2025 Hyundai Elantra N

To the National Highway Traffic Safety Administration I am submitting this formal safety complaint regarding a persistent and dangerous pattern of mechanical and electronic failures in my 2025 Hyundai Elantra N. These issues have rendered the vehicle unsafe for regular operation on public highways. The safety concerns began at 2810 miles when the vehicle first showed signs of structural and electronic instability. Since that initial mileage the vehicle has demonstrated a progressive inability to maintain its steering and alignment specifications which has led to unpredictable and hazardous driving conditions. By 16550 miles the steering issues became severe. The vehicle intermittently began to dart to the left or right without driver input. A diagnostic alignment check at that time confirmed multiple values were out of specification including the right front and right rear toe. These red zone readings were documented by the dealership machinery but the root cause was not corrected. Along with the steering failures the electronic systems began to malfunction. The steering wheel buttons and drive mode memory settings started resetting randomly which prevents the driver from reliably controlling vehicle configurations. As of February 28 2026 at 18037 miles the condition of the vehicle has deteriorated further. The steering system is now physically incapable of holding factory specifications for more than 30 days. In the last 1487 miles the alignment shifted from the right side of the car to the left side with the left front and left rear toe now showing failing red values. This mechanical instability causes the vehicle to wander and pull aggressively. Most critically the electronic safety systems are now failing. The Lane Keep Assist functionality frequently deactivates itself without warning or external cause. When this safety feature shuts down it often coincides with the car darting toward other lanes.

On January 10, 2026, I purchased a brand new 2025 Hyundai Elantra N with manual transmission. At approximately 517 miles, the vehicle experienced complete clutch and transmission failure and was towed to the selling dealership. The dealership diagnosed the failure and presented a repair estimate of $6,222.96, classifying it as "customer pay/user error" and denying warranty coverage. Parts identified for replacement included the clutch cover assembly and flywheel assembly. I did not authorize any repair. I escalated to Hyundai Motor America corporate, who confirmed the dealership had not responded to their warranty inquiry for over two weeks. On February 18, 2026, Hyundai Motor America's National Consumer Affairs formally denied my warranty claim in writing, stating the clutch failure was due to "improper operation" and classifying it as external influence rather than a manufacturing defect. A complete clutch and flywheel failure at 517 miles on a new vehicle represents what I believe to be a manufacturing defect. No evidence of abuse or improper operation was provided to support the denial. The vehicle remains unrepaired at the dealership with no loaner vehicle provided and no resolution offered.

After my recent software update Elantra N I have had issues with my n buttons on my stearing wheel will random default to factory setting and I have to go back into the settings to reset how I have it set. I also have been having my exhaust valve randomly open and stick open it doesn’t respond to drive modes and stays wide open I look in exhaust and confirmed it is stuck open. When it’s stuck the car will not pop or anything. In ordered for me to fix it I have to pull over and plug in a obd2 scanner that I had to go out of my way to purchase. From there I have to put it in acssesory mode and do an active test on the valve which basically opens and closes it. There is no code on the scanner. And sometimes tha still won’t work I have taken it in to my local Hyundai dealer on multiple occasions and still have not had my issue resolved they ordered a spring it didn’t work I also had a new valve motor put on and still hasn’t fixed the issue. My dealer has said they cannot replicate it. It does it every drive. And had only started after the new update. As the car comes loud from factory when valves open I have been having to pull over and attempt to reset before going into my neighborhood as I have had neighbors complain of noise.

The "consider taking a break" alert is way too sensitive and there is no way to turn it off. It's distracting while driving with lights and chimes for no apparent reason. If there were a way to shut it off there would be no issue.

I was driving down I-45 mid day on October 14th, 2025 going about 65-70MPH and out of no where I hear a loud gunshot like noise and about a minute or two later I heard my sunroof crack and glass fall in. I believe it is from nickel sulfide inclusions

“Consider taking a break” pops up constantly, especially if you’re driving through construction and just in general. It’s distracting to have to ding at me every 5-10 minutes. It will turn down my audiobook on CarPlay and make me miss information ad well as impacting my GPS giving direction. It’s pointless, frustrating, and I can’t turn it off. It should be optional.

I bought a brand new 2025 Elantra N at a dealership in IL. It had 25 miles on the dash and still had the plastic on it. We tried to drive it home and there was no A/C. The local dealership in MS inspected it and it needs a brand new evaporator core. They said it came from the factory needing this repair.

This bulletin provides information related to the navigation and head unit software changes introduced in the 2026 2nd Navigation Map and Software Update. The changes may vary depending on vehicle type, model, and navigation system. Refer to the 2026 2nd Navigation Map and Software Update Key Improvements and Additional Improvements tables in this TSB for a list of specific changes. The software can be downloaded via Navigation Updater (NAU) and updated by USB.

Some Hyundai vehicles may be equipped with a parking distance warning (PDW) sensor(s) that may trigger various DTCs and display warning messages on the instrument cluster, resulting in the PDW sensor(s) failing to detect nearby objects or triggering multiple false alarms. This condition may be a result of external damage to the PDW sensor membrane or sensor cover from rock chips or road debris, a collision, or previous vehicle repairs or modifications.

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 Elantra (CN7), Elantra Hybrid (CN7 HEV), and Elantra N (CN7 N) vehicles may exhibit loose windshield side garnishes. This bulletin provides instructions to replace the windshield side garnishes with improved parts to correct the condition.

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.
