CarComplaints.com Notes: There's an emerging trend of transmission problem with the 2010 Elantra at fairly early mileage.

So far owners report having the transmission replaced under warranty but that won't hold up for much longer. It may be a bit premature but for now we're putting the "CLUNKER" rating on the 2010 Elantra just to be safe.

Speaking of being safe, you might not be unless Hyundai can figure out why their airbags aren't deploying.

  • 64,000 miles


I was surprised to need to have my transmission completely replaced after only five years. It seems like the transmission slipping has been a recurring problem with this make model and year. Even the dealership mentioned that the reason they had my part in stock because they'd been doing lots of transmission replacements.

Elantra GLS 2.0L

  • Automatic transmission
  • 88,000 miles

I would drive the car like normal, would shift a bit rough when I first got going but I wouldn't say problematic. Then I would go and park. If I parked for like 10 minutes, then go to drive again, it would shift to 2nd fine, but then would get to third, surge the engine and slam into 3rd (literally would throw you and make a thump sound) and then it would smoothly shift to 4th. I had issues with reverse engaging slowly and slow downshifting from 2-1.

Went to Hyundai and they said there was an internal failure at 3rd gear. The mechanic told me that there is a bulletin out for it (can't find it - different story for different day). SO...I got the transmission replaced under warranty. Now, 20,000 miles and 1 year later...the new transmission is slowly starting to have the same problem. Difference here, I am no longer under warranty, so I am going to have to go to the dealership and blow a head gasket.

I'll be damned if I have to put another transmission in this car. It's insane. It's a shame, I like the car, but this is just too much for me.

Hi all, I'm a car mechanic. I started to buy and sell cars for extra income. When I bought this 2010 Elantra at the auction I wasn't too unhappy finding out that it needs a transmission, because I know how to fixed it. It was hesitating to shift from second to third. I bought a used transmission at a junkyard comes with 3 months warranty and I swapped it and it's still doing the same thing. I called the junkyard and asked for and another one. Guess what, still doing the same thing. I get the third one and it's bad too(I really hated all those times and effort for nothing) now I decided to sell it back at the auction to get rid my head ache lol

This is the second time my transmission needs to be replaced. The first was at 56,000 miles (in a seperate complaint) and again now. They should be looking into a recall for this!

It is ridiculous that a transmission would have to be replaced this soon. After researching, I have found that this seems to be a problem with this year/model car.

Elantra ES 2.0L I4

  • Automatic transmission
  • 68,121 miles

Low mileage Elantra w/68,000 miles. Had the car since 50,000 miles (2012) bought from used car lot w/100point inspection & car fax too. Few months ago the trans started to shudder on shifting to drive, checked fluid & was nice pink, not burned & level. Well it has kept doing that a few times a week, and lately it takes about 5 seconds or more to engage reverse. Also it seems to be shifting hard into 2nd or 3rd & also revs like if it dropped into neutral.

Well as of yesterday 8/21/14 we were cutting thru a neighborhood doing about 15-20mpg & the whole car shuddered(like a dup, dup, dup, dup) like it skipped gears 4 times & the engine jerked & shut off. I restarted it & it idles funny & when I put it into drive or reverse it shuts off & make a pressure type sound(like a purging of air), I noticed that when the hood was up & my wife started the car then it died upon shifting to drive. I checked the trans & oil & all fluids are fine & level-no burning either. I don't believe that I'm covered at all for any dealer warranty-I am the 2nd owner & I heard the 10yr/100k only applies to the original owner-which was Enterprise Rent-Car!!! Haven't got it checked out yet, gonna have to pay someone $100 or more just for a diagnostic, I just can't wait!!! So for now it sits & I'll pull out my old 97 Chevy Lumina for a daily driver.

Elantra GLS 2.0L V4

  • Automatic transmission
  • 71,000 miles


Was really disappointed that my 2010 Elantra had a failing transmission. Started having issues probably at about 70k or so. Started slipping a lot and jerking a lot when shifting. It even had a few times at the end where it wouldn't be in gear at all. I had it checked out and they said, yep, your transmission is failing, and I'm like you're kidding me, at 71k miles!? On a Hyundai!?

I'm so glad I purchased the extended warranty when I bought this used because they replaced it. I got a brand new transmission at 71k miles with only my $100 deductible. The bill said it would have cost me $2400 in parts and labor otherwise, whew! But still this car should not be having transmission problems until upwards of 200k miles which is really disappointing about Hyundai. I'm hoping this is the last of the big issues and that this will mean I will be able to push this thing even longer because of having a new tranny put in.

  • Automatic transmission
  • 20,000 miles

I had to have the transmission replaced on my car at barely 20,000 miles. I bought the car new, and drive less than 6000 miles a year on average. I'm old, I listened to my husband talk about and fix every vehicle we had for 37 years, in addition to listening to my oldest son talk about vehicle mechanics for 30 years.

When the transmission started slipping, I knew that's what it was and called the dealer. They were sure it was just a minor thing - no biggie. Bring the car in - it's winter - could be the weather, etc.. Took the car in and talked to the supervisor in the shop. What did I know? It's probably something minor. I left the car. Two hours later he calls and says "uh, we have a little problem. We're going to need the car for a day or two to fix the problem, but first we need to order the part". uh huh...what part???? Uh.... the transmission! No kidding!!! I did NOT say "I told you so!"

I should have known better than to buy a Hyundai. My sister bought one years ago when they first came out, and had to replace the transmission at about 3,000 miles!

  • Automatic transmission
  • 54,500 miles

Okay, so I purchased a used 2010 Elantra May of 2013. I've had it barely over a year. While driving the car on the highway, the car starts to jerk like it wasn't in the right shift. We parked for maybe 5 minutes at a restaurant. When I started it up to leave, I put the car in reverse but nothing happened. I took it to a mechanic and he said it was the transmission and that I may need a new one. The car is under 5 years with 55,400 miles on it. It just makes the standard warranty. I am scheduled to take it to the dealership next Wednesday. Hopefully it can get taken care of.

  • Automatic transmission
  • 37,282 miles


Automatic transmission stutters every time on the upshift from 1st to 2nd gear (at about 20 km/h) and then again from 2nd to 3rd gear (at about 40 km/h). Occasionally slips into neutral on the downshift. Started at around the 60,000 km range. A real pain in the butt and also not getting near the fuel efficiency advertised, not sure if this may be the reason.

Elantra GLS 2.0L

  • Automatic transmission
  • 51,400 miles

Took my Elantra into dealership for problems with a hard shift between 2nd and 3rd gear. After diagnosis they tried telling me to change the fluid (and they claimed Hyundai says every 30K, which is a lie) and see if that helps. I point out the lies they tell and after "checking" further, I am informed they are ordering me a new transmission for an internal component they can't fix. How confident am I that the new one won't fail in another 40-50K miles??? NOT VERY!

Update from Aug 1, 2014: Took my Elantra into dealership for problems with a hard shift between 2nd and 3rd gear. After diagnosis they tried telling me to change the fluid (and they claimed Hyundai says every 30K, which is a lie) and see if that helps. I point out the lies they tell and after "checking" further, I am informed they are ordering me a new transmission for an internal component they can't fix. This issue is bad enough that a car with 51,000 miles needs a new transmission, but than the dealership I dealt with trying to lie and get out of warranty work. So now I wait until the new one comes in...meanwhile the transmission seems to have worsened since in their hands. Intend to find out about getting a loaner sooner than when the new tranny comes in. What an annoying pain to have to put up with. How confident am I that the new one won't fail in another 40-50K miles??? NOT VERY! This experience (and previous with this dealership) has led us to not be in the market for another Hyundai when the time comes to purchase another vehicle. When you buy a car with a warranty and do the maintenance spelled out in the manual, and something goes wrong, that shouldn't, you expect no issues with the warranty.

Oct 012013


  • Automatic transmission
  • 62,000 miles

When driving at highway speeds, the transmission slips out of gear and the RPMs go sky high and the car runs like it is in neutral. I have to tap the brake before it will adjust and go back into gear. This seems to be a bigger problem when carrying passengers. The added weight appears to be a factor. It's rather dangerous since it can happen at any time without notice and happened just this past weekend when driving in MPLS in heavy traffic.

I first registered this problem in the back of my mind at least a year ago, but not knowing a lot about cars, I didn't think to report it. The car is just beyond the warranty stage and I am hoping there is something the dealer can do to help me out. I love this car and am devastated to be experiencing such a serious problem.

Elantra GLS 2.0L 4 cyl

  • Automatic transmission
  • 52,000 miles

My 2010 Hyundai Elantra GLS needed to have the transmission replaced at 52,000 Mi. I noticed it had issues shifting from 2nd to 3rd gear (it would either drag into gear, or slam into gear)

Dealer fixed it under warranty in three days and provided me with a rental car. Still, I am a bit concerned for the long term health of the car. I had hoped to keep the car for 10 years...we'll see.

Dec 162013


  • Automatic transmission
  • 44,000 miles

I bought this car on Sunday, did the standard drive around the block test drive. But as soon as I got if off the lot (Dealer) felt a shudder when decelerating from over 40 MPH. Definitely not down shifting properly.

Took it in and was told that I need a new transmission. That was Wednesday.

Very disappointing since I bought this "Certified Pre-Owned" apparently the transmission is not on the 130+ point check list.

But it is still under the 10 yr/1000 mile warranty and is being repaired on the dealer's dime.

It takes the excitement right out of getting a new car. :/

  • Automatic transmission

I am hyundai elantra driver. Car is good except sometimes during drive, when gear changes from 2nd to 3rd, I feel a jerk like it is slipping the transmission, though I am not sure. It is not because I haven't gone for an oil change. It happens even after the oil change. Went to dealer and he didn't feel anything. Okay, it doesn't happen every time but it happens quite often. Maybe I'm wrong but I also drive a honda civic and that has smooth transmission.

You don't expect a new car with 26,000 miles to need a new transmission. So much for Hyundai's Quality reputation.
