 I just got back from trip from Ohio to D.C. At some point I was not sure if the car will make it back. Cruise control actually won't control a car while driving down the hill (long downhill areas in PA state if you don't take I-70 toll). On up-hill driving the transmission is slipping (with and without cruise control). It was slipping this morning too while driving on flat surface. It didn't happen before. I took Jetta to VW dealer and "they will investigate it... but most likely this is nothing... ". This is third dealer. Two dealers didn't want to take a car and didn't want to "investigate" the transmission issue. So, I've got "nothing" and I am just wasting people's time? Another issue: Front Rotors are made of cheap metal and it will wobble. I am leasing Jetta because I wanted to see if they fixed previous issues. VW didn't. VW is still just a neat looking car with low reliability. I need to talk to someone with same issue! Random JettaTSI drivers I've talked to, all had manual transmission because they did have Automatic transmission failures in the past. This is my first VW. Why would you buy another VW if it failed? Hope this car will break and I'll end up the lease and I'll get Japanese car. One more thing: do not use synthetic Mobil because it won't like it. Search for dealer with oil change coupons instead (here in D.C. it's $46 - same you will spend at Walmart plus your time). Dealer has good oil. Good oil is important for these engines because VW has plastic parts inside such as chain tensioner. How long will this part last?
