My daughter drove my 2015 Pilot in D2 on the highway nonstop for over 100 miles on a trip last month. She said the a/c 'stopped cooling' above 60 mph, and she maintained that speed because the engine sound was really loud. but didn't notice what the tach was reading. Surprisingly, it ran fine for the rest of the 3000 mile trip and seems to be running fine since. Is there any way there's no damage?

 

Is there any way there's no damage?

If the engine rev or rpm did not exceed the redline and the oil level was good then good chance everything will be okay
AC is a different issue

 

pilot engine has a rev limit so it will not over rev. oil just used a little bit harder but if the temp did not get hot, should be no damage. the a/c may have stopped due to freon leak, need to get it checked. check engine oil life and continue to change oil as needed. also check trans fluid due to trans was run a bit harder than normal.
