No matter what it is, somebody is going to get the lemon. My 4-Runner was just that. When going down a flat road in cruise control, or manual control, it would start downshifting into drive and then back up to overdrive. Then it started doing something else, which was downshifting from gear to gear when I took my foot off the gas, just like I was yanking the shift lever. Both problems were intermittant, and all the Toyota guys said "They had to be in the truck when it was doing it for them to know what was causing it." BS of course. I finally left it with the dealership and told them to let somebody drive it around just like it was theirs. They finally called and said one of their mechanics was driving it when it did the downshifting thing. I said "Hot dog, now your're going to fix my truck." They said "No, your engine needs a tuneup." I replied "Let me guess, then we start all over again." Silence on the other end. So I took them to arbitration and the BBB made them buy it back at a very good price. I had my son in the truck with a video camera focused on the speedometer and tach when it acted up, so the arbitrator thought that was good evidence.
