2015 legacy valve body problem?

[waltersc88]

In November 2024 I had to change out my battery and every since then my car has been going crazy. Might be a coincidence, I don't know. For 2 days after my car wouldn't idle unless I gave in a little gas then after 2 days that issue stopped and hasn't happened since. Then about 2 weeks after that I started my car in the morning and all was good, put it into gear and a bunch of lights came on and they now come on every time I start my car. AT oil temp light, BRAKE, ABS, and my traction control icon. Then my info screen will display Transmission, Electronic Parking Brake and Vehicle Control System. They stay on at all times when driving. My car starts and drives perfectly fine, no loud noises, doesn't shift weird or hard. Have no clue what it is. I've had my battery, starter and alternator checked and they are fine. I've disconnected battery and reset my ECU. My buddy seems to think it's the valve body. Any information would be much appreciated

You've probably have already done this: My quick and cursory Google search states (in part) that blue smoke, excessive oil consumption are just the some of the symptoms of a failing valve body. No mention of ABS, brakes or traction contol warning lights. There are a number scenarios, examples and explainations.

What's the service history?

Other than regular oil changes I've not had anything else serviced

10 years old and no service??? It could be anything! Rat eating wiring. Clogged or damaged sensor, harness...something grounding out. If it started with a battery...I'd start with that and that area.

Get the codes checked. With all the dash lights coming on, there must be at least one code set telling you the issue. Don't let a mechanic, sorry, a 'technician' start throwing parts at your car until you find out the cause(s).
