Accent LC (2000-05) :: 2003 - Rattle Sound On Acceleration / Load
Sep 10, 2011
My '03 gives a rattle sound under load/acceleration conditions. This does not happen during the warm up period, so it appears that the engine runs lean under acceleration. There is no check engine light on for this. Approx 172k KM, (100k miles). The noise appears worse when it is hot/humid outside. I have run a can of Seafoam through it (half in the crankcase, half in the fuel line), and that doesn't seem to have worked. Therefore, I don't think that it is the injectors. Possibly fuel filter (still original)? Any easy way to test?

We've got a 2012 Hyundai Accent GDI. I've been hearing the rattle "ping" when the engine is under load (accelerating hard or uphill). I've read that this is typical for these engines.
I took it to our local Hyundai dealership since it's still under the 60,000 mile warranty. They updated the computer settings and I put in a fuel additive to clean up deposits. They also told me to buy name brand gas from here on out (Exxon, Shell, Mobil) as these engines don't handle cheap gas well.
Now that I've given you enough of a backstory, here are my questions:
- For those that have experienced the rattle "ping", what did you find fixed the problem?
- Any tips or things to look out for when cleaning the throttle body etc?

Today I drove my 2006 G2 Prius with 59,000 miles to the park and had the windows down. I climbed a hill for a good while that had the engine under load and there was a concrete wall beside me, and I could hear a very very faint metallic-like rattle. I mentioned it to my partner who listened and said he couldn't even hear it, so maybe it is just me.

My gfs car (2012 accent) makes a rattle but more specifically it makes this rattle in about 3 gear under acceleration but not heavy acceleration (slow accelerate in a higher gear) at about 1500-2k rpm it makes a rattle and if i really get on it in the gear it keeps going, the second i let off then get back on (lightly) no noise but when you depress the pedal a little hard it does it again (auto trans by the way) I've heard of this before only issue is I don't remember where or who (useless, and wasn't a hyundai accent) anyway anything would be useful, car isn't under warranty so trying to stay out of dealership...

I have a 2000 hyundai accent 5 speed with 76k and a 1.5. the spark plug boots arc on all 4 plugs and can see a light blue line down the center of the wires also. But while idling you see nothing till u snap the throttle. Also driving while its under load you can really feel the miss in 3rd gear. Ok here"s what I've done I cleaned up all my grounds on motor and body ,also cleaned spark plug threads. i replaced wires with 5 different brands including factory wires and same thing. I've tried all kinds of different plugs from regular coppers to iridium and changing plug gaps with no change. the coil was replaced,crank sensor changed and does same thing.

2002 Hyundia Accent -- 1.6 DOHC 2D
When I get to 2700-2900 RPM Under load my car will chug out (basically lose power all together for a brief second) then it will come back and chug out again. I am able to max out RPM's while doing this however under load it still chugs along. WHEN not under load it rev's up fine and purr's like a kitten.
So I went and got a new motor for this car same model as was in the car before a 1.6 DOHC. However upon replacing it (also attached still was the timing belt and clutch assembly, never taken off)
So it seems to be getting spark just fine. and I replaced the MAP sensor thinking it was a intake issue however still problem exists when I am under load between 2700 - 2900 RPM it bogs out for a second losing all power.

Had this happen to me a few times now. Driving down the highway (120kph) in 5th, revving around 3,000 or so and whenever I hit a hill and come onto the gas pedal, I hear a ticking sound coming from up front. The harder I press on the gas - the louder it gets and vice versa.
Only happens in 5th and only under load. Scanned for codes - nothing, looked under the hood - looks normal. Timing belt was done around 56,000km, car has about 67,000km now and is in fantastic shape otherwise.
Spark plugs are still original and I have a new set waiting to go in, drive belts were replaced back in the spring but the tension is correct and all pulleys were checked okay at the time.

2003 Hyundai accent GL 5spd has new rings/bearings/lifters and all gaskets (when i got the vehicle it over heated to the point it shut off ) figured it was just a head gasket so replaced it found out rings were shot.. so that's the jist of it. okay so she's timed right spot on but when I go crank up the car it cranks over fast and i have to feather the throttle to get it to startup the IAC makes a weird buzzing sound and wouldn't idle right so i unplugged it and it'll idle fine. When it would finally crank up and idle she drives really well put about 20 miles on her so far just the starting issue pissing me off. I'll post a vid of it trying to start for better description...

I've got a 97 truck, broke the crank, swapped in a motor from an 07. Heads down is 07, intake up is 97. had heads planed and a valve job with new seals done. Left it alone from the rings down. Got it in this weekend, running today. Ran it in the driveway with no load for about 30 minutes, top end was noisy for about 5 minutes till the top end got good and oily (I'm assuming). Purred like a kitten, sounded real smooth. Took it for a drive around the block, heard the clatter in the video below. It's almost always there when driving. Brought it back, turned it off to check oil, it was a quart low. Added oil, startup was VERY labored with a real hard knock in the bottom end. Ran like poo till I gave it some throttle for a couple seconds, then it cleaned up and idled well. Let it run for a couple minutes, turned off and let it sit for a couple minutes then started back up, same thing. Very labored with hard knocking.

I've noticed lately that my mileage and performance of my 2012 GLS has gone down. I can hear a "clicking" sound from the right side of the motor when the engine is slightly under load almost like a cam shaft that's operating without oil. I've done all the obvious things like check fluid levels and the such. My car has about 130,000km or 80000 miles on it.

So I'm experiencing a very irritating rattle at about 2000rpm under acceleration. I've only noticed it in sport mode. Seems to be coming from the front of the center console.

I have a 2000 accent. Automatic tranny with 167000 miles. My current problem is the car is misfiring upon acceleration and engine revving. I have to accelerate very slowly to minimize this but i once the engine revs up enough I can give it more gas and it will rev normally with plenty of power. I have had to unplug the maf to keep it driveable. Ive never had a car stay running after disconnecting the maf so this is strange to me. My accent barely stays running with the maf connected. I just got the car from my dad and he had it fixed and it ran good for awhile with the maf connected so I don't think it is the maf. But the same problem came about and we had to disconnect the maf again. And he cant remember or is not sure what was exactly fixed on the car. I've read up about the purge control valve and havent had a chance to check it out but some of the symptoms fit.

I'm back with another question! My 2006 Prius now has 60,XXX miles and the other day while driving with the windows down, I was climbing a hill to my house and when the engine is at a certain RPM, there is a metallic sound that comes from under the car, but more in the front. You can't even hear it when the windows are up barley, but more when they are down, you can hear it, especially when you're beside a wall or guard rail and the sound can reverberate back.

[URL] .... You have to crank your speakers to hear properly, the mic in my phone was trying to cancel the engine noise I think... Someone suggested an exhaust hanger in another thread, I still have to get under the car next oil change and check that.

When ever I hit a bump, the front passenger side around the front wheel area rattles but doesn't when i brake, could that be covered under the 10 yr? Our car only has around 36,000 miles on it .

I just got my wife a 2000 Echo with 224,000kms on the odo. Everything appears to be fine other than a mystery rattling noise under light acceleration. If I were to describe it, it sounds as if a box of rocks were to be shaken around. Or like a rattling loose chain... <------ definitely hope it's not that!
From a search, it seems like others have encountered this strange noise but have not reach what the cause is.
From what I gather, the timing chains on these motors are literally never touched and should last the life of the vehicle.

Was hauling a bobcat this AM and noticed something odd in my rear view. Under steady accelleration (either light or heavy foot pedal pressure - steady either way), the exhaust would puff out sporadic extreme dark clouds of smoke. The puffs weren't fast like every cylinder rotation.. but every second or so.. puff of very thick black smoke mixed in with the expected black smoke we see.
Truck has 350k miles with regular oil changes. Year ago someone hooked the injectors up to the computer software (buzz test) and all of them checked out to be in very good condition.
The same tech pointed out some dark blowby at the uppipe on the back of the engine. Other than that the truck is in pretty good condition for its age. What could the sporadic very thick/dark puffs of black smoke indicate?

Last weekend on my way home from work, I heard this small "thump" noise then a rattling noise started. It really sounds like spinning a marble in a plastic bottle.
I got the car checked and we got code 0734 (Gear 4 ratio incorrect). We think there might be a tooth missing on the gear, but the mechanic wasn't entirely sure, as he wasn't a transmission specialist.
Now, I fear this may cost me my first born child, and I might just end up buying a cheap car for the Winter and get rid of this one; the transmission repair costs are ridiculous.
I've been driving the car in the city (30-50 km/h at most), I'm trying to avoid the highway, I'm afraid I'll blow it, who knows.
It has an automatic transmission, with 125,000 km on it, 2003 make.
The noise only happens when the car is moving forward, not when idling/parked, not in reverse. I am very gentle with the car, no highway speeding, no sudden speeding. I did however do an oil change a little over a month ago, and read somewhere on here that if the wrong fluid was used during maintenance that it could cause problems. I will call the shop and ask them about it.
