My wife recently had her 14' Acadia SLE serviced at the dealership for a wheel speed sensor issue, and they replaced the entire wheel bearing. After the service less the first drive after we serviced the vehicle she got a cel. I had it scanned and the fuel pump is now going bad. Is it possible that a vacuum seal or something else was broken during the repair?

Possible but not sure how that would relate to fuel pump trouble codes.

What trouble codes are showing?

Seems unlikely without knowing what was done 'under the hood' beforehand to diagnose the problem. Stranger things have happened, though.

You will probably lose any argument with the service center if you try to put blame on them for this new problem.

Clearing the code, checking out sensor connectors, and finding out how long it takes to set the CEL again would be the very first thing. There's a chance illumination of the CEL may not occur. Two of my vehicles displayed a CEL after service work. I found the MAF sensor connector(s) had been bumped at some point. I did the first two steps and the CEL never returned. Once, I didn't even get the vehicle scanned - the problem was that obvious.
