Mark Levinson Amplifier

[Btrini]

6 months ago I purchased a Certified Pre Owned LX 570 and have been loving it so far.  However, yesterday the sound suddenly cut off while I was driving.  Did some reading and found that these Mark Levinson amplifiers have been acting up since 2001 vehicles.  I took the vehicle to the dealer and confirmed that the issue was the amplifier and enquired as to why haven't Lexus done anything about this issue which seems to be over 16 years old.  I spoke to someone and they suggested there may be ground for a class action lawsuit based on the number of vehicles that have had this issue.  I am curious as to how many have had this problem to see if there is indeed a systematic issue or if they are isolated incidents.

Look forward to hearing back.

Thanks
