Before I bought the IS-F, I cross shopped a couple other cars, C63, M3, G37, Cayman, GT-R (would like to but not a serious consideration due to price difference) and believe it or not, Mitsu EVO MR.
Out of curiosity I still follow how these other cars are doing on various blogs and to my surprise I found that the new double clutch trannies seem to be failing left, right and center. More than coincidence (although some owners stubbornly refuse to admit) but owners have reported failures within 5,000 miles of driving. The C63 and G37 don’t have the same problem because they don’t use the double clutch trannies but I read about failures in VW DSG/PDK, BMW M-DCT, TC-SST on the EVO and G36 in the GT-R. These range from hydraulic pump failure, overheating, stripped gear and various solenoid breakdowns. The result is usually a tranny replacement and weeks out of commission because most of the time the entire tranny has to be shipped to Germany and examined by Getrag. This could be $$$ when the cars are out of warranty.
A number of people are starting to think that the double wet clutch systems are unproven and not ready for use on production casrs. Hopefully our 8 speed trannies are more reliable.
