I bought my 2010 Jetta in May 2010. It is my second Jetta and 4th VW/Audi product I've owned. By far this is the best Jetta ever made. The 2010 includes many improvements over the 2009 and earlier models. The seats were given my cusion making them even more supportive. The lumbar is very good. User interface ergonomics are excellent. Interior build materials are on par with premium level vehicles. The Mk. V Jetta compares well against the likes of the Mercede-Benz C-230. The standard audio system is 8 speakers with excellent sound quality. Sunroof is smooth and quick. Everything is right where is should be in this car. It is a joy to drive or ride in around town or cross country.
Just leased the 2010 LE automatic last week. I have to admit this is one fun car to drive. Fit and finish are on par with BMW and Mercedes. I just came off of a 5 series BMW lease, and my wife drives a 300 AWL Benz. I actually prefer the ride of the Jetta to the Benz. Not quite a challenge to the BMW's handling and performance, but for less than half the price it's a pretty good trade off. The cabin is extremely quiet, even over rough pavement, and the car corners through turns very confidently with just modest body roll. Acceleration is reasonably quick. The car has a heftier feel to it which belies it's actual weight. This translates into what feels like a more substantial road presence.
The day after I bought the car the passenger seat got stuck laying flat (my daughter was laying down for 5 minutes while I went into the bank). The electrical system continually goes bad and the car will not start. 2 years in I had to replace the air conditioner. The trunk broke two weeks after I bought the car. I back the car up out of the driveway and it continually stalls out. The oil light never comes on even if the oil is low. I have to replace the headlights and back lights every other month. The Dealership is horrific and I never go there because I am treated so poorly. I pray everyday for something to not go wrong with this car, because it seemingly does.
This isn't our first VW Jetta. Although, we did test drive quite a lot of cars before purchasing this one. Amongst the cars we did not purchase Audi A4, BMW 325, Hyundai Sonata, Toyota Camry, Honda Accord and Mercedes C Series. A lot of these cars had nice features, some more than others. None put it all together with a manual, a great engine and a fair price tag like VW had. We are very proud owners of these vehicle. So much so, that we purchased the 100k mile warranty. Its a keeper.
The 2.0Tsi engine has a known "popping sound" at between 2000 and 3000 RPM. Many owners complain of the noise during acceleration, sounds like "pop rocks in a can" - I thought it sounded like engine knocking. VW confirms it is the wastegate on the turbo, but says it is normal. Along with the noise, I find it annoying that they have known about the noise for at least three years yet have not fixed it. Test drive with a purpose and make sure you can stand the noise before buying, because you are stuck with it once you take the keys.
