Master cylinder for the brakes went out

- Shubuta, MS, USA

While driving approximately 75 mph in the passing lane on highway, the vehicle suddenly automatically brake. Pulled back into the right lane and didn't really understand what happened. Next time i pulled out to pass and had a car on my right hand side it did the same thing. Pulled back into right hand lane and stayed there for quite some time. I then turned off the all around sensor @ and it didnt do it again but as i got closer to home the warning light came on and a message popped up. It now has the triangle caution sign on and the picture of car icon in amber. I had driven the car from my home for about 50 miles and parked car for two hours, the drove back toward home for about 20 miles when the event happened. It was dangerous and makes not want to use any of the "assist system's" going forward. I plan to wash the car today to see if the lights will go off- if they don't then i shall call dealer on Monday. This occurred on saturday. Ill be washing car today (sunday). If i had anyone driving closely behind me, i for sure would have been rear ended.

Purchased a brand new 2022 tucson. Within 2 months it went to the dealer with about 7 dash fault lights turning on (abs, Air bag, lane assist, check engine, just to name a few) and breaks engage on their own. Stayed at the dealership for over 2 months while they had the Hyundai engineers try to figure out the issue. They gave it back to me and said it was a connector in the rear door. The vehicle has been back 4 times for the same exact issues for months at a time and they keep experimenting and giving it back to me. I tried to get it exchanged for a safer one and they denied my request. I guess my families safety isn't that important to hyundai after all.

While driving the car the engine died, locking up both the gas and brake pedals. The car had to come to a stop on its own, my wife could not depress the gas or brake to stop the car. She was going through an intersection and narrowly avoided a major accident! The battery light came on, the check engine light and the car started to fill up with a smell of burning plastic and gas. When trying to turn the car back on after turning it off it would start with a major shake and bang then turn back off. All warning lights stayed on. Battery was fully charged still. Autobody shop found engine issues in their pre scan before sending it to Hyundai to warranty it as it only has 6,626 miles and is 2 years old. There was a warning of low battery while we were on vacation and the car was sitting for a few days. And a sluggish start when it sat for few days like the battery was low, but it wasn-??t based on the volt meter.

A week ago, I was driving my 2022 Tucson Hybrid Limited on the highway on my way to work around 7:50 a.m. It was a bright day, good weather. I was in the center lane when my car suddenly braked HARD and came to a stop on the highway! My foot was still on the gas pedal, but the Automatic Emergency Braking light was on. I panicked because I had no control over what the car was doing. Thankfully, I was not rear-ended and didn't cause an accident. I put on my hazard lights, shifted into park on the highway's center lane, then back into drive and it seemed fine. There was not really any traffic in front of me that I remember, but there were some cars on either side and behind me that had to swerve around me. I don't trust this car anymore. It is going to get me or someone else killed. I took it to the dealer 2 days ago and the initial inspection didn't show any problems or error codes. They told me I could have it back since there didn't seem to be a problem or they could give me a loaner car and keep testing my car. I have a loaner. I hope they find something wrong with the car, otherwise, I am afraid of my car getting me or someone else killed. I am especially scared after reading about all the others here who have had this same issue.

While driving I noticed that the navigation went out for a second and then the brakes would not work. I was about to hit the car in front of me, but the auto braking stopped the vehicle.

- Richboro, PA, USA

On multiple events brakes would not come to a full and complete stop. Many close calls of not being able to stop quickly on the highway or going down hill. The problem has been reproduced by the dealership. No warning messaging.

I was coming back from the mall on the highway doing 50mph and my truck started losing power which it has done before but this time the emergency brake came on and my truck stopped in the middle of the highway on a Saturday. Thank God no one was following me close because that would have caused a bad accident. And also sometimes after I stop at a light or stop sign my brakes harden and I can-??t press them down if that makes since and all my needles move back and fourth while the engine is making a noise but the car is still in drive but will not move. I have to hit the button to turn the car off and restart it and this has happened to me 3 times already. This is very frustrating and scary

Constantly having warning lights on, car jerking into other lanes, emergency braking randomly, brakes went to the floor and car propelled through an intersection

I turned right into my driveway at a slow speed. As I went onto the driveway, the car surged forward. To avoid driving into the garage door, I turned to the left to drive along the side of my house thinking I would be able to stop it. I kept hitting the break but the car kept going. When the vehicle did not stop, I steered to the right because I thought it could be possible that my neighbor's dog could be in the adjacent yard (to the left of my house) The ground between the houses is pitched down (to the left) towards my house and I side-swiped the back half of the side of my house. Although applying the break, my car continued after sideswiping the side of my house with the front right side of my car and went into the house behind my house causing damage to that house. My car stopped when it went into the house behind my house.

My pregnant wife-??s 2022 Hyundai Tucson lost engine power while on the interstate with our 16 month toddler in the car. Luckily she was able to get off the interstate and into a safe parking lot. The car only has 23000 miles and has been kept up with Hyundai-??s scheduled maintenance from their dealership. The engine is knocking and experiencing rough idle. Once I arrived I was able to read that there was an engine cylinder 2 misfire. About an hour later the -??MyHyundai-?? app sent the same error codes. It took the tow truck driver 15 minutes to go 10 feet to the flat bed as the car would turn its self off. Incredibly dangerous for a car less than two years old. I hate that I might-??ve gotten my wife and son such a dangerous vehicle.

It was around 7 in the morning and I was getting ready for work. My garage door was open. A neighbor started pounding on my front door telling me my garage was on fire. I opened the door from my kitchen to the garage and seen smoke but it didn't seem major. I grabbed my keys and ran outside to pull my car out of the garage. I started the car and put it in reverse. It didn't want to move so I floored it. Once I got it into the driveway I heard the neighbors yell, "Lady! Get out of the car! The car is on fire!" I jumped out and seen the car was fully engulfed and had spread to the roof of the house. I grabbed the waterhose. It was of no help so I ran into the house to get my children out. Our home and everything in it were a total loss. Also my daughters car. Two of our dogs ran away. The car has been inspected by State Farm. They stated that the fire started in the engine compartment; the right front drivers side. Electrical; most likely the ABS. There were no warnings lights or symptoms. We only had the car for 5 months, it had 8000 miles on it. The oil had been changed at the Hyundai dealership just 5 weeks prior. I have talked to numerous people with Hyundai's that have caught fire, but not a 2022 as of yet. We have signed releases for Hyundia to inspect the car in February but they have not. It is still at the local tow yard. They are also supposed to inspect the house. They have offered to buy the car back but we have not agreed. We believe we are entitled to more compensation than that. I also have videos taken by neighbors and ring doorbells.

5/17/23 took vehicle to Dick Smith Hyundai for navigation issue, after being asked to park in a different spot brakes failed and car crashed into one of the dealer cars. Since owning the car for over 14 months without any brake issue I thought maybe my foot slipped off the brake. When leaving the dealer I tried braking several times with no issue. 5/26/23 while parking the car at a restaurant the brakes failed me again and was obvious not a slip off the brake that caused the car to collide with a tree saving me and my wife from falling down a steep embankment. Severe damage to front of car. 5/27/23 Called Dick Smith Hyundai to ask about how to remedy an obvious safety issue with the brake, was told that they would not check it out until body repairs are made first and if the issue could be duplicated before Hyundai would be involved. There were no warnings of brake or other issues. This vehicle is UNSAFE to drive after body repairs are made it will have to be towed (at my expense) back to a Hyundai dealer. Police reports on both incidents, GEICO claim put in also. No other inspections at this time. this happened in Greeville SC which is our summer home,

My vehicle takes over my breaks and completely takes control of my vehicle away from me (the driver). It does this randomly. I had a hit and run in a parking lot due to this issue. I am greatly concerned for my safety.

The following is an account of what happened when the SUV's brakes failed, which caused serious damage to the 2022 Hyundai Tucson (the "SUV") and also damaged two other vehicles. On February 15 in the afternoon, The SUV was traveling approximately 20-30 mph and was rolling up to a red light. There were about 6 car lengths between the SUV and the next vehicle as driver started pressing the brakes. Driver noticed the SUV wasn't slowing down so Driver started pumping the brakes and still nothing. Driver even looked down to make sure he/she was pressing the right pedal and he/she was. The SUV was getting closer and closer to the vehicle in front. Driver kept trying the brakes, pumping, flooring, everything. The SUV would not slow or stop. Driver tried to avoid the car ahead and did all driver could think of to slow and not hit the car ahead but the SUV would not slow down. The collision warning came on as the SUV struck the right of car in front of it. The emergency braking did not come on. Further, the SUV still did not stop until the tire hit the concrete barrier in the road. The airbag did not deploy. In total three vehicles were damaged as the SUV hit one which pushed it into another at the light. Hyundai corporate consumer assistance was contacted and a case opened. The case manager did the initial reach out after the complaint but has failed to return any phone messages or emails about the case for close to a month.They were told where the vehicle was and consent signed so they could inspect and it remains available for them to do so. The dealership was contacted but the person spoken to said its a corporate issue. The SUV is at a body shop and will be sent to Hyundai for mechanical issues and we are hoping they will look at least then for cause. There were no issues before the accident. No previous brake issue. The SUV is badly damaged. It is available to inspect upon request. The accident could have caused driver or others serious harm.

On Tues Feb 7, 2023, I was traveling at approx 6:50 pm on a suburban street at the posted 35 mph limit. My car started to lose speed, slowing to 27, then about 22-24 mph. I felt as though the engine was misfiring for an unknown reason. Since I was approaching an intersection and needed to make a left-hand turn, I started to depress the brake pedal. With no oncoming traffic, I slowed not quite to a stop, made the turn, but then had extreme difficulty getting the car to accelerate, again with the engine sputtering, chugging like a misfire, and shaking. My vehicle did not seem to go beyond 15 mph, and slowed again as I turned into my destination, about 2-3 blocks from the intersection. I parked and locked the car and was in a store for approximately 10 minutes. When returning to my vehicle, it would not start-the brake pedal could not be depressed at all, it appeared extremely hard. After 1-2 minutes of gently tapping the brake pedal, it loosened and I started the car. I put the car in reverse and it stopped in the middle of the parking lot with cars almost hitting me. I saw Engine Warning lights, Battery Warning lights, and a quick message across the screen but was unable to capture the meaning. After several more attempts, the engine started but was shaking violently, but I could not go beyond 3 mph. The shaking was so strong, items on the passenger seat shifted on the floor. I chose to remain in the parking lot and call Hyundai Bluelink. Since it was dark, I remained in the vehicle with the engine running, but excessive smoke billowed from the rear of the car. It was towed to Gerald Hyundai in North Aurora. After 3 days the dealer could not find any issue, however, I refused to take the car back, as I could recall it misfiring in previous weeks but unfortunately dismissed it. I requested a Technical Case File be opened at the Dealer. I still do not have my car after 1 week. This is a very serious issue and I am aware other owners have experienced it as well.
