2004 Chevrolet Avalanche Z66 5.3 from North America
Only good for the 2 years; after that it starts to fall apart
Well where can I start?
First it was the bulbs on the dash board, then it was the "SERVICE ENGINE LIGHT" on, which GM would not fix because I was just slightly over the guarantee of the vehicle, so I have dealt with that beeping sound for all the rest of the miles.
Now 4 months ago the transmission BROKE, and had to be rebuilt.
Back in 2011 I had to replace the OIL CAP because it wore out on the grooves, so they told me.
Now in 05/2014, I am told again that the NEW oil cap that was put in on 2011 is leaking slightly, but they went on ahead and tried something to stop the leak, which DIDN'T WORK, so now I am told I have to replace the entire OIL PAN and parts for $800.00? Are you kidding me!
I really liked this vehicle at the beginning. When I rode in it, it was very comfortable.
But when the problems started to happen and the GM dealer could not fix or replace it at a decent price, I knew I was in trouble. For one thing, before I purchased this truck I had a 1987 GMC Suburban 454 engine big block. The only critical thing I ever had go on that was the timing belt. Replaced it, and it ran like a champ again compared to this 2004 Chevy Avalanche.
I cannot believe that GM does not see that everyone reports the same problems I have had, but they still do not care.
Would you buy another car from this manufacturer? Yes

GM made some cars/truck/SUVs that had some issues in the last decade. The 2004 through 2009 Avalanche had more than its fair share of problems. You do ask the question why couldn't GM get it right after 1 or 2 years... but they couldn't with that model.. it was more of a hit and miss situation with that truck.
2014 Consumer Reports annual auto issue has some years that were more reliable than others. The 2002/2011 and 2013 seem to be better built and have better reliability than the rest of the years. At least according to the people that owned them and completed their survey on them.

Since the "OIL CAP" is not in the oil pan, presumably you meant the drain plug, which is.
What most likely happened is that someone changing the oil wasn't paying attention when they replaced the plug, and cross-threaded it.
Probably too late to make a claim for it now though.

Is the mechanic that told you that you needed a new oil cap for your oil pan the same one that told you that the 454 in your Suburban had a timing belt?
