I want to say through this message exactly a month ago that I bought my Hyundai sonata sel 2023 and today driving the car it completely lost power when accelerating so I had to stop immediately I put my turn signals after that I turned off the car! I opened the hood and I didn't see any smoke coming out until that part, everything was fine. Then when I tried to start the car, it made a strange noise and a strong smell of gasoline began to come out! try several times and the same result that the car does not start the engine makes strange noise and the smell of gasoline is very strong that I had to get out of the car and leave it off, at the time I write this message I am still waiting for assistance!
I was driving on the freeway, at the speed limit, cruising along. Then all of a sudden, my vehicle starts to decelerate from 65 MPH and I push the gas, thinking I must have let up too much on the pedal. However, that only causes the RPM to drastically rise with NO change in my speed. I thankfully managed to maneuver from the far left lane to the freeway shoulder on the far right. The whole time, my speed was around 40 MPH and dropping drastically. Trying to safely navigate a slowing vehicle on a 65+ Texas freeway is an adrenaline-rush that I wouldn’t wish on anybody. I was severely panicking. I was almost hit by several vehicles in my maneuvering. I could have died last night. Once on the shoulder, I tried to start my car. I thought it may be a battery issue, but it turned on. It didn't start, though. The lights came on, as did all of the typical system/dash lights that usually indicate when a car’s engine hasn’t “turned over.” I used Bluelink to call for roadside assistance (since I’m only a little over 2 months into ownership) and waited. I was escorted off of the freeway to safety — thanks to a 3-car police escort AND free city tow trucks — and eventually picked up by Hyundai-serviced AAA. The latter then towed my vehicle to the dealership where I bought my Sonata. My car is currently being checked/inspected by my dealer (North Freeway Hyundai) and I only have gotten the following notice from Bluelink: "A possible condition with your Engine Control System has been detected with your 2023 SONATA on 02/22/2023 at 07:23 am CST. A full system check is recommended to be done soon." I checked and there are no open recalls (currently). Even more concerning, my car recently underwent complimentary maintenance, including an oil change, through my dealer (on February 13, 2023 - I have the receipt), was good on gas, and had no warning lights displaying. Until it stopped running — the time I tried to start it on the side of the road, the dash showed an “engine” light.
While on the highway, my car suddenly started shaking violently and losing power. I lost steering and was unable to accelerate. I pulled over to the side of the road and the vehicle would not start again. I took it in and a fuel injector was stuck open and it had flooded my engine. This was the second time with this vehicle that this happened.
