Accent MC (2006-11) :: Engine Dies During Gear Shift Especially With AC Turned On
It is a bit 'of time that my engine have some loss of power with bumps that is not much noticeable and, for now, only just annoying while driving. But lately it has happened that, especially with the AC turned on, the engine dies during gear shift. I noticed that when this happens, the engine rpms drops more fast than normal, causing rough idle for 3-4 seconds (it go down to ~4-500 rpm) and subsequent automatic acceleration from the ecu to ~1200 rpm to settle again to the normal idle (~700 rpm). When this happens if the AC is on, sometimes the engine dies.
I checked the idle control valve and it work good and it's clean. The spark plugs have less than 5000 km, spark wire are good and also coils are in line with the reference values, Primary Coil 0.87 Ω 10% at 20 C (68 F), Secondary Coil 13.0 kΩ 15% at 20 C (68 F) (I don't have the coil on plug but external coil version, like this: [URL] ....)
The only thing a bit 'strange that I noticed is that the throttle position sensor has a strange range when i check it with an obd2 scanner. The idle % reported is 8,7% and at full throttle is 87,5%. I never removed or changed this sensor. If I remember correctly once I unplugged its connector, but the engine was turned off. Is this the normal range??? There is some reset procedure for this sensor?
Accent LC (2000-05) :: Stuck In 3rd Gear / Steering Wheel Shakes While Idling
I just bought this transmission from a reliable parts dealer. Should have about 50k miles on it. Looked really clean when I got it.
The guys who put in the tranny cracked a speed sensor, so I bought a new one and put that in. I dried off the sensors and screwed them into their spot on the tranny after removing the intake filter that was in the way.
Even with the new speed sensor the car is still doing the following:
1) Does not go into reverse until I've gone into drive for a couple seconds, pulling forward. Reverse does not work. However, when I unplug the speed sensor reverse works right away, but we still experience the following...
2) car goes from first to second gear to third gear smoothly, as it should. Seems really smooth like a car should shift! However... it won't go past 3rd gear and then it won't downshift! So, even after stopping and idling, I can't leave 3rd gear.
3) When I turn the car off, then turn it right back on, I can go through first, second, third gear again then... it stays in 3rd gear.
Another issue that has come to my attention since I got the car back, is the steering wheel shakes pretty hard while idling with no gas. While driving it seems smooth -- idling again it shakes heavily. what could they have damaged while putting in the tranny to cause this shaking?
So far as the funny tranny stuck in 3rd gear, it seems to me like it's a computer issue? But, what could be the cause? What tests can I do to determine the cause of this problem besides the ones I've run so far?
Accent MC (2006-11) :: Car Shakes When Accelerating And Going Uphill
2010 Hyundai Accent GLS (automatic)
Just noticed the last few days that my car has developed a shake when accelerating, but stops after a certain speed. It isn't bad yet, but when I started going up a hill today it was significantly worse. The entire car started shaking, but stop after the car leveled out.
I just put in a new front left and right axle two weeks ago, would that have caused anything ?
Accent MC (2006-11) :: Engine Shakes For Two Seconds Then Cuts Off When Reversing
My 2007 Hyundai will randomly after being parked for 3+ hours will stall (engine shakes for two seconds then cuts off) when attempting to reverse. This only happens when the car is turned on then trying to reverse. It will NOT do this when driving and later putting the vehicle into reverse. Additionally when the weather is extremely cold or hot this becomes more frequent. If the car can be shifted into reverse without stalling within 5 seconds it will NOT stall. To solve the problem I have to either keep trying to turn on the car and shifting to reverse until it doesn't stall out (sometimes 3 tries or more) or putting the car into neutral and pushing. I have to stress this only happens after having the vehicle sit for more than several hours even a day and is random. One day no matter how many times I tried turning the car on and trying to reverse and repeating it would not stop stalling out. I had to wait till the parallel parked car in front of me moved so I could get out of my spot. What is wrong with my car? I have taken it to Porter Hyundai TWICE and they cannot determine the problem even after scanning for codes.

So I just got a bunch of work done on my car: the timing belt, spark plugs, serpentine belt and water pump were just replaced. I had the oil changed, the fluids changed, new front tires, and an alignment all about a month ago, but now every time i turn my car on there is a squealing noise coming from my engine (i assume a belt). Then when i get to higher speeds the entire car shakes, but more so on the drivers side. I have also noticed my brakes just starting to squeal as well, but the shaking was occurring before that. What it might be?

Accent MC (2006-11) :: Engine Dies When Comes To A Stop?
In the last 6 weeks my 2007 Accent has died when I've come to a stop. Once in traffic on the freeway and the rest at stop signs or lights. The car will start back up and won't die again for a week maybe. Nothing consistent. I took it to a mechanic and nothing shows up on the computer. I took it to the dealer, still nothing on the computer. He cleaned the throttle body I think and put an additive in the tank. Two days later it died at a stop sign. Automatic transmission. Ok, what's the problem?

I have a 2006 Hyundai Accent that won't start. My wife was driving home the other day, and while she was sitting at the light she said she noticed a sudden change in the idle. She said the car starting shaking a little and idling really rough. When she tried to accelerate after the light changed, she said the car sputtered and would barely go.
She was only a couple of blocks from the house so she continued home. The car made it the rest of the way home, but she said it never went over about 5 mph even though she was pressing the accelerator as she would if she were going about 30...the car just never responded. When she pulled into the garage the car died as she was turning. Now it will crank but it won't start at all.
I tested the crankshaft position sensor with my multimeter and it was bad. I bought a new one and put it on, and I tested it immediately. The new one works, so I plugged everything back in and tried to start the car...nothing, just cranks and won't start. It's getting fuel and fire as well (tested both), but it's not hitting on any of the cylinders.
Accent MC (2006-11) :: Hiccup While Idling And Also When First Hitting The Gas
About 2 months ago my 2008 accent 3 dr hatchback started to do what i can only explain as a hiccup while idling and also when first hitting the gas. But I didn't have. Check engine light on. So I changed the air filter and put techron a fuel injector cleaner in it stopped until last night so I am replacing the spark plugs. Is there any thing else i should look in to replacing?

I bought a 2009 Hyundai Accent used at 110.000Km. I've only been driving it for 3 weeks and today I went to start the car and it turned over and died right away. It did this a couple of times then it finally started fine and I was able to drive it. What it could be?

My 2010 Accent has been stalling intermittently, always when I am idling. I'll be at a stop light, and it will stall, and then it usually starts right up again. It is almost always the same stop light on my way to work, like clockwork, and likewise on my way home from work. Also, sometimes right after this stalling event, the motor will be a little rough on the highway, sputtering like it's not getting gas very well, but then it evens out after a while.
Yesterday for the first time it died and wouldn't start again. I suspected my fuel pump had gone out. I had it towed to a repair shop, but it started just fine for them and they can't re-create the problem. It doesn't give any computer codes at all.
Accent MC (2006-11) :: Stall Out While Idling Or Even Rolling In Neutral
I have a 2010 Accent GS, 5 speed. While sitting at a red light, or even rolling in neutral, the car will just die out. 90% of the time, the car will start right back up, no problem. A few times, though, it would not start right back up.. I put my flashers on, and just keep trying. It eventually starts up again, as people honk and get angry at me, but once a nice guy pulled over and offered to give me a jump and it started right up. I drove right to an autoparts store and had them test my battery, starter and alternator. All came back perfectly fine. There is no check engine light coming on when this happens. There is no code produced. A knowledgeable friend recommended i just change the battery since my car is 6yrs old, 104k miles. He said he had a similar experience and just changing out the battery solved everything. Well, i just did that and it stalled again. That obviously was not the problem.
View 8 RepliesAccent MC (2006-11) :: Code P0339 - Car Stalling While Idling
Twice today my car stalled out while idling. Once at a left turn red light and once in the drive thru. The first time it restarted after about 10 minutes. The second time it restarted after about 2 minutes.
Car is throwing cod P0339 for Crankshaft Position Sensor A Circuit Intermittent.
I did some reading up on this on the forums but didn't do much about it. I just tried wiggling the wiring and all that when idling, didn't notice any roughness or stalling so.... may not be a connector issue.
Anyhow, planning to take it in for diagnosis and repair as it's really not derivable the way it is.
Actually this is the first time ever the car has given me engine trouble of any kind. just passed 90,000 miles. Shucks, streak broken.
Accent MC (2006-11) :: 2007 SE - Horn Sounds As Car Starts Then Dies
Got a weird issue with my Hyundai Accent 2007 SE. Used my key fob to open the driver's door, no problem. Tried to start the car and the horn went beep-beep-beep in synch with the motor trying to start and then on the second attempt to start it, the engine would not turn over at all, nothing--just dead. A little while later my wife said she heard the car randomly going off, no pattern just beeping. She said she hit a couple of buttons on her fob and it stopped. I let the car sit for about an hour and then went out, unlocked the car driver's door with the key (not the fob), tried to start the car and there was no issue...it turned right over. What is going on?
View 2 RepliesAccent MC (2006-11) :: 2009 - Idling Rough / Cylinder 2 To 4 Misfire
So recently my 2009 hyundai accent has been idling rough, and has been very sluggish when accelerating. Usually the rough idling is the worst when the car is first turned on and tends to tone down as the car keeps running. I had the codes red and I believe it was C0302 C0303 C0304, saying that cylinders 2-4 were misfiring.
I replaced the spark plugs which didn't fix the problem, although cylinder 4 did have a small amount of oil above the spark plug and a little bit more below the spark plug, I am not sure if that means anything useful or not. I don't have a way to check the coils directly but I swapped coil 2 with coil 1 and checked the codes again and it was still cylinders 2-4 misfiring, so I would imagine that means the coil isn't the problem. I then tried spraying WD-40 around the vacuum tubes, and if the intake manifold is on the back of the engine I tried spraying it around that gasket as well, but I didn't notice a change in the idle speed.
At this point I am not entirely sure how to proceed, from what I have read the issue causing a misfire would be either there isn't a spark, which seems unlikely at this point, or the mixture of fuel to air is wrong. That is the part I am unsure of how to diagnose/

View 4 RepliesAccent MC (2006-11) :: Stalls When Idling - No Check Engine Light
So, I have a 2011 Hyundai Accent. It drives great. Until recently.
My wife noticed that it was cranking a little longer than usual before starting. Then, one day, I noticed it. So, I stopped the car and restarted it to see if it would happen again, and listen more closely. But, all ti did was crank.
I became upset and went in to do some research and make some phone calls. I came back out and voila, it magically worked fine again. Weird, I thought.
A few days later, no incidents. We go to the grocery store. On our way out, it cranks longer. This time I'm not going to restart it, I think. So, I start driving and everything is great. Except...it suddenly wasn't accelerating. It felt like it was in neutral for like 100 feet or so, then back to normal. We're making plans to take it into the shop at this point.
The next day, we go out to get coffee. Car drives great. On our way out, no problems. We stop at the red light, and it stalls. I have to push it into a parking lot and call the tow. Strangely enough, it starts again ten minutes later, and runs fine.
The stalling and being unable to start for tenish minutes phenomenon has happened three times.
We took it to the shop, it actually did this as I was filling up gas--stalled. I pushed it into a space and waited a few minutes, bam, it started up fine. The mechanic told me that the engine light had been reset. He couldn't figure it out. Said everything looked great.
So, the run down is this:
-My car stalls when idling, but only after it has been driven some, stopped, and restarted without a lot of time passing--like when you're coming home from the store or something, after it sits for 30 or 40 minutes.
-Once stalled, it will not restart again until a few minutes have passed --something like five to ten minutes.
-There is no check engine light. Fluid levels are good. Connections and whatnot, according to the mechanic, looked good.
-When it stalls, all the electronics stay on and work. The oil light and engine light pop up (like this key is in and turned part way), then it all goes away when the car restarts.
-the computer says that it was reset after it does this.
Accent MC (2006-11) :: When Stopped At Red Light Car Just Turned Off
So, yesterday, when I stopped at red light, my car just turned off. I tried to turn it on, but I couldn't. I kept trying, and after 30th try it turned on. I had this same problem month ago, but it disappeared until now. I can turn it on by pushing when it happens. Is it fuel pump? Or some sensor?
View 12 RepliesAccent MC (2006-11) :: Rebuilding A Motor Where The Timing Belt Broke While Idling
In the process of rebuilding a 2007 Accent where the timing belt broke while idling.
Pulled the head, ran a "water test" on the valves (put spark plug in, pour water on the valves and see if it comes out the exhaust/intake side) and found that only 2 intake valves were belt. Also shut off all the lights in a pitch black room, shined a flashlight in the intake/exhaust and didn't see any light leak from any of the cylinders except the one with the 2 bent valves.
Does this make sense? I would assume since 2 cylinders are always TDC at once, at least 4 valves would be bent.
Lastly, before rebuild I'll be replacing the 2 intake valves, all the valve stem seals, intake manifold gasket, exhaust manifold gasket, head gasket, head bolts and valve cover gasket. Anything else I should replace on the head? Trying to keep costs down as much as possible.
To add: Pistons have no damage on them, there are no marks of the valves hitting the pistons. The timing belt was replaced after it broke and the engine still ran however it ran rough. Compression test was done on only cylinder 1&2, 1 had 60 PSI and 2 had 0 PSI. Compression test was also done by just rotating the crank with a socket since I already had some of the engine disassembled.
Accent MC (2006-11) :: Engine Was Idling / Little Rough And P0302 Code Thrown
So I bought my accent used a couple months ago. It is a 2007 SE 3dr 5spd manual. It ran nice during my test drive and the price was right so I bought it.
Now I'm wondering if there is any way to find out the service history on the car...at least the major one's (30k, 60k)?
I ask because recently the engine was idling a little rough and it threw a P0302 code so I changed the spark plugs and holy-cruddy-deposits-batman those things were black. Gapped the new ones and popped them in and its a noticeable difference. My CEL keeps coming on and throwing a P0496 code as well, virtually once every tank of gas. Its not the gas cap so my next step there is to check the PCSV and hoses.
With these little problems, it makes me wonder about any larger issues. I know the timing belt on these things is supposed to be replaced at 60k. Additionally I would be willing to bet that my ECM software is out of date. Would Hyundai have records for any of the big maintenance milestones since they are required for warranty work?
How much does it cost to have a dealer check your ECM software and update it if needed?
