Common Issue 1:
Timing chain tensioner wear (M272 engine), potentially leading to rattling noises and eventual failure. Early detection and replacement is crucial.
Common Issue 2:
Failure of the Electronic Stability Program (ESP) module or wheel speed sensors, leading to warning lights and loss of stability control.
Common Issue 3:
Oil leaks from the valve cover gaskets or oil cooler seals.
Common Issue 4:
Transmission shifting problems or hesitation, often related to mechatronics unit or torque converter issues.
