As of 2015, most of the reviews of Walmart's Auto Service Centers are negative and include complaints of poorly installed components, cheap replacements and slow repairs, notes ConsumerAffairs.com. The negative reviews are relative to many service centers found in the United States.
The most common complaints about Walmart's Auto Service Centers include incorrectly draining the transmission fluid as opposed to the engine oil. This results in the engine oil becoming overfilled and the transmission being run dry, causing extreme wear to the drivetrain. There are also issues with the amount of time it takes to complete oil changes. Many consumers claim that it takes anywhere from one to three hours for the service technicians to change the oil, states ConsumerAffairs.com.
