2022 Hyundai Elantra — Known Issues & Recalls

Your vehicle's forward collision avoidance and radar-based safety systems are disabling themselves and showing a "Check Forward Safety System" warning. This happens because the front radar becomes misaligned, which also causes your infotainment screen to go blank. When this occurs, you lose critical safety features like Forward Collision-Avoidance Assist and Smart Cruise Control, meaning you won't get alerts about potential front-end collisions. The fix typically involves having the front radar recalibrated or replaced, though some owners report the problem returns a few months later and requires another repair.

Your Forward Safety System warning light has been staying on for about 6 months, though it turned off and on repeatedly before that. The dealership estimates it will take a week or two of labor to diagnose and repair, which is costly given you purchased the car new. The fix will likely involve diagnosing the forward collision avoidance system's sensors or wiring to identify why the warning light remains illuminated.

Your car's forward collision avoidance system displays an error message whenever you try to use the cruise control button. This prevents you from using the cruise control feature. The issue may require a diagnostic scan of the safety system and potentially software updates or sensor recalibration.

Your car's horn isn't working, which prevented you from warning another driver of your presence when they nearly backed into you. You discovered online that many other Hyundai owners have reported the same faulty horn problem. The horn should be inspected and repaired at the dealer to restore this important safety feature.

Your car's display screen goes black and stops showing the GPS navigation system. The screen becomes completely unresponsive during use. This may require the display unit to be reprogrammed or replaced to restore functionality.

Your horn has failed and needed replacement for the second time in a year. The dealership reports this is a widespread issue, with multiple horns failing across several vehicles. The repair involves replacing the faulty horn unit with a new one.

Your parked 2022 Hyundai Elantra caught fire without warning while unoccupied, with no warning lights appearing beforehand. The vehicle had only been parked for five minutes before the fire started. The fire department extinguished the fire, and the vehicle was towed for inspection—the manufacturer has been notified and a case was filed. The issue likely involves an engine or electrical component failure that caused the fire, which will require a dealer inspection and potential component replacement or repair.

While driving at 63 MPH, your Elantra displayed multiple warning lights and showed a message that the vehicle was in neutral, forcing you to pull over. The dealer diagnosed a complete engine failure at 34,000 miles and said the engine needs to be replaced. Hyundai has not offered assistance or taken responsibility for the issue. Replacing the engine is a major repair that typically involves removing the failed engine and installing a new or rebuilt unit.

While you were slowly pulling into a parking spot, your car suddenly accelerated without warning, even though you were applying the brakes. The car crashed into a PVC fence, but fortunately no one was injured. You haven't had the car inspected yet to determine whether the issue was with the brakes, accelerator, or another system. A full diagnostic inspection at a dealership or mechanic would be needed to identify what caused the unexpected acceleration.

Mice are getting into the front of your car, leaving urine smell and nests in the air filter area. You're finding debris and dead mice when you clean the filters monthly, and the smell makes the cabin unsafe to breathe. The issue appears to be a design flaw with this model that hasn't been addressed by the manufacturer. Fixing this likely requires sealing entry points around the engine bay and possibly installing rodent deterrents or barriers.

Your vehicle's brakes and emergency brake failed completely without warning, causing you to lose the ability to stop and resulting in a collision. The dealership inspection found no issues and couldn't reproduce the problem, but you discovered technical service bulletins from Hyundai describing the exact brake failure symptoms you experienced. The dealership did not inform you of these known issues or apply the recommended fixes, leaving the safety problem potentially unresolved.

Your horn has stopped working, which concerns you for safety while driving. Your car's right-side suspension is making excessive rattling noises, and your air conditioning is blowing hot air instead of cool air. These issues will likely require diagnosis and repair of the horn circuit, suspension components, and AC system respectively.

Your 2022 Hyundai N Line had an oil seal left out during an oil change at about 17,000 miles, causing rapid oil loss on the highway. This led to a catalytic converter fault code (P0420), and Hyundai replaced the converter under warranty but refused to provide diagnostic details. After the repair, your car developed new hesitation during acceleration that wasn't there before, suggesting the warranty work may not have fully resolved the underlying problem or caused additional issues.

Your headlights are turning off and on randomly during both day and night driving, which creates a safety hazard when driving at night in rural areas. The dealer has been unable to reproduce the issue during two service visits, though you've documented the problem occurring daily with daytime photos. The fix will likely involve diagnosing the headlight electrical circuit, which may require a wiring harness inspection or replacement of faulty headlight control modules.

Your car is displaying a 'Check Forward Safety System' warning message, and your cruise control has stopped working as a result. This warning appeared without any accident or collision occurring. This is a safety feature issue that may require diagnosis and repair by Hyundai.

Your rearview camera doesn't show a clear image or shows nothing when you shift into reverse. Other 2021 and 2022 Elantra sedans were recalled for this issue (Recall #271), but Hyundai says your vehicle isn't eligible for the recall repair. The fix will likely involve replacing or reprogramming the rearview camera module.

Your car's traction control and stability control systems are randomly activating while you're driving, causing the car to jerk to the right and the brake pedal to shake. You'll hear a loud noise and see the warning light flash for a few seconds before everything returns to normal, though the problem happens repeatedly over short periods of time. Your dealer couldn't find any error codes to help diagnose the issue. The fix will likely involve a brake system inspection, wheel speed sensor check, or electronic stability control module diagnosis once the problem can be reproduced.

Your car's horn doesn't work. This is a safety concern since you won't be able to alert other drivers in an emergency situation. The fix will likely involve checking the horn's electrical connections, testing the horn relay, or replacing the horn unit itself.

Your air conditioner evaporator has failed at 62,000 miles, causing your AC to blow hot air and making unusual noises. The dealership confirmed this is a known issue with your model. You'll need to have the evaporator replaced, which involves removing the dashboard to access the component inside your vehicle's HVAC system.

Your rear view camera has stopped working, which makes it harder to see when you're backing up. You checked for recalls using your VIN number but none are currently available for your car. You believe this may be the same issue covered under recall campaign 24V879000, but your vehicle isn't included in that recall.
