The contact owns a 2020 Hyundai Elantra GT. The contact stated while driving 5 MPH in stop-and-go traffic, the engine light illuminated. While driving, the vehicle stalled. The vehicle was towed to the local dealer, where it was diagnosed that the knock sensor needed to be replaced. The vehicle was repaired, but the failure recurred. While driving at 35-45 MPH three days later, the engine light illuminated again, and the vehicle started to decelerate. The vehicle was towed back to the local dealer, who performed a combustion test. The dealer requested permission for a mechanic to take the vehicle to the residence for a road test. The contact declined the request. The manufacturer was contacted and opened a case. The contact requested a buyback. The failure mileage was approximately 29,000. The VIN was not available.

Tire size: 225/4R18 88W Code 2119 indicates manufacture on 21st week of 2019. Factory original equipment on a 2020 Hyundai Elantra GT (N-Line). At the dealer for an unrelated service at approximately 37,000 miles. Tech noticed cracking on sidewall of all original tires. Suspects it is dry rot. There is a previous recall for these tires in a different size from 2015, but it appears the issue has not been resolved. I've attached a photo as an one example of the cracking. All original tires have multiple cracks like this along the sidewall.

My 2020 Hyundai Elantra stalled on me in the middle of driving it. Only check engine light was on. Had an oil change three months prior to it stalling and not wanting to accelerate. Made an appointment with dealership, they stated it would be fine to drive for another month and a half when they were able to get my vehicle in to look at it. Spoke with guy on phone said there was no recalls, which was a lie. Because last year it had a campaign opened on it that i knew absolutely nothing about, on top of the three recalls on it. My car did not make it in time for the appointment. The engine blew up even though it had another oil change a week before. Dealership wants to blame me. Hyundai National also refuses to accept that it is something malfunctioned bad in the engine that is a safety hazard. I believe the piston rings were bad. Theyd rather blame me because i went over my miles for an oil change the first year i bought the car brand new. Also it had a recall when i bought the car. To my knowledge its illegal to sell anyone a brand new car with a recall on it. Thank god i didnt injure anyone or myself when the vehicle died on me in the middle of a turn with traffic coming behind me. Also i have a full platinum warranty that they refuse let me use. They do not care about their customers. This is also a second car i have bought from this dealership. The first one had a recall on it. It was a kia optima, the dealership did not tell me they are suppose to pay to fix it, instead i traded it in for this piece of crap.

Some vehicles equipped with internal combustion engines may exhibit higher-than-expected engine oil consumption. This bulletin outlines the combustion chamber cleaning procedure for vehicles diagnosed with this condition. All internal combustion engines consume some engine oil during normal operation, depending on driving conditions and mileage, and this procedure should only be performed when deemed necessary based on inspection and diagnosis of the vehicle as outlined in TSB 26-EM-015H, Engine Oil Consumption – Inspection & Repair Guidelines, or the latest revision.

Certain vehicles equipped with internal combustion engines may exhibit higher-than-expected engine oil consumption. This bulletin provides the inspection and repair procedures for vehicles exhibiting this condition. All internal combustion engines consume engine oil as part of normal engine operation. Oil consumption rates may vary based on mileage, operating conditions, driving habits, and maintenance history. Hyundai recommends following the prescribed maintenance schedule and periodically checking the engine oil level using the dipstick to maintain proper engine oil level.

Some vehicles may exhibit difficulty starting in cold weather. This bulletin provides the procedure to perform an inspection on the starter magnetic switch for potential freezing and, if necessary, replace the starter magnetic switch (solenoid) assembly.

The National Highway Traffic Safety Administration (NHTSA) has identified the presence of substandard and dangerous driver’s-side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN). These inflators were not supplied, approved, or authorized by the vehicle manufacturers and have primarily been found in vehicles that previously experienced a crash and underwent airbag replacement using non-genuine parts. These dangerous inflators have ruptured during deployment, posing a serious risk of injury or death due to metal fragments entering the vehicle cabin. To date, Hyundai is aware of three people who have died while driving a Hyundai vehicle with one of these substandard replacement airbag inflators that deployed in what likely would have been a survivable crash. NHTSA has issued a public advisory urging vehicle owners and service professionals to have vehicles inspected if there is reason to believe that a non-genuine replacement airbag may have been installed. Vehicles with salvage or rebuilt titles, prior airbag deployments, or unknown repair histories may present a higher risk. NHTSA strongly cautions against self-inspection by vehicle owners and recommends inspection by trained technicians.

The National Highway Traffic Safety Administration (NHTSA) has issued an urgent safety advisory regarding dangerous, counterfeit driver‑side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN), that have been identified in U.S. vehicles following prior crashes, theft, or non‑certified airbag replacements. These inflators are not approved for use, may rupture during deployment, and have caused serious injuries and fatalities. Please see attached announcement, provided by NHTSA, for more details.

This TSB references the Op codes to use for claim submission and the Parts required based on the vehicle’s inspection results from TSB 22-01-023H (DTC P1326 – Engine Bearing Inspection/Engine Replacement) or the latest version.
