Problem 1: I made a right turn at a red light. As I turned my power steering light turned on and my steering wheel locked up and I lost control of the vehicle. After stopping and turning off the vehicle, I restarted it. At this point I was able to regain control of the car. A few days later the same thing happened again as I made a right turn from a parking lot into the flow of traffic. One again I stopped the engine and restarted the car, then I regained control of the car. Problem 2 (May be related): My passenger side headlight was replaced a year ago. Recently the light went out again. I took the car in to a mechanic to repair it. It was repaired so I thought. Two days later the light went out again. The mechanic believes their may be an electrical issue. Problem 3 (May be related): My driver side brake light was replaced about a year ago as well. It has now gone out again. I have had my vehicle serviced twice by a Hyundai dealership at least twice since the first incident.

In May, the engine completely failed as I was driving on the freeway, without cause. It had to be towed to the dealership where luckily the engine was replaced under warranty. Less than 6 months later, the HEV and CEL warning lights came on as I was commuting to work via highway. The car was very low powered, hard to accelerate, and immediately decelerated whenever I started to let off the gas pedal. It struggled to go at or above 60-65 mph. The freeway speed was 70 mph and it was a safety risk for the car to power down. Dublin Hyundai could not replicate the problem, simply recharged the battery and said I was good to go. Less than 1 week later, the exact same thing happened as I started on a road trip. I had to return the car home and get it towed to Stockton Hyundai for diagnosis. This is car is only 6 years old, has been routinely maintained, and just hit 100k miles, for which Hyundai is denying any repair assistance even though there is a lifetime hybrid battery warranty.

Engine Shut Off Without Warning problem of the 2017 Hyundai Sonata Hybrid While driving the car on the freeway, it will jerk forward and then shortly after lose power. I pull over (luckily haven't been killed yet) on the side of the freeway. I've taken my car to a Hyundai dealership third times. All Three time I was stranded on a busy california highway. I have looked into this warning over a year and no one seems to know the problem. This should be a recall and all Hyundai dealers should be made aware of what this warning is. We as Hyundai owners need answers and help.

1) I purchased 2017 Hyundai Sonata Hybrid new. Now for 2nd time, trunk latch won't open trunk. 1st time i paid for a new park on the trunk. Now again, trunk won't open. Dealer states they have to replace rear bumper antenna. 2) Airbag light came on on the dash, and remains on when I start car. Dealer stated it is the driver seatbelt light. I Never had an accident with this vehicle and air bag(s) have never inflated. Dealer stated they will have to replace driver airbag which will cost me $1,436.35. I don't know why I have to pay for a new driver airbag when I bought the car new and never had an accident with the car.

The hybrid system failure. Chrck engine light is flashing. Abs system failure. Battery failure. Car can't go over 45mph, lost a job because of the issues. I'm afraid the car is going to blow up or catch fire. I'm afraid to drive it. The acceleration is barely there. It's like the car doesn't even wanna go. It sucks through gas like no other.

I first experienced HEV hybrid system issue back in 2022. I took my sonata to the dealership which they had over a month to try to fix the problem which they did for the time. Now a year later I-??m back with the same issues and the dealer basically saying they can-??t see my car for a month then don-??t know how long it-??s going to take to fix the issues if the even. Nobody can really tell me what-??s wrong with my car. This the second time it-??s been a safety hazard while driving on the interstate and the system malfunctions causing a hazard to me and drivers around me because the vehicle has basically cuts off rapidly slowing the vehicle down

Driving the car on the freeway, the battery light came on, and after that few other warning lights came on and I pulled over by then the car stopped and didn't turn on. It was scary since I was on the freeway. No other warning prior to that and the car was very well maintained even during the last recommended service everything was checked and no recommendation was made regarding the alternator. It was the alternator that caused the problem according to the dealer diagnosis.

This issue has happened twice in one month on my Hyundai sonata hybrid that I-??ve had for less than 3 years. It is a 2017 model. While driving on the interstate, the car will stop accelerating and all warning lights will come on along with -??Check hybrid engine. Turn off engine-??. The dealership has yet to find out the problem and cannot tell me what the issue is both times I-??ve brought it in (it-??s had ti be towed both times). I cannot afford to keep paying for repairs on an almost new car along with the safety concerns of driving it. I am attaching pictures of both times it happened- noting that it is the same warning each time. It looks like multiple owners are having this issue and none has yet to be resolved.

I have a 2017 Hyundai Sonata that has had 3 recalls. I purchased the car in 2019 and all three recalls have been issued after 2019. Since I-??ve had the car I-??ve never taken it to Hyundai to get the recalls taken care of. Until recently I took my car to get the recalls fixed and they told me they had already been taken care of. The gave me the dealers contact information and I-??ve never taken my vehicle to them they claim to have serviced my car at 122000 miles and I only have 94000 miles in my car. I believe they used my vin number to summit they fixed the recalls when my vehicle was never at their dealer. I contacted Hyundai and have not received any call back. The recalls for my vehicle are very serious recalls that I need to get fixed. One of them is the malfunctioning of the trunk latch my trunk does not open or close right now. I have a 6 month old baby and I need to put her stroller in trunk and I-??m unable to do so. Also my car vandalized twice they tried to steal it. I need the security update. I just don-??t know who I need to contact to help me get this resolved.

National Highway Traffic Safety Administration 1200 New Jersey Avenue, SE Washington, DC 20590 Subject: Anti-Theft Upgrade Request and Complaint Dear Sir/Madam, I am writing this letter as an Autochthon American woman exercising my rights to conduct commerce and practice freedom of religion, seeking assistance and resolution for a distressing incident related to the theft of my conveyance. I believe that the faulty design system of my Hyundai, which was advertised as reliable, contributed to the unfortunate incident of theft. On [date of theft], my vehicle, a [make, model, year, color, license plate number], was stolen, and it has had a severe impact on my ability to conduct commerce, generate income, and practice my religious rights freely. The theft has left me under duress, causing immense stress and a crippling financial situation. The advertised reliability of Hyundai vehicles has proven to be far from the truth in my case, as well as the experience of many others. I am seeking assistance and action from the National Highway Traffic Safety Administration to address this issue and improve the anti-theft measures in Hyundai vehicles. My inability to utilize my vehicle has significantly hindered my daily life, preventing me from engaging in productive work and fulfilling my religious obligations. I implore the National Highway Traffic Safety Administration to thoroughly investigate this matter and take necessary measures to enhance the security and anti-theft features in Hyundai vehicles. I kindly request the following actions: 1. An investigation into the reported faulty design system contributing to the theft of my vehicle and its impact on others. 2. A prompt recall and implementation of an effective anti-theft upgrade for all affected Hyundai models to prevent similar incidents in the future. 3. Adequate compensation or support to help alleviate the financial burden caused by the theft and its consequences. I am aware of the National Highway Traffic Safety Adm

I have financed my Hyundai Sonata Sport 2017 in December of 2019. I have not had any issues until this current year of 2023. I have noticed that with every oil change that I receive that I would have to go back to the dealership or certified mechanic a month or two earlier. I personal checked for leaks but seen no signs of why I had to get constant oil changes. Recently, when driving on the highway speed limit at 70 mph and my car went to 60 mph. The engine light came on but no other warning. I stopped the car, check the oil level which was pretty low and topped it off. I let the car sit for a short while as I was only 5 mins away from home. Soon as I made it back, I check the oil level again which was in the line. Check for visible leaks. I figured my car shook as it did and idle at the speed do to a misfire with the spark plugs/coils which I had already replaced 2 months prior to the incident. I was able to use a car scanner from AutoZone to check for codes but there wasn't an engine light at all on the dashboard. There was only one code that did show which was P1326 but no engine light or flashing engine light. I then schedule an appointment for an oil change and to confirm that the engine light code was with Firestone Auto Care to analyze the issue. They did an overall check over on the car, checked for codes, and changed the oil in which they found no issues. With driving my car to test if there were any issues it completely shut down and did not want to start. They called me to tell me that the engine was locked. They tried turning the engine over multiple times, but nothing would start up. Due to not knowing what was going on with my vehicle I felt unsafe with driving it as it completely slowed down on the highway. As other cars where speeding by. It gave no indications prior to the incident that anything was wrong. I am waiting to see a Hyundai dealership to inspect my vehicle which they are booked until next month. My car is currently disabled.

My 2017 Hyundai hybrid PHEV vehicle stuttered and failed to accelerate when the gas pedal was depressed and a warning light indicated a problem which was confirmed as a failed battery in January 2023. I was advised by the Hyundai Sonata service center 13 weeks ago that the vehicle was unsafe to drive due to a defective battery. They have not been able to replace the battery or provide an estimate of when the replacement battery will be delivered. The battery has a lifetime warranty but the Hyundai company and dealership is not providing a loaner vehicle or reimbursing me for rental vehicle while the unsafe vehicle sits in the service center for more than 3 months. Please help.

Problem began Dec. 2021. Has occurred on 16 occasions since then. Warning light "Check Hybrid System; Turn off Engine" comes on while driving. The car then shuts off the engine and there is a 100% loss of motive power. Sometimes is associated with very rough braking with the car "knocking'." On 3 occasions there has been partial/near complete loss of braking power. All incidents have occurred while under power, so far all while under 45 mph. No accidents yet. Two near collisions from the rear. Hyundai was notified of the problem Dec. 2021/Jan. 2022. After a month of testing they stated the car needed a new plug-in hybrid battery. One was not available and due to "supply chain issues" is still not available 15 months later. Dealership provided a loaner vehicle Jan to Sept. 2022. They requested their car back and Hyundai initially agreed to cover the cost of a rental car. I rented a car for 6 weeks in Sept.-Oct. 2022 at which point a new case manager informed me that Hyundai would not pay for a rental vehicle any longer (note: they did reimburse me the cost of those 6 weeks rental). Hyundai is well aware of the safety issues involved in driving this vehicle. However, they have chosen to ignore them. Their attorney, in a letter to the Ohio Attorney General's Office, blamed the lack of a plug in hybrid battery on supply chain issues (letter was Nov. 2022, at which time the battery was supposed to be available March 2023) and only stated that my vehicle was "drivable." Another warning message "High System Temperature; Switching to Hybrid Mode" has been occurring for a couple of years periodically. Since October 2022, the malfunction indicator lamp is always on and 99% of the time the "Check Hybrid System!" warning light also comes on after about a minute after starting the vehicle. On 3 other occasions the vehicle has entered into "limp home mode" instead of complete shutdown.

The vehicle has stalled in traffic numerous times since I bought it in 2016 creating a traffic safety issue. Without warning the lights on the dash will flash and the car dies. I have worried each time that traffic behind me would collide with my car. #1 1 1/2 years into ownership this occurred. They replaced part of the EV charging system that was overheating on the cars. (RECALL) # 2 1 /2 years into ownership the air-conditioner failed and the car stalled in traffic due the air-conditioner failing. (REPLACED UNDER EXTENDED WARRANTY) # 3 Last year I complained that a Hybrid Overheat Message would come on switching to EV mode and the transmission felt like it was slipping occasionally, and the battery only held 20 miles of charge, rated for 27. They refused to change the battery system under the lifetime warranty. #4 Last summer car stopped charging (REPLACED INVERETER UNDER EXTENDED WARRANTY) This month car stalled on the roadway, lights flashed on dashboard. Could have been rear-ended, Had to coast to a stop and restart the car. Took to dealer the said the replaced an EV computer for 5K (REPLACED COMPUTER UNDER EXTENDED WARRANTY) 3 days later same issue, stalled on busy street without warning. Took to dealer and the replaced the cars main battery, charging me $450 3 Days later it stalled again without warning in traffic, It's not back in the shop. THIS VEHICLE HAS MAJOR SAFETY PROBLEM. IT'S EXTREMELY DANGEROUS TO HAVE A CAR STALL IN TRAFFIC WITHOUT ANY PRE-WARNING. THE DESIGN IS DEFECTIVE. THE CARS NEED TO BE RECALLED AND BOUGHT BACK AT FULL PRICE BY THE HYUNDAI.

I took my car to a shop due to my car having a loud knocking noise coming from the engine bay and lack of acceleration as well as the oil light flickering on and off and once the mechanic inspected my vehicle he said metal particles were being deposited into my oil due to internal engine parts. After picking my car up all the lights on the dash cut on and the car completely had no steering, no brakes, no power but the radio still worked. I barely could turn the steering wheel nor could stop the vehicle due to this and thankfully could coast into an upgrade leveled hill and stop the car. Car would barely recrank or hold power nor would go above 40 mph. Only drove 5 miles to get the car back home safely. Drove back around 3:00 a.m. so there wouldn't be much traffic out in case of something like this happening. Could've been catastrophic!
