Really close to buying a Denali got a few questions

[popsx3]

Looking at a 2007 Yukon XL Denali, what should i look for problem wise? It has the 6.2 engine, has there been a problem with these burning oil or was that just the 5.3s? i saw a post about known problems but cant find it now. Thanks for everyone's help.
take care-

Vortecs are usually pretty bullet proof, I can speak for the 5.3s because that's all I've ever had apart from my first car. One of the main things is the transmission and transfer case condition, can't see it being a problem for now as it is a newer unit, but a good test is to throw it in tow haul, and any shifting deficiencies are usually amplified when you switch it on, also make sure she's good and warm when you try it , because a cold tranny can hide problems.make sure the transfer case actually works and make sure you dont hear any banging when it shifts the drivetrain around. the usual checks for leaks, steering response and anything else, also a good idea is to get the vehicle reportmfrommthe dealer (if it has been serviced at one dealer they should have every record of what ever has been done to it) Someone else would have to tell you about the burning oil problem, sorry man !

Hope it helps !!

Thanks J. it's got AWD so no shifting in to 4x4. Its at a honda dealer, i asked about dealer records they left a message with the previous owner but haven't heard back yet. I did test drive it yesterday, one thing I noticed is a sleight lag between pressing the gas peddle and acceleration. this being the first GM i have ever driven i have no clue if it is normal. Does this have something to do with the "fly by wire" as the dealer put it?

How many miles does it have? I bought a 2007 Denali in February and I love it. There are some cosmetic issues that are common like cracked dash, loose handles, rear windshield fluid heater, etc. Most of these issues may have already been taken care of by the previous owner like it was for my truck. Also, I never noticed this until recently but it does have a rough idle but I think that's common for this truck. And yes, there is definitely a lag when you press the gas. Get it tuned and your truck will be more responsive and shift smoother. Makes a huge difference. Check out a couple of the vendors here like Black Bear and MJ Engineering. I went with Black Bear and I am very happy with it. If I had to remove the tune and CAI, I'm sure my truck will feel like a completely different truck.

Its got 67k on it and they want 27,990 for
it. I checked for cracked dash, didn't have any in it. Did have water stain on head liner from wire harness gromet in hatch.

It's not the drive by wire that is causing it, it's the GM Torque Management system in the newer GM vehicles. It can be tuned out with a proper tune from Blackbear. It'll handle the lag issue oh are feeling.

Ahh, that makes sense. that is reassuring, i guess my main concern now is oil consumption. Has this been an issue in the 6.2 motors? i have been searching this question for a few days now, with no definitive answer.

Sounds like you have your answer. If you can't find the issue on the web, doesn't sound like it's much of an issue.

I bought mine with 58k miles. It has about 62k now. I took mine in to a dealer for a used car inspection two days after I got it just to make sure everything checked out. I would suggest you do that as well. It's like $120. I haven't had any issues with oil consumption.

 

[gitrduun]

Best thing you can see if they will offer some kind of warranty with it , worth a shot I guess but yeah if the tranny feels solid then I think you have a good unit !!

are there any common issues to expect with this o7 denali. i have an 02 that had tranny issues that seems to be resolved by a new valve body. is this also the same. read about a fuel pump problem for the 07, can this be resolved by replacing with an updated pump or aftermarket

We bought a 2007 Denali (84k) three weeks ago, my wifes, traded her 2002 Tahoe LT in for it.

Love it, it is in great condition, inside and out, drives like a dream, ours has a knock on cold start, but other than that, it is flawless, has 4 stone chips in it which i got seen to, until today. Some ****er put a door dent in it when parked in the parking lot, there car was some distance away, so they must of push the door right open and with some force, my wife and i are pissed. My point is, and from someone who took the plung recently, you could worry all year long if you've bought a solid ride, only to have some nut job go out of their way and ding it. As long as your do your research online (google) issues, costs etc your doing the best you can these days. I would ask if you can take it to the GM dealer (if nearby) and pay for an inspection, mine (85k service) cost me $40, and they reported that it was in good condition. How true that is who knows, but if it was falling apart or something very wrong, at least they would pick up on it.

BTW, now we'll be joining those who park over two spaces on their own in the parking lot from now on... going to look through the forum on advice on getting ride of door dings now ..

I've never had a problem with oil consumption in 20k miles.

After i wrote that trolled this here forums and came into the Paintless Dent Repair (PDR), did a little reading and research on the techniques, so i'm a little happier now. Cheers man.

Sorry for delay, they originally offered her $6500, after 4 hours, they gave us $8900. It was 02 121K Tahoe LT fully loaded good condition. We also got them down from 29.9K asking price to 25.5K before trade in on the Denali.

GM's V8s tend to "sweat" a bit from the oil pan. My 07 Impala SS, 08 Corvette and now my 09 Denali seem to have the problem. Not enough oil to go on the floor but it makes the oil pan look dirty. It is a $1k repair if not in warranty.

My Denali with 45k miles on it never used an extra quart of oil and the oil has usually been full when I took it it to have it changed.

Trim issues can be a problem. Overall ours has been reliable though. I have not noticed any lag with my 6.2 though. Maybe the throttle body/MAF sensor are dirty. If you slam down the accelerator a GM vehicle with an auto will hesitate though. My Corvette does it also, but if you just rotate the throttle it takes off like a rocket.
