We have a 2018 CRV Touring
We have a 2018 CRV Touring model with the turbo engine and have had the exact same experience. We had the software updated in January as part of the recall program and immediately had a 10% reduction in fuel economy. The oil level is above the full mark and has a gasoline odour. The turbo is noisy and the tire noise excessive. All of this was brought to the attention of the dealership and Honda Canada and I was told that this was normal and they have no other reports from owners with similar issues. I guess I am just lucky.
