Buyers should inspect a used Chevrolet Avalanche's body condition, glass, suspension, lights and tires for any signs of wear or failure before purchasing the vehicle. They should also test drive the vehicle on both in-town streets and highways.
Common major problems with used Chevrolet Avalanches include transmission failures, clunking noises from upper intermediate steering shaft, fuel pump failures and excessive oil consumption. Most of these problems occur between 55,000 and 70,000 miles. Common minor problems include the check engine light coming on due to gas cap issues, daytime running lights that are prone to burning out, cracked dashboards, and compact disc player failures due to internal problems in the radios.
Buyers should look under the Chevy Avalanche's hood to check for dirty or rusted parts that may fail. While test driving the vehicle, buyers should park in a clean area and let the vehicle run for at least 30 seconds before moving the car. This allows buyers to check for leaks. Black fluid indicates an oil leak, green fluid indicates an antifreeze leak, and pink fluid indicates a transmission fluid leak. Buyers can take the Chevrolet Avalanche to a mechanic for inspection before purchasing the vehicle. The mechanic can check the vehicle for additional problems and can help the buyer determine a fair price for the vehicle.
