http://www.g8board.com/forums/album.php?albumid=503I have had my g8 for less than 3 months and I must say I am very
dissapointed with this vehicle thus far. I have a liquid red v6 model
and the car looks great with copious amounts of room inside. This vehicle should have been equipped with blu toothand was not, there is a vibration in this car that they can't solve, onstar back up battery has failed, there is a severe lack of torque when launching this vehicle I can't spin my tires. Sunroof motor is noisy as hell, I've had three incidents where I'm flooring the gas and the car would not accellerate, my check engine light came on 30 minutes after my most recent loss of power episode I took it straight to the brampton dealership where they discovered fault code 11 and 21. These codes indicated there there is a problem with both banks of camshafts. I just picked up this G8 after a nightmarish experience with an 07 Saturn aura xr I had to take this vehicle to arbitration and won a buyback. Needless to say gm has struck out. I also just received a letter from gm advising me the G8 has control arm issues.

Unfortunately, while it appears that many of the cars are ok, some turn out to be nightmares and a few people (myself included) have actually gotten rid of them because of it. Sorry to see you're having problems.

Sorry to hear that you appear to have one of the bad apples. While I don't have the V6 model, I will have had my GT for 12 months on Friday, and I have over 23,000 miles on it. Fortunately, I've not had any issues with it (like many others who have had trouble free ownership so far). <knock on wood>

It's unfortunate, but any car maker can come up with their fair share of lemons. When I owned Audis, I also had no trouble with them, but the forums would have owners who talk about the lemons that they got.

Good luck with whatever you decide to do and I hope it works out.

If the wheels/tires are out of balance the vibration will occur at a certain speed, and it usually will decrease if you go faster or slower. If they are out of round the vibration will increase with speed and never get better no matter how fast you go.

An out of balance driveshaft and warped rotors will also cause vibration at highway speeds, and like out of round wheels/tires it doesn't go away no matter what speed you travel.

What did the dealer say about the problem with the camshafts? Do they have a solution for the problem?

Is the "control arm issue" letter the one where they put new seals on the ball joint? GM is trying to fix it before it is a problem if you don't already have clunks.

i just got the letter too saying that the sealing boots on the front suspension lower control arm lower ball joints will not seall correctly in cold temps...i have till november 1st to get it fixed no charge after that i will be charged....thats gay

The camshaft issue is the same as on the Enclave/Acadia/Outlook/Traverse that has to do with the endplay causing advance/retarding issues. Typically at higher elevations. Let me find the bulletin.

i have till november 1st to get it fixed no charge after that i will be charged
As long as you are under 3 yrs/36K miles the bumper to bumper warranty will cover it. I don't see what good this will do anyway. If you bought a 2008 and drove it through last winter the ball joints will be worn out, so it won't do any good to replace the rubber boots. That's probably why I had to have mine replaced on my 2008 during the summer of this year.

oh sweetness!!i didnt know about the 3/36k warranty

It's a large car with a v6 and you expected it to spin the tire's?

Don't have any info yet, I was just told they have to open up my engine
to get to the problem. Service adviser said he has seen this probl in the
Cadillac 3.6 engine. I contacted gm today to let them know how pissed I
am

I have spun mine a couple times. And I have the V6

Yes I do expect to spin the tires. My previous vehicle had the
same engine in a front wheel drive platform and I've got to say that car
went like stink. I could spin those tires at launch at will if I wanted to.

The GT doesn't like to spin them from a stop either. Can you initiate a burnout using the brakes?

J you need a tune & a CAI then you can light them up!

I know. Although getting just some scrub mashing it from a stop makes for pretty consistant launches. lol

My point exactly if the GT barly does it, so then why would you EXPECT a v6 to do it, I am not saying it cant happen but it's not very likely.

Same here. :)

14,000 miles and all is fine.

Has anyone else experienced problems with the TCC?

I took my G8 into the shop this morning because I was experiencing RPM fluctuation's on acceleration and I was told my "TCC" had failed. I'm not really sure what that means, but they have to keep my car for a week to fix it. I have 34,000 miles and this is the 5th time it's been in the shop.

The TCC is a solenoid that locks up the torque converter in your transmission.

Oh ok, I guess that makes sense then. Thanks.

LOL! Well that's meaningless! :slap: Duh!

In a front-driver, the weight transfers off the front wheels, making it far too easy to spin them. This is why serious drag-racing vehicles are all rear-wheel drive.

Can anyone tell me why my key will not come out of the ignition ?? it wont even turn off had to leave it in causing the battery to run dead. any help please thanks john .

Sorry the key stuck in ignition is the 08 g8

You can sometimes fix this problem by turning the steering wheel slightly to "un-lock" the key.

As I expected too. I never could get them to even chirp. JW

I'm pretty sure I've read that if the battery is dead then the key won't come out.

your saturn weighed 3500 lbs...your g8 weights 4000 lbs

v6 G8 don't spin the tires off the line unless the ground is wet

A Saturn Aura weighs less then the G8 does and its FWD not RWD. When you mash the gas on a FWD car the front end lifts and the tires spin where on a RWD car the drive wheels are mashed to the ground harder making them launch harder and NOT spin tires. Thw weight issue should be easy to figure out. As to the rest sorry to hear it man. :(

The weight transfer is an issue to some effect on a FWD car, but there's also more weight over the front wheels because the engine/trans is in front, so that aids in traction. Unfortunately very few FWD cars have a limited slip differential, so power is being applied to only one wheel. This is the main reason our RWD cars get better traction off the line.

If you want to spin the wheels, you have to turn the traction control off.

Does the v6 have a limited-slip rearend ?

No just the V8 does.

I recently had the right head and cam as well as shims in the left cams all replaced under warranty after two months of ownership. The car is noticeably more responsive. As for the traction control, I am well aware of turning it off. I have done it and still can't spin my tires from a full stop. I think this engine might have even more defects. There is no reason that I should not be able to spin my tires at launch.

The V6 doesn't have enough power to spin the tires like the V8 does.

Im not the smart guy but on front wheel vehicles the power from the motor is on top of the wheels ( not a long distance to transfer power) but like i said im new to this and im not the smart guy.I went from a pontiac grand prix gt 2000 and the front wheels spent like hell but when I got my g8 GT there is no spin from take off but the power is there, and last i checked wheel spin looks cool but on the track can hurt you, also remember on the GT they come with Bridgestone Potenza's 050A which is a rubber to road tire with no room for spinning.----(Just my opnion no need for negative comments)

Go for a tire with a harder rubber compound and you'll have lots of fun lighting them up.

I came from a Saturn Aura XR and I find my G8 more responsive (particularly now that it has some miles on it).

Having said that you can't really compare the two cars. The G8 is almost 500 lbs heavier, it's rear-drive, the weight is balanced 50/50 and it's got wider tires (245 vs 225 on the Aura).

...

Only time i've been able to spin the wheels has been while accelerating through a turn from a stop. I've tried everything I can think of to just catch a bit of wheel spin but no luck. I damn near pulled a 180 getting on to the highway from a store parking lot. Stability control stuff popped up on the DIC and the wheels were spinning like there was no tomorrow....fun stuff.

The one time I spun the tires. I turned traction control off and held the brake. I gave it gas and when I heard the wheels spin, I let go of the brake. Next thing I know the back end broke loose and I was going sideways down the street spinning the tires. The road was dry with no precip.

tune - a tune will give you the spins and the chirps all day long.
