Hey everyone, I have been an issue with my truck, a 2003 silverado ss. There are a few different things and I think some of them may be related.
1. Warning buzzer goes off and "service brakes soon" comes on the info center as well as illuminated ABS and (P) symbol. The warning lights will stay on until i shut the truck off
2. When the above is happening, the speedometer is erratic and the truck also shifts erratically, like its jumping between gears or it just revs high and shifting is delayed
3. Also, even when none of the above is happening and i engage the cruise control. The cruise will disengage or surge if I hit a bump
4. The left blinder doesn't work or also acts erratically, blinks super fast and then stops when you apply the brake. Yes, all the bulks have been verified on more than one occasion
I had taken it in once for this issue and they couldn't find anything definitive and didn't think the issues were related. Apparently they could nt find any fault codes either, which I found really odd.
