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 purchased my car in February I was told everything was fine, my car does this jerking everytime I drive sometimes acceleration is slow at first I took my car to carmax and was told the issue was fixed unfortunately my car is still having this issue it’s upsetting because this is my first car & I shouldn’t have this issue when it was supposed to be fixed before my warranty ended.
Blown engine. Hole in engine block. Defective engine.
My car slowly started losing power and was not able to accelerate. My car would not go over 5 miles an hour as I pushed on the peddle. The engine was making noises every time I pushed on the peddle. My check engine light was also on. I got my car towed to AAA where they informed me that there was no oil in my engine and my engine was severely damaged. My last oil change was October 24, 2023 at 102,132 miles. I was advised my next oil change would be around 106,000. My car was reported with no oil on December 30, 2023 at 104,349 miles. My car is deemed ineligible for an extended warranty for my engine despite the recent engine recalls for Hyundais and having my car experience similar symptoms as other Hyundais with the same engine problem.
Like many of the other complaints, in 2 years I have now replaced 3 catalytic converters. Everything will be fine and then BAM car stops working. No one can find any other issues. The car is in the shop again after the engine misfire light came on. Let’s see what it is this time. I am guessing it is an engine problem but no matter how many times I look, there are no recalls. Not sure what else I can do
This car has a GDI engine, which is now known to be defective due to excessive oil consumption. I bought the car used, with Hyundai's certified inspection before selling it to me. While my daughter was driving the car on the highway, the engine suddenly balked and stopped. She pulled over to the side of the road and called for assistance. As I write this, there is still no recall on anything pertaining to the car. The mechanic said that the catalytic converter was destroyed. Oil consumption had damaged and then destroyed it, which was becoming a known thing about the GDI engines. Hyundai refuses to acknowledge the problem officially, but there is anecdotal information that some drivers with GDI engines are being given new, replacement engines to keep everything under the radar. NOTE: the first catalytic converter went bad before the 100,000 mile warrantee, but Hyundai said that the warrantee didn't cover it. I called a local dealer for an inspection; they told me that they had no one in the bays and they'd call me back. I never received any call back. I cannot afford to buy a new car, so I had a new catalytic converter installed. As predicted, the replacement converter was destroyed, also by oil consumption. I had to replace that one after the warrantee expired. I am now driving on a third catalytic converter, and suspect that it will be destroyed in about another year or so. Meanwhile, I've passed the warrantee period, and Hyundai never even took a look at it before the expiration time. My mechanic told me that Hyundai is trying to keep this quiet, because it would cost them a huge amount of money to replace those GDI engines. Meanwhile, there is a danger that if someone has that engine and doesn't know to keep pouring oil into it, they could seize up on the highway and crash. And they'll have to replace catalytic converters if the engine is not fixed or changed.
The contact owns a 2017 Hyundai Accent. The contact stated while driving 55 MPH, the vehicle stalled. The check engine warning light illuminated after the failure. The contact restarted the vehicle and drove to the dealer; however, the vehicle stalled twice while in transit to the dealer. The dealer replaced the engine cylinder, catalytic converter, and various other engine parts. Months after the repair, the contact stated that the failure returned, and the vehicle was taken back to the dealer. The contact was informed that the compression in the engine was low and that the engine needed to be replaced. The manufacturer was notified of the failure and a claim was filed; however, the claim was later denied. The vehicle was not repaired. The failure mileage was approximately 138,400.
The contact owns a 2017 Hyundai Accent. The contact stated that while her granddaughter was driving at an undisclosed speed, the vehicle made an abnormal knocking sound with the check engine and oil warning light illuminated on the instrument panel. The vehicle stalled and her granddaughter was able to pull the vehicle off to the shoulder of the roadway. Due to the failure, the vehicle was initially towed to the contact's home. The contact called the dealer but was offered no assistance. The vehicle was then towed to an independent mechanic and diagnosed with engine failure. The manufacturer was notified of the failure. The vehicle remained in the possession of the independent mechanic unrepaired. The failure mileage was unknown.
Vehicle lost power in traffic, stalled and wouldn't restart without constant and repeated attempts. Place consumer is dangerous situation for rear collision. Vehicle restated but would not engage to where acceleration would occur above 15 mile per hour, sputtering, shaking and hesitating. Vehicle had to be towed where mechanic determined Computer code Cam Shaft out of sync. The vehicle is not own by this complainant more than a year purchase. Vehicle had experiences to appear to want to stall prior to this failure. Check engine light never cam on at any point
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.
IN OCTOBER OF 2020 THE CAR HAD AN OIL CHANGE. ABOUT A MONTH LATER WHILE DRIVING DOWN THE HIGHWAY I STARTED TO HEAR A TICKING NOISE. WHEN I GOT TO MY HOUSE WE STARTED TO INVESTIGATE WHAT WAS GOING ON. FIRST WE CHECKED THE OIL WHICH WAS NOTHING BUT FUMES BUT THE OIL LIGHT NEVER CAME ON. CONFUSED AS TO WHY THERE WAS NO OIL WE KEPT INVESTIGATING BECAUSE AS STATED BEFORE THE CAR HAD AN OIL CHANGE THE MONTH PRIOR. WE REPLACED THE OIL YET AGAIN AND CONTINUED TO DRIVE THE CAR TO SEE WHAT WAS GOING ON. THE TICKING KEPT GETTING LOUDER EVEN WITH OIL BEING CHECKED DAILY. THIS CAR ONLY HAS 80,000 MILES ON IT. I FINALLY TOOK IT TO A MECHANIC WHO TOLD BE IT WAS MY ROD BERINGS I WAS GIVEN A QUOTE TO FIX IT IN WHICH WE AGREED I COULD FIX IT BUT IT WOULD TAKE SOME TIME FOR ME TO GET THE MONEY. ON SATURDAY DECEMBER 6TH I WENT TO PICK MY CAR UP FROM THE MECHANIC UNTIL I WAS ABLE TO GET THE MONEY TO FIX IT. WHILE DRIVING IT HOME I KEPT SMELLING A BURNING SCENT BUT WAS UNABLE TO ACCESS IT ON THE ROAD. I TURNED OFF ALL EXTRAS IN THE CAR (HEATER , RADIO EVERYTHING THAT WASN'T CRITICAL TO DRIVING AT THE MOMENT ). I CONTINUED TO DRIVE THE CAR HOME TAKING IT AS A EASY SPEED AND NOT TRYING TO OVERDO IT. WHEN I REACHED THE 4 WAY STOP RIGHT BY HOUSE THE CAR WAS STILL TICKING AND I SAT AT THE SIGN BEHIND SOME CARS, THE MINUTE IT WAS MY TURN TO GO FROM THE SIGN THE CAR STALLED OUT IN THE MIDDLE OF THE ROAD. THANKFULLY I WASN'T ON A MAJOR ROAD AND HAD ENOUGH TIME TO HIT MY EMERGENCY LIGHTS. THE CAR HAD TO BE TOWED TO MY HOUSE. I TRULY BELIEVE THE 2017 HYUNDAI ACCENT IS HAVING THE SAME RECALL AS SOME OF THE OTHER BUT THE CAR ISN'T LISTED. THIS PROBLEM WAS REPORTED AT THE START TO HYUNDAI CORPORATE OFFICE THEY TOOK MY NAME AND COMPLAINT BUT NO ONE HAS EVER FOLLOWED UP ON THE PROBLEM.
