Tough stuff. Notably, the EU and UK treat it as a safety issue and have a mandatory safety recall because it affects braking components. Safety recalls don't have anywhere that the manufacturer gets to argue about profit and say "Oh, it only affects a few cars we sold and we don't want it to cut into our profits." 100% of those cars are recalled in the EU and UK, period. Imagine if GM argued that they shouldn't have to replace the defective key cylinders in the old Cobalts because "The profit on those cars was so low..." [that we should continue to let people die instead of doing the recall]
GM pockets like $20,000 for every Escalade, Suburban, and huge Bro-dozer diesel dually 4x4 Truk-Nutz pickup sold. Use some of that profit to pay for the recall of the defective stuff they sold.
Notably, it's weird that ONLY the slave cylinders in the manual transmissions paired to the Diesel engines in model years 2016-2018 are failing. Those are the years of Opel/Vauxhall cars recalled. That whole thing points to a batch of transmissions made specifically for those cars (the transmissions must be made with specific gear ratios and final drive ratios), so whatever company supplied the slave cylinders for those transmissions must have a bad batch for 3 straight model years. Other cars with that transmission don't have this problem, so it must be something specific to THOSE SLAVE CYLINDERS for three years running that is the problem. How about going after the parts supplier for that? The transmission of my car was assembled in Austria, and I assume all the other 6MT transmissions come from that same plant. It's got to be one part supplier giving defective parts. Have them pay for it.
Hey Barry, just to be clear here, you mention from your sources that "Notably, it's weird that ONLY the slave cylinders in the manual transmissions paired to the Diesel engines in model years 2016-2018 are failing"
Are you saying this issue is not happening to regular gasoline vehicles with the 6 speed? I thought your car was regular gas as well and not diesel?
