“The switch some time not detect, and do not start. Need to turn several time to start the engine. Once it start no problem. Some time in the morning it start without any problem. The dealer told me it is a ignition problem, the car mileage is only 87000. When I searched in the internet, 1000 of customers reported the same problem for 2010 and 2011 model cars.”
NHTSA complaint #11002473, filed 2017-06, 87,000 miles“Was driving to work on the highway in the rain and the truck jerked over to the right without me doing it. Its happened three more times since then. The dealership cannot duplicate the problem so therefore there is no problem. My ignition switch needed to be replaced at 20,000 miles. My keys would not start the truck for an entire week straight on the 1st or 2nd attempt. Finally on the 3rd try the truck would start. Its a year and a half old. When they connected it to they're computer it did not read any error codes. It had to not start there for it to code. …”
