Engine mounts can also wear over time. Oil consumption is generally within acceptable limits but can increase with age/mileage.

Common Transmission Issues:

Occasional reports of rough shifting or hesitations in the automatic transmission, though often resolvable with software updates or fluid changes. Manual transmissions are typically robust.

Common Electrical Issues:

Minor electrical gremlins can occur, such as issues with window regulators or door locks, but major powertrain electrical faults are not widespread.

Suspension Issues:

Front suspension components like ball joints and tie rod ends can wear, leading to steering looseness or noise.
