2024 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.

VERY DANGEROUS when you have NO HORN!!! Pls look into WHY the horn keeps randomly going out about every 12,000 miles I need a new horn!!!!Owner complaint, filed 2026

The vehicle has less than 2,000 miles on it being a 2024 model (hybrid limited) and on more than 2 occasions without warning the car will be dead while parked. No accessories left plugged in to cause drainage, no warning from the MyHyundai bluelink app, and the dealers are completely clueless. The vehicle gets driven every day, and in…Owner complaint, filed 2025

Parts named most: Warnings (6), Automatic emergency braking (5).

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.

This happens frequently and has probably happened at least 6 or 7 times since I purchased the car last month. Digital warning alert appears on dash for no reason saying “Consider Taking a Break” even though i consistently keep my car in my lane. The warning is both distracting and annoying, and there is no way on this vehicle to turn it…Owner complaint, filed 2025

I randomly get warning lights that my camera is disabled for Lane Departure Warning, Blind Spot Warning, Forward Collision warning, Lane Assist Warning. Each warning message I get comes one after the other stating CAMERA disabled. After a few minutes of driving, all the orange lights disappear and it seems to reset itself to normal. This…Owner complaint, filed 2025

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.

What to check before you buy

• Turn the wheel lock to lock while parked and listen for groaning, clicking or binding.
• On a straight road the car should track straight with the wheel centered and no loose feeling.
• A power steering warning on the dash, even briefly, deserves a mechanic’s look before you buy.

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.

My 2024 Hyundai Elantra limited keep slamming the breaks and Hyundai keep running me in circles and won’t fix it. I fear my vehicle will cause a collision. A case with Hyundai has been open for over 3 months.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

• Read the four-digit DOT date on each tire. Tires older than about six years should be replaced, whatever the tread looks like.
• Check tread depth on all four. On AWD vehicles all four tires should match.
• The tire pressure light should go out after startup.

What to check before you buy

• 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.

What to check before you buy

• Smell around the engine bay and under the rear of the car for raw fuel.
• On the test drive, accelerate firmly from a stop and up a grade. Stumbling, surging or a flashing check engine light are red flags.
• Fuel pump recalls are common. Check this exact VIN for open recalls before you buy.

When you accelerate & let off the gas pedal, the vehicle still accelerated for 2 seconds after you release the gas pedal. It is like there is a delay with drive by wire signal. This situation can cause rear end collisions & hard panic braking. Please recall this situation to prevent higher insurance cost & increased accidents!Owner complaint, filed 2025

What to check before you buy

• The air bag (SRS) light should come on at startup and go out within a few seconds. If it stays on, the system may not work in a crash.
• Air bag recalls are some of the most serious. Check this exact VIN for open recalls and get proof any recall work was done.
