Known issues on the 2023 Tucson. Two recalls are on federal record for this model year. The first covers the automatic transmission fluid pump: the recall concerns the controller for the Idle Stop & Go oil pump assembly, and an electric oil pump assembly that overheats increases the risk of a vehicle fire. The second covers the trailer hitch on Tucsons equipped with an optional Mobis tow hitch wiring harness that may have been installed incorrectly, and nonfunctioning trailer lights can increase the risk of a crash. Owners have filed 195 complaints for the year and Hyundai has issued 51 technical service bulletins. The factory diagnostic and repair procedures behind each of those systems are here.
From an Idle Stop & Go oil pump check to rear harness and tow wiring work, a hybrid system fault or a scheduled service on the 2.5L, it keeps you on the Hyundai procedure and the correct specification for your particular 2023 Tucson.
Hyundai Motor America (Hyundai) is recalling certain 2023-2024 Palisade Tucson, 2023 Sonata, Elantra, and Kona vehicles. The electronic controller for the Idle Stop & Go oil pump assembly may contain damaged electrical components that can cause the pump controller to overheat.

My client lost her right eye and suffered a brain injury when an aftermarket rhinestone emblem decal from her steering wheel shot into her face during a low-impact crash with a deer. The crash left minimal damage to the front end of the vehicle, but caused the airbags to deploy, shooting the decal into my client’s head. She purchased this dangerous decoration on Amazon, and despite NHTSA notices in 2023 and 2024 telling consumers to “avoid purchasing these steering wheel decals for all vehicle
I was driving straight when a vehicle coming from the opposite direction made a left turn without yielding, crossing into my lane. As a result, my vehicle collided with the other car at full speed. However, the airbag in my steering wheel did not deploy upon impact, as it should have. My injuries have been significantly more severe than they would have been had the airbag functioned properly. I reported this issue to the vehicle manufacturer, and they opened a case and conducted an inspection. D
I was backing out of my driveway, which is on a busy street. I waited for the traffic to clear. I backed out onto the main road, which I thought was completely clear, but a car came behind me and I smacked right into him. There was no beeping from my car, and the automatic braking system did not engage at all. The rear of my car, particularly the driver's side, was severely damaged. The other car's passenger front door was badly damaged. The side curtain airbag on their car deployed and th
As I was parking my car in a parking spot going about 5 miles or less. My car surged forward at a very accelerated speed, and I ended up running into a brushed and a metal fence, which is what stopped me. There were no warnings that went off on my car. No emergency brakes, nothing.

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 ac
The car suddenly and unintentionally accelerated. To avoid going through the back of my garage, I turned slightly and hit the frame of the garage. It continued to accelerate for a few seconds until I managed to stop it. I then backed up. Again, the car suddenly unintentionally accelerated. I managed to stop it. I slowly drove it into the garage. I left it in the garage until having it towed to Planet Hyundai. I did not want to drive it in case it accelerated on the drive to Planet Hyundai. I
on 04/16/23 I got into my car and Immediately after going into drive the brakes completely failed. The car continued accelerating even after releasing the accelerator and refused to stop even while pumping the brakes. Thank god I turned into a tree and missed pedestrians. the car was totaled.

I purchased a new vehicle in February 2023. After a month and a half, I traveled to Washington DC on a pleasure trip. After my work/vacation trip when I am returning back to home all of the sudden, there was heavy smoke from the hood and eventually tried to turn off the engine but the car didn't respond, and when I tried to open the Hood in order to cool down the engine I see fire already in the engine. So, there was no intimation on the dashboard about the fire or not even an alert. Moreover, t
