2023 Hyundai Elantra Problems

What to check before you buy

• Test every switch: windows, locks, mirrors, seat heaters, the screen, the backup camera, Bluetooth and every USB port.
• Watch the dash at startup. Every warning light should come on briefly and then go out.
• Have the battery and charging system tested. A weak alternator or battery drain shows up here.

I have a 2023 Hyundal Elantra SEL and my rear camera starts flickering and also goes blank frequently. In fact nowadays it is rarely working. I understand that there was a recall for 2021 and 2022 but not for 2023 yet. However it seems the issue continues with 2023 as well cause when I google I see I am not the only one having this…Owner complaint, filed 2026

Horn is inoperable due to internal fault. Horn receives power when button is depressed, relay actuates, but horn does not sound. There is no warning system in place for this fault.Owner complaint, filed 2025

Parts named most: Automatic emergency braking (14), Warnings (9).

What to check before you buy

• Where it is safe, try the adaptive cruise and lane keeping on the test drive and watch for sudden braking or warnings with nothing there.
• Check the windshield in front of the camera and the bumper sensors for cracks, chips or poor repairs.
• Ask whether the windshield has been replaced. The camera has to be recalibrated afterward, and many shops skip it.

What to check before you buy

• Ask the seller not to warm the car up, and start it cold. Listen for ticking, knocking or a rough idle in the first minute.
• Pull the oil dipstick and the oil cap. Low oil, a gasoline smell or a milky film on the cap are reasons to walk away or get an inspection.
• Plug in an OBD2 scanner. Stored or pending codes matter, and so do readiness monitors that show "not ready", which usually means the codes were cleared right before the sale.
• Ask for oil change records. A gap in the records on a model known for engine complaints is a negotiating point at minimum.

The engine mounts on this vehicle failed. Dealership and many others online have stated that this seems to be a reoccurring issue with the 2021-2023 generation of Hyundai elantras. The vibrations of these failed motor mounts become so severe that they can dislodge the brakes making it very unsafe to drive. Hyundai should be doing a…Owner complaint, filed 2026

What to check before you buy

• Drive it from cold if you can. Shifts should be smooth in every gear, including reverse.
• Feel for slipping (revs rise without the car speeding up), shudder at low speed and a delay when you put it in gear.
• Listen for whining, which is a common CVT complaint, and clunks when you go from drive to reverse.
• If it has 4WD or AWD, engage it on the test drive and ask when the transmission and differential fluids were last changed.

What to check before you buy

• The pedal should feel firm and the car should stop straight without pulling, grinding or a pulsing pedal.
• The ABS and stability control lights should go out after startup and stay out.
• Look through the wheels at the rotors. A deep lip on the edge means brakes are due soon, which is a fair thing to negotiate on.

• Look underneath with a flashlight. Utah road salt is hard on frames, brake lines and the bottoms of doors.
• Open and close every door, the hood and the liftgate, and lock and unlock each one.
• Use a paint thickness gauge and compare panels. A panel that reads very differently from the rest has likely been repaired.
