Battery drain is a common complaint, leaving owners stranded. The electrical system can also trigger various warning lights and malfunctions, sometimes within hours of ownership.
Fuel injector failures and fuel pump impeller issues have been reported, which can affect engine performance and may lead to stalling. Some owners mention open recalls for these issues, though none are listed for this model.
