No I haven't contacted them. Have you ever tried to find a place where you can email your concerns to them? I just traded my 2017 Frontier Pro-4X for a 2019 one. Never mind they have done NOTHING in fifteen years to update this model, no blind spot detection, no adaptive cruise, no collision avoidance, no LED lighting. Now they have even gone cheap on what they DID have. Looks like the days of them properly undercoating their vehicles are gone. Now, the once great off-road vehicle is now a Grandpa's grocery run truck, and noisier. Even the little net over the tray behind the driver's seat is gone. The once great Japanese builder has cheaped out. They need to import from Japan again, they wouldn't put up with chipping away at quality.
