Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Once engine was warmed up, vehicle stalled at stoplights twice and once when starting to move after a stop (when in an intersection). Other times when stopped. Idle speed dropped below 1400, under which it stalls, and it was difficult to rev the engine to prevent stalling since there is no neutral gear, so revving more than slightly can make the vehicle move.”
