We just bought our odyssey last month (125k miles) and I have noticed a few things I missed while test driving it.
1. Every time you drive the car (after a fresh start) it will give a soft crunch while shifting from first to second. It will not do it again until the van is shut off and started again.
2. There is a high pitch whine around 30 mph and up. It will stop if I lift the accelerator but will continue once I press the gas again.
I purchased a warranty and I hope everything breaks within the next 2 years

. Do these sound like regular issues with these vans?
