#326 of 337 2008 Tahoe Hybrid A/C problems
Aug 07, 2011 (9:20 pm)
I bought my Tahoe Hybrid in March (2011) and the A/C seemed to work fine... My husband did notice that is seemed to take a little while to cool down. In May we really started to notice the problem because in South Texas it is already starting to hit 100+... sometimes the A/C would work fine and other times it would only blow hot air. So I took it to the dealership we purchased it from and they said there was a small leak and they fixed it... So we thought problem solved... NOT... the very next day the same thing started again.. So I took it back in and they said they couldn't locate a problem with anything... So I took it home and it still would do the same thing. For about a week I would get in my truck at random times to see if there was any specific time of day that it would or wouldn't work. What I found was that it worked fine in the mornings and in the late evening... but starting at about 2pm (when it was 95+ outside) the A/C would only blow hot air.... So I took it back to the dealership where I purchased the vehicle from and they sent it over to a chevy dealership... supposedly the chevy dealership did an upgrade to the computer (whatever that means) in hopes that would fix the problem... NOPE... So I finally called the dealership very aggravated and they told me there was nothing else they could do for me and that I needed to contact a chevy dealership on my own. So I took my truck to another chevy dealership and they said the problem was a pressure switch, so they replaced it... The A/C seemed to work a little better after they did that, but it would still take a while for the A/C to really cool down and even when I have it set to 60 it still doesn't seem that cold... Approx 2 1/2 weeks later the A/C worked fine all day until about 3 pm and then began blowing only hot air... So I drove to the dealership so they could see that I wasn't crazy and in hopes that they would be able to locate the problem while it wasn't working... I received a call from the dealership on saturday saying they were waiting for GM to call them back to see what suggestions they had... and they also told me that in the manual it says that if the sensor in the truck reads 101+ the A/C is automatically set to turn off... I looked in the manual and I don't see anything that sounds anything close to that and I've never heard of that ever... Living in south Texas I can't have a vehicle that isn't going to have A/C when its 101+ outside...
ANY SUGGESTIONS/ or has anyone else had this problem

Sound like a bs line, I am a mechanic and Electronic ee. I can not see how they can design a car like that. In the North East of the state, most AC unit for home is design up to 98 degrees, anything over that. Our ac unit will continue to run unless u have a lot of trees.
I have work for big 500 company before. Dealing with the engineer high up. When I had a problem and they did not have the answer. They would say, call them back when you have it fix.
Means they don't jack.
Techs in dealership are not programmer, they can read error codes and it tells them what the problem is. They are train to read it, but not to change values in the ECM.
I have to say, good luck. I know not to buy from a use car lot. Then again, it is not there problem. Afraid to go to the dealer now. I am smart enough to know a bs line.
"It sound like when you are buying a two story home. You get one story before you buy, then another story after you buy."
Keep us to date please.

#329 of 337 DVD players failure $$$$
Sep 23, 2011 (10:12 am)
We have had a 2008 Yukon Hybrid for just over 4 years and it has been a great car. Other than having to replace 3 door locks, a software reboot smoothing out drivability and having to replace the smallish conventional battery in the engine compartment it has been great. Gets 19-20 both in town and on the highway driving it more like a conventional truck than a hybrid. Still drives great and interior/exterior are holding up well.
BIg bummer this week though. The DVD player recently failed. When you go to Audio on the touch screen DVD doesn't even show up as and option. The local dealership says the only way to fix it as far as they know is to replace the whole DVD/Radio/GPS unit to the tune of about $2000 parts and labor !!!!!! The dealership went out of business this summer and just reopened under new ownership and a lot of the old service personnel are gone so not sure how up to speed they are. The new Service advisor is nice enough but.........
Anyone know if some one out there refurbishes these units. Know on our old Denali the CD player failed and the dealer exchanged the core for a remanufactured unit and the so perhaps that is still and option.
Anyone out there have any insight on this..........

Have your try to disconnect the power. I had a issue on my Chevy truck. Not a hybird. Replug it in and it work. Better off getting a after market radio. Use a I pod.

Just bought a used Tahoe Hybrid with 29K on it - when parked and turned off it sounds like I can hear a tiny little dog barking softly when it sits in the garage. While there ARE dogs in my neighborhood they are not the cause (and my wife hears it too) are we going senile in our 40's? Any thoughts folks.

#333 of 337 Oil Consumption 07' Tahoe 5.3L
Jul 18, 2013 (3:23 pm)
I have a 2007 Tahoe 5.3l flex 78,000 miles that has started using oil.
Have used Castrol 5w-30 Synthetic Blend since buying new in 07'.
Last oil change 1/2013 the low oil light came on way prior to time for change(according to electronic oil life), and I added a quart.
Looked all over /under vehicle found no signs of leak.
It is now time for change 4,000 miles later, and low oil light comes on today, although electronic oil life says 45% oil life remaining.
Checked oil level, and oil level is barely showing on tip of dipstick.
Should I add a quart of oil before driving 16 miles to service center?
Is my Tahoe going to be an oil burner?
Will oil consumption get worse?

Yes, add a quart if it is far where you are going. Know synthetic is expensive. But. If you feel you can make it to your oil change. Then don't. Baby it driving to the shop.
Check if anything is blowing or smoking out of the tail pipe. blue or black smoke usually say, oil. A compression test is needed. Dry and wet test to eliminate the rings. If you have good compression. I would then look at the valve seals. If you have the rubber seal? You can replace them yourself with a small compressor and valve spring compressor and strong small magnetic . Have to remove the valve cover.
I would say it takes 8 hours to replace them. They are cheap in parts. If you u tube it. It will show you how to. Have done many of them.
The rubber dry out and it lets oil down the valve into the cyl and it burns it.

Ive had my tahoe hybrid 08' for about 5 yrs with nothing but issues. From door panels falling off to door locks not working and mainly engine problems. Had to be towed twice when my wife was out of state with the kids for lifter problems, on the same trip. First dealership said it was the oil pan filter and sender, and replaced lifters. After about a month she went to pick up and it broke down again, stranding her in the middle of nowhere. Towed to another dealer and they replaced lifters again. We have had it shut off on us numerous times once on highway, the RPM's will climb up until we put it in neutral, it will lunge forward or stutter so bad it almost dies, and during hot weather which is always(we live in las Vegas) it idles very rough it seems its going to die. Every time we take to dealer they say if its not doing it then they can not check it. Now that its 2 month after warranty and 3k miles passed parts warranty for the lifters, they say they can "recreate" the issue at $130 for diagnostics. And that it might be more if they need to dig deeper at a cost over $1k! Not including amount to fix. For a $54k SUV, its a POS. If they don't fix, i will sell it and never buy GM or GMC every again and will tell everyone I can about all issues. Seems to be a very common problem with Chevy the more i read.
