What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
A Police report was filed; however, the information was not provided. The vehicle was towed to a local tow yard. Additionally, after the tow truck driver inspected the vehicle, the contact was informed that the passenger’s side front tie rod was fractured. The manufacturer was contacted by phone and a case was filed.
I had heard a thumping noise in the front end when I would turn the vehicle. On the date of crash, there was a very loud pop noise, then loss of brakes and impact. Air bags deployed due to impact. Total loss.
Sensors and automatic brake failed. Car concerns have been reported and waiting 6-8 weeks for GMA to deem if it is eligible for an investigation. No loaner car offered despite being told NOT to drive the vehicle. No prior warnings. No one was home to drive the car. Very concerning.
My 2023 Genesis G70 has recurrent, intermittent engine power loss and stalling while driving, including on highways. The check engine light comes on intermittently and the engine can run roughly. After a stall, restarting can restore operation, but the issue recurs.
I noticed my driver head light starting to get condensation after doing further research i found it’s a common manufacturer defect especially for the g70s. I took a further look by removing my front bumper & noticed 3 cracks starting from each screw on the front of the headlight mounting.
The contact stated that while the vehicle was parked inside the garage, the contact discovered that passenger’s side headlight was cracked and there was moisture inside the headlight. The contact stated that the moisture inside the headlight affected the operation of the turn signal.
The contact stated that while driving on several occasions at various speeds, the "Turn Signal Error" message was displayed and an orange master warning light was illuminated. The vehicle was taken to the residence, where the contact noticed condensation in the passenger’s side headlight.
Lane assist was on but the car was not on cruise control. The problem was resolved after pressing the accelerator. I was not hit but the could have been a dangerous situation if someone was right behind me.
