2017 Hyundai Accent Complaints

ENGINE — Filed 06/20/2026

I have replaced the GDI engine on the 2017 Hyundai Accent once. I have also had the catalytic converter replaced 3x. The car lunges as if there will be another catalytic converter issue soon. Hyuandi recommended a fuel induction completion to prevent the issue from occurring again, but it did. This is a safety issue because the car and stall out at any given time. The cause of this issue has yet to be detected. It is believe a recall is needed on the GDI engine and catalytic converter.

While traveling on a public roadway under wet conditions, the vehicle was unable to stop within a safe distance despite brake application, resulting in a rear-end collision with the vehicle ahead. The primary concern is that the airbags did not deploy during the impact, despite significant front-end damage. The collision caused severe deformation of the hood and extensive damage to the front-left area, including the fender, bumper, and headlight assembly, with visible intrusion into the engine compartment. The vehicle was subsequently determined to be a total loss, which raises concerns about whether the airbag system functioned as intended under these impact conditions. Prior to the incident, there were no warning lights, dashboard messages, or other indications of a malfunction. The issue has not been reproduced or evaluated by a dealer or independent service center due to the extent of the damage. The incident was documented by responding law enforcement, and the vehicle has been reported to an insurance carrier. The failure of the airbags to deploy in a collision resulting in severe front-end damage may have increased the risk of injury to the driver. The vehicle is no longer available for inspection.

I have had this vehicle for 5 years and even replaced the engine in this vehicle for it to end up with the same issue. I take very good care of it and get its maintenance done. But the car is slow to get up to speed and misfires really bad. I replaced the spark plugs in it and they were coated in oil. The airbag sensor will come on indicating it’s not operating properly. Overall a very unreliable vehicle that has multiple issues. It has ended in catastrophic engine failure twice now

On [XXX] driving home from Crestline to Covina. My car died to get onto the on ramp at the [XXX] I had to pull over to a side street. My brakes weren’t working no indication light came on. I had it towed to Fontana Hyundai where they did a diagnostic And said my catalytic converter was the problem they had one in stock they replaced it sidenote, I had an oil change the week before. I took the car home. I drove back to Crestline on Monday. My family was with me. My car was throwing smoke on acceleration. I took it back to the dealer. I left it the next day I had no phone call despite sending a text and a phone call message with no response. I picked up the car the following day at three. I was told they drove it and they had no problems And that the problem was my fault basically. I was told I needed a new engine. They didn’t know when it would happen. I filed a complaint with Hyundai. I requested a Goodwill request and was just informed today. It was denied due to not enough maintenance records. I had the oil changed regularly on that car. I had no prior problems with the engine. I am left now without a car and a $2500 bill and still no car and I’d like to know if there’s any action I can take moving forward. I did not get a phone call to say that my Goodwill claim was denied. It was just an email. Thank you in advance, Laura. I have more oil change receipts here. I also lived in the inland Empire for a while, and probably have more in those cities, but I don’t know where I got the oil changes and I didn’t have copies in my car. They denied my claim because I didn’t have enough maintenance records although I maintained the car and their catalytic converter broke my engine and I have no car now. We’d I took my car to Sako’s auto. He checked my oil. I had no oil in the engine and that was after my catalytic converter was repaired. My car is broken. They won’t fix it. I need to know what to do. I am not happy with this decision. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

To preference, I have only owned this vehicle for less than six months, and that the only major issue concerning the vehicle was the replacement of the catalytic converter manifold. On the afternoon of [XXX] I was coming to a complete stop at a very busy 4-way located in Peach County, GA when the power to the entire vehicle was shut down. There was difficulty attempting to turn over the key in ignition, so with the help from a passerby I was able to push my vehicle to a safe location nearby as my vehicle was idle in the middle of a populated 4-way intersection, putting my and others’ safety at risk. As I go to check under the hood, I look for any components out of place and to check fluids. I check my oil dipstick to notice that there was metal residue in my oil, something that was not present previous to my commute in the area. As I am now able to turn over the ignition, a sputtering noise begins to emit from the engine, a noise that was also not present previous to my commute. Within the hour I was able to move my car, albeit slowly to a U-Haul location; it should also be known that my check engine light appeared in the process (no warning lamps were present on the vehicle prior to the engine failure). I returned home and instantly got in contact with my technician who does repairs to my car and he confirmed after inspecting the oil and noise from the engine that it was engine failure and that there may have been a ‘recall on the engine’ as did another mechanic I advised with. I called my local dealership about any recalls on my vehicle to which they said no, I then called the customer service hotline to begin a claim on my vehicle: I asked questions in relations to warranty, the previous owner, service history that may have went undocumented all with it being that the conclusion from the operator was that the warranty that was attached to the vehicle was expired and that it would not have covered the repair of the engine anyway.

I had two different mechanics I trust tell me that this car has a particular engine that had an error in manufacturing, but Hyundai didn't correct it, because it would cost them too much. The error is heavy oil burning, such that it destroys the catalytic converter. I am now on my third catalytic converter in this car, and the check-engine light is beginning to flicker. Mechanic recommended contacting Hyundai corporate to file a complaint. He knows of others with this same engine, and dealers in New Hampshire have been able to get new engine replacements. I tried to call Hyundai corporate, but they refuse to take any information from me and tell me I would have to buy a new engine if I want to replace it. Mechanics have said that the cost would be heavy for Hyundai if they admitted the problem. But they must be aware of the problem, since they have replaced some engines for people who have the time and money to chase them around. The problem developed well before the 100,000 mile warrantee expired. The car is now over that limit, but the issue was first reported before that limit was reached.

My catalytic converter failed on my car and will eventually needed a new engine. I was driving a busy road doing about 55 miles per hour and my car suddenly dropped down to 3-5 miles per hour without warning now flashing light on the dash nothing. I could have been killed or hit causing a multi car accident. I was so scared and it was so hot I thought my engine was going to blow. I coasted back into the auto place that just preformed my oil change thinking they had done something wrong. They did a throughall diagnostic of my car and my car was read that my catalytic converter was bad. So I then got my car to the Pearson Hyundai dealership where there formally diagnosed my car stating that I needed to replace my catalytic converter for 2500 - 3000, but I had done my research and new it was a known problem. People in several Hyundai Forums have been complaining about this same issue. I asked for assistance in getting my car repaired from Pearson Hyundai, Hyundai USA, and I even wrote a letter to the CEO of Hyundai to no avail. I have been without my car since June. Hyundai has a real issue with oil consumption, bad catalytic converters and they need to replace my engine warranty or not. I feel my vehicle is very unsafe and I am nervous to drive it. I can't drive it if I wanted to more then a few feet because it chokes up and the goes 3-5 miles per hour feel like it is going to die at any moment. I am asking that Hyundai take ownership of it's faulty car parts and do the right thing by its consumers. Anything could have happened to me in that day in June and it seems nobody is worried about it. Hyundai can not just pick and chose who gets a replacements when other models are having the same issue. There were no prior warning lights or signs other than the error code that the auto place provided.

I have already submitted a report here and never had any follow up and I don't see it in the reported complaints section of this website with newer incidents already showing so I know it isn't that there is a back log. my car caught on fire while I was in the car, asleep. I have reports from the fire department, I have struggled with Hyundai for months and ultimately was denied any assistance due to I was missing one of two service records. the fire report clearly stated that fire started in the cabin of the car not the engine so a lack of an oil change shouldn't have been the reason this happened. this event has traumatized me and continues to be an enormous burden on me and my family and their lack of caring is beyond disheartening. I easily could have died that day, by all accounts I should have. I would greatly appreciate some sort of follow-up as I feel like I'm just being completely ignored and discredited. I would gladly provide more information as to the actual incident if needed but like I said I have already done so in another report and don't want to do it again if it's just going to be ignored a second time.
