Then within months after the drivers door lock failing both rear door locks quit working within a month of each other. Now none of the doors lock automatically or when the lock button is pushed.

My 2008 GMC Sierra has had the electric door locks fail on three of the four doors. The first occurred after about 36,000 miles and the most recent occurred today at about 64,700 mles. The first repair cost over $300. I have been hesitant to have the other two doors repaired because of cost, but safety is a concern. The two rear doors now will not automatically lock when the vehicle is placed in drive, presenting a hazard especially when tranporting children. I have seen numerous similar complaints on the internet. Shoouldn't GM issue a recall for this problem?

I have a 2008 GMC Sierra 1500. I have read on one post alone about a "reduced engine power" message being displayed, and there are over 400 people complaining about this. The vehicles from GM go into a reduced power and have no throttle at speeds of up to 75+mph. There have been wrecks from this and yet GM does nothing about it. I had the same experience 2 nights ago doing 50 mph with my 3 year old in the back seat. I was a lucky one and had room to pull over before someone smacked into the back of my truck. Please do something for GM owners!!!!!!! this is bs and extremely dangerous! I guess someone has to die first before a recall"?" government motors is crap people. Don't buy!

Power door lock failed on driver door. You can not open door with out lifting hand latch. This is very dangerous-- meaning you can not open door by door handle-- there is no override like provided on other vehicles. Other door failed 2 months later. Truck locks and unlocks doors when moving shifter from park to drive, there is no program option to delete this option. So you lock and unlock doors every time you shift truck transmission to park or in drive. This is not needed in my case, since you can manually do same. This is manufacture defect and should be recalled.

Headlights dim when the brakes are applied, when the truck shifts from 1st to second gear and when the blinkers are used at interstate speeds. Contacted GM and have been told this is normal in all vehicles. Also have had 3 door lock actuators and 1 window motor replaced. Had to have the front steering/rack and pinion replaced. Currently having problem with front door not opening.
