What kind of battery complaint?
Among the 8 battery-related complaints, here's the type mix. These percentages describe what the complaints are about — not how reliable the vehicle is overall.
Loss of power, drive unit, inverter, traction motor, DC-DC converter.
Propulsion battery defects, capacity loss, BMS faults, replacement claims.
Hybrid system warnings, eCVT, motor-generator, hybrid transaxle.
Low-voltage battery deaths, common on EVs and hybrids that use a 12V for accessories.
Battery fires, smoke, thermal runaway. Includes any complaint with fire reported.
Sample complaint excerpts
Electric Propulsion
- [2021] While driving my 2021 Land Rover Discovery (MHEV) in active traffic, the vehicle suddenly displayed an “Electrical system fault – Stop safely” warning. Immediately after the warning, the vehicle lost power and shut down, leaving me stalled in traffic with no ability to safely move the vehicle out of the roadway. There was no prior warning, no gradual degradation, and no driver-caused condition. T
- [2021] MHEV vehicle is offline; car completely shut down, resulting in loss of power on the road.
- [2023] DC DC converter failed while driving. Car shut down and rolled to a stop. Could jump start the car but would only work for 10 seconds or so to move it out of traffic. 1-2 month part delay.
High-Voltage Battery
- [2021] While driving my 2021 Land Rover Discovery (MHEV) in active traffic, the vehicle suddenly displayed an “Electrical system fault – Stop safely” warning. Immediately after the warning, the vehicle lost power and shut down, leaving me stalled in traffic with no ability to safely move the vehicle out of the roadway. There was no prior warning, no gradual degradation, and no driver-caused condition. T
Hybrid Drivetrain

About a half a mile away from service center the car experienced a cascading number faults in quick succession. First it was safety systems, then air suspension, followed by transmission and finally steering, which point the car was able to roll an

Thermal Events
- [2024] My car caught on fire while driving only 5 days, and 210 miles, after being purchased brand new. I first smelled melted plastic, few seconds after that saw smoke rising up under the driver seat and then felt the seat getting hot and saw flames shooting under my seat. All along there were no warning messages or light displayed on the car. The car burned completely and was deemed totaled by my insur
Source: classified from NHTSA complaint and recall data. "Battery-related" includes high-voltage propulsion battery, charging system, hybrid drivetrain, electric propulsion, regenerative braking, 12V auxiliary battery, and thermal-event complaints. Other complaints (suspension, steering, brakes, infotainment) appear in the engine and vehicle-level sections. Rates are absolute counts, not normalized per-VIN — high-volume models naturally produce more raw complaints than low-volume ones. Self-reported death and injury counts are capped per complaint to limit form abuse.
Vehicle-Level Issues
