My car has the wavy acceleration feel and sometimes hesitates a bit. It is way worse when the a/c is on. I wonder if this is a octane or sparkplug issue. On my old cruze 1.4t the gap was wrong from the factory. It came with all four gapped under .022 but the manual called for .028. Everyone gapped to .035 with great results. Not checked the sparkplugs yet?

View 3 RepliesI love my 01 Elantra great gas mileage and it just zips around with no problems. Recently had an issue where i was depressing the gas pedal but it just decelerated and never was able to get above about 20mph. I pulled over, tapped on a few parts in the engine and restarted the car... the problem went away. It has some hesitaion when I accelerate. The check engine does not come on ever not even when I start the car . . . What the problem might be ? MAF, modules, ECM.... ?
View 1 RepliesThis is the second time I notice a problem with my 2014 elantra base model. The car only has 13000kms and today the car acted with a weird behaviour. This car has a manual 6 speed transmission.
Out of the blue the car jerked like it had a problem with the transmission switching gears which is weird as this is a manual.
The second time this happened the wife was driving and she said that she was in is third gear and she pressed the clutch and the brake at the same time and she felt a small jerking feel in the clutch like it didn't engage.
The problem is that I cant reproduce the problem. The car is still under warranty and I don't want to go to the dealer with a problem that I cant exhibit.
My car gives off a pulsating vibration when I'm stopped (at a light, or in my driveway, for example). Its as if someone with huge bass is sitting next to me, but I'm alone. Its a weird "jerking" feel where I can feel my seat shake like a mini earthquake.
I've tried researching "rough idle" but don't fully understand it. Rough idle implies a clogged intake, which kind of makes sense I guess. I have something better than "my car kinda vibrates when I'm stopped".
Its a 2012 Elantra Limited, all stock everything, 53981 miles.
I have been getting this weird bumpy feeling when making left hand turns and even sometimes when going strait on the road. It does not seem to effect the breaking for acceleration of the car. This does not happen all the time and will start and stop without any change in driving.
View 22 RepliesI bought a 2010 prius 3 weeks ago and a squeaking sound came out after driving it for a week. The sound is like a wooden bed not screwed tight being shaken. My prius has 40000 miles on it and the warranty has expired already. I brought it to a toyota dealership and they could not find where the noise is coming from. I decided to bring it back to the dealership I bought it from and they also could not determine where its coming from. They said they need more time to find it. The squeaks often comes out in wavy roads and bumps and in both low and high speeds.
View 11 RepliesI have noticed that the throttle is a bit light...meaning that the resistance bringing the throttle back to idle is too soft. Two issues as a result. Unexpected..faster acceleration from a stop and my leg tires a bit in town keeping speeds in the 30-45 range. Assume there is no retro fit and/no adjustment. It's rather odd in that just about everything else on the vehicle seems well thought out and executed. I could complain about the over boosted power brakes....or the brake squeel that the dealer can't/will not fix...but the throttle is really getting on my nerves.
View 5 RepliesAfter posting about the smoke upon hard acceleration, some of you stated you had the motor checked for "low compression". So, my question is what symptoms was the car having for you to take it in for this diagnostic test?
View 3 RepliesI have a fleeting issue that of course only happens on rare occasions. I have a 2011 Elantra Limited. I drive it pretty easy. On three different occasions, when I really had to get on it to get into traffic, I have left a huge plume of smoke. From what I can tell it's darker in color, but it's been usually evening so I can't really tell. If I punch it again, it's fine. I have mentioned to the dealer each time and they say nothing shows amiss.
View 229 RepliesFor the last few weeks (about a month) I have been experiencing a clunking noise/ knock on acceleration coming from either in front of my feet or below my feet (drivers side) ONLY on acceleration and only then from a full stop. I can also feel the clunk as well which leads me to believe it is a transmission mount.....maybe an engine mount. I am taking her to the dealer after work today. we had some very cold weather and I was hoping it was just ice but yesterday and today were well above zero and it is still there and it is EVERY time I accelerate. Which is a somewhat good thing since I will be able to replicate the problem for Hyundai.....
View 17 RepliesI am starting to have an issue with my 2012 auto transmission Elantra that just passed 100k miles. When under mild acceleration, as when gently leaving a red light accelerating to 45 mph, I can feel a distinct chugging as if a cylinder is randomly mis-firing once or twice a second. This is never felt during coasting with no power applied. It is also not apparent during full throttle or aggressive acceleration. Only during casual daily-type driving. Now I have had other cars in the past that once in a while would throw a CEL code if a cylinder mis-fired, but I have no Check Engine Light on. This leads me to doubt a mis-firing plug. What could be the cause of this?
Other possibilities would be perhaps the auto transmission is somehow momentarily interrupting power to cause the mis-firing effect??? Is that possible? Perhaps the fuel pump is going bad and getting intermittent? But then why is all good during full throttle?
My Hyundai Avante (2011 model 1.6) suddenly loses acceleration while my foot is still pressing on the gas pedal. Every time that happens I have to raise my foot from the gas pedal and press it again to make the car accelerate. This thing happens randomly, but mostly at speed lower than 80 Km/h
I tested the car on an empty road once; I didn't raise my foot from the gas pedal this time when the car lost acceleration. The car speed dropped to zero and the RPM gauge returned to idle (i.e. around 1000 RPM).
The check engine never light up during or even after this thing occurs. Here is the list of things the mechanic tried on my car:
1-Cleaned the body throttle
2- Tested the car with another used body throttle
2- Tested the car with another used gas pedal
3-Check the fuel pressure and injection
4- Checked the sparks
5- Tested the car onboard computer.
None of the above worked!!! Here is the strange thing my mechanic discovered, if he unplugs the cable of the Anti-lock braking system in the car. The problem never occurs.
I have been driving the car for two weeks, with the ABS system unplugged. The loss of acceleration problem never happens. I am not sure what the ABS has got to do with the car acceleration.
My parents own a 2013 Elantra 4-door (sedan) and for the last few months it's been making a metal grind/squeak. Here are the following characteristics:
-It occurs only during acceleration from a full stop or low speed. It would then disappear if we drive it longer or get to 60km/h.
-We've diagnosed it to the front right wheel.
-It sounds like the squeak at you get when your break pads are almost used up - metal on metal grinding squeak
-It seems to be temperature related as the squeaking occurs less during cooler temperatures - it comes back once (I assume) the wheel / brake / rotors are sufficiently warm.
We have brought it to a mechanic and he did hear the squeak. He took of the pads and re-lubed (not on the braking side obviously). No change. BTW the pads are still very beefy and is the original pads that came with the car.
Searching online it seems this issue is fairly common and it seems to be the brake pads. Is this what's happening to my parents' car? If so is it as simple as replacing the brake pads with a different brand?
So, I have a 2016 Elantra SE Auto w/ 26k miles, I have 1k miles life until my next oil change.
Since about Saturday, whenever I accelerate, around 3k RPM - 4k RPM it's running/ sounding really rough! Not sure what's causing that, I checked my air filter earlier that day & put it right back in, also put in some HID lights in. I thought maybe the containment cover or gasket around the filter wasn't seeded properly, but everything checks out. I'm pretty car savy, so I know this isn't normal for brand new cars. Doesn't seem like it's loosing power, I still get pretty quick throttle response when I really gas it!
I just bought an 05 Camry with 40k miles. Runs great. Decided I'd have a tranny flush and coolant flush done. Oil was done recently. A couple hundred miles later and today I've got a noticeable hesitation when accelerating. It's not a herky jerky stutter, but a smooth, consistent like a loss of power like I'm quickly letting my foot off and back on the accelerator. Doesn't seem to do it when not in gear, just under acceleration. Checked trsnny fluid and it's ok and full.
View 9 RepliesEvery time I reach about 64 mph, the car begins to sputter spontaneously. As I give constant gas to keep it at that speed, the car hesitates, as if the gas isn't combusting consistently. This sputter also happens sometimes when I'm simply accelerating for example from a stop sign, however, it is CONSISTENTLY doing it at about 64 mph. I can go faster and the sputtering seems to lessen (at 70+mph, as long as I'm accelerating). Took to mechanic, he couldn't figure it out, although they suggest getting yet another computer.I've replaced:Distributor capDistributorSpark plugsComputer (from ebay, remanufactured)
View 13 Replies2013 Elantra manual. 60,xxxkm, owned from new, purchased in August 2013. Oil changes always done within 5-7000km. Was 2000km over my oil change due date when this happened (haven't had time to get it done, been driving my motorcycle mostly). Driving around today I dropped my wife off, then I heard a quiet ticking noise under very light acceleration.
The noise would go away under normal acceleration, no noise while revving, and no noise while engine braking. The noise got worse after about 5km. I was in traffic and engaged the clutch into first gear, the car stalled violently. Turning the key results in a click, then nothing. In 1st gear the car will not roll forward. In reverse the car will not roll back. It still rolls in neutral. Had it towed to my local Hyundai dealer and got a rental. Waiting on the results.
Never saw a drop of oil on the ground while parked, and never smelt any oil burning. I run between 87 and 91 octane, whichever is available. I have the extended 160,000km 8yr warranty, hopefully this is covered as I still owe about 15g's on the car.
I have a 97 Pontiac Grand Am w 3.1 engine that is my son's college car. We recently rebuilt the original engine and put it in after having a 99 monte carlo 3.1 engine in it's place and it had a head gasket problem as well. Just before we switched engines my son was noticing that it would kind of hesitate under acceleration from about 1500 rpm to around 2000 rpm especially when it was wanting to up shift. I figured it would resolve itself with the engine change. It did not. It has now gradually gotten worse.
My son drove it to Liberal about 4 hours away and he stated it was worse and especially when you would get into overdrive it would drop down to around 2000 rpm then start sputtering or loading up or just being dead then would down shift to 3rd and try to clean itself out and speed up and then up shift to OD and do the same cycle again. I drove it back and kept it in 3rd gear and seemed to run fine at 2500 or higher. I also had to go thru low, and 2 and feather it up from a standing start. It idles fine as well.
I thought it might be like one of the saturns I had which ended up having a plugged Catalytic converter and a bad coolant temp sensor. This morning I did a test hole and it made no difference. I tried a different coil pack/ESC and it made no difference. I cleaned the MAF sensor and no change. The fuel pressure is 41 then 38 when idling then 43 when remove the fuel pressure regulator vacuum hose. I also changed the fuel filter.
I was kind of ruling out the tps, iac, and egr and water temp sensor as those were part of the other engine when I put the other engine in so they are different and I am assuming they must be good. Plugs and plug wires are new as well. It has not thrown any codes. I did notice that when it is just in park and you press on the accelerator to rev it up it only will rev to 3500 rpm and will shut down like a rev limiter is kicking in and just do a kind of surge thing. My saturn did that too and it was a plugged cat and when I knocked the biskit out of the manifold on that car it stopped. I have already got that ruled out though.
When driving, if I let off on the gas, my 2016 Elantra kinda coasts for a second or 2 and then does a rapid deceleration or sometimes sudden acceleration and moves unevenly instead of coming to a smooth stop or slowly coasting at a constant speed. The car jerks just enough to feel like I'm braking a bit. Not smooth like it should be.
I have been using my Elantra 2016 since end of last year. It has mostly been like this since the last few months and lately it has increased. Also, lately my fuel economy hasn't been great as well. Why my Elantra has been behaving like this?
I have only done 18,000 Kms on my 2013 Elantra GLS. Whenever I am in traffic driving real slow, and whenever the gear shifts in 2nd, the acceleration begins to drop to 1000/1500 RPM very rapidly while pressing and releasing the pedal, and it becomes jerky...
I will try posting a video, but meanwhile, it gets really annoying at times and I need to maintain a very feather foot to make sure it doesn't jerk especially when there are passengers on board..
