2022 Hyundai Elantra N

over the course of a year I get a "Transmission system error! Check Transmission oil Immediately" message. happened on April 15 2025, again June 20 2025 but car went into limp mode and did not go into 2nd and 4th gear. June 30 2025 went to dealership where ecu was reflashed.The problem went away but then came back on July 26 2025. Dealership could not see me during 2 weeks and by then message error cleared on its own. July 1 2026 message came on again and check engine light came on. Car again did not go into 2 and 4th gear and ended up stop moving. after leaving car off briefly and starting it back up and was drivable. Check engine light came on and I was able to plug in a reader and get code P0868. July second went to dealer and when car was driven into bay light went away. No scan was done to obtain code that was stored and dealer will not look at it. Escalated it to consumer affairs and they will not assist either. These are all symptoms from Recall 236 where the electric oil pump fails and puts my safety at risk.

Fuel injector randomly went out, I dont have the HPFP recall done on my car. Caused a massive amount of power loss while I was going down the road. Now hyundai wants to pretend like the HPFP had nothing to do with this. I keep being told its an emission part and isnt covered under powertrain warranty. Recall in question is Extension Z04 (TSB 25-FL-002H).

In Elantra N, the plastic piece (splash guard) under the engine is prone to coming loose and/or coming off while driving. This has happened to me and many many others. Its poorly manufactured, and fasteners (push pins) are really cheap. Part # should be 29110-IB000 The warranty doesn't cover this. This reddit thread has many people reporting same issue. Still there's no recall or TSB: [XXX] People are saying stuff like: "I was driving and the undercarriage guard just fell off. I ended up having to rip broken pieces off and zip tie the rest because I was in the middle of nowhere." Another person- "2022, during the next service the Hyundai mechanics went “Haha yeah, I’ve heard that happens…” and proceeded to do nothing about it." Another person- "Oh boy, this has been a sore spot for me... Mine came damaged when I bought the car, went through hell confirming part numbers, sourcing who had it cheapest (ended up being the dealer because all 3rd party Hyundai part sites want insane shipping for this), finally get it on, just for the same exact experience to happen at 75-80mph... Thought a tire was about to let go as the sound got more violent then CRACK. Realized what it was, then a second chunk broke off, and watched it almost boomerang into the car behind me 🤦‍♂️." For reference [XXX] n This causes part to drag and come off also causing potential harm to other vehicles. Could you make Hyundai recall this or something to come up with a better solution to this part ? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2022 Hyundai Elantra N. The contact stated while driving 40–50 MPH, the vehicle failed to accelerate as needed. The vehicle went into LIMP Mode while driving. The check engine warning light was illuminated. The contact related the failure to NHTSA Campaign Number: 24V528000 (Fuel System, Gasoline). The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The vehicle was towed to the same local dealer, where it was diagnosed that a software update to the fuel pump was needed. The vehicle was repaired, but the failure recurred. The dealer informed the contact that the fuel pump would not be replaced until the fuel pump had failed. The vehicle was repaired, but the failure recurred. The vehicle was taken to the local dealer again, where it was diagnosed and determined that the fuel injector had failed. The codes reference the fuel pump, and Oxygen sensor. There were pressure failures, and the engine was running rich. The vehicle was repaired, but the failure persisted. The manufacturer was contacted, and opened a case, but no additional assistance was provided. The failure mileage was approximately 20,000.

I was driving on the highway, got a flat tire. The second my tire popped. I started getting a few lights on my dashboard abs, forward safety light, limited differential light, blind spot light, rear cross traffic light. Worst of them all is a red steering wheel light which makes the vehicle difficult to steer. This is a new car with under 20k miles and it’s a lease. After the tire was replaced the lights are still on and the car is still non drivable.

This bulletin provides information related to a Transmission Control Unit (TCU) software update for some vehicles equipped with an 8-speed wet dual clutch transmission (8WDCT). The software update revises the touch point learning variation, improving drivability and judder symptoms. Certain 8WDCTs (indicated by a new part number) received an updated clutch spring. The correct TCU software update must be matched with the correct corresponding 8WDCT hardware, otherwise, drivability concerns may occur. This service procedure should be performed prior to any 8WDCT replacements done for drivability/judder concerns.

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.

Some 2019MY and newer vehicles equipped with a front view camera may illuminate certain warning lights and trigger DTC C272246 fault code for the front camera. In the following cases, the front camera auto-calibration range may be exceeded while driving: • If the front camera is not properly installed and is completely or partially detached. • In case of excessive changes affecting the vehicle's balance (e.g., loading excessively heavy cargo in a specific location of the vehicle, or significant under-inflation of the tires). • Specific road conditions affecting the vehicle's balance (e.g., excessive road crown) This TSB provides instructions on how to service the vehicle when the front camera related warning light(s) are triggered due to system out of calibration (DTC_C272246).

This bulletin provides information regarding condensation related to the accumulated moisture in the headlamp, rear combination lamp, daytime running lamp (DRL), or fog lamp. This TSB illustrates the various causes of condensation inside the lamp assembly. Lamp assembly replacement is NOT necessary in most cases. This condition can be eliminated by turning on the lamps with the engine running for several minutes or during normal driving operation.

This bulletin provides information related to the changes introduced in the 2025 1st Navigation Map and Software Update. The changes may vary depending on vehicle type, model, and navigation system as described in this TSB.
