2022 Hyundai Tucson Brakes Problems

While driving at highway speed with cruise control and lane-keeping assist active, a semi-truck suddenly moved into your lane. Your Forward Collision Warning system didn't alert you, your Adaptive Cruise Control didn't slow the car, and when you pressed the brake pedal, the brakes didn't respond. You collided with the semi at approximately 60 mph and subsequently hit a concrete barrier. A brake system inspection and diagnostic scan of the collision avoidance and adaptive cruise control systems will be necessary to determine why these safety features failed to activate.

Vehicle randomly activated automatic emergency braking and the forward collision warning with no other vehicles in sight. The vehicle slammed on the brakes almost causing a trailing car to rear end our vehicle. This has happened 5 times with speeds between 40 and 80 mph over the past 4 weeks. Conditions were cloudy. Problem has not been reproduced by the dealorship. No inspections have occurred.

It’s been three years now and I had “Brake system failure” happened two times in 3 years. When traveling the brake system warning appears and while driving, and stopped at sign brake releases slightly and car would start to move unless I apply brakes firmly again. When slowing down at traffic lights holding the brake doesn’t bring car to complete stop. I had apply brake, slightly release and then apply again until car comes to full stop. I was told they need to replace IEB module and brake pedal module replacement. I checked in Reddit and other platforms where users had seen the issue multiple times on their vehicles. Also had an issue with Fuel system like replacement of Egr valve which seems to be common on multiple Vehicles.

I took the vehicle to the service station because it takes a long time to stop, and I braked close to a vehicle on several occasions. They replaced the brake pads, and when I took the baby in, it was worse. When they finally agreed to let me take the baby in for another inspection, they said they would have to remove and reinstall the parts. Two months later, my baby started doing the same thing.

The vehicle's brake system intermittently fails after driving over bumps or uneven roads. The brake pedal becomes soft and unresponsive, and the vehicle continues rolling forward for several seconds before the brakes finally engage. This has happened repeatedly while driving home from work. On one occasion, the vehicle rolled through a red light and I had to swerve into oncoming traffic to avoid a collision. This issue first became noticeable in 2022 and has worsened over time. It puts both my safety and the safety of others at serious risk. There are no warning lights or error messages before or during the failure. The vehicle is available for inspection upon request. Independent mechanics have confirmed that brake pads, rotors, and fluid levels are in good condition. They suggested the cause could be air in the brake lines, a malfunctioning ABS system, or a faulty master cylinder—all potentially covered by the manufacturer’s warranty. The manufacturer’s service center initially refused to inspect the vehicle without an upfront diagnostic fee and only offered assistance after I escalated the matter through repeated complaints. The service director later described the issue as “unsettling but normal,” which is not accurate according to independent professionals. The problem has not been resolved and continues to occur regularly. I am requesting that this be formally investigated as a potential safety defect.

Master cylinder for the brakes went out

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.

While driving on the highway at approximately 65 mph the car emergency brake kicked in with no cars in front of it. Causing a huge jerk. This happened 3 times within a 25 minute time span

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.

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.

There was no warning light illuminated. The vehicle was taken to the dealer, where the tires were replaced; however, the failure persisted. The vehicle was taken to the dealer several times. The dealer informed the contact that they could not duplicate the failure. The vehicle was taken to a second dealer, where it was test driven; however, the dealer could not duplicate the failure. Additionally, the contact stated that the brake pedal was pulsating while depressed. The vehicle was taken to dealer, where the brake rotors size was reduced; however, the failure persisted. The dealer advised the contact to take the vehicle to their location for the same repair to be completed. The vehicle was not diagnosed nor repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 3.

The contact owns a 2022 Hyundai Tucson. The contact stated while driving approximately 70 MPH down a mountain, the brake pedal was depressed, and the vehicle started vibrating abnormally. There were no warning lights illuminated. The contact took the vehicle to the dealer who diagnosed that the front brake rotors hot spots. The rotors were turned. The manufacturer was not made aware of the failure. The approximate failure mileage was 76,000.

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.

I was in a turning lane & a driver swerved in front of me. My car is equipped with auto start stop and it was on. I slammed on my brakes and the engine turned off. When I tried to start restart the car there was a fluttering/grinding noise. Turned off the key and restarted the car. Dangerous in the intersection with a stalled car. At the dealer now but not optimistic. Annoying to have to turn off feature each time.
