Known issues on the 2021 Accent. Three recalls are on federal record for this model year. The first covers the front seat belts: in a crash, the driver-side or passenger-side seat belt pretensioner may explode when it deploys, projecting metal fragments into the vehicle. The second covers the steering column, where a bolt may not have been secured properly, which can cause the column to detach — a loss of steering control that increases the risk of a crash. The third covers the brake master cylinder, which may have been manufactured with sharp edges that can damage the inner oil seal; the resulting reduced braking performance can cause longer brake pedal travel. Owners have filed 22 complaints for the year and Hyundai has issued 49 technical service bulletins. The factory diagnostic and repair procedures behind each of those systems are in this manual.
From checking a seat belt pretensioner after deployment to torquing the steering column hardware or bleeding the hydraulics after a master cylinder replacement, it keeps the work on Hyundai's own procedure and specification for your 2021 Accent.

The car seems to have sort of an alignment problem. Steering keeps going to the left and I constantly have to pull steering to the right. Even with both have on steering wheel the car goes to the left lane. If I make a left turn the steering seems to want to stay to the left and I get the feeling the car is going to flip over. It's like there is a gap in the steering wheel. A miscommunication between the steering and front axle kind of. They tried to fix it three times without any success, and n

The studs and the lug nuts have consistently cross-threading and corrosion issues in a barely-year-old vehicle. I have had to visit the dealer twice to have this problem fixed and paid out of pocket. This started to happen ever since my last service at a Hyundai dealership. I suspect that this is because of low quality or defective lugnuts/studs that are being used, which is causing the lugnuts to be stuck and break off while trying to remove them. 2 of the lugnuts and studs in the vehicle had t

I've been trying for about 6 months to get this recall corrected. I've called several dealers and no one has the parts. Isn't it ridiculous that they are suggesting I park the car outside my garage because it is dangerous to park it inside, BUT it's OK if I drive it???? When will these parts be available?

During a tire swap, another lug nut broke off while trying to remove it. This issue has occurred before, and it seems that the faulty lug nut problem is still present. The car has only been serviced at Hyundai dealerships, and the tires were last rotated during a service at an authorized Hyundai dealership before this incident. The affected lug nut this time was on the front passenger side.
