I have 2019 EXL and It already has 240k miles on its odometer.
I don’t trust stealer-ship advices (long story short transmission grinding problem started 200k miles ago and 4 different states’ stealerships performed diagnostics and couldn’t find any issues but it’s grinding!!! and my solution is when grinding starts (only on D mode): foot off the gas pedal, shift to N, wait until stable rpm and shift to S mode and continue driving) so I thought someone here can help.
I am driving cross country and also I have long idling times. So I am thinking this engine needs some kind of cleaning/maintenance since it burned more than 11k gallons of gas.
can you advise me what to do and maybe good mechanic referral?
