No its not normal. This is a fraud. Let me explain. A client of mine (I am an attorney) made a Lemon Law claim, GM ignored/denied her claim, and then we were supplied with an Internal PI (preliminary investigation) report that outlined the oil consumption problem stating the cause was unknown (although thought to be stuck piston rings) and that replacing the rings was no guarantee because, again, the cause is unknown. Meanwhile, GM pretends there is no problem (that it's within there oil comsumption guidlines which were created arbitrarily to combat these complaints), when not only do they know a problem exists. However, its simpler to deny that a valid claim/problem exist because they don't know what the cause is or how or if it can be fixed(thus, a recall would be pointless).
Just got word today, my '07 Yukon XL will have new pistons and rings installed next week. I have been going thru oil consumption tests for the last year and been seeing a problem since 50K miles, I now have 88K on the vehicle. Dealer kept telling me 1 qt. every 1000 miles was normal. Finally two months ago during the oil consumption test (OCT), the check engine light came on. Misfire in the the # 3 cylinder. After inspection, they found excessive oil and a fouled plug(found where all the oil was going, no leaks or smoke). The installed the shield and we started another OCT. Check engine light came on again within 1500K of the shield install. This really worries me. Not sure if I keeping the vehicle or going to cut my losses. I am all for a lemon law claim. My last Yukon went to 200k, i had hope to have the same good service out of this one. If this fixes the issue, great, but I am not so sure.
How do we take advantage of the lemon law?

It hasn't fixed my 2007 suburban. Now we push for a new set of rings & pistons.
