I recently bought a 2011 Chevy cruze and stayed having issues. It starated with the passenger window going down on its own. At first it would go right back up and now is delayed for several minutes before it will go up. Then the radio started flashing on and off randomly and the abs and maintenance traction control lights keeps appearing. Then the last few week the cat has been slow at cranking this morning it wouldn't crank at all the first two attempts them it started up. My battery voltage reads 15.4 always id that matters.

When it comes to electrical issues, I always ask if you've had the TSB regarding the negative battery cable performed? Considering our Cruzen are essentially computers on wheels, that cable has caused members some crazy issues.

Not a car anymore, a computer, depends on a sharp power on reset voltage to reset all the computers to zero. Try replacing your ignition relay under the cover of your engine fuse relay box, Back of it tells where the ignition relay is located at. Without a good POR, those computers will go crazy.

Measuring 15.4V on the battery terminals? Sound a bit high unless you are in subzero weather. What does your DIC say? Measured a good voltage across my battery terminals, DIC was sure low. Problem was in the battery terminals themselves, stuck in a piece of bare copper wire that turned brown, even with some green on it, copper oxide, an excellent insulator.

Drilled opposite holes in mine where that crimp is in the terminal, pulled out those corroded wires, cleaned than and soldered those in. Or can just buy new cables. Putting all those positive terminals on that plate was not a good idea either, way too close to acid fumes from the battery. Just wire brushed those clean and coated with silicone grease to help retard corrosion.

What is a tsb? I know nothing about cars lol. I haven't don't anything I just bought it about a month ago and all these issues have started. I have 3 small kids so I'm worried about having them in it not knowing what the issues going on are.

I live in ky so it's not very cold. We've actually had days in the 70s since I got the car and the battery voltage was still 15.4.

I would suggest starting with the service bulletin for the battery cable. Tell your dealer that you have been having weird electrical issues and ask them to look up 'special coverage 14311'

See thread:
http://www.cruzetalk.com/forum/25-g...al-coverage-14311-negative-battery-cable.html

After that, you can have the battery tested, typically for free, at any auto parts store. The stock AC Delco batteries do not have a great life expectancy and as mentioned, voltage fluctuations as in a dead cell or low battery voltage can cause all sorts of weird electrical issues.

There isn't any messages on the dash when I go into the settings they just pop up from time to time. They say maintenance traction control and maintenance stability track them and abs light started flashing

Ashley,

First, welcome to CruzeTalk. Now on to your questions.

The TSB (Technical Service Bulletin) we're referring to is http://www.cruzetalk.com/forum/25-g...al-coverage-14311-negative-battery-cable.html. As long as you're under 120,000 miles it's a free repair.

The electrical charging system in the Cruze is variable. Normal voltages will read from 11.6 to 15.4. If you're seeing the voltage stay on the high end for long periods of time chances are your battery is near the end of it's life. However, before replacing the battery get your negative battery cable replaced. Don't be surprised on a 2011 that you need to do both. The battery is a routine maintenance item and if it's the original battery is well over five years old at this time so it's had a good long life. Also, slow cranking is another sign of a battery getting ready to strand you someplace.

DIC is shorthand for Driver's Information Center, which is the small rectangular screen between the speedometer and tachometer.

This is high, it's a 12 volt battery that will read I'd say up to 13.5 while running and being charged by your alternator and under load(while you have electrical demands running and really cranking on this battery) in my experience (I've never had this in my 2011 Cruze ltz) you could have a short in some elctrical wiring meaning there is a touching of two or more wires messing up communication from the computer or electrical charging.

What is a tsb? I know nothing about cars lol. I haven't don't anything I just bought it about a month ago and all these issues have started. I have 3 small kids so I'm worried about having them in it not knowing what the issues going on are.
A TSB is a technical service bulletin, General Motors release not a recall but an open bulletin to Cruze owners about their negative battery terminal, the crimp at the end can be faulty and build resistance giving the computer a real hard time receiving appropriate electrical demand, and at 6 years old those problems would only get worse and pretty wild at this age, being a low cost fix (a trip to the dealer) its worth the shot


What is DIC and how do I measure it?
Drivers information center, that in the Cruze is the small screen between the rev-meter and speedometer, and nick is referring to measuring the battery voltage with an electrical meter (volt-meter)

I've seen 15.x before when I had a super dead battery and the car was trying to charge it like crazy. Anywhere between 12.x - 14.9 is usually typical of the Cruze with the motor running.

Again, this is sounding more and more like a bad battery/bad cable, or combination of both.
