Why is my Volkswagen Passat losing acceleration after a few miles?

I have a 2015 Volkswagen Passat and after driving a few miles, it starts losing acceleration and I have to restart the engine to get it going again. Any idea what could be causing this issue?

It sounds like you may have a faulty throttle body. This is a common issue with Volkswagen Passats and can cause loss of acceleration after a few miles of driving. I recommend taking your car to a certified Volkswagen mechanic to have it checked and potentially replaced.

Have you changed your air filter recently? A dirty air filter can cause decreased acceleration and should be replaced regularly. Try changing the air filter and see if this improves the issue.

Another possible issue could be a clogged fuel filter. This can also cause loss of acceleration. I suggest having your fuel filter checked and replaced if necessary.
