Battery wont charge and non stop Critical Faults

[Chris Gerrick]

I have had my VF8 for 6 weeks and I knew this was going to be a journey, however this is even more than I thought. Charging has been a big issue. 5 1/2 hours on a 220 plug to get 12% increase of battery. 5 1/2 hours will charge my Tesla model s from 30% to 90%. Same plug. We have been waiting for a software upgrade for 4 weeks to resolve every system showing faults. I drive 1 mile, regenerative breaking fault and it turns off. when going down hill with regenerative braking on standard, I get a fault and regenerative braking is reduced. AEB faults, battery faults ( you have to park and reset the car to continue), motor faults and the car wont go into gear and you have to reset the car. Cant save ANY settings in the car. Every time you get into the car, the air is set to 87 degrees and the fan is on 5. Cannot disable lane assist and even when I do, it tries to take control of the car. Basically none of the safety features are available while driving. Apple car play doesn’t work. No home link for garage doors or gates codes even though the manual shows an app. Service has been to my house 4 times totaling more than 10 hours. Great guy and he provides me work arounds until the software is corrected but he doesn’t know when that be. My wife, who wanted the VF8 while we wait for the VF9 (yes we have 2 reservations) took my Tesla and wont drive the VF8 because she doesn’t feel safe. I have had 3 different personal concierge, but they have all disappeared. I hope Vinfast can fix this car ( though I really want my Tesla back from my wife) as there are things I do like about this car and some advantages over my Tesla, but if I can’t charge the car, I can’t drive the car, then what’s the point?

Let’s be honest. I was contacted yesterday and was told you “have a fix for all of the issues and you need to take the car back to complete all of the repairs”. I was then told there are no loaners available so you don’t know when the issues will be resolved.

Hi Chris! To give you an update on your case, our technicians currently have a game plan to tackle the problems found with your vehicle. A loaner vehicle is also being prepared for you as we speak. A representative from our Service Center will reach out to you soon to bring your car in for service. Please keep an eye out for further correspondence! Thank you for your patience!

I empathize with you man. The lane assist issue alone should ground the car and get you a loaner. The lack of saved features like climate control is just unacceptable. Hope that’s an issue for just yours and not how the software was released.

I remember when I got my car I was messing with all the setting and stuff like a kid in a candy store. I got my car on a Wednesday or Thursday. On Saturday mid-day got the never ending warnings that all the safety features were pretty much messed up. I could still drive the car but none of the safety features would work. I called tech support or tried to guess what this was before they had a 24/7 support line lol. So if you didn’t need a tow they would try to put you thru to their tech team that would never pick up the phone. Then once it pass working hours guess what they not their on Sunday so you have to wait til Monday.

The best way to reach someone is really thru the online chat system on the website.

I did get a tech to come out on Tuesday fixed the car from all the warnings, replaced the 12V battery as my car pretty much died on Sunday from the car trying to continuously reboot or restart. Tech was nice told me my car was confused lol.

Next I still get warnings off and on occassionally they pop on then go off. So I do not bother. HAd tech come this week for faints sounds in the rear of the car. Tech believed it to be the brake pads rubbing the rotors as it is a new car and im like well that does make sense but he put in a request for some new parts to have the pads replaced and maybe the rear rotors.

Then was a heater issue where it will not get warm air thru the system unless putting it all the way up to 90. Tech did say he talked to the tech department and said that is a software setting that will be changed in the update (whenever that comes out) [I have had 1 update I am on FRS9.5.9.2] I have no idea what that was for as they did not leave any notes that can be viewed on the display or anywhere.

I have had some issues charging but I just had to disconnect and reconnect and it worked on the Volta Free lvl 2 charging. I only use lvl 1 right now but plan on putting in a lvl 2 charger.

I also have issues with all the settings keep getting reset and they said that will be fixed on a software update.

Hi Scott Davis! I am really sorry to hear that you experienced some issues with your VF8. We will continue following up with you regarding the hardware problems that you are facing; while the rest, as you mentioned, are indeed going to be taken care of with the next Over-The-Air update to the firmware. I am really excited for this update as it is expected to help resolve multiple existing problems that are hampering our customers’ experience with our products. We will let you know as soon as we have any news to share. Again, thank you for choosing VinFast!

This is very helpful. Thank you. The Service team has been great but without software updates, there is little they can do to resolve the issues other than provide workarounds to some of the bugs. They are currently looking into the squeaking / groaning noise in the rear end of our car.

I agree, release notes for the firmware would be nice.

For anyone curious I was told yesterday that the next software update will come on May10. They said this should fix a lot of the known issues. I also figured the update would come after the shipment arrives next week as well. So they are prepped for sales in June.

Update:

Service came and picked up the car and provided a loaner. I was requested to provide the list of issues that I am seeing, which I did and they are looking into the car.

Interesting findings with the loaner:

1. In my car I am unable to get my phone to automatically connect to the car. It says it’s connected but I always have to go to setting on my phone and force it to reconnect and then bluetooth will work, but apple car play will not connect. In the loaner I was able to add my phone and car play started. Now when I check the car, it starts automagically under the Vinfast profile.

2. The climate settings in the loaner car remember the temperature and fan settings the last time I used the car.

All this has me thinking that there is a profile issue rather than a software issue for some of these things but we will see what the engineers say.

Fingers crossed.

What are the things that you don’t have it in Tesla and have them in VF. How is the drive compared to Tesla? Can you also compare the build and material quality of Tesla and VF8?

Hi Ramakrishna,

A few main differences between Tesla and Vinfast are available Apple Carplay on VinFast Cars, Hands-free power liftgate, a panoramic roof that is able to open, and most importantly our 10 year warranty. The drive compared to Tesla is very similar, both are extremely smooth and offer great performance, However, it’s worth noting that the driving experience is subjective, and different people may have different preferences when it comes to factors such as acceleration and handling. In addition to comparing quality, having panels gaps and issues that needs to be serviced is very common for new Tesla owners on delivery day. Our fit and finish has been much better and we are always striving to improve quality control on all our vehicles. Also, for our VinFirst reservation holders, we include VinFast Smart Driving for the lifetime of the vehicle, and a free trial for one year for our Charged Up Reservation Holders.

I hope this answers your questions!

Except the 10 year warranty the other features mentioned are nice to have features but not must for many. May be must have for a premium vehicles. When I looked at various online video reviews about cheap plastic material, I am not sure if VF comes under a premium quality. Driving experience, acceleration and handling – I would like to know from the actual owners who owns both Tesla & VF, because I bought Tesla Modal Y recently and am very happy with its overall performance and handling. I booked VF9 Plus and not expecting it in near future with the price tag that is within my budget range the way the current price range is set. If charging, mileage, lack of charging stations within reasonable distance, price for kwh, frequent warnings or troubles on the road are not well within the range comparable to other cars, no car can be called a reliable premium car. Pricing it as a primum car with all these shortcomings makes people think twice before even approach the car to take a look. Hope you guys consider these advices and set your pricing accordingly. You guys are no way near to compete with Tesla, or even Hyundai or Kia at this stage. Only way to start attracting people is set correct price, and focus on building infrastructure on the road for charging. And mileage is another major thing that people look at. I still want to keep my VF9 Plus reservation and plan to buy one if everything seems falling in place accordingly.

If you recently got a Tesla the performance, range, charging speeds, software and so on will be hard for you to adjust to. Tesla acceleration is much quicker even for just the standard editions. So if you going to compare to Tesla then you will be disappointed

We’ve had our VF8 for about a week now. Like some of the other owners, we can’t get the car to charge completely. We’ve had to take it over to a high speed charger near my office and see if it will get more juice pushed into the batteries. The screen on the car went blank, i.e. dark the other day and nothing works when this happens. The turn signals don’t work; the charge port door doesn’t open; the back up camera doesn’t work……it’s almost like someone just pulled the plug on the car and it is very unsafe to drive when this happens.

When the car was delivered, there was no placard or notifications on who to call in case of an emergency. Really a stupid oversight on VinFast’s part. When the screen is off, the access to the owner’s manual doesn’t exist. Had to call the showroom to get the service dept phone number. Of course, this all happened on the weekend and service was scheduled to come out on Monday morning which they did. Two very knowledgeable service guys came out and determined that the car was in much need of software updates but didn’t know when that was going to happen. The noise coming out of the rear of the car was because of faulty brakes—–the car is brand new and had fewer than 100 miles which, apparently, has happened to some of the other cars that have been delivered.

New parts are being ordered but didn’t know when they would be available and once here, they would come out and bring a loaner car. In the meantime, the car is sitting in the car while VinFast tries and figures out how to correct all of the software and parts issues and I’m make lease payments on what could very well turn into another Yugo or Bricklin. I’m wondering if there is anyone at corporate who is in a decision making role who really understands how screwed up these first deliveries have been on this car??? Are they all driving Tesla’s because their Vinfasts aren’t ready to be on the road yet???

I can’t wait for the JD Powers initial buyer’s survey to come out or the leading automotive press gets a hold of these cars.

The fit and finish on the car is acceptable and the features are interesting (if they actually worked). Time will tell if they can get this car really working as promised. I guess it is good that California still has the Lemon Law in place because if we have to call service 3 or more times to come out and fix these same issues, the car is going back.

What a frustration must have been for you. It shouldn’t never have happened regardless of how good Vinfast post-delivery services are.

Hi Leon Rosen!

Thank you so much for choosing VinFast! We appreciate you reaching out and giving us a chance to resolve the issues you’re encountering with your VF 8. We received your report regarding some of the afformentioned issues over the phone and have been hard at work to help you get back in the driver’s seat as soon as possible. In fact, we just got word that the parts that were ordered for your car have arrived at our Irvine Service Center. A representative will reach out to you very soon to schedule bringing your vehicle to the Service Center where it will be taken care of by our best technicians.

As for your concern with the turn signals, charge port door and the back up camera, we’d love to learn more from your perspective, so please do not hesitate to reach out to us at 1-833-503-0600. Ideally, we will address these issues while your car is with us at Irvine so it can be returned to you in perfect working condition.

Here’s an update. The service department of VinFast is incredibly on top of the situation. They came out on Monday as promised with two techs. Drove the car back to their service center and promised to have it back by the early afternoon which it was.

5 stars for the service team which includes Victor and Chris Pantages. Their immediate follow up and current notifications took some of the sting out of the faulty car issues that happened earlier.

Let’s hope they can improve their pre-inspection delivery processes and not “burn out” their excellent service team!

Update after 7 Months:

VinFast Promised to fix all of the issues however, as of today we still cannot charge the car reliably.

• The constant faults of the safety equipment: see attached photos
• Unable to charge the car at home.

• Charging fails every 10 minutes

[Natalie Ly]

• Apple Play has never worked => Apple CarPlay has been working for me since pick up. With 9.6.0.3, Apple CarPlay loads even faster than before. However, 1 complaint is Carplay Apple Map doesnt display turn by turn on HUD and doesnt narrate directions anymore. prior to this, Carplay Apple Map displayed directions on HUD and also narrated.
• The 360 cameras don’t work => Mine has always worked. I usually wait till camera icon fully loaded before shifting to Drive or Reverse. I know an owner whose 360 cam was messed up, so technician has to re-calibrate for it to work.
• The driver door handle unlock button doesn’t work => I always use this button on driver’s door handle to unlock with no issues.
• The car rolls backwards on hills and there is a delay in the response of the accelerator to catch the car. We are worried we will hit the car behind us => To avoid this, I always turn Creep on mode and step on brake. My previous ICE car had hill assist kick in very early on, so i never had to hold on to the brake while on steep hill. With VF8, i now turn on Creep mode and hold on to brake. yes sucky but definitely something can be improved upon.
• The climate control settings do not work => with 9.6.0.3, climate setting is saved to the last one you set before locking the car.
• The car audio system stopped working along with all warning chimes and turn signal indicators => wow no sound at all?
• The Vinfast app does not support the car.

• Remote control won’t work => apparently, they turn off remote control. I activated this remote control i guess before they turned this feature off.
• vehicle errors don’t show up when they happen on the car => does sound like your car and app are not linking with each other

Man, I’ve been having charging problems with 2 different level. 2 charges from Vinfast. It worked a couple of times but then it stops at 5% charge or 10% charge and now, lately a couple of times my car just doesn’t start, it comes up with all kinds of errors. I call the service center. Emergency roadside assistance and wait for them to organize that tow truck. And then after about 30 minutes it just starts again. It’s so frustrating. I’ve complained and now the service center has stopped responding to my complaints text messages. I have a open ticket. No one has called me back. I have all kinds of problems charging. So now I have to just go out and charge at Electrify America or EvGo, that’s my only option. I’m really frustrated with my Vinfast VF8. Are there lemon laws for EV’s???
