Accent 1.4L A/T Engine Knock Now Due to CVVT Defect. (According sa Casa)

[bratski]

Yung accent ko wala na gaanong engine knock after replacing the ecu and then upgrading, sa 93 octane nag knock parin slightly. But 95 octane above almost non existent na ang knock. Fuel economy medyo masama pa rin but it's improving. Nasa 6.5km/l na ako city driving.

Parehas lang po ng sa sister ko. Nag-complain po ba kayo sa DTI about this?

UPDATE: HARI has replaced the whole CVVT system of my sister's Accent free if charge since its still covered by warranty. Currently she's testing it. No engine knocks were heared/felt even if 93 octane gas was used. A/T is upshifting around 1,700-2000 rpm. Fuel consumption is better. Well looks like the CVVT is the culprit.

Thanks for all your help.

Wow! finally, may solution na ang hyundai! sana ma palitan lahat ng sablay na cvvt.

That's an expensive fix. If they had to replace the mechanical portion of it, that means that it was not activating/deactivating properly due to some alignment issues.

That's a sucky-expensive fix if you have to pay for it!

Sirs,

So since CVVT ang cause ng engine knocks will these knocks shorten the life of the engine? or the knocks due to the replaced defective CVVT parts with no effect to the engine life? Thanks.

Lesson: avoid a 2011 Accent in the 2nd hand market

If it is a design flaw, Hyundai should issue an immediate recall before things truly get ugly. That is a gosh dang expensive fix out of pocket. Apparently, not every '11 and up Accent has issues. I find that if you know of a reputable gas station with untainted gas, stick with that one or else you are taking a risk when you gas up some place else. I learned the hard way but that is what I recommend if you are having the symptoms..it fixed my power lag issue.

Bottom line, Hyundai is not as reputable as people are led to believe but sadly it is pretty common in the automotive world.

Just bring it to any Hyundai casa. Before palitan CVVT mo for sure dadaan ka muna sa "Compulsory Primary Procedure" (ECU updates, karga ka lang dapat ng Shell 97 octane gas, ECU replacement, etc...) tapos pag hindi ka na mapaikot at nagbanta ka na ng lawsuit or DTI complaint (and also kasama na after around 20,000 kms of religious PMS) ay tsaka palang isa-suggest CVVT replacement.
