2020 Hyundai Tucson

In August/September 2025 my mother's Tucson would randomly shut down on her (completely stall while driving) and she would not be able to turn it back on. If she waited a little while, then she would be able to turn the car back on but it was unknown when the issue would happen again. We took it to the dealer several times after each shutdown and the dealer stated it was not throwing a code and they could not diagnose the problem. The last time we took it to the dealer, the vehicle shut down while they were test driving it and they discovered it was a rear wheel sensor which is part of the ABS system. When the car would stall, lights on the dashboard would start flashing and the car would shudder to a stall. Since repairing that rear wheel sensor, the car has not exhibited the issue until 3 days ago when it again shut down randomly while she was in traffic. This, of course was terribly frightening for her as cars were honking at her and whipping around her vehicle. She was not able to get the car started. A police officer came and parked behind her car, calmed her down, and got her to try the car one more time and it did start up and she was able to proceed to the closest parking lot. After that we followed her home and have an appt. set to go back to the dealership. We are expecting the same run around at the dealer who charges excessive fees to diagnose and then repair the car. My Mom is [XXX] so this is a dangerous vehicle for her to be driving (really for anyone) as I am reading on line others reporting this same condition. I am expecting that they will find that a different rear wheel sensor has failed for which they will want another $800.00 to repair or maybe more now. Obviously we must get rid of this vehicle. It has less than 25,000 miles on it because she only drives to the grocery store and back. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Component: Engine / Electrical System / Fuel System Incident Date: February 9th, 2026 Vehicle Speed: 45-50 MPH Description: While traveling at highway speeds on a major roadway, the vehicle experienced a catastrophic and sudden engine stall without any prior warning or dashboard indicators. The engine shut off completely while in motion, resulting in an immediate and total loss of power steering and power-assisted braking. I was forced to perform a high-effort emergency maneuver in heavy traffic to reach the shoulder and avoid a collision. This vehicle is used to transport myself, my coworker and my family whose lives was placed in immediate danger by this failure. Since the start of the financing agreement, this vehicle has a documented history of recurring sensor issues and failed repair attempts at the dealership (Route 1 Hyundai). The dealership has previously attempted to address electrical/sensor malfunctions, but the root cause remains unresolved, leading to this life-threatening stall. I believe this is a significant safety defect in the vehicle’s electrical or fuel management system that poses an unreasonable risk of accidents and injury.

I have experienced 4 repeated issues within 4 months with my vehicle. Starting in September 2025 and the 4th and current issue today 1/12/26. Driving when all of a sudden all of my brake components lamps come on dash oard, forward collision alert, and check engine, my vehicle struggles to accelerate accurately. Blue Link diagnostic throws various codes such as ECM, Transmission Control System, even "multiple possible issues". Each time my vehicle has been at Hyundai dealership for repair. Each time they repair something different 1st- replace ABS module and hydraulic brake, 2nd - happened out of state at my mother funeral and replaced my ECM, 3rd couldn't figure it out and guessed it was my Forward collision camera and replaced it, 4th - is today and awaiting dealership diagnosis. This issue has left me stranded several times local and long distance, occured in middle of driving including on highway, and overall uncertain of the safety and reliability of the vehicle as each time it has been the same type of issue. I have been in communication with Hyundai Corporate since October and they stated that even tho I only have 24k miles on the vehicle that it is outside the state of IN lemon laws for a buyback. If I hadn't purchased an extended warranty I would be in even more debt or unable to put it in the shop even tho I don't feel like this should be my burden when I have kept this vehicle in great shape, low mileage, frequent oil changes, etc . however the safety of my vehicles goes unresolved. At this point I am uncertain that Hyundai is properly diagnosing my vehicle and not certain how these issues are impacting other components of my vehicle such as brakes, transmission, engine, sensors. I am the only owner of this vehicle bought brand new. I have checked repeatedly for any recalls that I have not addressed and at this time none are pending. I fear that this vehicle will continue to have more safety issues.

At times, this vehicle will refuse to go. You will get an alert in the dash that the emergency braking system has engaged. It may be a door is not completely shut, or sometimes it's just that I don't have my seat belt on. It seems to be inconsistent, because I often times put my seat belt on after I finish backing out, and am ready to go forward. If there is any kind of incident that requires a fast escape, this "feature" could cost somebody their life, or cause them to deal with a carjacking. The car needs to go when I tell it to go.

Our daughter was notified by another driver at a stoplight that her brake lights were not working. The car's brake sensors indicated the brake lights were not working, while driving the light went off and the lights worked again momentarily. The Hyundai dealership refused to address the problem when it was taken in for maintenance because the light did not appear for them they said it wasn't possible to a fix it. After an online search, there are instructions on what to do if you are a DIY person. They are very basic if you know your way around the electrical system in the auto. Our daughter lives and works in the Phoenix metro area putting her at risk from collision and being in violation of local ordinance regarding vehicle operation. There were no earlier indications of a problem until 5 days ago.

Electrical rear brake system. My rear driver side brake like sometimes fails to operate properly. Brake warning light on dash comes on. This happens on and off. After researching the issue I found numerous owners are having the same issue. Some replace the bulb multiple times while others have had dealerships replace the harness. Both solutions only temporarily fixed the problem for a short time

from time to time, when stepping on the brakes the whole front end shakes . when this happended i took the 2020 tucson back to the dealer to be checked out. I was told there was nothing wrong with it. and i was just not use to abs. I"m not stupid. i've had many , many cars and suv'''s, trucks with abs. this made me mad. and guess what, it still locks up. i

While driving one evening, it was brought to my attention that my passenger brake light was remaining on, when I was not braking. A week later, both sides are on. This happens only if my headlights are on - automatically or if I manually turn my headlights on. The back center light will only come on when I high the brake pedals. Again, back brake lights on driver and passenger side remain on regardless of brake pedal is engaged.
