Vinfast VF 8 lane assist problems

Filed Apr 2, 2026 · Driver assistance · CA

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 / the federal safety agency 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 the federal safety agency 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.

For approximately two weeks, this vehicle exhibited intermittent, uncommanded steering wheel "tugs" and erratic Lane Keeping Assist behavior. During a U-turn on 1/25/2026, the vehicle struck a curb. While I cannot definitively isolate driver input from system input during the maneuver, the vehicle immediately entered a "fail-safe" state, triggering a cascade of specific error codes: Electronic Stability Control (ESC) Fault, Front AEB Unavailable, Highway Assist Inoperative, and Intelligent Speed Adaptation Inoperative. These errors are directly tied to the ADAS/ADCU systems currently under the federal safety agency Recall 25V559, which identifies a defect where the system provides "sudden steering inputs that are difficult for the driver to override" during turns. The dealership VinFast Lisle is acknowledging these recall-related errors are present but is refusing to cover the resulting physical damage, quoting a repair cost of over $2,100 + taxes. I am reporting this because the manufacturer should not be able to dismiss a collision that occurs while a vehicle is actively suffering from a known, federally-recalled steering defect. I request that the federal safety agency investigate whether this hardware damage is a consequence of the software failure.

Lane keep assist is not able to detect curves and bend, and it tries to pull on the opposite lane instead keep it in the center of the lane. It is hard to override the steering input.

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.

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.
