We got our Atlas 12 months ago in December 2018. The check engine light came on a few weeks ago, so we took the car in. The dealer claims that we got a batch of bad gas that ruined the fuel injectors which they now recommend replacing for $2500. The bad gas claim voids the warranty so we are on the hook to pay for repair. Interestingly, we get our gas at the Shell station right across the street from the dealer where they fill their own cars. We initiated an investigation with Shell corporate. Their assessment shows that the gas was fine, and they haven't had any other complaints about the gas so they deny that the gas was bad. We escalated the issue with VW to a regional customer service agent who stands behind the dealer's claim that we used bad gas which voids the warranty. I'm very skeptical of the bad gas claim, since the dealer doesn't offer any evidence to support the claim and Shell denies it. Seems like an obvious ploy by VW to get us to pay for an expensive repair on a 1 year old vehicle. Any suggestions on what to do from here? I'm inclined to take the car to an independent shop, do the least expensive thing to get the check engine light off, sell the Atlas and never do business with VW again.
