Selected complaints filed with NHTSA by 2015 Hyundai Elantra owners, lightly cleaned up (personal details are redacted by NHTSA).
The car was working fine. Then one day it wouldn't turn on while we were out. The engine wouldn't start and it smelt burnt and there was smoke. We had to jumpstart the car and it showed some codes. They were B1319 and B1111. We took it to an electrician and it showed there was was a fuse that's being overpowered. The car had been working again, but I did get a smell of something burnt a few times from inside the car. A few weeks passed by and three days ago the car again wouldn't turn on. Just yesterday I found out about the recall from September on the Hyundai Elantra 2015. Not sure if it has something to do with that, but I still haven't received a recall although that's the car model I have.
The contact owns a 2015 Hyundai Elantra. The contact stated that while driving at various speeds and making right or left turns, the vehicle inadvertently shut off. After restarting the vehicle, the vehicle operated as designed. The contact stated that failure also occurred while driving straight. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure, but no assistance was provided. The failure mileage was 54,000.
Odometer Fraud. The contact purchased a 2015 Hyundai Elantra. It was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was approximately 182,204 - 215,000; and at the time of registration, it was discovered that the mileage was 152,572.
On February 17, 2023, my vehicle was broken into and damaged because thieves tried to highjack the car using a now common method of the end of a USB cable in the ignition. The passenger rear window, the steering column, and the key ignition were all damaged, and I had my vehicle towed to a Hyundai dealership. Nearly all 2011-2021 Kia and Hyundai vehicles are made easy to operate without a key, to steal, and to vandalize. This security vulnerability has resulted in Kia and Hyundai owners paying for repairs (even with insurance, owners need to pay the deductible) and higher insurance premiums. Hyundai and Kia did not disclose this defect, which is a material fact, and a fact that a reasonable person would rely on when purchasing a vehicle, consequently making these vehicles easy to steal, unsafe, and worth less than they should be. …
Within three months of purchasing this vehicle, I started having engine light and oil consumption issues. Within the 4 years of owning, they've replaced the catalytic converter twice, many valves, and others. I had to purchase and add multiple quarts of oil to just maintain oil levels. I've had multiple occasions where my vehicle slowed to only up to 55 miles an hour while on the interstate. The vehicle had issues accelerating where an accident almost occurred because pulling into a shopping plaza, the vehicle couldn't drive up a minor hill and almost remained in the intersection. I've had multiple times where I was stuck on the side of the road in different environments, a few of which I was genuinely worried for my safety. …
Due to CDK Global cyberattack, I cannot complete my safety recall of my Hyundai Elantra 2015 (ABS Fuse that can cause engine to explode, according to Hyundai safety recall report). Hyundai does not allow dealerships to keep safety recall parts on hand (or a very small amount). I have to walk into the dealership to order the part. I cannot call to order the part. I have to constantly drive to place of work, home, sit in traffic, with a defective fuse that HyundaiUSA refuses to keep safety recall parts on hand. Please create a NATIONAL policy against manufacturers to have a minimum units (1000 units of fuses, parts, etc) as the safety recall occurs. Because dealerships cannot order parts due to this cyberattack. …
The engine failed on a 2015 Hyundai Elantra with approximately 71,000 miles. The vehicle has an open, unresolved safety recall (Recall 251, NHTSA #23V651000) for an ABS module brake fluid leak that Hyundai has acknowledged but has not provided a remedy for. The vehicle is currently at an independent repair facility and is available for inspection upon request. The vehicle repeatedly shut off without warning while in motion and restarted mid-drive, causing sudden loss of power steering and power brakes while driving. This occurred on multiple occasions and was documented by an independent service center in February 2026. This presents a serious risk of accident, injury, or death to the driver and others on the road. The check engine light was illuminated. …
Reporting my previous VIN in case it helps the new vehicle owner since I am sure they are facing similar defects that I am with my "brand new 2016 Hyundai Elantra". I previously owned a brand new 2015 Hyundai Elantra and had to file a claim after flooding occurred in Kyle, Texas. The 2015 Elantra title was transferred to USAA after filing a claim for TOTAL LOSS due to engine flooding on [redacted]. Odometer reading on date of total loss is 7,673 miles. Vehicle appears to be sold again with same odometer reading January 2016. Both of my Hyundai Elantra's were purchased at Ron Carter Hyundai Dealership in Texas (Dealer number P113588). This dealership is now called Big Star Hyundai after DCG Acquisitions represented the sale in 2021 - just in time to deny and delay warranty covered defects to consumers who thought they purchased a brand new car. …

At any given time without warning the car dies. There is a red light that is sometimes visible on the dash but flashes too quickly and tell which light it may be (due to location of light owner's manual showing possible oil light/battery). The car has had regular scheduled maintenance. This happens when driving in everyday traffic and sometimes when going from stopped to accelerating. This happens when going in reverse or ahead. I have almost been in several different accidents due to it dying in the middle of intersections. Code reader has not been able to locate the problem because there's no indication of a problem on the check engine light. This is a very serious problem that needs to be taken seriously before it gets someone badly injured or killed.
