According to the data, overall vehicle dependability averaged 133 PP100, a 6 percent increase in problems from the 126 PP100 average in 2013. This marks the first time since the 1998 study that the average number of problems has increased. The researchers cite the increased number of downsized turbocharged engines and diesels as being the main cause for the increase in problems.
In fact, most of the additional problems were in the drivetrain department, with a lot more owners complaining about engines being too noisy or having inadequate power, and transmissions that were rough. Though these may not actually be defects, if not addressed owner perception of a brand may change--the researchers have discovered a direct correlation between dependability and brand loyalty (from vehicle trade-in data).
