I asked the driver and the guy said I am fine. Not sure what that means. I only had my wife with me, and didn't need an SUV.
I requested an UberX but an SUV showed up. Will be charged for an UberXL?
The Guru Take
No, you will be charged the UberX
Don't worry! You will be charged for the service you requested, in this case, an UberX.
Uber enables SUV drivers to accept both UberX and UberXL requests, so even if you request a regular sedan, you may end up with SUV. This happens often, but this upgrade is free."
(There is a common trend, where the riders try to take advantage of this by always requesting UberX even if there are more than 4 people in their group. They do this in hopes an SUV shows up and they save a few bucks. However, this can be reported to Uber and the fare can be adjusted retroactively to match the rate for UberXL.)
