Just wondering if anyone has experienced any minor/major issues with their G8? The first day I brought mine home it leaked ALOT of gas and I did not find out until the next day when I went to work. I could smell it in the house and when I went into the garage the smell was unbelievable. The dealer told me that the pickup tube seal was improperly installed from the factory. I had to get the third brake light replaced because one of the LEDs was out. Also, next time I am at the dealer I have to get the drivers wiper replaced because it leaves a streak right in my line of sight.

One of my lug nut covers was broken and it fell off. I have to get a replacement...

And everyone's wiper streaks like that. Its particularly bad in drizzle. I'm going to investigate mine tomorrow, when the rain stops, because its annoying.

I haven't had this wiper streaking issue...at least not yet.

My pos batter cable was not tight at all, pulled right off with no force. Only reason I fonud it is because I installed a amp and subs in the trunk..

These are major issues? :huh:

The only major issue I've read about so far is the guy with the broken suspension.

I get weird engine noise between 70 and 80 mph. Kinda sounds like the engine noise you get from a stereo, but its not the stereo, its the engine.

These are major issues? :huh:

The only major issue I've read about so far is the guy with the broken suspension.

I've been watching that broken suspension thread and I don't buy it. Supposedly GM came back and said that the accident wasn't due to a manufacture defect. So what caused it?

I think it was just poor driving skills, or maybe some oil slicks from Spyhunter? My car runs, and drives perfectly. My only problem was there were a couple more pounds in the rear tires than suggested. That was a hard fix :) Other than that, this car is perfect. I can't wait to test the GXP when it finally arrives.

The Stealth GT makes my 20th vehicle and by far the best.

I guess I have been lucky. I've had 0 problems with mine aside from the front bumper being dented from coming off the truck but that bumper is being replaced now as we speak.
Why can't paint be scratch proof? lol

My major problem is that it's white and attracts bugs.:whine:

LOL... I feel your pain!

I have had no problems whatsoever. It's a great car and I'm enjoying the ride.

No major problems here! Unless of course you count the fact that it has rained 9 days out of the last 13 that I have had the car!

mac :gears:

Leaking gasoline (that could be ignited with a pilot light) is not serious?

I've heard the way they bind them down for the ride over on the board causes more than a few issues.

You may know this already (or may not care), but your dealer did that. I saw a couple that came off of the truck and the covers had not been installed.

Well, beside the pollen, I went out this morning to take the trash to the curb, and one of the red tail hawks that live in my yard, decided to take a dump on the hood and left fender.
Now, I don't know if you're familiar with red tails, but when they sh*t, it's huge. There was a spot on my car as big as a pizza! :barf:

Well I got a better story...

Brought the car home, parked in driveway for 2 min, go to get a towel to clean brake dust, hear a loud thump, turn around and a bird **** all over my hood. What stupid animals. And people keep throwing bread outside and letting them eat it. You know where that food is going to end up? Your car.

Anyone have dash glare? I read that some owners were experiencing this problem. I haven't knoticed anything, but I can see under the right conditions it's possible.

Yes. Under the right lighting conditions, the brushed band under the guage cluster will throw a reflection on to the guages. No biggie though.

600 Miles, no issues yet.

That's one I'd like to see pictures of.:nuts:

The pictures are posted in the message, look at post #5 or 6. There are multiple examples. I encourage you to read all of the posts on that thread.

Just got mine yesterday with 10 miles on the clock. Drove home all was well....took my boy for a spin and put another 15 miles on it. When we pulled up to the house, she has a little stumble to it....almost like a miss fire...no DTC pop up so i got my dash hawk and ran a diagnostic test on it and no codes stored....

Anybody experiance this "stumble" i'm wondering if it was due to the tank full of regualer gas the dealer filled her up with....

Everyone needs to check the battery connections. My ground connection was loose which caused my car to lock up. This may also correct any "stumbling" there may be. I knoticed the factory subs getting more juice now also.

Buy a good pair of polarized sunglasses and the glare is gone for any vehicle you drive.

i've only had my black g8 gt since tuesday (may 20th)...but have noticed one oddity. when i'm cruising at 70mph or faster, i get a constant, high-pitched noise. at first i thought it was the tires or wind noise, but it must be coming from the powertrain (or something attached to the motor) as the sound vanishes immediately after i take my foot off the gas. if i manually downshift the car to 5th gear, it also goes away even when the gas is applied.

so, anybody wanna venture a guess? the only thing i can come up with is that it's either gear whine from the 6th ratio in the tranny, or some accessory attached to the engine is making this noise. i'm dumbfounded...anybody else notice a high pitched noise while cruising at interstate speeds?? thanks for any help you can provide!

That high pitched noise sounds like it's comming out of the stereo speakers to me. But yes I hear it too. It seems to be happining at all speeds with my car with just a little bit of pressure on the gas. When I take my foot off, it stops. If I punch it, it stops.

Now, since i've tightened up my battery cable, I haven't noticed it, but then again, I haven't been light on the gas either :).

Anyone else hear this high pitched noise? I'll check again after work. (check your battery connections!)

My stereo is usually blasting between 20-25, so I cant hear anything. Phone ringing, radar detector, horns beeping, people screamin to get out of my way, nothing.

this radio is loud as hell. at level 20 its pretty loud for me. And the bar is only at like 1/4 the way. i wonder what maxing it out would do. prob bleed from the ears and cause severe damage. Bass sounds like ass in this car though. rock music = good. rap = horrible. I even played wit the thing in the trunk. It just doesnt bump like bass should, more like it vibrates and doesnt thump.

I don't think the stereo sounds bad at all. It's not gonna thump like an aftermarket system with dedicated subs, and enough amp to light up a small town, but it's decent. I think the center dash top speaker really makes a huge difference in the sound imaging, especially if you have a cd that was mixed with a really good sound stage.
The one thing I don't like is that newer cds have such a pumped up bass line when they are mixed. So, if you have a mix of old an new cds in the deck, when you switch disks, you have to dump the loudness on the newer ones and turn it back on for the older one. BTW, the fidelity of the older (circa late 80s, early 90s, sound much better than new issue ones).
I have had my stereo up to 40 on the volume scale. that was with an iPod plugged into the AUX. I had the volume on the iPod turned down though.
But, generally, I live life between 15-25, volume wise.

i sorta wondered that myself. the "noise" is still there whether i have the stereo on or not. but i don't suppose it really matters since i could still be getting feedback through the speakers even with the stereo off. i'll have to check my battery connections.

per the blaupunkt system, imo, it's just OKAY. i wish it had more distinct bass instead of the muddy tones it gives off. but it'll suffice ... when i'm flogging it i'd rather listen to the engine anyway ... :)

I don't have the problem anymore that I can tell. and I'm very picky. I bet your ground cable is loose :)

BTW, the noise would happen when the stereo was on or off in my car.

hummm...just checked and the cable running from the battery to the car chassis is tight on both ends. guess the mystery continues... :(

Wow, sorry to hear that man. I hate those extra noises....just turn up the stereo :):driving:

i just hope it's not a bearing in the tranny or rear diff!!! oh well, i guess if it is, it will only get louder with time...and then will be easily tracked down. :(

I don't seem to have any whining in my car, other than if I take a few of the people I work with for a ride. :)

took my g8gt in for recalls today and asked them to check battery cables !!!!.Guess what loose !!!So thanks a bunch for info!!!!

what recalls?????

Well they are major issues for non-GM owners... GM owners are just used to sub-par build quality :)

The gas leak IS a major issue but the rest are minor issues.

what recalls?????

there are no re-calls out on this car, he meant TSB's...

Anyone have a list of TSBs? My search button is busted. ;)

Very, very true. Wikipedia link: http://en.wikipedia.org/wiki/Loudness_war
Basically, they're making music sound 5h1ttY so it can be louder.

When I got mine it pulled to the left and they told me to put 500 miles before they would fix it :bs: but they did fix it drives fine now. The other problem I had is the floor mats don't fit right the don't lay flat they tried 2 other mats and they were worse.

there are no re-calls out on this car, he meant TSB's...
There are 2 recalls out on these cars #08150 reprogram ECM and #08090 recalibrate the SDM depending on when you car was built if you have one of the first 888 you will most likely have this anything after 4/28/08 might not or might have been done before you picked it up. The ECM reprogram does help the shifting and jerky throttle off idle.

^those are TSB's not recalls... recalls are a defect, and you would get a letter in the mail about it... TSB's only affect some cars, as you said...

They are recalls when they run a vis on the car they come up as recalls the letters take time to come out and it says recalls on the invoice and know what they are I have 12+ years as a GM certified Tech so I think I know how to read a vis a TSB will not come up on a vis.

my dealership has said nothing, and my friend, who has been a GM Master Tech for 25 years, said there were no recalls out on my g8, and i got it april 24th??? i'll check tomm, but everyone else has referred to them as TSB's, as i dont think they effect the majority of g8's...

if you get a list of tsbs, would you post them? the ntsb site doesn't have any as of last check...thanks!

When I got mine it pulled to the left and they told me to put 500 miles before they would fix it

Your smilie indicates that you are unaware that GM's long standing policy (since 1997) is not to check the alignment or align vehicles with less than 500 miles.


• 0 - 800 km (0 - 500 mi): Due to the tie down during shipping, the vehicle's suspension requires some time to reach normal operating position. For this reason, new vehicles are NOT to be aligned until they have accumulated at least 800 km (500 mi).

As pointed out in the other thread you posted in, GM Vehicle Inquiry System (VIS) does not show 08090 & 08150 as "Recalls".

In the "Required Field Actions" section, they are listed properly as "Service Updates".

A final point, a "Service Bulletin" can show up, as it does for your car, in the "Service Informational Items" section, if there is an appropriate one.

Funny, my invoice does not have the word recall anywhere on it. I had to goAnd yes, my car was delivered before 4/28 and yes, I have had both of the Service Updates done.

Reading right off of the invoice:

If they were recalls it wouldn't be "Per customer request" now would it? We need to put this FUD to rest. There are no "recalls" on these vehicles...YET.:rolleyes:

what is the reprogramming of the ECM & PCM supposed to accomplish per that service campaign? just wondering as i'd like a smoother idle from that v8! :)

I don't call them what I want, I call them what they are, what GM calls them, "Service Update Bulletins".

I also never said they were "TSBs", as they are not, they are "Service Update Bulletins".

Cylinhder deactivation can cause that on these vehicles as well as Mopars with it. It can also cause a light judder through the floorboard, seat and wheel of the car while cruising.

First time driving in the rain, and the wipers suck. Leaves a smear right across the drivers view. Very helpful GM :damnyou::slap:

But yeah, I wish they would've had the passenger side wiper stop before it came into the driver's field of vision.:(

Car's been tight as a bank vault. Over 1000 mi

I'm getting quite a few problems with mine:

Extremely rough idle that tapers off after stating up after not running the car for at least five hours or so. After starting in the morning, when I'm just about to come to a complete stop (moving about 1-2mph with the brake mostly depressed) the car will randomly feel like it is trying to lurch forward and then lets go.

At quite a few different speeds mostly in the 45-65mph range, when keeping a constant speed, the car will get a low vibration through the pedal and seats and an annoying low droning noise can be heard.

When accelerating past 50mph and then letting go of the gas I will hear a light thud in the drive train. This has even happened when exiting the highway and just coasting down below 50.


These are just a few of the more major ones I am noticing. Not to mention the bump in the floor mats between the attachment points and the light being out on one of the heated seat buttons. Just over 1500 miles and going in for service shortly.

First off, it's an American V8. It's going to move around a bit. and have your brakes checked.

Second, the vibration is called AFM (saves you gas)

Third, I'd have the thud checked out. Might be back fire?

I only see one potential minor problem, nothing major.


I'm taking mine in because it's not fast enough :) the shifts that is.

:iagree:

As for the thump at 50 mph, might also be the tranny shifting up or down.

There are no "recalls" on these vehicles...YET.:rolleyes:

According to my dealer when I had 9 ECM updates done, there is a recall pending for these cars. He didn't have any information on what it was for, but said there was one pending and he would call me as soon as he had more information on it.

2400 miles and all is great with the GT.

It is a great ride and most of us on this board appreciate it's quirks.

That rough ride someone complained about is how a 4100lb car with 2 passagers and golf clubs in the trunk gets 16mpg... It's running on 4 cyl.. WOW technology is great.

The rough idle that was complained about! Are you crazy.. This car is a 6L with massive cylinders. NOT a turbo, twin over head cams...Real & pure displacment, WTF did U expect.

Im having fun with mine and hope everyone on this board appreciates this car for what it is..If you don't order the KIA with a V8!

i definitely can feel the vibration and hear the drone with the engine is in 4 banger mode. 3 liters is pretty big for a 4 cylinder so i don't let the noise/vibration bug me. at least afm doesn't seem to cause any jerkiness and it's helping with gas mileage!

i have also noticed the lumpy idle. on my car it comes and goes. sometimes glass smooth, other times the whole car shakes...:( leaving it in drive alleviates the issue somewhat...

i also have a very high pitched noise when driving at speeds over 70 mph that goes away when i let up on the gas. so far nobody else has reported that.

anway, despite these annoyances, i'm still really enjoying my black mad max machine!

Check the post I quoted. I was talking about the broken suspension link. There are no pictures in that thread.

Sorry, recalls are mandatory something needs to be done immediately. These ECM/TCM procedures are not. They are ONLY supposed to be checked when or if a customer brings their car in for some other unrealated procedure - such as an oil change. Or if customer complains of an issue that the "Service Update Bulletin" identifies. It may or may not even be required by GM to be done except when the customer complains. There are no letters going out of these reflashes. If it is a recall it will eventually post on NHTSA. And a recall will usually generate a TSB. Also only posted recall for ANY 2008 Pontiac (at NHTSA)is for seat studs on a small number of Solstice.

i definitely can feel the vibration and hear the drone with the engine is in 4 banger mode. 3 liters is pretty big for a 4 cylinder so i don't let the noise/vibration bug me. at least afm doesn't seem to cause any jerkiness and it's helping with gas mileage!

i have also noticed the lumpy idle. on my car it comes and goes. sometimes glass smooth, other times the whole car shakes...:( leaving it in drive alleviates the issue somewhat...

i also have a very high pitched noise when driving at speeds over 70 mph that goes away when i let up on the gas. so far nobody else has reported that.

anway, despite these annoyances, i'm still really enjoying my black mad max machine!


+1. After driving with no other noise (HVAC and stereo) I can still hear that high pitched noise from the front. It's on my list to discuss with the service department at my 3k oil change along with the wiper blade smear, the popping noise from the front suspension and the long shift/hesitation I'm experiencing.

hey, when you do head into the dealership...let us know what you come up with on the "high pitched noise" and your other issues! i have yet to hear any popping coming from the suspension, but i occasionally do get what i'd call a drawn out shift that ends with a thump. i must say i'm not too impressed with the 6l80e. i think it could use some fine-tuning ... :( :)

First off, it's an American V8. It's going to move around a bit. and have your brakes checked.

Second, the vibration is called AFM (saves you gas)

Third, I'd have the thud checked out. Might be back fire?

I only see one potential minor problem, nothing major.


I'm taking mine in because it's not fast enough :) the shifts that is.

This makes me feel a bit better about it, although I'm still taking it in for a few other minor issues.

The problem with the vibration is that it is only a certain speeds/rpm ranges. It doesn't occur every time AFM kicks in (I've checked it with Engineer Mode) and it lasts until you accelerate or decelerate. I've set cruise before just when it occurs to see how long it would last and it will do it indefinitely. It just doesn't seem like this would be AFM.

Sounds just like AFM to me. AFM turns off if you touch the gas and should stay on with cruise control unless you come to a steep hill that requires more power to maintain speed.

I have what I think might be a new issue. I went in for a oil change, TCM/ECM re-flash, and a random "pull" in the steering. Based on earlier posts, I suspected I might have a combination of "tire" pull, tire balance problem, or alignment issue.

The dealer found the tires slightly out of balance and the alignment close to spec. After adjustments, the mechanic drove the car and found the same "pull," which occurs at all speeds (it almost acts like a sticking front caliper).

Luckily, I have a smart dealer and mechanic, because they gave me the car back while they "check with GM" on the issue. The mechanic suspects a steering rack issue or hydraulic pressure imbalance in the steering system. Of course, they haven't seen this system yet so they are only guessing!

I'll send an update when this gets sorted out, but am wondering if anyone has had the same issue?

The only problem I have is the milage.....numbers keeps getting higher and higher! Mkae it stop!

I also have this problem...

when i step on the pedal, i get thrown back in my seat. is that normal?

also, whenever I drive around, everyone seems to stare at my car. is that normal or should i trade it in for a civic to blend in?

LOL!
Every time I drive it my cheeks hurt....I can't seem get the ***** eating grin off my face!

Lmao!!

My G8 GT is at dealership now waiting for new TCM. 1000 miles and already in the shop waiting for parts.:(

I cant put gas in mine...everytime I slide the nozzle in and squeeze the handle it clicks off like it already full. Had it at the dealer today and they found nothing. Took it straight to another gas station and same thing happened again. That is three stations, all different pumps, acting the same way. This is not a good problem for a thirsty V8 to have. Anyone else?

Nope. I know my Silverado was tricky to refuel. You couldn't jam the nozzle all the way in or it would do like you describe. I assume you've tried putting the nozzle in in varying amounts to see if it'll stay on. With my Silverado you couldn't put it more than half the way in.
