I was driving along today in the left lane of a 6 lane busy highway with traffic moving along at about 80 mph when out of the blue with no warning whatsoever, the Taos engine shuts off and just lost all capability to accelerate. I had to then maneuver across 5 lanes of 80 mph traffic as I was rapidly losing speed to make it to the shoulder. All this to say, this put me in a very dangerous situation with no forewarning that anything could be wrong.

I only found this forum because I found a post here on the exact same topic when I googled it. Also saw multiple people in that thread with the SAME ISSUE. I loved this car, but now do not feel safe whatsoever driving it. Especially not with my 2 year old in the back. What are my courses of action to get out of this death trap?

Thanks and hello!

Edit: it's an S model

Was this the AWD? From what I’ve seen, others have been able to take it to the dealership and make them buy it back.
No, it's an S model. Therein lies the problem. Doesn't seem like VW is acknowledging that it happens to S models. We will definitely be reaching out to them just haven't had a chance yet as this just happened last night. Wanted to come here in the meantime. Thanks for input.

Thanks. I was asking because the S comes in AWD (4Motion) and FWD (Front Wheel Drive) and most people posting in the forum with this same issue had AWDs. If your S is a FWD, they’re going to have to acknowledge that these issues persist in both options across trims. Scary stuff. Hope you get it resolved.

S is only available in FWD. I guess I should have clarified. And yes, scary indeed. Thanks!

First post here, just registered. We have a 2023 SE FWD reserved, expect it next month.

A question about your incident where the engine shut off: Were there any indications or messages you could see on the dash when this happened? Probably not otherwise you would have mentioned them.

I wonder if this was a malfunction of the engine start/stop function. Did you have that enabled or disabled?

This is a very serious issue. Unless it can be determined that this failure was related to just your car, we have to assume it can happen to all of them. Nobody will feel safe driving their Taos unless the cause is found and fixed. In fact, I am considering cancelling my reservation and getting the $500 deposit back if VW can't say they have fixed it.

There was no warning indicator whatsoever.

It apparently is a known issue with AWD models only. Except mine is an S model. Not good for VW. Not good.

And it happened again this time in town when I had just took off from a standstill. Thankfully there was a drive to pull into and I lucked out in that regard once again.

I would strongly suggest you cancel that preorder. The really sad thing is i absolutely LOVED that car otherwise. Damn shame.

We will be on the phone with VW corporate 1st thing Monday morning.

And I did have auto start
/stop enabled both times. It took me three tries to start it back up this time. Stay clear of this vehicle, people.
Thanks for the additional information, and I am glad you're going to be on the phone with VW corporate Monday morning. Please keep us posted here with how that call went and what VW's plan is going forward.

I haven't completely researched the history of the problem with the AWD models and how far along they are in the troubleshooting process, but I recall there was a stop sell order on the AWD's earlier. I'll have to check and see if that was for the engine stalling / stopping problem.

We still don't know if this is a design or manufacturing or software defect that is present in all cars / models, or if just your car is having the problem. Like I said earlier, it is best to assume all cars are affected until proven otherwise. I had an 87 Honda Accord many years ago that had a problem where the engine would stop when I stopped the car, like at a red light. That turned out to be a cracked insulator under the carburetor due to age / wear & tear. Didn't affect all cars, just mine, but eventually other cars would likely develop the same problem when they got old enough.

Since we now know you had the start/stop system active, that alone doesn't prove it was a malfunction of the system, but it leaves the possibility still open. If you had turned it off, we might be able to say the system wasn't the cause (or at least it was less likely to be the cause). In fact if you are going to continue driving the car, for the time being I would turn the stop start system off every time you drive it and see what happens over the next week. I would also understand if you just want to park the car until the problem is resolved.

I like the stop/start system in that it helps get better mileage, and on our test drive it seemed to work very smoothly (my wife was unaware the engine was stopping/starting while she was driving). It is good you can disable it if you don't want it (like you are stopped for a very long slow moving train and you want to keep the A/C going). But it would also be good to have it disabled by default so you don't have to turn it off every time you start the car, if that is what you want. Especially if there is a suspected problem like you are having. Imagine you forget to turn it off one time and that's the time your engine dies on the freeway.

I'm not going to cancel my reservation at this point, the car isn't due until sometime next month and the deposit is refundable if we decide to cancel, so no risk of just keeping our place in line. Like you, I think it is a great car and I wouldn't give up on it until you see what VW is going to do about it.

My previous car was a Chevy Volt (drove it for almost 9 years) and I felt the same about it, it was the best car I ever had, or ever will have I'm pretty sure. Right up until the day the main battery died, 10 months out of the 8 year warranty and they wanted $18,000 (plus labor) for a replacement with only a 3 year guarantee.

I was going to give them the benefit of the doubt at first that perhaps this was just a one of thing with my vehicle until I did a bit of digging and realized there are many more people online who have reported this issue. How many more who haven't went to an online forum about it?

I'll keep this thread updated with developments.

You should also file a problem report with NHSTA if you haven't already:

Report a Safety Problem | NHTSA

You can see all 5 recalls issued for 2022, as well as read the 51 individual complaints here:

Did some more reading on NHTSA website, found that one of the recalls was the reason for the "stop sell" order issued to dealers for the 2022 AWD models dated August 03, 2021. It WAS the same problem of the engine shutting off unexpectedly, but it is described as shutting off "when coming to a stop".

In both your cases, you were NOT coming to stop (and you have FWD, not AWD).

The recall was to update the ECU software. You may have not had this done if your car was a FWD, because they might not have sent you a recall letter. I'm not sure if this software update would help your FWD, but it might.

Before I retired 6 years ago, I had 36 years of aerospace engineering experience which included troubleshooting problems on complex airplane / spacecraft systems. I've had lots of experience troubleshooting and fixing software problems and one thing I learned is while you can test that software correctly does each thing that it is required to do (they have requirements documents the software engineers follow in writing the software and the testers use in testing), you can NEVER test completely that the software DOESN'T do anything/everything it is NOT supposed to do. Thus problems like the ECU software one are found in the field, investigated and then fixed.

I will say that after looking at the documentation, that VW gets on top of these issues pretty quickly once they are identified. They took 1 month to investigate the problem (reasonable amount of time), and when they presented their findings at a safety meeting, they decided to issue the recall the next day.

Well that's good to hear that they've previously been responsive. I have a 2 yo and don't feel safe whatsoever in this vehicle right now so if they give us the run around, it could get ugly. Hoping not. Trying to hold off on judgement on VW until speaking with them. Thanks for the info!

If you don't feel safe (especially when the 2 yo is in the car), the most conservative thing to do is not drive the car, but at least you can disable the stop/start if you do. If it's something like the ECU software problem, disabling start/stop may NOT prevent the problem though.

I really don't think you will get the runaround, especially if you are talking with VW corporate. Try to maintain a calm professional attitude but stress the importance of the issue and let them you know you don't feel safe (would not hurt to remind them you are transporting your 2 yo in the car). They have a well defined process to follow in these cases, which they will expect you to follow. I would try to have the attitude that this is very serious and you want to work with them to be sure you are doing everything you are supposed to do to move the process along.

They should open, or already have opened, an investigation. Even if it is just your one car having the problem. Your case may be the one that kicks off the investigation. Tell them you want to be kept in the loop, see if you can get an investigation number or some way to track the progress on the issue. Maybe get a name / number / email address of someone where you can get updates.

I once had a problem with laptop computers made by NEC. After working my way up to the VP of customer service for USA, I still was getting nowhere. I looked up the name of the NEC worldwide CEO, did not list his address but I found where the worldwide headquarters was located in Japan. I sent a letter to that address with the CEO's name at the top. While I never got a direct reply, about a month later the USA VP contacted me and he had a COMPLETELY different attitude. I was now the most important customer on Earth to him. His response involved an offer of a personal factory tour, led by himself, and sending two NEC engineers to my office to do the repair and then taking me to lunch at any restaurant of my choice (NEC paying the bill of course). Had a really interesting discussion with the two NEC engineers after they found I was also an engineer. They said I was famous at their factory because the worldwide CEO had sent every employee at that factory a copy of my letter!

Good luck! I've had no luck with the dealership or VW Customer Cares... (well, they really don't care). I have had mine stall but thankfully I was on a city street at 5:00 am. Numerous other issues, with NO resolve from the dealer or VW Corp. I can't afford to trade it in (I'm too far upside down). Needless to say I'm stuck with severe anxiety every time I drive (daily) wondering if I'll make it safely to my destination.

I'm thinking this problem with the engine stalling will turn out to be something with the ECU software and they will issue an update to fix it. Either that or it's the start / stop system acting up. I am pretty sure VW already has an investigation going and will likely issue a recall as soon as they figure it out, to make sure every car with the problem gets fixed. I do think they should keep owners better informed on the progress of the investigation somehow, but until they find the cause it is hard to estimate how long it will take.

The AWD already had a recall for engine stalling but it seems like the FWD cars are also reporting the same or very similar problem.

I haven't taken delivery of my 2023 SE FWD yet, still 'in transit'. It says it was manufactured in August and it can't take that long to get from Mexico to Texas, so it may have left the factory but is probably sitting in a storage lot next to the factory.

I was driving along today in the left lane of a 6 lane busy highway with traffic moving along at about 80 mph when out of the blue with no warning whatsoever, the Taos engine shuts off and just lost all capability to accelerate. I had to then maneuver across 5 lanes of 80 mph traffic as I was rapidly losing speed to make it to the shoulder. All this to say, this put me in a very dangerous situation with no forewarning that anything could be wrong.

Contact a local attorney who is a person who deals with lemon law cases. Do not drive the vehicle ever again. Tell them you are terrified to drive the vehicle. Have it towed to the dealership do not drive it have it towed contact. If you drive it to the dealership it will indicate to them that you are not afraid to drive this vehicle. We do not know why it shut off. All we know is it did. Contact Volkswagen customer relations and tell them what you are doing.. Hopefully the lawyer will take it from there.
