Internet forums aren't the best place to determine 'widespread problems'.
On a statistical level no one would disagree with your statement. The sample size and methodology is small and non-existent, respectively.
Logically this is
exactly what internet forums are for: to reach people everywhere. Whether we're talking about how much we love this car, how to change out lights, how best to use certain things, speculation about future features, or yes to discuss problems, internet forums almost couldn't be better as a way to determine widespread problems.
Like in this case we have several users in this thread who report they have a Genesis with no thumping whatsoever, even with cold temperatures and low tire pressure. For my vehicle I'd have Flintstone-esque tires at 17 F and 29psi. At 40F and 36psi cold, the problem is harder to detect. I've now read those threads again that I mentioned in my last post, and we have the OP of those threads who says he/she sampled other vehicles on that dealer's lot and they all had the problem. So that could be a bad batch. But elsewhere in those threads there's another person who sampled three cars on a dealer's lot in an entirely different part of the country and they all had the problem. Bernster just reported his/her dealer tried swapping with FIVE other vehicles and they all had the problem. I'm not even counting the people who have reported issues with just their cars.
It would seem logical to use this forum to try to figure out if there's any rhyme or reason to the problems. VINs can provide clues. The last six are reserved for the manufacturer and are usually production or serial numbers. The one before that (11th from the other direction) is for the plant. My last seven digits are U040961.
There are four in this thread who have reported no problems. Ernie3647 and rickfen have not experienced it despite low pressures and temperatures, and BRJACKET has not experienced in warm temps, and dubbyak has not experienced in an unknown situation. If those users, plus those in the other two threads about tires could post the last seven digits of their VINs that would be critical to tracking these problems down.
Might be even more important to post tire manufacturer dates too. Look for the DOT code on the tire. Mine is DOT T7EF 1A H 2614. Just post the last four, in this case 2614 means the 26th week of 2014, or basically the last week of June.
In terms of numbers of vehicles (not necessarily users) there are far fewer who are reporting (so far) no initial flat spotting, so it's extremely important those users post theirs! Thank you.
