“Takata recall. The car has about 48000 miles. 1) when driving at highway speed, brake self applies forcefully at times when passing or being passed by other vehicles on the adjacent lanes on both sides, almost creating rear-end collisions on a few occasions. 2) when resetting the cruise control to the previous setting, it continues to accelerate past previous setting (over 100 MPH) until being manually disengaged. …”
NHTSA complaint #11231361, filed 2019-07, 46,798 miles“I am unable. To drive my car anywhere. Each time I start my car. All warning lights flash like a Christmas light. It causes the car to suddenly be slowed down. Or not to go full speed? I got the recall notice in the mail 4 weeks ago. My car has been parked in the garage for four months and has been there ever since. I need my car to go to work and I don't know what else to do. I can only do so much by using the cars of families and friends, but I need my car back because it's inconveniencing them too as well.”
NHTSA complaint #11558345, filed 2023-12“For the last year or so when driving my Equus the signal lights left or right side has been working intermittently. I can go months without any issues but lately it seems to be worsening. I transport my Mom that has dementia around and its scary because it seems never know when the lights may not work at all. People drive so crazy and if its dark or light they dont see my arm out the window. Please tell me that you can assist with this issue. I inherited this car from her brother that died of cancer, this car was his dream. I'm doing all I can to keep it in top condition. …”
NHTSA complaint #11741912, filed 2026-06“Car is equipped with an air bag suspension system. There was a failure with the airbags around 18 months ( in 2016) of the car being put in service. I was driving on a hway at 70 mph w/grandkids in the car when the airgbags failed and the nose of the car immediately went down and the car started to veer. Luckily there was no other cars around me and I was able to slow down and pull off the hway. Coincidentally, I was just a mile from the dealership and immediately took the car to them and they gave me loaner car and took it in to repair under warranty. …”
NHTSA complaint #11424809, filed 2021-07“This is the e-mail that I sent to Hyundai to notify them of a serious safety issue w. Their new Equus: I wanted to alert you about a potentially severe safety issue that happened to occur while my 13 yr old son & I were examining the Equus at the charlotte autoshow. I was sitting in the driver seat, my son was sitting in the passenger seat & another couple, who we did not know, were in the back seat checking out the electronic controls. Suddenly, the passenger seat started to move forward & at the same time the seat back began to fold forward. …”
