Source: NHTSA, updated daily. Last checked 2026-10-18. Recalls apply to specific VINs — run your VIN to confirm.
1 safety recall, most serious first
1. Latches / locks
What's wrong, in plain English: Doors, hood or trunk may open unexpectedly. The trunk latch may become damaged, preventing the opening of the trunk from the inside. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 401, "Internal Trunk Release."
What could happen: A person inside the trunk compartment may become trapped, increasing their risk of injury.
The fix: Dealers will replace the trunk latch base, free of charge. Owner notification letters were mailed December 4, 2021. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 208.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2018 SONATA.
- Book a repair at any authorized Hyundai dealer. Quote NHTSA campaign 21V619000 (manufacturer code 208).
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-855-371-9460.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.

What component or system failed or malfunctioned, and is it available for inspection upon request? The paint is peeling off the car, when I went to the dealership they said this is a known problem for 2015-2018, but they can't fix it there is no recall. It is causing rust. The valve cover gasket leaks oil and caused spark plugs to blow twice. How was your…

Hyundai dealership confirms I am in need of a new engine due to large oil consumption which is a known issue on 2018 Hyundai Sonata engines. Hyundai will not approve repairs because I am the second owner and vehicle is out of the 5 year warranty period. I only have 52K miles on my vehicle.

Since I had Service Campaign 9C2 completed, the car hesitates to start, does a mini-lurch upon cold start and runs rough. Two weeks ago, it was put in park, lurched backwards, then died. The starter and battery have been replaced but this has not helped. The car ran fine before this update was done.

I recently had the 9C2 Emissions recall update performed on my car, and since the update my car drives like total garbage after a cold start. It hesitates to accelerate, it bucks when trying to accelerate, and it’s to the point the engine is about to stall. I took it back to the Hyundai dealership and they said they are aware of the issue, but there is no f…

The paint on all parts of the car is completely coming off down to bare metal. It’s as if the car wasn’t prepped to receive paint. Every Hyundai I pass that’s white the paint is coming off. There is also an internal engine oil leak where I’m losing 4qts of oil a week.
