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.

I purchased my 2012 Hyundai Sonata on 4-7-22. The car has had no mechanical work, no accidents and has less than 1000 miles. On 9-16-22 i was driving my car home and was less than five minutes away on the highway. My car began to decelerate, I attempted to stop at a red light but my car would not give me control and the brake was rock solid and would not push down. I also could not turn the car off via the start button as the car would not let me. My engine ESC light came on the dashboard in red and the engine completely halted. To get to safety as i was on the highway with oncoming traffic i steered the car to the right on the ramp.I exited the vehicle as it began to smoke, i thought it would catch fire so i moved far away and called my boyfriend for help and a tow truck to get the vehicle. The vehicle was towed to College park Hyundai 9500 Baltimore Ave., College park, MD 20740.I looked up my car and noticed there are recalls for this engine and a few other recalls as i told the dealership. The car is currently being inspected and the dealer said they would get back to me. Once the service department received the car they told me the recall most likely will not effect my vehicle. I don't believe that to be true and i was put in danger because of this engine issue with Hyundai.

My vehicle stopped in December 2020. The dealer, Hyundai of PR, did not issue a recall for this issue. I could have been driving on the highway and loss power. THIS IS DANGEROUS. The manufacturer should be Required to notify all affected Hyundai Sonata owners via all types of media. If I hadn't known about this recall I would have paid for an engine out of my pocket.

Engine failed while driving, causing vehicle to stall and forced to the side of the road while transporting children. I had vehicle towed to dealership and learned that this was a known manufacturing defect, one that I had previously had recall service to repair and eventually a class action lawsuit. I had previously taken the vehicle to the dealership to perform recall repair. They claimed this repair was completed, even though the defect still remained and caused engine to fail. The mechanic advised that a rod from engine was discharged, which "could have killed someone". The dealership initially approved an engine replacement due to known defect and class action lawsuit settlement, but then denied repair due to unrelated branded title. Hyundai corporate refuses to take responsibility for this defect, due to title status, that could have seriously injured or killed someone. One Hyundai agent advised during a phone call on 8/22/22 that Hyundai is not responsible for remedying any manufacturing defects if the vehicle has branded title, which is in contradiction to federal law. This is a grave safety concern and should be investigated by the NHTSA. I would be glad to participate in such an investigation, providing call records, names of witnesses, statements and documents as needed.

I was on the expressway and car hesitated and jerked while speed began to increase followed by hybrid warning system alert. (Pull over and stop the vehicle) with a flashing ready light. Could have caused a major accident with loss of life as there was no place to safely pull over. Warning lights came in immediately after the cat jerked.

I was on the highway during rush hour when the car was rattling during acceleration. I was going around 75mph. The car just died in the middle of traffic and I coasted to the berm. Once stopped, it smelled like something was burning and I had my 2 small children in the back in 5 point harnesses. They couldn't unbuckle themselves and I could not get the back door to unlock with the key fob to get into the back seat to help them. Once they were able to loosen their buckles, they had to crawl through the front seat to get out. Had the car actually caught on fire, I wouldn't have been able to get my children out in time. This was the absolute scariest ordeal I've ever been in. One shop has said the engine has seized. It's now sitting at Hyundai waiting for them to look at it. No warning lights came on until the car died.

When arriving at a stop and then making a turn on a street vehicle came to a halt. It would not turn on again. The vehicle was able to be pushed to the side, and started to have a knocking sound from the engine, after vehicle was started. Searching thru the internet found recall campaign 312, that has same issues I experienced. Vehicle is drivable but has loud knocking sound as the speed goes up. Also, vehicle was purchased with a rebuilt title and is road worthiness.
