NHTSA complaint #11755586 — an unverified report by a vehicle owner.

UNKNOWN OR OTHER

The car was purchased on [XXX]. On [XXX]—only six days after purchasing the car—it failed to accelerate through an intersection while turning left in front of oncoming cars. Less than a week later, on [XXX], the car again failed to accelerate as it slowed down entering a rotary on [XXX] . The same thing happened again on [XXX] as it was driven out of the Savannah Bend Marina, turning left onto [XXX] , and yet again on [XXX] while driving around a traffic circle on [XXX] . On [XXX], the car once again failed to accelerate when attempting to clear an intersection on [XXX] Pooler, a Savannah suburb. On [XXX], after starting the car in the garage, it obviously had a problem running while idling. Backing out of the carport and pulling out onto the street, it barely responded. Even after the accelerator was practically floored, the car would go only about 35 miles per hour. On [XXX], the car yet again delayed in accelerating while turning left onto [XXX] from [XXX] . As it turned left and the accelerator was pressed down, the car slowly inched forward for a few seconds before finally accelerating and clearing the intersection, barely averting a collision with oncoming traffic. The dealership has had multiple attempts to repair the defect, but it has been unable to locate or remedy the defect.

VEHICLE SPEED CONTROL

While driving at highway speeds (55–73 mph), the vehicle has repeatedly and unexpectedly applied the brakes on its own and on at least one occasion experienced a loss of power. These events occurred without any vehicles, pedestrians, or obstacles present, and without any driver input. Road and weather conditions did not warrant braking. On multiple occasions, the vehicle suddenly decelerated while adaptive cruise control was engaged, then immediately re-accelerated back to the set speed. This created a serious risk of being rear-ended or involved in a high-speed collision. On one occasion, the vehicle experienced a loss of power while driving at highway speed, requiring immediate driver intervention to avoid a dangerous situation. These incidents make the vehicle feel unpredictable and unsafe to operate as intended. I regularly transport family members, and these failures place my safety and the safety of others at significant risk of serious injury or death. The vehicle has been inspected by an authorized Genesis dealership on two separate occasions. Despite extended road testing, the dealership has stated they were unable to reproduce the issue and no permanent repair has been performed. The manufacturer has been notified, and the defect remains unresolved. No warning lights or messages were present prior to the incidents. The failures occur suddenly and without advance indication.

SERVICE BRAKES

I am submitting this report to document a serious and dangerous safety defect involving my Genesis G70. Note - Your system pulls my VIN as a G80, I own a G70. On two separate occasions, the vehicle applied braking without driver input and abruptly veered to the left, despite there being no obstacles, vehicles, or road hazards present. During the first incident, the vehicle was operating in Comfort mode with Lane Assist enabled. During the second incident, the vehicle was operating in Sport mode with Lane Assist disabled. In both cases, the braking felt as though it was applied to the front-left wheel, causing an immediate and forceful deviation of the vehicle to the left. Both incidents occurred while the vehicle was traveling at speed and required immediate corrective action. I was forced to divert the vehicle onto the shoulder to avoid a potential collision. My family was present in the vehicle at the time. Had there been a vehicle in the adjacent left lane during either event, a collision would have been unavoidable. No warnings, alerts, or visual indicators were displayed prior to or during either incident EXCEPT late / after or during about Checking Lane Safety Warning There were no objects, lane intrusions, or traffic conditions that would justify autonomous braking or steering intervention. I am reporting this issue as a critical safety defect that poses a serious risk of collision, injury, or fatality. I am also reporting the issue to my authorized dealer, Global Auto Mall (Route 22, North Plainfield, NJ), for immediate inspection and diagnosis. I am aware of other similar reports involving this behavior and believe this issue warrants investigation. I am submitting this complaint to the National Highway Traffic Safety Administration to document the defect and to help prevent potential injury or loss of life.
