This is my first post and I was hoping it would be a better topic then help! My wife has a 2016 T8, love the truck, but lately I have been having a serious issue with a reduced power turtle light and loud bang coming from the back under certain conditions. So background: 58k miles regularly maintained, when the car has about 1/4 tank of fuel left and 1/4 or less charge intermittently there is a reduction in power, sometimes a loud bang sound coming from the rear of the truck (electric motor I assume) and the most frustrating part doesn't always throw a check engine light. I don't know if anyone has experienced this but trying to explain it to a Volvo tech without codes is challenging to say the least. Any help is much appreciated!

P.S. - wife just called and said it happened again on a full tank of fuel and charge and still no code?????

 

Are you just checking for CEL's? or do you have a scanner than can communicate with all the modules in the car? If it can only read CEL's and there is no light on the dash, you might need to get it checked with a better scanner to see if there is anything stored in the modules.

Loud bangs usually aren't good, I personally would limit driving until it is checked out further.

 

Yeah just a code scanner, after driving it more it appears it only happens upon braking, almost like the ABS module/tone ring/speed sensor is faulty. I've also read that there could be an issue with the emergency braking with 2016's. In any case I'm trying to find a specialist because the dealers around me leave a lot to be desired.....
