The generation one pano roof is another known issue according my service tech. They’ve “cleaned and lubed” mine 3x now and it’s working okay right now but I know it’s only a month or two before it shudders badly and has to be addressed again. The fix is to retrofit the generation two roof but it’s a costly job so they’re trying their best not to do it.Ugh, I meant to take mine in for this.I just passed 50,000 the other day on my July 2016.
I won't be doing the extended warranty simply because if I keep driving the way I am, it's really only lasting me a year and a half to two years at most anyway. I travel a lot. I'm crossing my fingers that the car can keep up.
