Jaguar I Pace Randomly Dies, Critical Power System Alert

Had a similar high-voltage system malfunction on my 2019 Jaguar I Pace. The symptoms matched exactly, sudden power loss, system shutdowns, and electrical fault warnings. The root cause was a faulty inverter issue combined with deteriorated battery cells. When the inverter started failing, it created irregular power delivery, triggering the safety systems to shut down the powertrain. The battery pack also showed signs of premature degradation, which compounded the system malfunction. The repair required: Complete inverter replacement, Battery pack diagnostics and cell balancing, High-voltage system recalibration, Software updates to the power management system This was classified as a serious EV problem requiring specialized diagnostic equipment and expertise. The repair took 4 days at an EV-certified service center since they needed to fully test the high-voltage components. Based on your symptoms, recommend getting a full diagnostic scan from a certified Jaguar EV technician. The error codes should point to whether its primarily an inverter issue or battery-related electrical fault. Given the mileage, these components are still within expected service life, so worth checking if covered under warranty.

Thanks for sharing your experience with the I Pace electrical fault issues. My car showed similar battery warning signs and system shutdowns last month. The voltage sensor readings were also unstable, causing the battery drain problems you mentioned. Did you experience any new issues since the repair? Curious about the total cost of the fix, especially if it wasnt covered by warranty. In my case, I am still waiting for some parts to arrive at the service center and would like to budget accordingly.

Thankfully no new issues since the repair was completed. The high-voltage system error message has not returned, and the car runs perfectly now. The fix was straightforward, they found the battery was heavily discharged and showing signs of electrical faults. The total repair cost came to 290€, which included comprehensive system diagnostics and necessary adjustments to the power management setup. The battery warning indicators have all cleared up and voltage readings remain stable. Looking back, catching the issue early prevented more extensive damage to the electrical wiring and other components. The inverter issue was actually linked to the battery problems, rather than being a separate fault. Make sure your service center completes full testing of the high-voltage system after installing the new parts. This helped confirm everything was functioning correctly in my case. The investment was worth it to resolve the electrical fault permanently.

I finally got my I Pace back from the shop after dealing with those frustrating battery drain and system shutdown issues. The total repair ended up costing 4800€ since they had to replace both the faulty voltage sensor and parts of the high-voltage system. The service center found that multiple electrical faults were triggering the shutdowns. They detected significant system malfunction in the power management unit, which explained the unstable voltage readings I was seeing. The diagnostic process took longer than expected since they had to isolate each component to find all the failing parts. After two weeks of repairs and testing, the car is running perfectly with no warning lights or errors. While expensive, at least I have peace of mind knowing the electrical issues are properly fixed. The investment in a certified EV specialist was worth it to get the problem solved correctly the first time.
