I purchased a 2020 HEV three weeks ago and have put 1000 km on it. Today I got the "check active air flap" message and CEL came on. Took it to dealer 2 hours later and everything was good until I arrived and then message and CEL were back. Tech checked it out and said everything is OK and sent me back home. I am skeptical that it is fixed but certainly going to drive until message returns and I get sick of ignoring it.Our error message came back but we are ignoring it as per our plan. I’ll be interested if this latest replacement works for you or whether you will eventually get the warning again.
