2023 Hyundai Tucson Brakes Problems

I parked my car on a driveway with a slight incline. After putting the car in park, I stepped out of the vehicle and the car rolled back into the street. I brought the car back into the driveway, again put the car in park and engaged the parking brake this time. The car rolled back out into the street again. Thankfully, the grandchildren were not playing behind the car and there was no one was parked behind me.

Engine misfiring, causing low power on interstate 70 also losing brake control.

My vehicle has been in for service 4 times for the front brake rotors warping. The dealer/manufacturer is not able to fix nor diagnose the root cause of the issue. They have replaced the rotors twice and turned/resurfaced the rotors twice - all in 26000 miles. The dealer has all but given up on the issue - and has referred me to Hyundai Customer Care (Corporate) where I have logged a case. In my discussions with the dealer service manager - he stated there are "half a dozen" other cars he is aware of with similar issues. In online Hyundai owners forums this is also a "known" issue that apparently Hyundai either chooses not to fix or cannot determine how to fix.

I was driving on a highway at 75 mph, on a clear day, with perfect visibility and driving conditions and my automatic emergency braking engaged. I was on cruise control with no one in front of me for approximately half a mile. There were cars behind me, so I had to swerve into another lane to avoid being rear ended. There was a sequence of beeps. If there were warning lights or messages, I was too busy dodging to see them. There may have been a squiggly line that came up, but I am unsure.

The contact owns a 2023 Hyundai Tucson. The contact stated while driving 20 MPH approaching a RED traffic light and depressing the brake pedal, the vehicle failed to stop as needed. The contact steered the vehicle on a patch of grass nearby and shifted into neutral(N) to stop the vehicle. There were no warning lights illuminated. The battery was detached and reconnected to reset the vehicle. The contact was able to drive the vehicle at low speeds. The dealer was contacted and informed of the failure. The dealer stated that without warning lights being illuminated they would not be able to diagnose the vehicle to determine the cause of the failure. The vehicle had not been taken to the dealer to be diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was 22,600.

While driving 35mph on a 3-lane street in the far left lane, a driver of a Ford F-150 was in the center lane about two car lengths ahead, decided to make a right turn onto a residential street (as if he were driving a semi). As I got closer, the forward collision warning suddenly alerted and immediately initiated emergency braking system causing all 3 passengers to be thrown forward. I hit the steering wheel before seat belt caught me. I was not even within distance and he was turning in opposite direction of my lane. There also seems to be sensitivity issues with lane keeping feature as in Phoenix, there are never ending freeway construction with make-shift lanes not always marked well. On several occasions the steering wheel was jerked out of my hands because it couldn’t detect the lanes any longer. It has caused me to avoid freeways all together and has made me miss the exit off the freeway twice now. I thought this feature only activated during active cruise control, but apparently it does it regardless. Now I’m beginning to have problems with display going out at the worst times. I will be taking my Tucson to a dealer to have them deactivate both systems & advise of display. I shouldn’t have to pay for this. I’ll take over the driving, thank you very much!

While driving my new Tucson, the emergency brake randomly activated bringing the car to a jarring stop. Very scary and its happened twice now. Dealer won't help as its intermittent so very frustrating.

On multiple occasions, my new Hyundai Tucson randomly deployed emergency brakes while traveling on highway. This created a dangerous condition as my vehicle started braking without reason which prompted vehicle following my vehicle to slam on their brakes.

I was driving on the highway at 60/70 mph and there was nothing in front of my car. The brakes went on for a second stopping the car abruptly and I swerved. This happened once more. It then happened another time on a turn as I tried to regain control of the car it swerved from side to side and almost got into an accident or spun out.

The contact owns a 2023 Hyundai Tucson. The contact stated while driving at an undisclosed speed, the ABS, check engine, low oil pressure, and Forward Collision Avoidance warning lights illuminated. The vehicle was taken to the dealer but was not yet diagnosed. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 6,200.

I leased a 2023 Hyundai Tucson AWD, and approximately four months after leasing, I began experiencing vibration and shaking when braking, especially at higher speeds and downhill. I brought the issue to a dealership, and while replacing the brake pads temporarily resolved the problem, I am concerned it will return, as many other Tucson owners have reported similar recurring issues even after rotor or pad replacement. This raises concerns about a potential underlying defect in the braking system that may not have been properly addressed. The issue poses a serious safety risk due to reduced control during braking, and I am documenting this in case it recurs. No warning lights appeared, but the problem was physically noticeable and confirmed by the service center. The vehicle is available for inspection upon request. I have a video i can send as per request i am not able to attach.

on 04/16/23 I got into my car and Immediately after going into drive the brakes completely failed. The car continued accelerating even after releasing the accelerator and refused to stop even while pumping the brakes. Thank god I turned into a tree and missed pedestrians. the car was totaled.

Vehicle was purchased new from local Hyundai dealership in Dubuque, IA on November 17, 2022 and delivered November 22nd. Vehicle had just under 200 miles on odometer. Brake system was working well at that time. On January 21, 2023 I stopped for a red light. After a few seconds the brake pedal started going down and went completely down. Mileage at that time was just over 1700 miles. I took the car into the dealership on January 23rd and they checked the system and said that it was normal. The shop supervisor said that it was not a problem that when the pedal went down it was applying more pressure to the brake system. I disagreed with them as this is usually the fault of master cylinder seals leaking. They brought a newer vehicle into the shop and it had the same problem so no repairs were made. I believe this is an accident waiting to happen and I would like to have the problem corrected. This appears to be a problem with Hyundai vehicles. Our vehicle is a Hyundai Tucson.
