Hi
I had my right indicator light fixed at Acura dealership. When I got car back, the D5 light was blinking so I brought it back immediately, like within 5 mins. Finally they said it was fixed, I got my car back again and it was fine until about 2 weeks later it is now back to flashing again. No other issues while driving. They said they fixed one of the switches (I think 4th) and now another could have failed.
Should I expect to be charged? Shouldnt they have changed the 3d and 4th switch? What should I expect to hear as possible issues?

2004 MDX 278,000km original transmission
thanks
