2010 Volvo XC70 fuel gauge issue

Back to the problem at hand, has anyone raised the vehicle and smacked the gas tank with massive rubber mallet to see if it frees up the float?

Good point. But actually since I discovered the fuel gauge is inaccurate I have been monitoring the odometer for refills and tracking how many gallons I install with each refill. Highway driving has given me ~ 18mpg, whereas city traffic driving has given me a very concerning 7~9mpg. Iā€™m not sure if this was the case prior to the tank running dry because I wasnā€™t monitoring the gas efficiency like a hawk as Iā€™m doing now because of the fuel gauge issue. So if a damaged fuel pump isnā€™t the reason for this incredibly poor fuel efficiency (should be 17 city/ 20 highway) it leads me to believe there are additional issues with the fuel system furthering my hesitation to keep this car. Thoughts? And thank you for the feedback!

If those MPG figures are based on EPA estimates they are estimates based on ideal conditions. If your city driving involves a lot of stop and go with frequent period of idling with AC on, that might have been the same MPG when new. Rarely are EPA MPGs achieved, occasionally they are, sometimes even surpassed.

Why are you doing that ? Didnā€™t the dealer offer to fix it or take the vehicle back ? That is the only 2 options I would consider . People donā€™t pay good money just to have a work around problem right away.

Doing it for the time being until I can get the car back to the dealer for repair or return.

How much time is this dealer going to give you . Many places have a 7 day return policy . Plus if you accumulate too many miles there may be a mileage charge . Stop wasting time and make a decision .
