The passenger side taillight started 'going out' right after the warranty expired-meaning, it would work off and on at various times. Then the drivers side taillight has started doing the same thing. This is a known issue with the gmc taillights and yet gmc has yet to recognize any issue. This is a major safety issue for anyone driving these models with failing taillights. This needs to be investigated
