This might be an unknown issue, but upon startup, the brake pedal is very stiff and hard. Few times, I couldn't start the car because the brake was so stiff, I couldn't press on it with my foot, and it went into accessory mode. I took it to 3 different dealers, they keep telling me that it's normal. Advantage Honda tried replacing the battery, but that didn't help. All they could do is a multipoint diagnostic on it, where the computer won't show anything. Dealers are telling me it's normal, but why is my neighbor's 2017 Honda Pilot not giving him the same problem" it can't be normal because when I first purchased the car in Aug. 2017, and up until mid Oct. 2017, the brake pedal was fine. Then after that, it only happen overnight, then now it's happening every time I start the car, it gets very frustrating when you have to slam the btrake pedal in order to start the car. I've driven other vehicles with push button starts for many years in the past, and I've never encountered an issue like this. Could this be an issue with the hydraulic brake system loosing vacuum supply where dealers don't want to bother taking a closer look at the issue because they don't make that much money if it's still under warranty" I've called Honda of America, they told me to bring it to a dealer, but dealers are not helping or even explain why is the brake pedal doing that other than say it's normal. As soon as I start the car, the car runs fine. Please help me understand why my car is like this. Thank you for your help.
