I bought My 2023 Honda Grom at my local dealership on February 9th 2023 , brand new 0 miles. Around the 400 mile mark I noticed a "whining" sound after a long period of driving in 5th and in 4th gear. If you engine brake and down shift to 3rd or 2nd gear the noise goes away immediately. It only happens on occasion it doesn't do it all the time. I did purchase the 5 year warranty on motor and transmission. I did my oil changed at 600 miles with all OEM Honda parts and Fluids. The noise is still the same at 1000 miles. On May 10th 2023 I took the bike into the dealership but they said a mechanic would test drive it but I told them the bike has to be driven for an extended period of time in order to replicate the issue. The said they are not allowed to drive long distance, so chance is the issue would not come up. I was also offered to have the transmission looked at and taken apart for 260.00 if they found the issue since I have warranty that the cost would be waived. But if no issue was found that I have to pay the 260. I did not leave the bike for service, I am waiting to see if this is a recall, there are many people on the Honda Grom communities complaining about the SAME EXACT issues. Type in Third Gen Grom Transmission issue , or Honda Grom Transmission issue in Google and there are endless post about it. Some people are going as far as saying Honda is waiting for something to snap and rear tire to lock up which obviously I hope does not happen to anyone. I hope this concern reaches someone and it is resolved soon.
