Not at 50K and 4 years. I think these parts are 36K 3 years. I think I'll try oem first and try to fix it that way and if all else fails I'll buy that plastic coupler.
I'm betting it is just fatigue in the plastice brought on by it getting brittle in the cold temps.
At any rate I'm still happy with my car. We made it to Detroit for the NAIAS Press days and got some good info (which will be posted at
www.cleanmpg.com - minor plug for my site). Talked to a lot of companies about their plans for alternative powered vehicles. Saw the Volt in person and talked to the director in charge of its development. Lots of good stuff.
I would have probably missed all that if it weren't for the original poster. So again, thanks for starting this thread!
