Wow...unbelievable some of the things I'm reading here...my, have we become an impatient bunch....
Perhaps it's my interactions with people at Chevy/GM that allow me to say this with confidence...but
THEY DO CARE. Don't fool yourself or others into believing anything but that. You are their source of income. You are the reason they are in business - and now, at long last they realize that to the very core of their operation.
You don't think the reason they brought the Camaro back was because they listened to their enthusiasts? I know that the Camaro team reviews every warranty claim recorded for the Camaro in order to better serve their customers/enthusiasts. I suppose the Oshawa event and plant tour wasn't because they cared about their customers, either.
People like Jeff and his team taking the time to visit, reassure and attempt to rectify situations on sites like this (they are on other GM-enthusiast websites, fyi) is a phenomenal gesture towards their customers and should be applauded....but here I read someone calling them liars? Or worse...politicians?! How disappointing...
Here's a few things to keep in mind. Hopefully they'll hit home, because some folks really need to understand how this business works.
1st, You are only one of several million customers every year. Sorry...:(
2nd, To that end, please note that in last and this year's most recent JDPower surveys: Chevy, Caddy, GMC, and Buick all earned superior marks for service satisfaction. So if you're going to inflate your personal experience to generalize about how awful they are as a company...you'd be wrong, to put it bluntly.
3rd, Though it may surprise some, people can be dishonest. Breaking their vehicles and demanding repairs. People can be wrong...insisting they hear a dysfunctional noise that is actually normal operation...there are procedures and guidelines the company has no doubt authored to protect themselves against these types of people. Sadly, the end result is a process much slower than it would be if everyone were honest and not paranoid.
The last thing I'll say is that yes, I appear to be writing as a GM fanboy. I'm sure it'll rub somebody the wrong way because naturally, all large companies are evil.

So let me at least say that I'm not writing "blindly"....I understand that there are negative experiences out there, I've had my own. You can't be a 100-yr old, multi-billion dollar company and not have some things fall through the cracks. It is regrettable, and hopefully somehow, each and every bad situation gets rectified...
...just please don't post general statements and demonize the company.
