P0E15 fault code: what 16 owners reported

…P0E15 code is active currently. I have attached pictures showing the red turtle and no cel. Service manager says the cel is currently active on the vehicle along with the red turtle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

…The dealer diagnosed P0E15-00 and replaced the electric coolant heater. From 10/13/2025 to 10/17/2025, the check-engine light returned after charging; the dealer repaired a coolant-bypass/air-lock condition in the hybrid cooling system. From 6/30/2026 to 8/7/2026, at 80,222 miles, the vehicle returned for “Service Hybrid System” and EV-charging concerns. FCA 68C PHEV HV Battery Fires recall work was performed, and the electric coolant heater was again diagnosed as failed and replaced. The vehicle was out of service about 38 days. On 9/9/2026, Driver’s Village advised that the high-voltage battery requires complete replacement again. This would be the vehicle’s second complete HV-battery…

The vehicle experienced a concurrent failure of the high-voltage traction battery pack and the High-Voltage Battery Coolant Heater (Diagnostic Trouble Code P0E15). The electric battery coolant heater is a critical component of the high-voltage battery thermal management loop and vehicle cabin heating/defrosting system. When this heater fails, the high-voltage battery cannot regulate cell temperatures in colder ambient conditions, which disables electric propulsion mode, triggers powertrain limp-mode/reduced propulsion warnings, and leaves the vehicle unable to clear or defrost the windshield in freezing temperatures. A sudden loss of propulsion power in traffic or loss of windshield…

…The dealer replaced the main battery and found DTC P0E15-00 (electric coolant heater performance) with the high-voltage coolant heater in a 'locked permanent' unrecoverable state, and replaced the HV heater. The three earlier visits never identified this high-voltage thermal-management failure. Safety risk: a sudden no-start / loss of propulsion, and a failed cooling component in the high-voltage system of a vehicle population already under repeated battery thermal-runaway / fire recalls, where the manufacturer has acknowledged fires in vehicles that had received earlier remedies. The failures were confirmed and documented by the dealer on repair orders. The manufacturer (Stellantis) has…

I took my 2020 Chrysler Pacifica Hybrid (VIN: [XXX]) to Sames Bastrop Chrysler Dodge Jeep Ram in [XXX], to have Safety Recall 52D performed on the high-voltage battery. Prior to bringing the van in, the vehicle was driving and charging completely normally with no charging errors. Sames performed the recall software update to the Battery Pack Control Module (BPCM) under Recall 52D, but their diagnostic scan logged an active high-voltage fault code (DTC P0E15-00 for the battery pack coolant heater) and a stored bypass valve code (DTC P0E7C-00). Despite these active thermal management codes showing up in their system, the technician marked the vehicle as passed and returned it to me. After…

Glendale Dodge (CA) is actively using Federal Fire Risk Recall 68C to fraudulently conceal a separate, critical High-Voltage hardware failure on my 2021 Jeep Wrangler 4xe. Upon intake, my vehicle’s internal VIP diagnostic scan showed an active P0E15 code (Electric Coolant Heater Failure). Per Stellantis Technical Service Bulletins, this code indicates a severe failure requiring a physical hardware replacement to ensure the high-voltage system operates safely. To avoid performing this costly warranty repair, the dealership deliberately falsified the diagnosis on Final Invoice #31349. Under Line C (Customer States Check Engine Light is On), the dealership officially recorded the cause and…

I am reporting a critical manufacturer-imposed restriction that prevents the completion of a life-saving safety campaign, Recall 52D (NHTSA ID: 24V362), which carries a strict "Park Outside and Do Not Charge" advisory.My vehicle has an active fault code P0E15 (Electric Coolant Heater control performance), which is a well-known, widespread factory defect in Chrysler Pacifica Hybrids. When I took the vehicle to an authorized Stellantis/Chrysler dealership to perform the urgent 52D safety flash, the dealer officially refused to perform the recall. They stated that the manufacturer's diagnostic software (wiTECH) completely blocks the 52D software update from being uploaded if the P0E15 fault is…

Electronic Cabin Heater- EV/ Hybrid component that acts as a heating element when driving in electric mode. Common issue since the Chrysler Pacifica eHybrid plug in vehicle was manufactured. Safety: Extreme temperatures we’ve experienced would prevent heat from dispersing in the engine cabin and potential damage to engine/ EV components due to no thermal regulation. Has been reproduced and replaced. Specific to Jeep Wrangler 4xe (2021+): “Electric mode unavailable; Cabin heating/cooling” Check Engine light with DTC codes P0E80-00 and P0E15-00 present on dash. First appeared October 31st, 2025.

I am writing about a mechanical failure on my 2021 Chrysler Pacifica Hybrid. Recently, I took my vehicle in for 2 recalls associated with this model. Recall #: 66B, pertaining to the rearview camera & 52D, which corresponds to the high voltage battery. Recall #: 52D could not be completed at the certified Chrysler dealership due to the failure of the Electric Coolant Heater, throwing diagnostic trouble code, (P0E15-00). Due to my vehicle being past its warranty period, at the time of service, by 9,190 miles, I had to pay $1356.70 for the Electric Coolant Heater to be replaced, before my No-charge Recall #52D could be completed. While my vehicle is technically past its warranty period by…

We recently got the Jeep back from being serviced for a problem (P0E15-00) that seems to be a common issue with a part (hybrid/EV battery pack coolant heater) that breaks every 15-30k miles. Yay! Ours was at just over 17k miles. Now, on top of all of this, I receive a notice for our fourth recall in 2 years, for a battery that could randomly catch fire and there is no fix known yet. The charger for the Jeep is literally right outside my children's bedrooms. If I want to charge my vehicle, I am potentially risking a fire right next to where my kids sleep. If I don't plug in, the whole point of us picking the plug-in hybrid is a total waste of our money. I also have to park next to an…
