#TechnicalServiceBulletin

We told you recently of the tsunami of complaints from Ford Focus RS owners swamping the National Highway Traffic Safety Administration — and other agencies — with minor gripes like, say, their brand new car burning engine coolant. Well, there’s a fix afoot.

In a recently released service bulletin, Ford describes the issue plaguing its hottest hatch and vows to replace every cylinder head installed in a Focus RS built between August 3, 2015 to July 6, 2017. That is to say all of them.

Hello Sajeev,

Conventional wisdom says wait until the second model year of a new vehicle since that’s when the automaker will have fixed the glaring flaws decried by the “beta testers” who bought the first model year. Is this always true?

Do automakers fix problems “on the sly” so that, say, a 2016 model year car manufactured in August 2015 could already incorporate some/all fixes slated for 2017 model year?
