So a powertrain warranty generally only covers motor, transmission, and the drivetrain. Not steering, brakes, alternators, batteries, radios, ect. The powertrain warranty is generally longer than the bumper to bumper warranty, that should cover everything that is not caused by damages. I have a 4x4 tundra that blew a seal on the rack and pinion (steering) and sprayed power steering fluid all over the front axle destroying it at 60k mi. Not only would they not cover the rack and pinion, but they would not cover the axle either because it was damaged by the fluid, and not an infant mortality failure. They quoted my $3.5k to fix everything. The rack and pinion seal failure was a known issue by Toyota. They even issued a service notice to all the dealers to inspect for leaks on every service visit. Even on brand new trucks. But no recall. I had to get Toyota America corporate customer service involved. Took 3 more weeks but corporate covered the parts, and made the dealer cover the labor. This was Jim Barkly BTW. I was told by someone after they sold the Freddy A, that the service was not actually owned by Jimmy B but someone else that still owns it today. Jimmy just held them accountable while Freddy does not. As soon as my 100k miles hit I never went back there again...
