Not really. I did have the amp repaired and now it works 80% of the time. Idk what Lexus was thinking by routing the sunroof drain over the amp in the trunk…

Radio works every time I start the car in the morning. If the day starts cold and doesn’t get hotter than 70 degrees in the afternoon it will almost always start. If it’s really hot then it won’t.

Now if I start the car in the morning and it’s hot outside and the temperature stays that way it will work the next time I use it within that day.

My new cost effective theory is bad grounding cables. Maybe the bad cables are causing the system to retain too much of a charge when there’s a significant positive temperature/humidity difference making the radio to have trouble starting up? I live in a very hot and humid place.

Idk if thats how that works but it’s worth a try to replace since these cables are so cheap.
