Have a 2011 HHR; after oil was changed now have alerts saying Service Traction and Service ESC. Car is running okay and has 65000 miles. We bought car 2nd hand so not sure about warrenty. what do these messages mean? sorry, I'm a car owner, not a mechanic.

 

Best thing to do is read your owners manual which has an explanation on the meanings of the errors. If you do not have an owners manual you can download them from the site here (use the search tool at the top of the page to find them).

Give your local dealer a call to inquire about the warranty - be prepared to give them your VIN as they will need that to determine the status.

What weight oil was installed? Did the warning go away?

 

In my experience, those two lights always mean big trouble coming. For me the first time was right before my original engine threw a rod, has to have the engine replaced. The second time was when I had messed up spark plug threads and the spark plug got blown out. The third time was when my camshaft intake actuator solenoid needed to be replaced. Pull codes if you have an obdc reader or just pay $65 to have the dealer check it out.

 

I started getting those randomly while sitting still with my foot on the brake. They seem to go away by either stopping the engine then restarting it or by moving on and applying the brake.

I get no codes. But I'm thinking maybe a camshaft actuator testing me.

 

I had these in my 2010 LS after I had some work done. The "Service Traction and Service ESC" warnings are usually directly connected to either a loose connecter at one of the wheel hub sensors, or perhaps even a bad hub.
Mine started out as sporadic.. would only occur on rare occasion, and would reset when turning off the vehicle. After that, it became more and more frequent. I checked the physical connector at each hub, but no luck. After my service tech rand the codes, it turned out that my front left sensor hub was sending the error code. replaced the hub and haven't had a problem since.

 

The OP cannot be to concerned regarding his problems. He hasn't been back since he posted his question.....almost 10 days.

 

Me, too. I had these popping up erratically, not very often but they would go away by turning off the key then re-starting. I bought a code reader and it was calling out the rear left sensor. I finally got the car up on a lift and found out that both rear hubs had already been changed, I could see where the wires had been spliced. I checked (all good with heat shrink) and taped up the splices then unplugged the bundle connector at the floorboard, cleaned it and plugged it back in. It may not have been connected right, I guess.
No more warnings, no codes. it's been a couple weeks, so far so good.
