2025 Hyundai Sonata — Known Issues & Recalls

While driving home, you heard a loud noise like a gunshot and discovered your moonroof glass had suddenly shattered or exploded. You've documented the damage with photos and video, and found online reports of similar incidents in other Hyundai vehicles dating back to 2011. You're waiting to contact the dealership service department on Monday to pursue a warranty repair.

Your speedometer reading doesn't match your actual speed. When your passenger timed your car between mile markers, the distance traveled didn't match what the speedometer showed. This could mean your speedometer is giving you incorrect speed information.

Your gas tank is loose and was discovered to be moving when you were pumping gas. This issue was identified at the Red McCombs dealership, which is the only service facility that has worked on your vehicle so far. The dealership will need to inspect and secure the tank to its mounting points.

After filling up your gas tank or refueling, you notice a strong gasoline smell inside the cabin that lingers for a while. This happens consistently when you top off the tank to full.

After a dealer visit for a radio software update, you noticed your speedometer no longer matches your actual speed. You're concerned because another 2025 Sonata owner reported the same issue in December 2024, and you suspect the speedometer was updated during your service. This means your speed readings could be inaccurate, which affects your ability to know how fast you're actually driving.

Your speedometer display is showing inaccurate readings, sometimes displaying 1-4 mph higher than your actual speed and other times 6-8 mph higher. You've verified this inconsistency using multiple sources including another vehicle's sonar system, street speed limit signs, and your own GPS. The fix will likely involve recalibrating the speedometer sensor or replacing the instrument cluster.

Your 2025 Sonata squeals when you release the brake pedal after stopping or when shifting from braking to acceleration, even though the car has fewer than 4,000 miles and brake pads should be essentially new. This noise happens consistently and hasn't gone away on its own. The issue may be caused by a manufacturing defect, defective brake pad material, or a brake caliper that isn't fully releasing after you brake. The fix will likely involve inspecting and possibly replacing the brake pads, rotors, or brake calipers to restore normal brake operation and eliminate the noise.

Your brake pedal sits noticeably higher than the gas pedal, requiring extra foot movement to reach it during normal driving. You're concerned this higher position may slow your reaction time in emergency braking situations. The dealership hasn't confirmed whether this is normal or if adjustments are available.

Your check engine light came on, along with an airflow notification and a brake system warning message. These warnings suggest potential issues with your engine, air intake system, and brakes that should be diagnosed by a mechanic. The fix will likely involve computer diagnostic scanning to identify the specific fault codes and then addressing the underlying problems.

Your car vibrates or shakes when you're driving on the highway at higher speeds. This is typically caused by wheel balance issues, tire problems, or suspension alignment concerns. A mechanic can diagnose the exact cause through wheel balancing, tire inspection, and wheel alignment checks.
