2018 Hyundai Elantra owner complaints

I noticed around 100,000 miles that my car was going through oil when I heard a ticking in the engine. I pulled over and checked and there was no oil on the dipstick. No warning lights or nothing. I just kept adding oil after that and thinking that I will never buy another Hyundai again but never thinking my engine would fail full of oil. In June of 2023 my car lost power just as I got off the freeway. Thankfully it happened just as I got out of rush hour traffic otherwise it could have caused an accident. I had it towed home and the repair shop said my engine failed. I had it towed to a dealer and they confirmed that the engine failed. After many email and phone discussions with the dealership and Hyundai, they said they would cover 50% and then 70% of the repairs. The repair shop in town

I have a 2018 Hyundai Elantra with about 155k miles. It has been consuming oil excessively and has developed serious drivability issues. If I try to accelerate even slightly harder than normal—especially above 2,000 RPM—it makes a metallic, chain-type rattling noise, loses power, and produces heavy smoke from the exhaust. The smoke sometimes continues even after shutting the engine off and restarting. Because of this, I’ve been avoiding rapid acceleration and slowly working up to highway speeds. The car also periodically shakes at idle, idles higher than normal at times, and the RPMs will occasionally rise on their own. In the past it has stalled randomly, and sometimes it feels like the transmission is “stuck” and won’t shift properly. Despite all this, there are currently no check-engin

My car lost power on a busy highway which almost caused a tractor trailer to rear end me. I had the car towed and the mechanic said the engine is bad because of issues with this engine losing oil quickly and there is no recall on it but on other years. Now I have no car but still owe money on it and can’t get to work. Luckily i wasn’t hit by the tractor trailer but this should be a recall and i should be able to get it fixed without being out thousands of dollars.

It is showing signs of excessive oil consumption. 200 miles before my next scheduled oil change there was no oil in the car, causing overheating issues. It uses the same engine as other recalled years for the same issue. However they never issued a recall for the 2018. The only update I've ever received was a surprise notice from Valvoline, mid oil change, that if I didn't use the more expensive oil change option, which I couldn't afford in the moment, that I would void any warranty from Hyundai. There was no prior notice or contact from Hyundai informing me of this "New" (the valvoline tech's words not mine) policy. So not only is my car experiencing an issue known to affect this engine, they get to absolve themselves from responsibility by surprising someone with a greater expense than t

When I first purchase the car It was stated that i had no issues, I have records stating this. Also, I was having tremendous issues with the tires. Four months later I encountered an car accident. I was getting off of an exit and as I was getting off there was a car in the middle of the street that was broken down with no hazardous lights on. I suspected that the car was moving but it was not. As I am braking I was somewhat too close to the car and I ended up hitting the back of the car. At this time, the air bags did not deploy. Once the car was evaluated by the insurance company the car was considered totaled. The insurance company took the car to a salvage. This could have taken my life.

Had a car accident, airbags did not deploy but the airbag light was on. Insurance inspector said they inflated but did not come out of their housing. The airbags did not deploy upon impact. I attached pictures of the accident to show the airbags did not deploy.

I was in a car accident. I was hit on the passenger rear side and the car spun out of control but none of the airbags deployed. The vehicle has not been inspected by the manufacturer but we did reach out to them and are in the process of filling out a questionnaire. The vehicle is currently being assessed in a body shop as we work with the insurance to see the final damages.

I bought the car about a month ago. And today I experienced the car while driving at 55mph when I went to accelerate to go the speed limit of 65 on the major highway going into salisbury, md that the car wouldnt speed up. And about 30 seconds later the transmission seemed to have down shifted a couple gears due to the rpms going from 4600ish RPM down to 2000 rpms and than the car went back to normal. When I had gotten into salisbury and had to stop it braked just fine but when I started to drive again it start to feel like it was stalling and it's been doing it now for the whole day. As well as a burning smell which I'm 99% certain is the clutch. I have worked the automotive field for about 7 years. I have a DCT transmissions 2018 Hyundai elantra sport tech package. I went in the forum on

What component or system failed or malfunctioned, and is it available for inspection upon request? The car began stalling and started to become unresponsive while I was driving to work. While I was not 100% sure of what component was malfunctioning at the time, I suspected that it might be a timing chain problem because I had this same exact issue happen to to this car back in January 2025. I did not expect this issue to occur again because at the time of the previous problem, the dealership confirmed that issue was the timing chain and the VVT system, and replaced those components with new parts. How was your safety or the safety of others put at risk? The car started stalling and sputtering, then became unresponsive while I was driving. If I were in a high-traffic area, I'm not confiden

My daughter is in college in Tallahassee. About 4 months ago, she told me that when she presses the accelerator, the car doesn’t go as fast as it should. In July 2022, the car was serviced in Tallahassee at the dealership; however, none of this is reflected on the receipt. In November she came home to Palm Beach County, on her way back, she told me that she was having the same issue when she pressed the accelerator. She made it to Tallahassee and I had her take it to the dealership. The Service Manager called me and said she had gone over the recommended miles for an oil change and this may have caused damage to the engine; however, he decided to change her oil and spark plug which coated about $318. She drove the car for a few days and noticed a loud tapping noise; also, the car rolls in

My car was stolen because of how easy it is to start it without a key.

Initial Fault Code: P0303 Replaced all 4 spark plugs and all 4 ignition coils. The check engine light extinguished momentarily but returned, logging P0303 and a new P0301 Replaced all 4 fuel injectors. CEL extinguished momentarily and then returned, logging P0303. Replaced the entire engine electrical harness. Concurrently, all related electrical components and connectors were meticulously cleaned with professional contact cleaner. CEL extinguished for significantly longer period of time, and then returned, re-logging P0303 and P0301. Thid suggested the ECU was "handshaking" with new components but re-logging the fault upon detecting the persistent core issue. A full compression test was performed. All cylinders reported results within specification. Using a borescope I inspected cyl

Car isn’t starting just changed the started two years ago after it failed now it’s not starting we have gas in it and it won’t start

Since my car had 7,000 miles, I am experiencing a creaking sound around front wheels when turning at slow speed, more so when on uneven pavement.

Tire pressure sensors and/or TPMS module problem. I purchased this 2018 Hyundai elantra from san tan Hyundai, gilbert, az 86297 in late march 2018. The tire pressure in each of the 4 tires was 36 PSI, the cold tire pressure for this auto.in the first week of august 2018 the tire pressure warning light on the dashboard came on . I checked the the tire pressure in each of the 4 tires with a analog and digital tire pressure meter and the pressure in each tire was about 32 PSI. I re- inflated each tire up to 36 PSI (spec requirement) but the warning light stayed on. I notified Hyundai headquarters customer service about the problem and they assigned a case number and suggested I take the new auto with only about 1500 miles on odometer to san tan Hyundai. I had to wait about 2 weeks for a oct.1

The rear lights, brake and tail lights , burn out frequently. Had it repaired twice in less than 6 months

While driving at low speed (25mph) I could hear a sound coming from one of my tires that sounded like I had rolled over a large piece of tape. I slowed the car and it sounded like something was stuck on a tire. I pulled over and found nothing when I examined all 4 tires. In the morning I checked the tires and tire pressure was good on all 4. Drove to work and I could hear the fapping sound. As I was driving 55mph, the drivers rear tire blew apart into small 2" square pieces. The tire fragments tore through the fender-well, destroying it as well. This happened early in the morning and I was able to keep control of the vehicle. Westlake RP18 size 195/65/R15. Less than 6 months old and under 15,000 miles on them.

Car sputters at idle, acting like it's going to cut off. Does not accelerate properly, but only intermittently. One day, the check engine light came on and I could not accelerate and it would sputter at lights. Drove it straight to advance to get the engine light checked; nothing came up. Started the car again and it drove fine, like nothing had happened. Took it to the dealership the next day. They couldn't duplicate the issue. Finally, after letting it idle awhile, were able to get a code on the coils. Replaced them all. Car was running fine after that. The sputtering at idle has now started again.....less than 2 months later.

White paint peeling in less than 3 years of ownership. Jenkins Hyundai of Leesburg said they would put in a claim, but they have been non-responsive after saying they would put in a claim. No action from the dealership. The manufacturer, Hyundai, who painted the car, has also not taken any action, and have deferred the problem to the dealership. The paint should have been covered under warranty.
