Stalls problems

Top problems

Unstable revs, trembling, stalls, power loss

1998 Hyundai Elantra 10000 miles
I have a Hyundai 98 and, after some minutes of driving without any inconvenients, the car starts losing power when accelerating, revolutions become unstable and drop until the car stalls. Sometimes it even feels as if the engine were trembling. I've already changed spark plugs, candles, fuel pump and pistons, and even checked the car's cylinder head, but my problem is still there.

This happened to me and it was the IAC valve, which controls the acceleration. You can by cleaning it but, if the problem remains, you will need to change it for a new one.
Naz from United States 11 years ago
What samson is saying is true, it is the IAC vale that is failing. It is not hard to change it: you disconnect the battery, insert the valve, again the battery in its place and that's it. Hope it helps!

Yep, same issue - I had the problem start on me after the car was sitting in not too hot direct sun outside. EVERY TIME it slowed to a stop at lights, in slowntraffic etc itbstalled and needed to be started and revs kept high, which wasn't stably able to be done. So what causes this and what's the fix ?
Jugheas from Canada 10 years ago
I had the same issue and it was the alternator that needed replacing. It went undiagnosed for 3 years. Hesitation when accelerating and also a lot of blown head lights almost every 3 months I had to replace them. I thought it was the wiring to the distributor cap anD also replaced that. But the alternator did the trick. I discovered it one day when I had the car idling for 20 minutes and it died on its own. The alternator was partially functioning but under load wasn't producing enough current.

This was the case for me too on my 2006. Every time I talked to a car parts store or my mechanic about the problem, they said my battery just wasn't charged enough to get a good read on the alternator, but it was doubtful with how well the car was running. Finally one of them said the battery was fine, the alternator was just too far gone to get a reading.

In my case I had a lot of the same hesitation while accelerating, intermittent dead batteries, and low power to accessories. Unplugging my radio actually helped make the hesitation less frequent due to the lower power usage.

Anyone with similar symptoms, at least for 1995-2006 years, I strongly encourage looking at/just replacing the alternator. It's cheaper on the Elantra than many other cars I've encountered anyway.

Stalling and stability light on dash at random

2017 Hyundai Elantra GLS 2.0l 109307 miles
For the last few weeks my car has at random times would stall at idle, when I would go to restart the car the stability light would appear and car would be in limp mode. If I shut it off and restart the car it starts fine and robes fine for a few days then it happens again. Took it to dealership to investigate and they say nothing wrong with car, not throwing codes.

Does it make a sounds when reving the engine. Ours had to get a whole new engine for a recall ours had.
Dave from Canada 2 years ago
There is no unusual sound and they ran a recall check nothing came up, it did it again today..

@DaveHave you checked the oil?
Dave from Canada 2 years ago
Had oil changed last month. Stalled on me again yesterday, put code reader on crankshaft sensor came up, but the code don’t stay long so when it does happen I can’t prove it to the dealership cuz they only go by what codes are being put out
ozdevil from Australia a year ago
This happened to me in my 2014 elantra recently , 1st time my mechanics code reader didnt pick it up and then just when i booked in for its service it played up at the mechanics and shown crankshaft sensor

So mechanic ordered a new sensor and was put in on the same day as service

Stalls when driving

1997 Hyundai Elantra 280000 miles
When driving and stopping, at a traffic lights for example, the engine stalls. A long time must be waited for the engine to start again. The vehicle was scanned and a coils failure was indicated, but they were changed and the problem persists.

Buddy, in the induction body there is a little membrane, which must be damaged or broken, causing the problem you are talking about. You need to disassemble
the induction body, clean it properly, remove the membrane and replace it by an identical, but new one. I hope you can solve your problem
one from United States 11 years ago
I have the exact same problem and would appreciate if you could tell us where the induction body is located as I cannot find it. Thanks!
bcbusiness248 from United States 11 years ago
Check the pcv valve, its on the valve cover had the same problem engine couldnt vent, pressure builds up causing hesitation and stalling, valve cover oil leak or other oil leak usually accompanies this issue.
GregZ from United States 7 years ago
Something to check is the voltage at the battery. The battery only starts the car and the alternator generates power. A battery is 12.6V or 12.8V when the car is off. When the car is running the battery is being powered by the alternator and you should read more like 14.6 volts on the battery posts. Easy to check with a multimeter. I had an exhaust leak under the hood and that was killing the alternator. Sometimes the alternator will make voltage and then sometimes it would be dead and the battery would get low. Something to look into is the alternator as this also doesn't throw a code to make a check engine light come on.

Smartblonde from United States 9 years ago
That particular year may have what they call an anti theft sensor in the ignition. Have you replace the ignition switch or has they key got wet or magnetized? You may need t9 have the sensor replaced in your fob or key. The sensor in the steering column isn't reading your key. So it's the car and your fault but not the kids

Engine failure

2014 Hyundai Elantra 31068 miles
Purchased new in 2014. All maintenance done according to recommendations. I have all paper work for oil changes. At 50,000 Kim's ticking in engine started. New engine installed in2016. Today I took my car in for engine ticking, told I needed a new engine. Mileage is 99,999 Kms. Unbelievable that a car would require 2 new engines by 100,000 kms. There is some serious engineering issues with this engine. Now I'm scared my car will catch fire or just malfunction and cause an accident. Hyundai needs to be held accountable for these problems. Major law suit in US. Looking to see if one has been started here.

Engine tends to stall or hesitate when moving after a stop (e. G. , at a traffic signal).
Instant pickup problem – feels like it's going to stop.
Sometimes has starting issues.
Normal driving (once moving) is okay.
Parts already replaced/serviced:

Crankshaft position sensor

Spark plugs

Fuel pump

Throttle body cleaned

Rough idle and shaking at stop after 60,000 miles

2018 Hyundai Elantra Sedan 65000 miles
Hi everyone, I drive around 65,000 miles, and recently I’ve been noticing a rough idle issue. When the car is stopped (like at traffic lights), the engine sometimes vibrates more than usual, and the RPM slightly fluctuates. It’s not stalling, but the shaking is noticeable inside the cabin. While driving at normal speeds, everything feels fine. There’s no check engine light on, and fuel consumption seems normal. I’ve already checked basic things like fuel quality and haven’t made any recent repairs or changes. Could this be related to dirty throttle body, spark plugs, or engine mounts? Has… Read complete

A rough idle at around 60k miles is pretty commonly linked to things like worn spark plugs, dirty throttle body, or even engine mounts starting to go. Since it only happens at a stop and not while driving, I’d definitely start with a basic tune-up and cleaning before assuming anything major. Hope you get it sorted soon!

Chasing a rough idle at stoplights will drain your patience faster than almost anything else. I went down that exact rabbit hole last year—replaced spark plugs, cleaned the throttle body, and swapped motor mounts, but the shaking at red lights just wouldn't clear up. Ended up taking it over to https://www.culvercitychevrolet.com/ to see what they'd give me on a trade-in instead. Sinking another grand into diagnostic fees on a high-mileage daily just wasn't worth the headache

Starting and running heat

2015 Hyundai Elantra 125000 miles
I went to heat up the car this morning before leaving and I turned it on and then turned the heat on and hit the rear defrost button and the car started jerking and idling very very rough almost about to die. I pushed the gas pedal a lil bit and kept the rpms up to about 2000 and turned the heat off. It never died but we literally haven't had this car a month and financed it. And when this happen I smelled something that almost smelled like paint thinner but maybe it was gas but it was a very strong smell. Any thoughts on what to check first or has anyone else had this issue?
