2012 Hyundai Sonata: grinding or squealing brakes

Filed Jan 4, 2025 · CA

Car went complete stall after a warning light came off “Hybrid System Warning - Check Brakes” I am completely braked, but when I slowly releasing the brake pedal, there’s was a loud grinding noice and the wheels wouldn’t go forward at all, so I have to step on the brake again . I got stuck IN THE MIDDLE of the road and couldn’t park on the right curb since the car randomly got stalled completely. It took almost 40mins for the warning issue to go away and the car went back to normal. However, IT’S COMPLETELY A SAFETY ISSUE for the car to randomly stall in the middle of driving! I could be driving to fast traffic on a freeway or wide street where accidents can occur since I couldn’t even drive it a bit to park on the curb. On top of this - I occasionally get “hybrid system warning” whenever I am in the middle of driving and I always have to pull over and wait at least half an hour for it to go away, it’s been happening for few years now, and tonight was the most dangerous one so far!!! Please make Hyundai do a recall on the hybrid battery diagnose or replacement

The grid warning light is coming on and telling me to stop the car. When this occurs the car will lose power and the brakes will start making a grinding noise. My safety was at risk when I was driving on [XXX], Chula Vista, California by Southwestern Community College approaching behind cars at a red light intersection on the second lane to the right going east and the warning light came on. The car started making a grinding noise and to lose power. The intersection was busy and I was barely able to get the vehicle to the right lane to get out of the way of traffic going east. I was blocking the right turn lane onto [XXX] in Chula Vista, Ca I took the vehicle to the dealer and has been confirmed. It first appeared approximately in July / August of 2023.

Several times a week I get "Hybrid System Warning. Check Brakes" that comes with red flashing light on the dash and beeping noise. When I turn the car off, give it a few seconds and restart the car, it goes away. It has mostly been happening when I am parked so it is not an issue to shut it off and restart. Two days ago, this happened while I have driving on the street and when I applied the brakes, it went down to the floor with grinding noise. I was going about 35 MPH and no cars in front of me so I was able to come to a stop on the street with hazards on. I turned off the car, restarted it and the issue went away. I have researched this online and it looks like many people are having the same issue. Many have taken their vehicle to the dealer to get the issue fixed and the dealer is unable to fix the issue because they cannot recreate the problem. I am afraid that this might lead into an accident and feel like something that Hyundai should do a recall on.

I recently purchased a Hyundai Sonata hybrid with 132K miles on it and it has been driving fine for at least two weeks until a few days back the car has been displaying a recurring alarm on the dashboard telling " hybrid system warming! Safely Stop and Do Not Drive " now as soon as I turn on the vehicle the alarm comes on immediately. It's been a week since the car is technically inoperable because if I attempt to drive the car it makes this horrible grinding sound which is terrifying considering if I drive like this it would probably cause more damage to the car, and I have look for information on this issue and have found many of these cases over the years that I can relate to but unfortunately there's no a recall of this problem. I'm taking the car to the dealership soon but I don't have any hopes that they will find a permanent fix for this since nobody has apparently. I'm just trying find some help with this issue. So far I just have lots of regrets about this purchase and just hoping I can find some help with this matter.

About 1 month after I bought this vehicle, late December 2021, a warning light came on the hybrid screen, it read "Hybrid System Warning! Safely Stop And Do Not Drive!" The accelerator was not working I pulled over and turned the vehicle off. I waited a couple minutes and restarted it up again and went on my merry way. About a month later it happened again!! It's happened about every 5 weeks until June 16th at about 5pm, it now permanently chimes and beeps with the Hybrid screen warning me of the same, my foot brake goes to the bottom and makes a grinding noise. I am not able to drive it more than 100 yards or so then the accelerator fails again. I owned a mechanic shop and I know my brakes are fine, there has to be something wrong with the brake pumps/master cylinder, the brake fluid reservoir is full and the brakes electrical components make a horrible noise when I depress the foot pedal, I've read on Hyundai Forum on-line, that this has happened to various others, its happened on the freeway while I was going about 70mph!! It's happened on busy city streets with 45mph speed limits. Hyundai doesn't want to take any responsibility for it! What can I do? The dealer wants $200 to have it checked with no guarantee that they'll find the problem. Thank you [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

On March 19th I was involved in wreck where the other driver was at fault. The lady t-boned me on my driver's side. Airbags never deployed so my head smashed Into the window leaving me with a concussionand spinal injury. My usually working horn failed as well. I would also like to mention that I have only had this car a year. I was also told it was never in a wreck and had 1 owner. Nope. A week after I got it, I was driving and my engine seized while I was doing 70mph. The steering stopped working, but somehow managed to pull off to the side. i had to stay in my car because of the busy highway. It was 100+ weather and my windows wouldn't work. I sat there for 2 hours. Took the car to a shop just to find out about the engine recall that I believe my car wasn't apart of, but should have been. Fought with Hyundai for them to fix it then lost my job because I was denied a loaner car while waiting. 2 months later they finally fix it. Now the breaks do a weird grinding thing a lot, my shifter slips out of place, the steering column wobbles, the engine is constantly making a disturbing noise and is sluggish, it has trouble shifting when accelerating. I have had the car rapidly accelerate instead of slow down when stopping at a stop sign or light. I only got it to stop after stomping the breaks repeatedly while throwing it in park and turning the car off all at the same time. Emergency break and traction control light come on a lot. It's throwing a high speed can bus code, but only sometimes. My gas mileage has went down to 16-18 mpg. Oil changes are necessary every month. AND my taillights burn out every 1 to 2 months. Now I have 4 traffic tickets. And that was all BEFORE the wreck. Hyundai refuses to call me back after they reluctantly fixed the first recall.

The contact owns a 2012 Hyundai Sonata. The contact stated that upon depression of the brake pedal, an abnormal grinding noise would emit from the brake pedal without warning. The contact had taken the vehicle to a dealer where they found no fault with the vehicle. The contact had taken the vehicle back to the dealer on multiple occasions where software updates were performed and rotors were replaced; however, the failure persisted. The contact had also taken the vehicle to an independent mechanic and the driver’s side rear brake caliper piston was replaced; however, the repair did not correct the failure. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 35,000.
