2022 HYUNDAI TUCSON Service Brakes Problems

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.

During a recent accident, the driver pressed the brakes but they did not respond, almost as if they locked up. Police at the scene noted there were no skid marks on the road, suggesting the brakes never engaged. The vehicle suffered major side impact damage, including broken windows and crushed passenger-side doors, but none of the airbags deployed. This raises serious concerns about a possible brake system failure and airbag non-deployment defect. The vehicle has not yet been repaired and is available for inspection. Police have reviewed the accident, and the insurance company has also seen the vehicle, but no mechanical inspection has been completed by the manufacturer. There were no warning lights or error messages prior to the failure. The safety of the driver and passengers was put at risk because the car could not be stopped and the airbags did not deploy to provide protection.

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

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.

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.

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

The contact owns a 2022 Hyundai Tucson. The contact stated while driving approximately 20 MPH and depressing the brake pedal, the brakes and power steering malfunctioned, causing the contact to momentarily lose control of the vehicle and the vehicle drove into the middle of a busy intersection. The contact stated that the failure had occurred on two previous occasions and the vehicle was taken to the local dealer, but no cause for the failure was found. The manufacturer was not notified of the failure. The failure mileage was 300.

Mileage: 300

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.

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.

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.

Mileage: 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.

The car has been erratic in its performance since purchase. The car has a continuous issue with the suspension, electronic system, and brakes. I have reached out to Hyundai manufacturer on numerous occasion regarding the car and no one is addressing my concerns. The car drives so erratic and unpredictable that I am fearful that someone will be injured or worst. Attached is a photo of the entire system going offline, which occurs all the time, and because the whole care is computerized this poses a safety risk for me and others on the road. When the car goes offline, I no longer have control of the vehicle and all mechanical systems are down. Please help me to get this issue resolved before someone gets hurt. This is the second submission in regard to this car. 5nmjfcae4nh015882

Purchased vehicle new at dealership with less than 20 miles on it. No aftermarket parts, no accidents or issues. Normal daily conditions, and constant logging on fueleconomy.gov. 08/17/2022 at 8:15 am: Driving 45-55 mph on major freeway with a low/moderate traffic. Roughly 5 miles from home, good road conditions and good weather. Suddenly, Automatic Emergency Braking System engaged (and related cluster lights/alarms displayed on dash). There was NOT a vehicle in front of me, and nearest vehicle in front was roughly 150 ft. away. Emergency brakes engaged so forcefully that I was unable to keep my vehicle moving forward, and vehicle came to a complete stop in the left lane of major freeway. My vehicle instantly turned off (or "died") with the radio still playing, but nothing else on. Had to place the vehicle in park, push the start button, and place the vehicle in drive, in order to continue. Obviously very unexpected. Vehicle behind me had to slam on their brakes (tires squealed) and narrowly avoided hitting my vehicle by about 36-48 inches. I'm unsure how they managed to avoid not hitting me. Unfortunately, the vehicle behind that car could NOT avoid the maneuver, and hit the vehicle that was directly behind me. I do not know if the other vehicle had injured individuals, as I was trying to get out of the left lanes of the 5-lane freeway, coming from a complete stop. Essentially, my vehicle caused someone to hit the vehicle that was directly behind me. I placed my hazard lights on, immediately pushed BlueLink button, but after two (2) times of inability to hear their voices because of breakup, I pushed SOS. Ultimately drove directly to Steele South Loop Hyundai and informed them of incident. Per dealership, they were unable to duplicate the problem, and found no error codes. I am not afraid to drive my car, with only 5,500 miles on it. Requested for dealership to report to you, but do not believe they took me seriously, so I am doing this. MAJOR SAFETY HAZARD

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.
