Consumer Description

DRIVING 65 MPH ON THE HIGHWAY AND ALL OF A SUDDEN MY CAR LOSES POWER. THIS IS VERY DANGEROUS! THE DASH SAYS REDUCED ENGINE POWER. ENGINE LIGHT COMES ON. CODES FOR THE PROBLEM P0120, P0171, P0174, P0300, P2135. I GOT EVERYTHING DONE THAT WAS SUGGESTED THE CODES ARE GONE AND IT'S STILL HAPPENING!! NOT SURE WHAT THE GMC DEALERSHIP IS UP TO BUT THEY DON'T HAVE A CLUE TO WHAT'S CAUSING IT OR HOW TO FIX IT! *TR
