I had my truck's ecm reprogrammed last Friday (1/17) due to recall #14v007, and earlier this evening (1/24) the check engine light came in and the dic showed an "engine power is reduced" message. The engine ran very sluggish and I parked it as gm recommended to do in their recall letter. This is the second time this has happened now. I thought that the new software was supposed to correct that issue?.

Intermittent surges, loss of power while in motion, transmission, lack of acceleration. At purchase, the check engine light came on three times before leaving the dealership lot. Dealer advised that the dealer installed remote starter or alarm system was interfering with fault sensor and was not a problem. However the lost power while driving, intermittent surges and stall outs at freeway speed/85 mph still existed. On one occasion consumer was almost in an accident when the transmission clanged between gears and there was poor acceleration. Consumer had to shift into 4 wheel drive or manually downshift, or turn the engine off then on again. Dealer replaced pcm module, fuel pressure regulator and gaskets, fuel pump assembly. However problem still exist. Dealership agreed to hold the vehicle for further investigation. Further investigation revealed that the wires from the dealer installed accessories such as the alarm system and remote starter or anti-thief system, and factory wire from pcm/vcm to the transmission be replaced. Dealer replaced all ignition wiring, wiring from the pcm/vcm to the transmission and replaced the control valve body that regulates the cruise control. Consumer has been without vehicle for more than 21 days and will seek a replacement vehicle if wiring repairs does not remedy the problem(s).
