2011 Accent AT - Engine Knock!

[tidus1203]

Saan kayang petron branch to. Para maiwasan.. Gusto ko p man din i try Petron. Puro shell unleaded kasi ako eh...

Eh diba Fiesta ka? Ok lang Petron satin in fact yun lagi gamit ko (yung pinaka mura yung Xtra Unleaded) since I feel I get better mileage with them at least sa FoFi.

Personally, I don't think its the fuel... Its one of those quick but unfounded answers by car dealers just for the sake of having an answer.

[number001]

Btw, the TS (and the zackek guy) tried all manner of fuels (shell and petron) yet the symptoms still persisted.


On a lighter note, fuel should not be an issue here....unless the spin doctors at Toyota Phils has found new jobs at HARI.

baka may sira nga ang engine, ako Petron Xtra Unleaded mula nung nakuha ko unit at turning 3 months this may, wala naman ako naririnig na maingay sa engine, tahimik nga eh..

[tradewind26]

Oh. Ayos naman pala petron. Mukhang engine nga yan. Pa check mo sa labas pag insist ng Casa na walang problem. Ayaw lang nila mag repair eh. Kaya kung anu-anung reason sinasabi nila

Sir, ask ko lang, sa umaga ba pag cold start tahimik makina mo? di ba sya dieseling?

[airolynx]

Sir, ask ko lang, sa umaga ba pag cold start tahimik makina mo? di ba sya dieseling?

usually sir yung maingay sa umaga is because your engine idles faster than it should during cold starts. this is to help the engine warm up faster.

the higher noise level may also be due to the oil not yet reaching some parts of the engine.

[batang_raon14]

Thought I'd add, stated on the manual 95 RON ang kailangan talaga ng Accent pero for EU countries lang daw ito. For non-EU countries, pwede raw ang 93 RON but expect degradation in engine performance daw.

You can check it in the manual to verify.

tama, pero once mainit na makina at nag full stop ka, tahimik lang..

inaabangan ko ang thread na ito kasi i'm also hearing slight engine knock sa tucson theta engine ko since 1k pms. 11k na tinakbo ng engine ko pero nandun pa rin from time to time un tope and maybe nasanay na ako sa sound ng engine. ilan beses na ko nagpabalik balik sa casa but ang lagi lang sinasabi is normal lang daw yun sound ng engine. mismong service manager na nagtestdrive. wala rin makita na abnormal readings sa GDS and lahat ng parameters pasok sa spec.

sana may makita ang casa or HARI na solution for this or claim na engine noise is inherent sa Hyundai engines.

mas ok siguro magcompare ng engine sound side by side para malaman if normal lang din ang noise... or better yun TS magtestdrive ng ibang unit for direct comparison. wala pa lang din ako natestdrive na ibang tucson to check.

What kind(s) of fuel do you or did you use on your Tucson?

[harold13]

make sure na ok yung gas station na pagkakargahan na lang.

Tucson naman ngayon????

Ok yun Sir, inherent na knocking sound sa Hyundai engines, baka bagong pa uso ng hyundai, instead of the vrooom vrooom sound eh knocking sound na ngayon sa mga brand new units.

Joke or not, its interesting to know how will Hyundai answer all this, ang kawawa lang talaga ay tayong mga consumers, dahil sa PALPAK na reasoning nila.

Para naring sinabi nila, bawal magpa gas sa petron ha, dahil masisira ang unit mo...........

Ano ba iyan? Pati Tucson, may posibleng parehong problema...

thanks to all the responses i got from you guys!

my friend who got his White Accent MT last January from E-Rod reported of engine knock at E-Rod casa after using petron unleaded. He claims the knock is cured by petron XCS. (third accent i guess with engine knock). mine apparently was not cured by XCS.

Update as of today:

it's my 5th gas-up using Shell Unleaded. Engine seems to be ok now. almost no knocking sound. I could easily reproduce the knock sound BEFORE, but now it's almost gone. *almost because i get surprised sometimes hearing a very short knock. I'm hoping the new spark plugs will solve this.

I went on a short road trip today, with 3 friends so the car is loaded. along the way i ask them to spot a knock. we didnt experience any. perfect day na sana pero nung pauwi na ako and mag isa nalang, a knock occured briefly. after that wala na. i hope i'm on the road to solving this than face the gruesome task of claiming for warranty.

i'm thinking of changing to shell premium hoping to see more improvements. any of your thoughts is appreciated.

*** to the moderators, i still think this is not yet fuel related but feel free to move this thread if needed. thank you very much.

[CVT]

For that class of car, you should be able to fuel-up on any gas station using any petrol variant....

Hyundai should urgently solve this issue....

san niyo kaya yan sir pinacheck? saang casa? para naman ang tagal bago nila masupply ang kailangan na spark plugs...

[harold13]

This engine knock happened two days ago with our 2 month old Accent 1.4L A/T. For fear of running out of gas kasi malayo pa Shell Service Station, did what one would do under the circumstance, gas up at the nearest fuel station I could find, which was MOBAN (this station should be BANNED since they sell crap for fuel). I even casually asked the attendant how their fuel is and kung merong tubig ang gasolina nila and all that nonsense chit chat to which he replied, "Petron 'to"..must be referring to their fuel supplier. I didn't notice or hear the engine knocking sound since I was excited to listen to music I downloaded to my USB the night before and AC was on number 2 or perhaps it was the anticipation of a long (2.5hr) trip to Sorsogon City which also made me unaware of the situation underfoot. We heard it on our return trip and was very erratic and pronounced. Me and the wife kinda looked at each other in total disgust at how our brand spanking new car is making that sound when I wasn't doing anything but stepping on the gas pedal. I even called my agent midtrip to let him know about the issue and and advised me to bring the car to the casa in the morning so they can check and since it wasn't affecting driveability of the car, we proceeded home. The next day, we gassed up Shell with Unleaded and somehow didn't notice this knock. We even gassed up at Petron with XCS and problem seemed to have faded away. I am going to continue to monitor this Accent issue and let y'all know.
