Failure Date: 07/01/2020

While driving the vehicle it will loose driving power, check engine light will come on as well as epc light. When taken to a mechanic it was found out that the whole throtke body needed to be replaced. I was also told that this was a dealer only part, when the mechanic shop called to order the part from the dealership they were told that the part was on a national back order and that it could be 6 months to a year before a part was avaliable. When I called the dealership a week later the part was still on back order, and they said that they had over 200 on a list waiting for this part, and to keep calling back to ask about the status. I have not been able to drive my vehicle since July 2020, and as of today 10/22/2020, accordinf to the dealership there is still no estimated timeframe that this part eill be available. I fell that if there is that many that if they do in fact have over 200 waiting for the part then there must be somthing defective with the current part that is on the vehicle.

3 Check Engine Light On problem

Failure Date: 08/06/2016

Check engine light came on and a 200 mi. Countdown began indicating the car would not start again. We were over 500 miles from home on the weekend.

We could not turn the car off, nor stall it as the car indicated it would not start again. It was the nox sensor. I paid $625 plus tax to fix part of the fraudulent emissions system.

4 Check Engine Light On problem

Failure Date: 07/20/2016

The check engine light came on 7/14/16. I brought the car into the dealership on 7/15/16 and learned that the car¿s adblue heater had gone and will cost just over $1,000 to replace. The adblue heater heats the adblue to remove no2 for emissions, however Volkswagen is claiming that this is not covered under the emissions warranty. The adblue system has not other purpose than for emissions and should be covered under the federal warranty, as the emissions would fall outside of the federal regulations without this component. Proper emissions help to keep our entire population safe and healthy from the harmful pollutants generated by vehicles. Now the car will not start because of this false emission sensor reading.
