Uses oil..lots of it. And with it using oil seems sluggish..no passing speed. Burns 1 quart every 2000 miles. Lots of owners are experiencing the same issues with oil consumption and exceleration

In moderate traffic, I was traveling South on germantown pkwy. At a traffic signal, the light changed to red and I stopped the vehicle. After a few moments at a dead stop, I noticed the speedometer jumping from 0 to 10 and then higher.with no indication whatsoever from instrumentation, the engine stalled. There were no indicator signals at all. I was able to restart the engine after placing the shift lever in park and turning the key. I then contacted on star, and reported the incident and asked for a diagnostic. They reported "an ignition problem" and said I should schedule an appt with a dealer.

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.

70,000 miles low oil light comes on, just had my oil changed 1000 mile before. Took in to GM dealer they told me oil pan gasket was bad. Repaired. 1000 miles later low oil light came on, took back to dealership. No issue found. Truck just burning oil! the truck keeps using 2 to 3 quarts of oil dealer will not do anything. Call GM they advise to go to dealership and do oil consumption test. Did this taking it back to dealership every 500 miles to have oil checked. Used 2-1/2 quarts of oil between oil changes. Told dealer this was not normal to fix my truck. Dealer advised GM would not fix my truck because this is normal usage. It is now using about 3 quarts between oil changes. GM told me to go back to dealer to have another oil consumption test done. We see they hide problems well, as was the last recall. How about getting them to address or fix this issue. They are still advertising the afm engine, and raising the normal oil usage from a quart to 2 quarts. As anyone can see with the latest recalls they will hide or not acknowledge the problem. They are worried about their bottom line. Not the customer. See how many changes and service bulletins have been issued due to this oil consumption issue. My GM case # 71-1118075589. They tend to close these case numbers quick. And then they assign you another case number each time you call customer service to hide the fact they have problems. When dealer does oil consumption I find they do not show anything back to GM or attach a record to your VIN #. last couple of time I spoke to GM customer service, they had no record of me ever having an oil consumption problem. And my last case number did not show up in their system. All you have to do to see the problem is "google " GM 5.3 oil consumption problem. You will find more than a few complaints.
