Are there any warning lights on?
It is not likely that they did anything wrong while doing the tire rotation. The maintenance light is totally different from the warning lights that indicate a problem with the ABS or vehicle skid control system. If anything got damage as far as the wiring to the wheel speed sensors which detect wheel speed the vehicle then translates that through the vehicle skid control computer or ABS computer then to the combination meter/speedometer and on to the computer there would be a code set in the system. The ABS and vehicle skid control lights would be illuminated. My recommendation would be to do a hard reset by that I mean remove both battery cables from the 12 V battery which is located in the right rear quarter panel of the trunk apply jumper wire across the two cable ends while it's isolated from the battery for about 10 minutes then reinstall the cables drive the vehicle and see if the system reset.
OK let me know how it goes. Just make sure that you place a rag or something over the top the battery so the cables and jumper wire do not contact the battery.
