I have 47,000 miles on my yukon slt. i replaced the high pressure fuel pump about two weeks ago for a price of $1,400. now my driver side brake light went out. dealer is telling me nearly $800 to fix. i paid good money for this car and have had nothing but problems.
July 26, 2016 we were in las vegas traveling on the strip and our vehicle loss power and died, it started up after a few minutes. a code was set for fuel pump pressure, then today we were in marna az, and our vehicle died while driving in town. a policeman followed us to find out what was wrong and we told him. to our surprise he has been having the same issue with his 2015 tahoe. he brought his vehicle to dealership and they told him it here was a problem with the fuel pump when the temp is too hot.
