Well this is my first time posting in the Gen 4 group. I had a Gen 3 2015 for about 8 years. I had no issues and I ended up trading it in with about 350,000 mi. My Gen 3 came from Tampa hybrids which I highly recommend! I found a Gen 4 there at a good price and decided to make the switch. What have they changed in the Gen 4 from the Gen 3? The ride is so much more solid! The car is so much more refined. If I didn't know this was a Prius at this point I would think it was a Lexus. My Gen 3 I kept up with the maintenance basically put a new suspension on that bad boy. It was never as quiet or as solid feeling as this car. The 2015 never had an trouble codes. Just asking this question on what changed from 2015 to 2018. Of course I'm going to search in Prius chat to see if there's anything listed. Thank you for your time! Paul
