I have a 2014 Hyundai Sonata that had its engine replaced as part of the recall. The car was taken to Hyundai of Central FL in January 2022 and repairs were completed in May 2022. Since that time the car has had several repairs that I feel are a cause of the faulty engine and or engine related to the replacement. These repairs include oxygen sensors both front and rear replaced, additional sensors, catalytic converter, transmission flush. Just in this month the car has been taken to Greenway Hyundai in Orlando weekly for a check engine light. The car was taken last week after the check engine light came on again and oxygen sensors needed to be replaced again. After the car was picked up last Wed, the check engine light on again and is currently sitting at Greenway Hyundai in Orlando for additional diagnostics. I may have to pay for diagnostic fee again and additional repairs again. So far, the repair costs exceed $3,000. The car displays show that it is one notch from overheating, runs a little sluggish, knocking noise at times and are experiencing similar issues when prior to when the engine was replaced initially back in May 2022. I am afraid of the car seizing up while I'm driving potentially causing an accident or fire as several consumers have noted the same. I have corresponded with Hyundai Corporate on several occasions asking for assistance as I quite frankly do not feel safe Hyundai or Kia vehicles. I had also asked for some type of assistance with my repair costs again that I feel are engine related otherwise why else would the check ENGINE light be displayed. In all instances Hyundai Corporate has simply skirted the greater issue and provided me with a staged response. Now I’m being told that possibly the injectors need to be replaced on a car whose engine was replaced less than 2 years ago. I’ve asked Hyundai several times to replace the car in like kind and quality because they are allowing a car to be unsafe to be operating .

Two weeks prior to this incident, I had an oil change, fuel flush, and brake flush. I was driving 35mph, my check engine light flashed, and it died in the middle of the road. Pushed it out of way and had to tow it to shop. Shop called to say my engine locked up and that it was under a recall. That they had spoken to the dealership and that my engine should be covered under warranty. I paid to have my car towed to dealership on June 2 and have yet to even have my car diagnosed from the dealership even though the shop already did. They said it locked up due to the engine overheating. I am know paying on my car and a rental without any timeline of when something will happen.

Break lights continue to burn out. In the 5 yrs I've had the vehicle this is a constant issue. I've taken the vehicle to Balise Hyundai replacing the Bulbs multiple times and replaced one Harness. Today both break lights had to have a full assembly replacement, including harness and the bulbs melted the plastic. The passenger break light even exploded that's how overheated it became. There have been no indication when these lights burn out. I've always had a stranger, neighbor, family or friend alert me that one of my lights were out. 4/26/21 a stranger driving behind pulled up next to me to alert me my tail lights were out. Not knowing break lights out is a safety hazard whether driving on street or highway. The back window has an additional light that has continued to work. In the last 3 years my driving was reduced more than 60% as I relocated to work from home. The vehicle was serviced today 6/2/21 at Hiley Hyundai who performed the most recent inspection and diagnostic on the vehicle, as well as performed the repairs.

Had my hyundai for about a year now. There are very serious issue with exterior lighting, brakes lights, rear lights. Break lighting assembly and wiring harness melts and burns to a black crisp, bulbs burst due to severe overheating during "normal operation" of the vehicle. Safety and fire hazard with rear tail light lap assembly, bulb burns extremely hot right through plastic housing unit. Unable to replace bulbs because lighting assembly melts to the socket's core and the socket melts over the bulb metal base. Expect extreme damage prohibiting replacement of any bulbs. After being pulled over repeatedly, informed exterior lights were even after just changing them.. Light bulbs burn hot rapidly, melt to the socket make it unable to get any replacement light bulbs to work because entire unit is then damaged, burnt and melted. Bulb will not fit because plastic unit has melted from circular to inward. Lights fail without the owner ever knowing until its too late. I've been parked at mall police officer informed me light was out, driving on highway pulled over 7 times given warning, repair orders due to lights out, pulled over on side street, road and lights just go out on highway. By the time bulb goes out its burned the entire unit through wiring, anything touching or around it. Change lights every 2, 3 weeks. When changing them I notice damage worsening, metal and bulb are burnt to a crisp. When I replace on side, a week or two later I have to change the other side. Creating a trickle affect. Once one goes out. Another goes out and so fourth. You literally have to replace the entire housing unit which is very expensive. Same repeats.. Did not work. My front exterior light are now out as of a week ago. Meaning I only have 1 working light. I went to the dealership and was told it would be 300 per side to get it fixed because I need new electrical wiring ! Seriously !

Tried to replace bulb with a halogen bulb instead and the base and bulb also burned.. Under assumption that doesn't burn hot. Did not work. During severe rain pre-existing issues only worsen and magnify..
