2015 Hyundai Sonata Brakes Problems

I was turning into a parking spot and the car accelerated unexpectedly. I slammed into a snow bank and my front bumper was damaged.

The turning signal gives the opposite signals sometimes.

Location: [XXX] Description of Incident: On a rainy morning, while driving to work, I encountered a sudden lane cut-off by a speeding truck as I exited a school zone. I applied the brakes to avoid a forward collision, but the brake system failed entirely. This resulted in the loss of vehicle traction, causing the car to spin out uncontrollably. The vehicle collided with an island, bounced into oncoming traffic, and sustained severe damage, including: •Tires ripped off the rims •Front axle damage Injuries: I sustained a lightly sprained neck as a result of the incident. Vehicle History: The vehicle had been in the custody of the Hyundai dealership just days prior to this incident for an engine/powertrain recall and replacement. The dealership held the car for over a week to address the issue. However, shortly after retrieving the vehicle, the brake failure occurred. Observations and Concerns: •The brake failure occurred after recent service by the manufacturer dealership. •Hyundai vehicles are known to have documented brake system issues, which may have contributed to this incident. •This failure nearly resulted in a life-threatening accident. Action Requested: I am requesting an investigation into the service performed during the recall and the brake system failure. It is imperative to determine accountability and address any potential defects to prevent future occurrences. [XXX] [XXX] - Victim and incident reporter.

The contact owns a 2015 Hyundai Sonata. The contact stated that the ABS and traction control warning lights were illuminated.

The manufacturer was contacted, who opened a case, but no assistance was provided. The failure mileage was approximately 84,107.

Recall notifications for Hyundai campaign 251 but no remedy available since early 2023. Finally learned a remedy was available, made online appointment with my dealership (Future Hyundai of Concord, Concord, CA) but when I arrived for my appointment, they said they did not have the part. That was April 29, 2024. I was told to follow up in a week, which I did. Part still not available. Followed up several more times to which I have not received any response. I am driving a potentially very dangerous car now awaiting this recall remedy. Last year I waited 5 months for a new Hybrid battery with similar lack of communication and delays.

When driving my 2015 Hyundai Sonata Hybrid, it will randomly start flashing and beeping at me with the saying "check brakes" Also my ABS Brake light comes on. This function only happens at random causing me to shut off my car completely and restart. It has really become a problem after I reached 112000 miles on the vehicle. I bought the vehicle with 80,000 miles. Anyone driving in my car is put at risk due to brakes not working accurately and are spongy feeling when pressed down. If I were to have to slam on brakes, I would ultimately run into another vehicle or object since the braking system during this issue does not work correctly. I have called the dealership to ask about the recall. No recall on this issue but online, similar issues have been documented.

The check engine light intermittently comes on, when on the car will stall when trying to accelerate, often accelerate when not intended, and runs rough. A second issue seems to be with the ABS system. On several occasions the ABS systems seems to engage and will not allow you to use the breaks (almost leading to several rear end collisions).

The contact owns a 2015 Hyundai Sonata. The contact stated that the engine was consuming an excessive amount of engine oil. There was no warning light illuminated. The contact was frequently topping off the engine oil between scheduled oil change service. The vehicle was taken to a dealer and a 3,000-mile oil consumption test was performed. The test concluded that the vehicle was consuming an excessive amount of engine oil. The contact rejected the results. In addition, the contact stated that the brake pads were frequently replaced due to the vehicle shuddering upon the depression of the brake pedal. The manufacturer had been notified of the failure. The vehicle was not repaired. The failure mileage was approximately 60,000.

Vehichle goes into limp mode on highway causing a drastic reduction in speed. Dash says hybrid alert do not drive. Loss of speed put me in danger due to loss of power and vehicle control. Dealer claims it is a bad brake booster that caused car to go into limp mode… Want to charge me 3k to fix.

THE EMERGENCY PARKING BRAKE LIGHT DOES NOT COME ON WHEN SET, HOWEVER PARKING BRAKE DOES FUNCTION.

TPMS MODULE FAILURE IN CONCERT WITH ABS MODULE FAILURE. RESULT IN INCREASED BRAKING EFFORT, WARNING LIGHTS AND SPEEDOMETER INOPERATIVE

BRAKES AND ROTORS HAVE BEEN REPLACED. NOTICED THAT IT'S TAKING LONGER FOR ME TO STOP ALONG WITH SQUEALING OF FRONT BRAKES.

FOR THE PAST 6 MONTHS I'VE BEEN EXPERIENCING BRAKE ISSUES. IT HAPPENS RANDOMLY, SOMETIMES WHILE I AM DRIVING (AT SPEEDS RANGING FROM 20-65 MPH) AND SOMETIMES WHEN I AM STOPPED AT A STOP SIGN. IT EVEN HAPPENED WHILE I WAS SITTING IN TRAFFIC ON A HILL DRIVING INTO YOSEMITE VALLEY! WHEN IT HAPPEND, THE CAR ISSUES A WARNING SAYING THAT THERE IS A BRAKE FAILURE AND TO PULL OVER SAFELY. IT FEELS AS IF SOMETHING IS DRAGGING ON THE FRONT WHEELS AND THE CAR STOPS ON ITS OWN. I TOOK IT TO LOCAL MECHANIC BUT THEY COULDN'T DIAGNOSE THE ISSUE AND SUGGESTED I TAKE IT TO HYUNDAI. I TOOK IT INTO HYUNDAI THIS WEEKEND AND THE MECHANIC SAID THAT THEY WERE FAMILIAR WITH THE ISSUE AND SAYS IT HAS SOMETHING TO DO WITH THE HYDRAULIC BRAKES ALERTING THE SYSTEM TO BRAKE WHEN IT SHOULDN'T BE. IT'S GOING TO COST ME AROUND $2500 TO FIX IT, WHICH IS A HEFTY SUM AND UNFORTUNATELY WILL HAVE TO COME OUT OF MY WEDDING BUDGET FOR MY WEDDING IN 6 MONTHS. IT SOUNDS LIKE SOMETHING HYUNDAI SHOULD TAKE CARE OF. THIS IS INCREDIBLY DANGEROUS, I COULD'VE GOTTEN INTO AN ACCIDENT IF THE CARS BEHIND AND AROUND ME WERE NOT PAYING ATTENTION WHEN THE BRAKE FAILURES OCCURRED. I THOUGHT I WOULD BE OKAY IF IT HAPPENED AFTER ONCE OR TWICE. BUT I GOT REALLY SCARED WHEN IT HAPPENED IN YOSEMITE SINCE THERE WAS NO PLACE TO PULL OVER SO I DECIDED TO TAKE IT IN.

AT 91000 MILES THE HYDRAULIC BRAKING SYSTEM FAILED. HYUNDAI HAS A 100000 MILE WARRANTY ON THE POWERTRAIN FOR THIS VEHICLE BUT THEY REFUSED TO REPAIR THE CAR UNDER WARRANTY. THIS IS A PRETTY COMMON PROBLEM AND I BELIEVE THAT THERE SHOULD BE A RECALL AT LEAST, IF THEY ARE NOT GOING TO COVER IT UNDER WARRANTY. REPAIRS ARE ASTRONOMICALLY EXPENSIVE. I WAS QUOTED MORE THAN 7000 DOLLARS TO FIX THE PROBLEM. WHEN THE PROBLEM OCCURED, THE BRAKES BECOME UNUSABLE AND THE CAR HAD TO BE TOWED TO THE DEALERSHIP. I THINK HYUNDAI AND ITS DEALERS SHOULD BE HELD ACCOUNTABLE FOR THIS TYPE OF FAILURE.

WHEN PARKING OR DRIVING AT ANY SPEED THE ABS AND TRACTION ICONS HIGHLIGHT AT RANDOM MOMENTS AND MAY STAY ON WHILE DRIVING OR MAY TURN OFF.

I SEEN MY VEHICLE HAD A RECALL ABOUT THE BRAKE LIGHT. I SEEN IT FLASHING SO I THOUGHT SOMETHING WAS WRONG WITH MY BRAKES I HAD THEM CHANGE MY WHEEL BARRELS CHANGED ROUTERS CHANGED AND IT STILL MAKE A SCRUBBING NOISE
