the quest we have is an 04 SE with a little over 138k. I agree the transmission is problematic but I think the tranny (at least in the se) is outsourced, not made by nissan. That tranny is used in other brands like volvo and gm. thankfully the one we got has probably been rebuilt and is doing fine for now. I say probably b/c the cooler hoses are clamped with worm clamps, which nissan doesn’t use at all, and the fluid is still bright red after 22K in our possession. Which brakes are undersized? The front caliper has two pistons, with good pads those are big enough to stop this 4400 pound beast. BTW, I didnt have to change the rotors. It stops smoothly.
