2010 Cadillac CTS-V Problems
Extended life coolant may become contaminated and require cooling system service before the recommended 100,000 miles.
Brake fluid can become dirty and may cause problems with the hydraulic system parts in the brake system. We recommend flushing the fluid at least every 60,000 miles.
One or both secondary air injection check valves may become restricted causing poor air flow resulting in illumination of the Check Engine Light. It is often recommend to replace both check valves even if a fault code is set for only one bank of cylinders. Replacing only one valve may result in a return trip to the repair shop.
The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time
