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.
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 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.

RepairPal Expert Overview:
The aging of the plastic material in the fuel tank rollover valve, combined with stress from the aluminum ventilation line attached to it, may lead to cracking of the connection nipple. The cracked nipple could leak fuel, increasing the risk of a fire. Dealers will reinforce the nipple on the rollover valve or repair the cracking as necessary.
