Hyundai Motor America (Hyundai) recalled certain 2019-2021 Tucson vehicles on September 4, 2020. On December 30, 2020, Hyundai expanded the recall population, and added certain 2016-2018 Tucson vehicles. The Anti-lock Brake Hydraulic Electronic Control Unit (HECU) could corrode internally and cause an electrical short, possibly resulting in an engine compartment fire.
An engine compartment fire can increase the risk of injury or crash.
Hyundai will notify owners, and dealers will replace the HECU fuse. For 2019-2021 model years, the Electronic Stability Control (ESC) software will also be updated. Recall repairs will be performed free of charge. Owners are advised to park outside and away from structures as a precaution until the recall repair is complete. The recall began November 2, 2020. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 195.

Forward collision avoidance, Jul 1, 2026
Forward Collision Avoidance Assist is on and will not go off. Only has 16,900 miles and is newly out of warranty except for 5yr 50,000 bumper warranty. Dealer at Allen Turner says noat way they will cover this because my Vin is not listed in the latest recall. This vehicle was purchased new and has been maintained as required by manufacture . So, I am [XXX] and have purchased new Hyandais before. I do not at this time in my life have the means to fix this issue. Is there any help on this from Manufacture since this is so newly out of warranty and low mileage. I do not know what to expect as to causing a road accident and hurting myself or someone else. My phone is [XXX] and address is [XXX] Email is [XXX]. Kind regards. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Forward crash avoidance system keeps activating causing the car to brake on it's own. This was previously fixed on my car once back in 2022 and now in 2026 it is happening again. I have been trying to communicate with Hyundai regarding additional years to current recall but their not going to even though they have known for years this was an issue and included older models than their current recall. This is not a one time issue this is the second time and until fixed it continously caused the vechile to randomly brake, it's going to get someone seriously injured or killed if they don't address it.

The contact stated that upon starting the vehicle on several occasions, the message "Check the Forward Collison System" was displayed, and a collision warning light illuminated. The vehicle was taken to a dealer, where it was diagnosed that the forward-looking camera had experienced an open circuit, and unknown parts needed to be replaced. The contact stated that the failure was associated with NHTSA Campaign Number: 26V316000 (Forward Collison Avoidance). The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 69,493.
Steering, Electrical system, Forward collision avoidance, Jun 19, 2023
I've had numerous issues with my vehicle, including power steering, brakes, loss of power, and more. On a few occasions, I started my vehicle and put it into drive, only to find that the power steering hadn't disengaged. This led to near collisions, such as almost hitting another vehicle while backing out of a parking spot and nearly running into a wall. I've reported these issues to Hyundai multiple times, but the dealership can't reproduce the problem, despite having recordings of the incidents. I've also experienced delayed release of the electronic e-brake and it feeling like it hadn't fully disengaged. In a recent event, with passengers in the car, the e-brake auto-engaged while driving downhill, bringing the vehicle to a halt. I had to manually disengage it and restart the vehicle to resume normal operation. I contacted Hyundai customer service again, but I'm still waiting for a formal response. Other symptoms include loss of power during acceleration, engine starting issues, stuttering, and occasional burning smell from the brakes. Despite my efforts, Hyundai hasn't provided any solutions to these problems. I drive with multiple passengers in my vehicle all the time, including children and have major concerns regarding any of these issues happening, let alone while I am driving at higher speeds or with someone else driving my vehicle.

Forward collision warning is set at "early", but I only get 1 out of dozen incidents where I feel the warning should be triggered. Often I had to hit the brake hard enough to cause chest pains for me & my passenger. So, the injury below is a minor one for now, but may easily become quite extensive.

I BOUGHT A BRAND NEW 2021 HYUNDAI TUCSON ON 1/1/2021. I FOUND OUT ON 1/10/2021 THAT THERE WAS AN ACTIVE RECALL ON MY CAR. AFTER LOOKING THROUGH THE LAWS IT STATES THAT A CAR DEALERSHIP IS LEGALLY NOT ALLOWED TO SELL A CAR THAT HAS AN ACTIVE RECALL. WHEN I CALLED THE DEALERSHIP THEY VERIFIED THAT THEY RECEIVED THE RECALL INFORMATION FOR THAT SPECIFIC CAR ON 12/30/2021 BUT PROCEEDED TO SELL IT ANYWAYS. I AM VERY UPSET THAT THIS HAPPENED AND NOW I HAVE TO TAKE TIME OUT OF MY DAY TO TAKE THE CAR INTO THE SHOP FOR THEM TO FIX THE PROBLEM ON A BRAND NEW CAR THAT NEVER SHOULD HAVE LEFT THE SHOWROOM FLOOR.
