2011 Hyundai Sonata: whining or grinding noise

Filed Feb 19, 2023 · Transmission · MO

I was driving my vehicle and a warning light indicating hybrid system charging failure warning. The vehicle had intermittent power problems and would not move appropriately in relation to the pushing the gas pedal. It would not go then would jerk forward. I was finally able to pull over to the side of the road safely. I turned my car off and when turned back on the error message failed. This happened on two other occasions. Later there was a whining noise when shifting into second gear. I took in for service and the hyundai dealership told me the transmission needed to be replaced. My safety and others were at risk due to loss of ability to drive the vehicle appropriately due to loss of power.

My engine has failed, and my steering wheel column has locked. I had the software update on my engine with Napleton that qualified me for a lifetime engine replacement. I submitted maintenance records for my car and pictures of my valvetrain that are well maintained, and hyundai denied my engine claim for exceptional maintenance neglect on Dec8. On December 14th, after reviewing my oil changes, they still denied me for using low quality oil that's obscured. The problem I am having with my car is oil, not being able to get to the pistons inside my engine. It's not fair when the company know they engines have a manufacture defect. Then they blame the customers for lack of maintenance to have an excuse not to replace the engine. Knowing that with or without oil changes in the hyundai sonata 2011 -2012 models the engines will eventually seize anyway.I've reached out to their company over 300 times trying to resolve this matter and I'm still in the same place I started at a month ago. I want to sue for pain and suffering. I've been without a car since nov 9, and it's dec 20. Hyundai has put me and my family life in danger on numerous occasions, with their faulty and defected parts causing two near death experiences. Hyundai sonata has had a recall on every part, and I consider them unsafe and dangerous. I have seven different case reports with Hyundai motor company about excessive oil consumption, and the knocking whining vibrating and shaking. They are very much aware of everything

Took car to dealership for engine recall check in 2016, was told my car was fine only to have the engine seize 12 months later while driving. Engine was replaced by northtowne hyundai in kc, mo and car was returned after 7 weeks. Within a few days of driving with the new engine I heard a distinct whining at about 2500 RPM and noticed a steady leak due to spots on my driveway. I returned the car to the dealership who said that the leak was from the transmission and that they have no liability since the engine replacement did not cause them to have to actually touch the transmission since the two systems are completely independent of one another. Corporate hyundai says that the powertrain (I.e. Transmission) is not covered under their extended 120,000 mile warranty and the cost of the repair is going to be an out of pocket expense to me.

I was driving in town @ slow speed, & put on brakes to stop at a stop sign/cross walk. I began to brake a car & half length from the cross walk. The car did not stop & I felt it pull forward, felt a vibration in the brake peddle & hear the motor making a low revving or whining sound. The car went through the cross walk & into the middle of the intersection. At that point I took my foot off the brake & drove on until I found a place to pull over. The brakes were fine when I stopped the car at the parking spot. I left the car running & called my hyundai dealership. Explained the problem & explained that I was alarmed by this. The guy told me it was probably my ABS brakes kicking in as it was raining. I have driven cars for years with ABS brakes & had them kick in & this did not feel the same. This felt like my car was pulling forward rather than ABS brakes activating. I could not stop the car with my foot on the brake peddle. This is the second time this has happened in the last 5 months. But I don't have the date of that incident. Both times I called the dealership. I was told to keep driving the car today & if it does it again to schedule an appointment as they have had some problems with the ABS brakes. I am going on vacation in a couple of days & the dealership is 50 miles away, so I can't just stop by when this happens. My concern, which I expressed to the dealership, is that if someone had been in the cross walk I would have hit them as I had no way to stop the car and it was pulling forward. Or if I car had been coming through the intersection, I would have been hit and it would have been my fault. I am less than 3000 from my warranty being up and told the dealership to make a note of this as a problem at this point. I see where there are others who have had the exact same problem. I am very concerned that this is a dangerous situation with this car.

I started the car in the parking garage and a high pitched whine was produced while the esp light was flashing. I turned the motor off and restarted and the issue went away, later that evening after leaving a restaurant I started the car and the loud high pitch whine started again with the esp light flashing. Of great concern was the steering wheel began shaking violently and would not stop. The car was not drivable so I pulled to the side of the parking lot and turned off the engine. The steering wheel would not stop shaking and did so for about 30 minutes until it stopped. The loud noise also stopped. I called hyundai assistance and it was going to be morning before I could get it towed. I have had cars give trouble in the past but not like this where I was extremely concerned for my safety.
