2013 Hyundai Elantra: misfire or rough idle

Filed Mar 16, 2024 · Engine · MN

After taking my 2013 Hyundai Elantra in for service at a local mechanic due to hearing a new engine sound but no check engine light, I was informed that there was a much bigger problem involving a misfiring cylinder requiring a brand new engine replacement. My mechanic directed me to take in my car to a local Hyundai dealer where I was made aware that this was a known issue with Hyundai Elantras but was never made a recall leaving owners to hope that their vehicles fell under an arbitrary warranty extension that was put out by Hyundai [XXX] ) If undiagnosed or not replaced this can cause an engine seizure which could in turn lead to collisions, accidents, injury or death. I have entered my VIN into the website provided which tells me that my vehicle qualifies, however after taking my car into the dealership I was informed that my vehicle will not be covered since I bought the car pre-owned and it has been over 8 years since the manufacture of my vehicle. So because I fall out of that range I'm unable to have a known issue fixed that should be a recall? How does that make sense? My car has now been at a local Hyundai dealer for over two weeks with Hyundai Corporate kicking the tires on getting back to the service department on if they will cover any portion of the new engine. This has caused major issues and impediments in my daily work and personal life as I've had to rearrange and work around transportation.

Confirmed the customer's complaint &found the engine didn't start. Inspected the ignition system & the air intake system, but found no concerns. Inspected the engine coolant level & condition & found the engine coolant level was fair. Filled the engine coolant to the proper operating level & continued diagnosing the vehicle. Connected an engine coolant pressure tester to the radiator & pressurized the engine cooling system to check for leaks. Inspected the engine cooling system & didn't find a leak. Removed the spark plugs for inspection & found the spark plugs were contaminated but Ok. Perform inspections of the engine compression & found compression was low. Under 60PSI. Prop the wiring to the starter & found signal was present & the starter cranks but the engine would not turn over. These results verified that Some internal components in the engine have failed. *NOTE: Found ignition coil cylinder 1 fault, causing P0301. Misfire. Replace with new ignition coil pack The tech inspected the engine. Found no obvious fault. No warning indicator. The computer shows the engine is running normally. He did check all the components & found a couple that was weak or will be going bad soon. The ignition coil for the remaining 3 cylinders is firing slightly weak. There are 4 coils, you replace 1, the remaining 3 are from the old engine, original until now. He's recommending having those coil packs replaced. That's helped the spark plug fire more properly. Also, the oxygen sensor on the exhaust pipe. the reading shows the O2 is switched late, meaning the electronic sensor is getting weak. It will fail soon, once it does, it will set the engine light .Engine Mounts: Right: With the engine at idle, performed an inspection of the engine compartment and found the engine shook. Turned the engine off & performed a visual inspection of the engine compartment & found that an engine mount was weak or damaged. The issue has been ongoing for months prior to this issue.

Recently my car has had trouble starting, and the engine has sounded weak while running. While out my engine light came on the dash. I took my car to the parts store and they put the computer on to read the engine light. It stated that there are misfires in the coils. Yes it is available for inspection upon request. This put people inside the car at a risk as a engine failure couldve happened at full speed. No this has vehicle has not been inspected. My dash had zero lights on, until the engine light came on. This is my daily driver and can not afford this vehicle to be down.

I've been driving this vehicle as a secondary owner since 64k miles, it's now at about 71k. I keep up with maintenance regularly, but lately it's developed a bit of a noticeable ticking especially when cold, and idles pretty rough when cold, seems to get better as the vehicle heats up. 3 times, all spaced out by a couple of months I've also experience a refusal to start, trying again usually gets it to start but one of those times it almost sounded like it was misfiring since it seemed to stumble and nearly stall. I've taken it to two shops and not one of them and has been able to determine the underlying issue like it's not even there, one of them only suggested a battery replacement which funny enough seemed to help it until recently, will be taking to hyundai soon perhaps but I see a trend of very similar symptoms on here.

I'm having serious engine problems at only 44k miles including failed ignition coils & sparkplugs-now engine still misfiring & coils going bad one at a time. I'm a single mother & cannot afford engine repairs especially with this low of mileage on the vehicle & after just purchasing it used from carmax in amherst, ny at end of january, 2019. I was told by the repair shop that the ignition coils are defective. Thank you.

About 3 months ago my 2013 hyundai elantra became sluggish in accelerating. It has gradually gotten worse. I tried fuel cleaners, premium gas, and now a tune up replacing coil packs and plugs. The vehicle crawls and does not accelerte as quick as it should. It cuts off or refuses to move when given gas at all stops. I switch off then on at red lights as it seems to want to take off when the engine is started. When I reach about 50mph the RPM hand guns and the bottoms out to stay at zero with no change in acceleration. There is now a whirring noise sporadically coming from the engine. After the ti e up the issues continue with cutting off ,rough idling, extremely slow snail accelleration with the engine light on.

Intermittent engine light illumination. Happens only after the "vehicle check in progress". Car has started to run rough both while accelerating and at a stop. Acts like it will shut off. Having to put the car in neutral and pat the gas to keep it running. There is a tsb for this issue but no active recall. Constant run around at the service centers. They say its normal for it to run rough. Also the rubber steering coupler went bad. Was making a thud noise when steering wheel was turned. Also a tsb for this....no recall. But wait theres more! The clock spring is also bad! Tsb for this too! Bad clock spring results in the loss of power to the buttons on the right side of the steering wheel. When I replaced the steering coupling, I forgot to plug in a wiring harness under the wheel and the buttons started working again but had no power steering. Plugged the harness back in and had steering but the buttons no longer worked. Pretty sure hyundai is uploading error codes and giving people the run around in an attempt to get more money. Recall this crap already before something bad happens. Hold this company responsible for selling crap to people.

At 60k miles, a knocking sound came from the engine after rough idling. The engine oil now has metal shavings. Dealership denied that there have ever been problems. Never missed an oil change. Trying to get dealer to cover under warranty.

Around 40,000 miles the car randomly would not start, leaving me stranded. I took the car in several times and dealership could not detect an issue. 2nd time I dropped off, a misfire was detected and ignition coils where replaced due to defected coils. I picked up my car and 11 days later the car wouldn't start up again. Its been in the shop for 3 weeks now. Last I heard they are replacing: the shifter assembly, transmission range switch, and brake switch. I have yet to hear if the parts came in and if this will fix the issue. I received a call on 11/3/2016 and now the engine needs to be replaced. There is a serious issue with the car failing to start and hyundai cant even figure it out, as of today they had my car for a total of 25 days and still no resolution. Something needs to be done and recalled. Ive contacted hyundai consumer affairs directly and have a case with them going on. I see several complaints of this same issue happening on this model, I hop this will somewhat help. Be consistent and don't take no for answer, I am still making car payments on something that is not working nor I have is unfair. Since the car is less than 60,000 miles this will be covered under warranty, it should of had to take me 3 times, calling a manger and going to consumer affairs for them to finally take my issue serious.

My 2013 elantra's engine recently stalled and now needs to be replaced, and the underlying problem as explained to me by the hyundai service dept. Sounds extremely similar to the problems that LED to the recent sonata recall. Here's what happened: I was sitting at a stoplight when I heard a strange clicking/knocking noise from the engine. The vehicle began to have a very rough idle, shaking noticeably. The engine then stalled. After about 30 seconds of trying, I was able to start the engine again but still experienced a very rough idle and the check engine light had turned on. I took it to the hyundai dealership. After the service department had looked at my car, they told me the engine needed to be replaced and that they were going to file a warranty claim. I was told that the engine bearings had failed, and that when they don't work properly to reduce friction in the engine, metal shards can get into the engine and cause problems. As I understand it from reading about the recent class-action against hyundai, this sounds virtually identical to the problems with the sonata engines that ultimately LED to the recall. I am still waiting to hear about the warranty (I'm still under the full 5 year/60k miles cpo warranty), but wanted to report this issue since what I've been told is so similar to the issues with the sonata engines. If the warranty claim is denied, I plan to request documentation of the problems with the vehicle and will be happy to provide them to the federal safety agency.

Pulled over to shoulder on florida turnpike to adjust seat belt and the car started a very rough idling and would not engage in drive. Reported it to dealer and hyundai motor america and following was their reply: -dealer: this is a characteristic of these vehicles that they don't know how to correct -hyundai: they are aware of the problem and are working to resolve it. In the meantime I am driving a car that is not reliable to me from a safety standpoint and two dealers in miami, doral and lehman hyundai service managers have told me that there is nothing they can do until the factory tells them how to correct the issue, your assistance will be very much appreciated.
