Pontiac Aztek
For some reason, it just didn't work for the Aztek. Introduced in 2001, it's still regarded as simply a hideous odd-ball. Those who own them do love them for their undeniable utility but most car shoppers avoided the Aztek. Over its five-year production run, just 115,000 were sold.
After this, Pontiac returned to a safer design scheme that made the cars largely indistinguishable from one another but for the size. A pavement scorching Pontiac GTO looked very much like a tame Pontiac G6. Lack of any real brand identity, aside from vague aspirations to "performance", choked off the brand's value. GM announced recently it was killing off the Pontiac brand.
