Gee whiz, another problem GM motor, like the other brands don't  have problems also.

 

I feel for the owners of problem vehicles but the fact remains they all build a bad one now and then.

 

If there were posts from the owners of non problem vehicles this site would be many times it's size.

 

I also believe the way a vehicle is used and maintained is a huge factor that needs to be included in the equation but is hard to track.

 

I guess I'm luckier than the buyers of new vehicles because I've never had any major problems with my used vehicles all my life.

 

 

 

 

Agreed 100%

"What i tend to see in these trucks is the following...

Leaking Condensers

Leaking radiators 

Actuator stuck in 4wd

Oil consumption

Starter motor failure"

For that Actuator, is it bad to leave the truck in auto 4x4 then?  Majority of the time I leave it in auto, but I really only need 2wd until winter comes.

Yeah I’d put it back into 2wd for sure.

thats dumb, why even have an auto mode then haha

Thanks for letting me know, i'll be changing that on my way out of work today.

 

Truck came off the shipping truck with a check engine light on *facepalm* taking it into dealership and having whatever is wrong fixed under NY state lemon law.
Has some minor electrical issues too.  But it looks BEAUTIFUL....discovered it has a 100mph gov though

Search cam phaser failure Ford or Ram.

 

The governments  want fuel efficient engines.

 

This is just how it is.

 

They use high tech solutions this adds parts and increase the potential for issue.

Just took mine in for the second time this year to get half the rods and lifters replaced  Its a '15 high country, and I only have around 30k left on the warranty. I'm thinking it may have to go soon unless I find a reasonable explanation of why this keeps happening and a surefire way to fix it. Any ideas?

Change mine once a year 17 High Country 6.2L use Amsoil SS and filter since new and also dumped all other fluids and over to Amsoil all under warranty.

I had pondered the thought of purchasing a new $60k+ GMC Sierra 6.2, but after talking with some GM mechanics and reading these GM truck forums, I’ve yet to do so. I just keep plugging along in my 1999 5.3 Silverado Z71 with 320K on the odo and no engine/tranny issues whatsoever, and a REAL throttle cable, not this DBW electronic bullshit. Original paint, no rust, just normal wear & tear parts replaced due to age. Luckily, I was able to save $$ by replacing most of the parts myself vs $120 an hour rate. 

 

These modern 6.2 engines are total junk and that includes the 5.3 as well. When I was at a local GMC dealership browsing new trucks, there were 3 fairly new trucks in the garage bays for lifter failure, one of which was catastrophic engine failure. All were covered under warranty, but now you own an unreliable POS. I guess it’s just brand loyalty these days that keeps the buyer coming back, even if it’s junk. More scarier than that was what a salesman told me that day: “It’s HP & displacement that sell a truck.” Oh well, when that day does come, “crate motor, here I come!”

I applaud you to have a 99 with no rust and issues. That same truck in Nova Scotia would be in the bone yard many moons ago although there maybe the exceptions but I haven't seen them. I have a 17 High Country 6.2L bought new and I'm doing everything so it won't rust with yearly undercoating and module since new. So far so good it's like new yet underneath no rust. As far as powertrain Amsoil from front to back since new with a catch can also deleted AFM. Crossing fingers to get many years out of the old girl.

Not everyone wants to drive some brokedick truck.  DBW is vastly superior to cable throttles for traction/stability control and throttle tuning.  

 

I had a 2002 Avalanche North Face Edition for 10 years, same basic setup as your '99.  Plenty of rust issues (especially brake lines and eventually fuel lines).  I replaced it due to not wanting to worry about problems towing on long vacation trips; leaking fuel line and broken exhaust weld on a single trip, replacing a wheel hub assembly in a Wendy's parking lot on a different trip.  Not a confidence builder.  Had it strand me with a dead fuel pump at 85k miles.  I'll take my chances with my new truck.

And a qualified driver will do better than any of the nanny-aids.  I still daily my '84 GMC that doesn't have a spec of rust anywhere, and isn't garaged up here in upstate NY.  It isn't hard to keep a truck from rusting, it just takes a little effort.  It's been NY-FL a few times, and will be going back down in a few years when I build another house.

 

If a new truck is more reliable than an old truck, the issue isn't the truck, it's the maintainer.

i also had the 1999 Silverado, wish i never sold it.  all it needed was trans rebuild and i would of saved $30,000 over my POS K2xx truck.  those where easy to work on and parts are very cheap. enjoy that old beast bud! the new trucks T1 models are bigger Pieces of unreliable shit" dont buy just lease the new garbage.. evrything will be autonimous and electric soon, and the Government will have lock outs on the next models that will further add limitations to our travels, THink Universal ID for your car when driving cross country.

2016 Yukon XL Denali 6.2 liter   65K miles had a bent push rod and rocker arm (just out of powertrain warranty)  Now at 72K miles I collapsed lifters and a dead cam.  Over $4,000 to repair, but GM will cover 25% of that because I am a "loyal" customer (This is my 10th consecutive Suburban/Yukon XL).    Anyone know how to convince the GM cost assistance rep that this is a lousy offer?
