I have a 2018 Honda Civic
I have a 2018 Honda Civic Touring with less than 30k miles. I have changed the oil when prompted by the car, three times now at approximately every 8k miles. The fourth oil change was prompted at only 4K miles. I noticed the oil was very dark and the reservoir was over full. Now my car is showing multiple errors with the breaking system and transmission. It seems to drive okay, but I am worried.
