There was a PUMA issued a while ago in Germany for a batch of faulty ID7 HK Booster DSP/Amp units, but this really only affected bass, as it only drives the underseat woofers.
If the OP’s car is ID7, the mids and tweeters are driven by the RAM (receiver audio module), which handles all sound, so distortion should be evident across radio, telephone etc played loud.
Maybe worth double checking the harness connections to the unit in the trunk just to rule it out.
At the OP is the distortion present on all types of audio sources played loud ? Also what are your audio/eq settings as you mention “certain songs” which may relate to certain frequencies.
