JD Power released the 2010 VDS, which tallies reliability for 2007 model year vehicles. The study is measured by problems per 100 vehicles. For example, Porsche's score of 110 means that vehicles on average had to have 1.1 major components replaced during the 3 year period. These major components are items such as engine, transmission, or suspension parts.

For the numbers:
First number = problems per 100 vehicles
Second number = improvement or decline from the 2009 VDS problems per 100 vehicles (i.e. a -10 means the brand average was 10 fewer problems vs. 2009)
Third number = ranking improvement or decline

For those that say there is still a huge reliability gap between Ford and Toyota and Honda, statistics have been proving otherwise. All three of Ford's core brands are now in the Top 8. Lincoln has pushed ahead of Lexus, while Mercury has pushed ahead of Toyota. There is only a 13 point spread between Ford, Toyota, and Honda, which makes them statistically equal if you factor in a margin of error.
Also, the JD Power VDS studies of the last few years point to reliability improvement across the board for all manufacturers. Even Land Rover, in last place, is still only 1.4 more problems per 100 vehicles than the best-ranked Porsche. Lemons are not being built on a widespread scale anymore.
