Owner report 11469104 · 2022-06-14 (June 14, 2022)

While my wife and I were driving on the interstate, all dashboard warning lights came on at once, and the car began rumbling at regular intervals as it tried and failed to switch from electric vehicle (EV) mode to hybrid EV (HEV) mode, and the engine wouldn't start.

Each time the engine tried and failed to start, the car started accelerating again. I pulled off at a gas …

Emerging complaint spikes

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.
