I have a 2007 tahoe that developed multiple warnings. service parking assist, hood open, remotes don't work, now traction control and stabilizer off, abs light flashes. I took it to jet chevrolet and they diagnosed 2300 worth of repairs which I have a hard time believing. I thought it was the bcm. Any assistance would be greatly appreciated.Its been a great truck.

 

before you do anything, clean the electrical contacts from the battery and the, especially any grounds. My 2010 suburban was going haywire and went to the dealer several times. they never found or fixed the issue. I ended up finding a video on youtube with someone who had similar problems. he fixed it by cleaning the battery contacts. I tried it too and it worked. zero problems since then. good luck.

Just recently replaced the negative ground cable in my 2007 for all kinds of electrical anomalies, lights dimming, random no start like a dead battery.
