2019 Hyundai Elantra

About two months ago, I had to replace the camshaft on my vehicle. Then about 3 weeks ago while driving down the road I began to hear a grinding slap near the front right of the vehicle. Then the power died and the vehicle limped into a parking lot. After stopping for about 30 minutes, I was able to restart the vehicle and get it home. The same noise occurred the whole drive. I couldn't start it again, and had it towed to my mechanic. The mechanic's review showed that the engine had seized up despite only being down a quart of oil. The engine was getting plenty of oil to give him confidence that missing oil wasn't the cause of the problem. The vehicle has about 104000 miles on it. To date, Hyundai refuses to even acknowledge that it's their problem despite a similar recall (21V301000) already being announced for this Elantra model.

The engine failed for my 2019 Hyundai Elantra. We bought it at Atlantic Hyundai dealership. They used a passing recall inspection to clear a defective engine, misdiagnosed the ensuing failure as an oil pan leak, and abandoned me with a vehicle that stalled dangerously in traffic. We brought car to Atlantic Hyundai told them that the car just stopped on the highway in the middle of driving. Our mechanic told me to tell Hyundai the car was rapidly consuming oil. Hyundai said oh no it’s just an oil pan snd we trusted them allowed them to fix it. Several weeks later the car completely stopped in middle of driving on exit ramp. Police came to make sure traffic was diverted so they could help me get car to side of road safely. It was towed back to my mechanic who said same exact thing car is dangerous bring it to Hyundai they need to fix this for you it’s the engine recall. We had it towed to dealership and after 2 weeks they said oh yeah you need new engine. We brought it to independent mechanic because Atlantic Hyundai knowingly sent me off in a dangerous vehicle the first time and no longer did I trust them with safety of myself and others on the road

The car was driving on the highway and out of nowhere the car just stopped in the middle of the highway. I brought it to my mechanic who said the car was rapidly consuming oil and my cars engine was seizing. and he safely brought me and the car to Atlantic Hyundai where I had bought the car to have them diagnose and fix the issue. After several days they diagnosed the issue as a simple oil pan issue and replaced the oil pan and sent me on my way. The same issue with the engine seizing up in the middle of driving on the highway endangering my life and others. I am still terrified thinking of this. We brought car back to Hyundai by tow truck because I was scared to drive it and after 2 weeks of waiting they then told me the car needed new engine however they never mentioned what I later discovered was a serious recall for this specific engine . Upon further research my car was listed under the recall however before I bought the car it says it passed the test to see if it needed engine replacement under recall 203 . They knowingly said my vehicle was safe they sold it to me knowing it was unsafe and then they put a bandaid ( oil pan) and sent me on my way knowing I was in danger. I am lucky to be alive because the car stalled out on a major highway .

At 86,000 miles After replacing the camshaft and timing chain with a mechanic friend, we turned the engine over and heard the beginning of an engine knock, he said this engine is notorious for knocking and failing before 100000. Kia recalled the exact same engine. However Hyundai did not. I feel this is very unsafe.

While driving vehicle on a highway exit ramp, the engine suddenly failed. There were no warning lights, messages, noises, or other signs before it happened. The vehicle lost power and became undrivable, which was scary and dangerous because I was still on the road near highway traffic. The vehicle had to be towed to the dealership. The dealership inspected it and said the engine had failed. I was given a repair estimate of about $9,100. I was also told the repair would not be covered under warranty and would not be covered under a recall. I believe this is a serious safety issue because the engine failed without warning while I was driving. If this had happened at a different time or location, it could have caused an accident or put other drivers at risk. The vehicle is currently undrivable, and the failed engine/component is available for inspection upon request

2019 Hyundai Elantra (VIN: [XXX]) suffered engine failure at 152,061 miles — abnormal knocking, loss of power, towed to Clay Cooley Hyundai of Sherman, TX. Diagnosed with crank/rod knock requiring long block replacement. This is the exact failure progression documented in NHTSA Recall 21V301 (Hyundai Recall 203): defective piston oil rings causing cylinder bore scuffing, accelerated oil consumption, connecting rod bearing failure, and engine block damage. Coverage was denied solely due to mileage — 2,061 miles beyond the 150,000-mile threshold. I am also reporting a critical discrepancy: a VIN search on NHTSA's website shows zero open or unrepaired recalls on this vehicle, despite the following facts: 1. This is a 2019 Elantra with a 2.0L Nu MPI engine — the exact population covered by 21V301. 2. The vehicle experienced the exact failure mode 21V301 was issued to address. 3. The dealership repair order references TSB 25-01-054H (tied directly to Recall 203) and performed an ECM software update under that bulletin during this visit. It is unclear whether this VIN was improperly excluded from the recall population, or whether the recall was marked remediated based solely on the software update — despite the engine already having suffered catastrophic internal damage. Either outcome warrants investigation. I am requesting NHTSA examine whether this VIN should have been included in 21V301, and whether Hyundai's practice of applying a software update to an already-failed engine and closing the recall is consistent with the intent of this safety recall. Repair estimate: $9,245.58. Vehicle is undrivable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.

In response to this trend, we engineered a software upgrade that addresses the social media theft method and made it available to owners of eligible models free of charge at authorized Hyundai dealers since early 2023. In addition to the anti-theft software, we’ve developed a new zinc-reinforced ignition cylinder protector hardware upgrade that can be installed at the ignition cylinder location to provide additional protection against the social media theft method. Because your Hyundai vehicle with the VIN listed above (“Subject Vehicle”) was not factory-equipped with an engine immobilizer and was previously eligible for the software upgrade, you are now eligible until March 31, 2027 to have the ignition cylinder protector installed — if you request it — at no cost to you through an authorized Hyundai dealership.

This bulletin provides the service procedure for installation of a key cylinder reinforcement protector assembly and two anti-theft decals on the front windows.

Upon customer's request ONLY, the Technical Service Bulletin (TSB) 25-01-089H provides the service procedure for installation of a key cylinder reinforcement protector assembly and two anti-theft decals on the front windows. This repair procedure is being provided in addition to the previous Anti-Theft software provided under Service Campaign 993 (TSB 24-01-009H-1).

In addition to the Anti-Theft software provided under Service Campaign 993 (TSB 24-01-009H-1), a zinc reinforced ignition cylinder protector hardware upgrade is being made available to customers upon request. This supplemental security measure is to be installed at the ignition switch location and provides additional protection against the social media theft method. Vehicles not equipped with an immobilizer during production at the factory are eligible. The repair procedure shall be performed and claimed upon customer request only. Any future repairs to these vehicles in which an installed ignition cylinder protector impacts required parts and/or labor, shall be covered by HMA. Please see TSB 25-01-089H for details.
