Ways to Contact the General Motors (GM) Customer Service and Assistance Center

Updated on January 25, 2012

General Motors (GM) is a Big Three auto manufacturer that has produced millions of cars. For such a large corporation, it is not necessarily easy to deal with customer service. GM car owners should learn the best ways to get GM customer assistance.

Like many corporations, you tend to get the runaround if you do not know all the ways of dealing with customer service for General Motors. The company is headquartered in Detroit, Michigan. However, like all car manufacturers, the easiest first step is often to visit a GM dealership for assistance.

Owners of Chevrolet, Buick, GMC, Cadillac, Pontiac, HUMMER, and Saturn vehicles can first visit the dealership where the vehicle was sold if possible. This is not always possible since owners sometimes move a long distance. However, any full-service GM dealership will be equipped to handle customer assistance for most repairs and maintenance and can perform services covered by a warranty. Of course, you may be charged if your warranty has expired.

If you feel there is a problem that GM should fix for free, then that is sometimes possible. For small items like loose windshield wipers that require no parts replacement and only a few minutes to repair, a dealership will actually often do this for free even without a warranty. However, this kind of customer service has its limits with General Motors and all other car manufacturers. This is especially true when you need to replace parts.

The other benefit of going to a dealership first is that there may be GM recalls you are unaware of that need addressing. When a vehicle is recalled, that does not generally mean the whole vehicle is bad. It means there was some design defect that needs to be fixed. These are usually simple items, and GM dealerships repair or replace the recalled part free of charge. You typically receive recall notices in the mail if you are the owner of record of a GM car.

If you feel that you are not treated fairly at the dealership level, headquarters has a GM Customer Assistance Center. The phone number to call depends on the car model. Look at the contact numbers below to determine which GM customer service phone number to call. You can also write to them, and writing is good as follow-up communication if you do not have your problem or complaint resolved when calling the GM Customer Assistance Center.
