Known Issues
|
|
Ignition Coils:
|

|
|
Suspension Components:
|
Worn control arm bushings and ball joints can lead to noise and handling issues.
|
|
Climate Control Actuators:
|
Failure of HVAC blend door actuators can result in improper air direction or temperature.
|
|
Window Regulators:
|
Plastic components in power window regulators can break.
|
|
Oil Leaks:
