  • Manual transmission
  • 27,500 miles
I have a 2009 Hyundai Sonata with a 5 speed manual transmission. On Tuesday, May 25, 2010, I was traveling on route295 South in ri when I tried to shift from 4th gear to 5th gear. I pressed my clutch in and tried to shift, the clutch never came back up and my car stalled in the middle lane of the highway. I couldn't get the clutch to come back and the car lost its speed down to about 5-10 miles per hour, if that. The person behind me went around me but the woman behind him smashed into me doing around 70mph. Her car pushed mine forward and into the next lane. My airbags never deployed. Luckily, I walked away with a bruised left arm and that was all. My husband had called our dealership a few times regarding this issue but because it didn't stick all the time, they couldn't tell us what was wrong. My car is an absolute mess right now and I don't know if it can be repaired.

The clutch on my 5 speed 2009 Hyundai Sonata is sporadically dropping to the floor and not allowing me to change gears. I was nearly hit from behind, as the car behind me assumed I'd be accelerating, but when the clutch drops (without much resistance) the linkage locks and I can't change gears. I took it to the dealer today, and he said they had no problem with it, but the after-market floor mat was causing the clutch pedal to get caught. I removed the floor mat when I went to pick-up my car (service department was closed for the day), and, in their parking lot, going from 1st to 2nd gear, the clutch pedal dropped to the floor and I could not change gears, until I hit the clutch a few more times! I went inside to complain to the sales staff. They said I had to bring it in tomorrow. Apparently, Hyundai is having lots of problems with their clutches, but they refuse to fix it, because it is costly to take apart the transmission to see what is wrong. We bought the car because of the 10-year power-train warranty! this is dangerous and is an accident waiting to happen!
