2012 Volt.... I open the hood and I noticed there's these little spots that have oil on them and I circled them in the picture the area that's next to the brake fluid scaring me a little bit cuz I don't know if brake fluid is leaking out of it and the other area is where I took the circles. Anybody ever have anything leaking out of these places

2017 with 68K miles. The CEL came on a couple weeks ago. I checked with the Voltage app and it had these codes. I cleared them, but today the CEL and codes came back. I'm in Maryland so the BECM should still be covered right?

Hey all, have been getting into doing more DIY repairs on my Volt and have been considering doing a transmission fluid change. Came across some great content on YT by a channel called Heartland Rebuilds, and saw that AC Delco 10-9395 Dexron VI trans fluid is what GM used from the factory. After doing some additional research, it appears that GM has a newer Dexron VI fluid that’s backwards compatible called 10-9243. My question is, should o just move forward with the factory 10-9395 or consider using the more modern 10-9243 formula?

I need advice because I feel like I'm running around in circles and am unsure what to do next.

Backstory: 2012 Volt, 122k miles, Los Angeles. It isn't passing SMOG so I cannot register the car. The check engine light keeps coming back with P1FFD and P1FFF (plus P1E00, and P0171 showed up once) along with the dash saying "Service High Voltage Battery System". The part that needs to be replaced is the coolant level sensor in the battery cooling system. GM has a bulletin about the solder joints failing inside this sensor.

What I've done so far:

Took it to the dealer. They reflashed the BECM and HPCM2 per the bulletin. Light came back 5 days later.

Took it back. They did a full diagnosis and their own tech wrote up that the surge tank assembly needs to be replaced. They said it wasn't covered by warrantee.

Opened a case with GM customer assistance. They talked to the dealer and referred me back to get it fixed. I did some research around this time about different warrantees and found out that California has a PZEV, which applies to cars less than 15 years old and less than 150,000 miles. My car satisfies that.

At the dealer, I had them run my VIN and confirm the car is PZEV certified. It is, which means the 15 year / 150k mile California emissions warranty applies, and I'm under both. They agree the sensor itself is a covered part.

Their denial: the sensor only comes as part of the surge tank assembly, the assembly includes non-covered parts, so the whole repair is customer pay. Quote is $1,800.

I got the denial in writing and escalated to the top manager at the dealership. No movement (I even asked him if it made sense, he said no). Filed a complaint with the Bureau of Automotive Repair today. Also sent a written escalation to Chevy customer assistance arguing the warranty follows the defective part and packaging doesn't void coverage.

Questions:

Has anyone had the dealer try not to complete their warrantee obligations? How did you get through this?

If you've dealt with BAR on a warranty complaint, how long did it take and did anything happen?

For the Volt owners: the standalone sensor is about $20 online. Has anyone replaced just the sensor at an independent shop?

Thanks
