What stands out
No new NHTSA powertrain complaint has been filed on this vehicle in over 6 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Customer reports of 12V battery issues. These range from battery low warning displayed to no-start.

The failure pattern owners describe
The 2019 Jaguar I-Pace has generated widespread complaints across multiple critical powertrain and electrical systems. Battery failures dominate the narrative—traction battery systems fail to charge, lose charge rapidly, and trigger manufacturer fire-hazard warnings that require owners to park vehicles outside and away from structures. Jaguar's interim response limited maximum charge to 80%, cutting vehicle range, and announced a mandatory buyback program, but multiple owners report delays of three to four months with no action after notification.
Parking brake and gear shift mechanisms are failing dangerously. Owners describe parking brakes engaging without input while driving, vehicles refusing to shift into or out of gear, and one driver stranded at an angle in a busy parking lot during an immobilization event. An owner at just 2,195 miles experienced brake failure combined with violent shuddering and inability to shift.
Unintended acceleration occurs without foot input on the pedal, and brakes fail to respond to stop the vehicle. One owner reports three separate incidents; Jaguar diagnostics found nothing and instructed the owner to keep driving the vehicle. A separate owner reports complete wiring harness failure contributing to brake and steering loss while in motion. Electrical system stalling has left vehicles non-responsive even after dealer repair attempts. Owners express deep safety concerns about vehicles continuing operation on public roads.
Failure modes owners describe
Traction Battery and High-Voltage Electrical Failures
Battery system failures including inability to charge, battery warning errors, and thermal overload risk. Multiple narratives cite fire hazard concerns and permanent capping of charge to 80% as interim measure. Owners report vehicles disabled for extended periods with multiple dealer repair attempts that did not resolve the root issue.
When: Variable timing; one owner at 22,000 miles; others months after purchase and through multiple years of ownership
Symptoms owners cite: Traction battery warnings and stop-driving warnings; Vehicle fails to charge or loses charge rapidly after driving a few miles; Battery warning error displayed; Thermal overload risk noted by manufacturer; Coolant warning and service required lights
Codes mentioned: NHTSA Campaign 24V633000 (Electrical System), NHTSA Campaign 24V183000 (Battery replacement)
Repairs/costs cited: Manufacturer issued interim remedy of capping maximum state of charge to 80%, reducing range accordingly. Final remedy: vehicle reacquisition/buyback, with parts for repair stated as not yet available in multiple complaints. One owner reports dealer replaced traction battery and main battery, but failure recurred.
Recalls/TSBs owners mention: Mandatory buyback program announced but not executed in timely manner (3-4 months delay reported across multiple narratives). Interim software updates and charge-limiting attempted but ineffective. Recall parts unavailable. Customers instructed to park vehicles outside and away from structures due to fire risk.
Parking Brake and Gear Shift Mechanism Failures
Parking brake actuator and gear shift control failures that trap vehicles in gear or prevent gear engagement, creating dangerous immobilization in traffic. Multiple owners report engagement of parking brake during driving or inability to shift out of park or into neutral.
When: In-motion failures; one at approximately 2,195 miles after 60 days of ownership
Symptoms owners cite: Parking brake engages while accelerating or in motion; Vehicle refuses to shift to neutral; Vehicle refuses to shift to or out of gear; Gearbox Fault Detected message displayed; Emergency parking brake will not release; Vehicle strands itself at angle in parking lot or unable to proceed
Codes mentioned: Gearbox Fault Detected (message code)
Repairs/costs cited: Parking pawl harness replacement identified and performed by dealer in at least one case. Owner reports concern that actuator could malfunction while vehicle is moving, with unclear safety implications from other known reports.
Unintended Acceleration and Brake Failure
Vehicle accelerates without driver input and brakes fail to respond, creating loss of vehicle control. Reported on three separate occasions by same owner. One separate incident of brake failure combined with steering degradation while in motion.
When: Incidents occurring at 5 MPH or slower in parking, 40 MPH downhill coasting, and at 2,195 miles mileage
Symptoms owners cite: Sudden acceleration as if accelerator depressed to floor with no foot on pedal; Brakes do not respond to prevent acceleration; Brakes failed completely while vehicle in motion; Steering affected during brake failure; Vehicle shudders violently when attempting to stop
Codes mentioned: Electrical Multi-System Failure (per manufacturer wiring harness diagnosis)
Repairs/costs cited: One owner reports entire wiring harness identified as defective by manufacturer. Dealer diagnostic testing yielded no findings after three separate incidents; Jaguar instructed customer to continue driving and asked dealer to test-drive vehicle for 100 miles.
Engine/Power System Stalling and Loss of Power
Vehicle loses power and stops running while driving or during operation. One owner reports vehicle turning off suddenly even while driving. Another reports loss of power while reversing that simulates throttle response failure.
When: April through August and later; one incident after several months of ownership
Symptoms owners cite: Vehicle turns off suddenly while driving; Engine/power loss with foot on accelerator; Loss of response to throttle input (appears as power loss under acceleration)
Repairs/costs cited: One owner reports dealer kept vehicle for almost a month for repair; diagnosis and repair approach unclear. Owner uncertain if repairs were effective.

What owners are reporting 1 most recent
On three separate occasions, two with my wife, and once with me, the car suddenly accelerated as if the accelerator was depressed to the floor even though our feet were no on the accelerator. With my wife driving, she was pulling into parking spaces going 5mph or slower. I was coasting downhill at 40mpg when the car accelerated and the brakes did not respond. We reported each incident to the…

Common questions
How serious is the powertrain problem on the 2019 Jaguar I-PACE?
It's a meaningful issue. 14 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $2,500.
At what mileage does the powertrain typically fail?
Based on the 14 complaints filed, powertrain issues most often appear around 14,550 miles. Some report problems earlier; some make it well past 150,000 with no symptoms. Maintenance habits matter — vehicles that received timely fluid services and were not regularly overworked tend to last longer.
What does it cost to fix?
Independent shops typically charge around $2,500 for powertrain repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to powertrain?
No active recalls currently cover powertrain issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
