Elantra MD (2010-15) :: 2012 - 3 Small Backfires For About 2 Seconds After Engine Shut Off
Sep 3, 2014
This just started last night. 2012 e ltd goes "pfft" 3 times after shut off. Sounds like 3 small back fires about 2 seconds after I shut off engine. Very soft sound. The third one is not quite as loud as the first two, and if the door isn't open, you can't hear it. Seems to be coming from under the engine cover, near the throttle body.
Let me add the mileage has dropped from about 26.9 in town to 23.6.

I have a Hyundai Elantra Limited 2012. A few months ago the Short Block was replaced because the engine was noisy. Now it started to do that noise, if I remember it's a little bit similar : Youtube video: [URL] .... Or search youtube for: Hyundai elantra 2012 engine rattle noise
It rattled very loud for 1 or 2 seconds on a cold start the other day too. Noise appears to be coming from the engine. It does it pretty much all the time, at idling, when I accelerate it accelerates too and when I slow down it kinds of do too slowly. Need another new short block or is it something else like the timing chain or a bearing?

Having issues with a 2014 shutting down. Was at a stop light the other day and car completely lost power and shut down. When this happened oil, engine, and battery light came on. Once I parked car and turned off, it restarted. The dealership acted like I had no idea what I was talking about and would like to have some information when I take it back to have this problem corrected the car is not even 2 years old and has 30,000 miles on it.

I have a 2003 Elantra 2.0 with no spark, no codes... anymore. The car was driven about 6 miles, shut off, went back out to start it, it ran for 10 seconds then shut down. Now it will not restart.
What I did: As per some of the advice of others I replaced the crank sensor, cam sensor, ignition coil, check compression, pulled codes from the ecu with one being a crank sensor. I have power at the fuel pump during crank, i can smell gas during crank, plugs are dry just no spark. Timing belt and timing are fine, engine sounds as it should during crank but no spark. There is power at the coils, crank and cam sensors. MIL is on when key is turned and goes off during crank.

I'll provide as much info as possible concerning an all too common problem with these cars. The radiator (passenger side) fan will run for a few seconds when the AC is turned on, then it will shut off. It does not come on when the car is up to temperature. The AC condenser (driver's side) fan runs normally. Steps I have taken so far are as follows:
A. Replaced the radiator fan -- no joy.
B. Replaced the coolant temperature sensor -- no joy.
C. Replaced the thermostat -- no joy.
Coolant level is normal and there are no leaks in the system. The temperature gauge however, never rises above cold.
My questions are:
1. What are the next step(s) to solving the radiator fan problem?
2. Is there a separate sensor for the temp gauge, other than the one in the thermostat housing and if so, where is it located?
3. Since I live in AZ where it never gets very cold, I'd be perfectly fine with having the radiator fan run whenever the engine is running. Is there a way to wire it so it's always on with the ignition?

I just got into my 2012 GLS Elantra and tried firing it up, and the engine will turn over, but wont start. Power windows, radio, lights, everything works. Earlier in the day, I moved the car from the garage to the driveway and turned it off about 30 seconds after I turned it on..
I've read things from checking the sparks to the fuel pump..is it possible that it could be flooded? I am leaving it alone right now and I plan to try to fire it up in an hour or so with the accelerator fully pressed down in case this is the case, hopefully that does the trick..

Today noticed a knockng sound louder than the usual engine knock. It only occurs when we put car in reverse. Checked it with the brakes applied so as to eliminate it coming from any source due to the car moving ie axle/drive connections etc. Putting it in D with brakes on, not moving and it goes away. Put it back in reverse and it recurs.
Tried it even after the engine had warmed to temp guage showing half way. Let car sit for a bit (so engine was still warm) and it repeated. Drove for a few minutes and it would not occur. Shut car off for 1 hour, on restart the engine temp was showing it was still warm and the knock would recur in R.

All stock 460 in a 1987 1-ton 4x4. The carb has lost it's cookies I think. It (all of the sudden) developed this massive flat spot right after I shift gears and open the throttle. It falls on its face, then catches and slams the whole damn truck.
Also pop-pop-pops really badly when I downshift and occasionally backfires when I shut it off. I'm (barely) smart enough to know that it's getting excess fuel dumped through the engine. I just pulled out both float adjusters, cleaned them, and reset float levels and it made no difference whatsoever.
It's my only vehicle and it's barely drivable.

Our 12 elantra with 26,500 miles went up in a big cloud of smoke on monday. Driving along about 45 miles an hour and lost power and huge cloud of smoke. Engine still running but any attempt to accelerate and it falls on it's face. Smoke out the taipipe all the time. After about 12 dealer excuses they say it needs a new short block. The wife drives it all the time so it doesn't get babied and it doesn't get the snot run out of it either.

I got a small rust spot on a corner of the hood of my car (5 months old). The 3 year/36,000 mile paint warranty included with the purchase of the Elantra should take care of this, correct? It's small so I was gonna sand it down myself and use a touch-up pen, but now having second thoughts. Should I take it to the dealership instead?

There is a small clunk in the front end and I think it could be the hood. When I press on it with my hand I get a small clunk. I have had the dealership look at it and they are not sure of any way to adjust it. Most cars have rubber topped screws to adjust the hood for a tight fit, but the elantra does not have it.

So I have a 2012 Elantra Limited. From what I understand the power steering is no hydraulics and is only electric assist. So I have a strange problem. I can remember in previous cars when a power steering pump was going bad it made a whining type noise that changed with engine speed. My Elantra is making the same type of noise. I'm trying to track this down. My car doesn't have any other symptoms aside from the noise. It's hard to really tell but it does appear to be coming from the belt side of the motor (passenger side).

I recently bought a 2006 Jetta with 31,000 from a used imported cars salesman. I've had it for 5 or 6 months and have put on 4,000 miles since I've gotten it. Sometimes it won't start for 2 or 3 days, it wil rumble the engine for 5 to 10 seconds then shut off. Then it will randomly start working fine for a day or two, and repeat itself.

Every time I turn my car off, I can hear a small puff of air releasing from around the engine (front grill area) if I am in front of the car (not loud but you can hear it when you are in front of the car). I have a 2013 limited USA version.
Also, how do I remove the negative battery terminal? I would like to do some lighting work and I want to stay safe doing it.

For me it happens after I have driven the car for a while (engine is up to temp). I will turn the car off to go into a store or something. Then when I drive off again the revs will hang for several seconds. When this happens without my noticing it obviously makes for a violent shift into second gear. Once it does it 1 occasional rev hang car behaves normally. I know the revs drop slower when the engine is cold, but this is something totally different.

I have a 2013 elantra with about 26,000 miles on it. I usually don't use it on weekends and on Monday's it makes a noise that lasts about 3 seconds. I believe the noise comes from a pulley that is not turning.
When this first happened, pulley had a couple of lines where paint peeled off and now the pulley has almost no black paint left. Took the car to dealer, explained how the noise only happens after not using the car for a couple of days, and they have not been able to repeat the problem, they indicate that they can't replace the pulley for this reason and that the wear on the pulley is normal.
What is causing the issue?

I have a 2012 elantra limited with navigation package. My iPhone 4 will only connect and stream pandora for exactly 15 seconds then it will stop streaming to the car. The phone is not plugged in and I am just trying to get the Bluetooth to work properly. It connects and disconnects constantly. I have reset my phone but it will only stream for that short period of time. Is there a setting I need to do?

I have just bought a 2013 Elantra GLS and occasionally the passenger door won't shut. When you close the door, it will bounce back. It's like it's not catching. I took it to the dealer and they lubed the mechanism that catches, but it did it again. And of course, this is one of those things that won't repeat itself at the dealership.

The EMS service in the county next to ours lost one of it's new trucks for a few days on Tuesday. While going on a call, the engine made a tapping sound for only a few seconds, then a loud pop and shut off. Ford dealer went and picked it up and took it in for evaluation. VERDICT: Broken rod and cracked block. I have to say, this is the first I've heard of a 6.7L having a problem like this in our area.
Ford was really interested in this engine, as a new one is already on the way and the old one is to be shipped back for complete breakdown. So far, the Director and County Manager have been impressed with Ford's response to this problem. Dealer has told them the truck should be ready by the middle to end of next week. If I hear anything else, I will let you know. Any engine can break at any time, I'm just glad they are moving quickly to rectify the situation.

I have a 2012 GLS automatic with 78,000 miles on it. Till now I never had any issues but recently I started having issues with starting the car. Its taking few tried to get it started. This happened 3 times and I got it checked at 2 places and they said everything (battery, starter, alternator) looks OK and they may not be able to find the issue until car breaks down as issue looks intermittent.
Later one time, I was driving on local road and car kept moving but I felt a small jerk like engine is stopping or gear shifting...and RPM fell to 0 but car kept moving. I stopped on the shoulder and turned off the ignition. After few trials, car started again and moved fine. This same issue happened today morning on the fwy when I am driving at 70 mph. It started after few trials.
