Hello and welcome. code P069E is a code for a fuel pump control module fault. the aftermarket equipment wont void your warranty, however if the problem directly relates to the aftermarket equipment, then the repairs wont be covered by the factory warranty. botXXXXX XXXXXne. GM will only cover repairs that are GM equipment only. at this point, i don't see the radio being a issue. but I have seen a few aftermarket remote starts cause some issues.
If there is anything you don't understand, or you have more questions, Please feel free to ask me!
There was also another code that they said came up it was P2534 do you know what that is caused by
This code is a voltage code for the transmission, this code is almost always set by a aftermarket remote start set up.
DTC P2534: Ignition 1 Switch Circuit Low Voltage Circuit/System Description
The transmission control module (TCM) samples the system voltage on the Ignition 1 voltage circuit every 0.1 seconds. Lower than normal voltage may be inadequate to operate the transmission control solenoids properly. Improper solenoid operation may cause erratic transmission operation, which may result in internal damage.
