WE have a 2013 CRV and the AWD light keeps coming on. Mostly when it has been sitting in the cold. We brought the car to the dealership yesterday and they put in a relay assy., power part # 39794-SDA-A03 and a Hook, Trunk *N [at # 84662-TOA-A01ZA. Drove home no light came on. Drove today and light back on. Yesterday cost $178.88 and they say there is another TSB 15-016 that would need to be performed at an estimated cost of $631. plus tax. The car is a 2013 always garaged with 45,191 miles on it. In addition the car has been up to this point serviced by Honda. My concern is we just paid $178.88 yesterday and they want another $631+ to perform more work. Will it solve the problem and why are we having this problem. And is this really a problem. My other concern is Honda parts don't seem to last very long. We have had other issues with another CRV we own. Again low mileage and car garaged. Any suggestions.
