Speed sensors in the front wheel of my 2002 GMC 2wd truck have failed every December for the last 4 years the first time I paid to have it fixed the second time it was fixed on a recall the third and forth time it was fixed by my extended warranty company. I called customer service at GMC and talked to a stevie snay on two occasions. First she told me she would do some checking and get back to me. When she called me back she told me that gm would not cover any of my expenses. Then she suggested that I purchase a new warranty. I feel that I have been more than patient with them on this matter and feel that since this is a factory defect on an mvss part that they should cover my costs.
