Example complaints

Transmission and drivetrain: “I was driving on the highway and my transmission due to a failed transmission service done to my vehicle caused my vehicle’s transmission to overheat a blowout my transmission cooler and mix coolant and transmission fluid unknown to me because of a clogged transmission cooler line improperly flushed instead of replaced by the Patrick Hyundai dealership there could’ve been and electrical fire or a crash due to these things.”

NHTSA complaint #11748611, filed 2026-07

Engine: “I am reporting a severe vehicle safety hazard involving a sudden loss of motive power and extreme thermal failure on my 2012 Hyundai Equus Signature 5.0L. In July 2022, at 88,845 miles, an authorized Hyundai dealership replaced the transmission under a factory warranty event. Rather than replacing the transmission oil cooler assembly—which was contaminated with heavy metal shrapnel from the original mechanical breakdown—the servicing dealer chose to only flush the lines, creating a latent fluid restriction. …”

NHTSA complaint #11749120, filed 2026-07

Suspension: “My vehicle sways like a boat side to side no matter my speed, but on the highway it almost feels like I'm losing control. I have taken the vehicle to the dealership and after having it for 4 weeks they returned my vehicle back to me not repaired and no answers to why the issue started. I was told they were requesting an Hyundai field engineer to come out to inspect the vehicle but I have not heard from them in almost 2 months.”

NHTSA complaint #10676847, filed 2015-01, 31,000 miles

Air bags: “Following a slip on the road I am the victim of an accident on the edge of a Hyundai santa fe. The car struck the mountain, but the airbags failed to activate in the accident resulting in a frontal impact, which caused me serious injury. Why the airbags are not triggered ?? The car made several rotations and suffered irreversible damage and despite everything the airbags were not triggered.”
