ELECTRICAL SYSTEM, ENGINE, FUEL/PROPULSION SYSTEM
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 cylinder walls in piston tops. There was significant carbon residue buildup but nothing out of the ordinary for similar GDI engines. I still performed a PEA GDI specific chemical cleaning. It was a a little smoother afterwards, but the misfire persisted and CEL remained on. I also removed, cleaned, and tested common sensor faults, with no result. Also p0128 code and no start / electrical drain, and engine light started flashing numerous occasions had to stop the vehicle. I tried swapping the coils, but all that proved was that the coil was good, I did a power and ground test, it passed the connector had 12 plus volt power and a perfect resistance to static ground. The signal wire from the coil connector had perfect continuity to the ECU but had OL to chassis ground showing there was no short. A test light was used to see if anything was coming from the signal wire to the ignition coil and that test failed, there was no signal pulse. The diagnostic process has definitively proven a component-level failure inside the engine control unit. See attached file for more detailed information.

LANE DEPARTURE: WARNING
The car has a "take a coffee break"warning light that dings when it comes on. It will randomly go off even if you don't leave your lane or cross a line. It's distracting and sometimes will go off if you have to veer around an object in the road making you think there's some other issue that you have missed, like a car beside you or something. Other times it will go off if you're just driving down the middle of the lane but wind is shaking the car, distracting you making you think there's an actual issue. There appears to be no way to turn this "feature" off and in traffic is very distracting and could cause an accident.

ELECTRICAL SYSTEM, STEERING, UNKNOWN OR OTHER
Horn is not working. After I hit 10k miles it suddenly no longer has worked, I am currently at 34250k miles and received a recall letter from hyundai themselves in case of any issues with the car but I don't have the paper. I went to dealer one time to give it a look but they were not working with me and treated me disrespectful so I gave up and been driving with no horn in car.

STEERING
The contact owns a 2013 Hyundai Elantra. The contact stated that while driving at an undisclosed speed, the steering wheel became inoperable. The contact stated that a cushion located within the steering wheel had deteriorated, causing the steering wheel to become difficult to turn. There was no warning light illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed that the steering coupler cushion within the steering wheel had failed and needed to be replaced. The vehicle was not repaired. The dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 50,000. The VIN was not available.

ENGINE
The engine in my 2019 Hyundai Elantra failed at approximately 66,000 miles. The vehicle began to idle roughly, lose power, and eventually stalled and would not restart. It was first inspected by an independent mechanic, who suggested a possible electrical issue. I then took it to a Hyundai dealership, where they later confirmed the engine was blown due to internal failure. I had a new warranty after refinancing, which required the car to be driven a minimum number of miles before coverage could be used. The engine failed when I was only a few miles short of that requirement. The warranty representative from the refinancing company confirmed in a voicemail that while they could cover work already completed (fuel pump), they could not cover the engine. The Hyundai technician also recommended returning the vehicle to the dealership for a new engine. The dealership had previously noted the vehicle was only a few miles outside warranty coverage and even suggested they could “drive the car a few miles” to make it appear within warranty , they said after they put the part in , it drove 3 miles and the engine gave out . They charged approximately $2,000 for a repair that failed, and the vehicle was never drivable again. Because the vehicle did not operate and I could not continue payments, it was repossessed. The loan balance I now owe is a direct result of the premature engine failure and unsuccessful repair. I later learned that 2019 Elantras with 2.0L Nu MPI engines have recalls and complaints regarding improperly heat-treated piston rings causing engine damage. My VIN did not initially show under recall, but this failure matches known defect patterns. There were no warning lights prior to failure; the engine failed suddenly. I believe this vehicle should qualify for recall or warranty coverage.

ENGINE, SERVICE BRAKES
The vehicle caught fire while it was in motion; there were loud bangs and a lot of noise, and smoke started coming out of the front, and the engine and the undercarriage caught fire.I managed to turn it off, but when they were towing it, the mechanics did the diagnostic and found wires were faulty and damaged the engine.

UNKNOWN OR OTHER
A safety recall performed by Hyundai automotive company was completed on 10.4.2022 to remedy a known security flaw in Kia/Hyunai vehicles made between 2011 and 2022. This recall was performed successfully by a certified Hyundai dealer. Since this, the vehicle has been stolen not once, but twice. The security sytem that should be in place to prevent the ease of theft has not been effective. This has put us as owners at risk of financial harm by lack of access to a vehicle on multiple occasions. Additionally this has continued to be a public safety concern as this has put the lives and safety of others at risk when thieves are easily able to steal these vehciles and drive recklessly around a city. The problem has been reproduced by a dealership when they had to store the vehicle, locked, and were able to start the car with just a USB stick in March 2024. Additionally this issue has been reproduced by a thief again in September 2025 when a second theft occured. The vehicle has been assessed for damage at a certified Hyundai dealership and is awaiting further inspection.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
While driving in the rain, car reported "Check Forward Safety System". Error has not gone away multiple weeks later. Hyundai dealer's first reaction was "Oh yes, this happens all the time" (!!) but then refused warranty repair because car is in other than pristine condition, despite being only two years old, still under warranty, with pristine front bumper. Without this sensor, adaptive cruise control, collision warning system, and automatic emergency braking do not work.

ENGINE
My engine blew in September 2024. I had it replaced. When I replaced it I got a one year warranty and unlimited mile warranty. It now blew in July 2025. I have had it hyundai of mankato which they didnt want to wait on hyundai of America to do anything to fix it and told my mechanics to have my car get offline their lot. My mechanics towed my car to Happy Hyundai of Rochester. HYUNDAI of America will not accept my warranty now and just pay for the new motor, tear down, and the time they have in it. Hyundai of America told my mechanics if they took it from Hyundai of Mankato and brought it to another dealership that they approve of that they would accept my warranty and pay for all parts and everything. Hyundai of America picked Happy Hyundai of Rochester. Where my car is.

The vehicle was towed to the residence, and the tow truck driver informed the contact that an unknown engine part had detached on the road and there was no oil in the engine. Jiffy Lube inspected the vehicle at the residence and informed the contact that they were not responsible for the engine failure, which was caused by a lack of oil changes after 10,000 miles. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 86,151.

POWER TRAIN
Vehicle started to violently lurch when shifted into drive. A week later loud clunking sound also started when shifting into drive. Sometimes would not go into drive and had to use manual 1st, 2nd, etc. Reverse was fine, no issues. No dash lights ever came on. Auto parts store had error code P0722. Have a diagnostic appt in a week at local Hyundai dealer. We may attempt to replace input/output speed sensor to solve, but probably will let dealership do diag first. Mileage approx 84686. Very dangerous at stop lights if can not get car into drive. Crash risk is high.
