On June 7th, I experienced a concerning incident involving the lane-keeping assist feature in my car while driving on Pinehurst Dr. in Aptos. As I was going around a corner just after the elementary school, I had forgotten to turn off the lane assist feature. Since there is no permanent way to disable this feature, when another car approached from the opposite direction, the lane assist system kicked in aggressively. I had slightly drifted too close to the center lane, and the system forcefully jerked the steering wheel to the right. This sudden and aggressive correction nearly caused me to hit a teenager riding a bicycle on the right side of the road. If I had only one hand on the steering wheel, the lane assist could have easily caused the car to veer off the road or collide with other vehicles, pedestrians, or in my case, the bicyclist. Although the manufacturer is aware of this issue, they do not seem to be giving it due consideration. The overly aggressive nature of the lane-keeping assist feature poses a significant safety risk and is a dangerous flaw in the system. I believe this problem needs to be addressed urgently to prevent potential accidents and ensure the safety of drivers, passengers, and other road users.
The line keeping assist system keeps on jerking the car into traffic
Lane keep assist feature is on by default and will try correct the steering even when it is going in straight line but one of the lane in road is missing or not vissible. This could be mainly in intersections. I also had an issue where steering wheel adjustment is not working due to communication box issue, they had to unplug and replug the wire between communication box and steering wheel. It also stopped in the middle if road saying electrical system failure with in two days of my leased car. It was in service center for 45 days and got my car back recently.
As per the technical specifications, The VF8 car must adhere collision safety features. But actually when we drive the car on freeways, State highways, and internal roads, these safely features never worked for me. Kindly refer the attached technical feature documents so called supported features by the manufacturer.
1) Forward collision detection doesn't work. Very rarely screen shows a pop up, but never applies automatic brakes. Especially when we were in traffic and if vehicle infrant suddenly stops. ..then it doesn't detect the forward stopped objects and fail to apply breaks 2) we need to push break paddle hard to stop the vehicle completely when car is below 10Mil/hrs speed . It feels like at lower speeds break paddle doesn't work. 3) The lane keeping assistant never worked. 4) Sometimes a car drags to one side of the traffic even when it is going at a speed of 25Mph.
Vehicle drove into traffic cones at night when adaptive cruise engaged. Freeway was reduced to two lanes and car ignored them. Pulled to side of road and car did not go back into gear. Gave errors.
Front collision sensors and lane keeping sensor do not work in direct sunlight. For 2 hours in the morning and two hours at dusk. Sensors are behind rear view mirror and they do not work when sun is at eye level.
At early morning 6am, the Advanced Driver Assistance Systems malfunction cant detect the lane on the highway. while traveling the car suddenly steering randomly and almost cause a accident twice, before i have time to turn off the system.
I was driving on the highway 87 California from the south to the north. After I changed to the furthest left lane and stay within the lane completely. I started to turn on ADAS system, as I was adjusting the desired speed, I felt the car was speeding up too much to reach my speed set up, so I decided to step on the brake to slow down the car. Right when I step on the brake, I heard a loud noise from the car, which I strongly believe the car was experiencing the conflicting command within its software. On one hand, the car ADAS want to speed up to the desire speed, on the other hand, the brake was engaged by me so it need to stop. That conflicts result my car shifted to Neutral on the highway, which I was able to drive it to the emergency lane and stop it. After the car came to complete stop, I shifted it to Park, and the car screen had a lot of errors on the screen and unable to continue to drive. Only after I got out of the car and turned off the car completely and wait 15 minutes, then I was able to start the car and drive again.
Major Issues: Vehicle unresponsiveness: Twice in 4 days, the car was unresponsive, requiring a family member to stay in rain and cold weather (very dangerous) and wait for the car to restart(extremely dangerous). Unintended rolling: Once, the car started rolling back when parked on a slight incline, requiring me to activate creep mode. Additionally, while parked in reverse, the car inexplicably moved forward even with the gear in reverse (extremely dangerous). Speaker malfunctions: The speakers were unresponsive the first two days. On the second occasion, restarting the car resolved the issue but resulted in loud noise from the front speakers. Climate control malfunction: Despite turning off the AC and fan, cold air continues to come inside from the vents regardless of settings. This is uncomfortable and unusable during winter. Heads-up display not working(extremely dangerous). Battery warning: Technician mentioned battery is weak on new cars as per my knowledge batteries typically last 10+ years. Paintwork inconsistency: The driver-side paint color is uneven, with a clear and obvious difference between the top and bottom portions. Frunk battery cover broken. Minor Issues: Manual adjustment of drive mode required each time. System automatically turns off the 360-degree camera on turn signals. VinFast navigation is slow and inaccurate. Using CarPlay, but it frequently disconnects. CarPlay connects even when the car is parked, interrupting phone calls while talking inside home. Automatic locking not functioning as advertised. Sales rep mentioned I can just walk away with a key that will auto lock which never happened. Defrost fan automatically defaults to a high speed, and hot air directly on my face. If I try to change the fan speed, Defrost disabled. So I need to drive with a hot fan speed on my face. Lane assist malfunctioning, pulling the car closer to the right/left lane instead of correcting. Occasional triangle warning appears on the screen, unsure of its mean
When in heavy fog, rain, direct light to cameras or sensor the safety features become unavailable. As soon as any of the above goes away they come back. This in my opinion becomes more of a risk driving these vehicles if the safety systems do not function properly.
