Known Problems
Oil leaks from the camshaft drive pulleys and variable valve timing hydraulics are common. If the variable valve timing hydraulics is leaking, the Check Engine Light may illuminate from inaccurate valve timing.

A problem with the torque converter can cause the Check Engine Light to illuminate.

Fuel quality must be maintained to avoid engine misfire problems; the misfires may cause the Check Engine Light to illuminate.

Premature wear in various multi-link suspension components can cause noises that are difficult to diagnose. Worn suspension parts can also cause uneven tire wear and create steering alignment problems.

The anti-lock brake system (ABS) control module may fail causing the ABS light to illuminate. Failed modules should be replaced to restore ABS operation.

Erratic turn signal operation can be a result of a failing turn signal flasher relay which will require replacement.

Our technicians recommend having the constant velocity (CV) boots and CV joints inspected at each service. Servicing torn CV boots early can prevent the need to replace the CV half shaft or CV joint.

Clogged sunroof drains can allow water to enter the interior and accumulate under the carpet where various control modules are mounted. Over time, the accumulated moisture can damage the control modules.

Clogged drains can allow rainwater to accumulate in the plenum tray (at the base of the windshield). The water may leak into the vehicle's interior, brake booster, or electrical components, which can lead to major problems. Our technicians recommend keeping the tray clear of leaves, pine needles, and other debris.

The digital display portion of the instrument cluster may fail. Our technicians tell us the entire instrument cluster will need to be replaced to correct this concern.
