<Paul> AGREED, AGREED, AGREEDNo There is not a common problem with the roof..................There are many!!
1) Roof glass delamination and spotting uneven of the electro chroomatic glass (corrected with new ecu??)
<Paul> Had mine for over 5 years and 10,500Km. Roof ECU changed way back when first recalled. No delamination, but never drive with top closed (except when caught in rain) so chassis flex does not put torsion on roof.
2) Too may sensors to all agree and be in a happy place.
<Paul> Nothing a battery on off recycle cant fix!
3) Struts weaken over time and in the heat causes roof to flop down and potentially break $ 26K of roof glass.
<Paul> I reach back and privide some support by holding the curved section as the roof folds back. I also had the struts #27 replaced when the trunk with roof open would not hold up with the long trunk struts.
4) Can't bypass mechanism and use roof manually unless you like an alarm sounding continuosly
<Paul> Actually you can. With engine off you can fold the roof back manually as the clutch is disengaged (I do this all the time when cleaning the car). You can also use a hex key to rotate the lugs to hold the roof down (under trunk is a small cap to remove to get to the hex screw). If (and not always), the electronics detect the roof in wrong position when starting engine after manual opening, a battery on-off cycle fixes it.
I was told to stay away before I bought the car for these reasons.
But I did it any way because it's a 575 with a flip glass roof . I would suggest it to anyone who has the patience to deal with the issues.
No regrets. Drive it and enjoy.
