Took my 2021 SE to get “whistle” / “high pitch” noise from heater blower fixed. 33k miles, been driving it 18 months.
After I got the Pilot Friday night I immediately noticed some major differences with the engine being more rough and a sporadic rattle noise behind steering wheel which I was able to replicate and record. The engine is louder when starting and feels more rough. Kinda feels as if it is always in Sport mode while on D. The rattling can be reproduced while stopped, on Drive and turning the steering wheel.
On Saturday the same behavior. Was taking a trip on the Pilot and wife asked if the Pilot was safe given how it sounded and felt. Lots of slight vibrations also while approaching idle. I could feel slight vibration on driver seat. My teen son said it sounded kinda “cool” with the strong base sound from muffler.
Then Saturday night on the way home everything literally and magically got back to normal - nice and smooth, quiet startup, no vibrations and no rattling noise from behind steering.
Sunday still drives great. All normal. Love my Pilot. Drives great and smooth.
Anyone experience anything like this? Any theories on what could have happened?
One theory is if software updates were applied that changed the behavior, but then it auto resolved. Or some type of CPU reset requiring transmission to re-learn, if that’s a thing.
Thanks in advance.
