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.

My 2021 Hyundai accent has randomly not started a in more than 10 different times. The lights go on and you can hear it trying to start but it never catches to actually start. It’s under warranty but the dealer says if they can’t see it when it’s happening then they can’t fix anything. I bought a new battery with dealer recommendations but I still hace they problem. I only have 25,300 miles on this 2 year old car.

Fifth lug nut failure within a span of less than 6 months. Today during winter to summer tire snow change, front passenger side lug nut broke while it was being removed. This is the 4th incident in my vehicle with regards to the lug nuts. Less than two weeks ago, during routine maintenance at a Hyundai dealership, another lugnut broke and I have also registered a complaint here.

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 to be broken off to be removed last week (11/28/22). Yesterday (12/04/2022) during a tire change, another lugnut/stud broke off during removal. Hyundai should look into this faulty lugnuts/stud problem and have it resolved.

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?

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 now they are ignoring me, they don't answer my calls. I only drive it to work because I have to. The dealer says it's not that bad. Well maybe it's not that bad to drive it around the block but to drive it one hour everyday is a problem for me, even my right hand and arm start to hurt after half hour of constant dragging. Dealer told me all there accents drive the same. Well for me it means they all have same problem probably. Mechanics told me they get lot of cars with same problem. I am sure they are aware of it. I even took a video while driving to demonstrate defect and definitely it's not safe to drive. They tried to align the car three times at two different dealers with no success. Dealers repair files attached.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Hyundai Accent 5 verdict →
