The car was working perfectly fine I drive it for work all the time and one day it started shaking weirdly. A couple days later the check engine light turned on. It was throwing the code that was pointing to "misfiring in the 3rd cylinder" We changed all the spark plugs, 3rd cylinder coil pack, and switch the coil pack to see if it would say a misfiring in a different cylinder. We then took it to a mechanic saying that it is the high pressure fuel injectors and that he has seen this problem with other Hyundai Tucson around the same year as us and that there was a bulletin on it.

Under Hyundai Recall 290, the dealership permanently removed the functional trailer light wiring harness and replaced it with a nonfunctional rubber dust cap. A Hyundai case manager informed me that a replacement harness is "in development," but official NHTSA remedy filings show the cap is the final remedy, resulting in the permanent loss of a factory feature I paid for. The removal of towing functionality without a clear timeline for a safe replacement parts remedy constitutes a failure to properly correct the vehicle defect.

The right rear shock absorber failed and was replaced under warranty at approximately 22,000 miles. The car was making noise, the shock was leaking, and not working properly. The dealer admitted to problems with rear shock absorbers failing at low mileage on Hyundai Tucson Hybrid SUVs 2022 through 2025 Tucson Hybrids. The left and right rear shock absorbers are the same part number so we now expect the left side to fail but the dealer will not replace the left until it fails.

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. During their inspection, they found that the airbag had since deployed. However, my vehicle was transported off a steep hill and moved to multiple lots before the inspection, any of which could have triggered a delayed deployment. Despite this, the manufacturer has refused to accept liability. Because the airbag failed to deploy at the time of impact, there was no buffer between me and the steering wheel. This resulted in excessive force against my chest from the seatbelt and direct impact with the steering wheel, leading to more severe injuries. There were no warning lights on in the vehicle before the crash, nor were there any recalls related to this issue at the time of the incident.
