I have a 2007 duramax with 55,000 miles on it. Just noticed yesterday fuel dripping underneath. Where the line leaves the tank it's all corroded. Probably a $100 line. But what does one expect for $50k. I think this is my last new vehicle.
Last summer I noticed something hanging down under the passenger side. The three 3/8 bolts rusted out at the muffler flange connection.
Also the chrome is blistering and the front and rear emblems have separated.
Did I mention the pitted forged aluminum wheels that I stripped and polished at 40,000 miles because they were out of warranty at 36,000 miles.

PS. I don't think compression fittings are legal to use on brake lines.

Huh? I have never seen a brake line that didn't use compression joints. Is this something new?

Also how many of the rusted lines are on older vehicles? It is recommended to flush brake fluid every 3-5 years especially in humid climates. DOT 4 brake fluid is so hydroscopic it can be 50% water in a couple years and rust the lines from the inside out. I just flushed my wife's 2000 Grand Am for the second time and it must've had 30% water in it and I flush the system on my Firebird every other season.

I was told that a couple times, but I have a buddy who still works at a GMC dealership and hes had it in his truck for 4 years and no issues..
The expansion doesnt seem to affect the ABS..
I will keep an eye on it though..

Trucks are all rusty underneath BEFORE built. I saw rusty rears installed once in 2008 .

I oil them asap when I get a new vehicle
