Inspect CV Boots and Joints at Each Service
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.
Check Engine Light Due to Faulty Torque Converter
A problem with the torque converter can cause the Check Engine Light to illuminate.
Various Probelms Caused by Clogged Plenum Tray Drain
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.
Fluid Leak From Transmission Output Shaft Seal
A fluid leak may develop from the propeller shaft seal on the rear of the transmission. Our technicians tell us that replacing the seal will commonly correct this concern.
Engine Oil Leaks
Engine oil leaks are common from the valve cover gaskets and camshaft chain tensioner gasket.
Check Engine Light Due to Vacuum Leaks, Oxygen Sensor, or Catalytic Converter Fault
Vacuum leaks, oxygen sensor failure, and catalytic converter efficiency faults can cause the Check Engine Light to illuminate.
Flasher Relay Failure Can Cause Erratic Turn Signal Operation
Erratic turn signal operation can be a result of a failing turn signal flasher relay which will require replacement.
Inspection of Water Pump and Timing Belt
The water pump may fail resulting in engine overheating and possible timing belt damage. Overheating and/or timing belt failure can result in very expensive engine repairs. As a precaution, it is recommended to inspect the timing belt and water pump at regular intervals.
Multi-Link Suspension Components May Wear Prematurely
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.
Engine Misfire Due to Failed Ignition Coil and/or Spark Plug
An ignition coil or spark plug may fail unexpectedly resulting in an engine misfire and possible illumination of the Check Engine Light.
