Power loss, car runs fine then volts drop
2008 Cadillac CTS 3.6 V6 280000 miles
I’ve checked everything I can think of, battery, alternator, I changed out the inline fuse on the alternator power cord, replaced the battery current sensor. I can’t seem to figure out what the problem is. It runs fine when you first start it, then it’ll drop from 14.9 to 11.7 and slowly drop from that to 10.6 then drastically drop. Weird thing is once you first start it it’ll like ramp up or something then the volts jump up then back down. I can’t figure out the issue. Any help would be appreciated.

Mine is doing something similar it's runs good and I've replaced the battery altinator pretty much everything except the fusebox. My service battery system comes on every once and a while and sometimes I hear a dial up tone kinda in my dash around 40 moh and the car shudders

Mine too ugh... What to do now ?? With the check battery charging system situation idk
You've got a short somewhere in the car that's why when you first start it you got good voltage and then it slowly goes down and goes down something on the car shorting out to the ground either. You got a skin wire that's slowly grounding out and killing the battery. Or you got something like your blower motor or your headlights or something that are that are dragging your battery down after you start the car and turn it on or it gauges something is either grounded out or shorted and slowly draining the battery or something like your blower motor or your AC compressor or something is bad and it's pulling too much juice and slowly dragging the battery down. And also check your alternator with a volt meter to ground and make sure it's putting out. It should be put down somewhere around 14.5 volts. That's what mine puts out and it stays that way when it started the whole time to the battery and the whole charging system and it shouldn't drop from that even with your AC and everything on it should still be above 14. But I'll say you got a short somewhere or a wire somewhere skin that's grounding out and solely killing your battery or some something on your system is slowly draining it. After you start it are your alternator. Could be working at first and then stop working when you get going on. The car gets up to speed over a dial. Is it a used alternator? You said it was new are you? Did you buy it at AutoZone? Because they also have cheap alternators and I bought multiple alternators that were bad straight straight out of the box brand new that weren't charging

Ya cambie sensores de impacto y revise los conectores y la luz sigue encendida todo parece bien ... pero esa luz es muy estresante verla encendida

Здравствуйте, возможно проблема в передних сидениях. Нужно снимать и проверять их. Часто бывает что может порваться мат присутствия пассажира или водителя. Или проблема в фишке подушки безопасности под сидением
