2025 Hyundai Tucson

During the winter, my car would activate the forward collision warning and automatic emergency braking while I was driving when there were no other vehicles in front of me or even around me. It happened several times over a few day timespan, at the time I thought it was because I had gotten a car wash when it was colder weather and maybe the water had affected the system but now I see that there is a recall for this same issue.

The underbody shield is held up partially by plastic nuts that get loose casing the shield to rattle at speed over 60mpg. I read multiple reports from other owners on reddit. Tightening these plastic nuts help ressolve the rattle temporarly, but the nuts are flimsy and keep spinning. You can't really tighten them well. A good remedy from Hyundai would be to replace these flimsy plastic nuts with metal ones that stay tightened and secure the underbody shield in place. Dealer wasn't helpful and wanted to charge $200 just to look at it

​Before I owned this car, I used to get so frustrated whenever I was driving behind this type of vehicle because the rear blinkers are mounted so incredibly low in the bottom bumper that you can't see what the driver is doing. Now that I actually own a Hyundai Tucson, I feel completely responsible for the drivers behind me. Because I know how low my blinkers and reverse lights are, I have to turn them on way before I actually turn, and I'm always worried someone will hit me when I'm in reverse. On top of that, my friends who drive behind me constantly tell me how bad it is and how hard it is to see my signals because of how low they sit.

Forward collision assist is dangerous. It engages when not necessary and has almost caused several wrecks by slamming on the brakes. There needs to be a way to permanently disable and not have to pick through a series of menus every time. Also, lately I feel like I’m fighting the lane keep assist when I’m on the highway, and it tries to move when not necessary.

The forward collision automatic braking happens randomly and for no reason causing immediate and complete stops in the middle of traffic. It whips the head forward as if a crash had occurred and causes drivers to the rear to have to suddenly brake to avoid collision. Ive had it occur multiple times since purchase with the most recent being this morning in the middle of a roundabout. I know I can disable the system but 1) that's also a safety risk and 2) it turns back on every time I start the car which is unacceptable. Ive asked the dealership about it and was told that it cannot be disabled. I already have the sensitivity turned down as much as possible and it still is happening. This issue makes an otherwise wonderful vehicle almost uunrivaled. When this happens there's no warning before the sudden braking. It also will randomly just slow speed down for no reason and with no way for the driver to stop it. Something needs to be done. Fix the system and make available a way to disable it without it auto turning back on. Im fed up.

3 incidents of same braking component. Once while exiting a parking lot, the car slams breaks so hard while accelerating that car slams to hard stop with no warning. Once while driving through an intersection brakes engaged for no reason. Once after stopping at Red light, then when moving with traffic, car stops so hard with no warning that we were almost rear ended and seat belt left marks and bottom of car seemed to hit the ground. These violent automatic breaking events are scary because for no reason or cause and no warning the car suddenly hard brakes. Fear of being rear ended or car flipping from such sudden and hard breaking. This incident has not been inspected although the car is current on all maintenance and has been recently in to car dealer for oil change.

On 5/14/2026, while driving southbound on I-95 with my pregnant wife and young daughter, my 2025 Hyundai Tucson (approx. 7,500 miles, purchased new 10/2025) experienced multiple critical safety failures. Two days prior, the heads-up display (HUD) intermittently failed to activate. On 5/14, traveling at 65-70 mph near [XXX] , the brakes auto-applied without driver input. Simultaneously, the instrument cluster and HUD went completely black, eliminating all speed and vehicle status information. This recurred intermittently. Near [XXX] , the brakes auto-applied with full force, locking all four tires and bringing the vehicle from approx. 70 mph to a complete stop on the active interstate. Two trailing vehicles spun out and left the travel lane to avoid rear-ending us. A multi-car pileup was narrowly avoided. The vehicle was taken to Pearson Hyundai in Midlothian, VA. They diagnosed and replaced a faulty wiring harness. Immediately after the repair, driving northbound on I-95 back to [XXX] (5/16), the lane keep assist/lane departure system began pulling the steering wheel into the adjacent lane without driver input, repeatedly and unpredictably at highway speed. The dealer repair did not resolve the all defects. Within a three days this vehicle exhibited: (1) total instrument cluster/HUD failure, (2) uncommanded emergency braking at 70 mph causing two other vehicles to take evasive action (3) uncommanded steering input into an adjacent lane. These failures created immediate risk of serious injury or death. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
