Taking a page out of Maslow's book (study healthy people not just sick people) can people who have NOT had known CBU issues pipe up?
I'm at 43K miles and have had no problems and no drop-off in mileage, but given the common onset around 50K I do not place much significance in that.
Please be sure to state your model year and mileage.
Thanks in advance.
