    There is a recall of our 2012 Hyundai Sonata but Hyundai never informed us of the recall. https://autoservice.hyundaiusa.com/Campaign132/sitecontents/English/CustomerLetters/site_97_page_1530_customerLetter1.pdf#pdfjs.action=download Our car qualifies for the recall but Hyundai does not want to do anything about it. Our car experienced engine knocking and we took it to an independent repair shop. The repair shop informed us about the recall but Hyundai never did. The recall is because there is a defect in the engine in which friction caused by metal bits burned up the oil. The low level of oil causes the knocking. The repair shop filled our car engine with oil. We took the car to a Hyundai dealership but they refuse to do the repairs unless the engine is knocking even though the recall letter admits there is a potential safety issue if the engine is not replaced.

    The car starts alarming out of nowhere while driving at 70 mph on the interstate and the Hybrid System Warning - Safely Stop and Do Not Drive along with the wrench, battery light and engine light all appearing on the dashboard to pull over and do not drive when this occurred I lost total control of the vehicle. The brake peddle goes all the way to the floor enabling me to stop and I lost the ability to steer the vehicle as the power steering went out as well while this was happening. I almost got killed as I was on the highway driving at 70 mph. I immediately put on my hazards lights to signal to other drivers that I was having mechanical problems. Thank GOD I was able to pull over without anyone hitting me from behind. I have had major major issues with this car since I purchased it the engine seized up on me in the same manner back in 2020 and the engine was replaced. Then there was an issue with the transmission and that was also replaced. Then the brake booster also failed and had to be replaced as well. Hyundai aught to be ashamed of the production of this vehicle as it is truly a severe risk to the lives of the consumers not just the person who is driving this vehicle but also to those who may be behind someone driving as this could cause a major accident and people could be killed. These cars need to be recalled and they need to get down to what is causing these issues in order to fix the problem. I pray that you all make Hyundai do a recall on this vehicle as I have googled and see that there has been many others that have encountered these same issues. I am filing this complaint in hopes of you all getting involved to do something about this. Any help with this will be greatly appreciated.

    Hyundai recall 198 was received after my engine was replaced. I started the reimbursement process with Hyundai 05/28/2021 at www.HyundaiUSA.com/Campaign198. On 11/15/2021 my reimbursement request was denied. I never received any notification about this. I only found out in early December 2021 when I checked the above website. After several subsequent communications with Hyundai, the claim was reinstated. Eventually, my claim was approved in April 2022. Per an email dated 04/12/2022, the claim was supposedly submitted for payment. I had my vehicle inspected at a Hyundai Dealer per their 03/08/2022 email. On 06/08/2022, Hyundai then requested proof of payment. I did make a partial payment of $2128.65 on 03/25/2020. Proof provided. I can't obtain any further proof of payment because I since had closed this account. Recently I requested help from the Minnesota Attorney Generals office. Hyundai responded on 10/10/2022. They won't make any payment without payment proof. I've tried doing everything Hyundai has requested yet is is never enough. I provided the repair invoice. I provided proof of inspections at a Hyundai dealer. PLEASE HELP ME. I've been dealing with this for a year and 9 months. I have endured so so much during this process. I wonder how many other Hyundai owners have been put through the hell I've had to deal with. I just want to be paid and put this horrific mater behind me once and for all. PS: This replacement engine failed me again on 05/19/2022. Hyundai has basically ruined me financially. I think they should be punished somehow.

    Approx july 2022 My sonata began to malfunction, first the steering wheel buttons stopped working intermittently off and on unable to turn on and set cruise control, unable to use hands free phone options as well as unable to navigate cluster features, as the time goes on the problem gets worse and eventually do not function ever. I replaced the steering wheel buttons which fixed the issue temporarily only now the vehicle will engage cruise control, accelerate dramatically and continue to gain speed. I am unable to disengage cruise control via the brake pedal, or cancel option or steering wheel. If I depress the brake pedal it will begin to decelerate but once I let off the brake pedal the engine will revv high and gain speed again. Buttons begin to function in a reverse order meaning press cancel, cruise turns on, press set button, cruise will set, press set button cruise will disengage etc. The only way to disengage cruise and rapid acceleration in this dangerous scenario is to Press the on off cruise control button. Immediately stopped vehicle had it towed to dealership, they stated that they could not replicate the problem, however their diagnosis for the problem was due to incorrect brake fluid put in the vehicle and suggested to completely replace the entire brake system of the vehicle I declined as I felt that was not the problem in fact bizarre diagnosis. Only hyundai dealership has ever put any brake fluid in my vehicle... this is completely dangerous as when vehicle suddenly accelerated I was unable to turn it off I almost rear ended a vehicle on the freeway going 70 mph. I no longer feel safe in the vehicle and it sits collecting dust while I make monthly payments.

    On March 19th, 2022 I was t-boned and my airbags failed to deploy causing me to slam my head against my window. I herniated two discs in my neck because of the accident. My 2012 Hyundai Sonata had just had it's engine replaced due to the engine recall and had also never been in a wreck. My airbag light came on after the wreck. Sent my car to be fixed and light went off. I was hit again 2 weeks ago and afain, airbags failed to deploy. Notified Hyundai of the situation and was told my car wasn't part of the airbag recall.
