We have only had our 2013 Honda Pilot for two months. It has 65000 miles on it. And looked in good shape. We thought we were getting a great deal. We have had it in the shop more than six times already because of the rear differential and alignment issues. We just replaced the rear differential 2 weeks ago. But ever since it was replaced the vtm - 4 light has been on and stays on. They even tried hooking it up to the computer and shutting it off and it will not shut off. A couple days ago I got stuck in the snow during a snowstorm. My 4 wheel drive would not engage. When we first bought the vehicle we checked to see if the 4-wheel drive worked and it did. So now after the rear was replaced it does not engage and the light will not shut off. It's very stressful considering we pay over 500 a month for it. It's our first car payment and car loan so the interest rate is 20%. I'm not sure what's happening or what our options are. Please help us!!!!
