I just purchased my very first minivan, a 2007 Honda Odyssey EX-L. I drove it 50 miles and the engine light and "D" (for Drive) light started flashing at me. I immediately took it back to the dealer. They returned the car to me 2 days later saying it was the 3rd gear pressure switch, which they replaced. I drove the car two more days and again both lights came back on. The dealership has had the vehicle now for an additional week and has put over 200 MORE miles on it to try to 'fix' the problem. They've flushed the transmission twice and traces some electrical wire in an attempt to troubleshoot the problem. Have any of you experienced this with your new '07 ODY? The dealer has had the car more than I have AND driven it further than me; I am deeply concerned that I just made the biggest purchasing mistake of my life... What can I do?
