2019 Hyundai Elantra

The contact owns a 2019 Hyundai Elantra. The contact stated that while stopped in traffic with the vehicle idling, the vehicle vibrated, and the check engine warning light illuminated. The contact stated that for the rest of the drive, the vehicle failed to accelerate as intended while depressing the accelerator pedal. While the contact was entering a driveway, the vehicle stalled. The contact waited for several minutes before being able to restart the vehicle. The contact then drove to the residence. The vehicle was taken to an independent mechanic, where it was diagnosed with engine failure. The independent mechanic informed the contact that the engine was making an abnormal rattling sound and the piston oil ring had failed. The vehicle was not repaired; however, an oil change was performed. The contact called the local dealer and was informed that there were no recalls associated with the VIN. The manufacturer was not made aware of the failure. The failure mileage was approximately 126,000.

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.

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.

Subject: 2019 Hyundai Elantra – High Beam Headlight Failure and Warranty Denial To Whom It May Concern, I am writing to document and request review of an ongoing issue with my 2019 Hyundai Elantra regarding an inoperable high-beam headlight system and the handling of my warranty claim. Shortly after a warranty period service, my vehicle’s high beams stopped working correctly. I reported the issue to my Hyundai dealership as soon as it occurred, while the vehicle was still within warranty coverage. The vehicle was inspected by Hyundai, but the warranty claim was denied without a satisfactory explanation. Following Hyundai’s denial, I filed a complaint through the BBB Auto Line, providing the same information and documentation, but the claim was again denied. After researching further, I discovered that Hyundai has issued a service campaign (T5G – Headlamp High Beam Repair) for certain 2019–2020 Elantra models addressing the exact same defect—an inoperable high-beam function due to failure in the headlamp assembly mechanism. Multiple owners have reported identical failures online, and the campaign documents confirm this is a known defect. Because my vehicle clearly exhibits this same defect, I believe my Elantra should be covered under the same campaign or under warranty/goodwill coverage. The failure occurred under normal use, and I reported it promptly. I am requesting: A review of my VIN and confirmation of whether it falls under Service Campaign T5G (Headlamp High Beam Repair). If excluded, a written explanation for the denial and a reconsideration under warranty or goodwill repair. Clarification of why this known defect is not being covered when it matches the campaign description exactly. I am providing this information in good faith and hope Hyundai will stand by its quality and customer service commitments.

My high beam lights have malfunctioned and no longer work. The light on the dash states that my headlights are on but they just flick on for one second and discontinue to work. I live in a rural area and can not see at all when leaving home in the early am hours or when returning home in the evening. I've had to stop on the side of the road at certain times, because I have no visibility. My car is approaching 6 years old with less than 70,000 miles and this is ridiculous. The dealership is charging over 2,000 dollars to fix this issue and I think this is highly unacceptable for a car of this age, especially when I bought the car brand new. I bought a brand new car to avoid issues such as this, but I have seemed to pay the price but not receive the safety that I have paid for. There are so many complaints online for this exact issue. I would highly appreciate if safety is held as a priority for this issue and you all place this as a recall ASAP.

In or about December/2022, I had made numerous attempts to fix my vehicle's engine. It kept stalling on the roadway and finally Hyundai agreed the motor was the problem and they ended up installing a new motor. The vehicle was then out not warranty and they said they were not responsible for the vehicle any longer. The vehicle's check engine light kept coming on and off at times. I did minor work to the vehicle and kept up with maintenance. Now my vehicle's motor is blown again without notice. It stalls on the highway and leaves me stranded. I believe that this type of vehicles were flawed from the beginning. I really convinced these vehicles should be recalled and taken off the highways since, in my opinion, they are not safe to be on the road.

I've replaced the headlights 4 times and the daytime running lights 20 times! Bought and installed 2 entire headlight assemblies... 5 days later right headlight blew out. Ive entered many complaints about this 1 vehicle and conveniently for Hyundai NO recalls!!!! Continuous oil level issue reported the very first time I put the car in the shop.

The Knock Sensor Detection System (KSDS) software malfunctioned by failing to detect abnormal vibrations or knocking sounds. As a result, there was significant internal engine damage that caused the vehicle to seize unexpectedly in the middle of traffic on 4/10/25. The car started and abnormal noises were noted from the engine though not significant. week later, car stalled several times on interstate. Prior to the failure, the vehicle exhibited a progressive knocking noise in the engine. After seizing, the vehicle would struggle to start, idle briefly, then stall. It also randomly shut off while driving, creating a serious safety risk. The vehicle was taken to Precision Tune Auto Care, where technicians confirmed problems with the crankshaft, excessive oil consumption/leakage, and metal shavings in the oil, which they attributed to rod bearing and crankshaft wear consistent with Hyundai Campaign 203 (improperly heat-treated piston rings). Despite the KSDS being installed during the initial recall remedy, the system did not activate prior to engine failure. Additionally, no engine or oil warning lamps were illuminated. An oil change was performed at the time, but the vehicle had already burned through excessive amounts of oil since the prior change. Precision Tune Auto Care advised me to take the vehicle to Allen Turner Hyundai. At the dealership, staff confirmed issues with the engine but refused to acknowledge Recall Campaign 203, even when presented with documentation. They also failed to address the malfunctioning KSDS system or the lack of functioning engine/oil warning lamps. They were asked to perform inspection relating to piston ring and rod bearing, though refused. This situation raises major safety concerns, as my engine seized in the middle of traffic without warning. Other owners with a malfunctioning KSDS system could face the same risks, leading to sudden engine failure, potential engine fires, or serious traffic accidents.
