So the other day I was pulling my 2021 HRV EX into the garage, when I stopped, and put the car in Park, in order to move a few things out of the way. When I got out of the car, I heard a weird rattling sound coming from under the hood. I never heard it before while driving, since I always have the radio on or am distracted by passengers. The car has just over 26k miles on it, and I have enjoyed it the whole time. Long story short, I took the car into the dealer and they told me the belt tensioner has gone bad and needs to be replaced. Thankfully, it's covered under warranty, and the cost of just under $500 is on Honda. I'm curious now though, has there been many others with the same issue, or am I one of the few. Other than this issue, and a squeaky driver seat, I thoroughly enjoy the car.
