Car is like two years old only 25,000 miles! That’s insane to have three failures.
Throwing in my 2 cents but there’s something else going on there for sure. It’s a part that very rarely just fails on its own (especially repeatedly) and the culprit can be a very expensive fix (cylinder misfires, bad spark, low compression, burning oil, etc.) It's either getting excessive heat or clogging. They need to get rid of the car or figure it out before it’s beyond the warranty period. My guess is the dealer keeps throwing one on so they don’t have fix the source of the issue.
