Finally got her back

[TheBoyNextDoor]

I finally got my H2 back after being left at the stealership for over a week, the problems that I had were as follows:

Climate control wasn't functioning properly

Side mirrors would not work

Speedo not working

parking lights not working

The service manager said that a bunch of codes came up on the obd scan and the culprit was the Viper 7900 alarm systems that had installed a few weeks ago at a local shop, apparently the remote start system somehow interferred with the ecu and cause the vehicle to go haywire.

Is this true or are they just trying to blow smoke up my azz by trying to blame it on something that's aftermarket ?
