So recently my C7 Corvette has had issues with the left and right signal acting as if the battery in them is going out/dead ( excessive voltage dash warning ). Additionally, the trunk latch has automatically opened. Also, the rear view camera turning on when in park/drive.

I had Morimotto smoked taillights put in 3 months ago and rode around with them in for 2.5 months with no issues. Then my battery starts draining to the point of dying even though I use it as a daily and the battery has a date of being fresh since August 2021.

The first dealership says that there is a parasitic draw coming from the aftermarket tails ( 200-300MA ). But what I do not understand is if I switch out for stock ( rebuy the stocks I sold ). Will this actually fix the issue if it is a BCM module issue? I already put in a different set of Morimotto's and had the same result of things happening. I've used dielectric grease, made sure all connections were tight etc. Even the third brake light is showing as if its activated.

I am hoping to hear back from someone in the community who has recently had some similar issue to this because I am stuck in a bind of going back to the dealership for another diagnostic to replace a part under the GMEE warranty or to put in stocks and potentially waste money that wont fix it.

 

Do a search using the term "morimoto" and you will have your answer. This is not a BCM issue.
