800 on diagnostics and parts trying to determine and repair the cause of these issues. The most serious incident occurred when I was driving near a school and approaching a stop sign. The Jeep suddenly began losing power and would no longer operate normally. I did not receive an adequate warning that the vehicle was about to completely shut off. The dashboard/screen began flashing, electrical functions began going out, and the vehicle progressively lost power. I was able to slowly move the Jeep toward the right side of the road before it completely shut off. The Jeep then would not start again. This was extremely frightening because the vehicle lost power while I was operating it in an area where there were other vehicles and children nearby. I was concerned about my ability to safely get the vehicle off the roadway and about what could have happened if the Jeep had completely lost power in moving traffic or at a higher speed. The vehicle has since been diagnosed as having a PCM failure. I have already paid for diagnostics rather than simply bringing the vehicle in without any prior information about the problem. Despite this, the Jeep dealershiphas my vehicle now to determine if this is part of recall

The Jeep was giving me a warning sign. It said stop slowly. Your jeep will shut off so I replaced the two batteries. As my Mechanic told me I replaced the alternator. I also replaced the ground wires. Nothing is making my jeep start. We ran the codes on the jeep and it came back as a U0100 code with the PCM system. No connection error. we looked up the recall information and a recall popped up for this 2018 jeep Grand Cherokee. I am being told that I am not affected by this recall.. the jeep was giving warning Saenz before I replaced the battery and alternator. After that. It did not give warning Saenz Anymore. It’s just completely Shut Off With no warning. Leaving me on the side of the road stranded twice. It will not start and it is reading these codes.

Electronic Throttle Control warning light comes on upon starting vehicle while extended crank occurs. When starting car, the push to start feature will not turn over and continuously cranks multiple times. Issue is intermittent- never know when it will happen which makes it difficult to replicate at service center. Took car into 2 mechanics on separate occasions and finally to the Jeep dealership for service. Because issue couldn’t be duplicated- nothing was done. However, recently while driving, same extended crank pattern noise and unstable/rough propulsion occurred while driving on the highway. Same Electronic throttle control warning light came on along with the check engine light. Also cruise control and the auto On Off feature became disabled. I scheduled service with my mechanic as soon as possible and they found the stored code was related to Technical Service Bulletin 2014-004-25 REV.B. This bulletin lists the symptoms I described yet the dealership did not perform the fuel pressure Test and Replace Fuel Pressure Regulator. I called the dealership to schedule warranty service for this TBS and they gave me difficulty acknowledging the TSB was issued for my make/model/year and scheduling a service appt. I spent the last few hours reading all of the complaints on the federal safety agency for 2021 Jeep Grand Cherokee and it is alarming how many of the complaint are for this specific issue. It is dangerous for anyone on the road to be driving in a vehicle you can’t rely on to propel you forward when you press the gas or stall due to faulty fuel pressure regulator amid traffic. An investigation should be done. Furthermore, in reviewing other recalls, I found this is a recurrent issue for Jeep. It appears they’ve been various safety recalls issued for this in the past for vehicles made from 2011-2020. How they haven’t addressed it in new models is appalling. For owners of the vehicle, it’s difficult to have any leverage with dealership since it is not easy to replicate on demand.

The 12-volt auxiliary battery on this 2022 Jeep Grand Cherokee 4xe plug-in hybrid repeatedly discharges to a completely dead state while the vehicle is parked and switched off. The vehicle has failed three times in approximately 30 days. First failure, June 26, 2026: the vehicle would not start. Numerous fault codes were stored across multiple modules, including P0562 (system voltage low). The odometer display was flashing, indicating a module had dropped off the communication bus. Second failure, July 13, 2026: less than 48 hours after returning from a road trip and parking, the same condition recurred. The vehicle required external 12-volt power to start. Third failure, July 26, 2026: a brand-new AGM battery had been installed on July 24, 2026. Within 48 hours of installation the battery measured 5.85 volts — fully discharged. An 80Ah battery discharging in 48 hours indicates a continuous parasitic draw of roughly one amp, which is 20 to 40 times the normal key-off draw for a sleeping vehicle. Owner testing has ruled out both the battery and the charging system. The DC-DC converter was measured delivering 127 amps at 13.9 volts, confirming it functions. The replacement battery accepts and holds a full charge, resting at 13.06 volts after recharge. The previous battery passed a printed conductance and load test. During each failure, the entire camera system and the ParkSense park assist system drop out simultaneously and the odometer flashes. Stored codes include U0159-00 (lost communication with parking assist control module) and B2204-00 (ECU configuration mismatch). Separately, and even when the 12-volt system is healthy, the rear backup camera intermittently fails to activate at startup and sometimes only begins working after 5 to 10 minutes of driving. Safety concerns: 1. Rear visibility. The backup camera intermittently does not display an image when the vehicle is placed in reverse. 2. Loss of motive power. 3. Stranding

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.

The check engine came on as I was driving to work the other morning, and when I got back in the car to head home for the night, my car wouldn't start at all. I have a failed High Pressure Fuel Pump system. I used my own OBD-II code reader, and got back code P0087. This issue is connected to the FCA Z46 recall issued in June 2022. The previous owner/dealership performed the service for this specific recall in May 2024 and was marked as complete. I became the current owner of this Jeep in October 2024, just 5 months after the recall was completed. I have personally driven this vehicle for only 20,000 miles since I took over ownership, which means that the new replacement parts covered under the Z46 recall failed at no more than 25,000 miles. This part is stated to last 100,000+ miles. Not 20-25k miles. However, Mopar states that recall parts are only covered for two years after the recall was completed. This puts the expiration for the 2 year part coverage at May 2026. It is currently June 2026. Just one month out of recall part warranty, and both Mopar and my local FCA approved dealership are refusing to honor the warranty and fix this issue for me for free, covered by the terms of the recall. My Jeep no longer starts at all. I got it towed back to my house so I could have it somewhere safe until I could figure out what to do next about this unexpected break down. Total cost out of pocket would range upward of $10,000 for a full HPFP replacement, including fuel pump module, fuel rails and all high pressure lines, fuel injectors and complete system clean. I'm just one month over the 2 year recall warrenty after recall was completed. And because of that, I'm looking at upwards of $10k for failed parts covered by an FCA safety recall. New parts only lasted 25 months and 20k miles. In no way should I be responsible for the cost of this repair that is obviously now considered a an unremedied recall.
