2023 VinFast VF 8 Complaint Log

The contact owns a 2023 Vinfast VF8. The contact stated that while reversing into a parking lot, the vehicle unintendedly accelerated. The contact stated that while reversing, there was no warning light illuminated or safety features activated, causing the vehicle to crash into two other vehicles. The rear end of the vehicle was damaged. The vehicle stopped after crashing into the other vehicles. No property damage was reported. The vehicle was towed to a tow yard. No warning lights were illuminated on the instrument panel. A Police report was not filed. No injuries were reported. The dealer was not notified of the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 7,000.

The vehicle exhibits a severe, structural inability to retain its factory suspension and steering alignment specifications under normal driving conditions, creating a severe tire blowout and safety hazard. At approximately 8,400 miles (January 2025), the dealership documented that the alignment was heavily out of specification. At approximately 9,400 miles (February 2025), a certified third-party shop corrected the vehicle back to perfect factory specifications. Less than 9,700 miles of standard city driving later, at approximately 19,100 miles (May 2026), a dealer inspection revealed the vehicle's alignment geometry had completely shifted out of specification across three separate wheels (Right Front Toe, Right Rear Camber, Left Rear Toe). This rapid alignment failure dynamically scrubbed the front steering tires completely bald down to the internal metal structural cords/threads, creating an immediate, severe safety hazard on the road. The vehicle's inability to hold standard parameters points to a defective suspension tracking design or components incapable of supporting the vehicle load. The dealership refused to cover this mechanical failure under warranty, forcing an out-of-pocket tire replacement expense. A formal corporate escalation case has been opened with the manufacturer.

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.

While driving at approximately 8:00 AM in active traffic, the vehicle suddenly would not accelerate beyond approximately 20 mph. Warning messages appeared on the dashboard stating “Electric Motor Power Reduced” and “Driver Monitoring System Inoperative.” The vehicle lost normal propulsion power without warning. This occurred in the middle of the roadway and created a serious safety hazard, as I was unable to maintain the speed of surrounding traffic. Vehicles behind me had to slow abruptly, increasing the risk of a rear-end collision. The vehicle is currently under warranty and has been taken to the repair facility multiple times, including for prior safety-related concerns. The most recent repair visit involves diagnostics and/or a software update; however, the root cause has not been clearly explained, and the safety of the vehicle has not been formally confirmed in writing. Given that this incident involved sudden loss of propulsion in traffic, I am concerned about the reliability and safety of the vehicle.

See attached document for complaint.

The contact owns a 2023 Vinfast VF8. The contact stated that while his wife was driving 30 MPH, the vehicle inadvertently lost motive power and came to a complete stop in the middle of the roadway, where the vehicle failed to restart. No warning lights were illuminated. The vehicle was towed to the dealer and the vehicle was repaired but the contact was not provided a diagnostic report nor the repair information. The vehicle was repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was unknown.

The 12v battery when car was purchased was defective. This caused the car to suddenly die. As per the sales manager where car was purchased heat disables the car from running properly.

Car steering veered to left. Car died would not start again. Info center and 12v battery died and stopped working. Was unable to restart unsafe vehicle.

The contact owned a 2023 Vinfast VF8. The contact stated that while driving at 35 MPH, another vehicle driving on the opposite side of the road aggressively proceeded into the front passenger side, causing a t t-boned collision. The impact caused the other vehicle to be pushed back to the opposite side of the road. The contact's vehicle then veered to the right and crashed into two more vehicles that were parked. The vehicle then came to a stop after the crash. No warning lights illuminated. The driver’s and passenger’s side air bags did not deploy. There was no property damage. A police report was filed. The contact sustained injuries to his hand, neck, and back, and his 2 children sustained general body pain. The contact and his children were still visiting the doctor for treatment. Injuries to the other vehicles were unknown. The vehicle was towed to a collision center, where the vehicle was deemed destroyed. The manufacturer was not notified of the failure. The dealer was notified of the failure. The failure mileage was 3,391.

I had several alert messages for weeks and after a service call, they told me that they were no issue. with all this alert messages it is impossible to let my Daughter driving the car. it is too risky.

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.

On [XXX], [XXX] both my daughter and I were driving on [XXX] going East by [XXX] . We were rear ended by a driver under the influence. Upon impact the driver front seat and passenger front seat reclined down. We are unaware if this is a safety issue. However, we feel that we sustained additional injuries because of the seats reclining . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When do you go does not detect lanes violently moves the steering wheel to try to maneuver you back into a lane. I’m constantly turning this feature off because it has posed a risk of crash on multiple occasions

When regenerative braking is active brake lights do not turn on causing vehicles behind you to come extremely close. The vehicle has extremely strong regenerative breaking. That should activate the brake lights.

The anti break having issues. Sterling controls having issues Supsention having issues

I have had nothing but brake and suspension problems with my 2023 Vinfast VF8. The vehicle has been to the dealer on three occasions because of brake and suspension noises which prompted the dealer to replace the entire suspension system. However, my concern is with the vehicle's brakes. Under low speed turning with no brakes applied, the vehicle made a metal on metal grinding noise. The vehicle was in the dealer twice for this problem. The first time they put updated brake pads on the vehicle and let me know that the original pads were too thick. The problem continued and the vehicle was taken back to the dealer a little over two weeks ago for the same problem. This time they sanded the surface of the brake pads to avoid them from rubbing against the rotar. The tech at the dealer told me that he beleives the issue may be that the brake caliper does not open wide enough to allow the pad distance from the caliper. Their solution is to sand the pad down. One, is this safe, and two, what happens when the car needs new brake pads, is the dealer going to cover the cost to continually shave the pads down for the life of the vehicle.

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.

I was driving on the Highway and when I stopped at a red light the vehicle stopped working. I was not able to put it in neutral to be able to move it to the side of the road. I had several warning messages while i was on the phone with 911. I was lucky enough that police came to assist me within minutes since I was at an intersection of two highways. I could've been killed or caused a bad accident. I called Vinfast to check the problem and they never transfer me to the service department. I explained the problem and they just told me that if it happens again they will consider it. But since the vehicle restarted after 20 minutes there was no reason to check it. I asked to talk to a supervisor but the customer service representative refused. She just told me that she was making a note about it. This was a very dangerous situation. My life and the life of others were at risk. I have pictures and short videos showing the car in the middle of the highway and there is a call made to the 911. Thank you

Lane keep assist feature is on by default even with new software updates. when you merging to turning lane at intersections even with the turn signal is on, the car will try stop you merging into the turning lane.

Vehicle drive system fault: This issue has happened to me 2x in my personal car and 1x in the loaner vehicle that Vinfast gave me. When this happens, the vehicle shuts off. You can’t put the car in drive or reverse. You have to leave the car, wherever it is, walk a good distance away& wait for about 15mins. The first time, I was pulling into a spot at a grocery store & and car died in the middle of the aisle. I was blocking all traffic. Luckily after 4 mins the car was able to go into N and I got pushed into a parking spot. The second time was with the loaner car, I started to back up and the car died. This time, I had to walk in the rain to a store down the street and wait for the car to “disconnect from the key fob” and wait 15 mins. The third time I was in my personal car and I was moving. I slowed down to make a turn and the car slammed on the brakes and died. For me, this is a huge safety issue. I’ve been driving for over 25, had many cars and never had issues like this. I’m not always in a safe location where I can get out and leave the vehicle. Also, ever time I get into this car there is a new error message, for example. The AES system turns off when facing the sun . I’ve reported all of this and documented everything. I feel unsafe in this car. The dealer said “ the driver fault will happen when you put it in gear too fast”. I’ve driving like this for 25 years and I’ve never had a car turn or and leave me stranded. I don’t trust this vehicle

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

While I was driving to work, the car started to lose power all of the sudden; I had to exit the freeway, as soon as I was off the highway, the car no longer moved. I called customer service they indicated that I should try to reset the car (which I did) and was able to drive the car again but with a lot of warning signs. I think it is a safety concern because I could hit or get hit by another car while trying to pull over. Customer Service told me to expect a call from the Service Center but at this date they haven't call me yet.

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.

vehicle would not go into drive. car immediately stops and I wasn't able to get the car into drive or reverse. Had to be towed to the service station with no cause determined.

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.

The contact owned a 2023 VINFAST VF 8. The contact stated that while driving at unknown speeds, the steering wheel automatically maneuvered to the right direction, however, the contact was able to regain control of the steering wheel and maneuvered into the correct lane. The contact stated that the failure recurred where the lane assist was turned on by default and it would automatically move the steering wheel. On another occasion, the contact stated that a coworker was driving at unknown speeds with his family, the vehicle crashed into a pole, then a tree where it came to a stop. The vehicle then caught on fire. The contact mentioned that during the impact to the pole, the pole fell down. The air bags deployed. There were 4 occupants during the crash, the driver, the front passenger occupant, and two children seated in the rear of the vehicle. All occupants were deceased. The contact was concerned that the failure recurred while the coworker was driving. The location of the fire was unknown. There was a police report was filed. The vehicle was towed to the police department. The manufacturer was made aware of the crash and a case was opened. The failure mileage was approximately 1,400.

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.

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.

Driving 80+ car suddenly loses power . Says electrical system fault and coolant fault. Stranded on freeway in fast lane. Takes 9 resets and 1hr before car goes back to nirmal

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.

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.

The contact leased a 2023 Vinfast VF 8. The contact received notification of NHTSA Campaign Number: 25V559000 (LANE DEPARTURE). The contact stated that while making a turn, the vehicle jerked, and the steering wheel unexpectedly became difficult to turn. In addition, the vehicle made wide turns. No warning lights were illuminated. The contact stated that on a separate occasion, the A/C failed to function as intended. The vehicle was repaired; however, the failure persisted. The contact stated that on a separate occasion, after the vehicle was charged at the residence, the charge was drained after two days. Most recently, the driver’s side door failed to lock as intended. The contact closed the front driver’s side door; however, the door opened independently and remained ajar. The vehicle was taken to an authorized mechanic; however, no cause for the failure was found. The contact stated that the failure persisted. The manufacturer was notified of the failure. The failure mileage was approximately 5.

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.

First time was end of May and the car went into park while driving down the road and stayed stuck in park. Could not change gears. Eventually the entire car shut down and even hazard lights did not work. Second time I was parked at my office and when I got back to my car, it again would not shift out of park. It would not move into any gear.
