2019 Jaguar I-Pace electrical system problems

“Update of prior complaints, worsening high voltage battery failure on a vehicle that JLR/NHTSA’s VIN lookup NOW show as having NO Open Recalls. Beginning 9/8/26: The "Traction Battery Fault" warning appears on EVERY start-up, without exception. Since then: The vehicle has displayed “High Voltage System Fault Detected,” "Reduced brake feel", and "Restricted performance" warnings accompanied by PHYSICAL symptoms. On multiple occasions A sudden, hard shudder from the undercarriage happened, as if the vehicle had struck an object. After the most recent "High Voltage" trip/shudder, the max state of charge auto-dropped from 80% to 72%. It had previously been limited from 100% to 80% without my consent. HVAC failure: The A/C has NOT worked properly in ~2 years. In humid/rainy FL conditions the windshield cannot be cleared for hours, and I cannot drive safely until it does. Each fault occurrence has been photographed/dated. Safety concerns Reduced braking feel, traction battery, restricted power, high voltage system faults**, and impaired visibility are safety-critical on any vehicle. On an I-PACE they sit alongside a KNOWN thermal runaway fire risk in the high voltage…”

“NHTSA Vehicle Safety Complaint Update | VIN: [XXX] | 10/7/26 | Owner: [XXX] Over the past three weeks I have experienced continuous traction battery fault warnings on my Jaguar I-Pace. As of approximately one week ago these faults are now accompanied by a "High Voltage System Fault Detected" warning. I had been told by a Jaguar tech that the BECM (Battery Energy Control Module) is supposed to reset and wipe these codes after "4 cycles" of the car turning on and off, so the daily faults have been very concerning. Today the vehicle produced a severe physical shudder and automatically reduced charge capacity from 80% to 72% — a new and concerning development; i'd also like to note that Jaguar's battery warranty explicitly calls a battery defective at 70%. Where some more severe cases were initially reduced to 72% charge by the Jaguar dealerships, my car was set to 80% until today. I have photographed each fault occurrence for documentation. I contacted Jaguar Orlando service to speak with a technician or manager regarding these escalating faults. After a five-minute hold I was informed they have not serviced this vehicle in two years and that someone would call me…”

“Jlr will not complete buyback recall at a fair price. Being cheated due to jlr dragging feet. It has been a year since fires and problem identified. No resolution.”

“The vehicle has experienced the Traction Battery Fault three times, which is the warning signal provided when there is a main battery fault situation. During the latest incident, the warning appeared and shortly afterward the vehicle emitted white smoke with an electrical odor and crackling from the front undercarriage. Emergency services were contacted through 911, and firefighters disconnected the 12V battery to stabilize the vehicle. Two previous traction-battery-related repair attempts were performed by Jaguar, and a third repair is currently underway. The repeated failure of the high-voltage traction battery system represents a potential fire risk and electrical hazard. I am reporting this incident to ensure NHTSA is aware of this high-voltage safety defect.”

“This vehicle is part of a mandatory repurchase. I have had no contact from the manufacturer since March 20, 2025. The vehicle has been modified by the manufacturer from it's origional state while the reacquisition process is completed. It is no longer a usable vehicle because of this modification.”

“The contact owns a 2019 Jaguar I-Pace. The contact received notification of NHTSA Campaign Number: 24V633000 (Electrical System), and the vehicle was taken to the dealer, where the battery energy control module software was updated as an interim repair. Additionally, the contact stated that the vehicle had become undrivable and was towed to the dealer, where it was diagnosed with gear box failure. The contact started negotiations with the manufacturer for the repurchase of the vehicle as a final recall option. The contact and the manufacturer agreed on April 15th, 2025 to the solution. The contact stated that the manufacturer scheduled a meeting for the final repair on May 22, 2025, at 9 AM; however, the manufacturer representative arrived to the meeting two hours late, after the contact had waited for an hour and 30 minutes and had already left for work. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The failure mileage was unknown.
