Driving on Interstate at a speed of 70 when truck lost power. Check engine light came on and other lights on dash came on also. 2007 with 160k miles original barely driven. This year should be a part of the Class Action Suit

Driving on Interstate at a speed of 65, truck lost power. Check engine light and all lights on dash appeared I initially mistakenly reported the wrong mileage of 160k. My vehicle only has 135k miles on it

The truck in question has LESS than 163k miles and burn a quart of oil a day, loss of power. There HAS been a recall on this SAME MOTOR 5.3 but while this year was ACKNOWLEDGED it was NOT a part of a recall EXCEPT for passenger side air bag that was replaced at dealership and damaged dash in process. Not it is NON DRIVE ABLE due to oil pressure issues

My truck was diagnosed with bad rocker arms causing my truck to lose power and eventually breakdown.

There seems to be a relay problem in the fuse box under the hood. The first problem happened about 3 months ago. The truck was parked. It had no power. It would not turn over and had no instrument panel. Checked fuse bank and swapped relays around for the start relay. After swapping around a couple of times, it cranked. It ran ok for three months. Next problem occurred with my wife driving. With no warning it lost power and died. It would not turn over. After trial and error, I swapped around relays for the crank & run relay. It started. Note, I did not replace any relays. I just swapped the out with other relays. When swapping relays, the other functions worked as well. This second time was very dangerous as my wife was driving down the road and it just died. I have no idea what to do about it with it working fine for the moment.

Will happen intermittently, as described by other gmc owners. See similar issue with other owners at this address: http://www.gm-trucks.com/forums/topic/129454-my-fix-on-my-silverado-electrical-problem/?hl=stalling see also: the federal safety agency reference #10036550 tsb reference #pit-4730a vehicle is unmodified. The issue is with the battery cables and attachment to the frame and fuse panels. Affects a wide variety of gm and chevy models, and should definitely have a recall, as this causes a very dangerous situation. What happens is : 1. Truck will be running fine, as it should. Intermittently, without warning will start having door locks go up and down, along with check engine lights, gauge cluster resetting and complete power loss to the engine and components (power steering, brakes, etc.) 2. Upon shutting off engine experiencing full power loss. Cannot crank engine until power has been restored by popping hood and wiggling battery terminal cables. The reason why this is dangerous and should have an immediate recall, is first, when this happened I was traveling at 80mph. The vehicle completely shut off, causing me to have to guide to the side of the road without the ability to use blinker, power steering, or power brakes. I have communication with other gm owners of the same year range, but affecting multiple gm and chevy models. (one is 2009 yukon, describing the same issues.) I know that this complaint has been issued by other people as well. It is time for action.

I had a 2007 gmc sierra. Throughout the life of this vehicle I've ask why the 5.3l motor burns a quart of oil or more during oil changes. Constantly ask multiple dealers to inspect and they continued to state that's just this engine and would never mark paperwork to check. Always stated it will burn a little oil in between oil changes. I continued to believe this as other owners of this vehicle type told me same information. On or around feb 7, 2014 engine dropped cylinders and lost most power to vehicle while on interstate. I'm concerned as it lost power and dramatically slowed but also that I've had a faulty product since buying and no recall was issued. I maintenanced this vehicle properly. After telling me the cost to replace the 2 cylinders or engine I had a decision to make. This engine should be recalled as it has major problems. Unfortunately gm didn't recall the engine and fix it properly within my warranty timeframe. I even bought extended warranty. Now I've had to buy new truck which I wouldn't have bought if engine was still running in 2007 gmc truck. These "eco" engines need to be reviewed.
