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…

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…

Faulty light switch that causes headlights to go on and off at night. Sometimes headlights will shut off completely and not come back on or vise versa staying on and draining the battery. Faulty switch cause complete loss of headlight control. Numerous others have reported the same issue online across all elantras in a certain year range as well as other models.

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.

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…

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.

The subframe is pressed against the hard brake line. Hyundai is denying warranty claim saying this couldn’t have happened from factory, yet the subframe hasn’t ever been removed and there no evidence of it.
