Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The check engine light has been illuminated as well as the traction control light is on (indicates ABS needs to be serviced) also transmission slips when moving forward. At times when both the engine light and ABS light are on the engine will reduce power. Transmission was replaced at 63,000 for the same thing! Have had to numerous shops who cannot locate issue. The doors will not lock shut- they come forward and pop out and reopen. Must operate manually.”
NHTSA complaint #10558997, filed 2014-01, 136,000 miles“Cruise control at 46,000 miles works intermittently. Sometimes the cruise works fine, other times it stops working as you are driving. Other times the cruise control will not engage at all. There are no accidents or injuries. Dealer cannot recreate problem, so they will not fix it.”
