2023 Vinfast VF 8 driver assist problems

LANE DEPARTURE

See attached document for complaint. I am writing to file a formal complaint regarding serious delays and lack of communication surro ding a safety recall repair for my VinFast vehicle. I received an Important Safety Recall Notice from VinFast Auto LLC regarding Recall Notice VPAC 379 / NHTSA Recall No. 25V559, involving a software update to address issues with the Lane Keeping Assist {LKA) system. The notice states that this update should take approximately five (5) hours to complete. Despite this, I have been waiting for over three months to obtain an appointment for this recall service. When I went to the dealership today to drop off my vehicle, the staff could not provide any estimated timeframe for how long the repair would take. This is especially conce, ning because during a previous visit, my vehicle remained at the dealership for nearly one month. When I asked the employee how long the recall update would take, I was told they would not know until they began the software update process. I was also informed that once the update starts, it cannot be stopped. This was not communicated to me in advance, and I was left without any clear plan for transportation or support.I had to leave because I need to pickup my kids from school. I cannot find any appointments now? I asked how I was expected to get home or whether alternate transportation such as an Uber or loaner vehicle would be provided, and I was told that there was nothing they could do. I find it unacceptable that after waiting months for a safety recall repair-one that the manufacturer estimates at only five hours-the dealership is unable to provide a reasonable timeline or any assistance for customers who depend on their vehicles for daily transportation. I respectfully request that NHTSA review this matter, as consumers should not face excessive delays, unclear repair timeframes, or lack of transportation support when attempting to comply with an important safety recall. Thank you for your attention to this issue.

Got my car back from service a couple months ago and it is still performing with errors. While driving in a specific lane on the freeway the car would try to pull my steering wheel to the other lane. VinFast stated an update is all is needed and the problem still is occurring. This car is dangerous. One example of this is the Pleasanton California incident.

I purchased my Vinfast VF8 in March 2023 as one of the first to be delivered. Unfortunately, on the first day of receiving the car, I encountered some issues. The fault sensors went off repeatedly, particularly during a rainy day. The car currently has 9600 miles on it, and it has been driven from San Diego to Irvine around 3-4 times to be serviced for issues associated with the functionality of the VF8, with one of those trips being to a repair facility in San Francisco. Issues that have been addressed include software updates, blank driving screen which occurred on three occasions repaired with a nationwide recall repair, brake repairs, AC replacement, sensor malfunctions, and hood latch issues. Records of these services have been diligently maintained as evidence of the necessary repairs. The next service appointment has been scheduled for September 2024, as it was the earliest available slot when the appointment was made in July. One recurring issue I've experienced is with the lane keep assist, which has been continuously faulty and almost caused several accidents while on the freeway. I brought this issue up to my service technician, who informed me that other Vinfast VF8 owners have reported similar problems. While the technician explained that the issue with the system is its sensitivity, I have found it necessary to turn the feature off before I start driving, to avoid close calls. Additionally, the car's front bumper has paint defects on the corners closest to the fenders, on both sides. On two separate occasions, the car turned off while I was driving and displayed sensor faults. I have documented the last incident with my cell phone as proof. During that occurrence, it took over 45 minutes to an hour to get the car restarted and I had to call a tow truck through Vinfast. The vehicle has been serviced more than expected for a new car with such low mileage, both in Irvine and San Francisco.

While driving this vehicle, the steering would take control and pull me to another lane at times. While turning or merging into another lane, it would auto correct and steer me into the lane I’m not steering into causing me from losing control of which direction I’m going into. A hard pull of the steering wheel would try to auto correct. Car automatically turned off on me while on the freeway losing power to the whole car. They said an update to the car is all is needed. This car is unsafe and needs to be recalled from the road before another injury occurs.

The lane assist feature repeatedly comes on randomly and has almost caused several accidents while I was driving. Specifically, I was driving on the freeway today in moderate traffic and the emergency lane assist warning flashes on and the car begins to jerk the steering wheel. It caused me to try to correct this and almost caused my hitting the car next to me. There are warning lights that repeatedly just come on without there actually being an issue. The roll back feature works randomly and has almost caused me to hit the car behind me. I have had Vinfats out to my house three times already regarding problems with the software, safety issues, and inability for the car to come on at all.

Lane keep assist will intermittently trigger while driving straight. After having this happen several times, I now disable the option at the start of every drive. Lane keep assist module will trigger a fault and restart mid drive despite being turned off prior to driving. This is in a drive by wire vehicle in which there is no direct connection between the physical wheels and the steering wheels. This has happened 3 times to me, and once to my wife. It has happened on my neighborhood streets going less than 20 mph, and it has happened on highways going 65 mph. The modules on the vehicle will intermittently, but frequently fail. The notification of various modules failing only appears on the center console screen and lasts for less than .5 second. There is no log available to the owner/consumer for prior failures if the system is able to "recover". The only way that I was able to discover this behavior by the lane keep assist module is because 2 systems had failures, then cleared and the "feature" was suddenly active in the middle of a drive. I do not know what the first system that failed was, by the time I looked down it have changed to the lane keep assist module. The vehicle has aprox. 6000 total miles on it as of the most recent incident. All other incidents happened prior to that mileage. Vinfast customer service is happy to take reports and tell me that their vehicle service department will get in touch with me. There have been no attempts to contact me by the vehicle service department, and the company does not allow customers to directly contact the vehicle service department.

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.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

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.
