Sierra 2500

  • 46,000 miles
Check engine light comes on and engines goes into reduced power mode. Doesn't have enough power to go over 40 mph. While pulling a trailer the engine doesn't have enough power to climb hills or go over 25 mph. I have taken to dealer twice and they say GM is aware of the problem but they don't have a fix for it. It's not safe having a vehicle that breaks down in -15 degree weather and having the dealer tell you that there is no fix for the problem and to just keep driving the vehicle.
