Hyundai Elantra N Reliability by YearBest & worst years, problems & recalls — NHTSA data

When vehicle gets wet, knock sensor trips and puts the vehicle in limp mode. Making it very dangerous to drive since everything is underpowered and makes it hard to get up to speed, shift, etc.

The contact owns a 2023 Hyundai Elantra N. The contact received notification of NHTSA Campaign Number: (AWAITING); Manufacturer Recall Number: 262 (Fuel System, Gasoline) however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the failure. The contact had not experienced a failure. VIN tool confirms parts not available.

This is a known issue within these new Hyundai N cars and Hyundai is completely clueless. It’s a “p1326 code” that pops up after a carwash. Whenever the knock sensor gets wet it automatically puts the car into limp mode at highway speeds and it’s very hazardous. There has to be some type of cover that Hyundai has to put over the knock sensor or this will continue to happen to us while it’s a brand new car.

While driving through heavy rain on the interstate Friday night the CEL came on and the vehicle immediately lost power and went I to a limo mode causing my car to rapidly lose speed while on the interstate. Restarting the vehicle did nothing. I called the closest Hyundai dealer and they said " oh yeah the N models do that a lot in the rain or through carwashes, it triggers false knock sensor codes, you can try to get a parts store to clear the code or you can come in tomorrow and we will clear the code." I then got a parts store to clear the code and the vehicle has been fine since. I did a quick internet search and apparently this is very common and lots of owners have this happened multiple times a year and the dealer has no fix or intention of a fix

Hit a shallow pothole at or around 40-55 miles/hour. Estimate. Strut mount broke. Hit a shallow pot hole and strut mount broke and pulled car to the right. Safety issue for 18 year old driver. Dealer refused to receive vehicle and investigate. Said it was an insurance issue. Insurance inspected car. Adjuster said he has never seen a new car break strut mount. Car bottom graphics and underneath not damaged. Rust was on the brand new strut mount welds. Body shop advises that was reason of failure, rust on welds. Not right for a pothole to break strut and end up totaling out a brand new $38,000 car. Not right that insurance is responsible to pay for it and Hyundai would not even look at vehicle.

Hello. While driving my 2023 Elantra N, innthe middle of driving, it set a flashing check engine light. During this event, my car started sputtering in between shifts and would not climb over 2500 rounds per minute. During this event I was driving 70 miles per hour on the highway, causing me to almost get rear ended. The check engine light is flashing but is consitently set. The code that's causing the check engine light is P132600. After doing my own personal research in Elantra N forums, this has been a common fault among many Elantra N models. Hyundai has made no official recall for it yet.

This problem occurred in my previous vehicle which was a 2022 Hyundai Kona N. I took it through a car wash and had a check engine light turn on. The car went into limp mode and I had it towed to the dealership. The check engine light was a code from the knock sensor. Hyundai replaced the engine when the vehicle only had 5,200 miles on it. I have since traded that vehicle for a 2023 Hyundai Elantra N. Upon doing some research, it is a very common issue with the N trims of Kona's and Elantra's to throw a check engine light due to heavy rain or car washes. Sometimes this results in an engine replacement, other times just resetting the code. This issue needs corrected. So far, Hyundai has practically ignored me on this. I have sent in multiple screenshots of the same issues that others have been facing. When this check engine light comes on, the vehicle goes into limp mode which is very dangerous if traveling at highway speeds.

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.
