Metal in the oil and making a noise. It stalled not once but twice while driving on a highway. Had to pull over then put in park and restart. Just had oil changed and it was 1000 under needing it done again. Have no idea why metal shavings would be in the oil. Pretty sure something happened with the rods now.

Vehicle stalls/dies while driving. It stalled 2 times but when I pulled over, it would start right away. While trying to make it home, it stalled for a third time and while pulling over it started smoking so bad I thought the vehicle was going to catch on fire. Vehicle had to be towed. There is an engine recall for this vehicle but dealer is giving me the runaround. Very disappointed with how Hyundai has handled the incident that almost caused an accident that could off been deadly.

When driving in huntsville, al on city streets and the highway when I'm turning my steering wheel it makes a clicking noise and the column appears loose. The brakes are sticking and requires me to push down hard to stop my vehicle. I have replaced the front lights and back ends lights numerous times and they continue to go out frequently. I purchased new tires in June 2019 from bentley Hyundai in huntsville, al and while driving the tire tube popped and deflated. There were no nails in the tire. There was a hole in the tube. I almost crashed.

Our 2012 Sonata is now on its 3rd engine (1 original and 2 add'L). These were subject to recall. Went for my routine oil change and my mechanic pointed out that there were metal shavings in old oil and on drain plug. Are we looking at another new engine to be installed. Bought it new as a commuter car because of the warranty, but it has spent more time in shop than me driving it.

My 2012 hybrid Sonata, 104,000 miles, suddenly started jerking and nearly stalling one recent morning on a drive from home on a divided road. It barely moved forward, badly jerking, message on the screen was : hybrid battery low. Pull up safely an place the car in park". so after 1/2 mile, I returned home. Because of low speed on a divided road, there was a serious concern of being hit by another car. I had the car towed next morning to the Hyundai dealer. They reported 'nothing wrong found' and returned the car which is running fine, though jerking transmission at low speed. I am wondering if this happened away from home, what shall I do. I need assurance that that will not happen again. How do we get that assurance ?

I'm not sure if this is an engine problem. When I would take off in my car, I accelerate and after I started going, I could push the pedal all the way to the floor and it had no power, it would almost completely stall in the road. I let off gas and push again and it would regain power and drive. No check engine light came on, no low oil, no service lights at all. All of the gauges in the dash red great and everything was normal. I started my car one day and it started making this chirping noise, almost like a bird chirping when I accelerate, but once I got up in speed the chirping stopped. I then started my car and there was a clicking, ticking type noise that got worse after 2 days. I took the car to a shop and was told it needed a new engine. Again, all gauges are completely normal, no check engine light at all to warn me there might be a problem with my car and now it cant be driven. I purchased this vehicle new. Why doesnt the check engine light or gauges work to warn of possible issues, this has to he a defect and what is the chirping, stalling, loss of power" if my engine was going bad, why did the system fail to alert me"

I have now had two major issues with my hybrid. The first was 5 months ago. My husband was driving the car on the interstate, when all of the sudden he lost power and the engen started smoking and make horrible noises. We had a rod thrown through the engine and had to replace it ($3200). Then on Friday morning I was driving to work on the interstate when I lost all acceleration and the hybrid warning system started going off. I had my mechanic look at it and he told me I will need to replace my transmission, he also said this is a know problem with the Hyundai Sonata hybrids. It is about a $4000 replacement. Please help those of us that put our trust in this vehicle and are now paying for it.

I own a 2012 hyundia Sonata SE with 136,000 miles. This car has a long list of issues from purchase date of 2011 to right now. The engine/transmission has been jerking, stalling and not having full power intermittiently as of the three years but this surpasses it all. July 2, 2019. I was leaving from a parking lot in reverse and heard a loud boom noise, I thought a collision occured. I looked all around and nothing was there. So, I place the gear into drive.....boom again. My entire body shook and the car proceed to jerk and hesistate through the parking lot. Nervously, I had to get on to the dangerous interstate 35 South and the car struggled to get the optimal entrance speed onto the freeway. It jerked more and more while on there and immediately exited at the first exit. The RPM dial was extremely higher than normal. I had to take side roads to avoid being hit or hitting someone to my house. I have been slightly terrified driving this car before with the stop and go jerking combined with randomly not starting, but now I'm beyond that now. Driving the last couple days has me a nervous wreck with the reading of this issue happening nationwide with our kids in tow. Please NHTSA, make hyundia accountable with these documented unsafe cars on our roads all over the country. This is not right. Thank you

Engine failure: I own a 2012 Hyundai Sonata. On July 2, 2019, I was driving home from work on the highway in the far left lane, driving approximately 60 miles an hour when suddenly the engine stalled and the car would no longer accelerate. It then started making a knocking noise. This was a very scary occurrence especially to happen on the highway. But fortunately, I was able to slowly cross over, safely get off at the nearest exit, and pull over to the side of the road. Several warning indicator lights were flashing on the car (including the engine light) and I detected a slight burning odor (but no fire). I was able to restart the vehicle but it stalled again and eventually was towed to an independent mechanic who diagnosed a complete engine failure. The vehicle wasn't repaired but towed to the closest official Hyundai dealership (256 North franklin St, hempstead, NY) for assistance. The following recalls are associated with my vehicle: Recall# 17V226000 (engine), and #15V568000 (engine). At the time of occurrence the vehicle had oil in the tank and had approximately 88,000 miles on it which should not have affected the engine at all. I sincerely hope that by reporting this incident, it will assist the Hyundai dealership in repairing or replacing the engine in my vehicle as stated in the recall and thereby preventing this from ever happening again. This is a very dangerous incident and wouldn't want to ever subject myself or my family (who also ride in this vehicle) to a terrible incident such as this or worse.

My car's check engine light came on and I took it to the shop for diagnosing. The code P1326 came up and nobody can figure out the problem. My car doesn't accelerate properly and take a minute to shift gears and drive properly. There has been open communication on the issue by other people.

While driving straight on busy street approaching highway, car shook, all warning lights illuminated, then dimmed as car came to a stop and died in the center of the road. It could not be restarted. This happened in seconds, not affording driver enough time to move toward shoulder. As Hyundai explained, the engine failed and, in so doing, sent electric surge that also "fried" the starter. Dealer indicated there were photos of engine after incident. Local mechanic said that after removing the starter, visual inspection allowed him to determine a new engine was needed. This is consistent with Hyundai's explanation. There were no problems with this car prior. Two prior engine-related safety recalls (issued in response to this problem) were performed on this vehicle, and no safety problems were detected. Hyundai advised this is a known issue for Sonatas, and they remain unable to determine when/where this will happen to any Sonata. A local dealer had several on lot with same issue. Engine and starter need to be replaced, and it remains undetermined if any other components were impacted.
