It's an admirable attempt to save this technology but kind of funny at the same time. Personally, I think their R&D funds would be better utilized in proofing out HCCI or just moving to electrified powertrains. Volvo is doing the latter since they have far less resources to call on and understand that we have come very close to reaching peak efficiency with the internal combustion engineAnd the gent that said no one has figured out the GDI intake valve issue - well at least Toyota Ford and Infiniti have and are attempting to do so utilizing DI and PI .
It shouldn't and that is more of a Hyundai management issue than even an engineering one. Recall the story about the Hyundai whistleblower who told management that Theta II had a design issue prior to the release of the YF Sonata. Yet Hyundai release the car to the public with the flaw then blame owners for not maintaining the car when the engine failed. The company culture is to blame here fullyYes I can understand happiness in getting a refurb block and engine fixed for free - but really should this be happening in the 1st place - all from a "change in the cleaning process"
Luckily the recall seems to be open ended and they are retesting vehicles multiple times prior to failing. If its cold wher you live listen hard at cold start...sounds like piston slap but it will progress to bearing failure with time. Just like mine did.I have my fingers crossed my powerplant will blow before Hyundai closes out the recall.
Maybe Hyundai will get the Theta III design correct.
And Theta III wont happen. Hyundai will most likely move the lineup to even smaller displacement turbo engines (i.e. the 1.6t that is already in the Sonata) just like everyone else, call all usage severe duty, and dodge warranty claims by claiming owner neglect until the next huge batch of failures. Then issue a recall under government scrutiny with bogus test procedure and say its fixed. Business as usual
