Pontiac G8 reliability - better info

[mkaresh]

I wanted more up-to-date car reliability information that included actual repair rates. So in late 2005 I started getting people together to make this possible. TrueDelta now updates actual repair frequencies, not just dots, four times a year, to track cars closely as they age.

99 G8 owners signed up so far. A great start. The more owners participate, the better the information we can provide on these cars.

To encourage participation, participants receive full access to all results, not just those for the G8, for free.

For the details, and to sign up to help out:

We've updated the results for the Pontiac G8 to include owner experiences through September 30, 2009. With a reported repair rate of 84 successful repair trips per 100 cars per year, the G8 is now worse than average.

The suspension has been a common problem area.

We'll have further updates in February and May. The more owners participate, the better the information we can provide.

Is NOW worse or NO worse?

[RapidG8GXP]

"the G8 is NOW worse than average"

According to his post's last sentence, 1st paragraph.

[mkaresh]

Yes, now worse. That said, if and when the suspension problems are resolved the reported repair rate will probably improve to about average. The analysis always covers the previous year.

[Chewy]

"the G8 is NOW worse than average"

According to his post's last sentence, 1st paragraph.

Yeah I read that and wanted to make sure it was NOW and not NO. People do that all the time around here and that one letter makes as you know a HUGE difference.

Not surprising. I've put all new control arms on my car personally so I didn't have to go to the stealer.

I have also fixed all the squeaks and rattles myself.

[mkaresh]

Just an FYI to participants in the survey: DIY repairs can and should be reported.

[mkaresh]

Updated results next month, including additional stats for the percentage of cars with no repairs and those with 3+ repair trips.

I still like my car....

[foreosu]

I still like my car....

Agreed... Best car I've ever owned. No car is perfect

[mkaresh]

I still like my car....

One problem with a car, which if it's typical is enough to get it a "worse than average" reliability rating these days, is hardly a reason not to like a car.

What few people realize is that with Consumer Reports' survey if even one in four owners reports a problem the car gets the dreaded black dot. And they provide little reliability information in addition to the dots.

I'm trying to get people from thinking that "worse than average" is automatically bad by providing the actual repair frequencies and far more detail than they do.

With the G8 it's, "Okay, the control arms in many of them have had to be replaced." A good reason not to get one? I wouldn't think so.

[DRCUSTOMPARTS]

I have no complaints about my car or the service from my dealer. I had 2 minor issues fixed in 2 visits after owning this car for over a year.

[majesticix]

I question the significance of these tests. People who are satisfied with their products generally don't participate in these questionnaires and I wonder if the results are skewed by "lemon vehicles and/or experiences." I'm not sure if there is any statistical data that would support or refute my claim, but I know from my experience, I usually only speak up if the shit hits the fan or if I had a glowing experience. For most satisfactory experiences, I bet they go unheard. That's just my take.

[DRCUSTOMPARTS]

I agree with you, unless they survey everyone, then the results aren't accurate.

Our survey process is uniquely designed to prevent the distortion you mention. People are only surveyed beginning with the month they sign up. They cannot report old repairs. They cannot know what they'll be reporting at the time they decide to participate.

As for evidence, we do post stats for the percentage of cars with no reported repairs in the past year. In some cases, it's over 90 percent, and many models are over 70 percent:

TrueDelta Nada-odds and Lemon-odds stats (http://www.truedelta.com/latest-lemon-odds.php)

If people joined just to complain, this would never happen.

Just enhanced the related repair history survey so that it can (optionally) be used as a personal car maintenance record.

As always, more participants would be helpful. Updated Car Reliability Survey results in May, with a preview for participants in mid-April.

whats the susp noises i see post about ??? i put 30K miles this first year and live down a sand drive way that gets rutted up a lot and you wouldn't think a car would even make it till you see this blue G8 come through it and i have not had the first thing wrong with my susp or anything ???

[GM_Fan]

I would like to see Grrrr8.net as one of the options on the drop down box for web sites when I fill in my monthly info.

Mine has been Grrrrrrr8. I got almost 14,000 miles on her and no squeaks raddles noting wrong with the suspension super car. My 2004 Colorado never had a squeak or anything and it is still running with 382,000 miles on it and looks almost brand new.

[mkaresh]

382,000 miles? Some people seem to get endless miles out of a vehicle.

Michael is a great guy, his methodology is much better than JD Power or Consumer Reports; he also has a pretty good system for determining "true value" of a car when considering models. His "true value" system is clinical, it doesn't take in the X factor of fun to drive, etc. etc. but it does go into the raw math of what is the better value. Your participation in this, even if you have had nothing but problems or had no problems at all is very important.

Michael, had no idea you were on here. Welcome!

Thanks Mike! Great work on your part! It appears the new car kinks are working through - I see the score has improved a lot from the previous quarter.

[texn884]

With my car just turned 71,173 miles the only thing that has been done to it was the upper and lower control arms and normal oil and filter changes and I am on my second set of Potenzas and two alignments.

Lots of cool stuff from Adams that makes my car shine and look GRRRR8 after each week of running up and down and accross the highways in Texas,Oklahoma and New Mexico.

My scores I would say is 99% to the good it would be 100% if the control arms did not have to be changed.

[mkaresh]

The analysis looks at the past year. It's quite possible that the control arm replacements that bumped the repair frequency earlier have now fallen out of this window, and that no new common problems have popped up.

[texn884]

Seems like they are some real fine cars then. :)

[Seattle09GT]

The early quirks around LCAs and tranny flare is past...overall longer term reliability is proving out.

[TooManyHobbies]

Also the bad Eaton AFM lifters have either already grenaded or been replaced.

[Seattle09GT]

Also the bad Eaton AFM lifters have either already grenaded or been replaced.

True. I'm not surprised that 4/5 year quality is high. Was nervous as I saw these issues - I also forgot gas cap but that is now a recall item (of sorts) so doesn't count in reliability surveys.

[mkaresh]

Were lifter failures common? I certainly remember many reports for the control arms.

We do post all reported repairs to the site, so it's possible to see what's behind he numbers.

[ccs]

Just lost lifter in #4 and destroyed cam. 67k miles.

[1gr8ate]

I havent done any thing to mine that i wasnt going to do other wise and the only issue i ever had was the tapping lifters after i put the 1.85 rr on other then that not one other known issue but i guess i should probably do some of the recall stuff...

[mkaresh]

Just lost lifter in #4 and destroyed cam. 67k miles.

We've updated our reliability stats for the Pontiac G8 to include owner experiences through September 30, 2015. Repair frequencies, in terms of repair trips per 100 cars per year:

2008-2009 G8: 47, low

We have two additional statistics, "Nada-odds" and "Lemon-odds", to indicate the percentage of cars with no repairs in the past year and those that required 3+ trips to the repair shop:

2008-2009 G8: 63, 6

We'll have further updates in February and in May. The more owners participate, the more comprehensive and precise these will be.
