My '02 Jetta TDI has drive-by-wire as well as our (soon to be gone) Liberty CRD diesel. 152,000 miles on the TDI and never a hint of throttle problems. Everything else on the Jeep is a P.O.S. but no throttle problems either. As far as I know, I've never heard of ANY problems with the VW TDI throttle assembly aside from it just simply wearing out - then you get a "limp" mode to at least get you to a safe place.
LOL, even the FORKLIFTS I build are drive by wire! The parts can and do wear out, but they just throw a code and call time for replacement. It is just a simple dual circuit potentiometer setup.
Toyota has been infected with "Detroit-itis". They got fat, dumb and happy sitting on their a$$ and drinking sake, thinking they can keep selling cars forever based upon the reputation they developed in the 80's and 90's. I've been in a few late model Toyotas, and I've NOT been impressed with fit, finish, quality, or performance. Highly over-rated and over-priced, and they've had a lot of recent issues - the engine sludge is one I remember well. Toyota blew that off as "poor customer maintenance" for the longest time until they finally admitted there was a design problem.
We just bought a '10 Subaru Outback. Sube's sales are up over 28%. They are not without issues, either, but everything I've read shows that Subaru of America actively listens and tries to work with customers and dealers to identify, fix, and resolve issues BEFORE they turn into recalls, class action lawsuits, govermental pentalties, etc. Why? Maybe it is because they care about their customers or maybe it's simply because they aren't large enough to give the corporate finger
to everyone like Toyota.
Toyota is gonna burn for this - badly.
I forsee a few Seppuku
rituals by some Toyota execs in the near future.
And for Chrysler - they are going to have to perform miracles. The entire company culture is "as long as it makes it out of warranty" for quality and durability. Most of the time they don't even make it that far. At least GM has been coming out with some pretty good stuff the last few years. What has Chrysler done???
