Hooniverse Asks- What Was the Worst Automotive Engineering Feature Ever Introduced?

The automotive engineering foisted on the public has, over the years, been pretty hit or miss. For every direct injection there’s a talking dashboard. Ford’s external keypad is pretty brilliant, while Cadillac’s attempt to fool buyers of its cars into driving four cylinder when they  coulda’ had a V8 is one of the most noteworthy of failures. Diesel engines engineered from weak-kneed gas progenitors, hydraulic everything, airbag suspension, lights that turn with the tires, massage seats, there’ve been an encyclopedic quantity of engineering solutions for problems both real and imagined – and some of them sucked.
Sure, some may have been more ahead of their time than ticking time bombs, but others have eventually grenaded on their owners, ensuring a place in history’s pantheon of questionable executions. Was the Chevy Avalanche’s Rubik’s Cude of a mid-panel a good idea, or the tool of the devil? How about the JDM Honda Del Sol’s automatic targa retractor – complicated, weight-adding and kept at home because the Japanese are notably less litigious when it comes to  product failures?
What do you think, is one of these engineering marvels on the top of your list of craptacular automotive solutions looking for a problem to solve? Which automotive engineering feature strikes you as the worst ever?
