2017 Hyundai Sonata: multiple warning lights

Filed Aug 5, 2025 · Acceleration, Engine · MI

I am leasing a 2017 Hyundai Sonata from Car City in Michigan. In May 2025, the vehicle received a brand-new engine replacement due to previous problems. I picked the car up on [XXX], and on the same day, the vehicle began malfunctioning. It would not accelerate properly, jerked and stalled, and multiple warning lights — including the check engine light — came on immediately. This made the car unsafe to drive. I contacted the dealer, but they told me to wait until Monday to get it looked at, leaving me with a dangerous and unreliable car. The vehicle had already been in the shop for over two months for the engine issue, and I had only driven it for six months beforehand. I believe the repair or replacement engine is defective or was not properly installed. This creates a serious safety hazard. A car that stalls while driving puts everyone at risk. I am filing this complaint so this issue can be investigated and addressed if others are affected. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving on the highway the car began shaking, the check engine light came on. After guiding the car to the shoulder, we turned the car off and back on after a few minutes. The engine was completely stalled when we turned the car back on - multiple dash lights were on (check engine, oil, and battery were the ones I remember); the car would not accelerate, when we attempted to drive slowly the car, in drive, started rolling backwards/downhill and would not accelerate at all; and the engine was still idling shakily. Car was towed to a mechanic who diagnosed an engine misfire requiring engine replacement. Hyundai dealership denied this as a warrantable issue under Extended Warranty TXXI/TXXC/Service Campaign T3G. This vehicle is a well-kept 2017 with only 90k miles and should not have had this type of engine failure except as a result of poor manufacture.

I’ve had my 2017 Hyundai Sonata for approximately 1 year, purchased through a Carmax dealership. With no explanation, while making a left hand turn the steering wheel locked for about 1-2 seconds and all lights related to the steering and braking system appeared on the dashboard, they instantly disappeared and my steering wheel was usable again. This same incident happened an hour later making a right hand turn, as well as a third time going straight over a speed bump: This issue is intermittent, occurring fairly rarely, however it’s terrifying and extremely dangerous to drive the car now. The vehicle is full on power steering fluid and hasn’t been in any accidents. I’ve talked to numerous people with this same issue. This will kill somebody if it isn’t addressed as a recall. Most people can’t afford to have intermittent problems diagnosed, due to most auto shops / dealerships not being able to help unless there are warning lights on the dashboard. Please help

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!

I just bought this car about 10 days ago everything was great until about 2 days ago, I started feeing my steering wheel lock for a little bit or get extremely loose. It did that a couple times through out the day and everything was fine. Next day about the same thing. I thought it was weird. Now today I was driving and felt the same sensation of stiffness on the steering wheel but still able to drive then boom steering wheel locks completely and multiple lights come on. This was extremely scary and I'm already traumatized by other incidents in my life. I like the car but this error in the system is so risky. After turning the car off and on , steering wheel began to work normal. hopefully this does not happen when I am on highway !

Steering wheel and response was "intermittently" grinding and non-responsive. This situation has occurred sporadically over the course of the fall of 2021. On December 17, 2021 while on the way to work, the steering system "froze" while I was driving and put me in a very dangerous and hazardous situation. Dash warning lights indicated a red steering wheel symbol with a cross-line and the orange anti-skid symbol at the time of the incident. I immediately stopped the car and turned it off. Upon re-start, all dash warning lights were off and the steering seemed to work normally. I next carefully and slowly drove the car to my local car repair shop. They could not duplicate the problem, but felt certain it was the electronic power steering module that was failing intermittently. My local shop strongly recommended I have the vehicle towed to the Hyundai dealership for evaluation and repair. I had the car towed to Huffines Hyundai in Plano, Texas on Dec. 21, 2021. After three weeks in at the Huffines Plano Service Shop, the service manager called and stated they are unable to duplicate the problem and to "come pick up your car". I have called and created an incident report with Hyundai National Help line, but to date, no resolution has been offered other than "come get your car". This is clearly a driver and road safety issue. When the steering failed, I could not turn the wheel at all. The car was out of my control. Stopping was the only thing I still had control of, and even this was dangerous as I was on a very busy 6-lane divided thoroughfare. This electrical (or mechanical) failure put me and all other drivers around in a dangerous situation. Clearly, I am not comfortable retrieving this car and putting it back on the road.

On numerous occasions, the steering wheel feels loose after starting but then begins to work normally. On 7/27/2021, as I was backing out of the driveway, there was excessive steering wheel motion where the wheels did not turn at all even though the steering wheel was turned in each direction about 10 degrees. Then the power steering completely stopped working at all, and I had to steer the car to the curb with extreme effort since the power assist was completely gone. Several dash warning lights were illuminated including the traction control light. After turning the car off, and then back on, the steering was back to normal. I have continued driving the car for the last three days and the problem has not recurred. But I am very nervous about the safety aspect of this and don't enjoy driving the car anymore. I am the original owner of the car and it only has about 28000 miles on it.

Engine turned off when stopped at a stop light. All the lights turned on and I had to put the car in park and turn the car back on. The engine also struggles to start when it is parked in cold air. It also struggles to start anytime its parked in a parking garage.
