A rod from the engine made a hole in the engine the destroyed the engine. My wife was driving on a highway wen the failure occurred. She was lucky to be able to get off the highway and safely onto medium before car came to complete stop. The dealer confirmed a rod destroyed the engine. Hyundai asked photos of the engine and other components. No warning lights came on before the failure. The only symptom was the engine was consuming a quart of oil every 1000 miles.

Engine burns too much oil and needs oil replenishment every 2 weeks while driving only 100-200 miles. This is extremely hazardous cause on highway the car can stall anytime which has happened in the past. The engine has been fixed for leaks before but still is burning oil and no mechanic will touch it saying it is a common issue of hyundai. Why is this model no part of the class action lawsuit?

Engine not holding pressure. Week of September 22, 2024. Had to have car towed either [XXX] or [XXX] by Champion Towing to Columbus Hyundai. Spoke with Rodney Cockrell. Engine not holding pressure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Engine turned off running. Car was at Hyundai Dealer, Puerto Rico for 5 months. The car belongs to campaign lots 21-01-066H and 19-01-006H-2, which establishes alternative transportation service, or rental car coverage, the transportation service was denied. In addition, Hyundai PR did not provide me with a warranty period for the new or remanufactured engine, fuel pump and starter. A complaint was filed with DACO (government agency) and it was found in favor of the defendants Hyundai de PR and Sojitz (Cataño, PR) since they did not issue documentation reporting that it was covered under the campaign, they argue that it was as a courtesy (good will) which they also did not present evidence of. After repaired (200 miles) the car presented low voltage, code P0234-P0236 overboost condition, the unit was verified presenting broken cables from one tail of the map sensor. I incurred transportation and crane expenses, and the repair of the cables, and the replacement of the map sensor.
The vehicle experienced an engine failure with minimal warning. While driving 35-50 miles per hour, I experienced a loss of power upon acceleration. Within 1 mile of the trouble starting the check engine light came on. I was able to drive less than 5 more miles before the engine completely stalled and would not restart. The vehicle was towed to an independent service center, where I was informed the engine needed to be replaced. It was then towed to my home and is still there, without repairs.
I took the car for 4 recalls it had 2 of which were physical and the other two were software according to them. Took the car back to drop someone off, turned it off and then on; it began losing and breaking on its own at slow rpm-??s slamming on the breaks. a minute later after having turned the corner I turned on my hazards and it had continued to randomly happen to the car. It is not consistent it is completely random and I have had a mechanic only inspect it while it happened once because I-??ve only been able to have it happen while being inspected out of luck. I-??ve gotten several error codes to the car since from p04 misfires. Evap leaks etc. the car was in pitch perfect condition and after that day it has since stopped working properly. I have photos of the mechanics that day even leaving food in the back of my car as if they just relaxed and didn-??t do their job as professional as it could-??ve have been. They denied anything is wrong with the car and have offered me discounted inspections after claiming nothing was wrong they gave me one free inspection and I haven-??t gone back. My engine or censors are messed up. It puts my health and others at safety because it slams on the breaks unknowingly and randomly at low RPMs. The manufacturer has inspected my car and claimed it was okay although they unprofessionally left food and ate breakfast and left trash in the back. (With photo proof). Last there was NO issues whatsoever with my car until that day. Never had a misfire. Never had a engine light. Never had a popped tire. It all began they DAY I got my car back not even an hour later. I could not return that day because it was near closing time of the dealership and the day after I went they denied it has been tampered. This happened around the beginning of July 1-8th 2023.

My transmission literally went out once on me the SECOND DAY after I financed it. Now, less than a year later, it says I need to replace the transmission again. This is ridiculous.
My vehicle has an oil consumption problem despite the fact that my car has been excluded from the class action lawsuit. I-??ve had it in the shop and they have confirmed the oil consumption issues. There are countless other vehicles excluded from the class action lawsuit that have the same theta engine as the other vehicles that were included in the lawsuit. This needs to be investigated. I still owe over 6k on my car and it-??s one trip away from being completely undriveable
The contact's husband owns a 2015 Hyundai Sonata. The contact stated while the vehicle was at an independent mechanic for an oil change, the contact was informed that the vehicle was experiencing excessive oil consumption and that it was a known failure. Additionally, the contact stated while driving 73-74 MPH, the vehicle shuddered and stalled. The contact was able to pull to the side of the road. The vehicle failed to restart and was towed to an independent mechanic, where it was diagnosed that the rod bearing had caused engine failure. The dealer determined that the engine needed to be replaced. The mechanic informed the contact the failure was due to a factory defect and would reoccur even after the engine replacement. The vehicle was taken to the dealer, where the same assessment was made. The dealer filed a claim with the manufacturer and sent a diagnostic report with pictures of the failure; however, the manufacturer denied the claim several times. The contact stated that the engine was previously replaced. The manufacturer was notified of the failure. The failure mileage was approximately 152,550.
Was driving on the access road... Luckily.... When I lost all power. Turned off my car and wouldn't restart. Had it towed, 1 month later and $7500 had to get a rebuilt engine. Which now I'm having 100s of issues. Love my car but this is literally stressing me out. Bought the car 2 months before this all happened
I was driving on the highway and my engine violently started to shake and I pulled onto the shoulder and the engine shut off. I-??ve had oil leak and engine problems with this car for 2 and a half out of 3 years! I-??ve had to buy countless gallons of oil. Multiple spark plugs, coil packs, etc. You can-??t drive the car for one whole minute without it stalling in traffic and almost causing accidents. So I can-??t drive it!
No check engine light was on. Heat cold gage was normal. No lights indicated what so ever. Engine started knocking really loud turned off while driving 70 mph on the freeway when it turned back on wouldn-??t go past 20 mph. when accelerating knocking would increase. Wouldn-??t accelerate past 20 mph. Took my vehicle to my local Hyundai dealer to be assed and they told me about the 953 campaign recall. I knew nothing about. I am 4th owner to the car from a used local dealership. My local hyundai refused to replace engine as well as corporate due to 953 campaign not being installed prior to engine failure. I only had the car a year and half and engine always sounded abnormally loud. I did tell the dealership this when we purchased the car as well as a few times throughout the time we went to make payments in person and they said it was normal Hyundais have loud engines. ultimately engine turned off while driving 20 mph and failed to turn back on at all. Out of a car since July 3 2024. No rental car was provided to me and had to pay for the diagnostics fee of $195 that was suppose to be waved once claim was approved but due to the 953 campaign not being installed by any of the previous owners or dealership my claims were denied! Now Hyundai wants $9,000 to replace engine with new belts and labor together! I don-??t even have that kind of money at all!! RIDICULOUS!!
On June 30, 2024 I was driving a 2015 Hyundai Sonata and the car caught on fire. There were no warning lights/ dash indicators/ no check engine lights or other warnings present. I had just exited the highway and while sitting at a light, smoke began emanating from the hood and within seconds the smoke turned dark brown at the vents near the windshield. I immediately exited out of the vehicle. I did not have time to pull over out of traffic. The car was engulfed in flames within a very short period of time. I had only seconds to exit the car. I would have struggled to get any passengers out of the backseat safely (i.e. kids in car seats) had I not been the only one in the car at the time. We had notified Hyundai of engine concerns that began in 2023, and they had given us the runaround for many months requiring us to submit paperwork for oil changes for the lifetime of the car and to keep returning to the dealership for "testing" after driving a certain # of miles. They required us to bring the car in to have pictures of the engine taken to ensure there wasn't "neglect" to the car on our part. This excessive and lengthy process by Hyundai took several months after initial concerns were brought up with the dealer. After being required to submit voluminous amount of paperwork and several trips to the dealership for "testing", Hyundai finally agreed to replace the faulty engine. We were told we could continue to drive it until a new engine was ordered. The new engine was scheduled to be replaced on July 11, 2024 however, the car burst into flames on June 30, 2024. Had Hyundai taken appropriate action when the issue was first brought to their attention, this incident would have likely been avoided and had not endangered my life and others helping. Thank you for your attention to this incident.
