2022 Hyundai Elantra Electrical Problems

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 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 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 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 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 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 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.

Back camera stopped working

Horn stopped working after 10,000 miles. Unable to alert other drivers in case of an emergency situation

Car horn failure. Almost had an accident. Tried to honk the horn, so that i could warn the other driver coming toward my lane, nothing, no sound at all. I swerved my car out of the way... it could have been bad if there was a car next to me. Took the car to the dealership. Verdict, they said the car horn needs to be changed. Nope, did not notice any warnings that the horn gonna malfunction. It is messed up. I hardly use the horn and yet it is broken. Isn't the horn supposed to last a while?
