Hope your luck with Honda warranty on battery is better than mine. I am still fuming...I purchased a 2018 Goldwing Tour DCT end of March, 2018. I rode it almost daily. I purchased the recommended battery maintainer from the dealership, which was about 55 miles away from my home. I even paid the dealership $10 to hook up the leads to the battery during my first service. I had it serviced at 1000 miles, then again at 4000 miles. Any accessories that had been installed on the bike was done by this dealership. The only thing I have done to bike, other than ride it on an almost daily basis, was check the oil level and tire pressure. When it turned cool here, in November, 2018, I saw that I was going to have to go a couple of weeks without riding due to bad weather. I hooked it up to the battery maintainer. Everything looked good on the maintainer. All the indicator lights were showing things were correct. Then we had a nice spell of weather, so I took it off the maintainer and tried to crank it. It would turn over but not start. After multiple attempts, no cranky. I hooked it back up to maintainer and tried again the next day. No cranky. I called the dealership. I even shot a video of what bike was doing and emailed it to the service rep. They said it didnt sound like the battery, but needed to check it. Honda does not pay towing for warranty repair, so I had to agree to pay them based on mileage. It cost me $220 in towing fee for them to come and get my bike. (55 miles away). I started doing some research here and found at least 3 others that had their batteries replaced under warranty due to being defective. I called dealership and told them of others with defective batteries and they checked mine. I got a call back saying the battery tested defective and would try to get Honda to replace under warranty, but they said Honda was hard to get to replace a battery under warranty due to some doing their own installs, bike sitting for long periods of time, yadda yadda yadda. They said that due to the mileage on bike, (6300 miles at time) they knew this bike was not sitting and I bought the maintainer from them. It was now coming up on their Christmas break as they close for a week or so during holidays. I told them I would like to get my bike back before they closed. They said they had not yet been authorized to replace battery under warranty and I could pay for it up front and get bike, as bike was starting fine with new battery installed. They would reimburse me after Honda replaced battery under warranty. I agreed to this and ended up having to pay them $390 total to pick up my bike. $220 towing plus $170 for battery. Anyway, I get bike and pay. The bike has run flawlessly since then, so it definitely was the battery. Here is where things turned sour. I call dealership back to get update on the reimbursement. This was a couple of weeks after I got the bike. At that time, they had not submitted all the necessary things for the warranty replacement, which should have already been done, but they said they would do it then. Then, I get a call back a day or so later. The dealership tells me that when they were uploading the info for the warranty, that they noticed on the test ticket that when they did the initial test, it is supposed to be charged 4 hours to test. It indicated that it had "insufficient" time charged on the ticket, so they then tested it again and let it charge for longer than 4 hours. Then they checked it and it checked OK. He said that now Honda would not replace the battery under warranty. He said that he firmly believed that the battery was defective, but the choices I had was to eat the $170 and keep the new battery or I ride back up to his shop and they would refund the $170 but put the battery he believes is bad back into my motorcycle. I thought this was stupid since he said he believed it to be bad. So bottom line is, I simply went out to crank my brand new motorcycle and it would not start, and even though it was under warranty, I still had to pay $390 to get my bike running again, as Honda would not cover the battery. May change dealerships over this. I also have a case of the red ass against mother Honda. I don't know if it would be worth it to purchase an extended warranty from Honda if they are unwilling to make things right in a situation such as this. I may open up a case with Honda, but it may be too late, I don't know.
