The manual transmission in the 2010 Hyundai Genesis coupe is very problematic. Very often the gear selection is rejected not allowing the operator to up shift or downshift. Second gear and fifth gear are the worse. Grinding often occurs when shifting into 2nd gear or 5th gear. I was merging into traffic on interstate 495 in massachusetts when my car would not shift into 5th gear. The transmission simply started to grind. When merging into traffic at 50-60mph an operator needs to shift from 4th to 5th and I could not. I had to quickly downshift into 4th gear to try and keep accelerating. Any shifting into 5th gear after approximately 3,400 rpms resistance and often grinding will occur. This can very easily cause an accident, expecting to be able to shift into the next higher gear and not being able to do so. I have taken my car to a Hyundai dealer and "they could not replicate the problem". I took the service tech for a ride and the car ground into 5th, and I was then told "this is normal operation of the transmission". Hyundai does not want to remedy this problem, and eventually many Genesis coupe owners with manual transmissions will be using lemon law protection to have their cars fixed.
