Transmission slipping, stalling, and difficulty shifting from park are reported. These issues can leave drivers stranded and are expensive to fix.
Engine block leaks, repeated stalling, and electrical system failures are noted. Some owners faced entire engine replacements, indicating major reliability problems.
