Vulcan 3.0L camshaft position sensors that fail 100% of the time just outside the warranty period.
An A/C condensor placed just above the oil filter, making a standing oil change impossible, when the previous model year routed it a few inches forward making filter changes fast and easy.
Belts, hoses, water pump, nuts and bolts hard up against the firewall or fender well wall.
Replacing a dealer-only $120 A/C valve with a $435 valve and hose assembly.
Flex/rotating A/C hose that leaks, new or old.
An engine control system that can give the engine throttle, and does so at bizarre times, like on each upshift, so a car left to coast on a level surface at 5MPH will be doing 50MPH in a minute w/o touching the pedal, and the dealer says that's perfectly normal, mine is just a little more aggressive than most.
A transmission that stays in top gear until nearly stopped, giving zero compression braking, and dealer says that's perfectly normal.
Replacing front rotors and pads every 18-24 months because of bizarre transmission and throttle behavior described above.
A front end that cannot go more than 18 months without needing at least one of: ball joints, tie rod ends, sway bar end links. bushings, or other front end component.
A car with 100% failure rate of the rack and pinion steering within 150K miles, from a personal survey of a dozen friends, family and coworkers that owned the same vehicle.
A car with 100% failure rate of the A/C system within 120K miles, from a personal survey of a dozen friends, family and coworkers that owned the same vehicle.
A car where you cannot get keys or remotes made at the dealer after 10 years, because their VIN/keycode database doesn't go back that far.
A car where the first water pump lasts over 100K miles, but new pumps bought at the dealer last only 20K/2 years each.
A car where the starter must have been considered a permanent install, so the SOP for replacing it involves cutting and splicing the solenoid wire.
A car that cannot get through any 6 month period of time without $600-$1200 worth of repairs ($100-$600 DIY cost).
OK, so those are not really "Auto industry complaints" so much as '99 Ford Taurus complaints. Now ask me which brand I don't buy any more.
