Dealing with transmission problems in your Hyundai Elantra? You might be affected by one of several recalls or be experiencing issues that are part of ongoing legal action. This guide breaks down everything about the Hyundai Elantra transmission recall situation – what’s happening, which models are affected, and what you can do about it right now.
The Transmission Types Causing Problems
Hyundai Elantra models have experienced issues with several transmission types, each with their own specific problems and recalls.
Intelligent Variable Transmission (IVT) Issues
The IVT is Hyundai’s version of a continuously variable transmission but uses a chain-based system instead of the traditional belt-and-pulley design found in most CVTs. According to multiple owner reports, this system has experienced significant reliability problems, particularly in 2020 and newer models.
Common IVT problems include:
- Sudden loss of acceleration while driving
- Vehicle not responding when pressing the gas pedal
- Transmission feeling “disengaged”
- Complete transmission failure at relatively low mileage
Despite widespread issues, Hyundai hasn’t issued a full recall specifically for IVT reliability problems, leading to a class action lawsuit filed in September 2024.
Dual-Clutch Transmission (DCT) Recall
The 8-speed wet dual-clutch transmission used in the Elantra N and other performance models has been subject to a major recall affecting over 53,000 vehicles. The recall (NHTSA Campaign Number 22V746000) addressed a high-pressure oil pump malfunction that could cause complete loss of drive power after 20-30 seconds.
This issue primarily affected vehicles produced between September 15, 2021, and April 8, 2022. The fix involves updating the Transmission Control Unit software and possibly replacing the entire transmission if specific diagnostic trouble codes are present.
Hybrid System Transmission Problems
The Elantra Hybrid models from 2021-2023 faced a unique issue with the Motor Control Unit (MCU) that could cause unintended acceleration after releasing the brake pedal. This recall (NHTSA Campaign Number 23V589000) affected nearly 38,000 vehicles and required a software update to fix the problem.

This recall addressed a “fail-safe” condition in the hybrid system that temporarily results in slow, unintended acceleration after releasing the brake pedal. According to NHTSA documentation, the service brake functionality remained fully operational, and the fix involved updating the MCU software logic.
The Ongoing Class Action Lawsuit
In September 2024, a significant class action lawsuit was filed by Patricia Donadio in California federal court. The lawsuit targets IVT transmission reliability issues across multiple Hyundai models including:
- 2020 or newer Elantra
- 2020 or newer Accent
- 2022 or newer Kona
- 2020 or newer Venue
The lawsuit alleges that despite numerous complaints and documented problems, Hyundai has failed to issue a recall for these persistent IVT issues. Many owners report that dealerships have been unable to provide permanent fixes for the problems.
Technical Service Bulletins and Oil Pressure Sensor Issues
Beyond the official recalls, Hyundai has issued several Technical Service Bulletins (TSBs) addressing transmission-related issues. A notable 2023 bulletin (TSB 23-AT-010H) addressed oil pressure sensor failures in IVT-equipped vehicles.
This bulletin covered specific diagnostic trouble codes (P0845, P0846, P0867) and provided guidance on replacing just the oil pressure sensor rather than the entire transmission. According to the documentation, this repair is only recommended when no drivability concerns are present.
Real-World Owner Experiences
Owner reports consistently describe significant reliability issues with IVT transmissions, particularly in 2020 model year vehicles. Common complaints include:
| Common IVT Problems | Typical Symptoms |
|---|---|
| Transmission slipping | Jerky acceleration, inconsistent power delivery |
| Poor acceleration response | Delayed response when pressing the gas pedal |
| Unusual noises | Droning, whining, or grinding sounds |
| Complete transmission failure | Total loss of drive power, requiring replacement |
One documented case involved a 2020 Elantra requiring complete transmission replacement at only 89,000 miles. The owner faced warranty coverage disputes due to being a second owner, highlighting an important warranty limitation many owners aren’t aware of.
Warranty Considerations You Need to Know
A critical detail many Hyundai owners don’t realize: the powertrain warranty coverage (including transmission) is typically reduced for second and subsequent owners. While Hyundai advertises a 10-year/100,000-mile powertrain warranty, it may be limited to just 5-year/60,000-miles for anyone who isn’t the original owner.
This warranty reduction has been a source of significant frustration for many owners facing expensive transmission repairs. According to owner forums, transmission replacements can cost $5,000-$7,000 when not covered under warranty.
What Owners Should Do Now
If you own a Hyundai Elantra with any of the transmission types mentioned above, here are the immediate steps you should take:
1. Check Your VIN for Recalls
Use the NHTSA’s recall lookup tool or Hyundai’s recall website to enter your Vehicle Identification Number (VIN) and check for any open recalls. If your vehicle has an open recall, contact your dealer immediately to schedule the necessary repairs at no cost to you.
2. Monitor for Symptoms
Be alert for any signs of transmission problems, including:
- Check engine light illumination
- Unusual transmission behavior (jerking, slipping, delayed response)
- Warning messages on your dashboard
- Loss of power while driving
3. Document Everything
If you experience any transmission issues:
- Note the date, time, and conditions when problems occur
- Save all service records and repair invoices

Don’t ignore these warning signs – addressing transmission issues early can sometimes prevent complete failure and more expensive repairs.
How Hyundai Dealers Are Handling Transmission Issues
Owner experiences with dealers have varied widely when it comes to transmission issues. Some key patterns have emerged:
- Many dealers initially attempt software updates rather than transmission replacement
- Some owners report multiple repair attempts before complete transmission replacement
- Warranty coverage disputes are common, especially for subsequent owners
- Service departments often cite “normal operation” for IVT characteristics that owners find problematic
To get the best dealer service, be specific about the symptoms you’re experiencing, reference any applicable recalls or technical service bulletins, and escalate to service managers or Hyundai corporate if necessary.
The Technical Side: Understanding Hyundai’s Transmission Systems
IVT Technology
Hyundai’s Intelligent Variable Transmission uses a chain-based system instead of the belt-and-pulley setup found in traditional CVTs. This design was intended to improve durability and provide a more direct driving feel compared to conventional CVTs. Unfortunately, real-world experience has shown numerous reliability issues.
The IVT works by continuously varying the effective gear ratio using a chain that moves between variable-width pulleys. This provides theoretically infinite gear ratios for optimal efficiency, but the complex electronics and hydraulics controlling this system have been prone to failure.
Dual-Clutch Transmission Details
The 8-speed wet dual-clutch transmission used in the Elantra N features two separate clutches – one for odd-numbered gears and one for even-numbered gears. This allows for extremely fast shifts as one clutch engages while the other disengages.
The “wet” designation means the clutches operate in an oil bath for cooling and lubrication, which is particularly important for high-performance applications. The oil pump that circulates this fluid has been the source of the major recall affecting these transmissions.
International Perspective on Hyundai Transmission Issues
Transmission problems with Hyundai vehicles aren’t limited to the United States. Similar issues have been reported in Canada, Australia, and Europe, though the specific recall actions have varied by region.
In some markets, Hyundai has provided more extensive warranty coverage or goodwill repairs for transmission issues, particularly in regions with stronger consumer protection laws. This global pattern suggests the problems are inherent to the transmission designs rather than market-specific issues.
Conclusion: Protecting Yourself as an Elantra Owner
If you own a Hyundai Elantra with one of the affected transmissions, staying informed and proactive is your best defense. Check for recalls regularly, maintain detailed documentation of any issues, and don’t hesitate to seek repairs at the first sign of trouble.
For those considering a new or used Elantra purchase, thoroughly research the specific transmission in the model you’re considering and factor potential repair costs into your decision-making process. The ongoing lawsuit may eventually result in additional consumer protections, but for now, educated vigilance is your best strategy.
