Complaint Timeline
Chronological view of owner reports
The way the accelerator pedal sensor is positioned allows for water infiltration from wet carpet / tracked in snow and water. The component is available for inspection upon request. Once sufficiently saturated the sensor fails, and ceases function DURING VEHICLE MOVEMENT. The problem is reproducible but has not been confirmed as a pattern of failure by the dealership. As far as my recollection, the manufacturer hasn’t inspected the part. P2138 is the associated check engine code and the vehicle enters limp mode DURING TRAVEL. The check engine light (and subsequent problems) first appeared while in traffic on 2/10/2026.
