2019 Jaguar I-PaceRecalls, problems, MPG & safety

“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…”

“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.”

“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…”
