While driving an alert comes on that states check engine system. As soon as this happens all power in the car turns off. Engine is still running but you no longer have any turning signals, brake lights, headlights, air conditioning, etc. It happens randomly and has almost cause me to be rear ended due to car behind me not knowing I was slowing down or stopping. This happens when I am not close to a dealership so they have not been able to witness this.

From a stop at an intersection, the initial depressing of the accelerator produced no throttle response and then suddenly the car lurched forward. This resulted in rear ending the care in front at the intersection. The collision avoidance did not stop the car before contacting the car in front. Even after the accident the car continued to respond in the same way until it was placed on the two truck.

I leased my 2019 Tiguan in March 2019. Shortly after (~1,500 miles), I experience my 1st acceleration failure. While attempting to turn left with oncoming traffic (with my 4 year old in the back seat), my car would not accelerate although my foot was pressing the gas pedal to the floor. After multiple seconds and multiple attempts to accelerate forward, I put the vehicle in park, turned it off, turned it back on, put in drive, and was able to complete the turn. Thankfully the vehicles coming towards me were paying attention and halted, or it would've resulted in a collision. This failure happened 3 more times shortly after, 1 of the them occurring when my husband was driving. While getting my vehicle in for service, 1 of the VW employees mentioned they receive calls regarding this same failure every week, sometimes every day. A 2nd VW employee mentioned they have never received a call on this failure for my vehicle. "??". the dealership performed a 26M1 software upgrade that 'should fix the problem.' Concerned for not only the safety of my family, but the safety of the drivers around me, I filed a claim with VW corporate and asked to be removed from my lease due to the failures almost resulting in multiple car accidents. They refused to allow me to get out of the lease as my experienced failures 'do not warrant the ability to be removed from the vehicle.' Shortly after the software upgrade, my check engine light came on and I've experienced the same failure 3 more times (1 of them while attempting to reverse). Here we are again' I have a service appointment scheduled for 09/10 and opened my VW corporate claim back up.

The automatic breaking sensors went off for no reason. Car started breaking on it's own. Luckily no car behind me. Car was in motion on a 35 mph part of route 30 in Indiana when it started to break suddenly. Took it to the dealership and they could not replicate it. I sent Volkswagen a message and they didn't reply.

The cars breaking assistance brings the car to a complete stop at any speed. It will break when nothing is around, when backing out of driveway, driving down freeway, and pulling out onto the road.

My brand new 2019 VW Tiguan fwd next day after buying showed multiple problems that related to transmission and breaking and a unknown source of rattling sound. I noticed when I cold start the Tiguan and let it idle for 3-4 minutes the normal engine sound slowly goes down but a louder and more noticeable rattling sound comes up. It is heard while driving also. It's concerning but what is more concerning is the that the Tiguan hesitates while shifting gears. I noticed it happens while accelerating from a stop. Not only it hesitates to accelerate you'd feel the cars struggle while shifting gears. Each time the gear is shifting you could feel the car is at a confused state and so you feel it thump. At other times I've experienced the car almost stalls where the RPM goes up but transmission slips. It doesn't change gear. The worst of all is that while slowly breaking the car tried to speed up. The RPM is also seen to go up. The very unfortunate news is that though the dealer's technician drove with me and saw the issue they don't have a fix. VW corporation also isn't providing a fix. There's other reports of similar problems. The Tiguan has a known transmission problem according to other owner reports. It may not be all Tiguan but my car is a lemon. The problem probably has to do with which location the car was manufactured. This is a very big safety concern. I am very worried about such erratic issues 2nd day. How did VW get past safety boards. They need to solve this issue before devastating events such as death or other things occur. No vehicles should slip gears while accelerating nor speed up while breaking.

The car stopped accelerating unexpectedly in the middle of the freeway while I was driving about 60mph. All kinds of emergency lights came up for no apparent reason, and the car blocked. The gear was locked and wouldn't respond to restarting the car. The car had to the towed, and after getting it in the truck I realized that one side of the headlights weren't working. The car has only 1700 miles. A similar but less severe event happeed threes days before. I took it to the dealer's service and they said they couldn't find anything wrong with the car.
