Okay, I'm having a very strange combination of warning lights come on on my 2010 HHR. I first noticed a problem when I was slowly pulling to a stop at a crosswalk. My Anti-lock brakes came on even though I wasn't breaking hard and it wasn't slippery. When I pulled into a parking spot my ABS and traction lights were on and it was showing "Service ABS", "Service Traction", "Service ESC" I believe. Looking these up shows a probable Wheel Speed sensor problem. To complicate or confuse matters thought strangely my Airbag light also came on a while later. Over the next few days the Traction/ESC/ABS lights and the airbag lights have randomly been coming on and off. Sometimes just one or the other set, sometimes both, and like twice all the lights went off. Last night just the airbag light was on when I went to work, and before I left I tried wiggling the wires under the drivers seat out of desperation and it seemed to make the airbag light go off, but then as I started driving home the Traction/ESC/.ABS came on again.

I'm probably going to take it to a shop I'm just wondering if there's something that might tie these together. I'm just hoping it's not too expensive. It's either they're related somehow or it's just my bad luck to have two separate problems happen at almost the same time. Thinking about it it could just be two separate things as I think my airbag light did come on once several months back and then turned off again.

 

Low battery... Have the battery and charging system checked. Most parts stores will do this for free.

 

Yep, battery. It could also potentially be the underhood fuse block is loose. Getting that free load test and charging system test that greybeard mentioned is a much easier test. That's your first step.

 

Thank you, I'll go get it checked. I did have problems with the battery a few months ago where it got so low it wouldn't start, but I charged it up and it seemed fine, but being so low might have damaged the battery, so I'll get it checked, also I haven't replaced the battery since I got the car a few years back, so I'm not sure how old it is. I just have to decide where to go. The battery isn't exactly easy to get to, can they test it from the connections under the hood while it's in the car, or do I have to pull everything out of the trunk to pull it out? Not too bad if I do, but just a bit tedious compared to most cars. I'd have to do so anywy if it is bad to replace it anyway. I kind of hope that is the problem because it's relatively quick and easy.

 

No, have them test it at the battery!
removing a few panels and carpet isn’t as bad as waiting for a tow truck.

 

Well, went and got it tested, all the lights were off on the drive over, and the guy said the battery was a bit weak, but it could just be a low charge. But said the alternator is putting out plenty of charge to recharge it normally. So I brought it home and put the charger on it. I set it to 2 amps and am going to leave it on for maybe a day if I can(guy recommended either preferably 2 amp for 24 hours or the 10 amp for I think 10-12 hours, but said that lower amps are generally better.). It was at about 75% according to the gauge on the charger. This is the second time it's run a bit low. The problem I think is that right now with the current world situation I mainly only drive like 2 blocks back and forth to work and I don't think it's a long enough drive to recharge the battery from starting it up. Plus I have the AC going, not sure how much impact that has other than the fans maybe.
