2023 Hyundai Tucson

While driving on a highway shortly after taking delivery of this vehicle as a Certified Pre-Owned purchase from an authorized Hyundai dealership, I experienced sudden and total brake failure. The Electronic Parking Brake (EPB) warning light illuminated and an audible warning chime sounded. The brake pedal did not respond normally. I was unable to slow the vehicle with the brakes and was forced to make an emergency maneuver to exit the highway and come to a safe stop. Upon inspecting the vehicle after stopping, I discovered that the rear left brake caliper had completely detached from its mounting bracket. The caliper was on the ground beneath the rear of the vehicle. Brake fluid had leaked onto the road surface. The vehicle had been in my possession for less than one full drive since purchase. As part of the CPO certification, the selling dealer performed a multi-point inspection and documented installation of new brake pads and certified the brake system as in good working order. The detachment of the caliper is consistent with mounting bolts that were either not reinstalled or not properly torqued following the dealer's brake service during CPO preparation. I have photographic evidence of the detached caliper and brake fluid loss. INJURIES: None, but significant risk to myself and other highway drivers. FIRES: No. MEDICAL ATTENTION: Not required. CONTACT WITH DEALER/MANUFACTURER: Yes — Hyundai corporate complaint filed. I am requesting this complaint be investigated as a potential safety defect related to brake service practices during Hyundai CPO vehicle preparation.

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.

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.

For the second time in a year, I was pulling into a parking space and when I applied the brake, the car accelerated, seemed to be airborne and lurched forward. Though I firmly had my foot on the break, it would not stop until it hit a brick post about three feet away. This exact same scenario happened in July of last year. Then, I hit a stand of shrubs. Someone said, your foot must have slipped off the break and hit the accelerator. I said, “I don’t think so.” Yet, I took the blame for the accident, for I could not believe it was a car malfunction, nothing close to this had happened to me since I owned the car. Everything was the same in the last crash as in the first. This time, as soon as the car accelerated, I checked, and my foot was firmly on the break. There is definitely a malfunction in the car. The black.box Should be recovered and read by someone not associated with Hyundai. I checked on Hyundai Tucson Owners’ group on Facebook, and my incident has been reported by others.

I previously leased my vehicle from Rick Case Hyundai in April 2023, In November i started having issues with my vehicle as i moved to Colorado. My whole vehicle starts to uncontrollably shake going 25 mph and over. Since highway speed limit is 65 that is where i struggle the most with driving and that is the most endangering as well. I have to pump my breaks and hope they don't stop working. I have taken my car to get a diagnostic multiple times at different dealerships and each time i went to another dealership they advised a different problem I can send an email or mail with all attachments of diagnostic reports from Hyundai dealership. Each dealership advised one of these problems, engine, brakes, rotors, tires, etc, although the vehicle was a few months old! I reported lemon l to Hyundai Customer service with 2 different attempts and they denied my lemon law and advised i should pay for anything not under warranty. Although the vehicle has a manufacture defect i will be continuing to attempt different dealerships to help my cause since i am endangering myself and everyone around me. I have done enough research to know i am not the only person with this problem and this should be a recall defect. I need a solution so i can drive in the state i live in ,Colorado, and not be scared for my life that my car will stop working at some point.

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.
