Hyundai - Elantra :: Slow Acceleration / Car Takes Forever To Speed Up
Jul 7, 2016
I came off the turnpike the other day stopped at a light and my car, 2006 Hyundai Elantra 175000 miles, started rolling backwards. I put my foot on the gas and there was no movement. Put the car and park and it wouldn't start. I pushed it into a gas station and the attendant (attendant, not mechanic there was no service station) changed the oil and added some coolant. The car then started up fine and I was able to drive a quarter mile to work. When I was driving home I immediately noticed that there was a change in acceleration. It takes forever for the car to speed up... Pedal to the floor and it is lagging greatly. It seems to be going up to 4500 rpms just to reach 40 mphs at a slow pace. Once the car gets up to 60 mph the rpms drop to normal. I haven't gone faster than 60 mph in it since this happened, but it seems to handle fine at that speed. The issue is getting up to that speed. I don't know if it is related, but the air conditioning is very weak since all this happened. I have to turn it off when I'm accelerating now. I've been planning on buying a new car soon, but I want this one to last just a little while longer.

I drive an '04 Passat and I've recently noticed that my AC is not functioning properly. It takes forever to get somewhat cold and the air flow seems diminished. I used to get freezing cold within minutes after setting it to an air flow of "1" and putting it at the coldest setting. Now, I can drive home and sweat for the whole 30 minute trip with it set to an air flow setting of "4" at the coldest setting. It's not as bad in the morning because it's much cooler, but it's killing me in the afternoon/evening.

I bought a new Honda Accord v6. I drove it off the lot with 40 miles on it. The acceleration was fine when I bought it.
It now has over 500 miles on it, and the acceleration is terrible. When I'm at a stop light and the light turns green, it takes forever to get to 40mph unless I floor it. Honda Civics pass me at every light.
What could be the problem? I'm very concerned.

I just got this new truck with work and when I started in the mornings and let it run for 10 to 15 minutes like I used to with the 6.2 f250 I had it's still cold in the truck. Need making this thing warm up faster?

I have a 98 GS4 and a 04 RX330 and one major issue I have with the RX, is the poor downshift response when slowing down, to say 5-10 mph and give it gas, the transmission takes FOREVER to realize I want first gear. If I am giving it 50% throttle at 5-10 mph after slowing and needing to get a move on, the throttle seems like it is there, but the transmission takes an eternity to realize "oh, you want first? hang on while I think about it", then it grabs first and LURCHES forward, giving everyone a very uncomfortable jerk.
My GS however, when down to those speeds is always spot on the right gear. Yeah, I know its comparing a GS to a RX, but wouldn't you think that Lexus would figure that one out?
Is the 04 worse than 05 or 06? Can I use an 05 or 06 trans controller and get some improved transmission response?
You can tell by the lurch, the throttle is responding to the driver's throttle pedal input, but the transmission isn't figuring it out till way too late. I don't get the lurch like at slower speeds and higher throttle input, but it sure makes for a poorly driving car.
I see the same problem when taking slower corners, get it down to 10-20 mph for a corner and the transmission won't downshift till AFTER the apex of the corner, despite what throttle pedal is pressed.

Recently my brakes were feeling a little spongy so I took my X to a local shop who installed new front and rear brake pads and flushed the brake fluid. The brakes seemed to operate properly.
But, then while driving on the interstate in Tampa, I had to SLAM on the brakes but it seemed like it took forever to slow down. It's hard to describe, but it's like when you are moving at interstate speeds and then you have to SLAM on the brakes, the X just slows down and comes to an eventual stop. It does not stop quickly.
I do not feel any pulsing from the antilock braking system so I don't think it is being activated for some reason. This seems to only happen at faster speeds. I have no problem when driving around town and slowing down for stop signs or red lights. It slows and stops just fine.
So I took the X back to the shop and they replaced the Booster w Ford booster. I thought I checked it out as soon as I picked it up around town AND on the interstate.
But, today I had to SLAM on the brakes while on the interstate again and it is acting just like before - just slowing down, but not fast and without the antilock brakes activating (apparently).

I've had my 2013 Prius since new. Basically it feels like my car is over-exhausting itself. When I go to take off, the car jerks like I slammed my pedal to the floor. If I'm on the highway and need to speed up, it sounds like it's reving really high and really long, and when I take my foot off the gas, there's about a 5 second delay before the car actually starts to decelerate. I don't even feel comfortable on the highway when it's acting up because my car kinda just accelerates suddenly and then takes forever to stop even when my foot isn't on the gas anymore.
This problem happened last summer, and when I took it to the dealership it stopped before I could show them. It started getting cold outside not long after so this didn't happen again. Now that it's hot out, my car is doing it again. And it's fine as long as the sun has gone down for the night. I thought it was because my a/c was on, but I can turn it off and it doesn't make a difference on the way the car is driving. I get regular maintenance done, all my filters are clean, and there's nothing I can really think could be wrong.

I have a 2006 Hyundai Sonata that squeaks when I turn left while in motion. It squeaks regardless of the degree of the turn but is more noticeable at slower speeds. The squeak isn't a screech so I don't think it's a belt. it isn't a grinding noise either. More like a "squeak, squeak, squeak." Seems to squeak with the rotation of the tire.

So the first issue is, if the vehicle is cold (regardless of temp outside) it takes forever to start it. It cranks and cranks and cranks and after a couple seconds of cranking I stop, wait a second, then try again. Usually it takes two sometimes three tries to start it. The guy who I bought it off of said it has newer glow plugs (last year I believe) and also I have replaced the batteries. Once its warmed up it does not do this at all.
Secondly and also something that just recently started happening, my water in fuel light keeps kicking in. I drained the water out of the water catcher reservoir under the truck multiple times and the first time water actually came out but every time after that simply diesel fuel comes out. I added a bottle of water remover to the fuel as well and ran it down to a quarter tank. Then filled the truck up completely, added two more bottles of water remover. The light still comes on. I noticed it only comes on when I am going up or down a fill. When I am driving on flat ground it does not kick on.

Occasionally, randomly, and unpredictably when accelerating from a slow speed coast I get no power response when I press down on the accelerator. It's as if the engine has stalled, but it has not. When the accelerator is held down for a few seconds (maybe 3 to 7) power comes back with a rush. Examples:
1. Making a U turn from a left turn late. Accelerate slowly forward, take foot off gas as the turn is initiated, press down on gas to accelerate out of the turn and get no immediate power response.
2. Making a left turn into a suicide lane. Accelerate to cross 2 traffic lanes, let off gas and coast slowly forward in the suicide lane while waiting for oncoming traffic to clear, traffic clears, press down on gas and get to response. Continue to press slowly down--no response. Hold the accelerator half or 3/4 down, power surges back after a few seconds.
3. Rolling slowly down a long left turn lane with foot off gas timing oncoming traffic, traffic clears, press down on gas to initiate the turn, no response. Let up on gas and press down again, no response, let up an press down again and car reacts normally.
Occurrences of this problem have been very random. I have spent a good deal of time in vacant parking lots trying to cause the problem to occur without any luck even though I know well the conditions under which it happens. I have left the car with the dealer but, of course, they can't observe the problem either. I have driven nearly 1000 miles without an incident and then had 2 occurrences within 4 miles of each other. I have about 5000 miles on the car and have logged 17 incidents.
Loosing power in traffic is, of course, dangerous. I was about to initiate action under California's Lemon Law when I went to England for 3 weeks in Sept. I rented an Audi A1 and to my surprise I experienced a very similar problem, but it happened much more often. An example would be entering a roundabout, letting up on the accelerator while looking at directional signs, reapplying accelerator pressure and getting no response. Unlike the Hyundai I didn't seem to lose all power, but couldn't get any acceleration. The Hyundai engine is the 4 cylinder turbo and has an electronic throttle. I don't know what the Audi had by way of mechanics. I'm at a complete loss; is there something I don't understand about electronic throttles? I don't have a clue about the source of this problem, but I know I need to get it resolved before I get rear ended.

I 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.... ?

I think my transmission died today. My car wouldn't accelerate past 40 mph and a local maintenance man said there's no reverse. I think I have seen other complaints about this with the Hyundai's. What the specific problem can be? I'm going to have to have AAA tow the car to a transmission shop. I bought my car used and it's beyond 60,000.

Girlfriend just bought a used Elantra. She told me about an issue shes been having with the car and how it feels as though its towing a trailer. I drove it for a day and noticed a few things. Vehicle has 110,000 miles
1. No CEL
2. Tranny seems to NOT be slipping (Revs climb just as slow as Speed)
3. Car feels VERY heavy at times. Especially on a start up-hill
4. No sputtering/misfires
5. Shifts up and down smooth
What I've tried so far:
1. Replaced Spark Plugs
2. Sea-Foam
3. Cleaned MAF/Checked Airfilter
4. Removed and Inspected BOTH Catalytic Converters and both seem to be intact. *plan on doing a back-pressure test as soon as I get the gauge from my buddy*
5. Checked timing marks
I put 1/4 can of seafoam in crank case and plan on letting it "run-in" for 25 miles or so. I plan on doing an oil change tonight as well as make sure the brakes are not hanging up (I should have checked this first, thinking back...but hind-sight is always 20/20 ) .

Recently, my 2003 manual honda civic accelerates very slowly, even the engine speed goes up to 4000 rpm. Usually it takes up to 1 minute to reach 60mph on high way. Is the clutch getting bad?

I took my 2011 Lariat in for first service and reported that it sometimes tries to accelerate on its own during slowdown from high speed, eg when coming off a freeway ramp, rpms go up and vehicle wants to speed up rather than slow down. (sounds like something a Toyota would do!)
Dealer says its a known problem with 5.0L and performed a supposed fix per "TSB 11-8-9, 5.0L ENGINE BRAKING PERFORMANCE DURING LOW SPEED COAST DOWN," essentially a PCM reflash.
Happened once in a parking lot...thought the floormat was stuck on the accelerator but the pedal was clear.

,I have a 2004 Hyundai Elantra (stick shift) with about 104k on it. Was running absolutely great till about a month ago when I noticed that it was beginning to accelerate quite slowly. If I pushed it and got the RPMs up really high it would still pick up, but still not great performance. Also after pushing it a little hard there was a faint burning or smoke smell. Note, once it is up to speed say 60 or 70 it has no trouble maintaining such speeds. It just takes a while getting up to them. And if I really need to step on it the RPMs sky rocket with no real immediate increase in speed.

2011 Elantra with phantom harsh shifting problem. Yesterday the Elantra began surging and nearly stalling out on acceleration after about 20-25 minutes driving. I was barely able to drive the car home; when pulling into the garage, there was a strong smell of something hot. Temperature gauge indicated normal engine temp; no icons lit on the dash indicating a problem. Surging/nearly stalling and overheating problem and is it related to other Elantra engine, trans, fuel system-related problems? I can’t find anything specific while web surfing today for some clues!

I have a 2001 Elantra gls which I bought a year ago. It had shifting problems from 2nd to 3rd gear with CEL on. I replaced the input and output speed sensors and connectors and fixed the problem to a point. It was still shifting a little hard even after a fluid change with SP111. I added 2 bottles of Lubeguard red and it has worked immensely almost to the point of no problems....except. At slow speed shifting like going into a store parking lot or on a freeway with stop and go traffic, it will shift hard from 2nd to 3rd (I think) maybe 1st to 2nd not sure. If accelerating at normal speed shifts fine. No cel and the tranny fluid is on the full mark, not overfilled. Would a wheel speed senso cause this or damaged clutch pacs maybe?.

We began to have an issue today with our 2010 Elantra. While driving, the Check Engine, Check Coolant and EPS lights all came on. The engine then would not speed up but run slow. The tachometer stopped working.
It was coming into our neighborhood, so we got it to our house. After checking around under the hood (fluid levels, etc.), all looked good. Then we noticed that the mats and carpet are wet up under the dashboard on both the driver and passenger sides. When I reached up into the dashboard over the wet areas, I feel water all along the wiring, etc.
I am guessing that water has leaked in somewhere, maybe after the rain storm last night. We have had the car two years and less than 15K miles. Why and where water would be coming in?

My wife's car is a 2006 2.0T Passat. It has been very slow to blow cool air on starting. Once you are moving at highway speeds it cools fine, but then blows hot air when you slow or come to a stop.
I have taken the car to a mechanic who purged and refilled the coolant. This did not fix the problem. Upon checking with the mechanic, we noticed that both the primary and aux. cooling fans start and stop at the same time, and only would come on when I would rev the engine up some (around 2000 rpm).
I have talked with this mechanic and one more. Both are certified master mechanics, but neither specializes in VW. They believe it may be the high pressure side switch or the compressor itself.
