 I'm motivated to post this review in light of the news that Volkswagen installed a "defeat device" algorithm on its emissions systems for its TDI vehicles that, in short, makes it appear it emits far less nitrogen oxide during emissions testing than it does during normal driving conditions.  In short, folks, the TDI Golf and other TDI vehicles in the lineup from VW emit somewhere between 10-40 times the upper limit of acceptable (as determined by the EPA) of nitrogen oxide, a compound that is implicated in smog and worsening of pulmonary diseases such as asthma.  Volkswagen apparently did this for years.When I learned about them, I wanted to buy a TDI vehicle in 2010, waited some time and eventually happily bought a 2015 VW Golf TDI in 8/2015.  One month later in 9/2015 this issue comes to light and I find that the vehicle I bought in part for high MPG numbers inviting comparisons to some hybrids emits a huge amount of air pollutant.  And while this is an issue VW will address with the EPA, it is me, the consumer, who was deceived by the marketing of the TDI lineup which resulted in a sale for VW.  Talk about being suckered.  If it was a bad component of the suspension or something less maleficent than intentionally misleading the consumer, I would not be so hot about this.Trust me, waiting a few years to buy something and then finding out you should have waited one additional month *really* sucks.Does the car perform well?  Yes.  Do I get 39-40MPG regularly with spirited driving and 40-50% city driving miles?  Yes.  Is the interior high quality?  Yes.  Did I love it prior to the 9/2015 news reports about the emissions being hugely misrepresented?  Yes.  Is my heart broken?  Yes.  And this will result in the loss of my business for the manufacturer in the future.There are perfectly lovely Mazda 3s and Ford Focus hatches out there for you.  Edmunds rates them highly.  Buy them.  Save yourself a headache and stick it to a manufacturer that made its business over the last few years in part by intentionally misleading its customers.
