My Rear Driver Side Door does the same thing..... I 'unlocked' it with the key fob and then tried to open the door...That's when I started to play with the lock, unlock, button and realized it was not working.
I don't know how long this has been happening but it sucks to think there was a way into my truck without me knowing.
Is there a way collectively we can get GM to notice/acknowledge this?
I went to autozone, or advanced auto to buy oil...... this 0w-20 was like 36 bucks for a 5 quart jug... Of course the v8 needs 8 quarts...
The bill with filter came to like 96 bucks...
Here's my advice - go onto amazon and buy the Oil of choice you need.... I got 2 jugs of Valvoline Advanced Synthetic SAE 0W-20 Full Synthetic Motor Oil - 5 Quart
and the bill was $48.00
