Customer Complaint

The vehicle intermittently goes into limp mode, loses power, displays multiple warnings on the dash including “Check ESC,” “Check Injection System,” and “Check Auto Gearbox,” and occasionally shuts down. After this occurs, the engine becomes difficult to start, requiring extended cranking.

Problem Summary

The vehicle experiences random and repeatable loss-of-power events that trigger multiple system warnings. When the fault occurs, the transmission holds gears until approximately 4000 rpm, consistent with protective limp-home strategy. After each episode, the engine cranks for an extended period before starting. The issue is intermittent and may not reappear immediately after clearing codes, but returns once the fault recurs.
