Had took it and called servals times to dealer complaining that something is wrong with the engine all they said is get a new car even thou was still making payments and told me warranty was not covered. After waiting a year later asked again and said warranty was covered due to the recall but when I took ot they denied my engine replaced saying I caused the head gasket to be replaced. Explaining the car showed no signs of over heating and just shut off once I got off the exit.

Driving down the road my car just shut down and wouldn't start it happened once before but I was able to jump it and it worked but this time after we replace the battery and got it running there was a knocking under the hood that sounds like a rod going out or the engine is toast. There's no knocking before the engine totally just shut down it was running perfectly fine and because it started and ran fine the last time the car just died when I was driving I thought it was the battery and low and behold I replaced the battery and it turns on perfectly fine but now the knocking in the engine. It also will not drive over so many miles per hour cuz if it goes up to those miles per hour then it shuts down or the knocking gets louder and it starts to die. Again no warning about this which is why I replace the battery cuz that's what happened last time and when it came back on this time after getting the battery replaced and put in lonely hold there's knocking in the engine and it won't drive. I've seen on YouTube a guy with the same problem find out there is something recalled on the engines for the 2011 Hyundai sonata. The manufacturer replaced his engine for the same exact thing my car is doing. I just inherited this vehicle from my dad who passed away but he had just put it in his name from my brothers who passed away from COVID so I have not had this car long at all. Literally just received title in the mail. This is my only vehicle and my husband is blind and we have two kids that we have to get to and from school and very limited income right now and this problem needs to be fixed by the manufacturer because I did nothing wrong

The contact owned a 2015 Hyundai Sonata. The contact stated that while driving at approximately 60 mph, the vehicle decelerated independently while the check engine warning light illuminated.

VISIBILITY:SUN/MOON ROOF ASSEMBLY
I have had NO previous issues with my sunroof. On Thursday, March 31st at approximately 5:30 pm, as I drove home from work. There was a breezing sound immediately after which my sunroof was pulled from the vehicle. Projected about 30 feet in the air according to the witness and crashed in the middle of the road. Fortunately, there was no one hurt or injured. I was shocked and a bit shaken up. I pulled over got out of the car and recover the frame of the apparatus. The front deflector appeared unattached and I had to hold it down to keep from flapping to bring the car home. After some research as to how this major and possibly like-threatening incident could have occurred. I found numerous articles regarding the deflector unbonding and cause tracking issues with sunroof and disengagement. This is highly concerning and I believe Hyundai should be responsible for the repairs in full as this is a safety concern that is the result of defect.

There is a recall on my 2012 Hyundai Sonata motor. Which has caused the motor to lock up. Hyundai is refusing to fix the recall issue. Both dealership and customer care have stated that the motor locked up due to the recall but they are refusing to fix the issue, stating it is my fault. My car had 130k miles on it. The dealership has had my car for 2 months and they never contact me regarding the progress on my car, I have had to contact them.

ENGINE
This vehicle is consuming large amounts of oil. Up to 3 quarts and 1,000 miles causing the oil light to come on. Hyundai did an oil consumption test with failing results. Due to this they did a deep combustion chamber cleaning. The car still continues to burn excessive amounts of oil. I am told that this does not qualify for the class action lawsuit because it is piston related and not rod bearing related. There is a burning smell coming from the vehicle that does not smell like burning oil. I am highly concerned that the vehicle is going to catch on fire yet Hyundai refuses to do anything about it.

On 04/09/2022 around 6:30 PM EDT, while driving on the Florida Turnpike at the posted 70 mph in Orlando FL, the 2015 Sonata Hybrid suddenly shut down in the center of 4-lanes with heavy traffic. The engine would not run and only sputtered and jerked when I gave it any gas. The display screen lit up with multiple failure symbols including the Hybrid System failure, lane detection failure, and several others. I exited the Turnpike and had a local auto store scan the vehicle finding the following DTC’s: 1. P1326: Excessive connecting rod bearing wear 2. U0293: Lost Communication with Hybrid Powertrain Control Module 3. U1004: Not certain The vehicle was checked and found to be full of oil. The vehicle was serviced at the Hyundai Dealer on 02/25/2022 where they specifically updated the “Excessive connecting rod bearing wear” knock sensor software along with a turn signal issue. Having the engine go into a default mode at 70 mph in heavy traffic was a near disaster. A simple warning would have been adequate to all me to safely navigate to the roadside.

STARTED OIL CONSUMPTION TESTING IN AUG 2021 THROUGH HYUNDAI DUE TO THE VEHICLE TAKING IN AT LEAST 1.5 QTS OF OIL EVERY 1,000 MILES. AFTER MULTIPLE TESTS, HYUNDAI COMPLETED A COMBUSTION CLEANING IN JAN 2022. NO CHANGES. AFTER AN ADDITIONAL OIL CONSUMPTION TEST IN MARCH 2022, HYUNDAI HAS ADVISED THIS IS NORMAL CONSUMPTION. NO ACTION TO BE TAKEN FROM DEALER/CORP UNTIL ENGINE BLOWS A ROD. MANUFACTURER &/OR DEALER PREFERS FOR MY FAMILY TO SUFFER A DANGEROUS AND POTENTIALLY CATASTROPHIC EVENT BEFORE ADDRESSING WHAT IS TO BE A KNOWN ISSUE WITH THIS YEAR/MAKE/MODEL.

ENGINE, FUEL/PROPULSION SYSTEM
When entering freeway and needing to get up to speed real quick, the car will accelerate to approximately 50mph and then engine totally cuts out like the gas stopped flowing to it. I then have to let off on the gas considerably or it will not accelerate until I let off on the gas about 1/2 way. I then must "Slowly" accelerate so that it won't cut the engine again. This will happen anywhere if I take off from 0 mph and try to accelerate with peddle eventually going to floor, the car will cut the engine and will feel like its dying until I let off on the gas peddle all the way and then slowly accelerate the vehicle up to speed.

While sitting at a stop light the vehicle suddenly would not accelerate and would not rev the engine above approximately 2000 rpm. Then the check engine light began to flash. I was nearly rear ended because the vehicle just would not accelerate.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
IF I drive long distances for 30 minutes or more and then stop in somewhere and shut the vehicle off. Once I try and start it, it will give the Yellow CIL Check engine light and the HEV error, bring car to dealer. You have to wait approx 15-25 minutes and then it will start up again. I also seem to notice that it happens even faster when I put the transmission speed control into High Performance. The battery seems to overcharge and go well past the halfway mark almost to 80% and then once I power off and back on vehicle, I get the HEV error message and must wait 15-25 minutes before it will start.

It all started with the electronic system. Both of my brake lights burned, leaving huge holes in the back of my brake light bracket. Replace the whole brake assembly on both brake light fixtures, then now my horn is not working—nothing to do with the relay or fuse.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS
I had a safety recall on my car for the Smart Junction Box. I took the car to the dealership on March 9th 2022. They updated the software that controlls the Smart Juntion Box. On March 11th 2022 at 6:45am I got in a car accident due to the automatic braking system failure. I run into a Ford F-150 at the stop light. Even the brakes at this point failed to work properly as well. I called the deslership and explained what happened to me and I was told by the technician that there is a possibility that the update of the software that runs the Smart Junction Box has impacted the Smart Cruize Control. He said there is a possibility that the Smart Cruize Control settings have been erased to default so the car needed a new settings. That was something I did not know about. My car has the option where you can choose what distance you want between your car and the car in fromt of you. It goes from one-space car to four-space cars. So according to the technician this may has been the problem.

SERVICE BRAKES
The check engine light intermittently comes on, when on the car will stall when trying to accelerate, often accelerate when not intended, and runs rough. A second issue seems to be with the ABS system. On several occasions the ABS systems seems to engage and will not allow you to use the breaks (almost leading to several rear end collisions).

This vehicle's engine made a rattling noise and then suddenly stalled while I was driving it. I had it towed to the closest manufacturer dealership and the mechanic submitted a claim on my behalf to the manufacturer. It denied because the car has a salvage title. After reviewing your website it looks like the manufacturer can not solely deny a recall claim based on salvage title. This vehicle's engine has acted just like all the other recall's on this manufacturer, make & model.
