service traction /ABS light comes on upon starting car sometimes comes on after driving awhile. What is causing this problem

 

Loose wires, bad hub, VVT solenoids dead, timing chain stretched.
I could guess but , I will ask questions.
Is the check engine light on?
if it is, what codes are present?
any brake work done recently?
hoe old is the battery?

 

Is this an HHR ?
If so, what year and model ?

 

It’s listed as a 2007 HH

 

Welcome..

 

I had all these lights come on with my 2010 HHR. I got rid of it a few months ago but had purchased a 2014 Chevy Malibu with low mileage in August through a private party sale. The car had a "Service StabliTrak" warning that came up on the dash. The seller was waiting on a wheel bearing hub to come in and change it before I took possession on the vehicle.

After digging around and finding a YouTube video, I found out what the issue was with my HHR and that this guy saved me ~$500 - $1K in service costs!! I would probably have done it myself or with my dad but God bless this guy that he wasn't going to sell it to me without fixing it!!

Anyways, here is a link to the YouTube video and how to fix the wheel bearing hub.
At mark ~1:00 he talks about needing to visit the dealer or an ASE certified mechanic that has the equipment to diagnose the powertrain system. This will let you know what wheel bearing to replace.
At mark ~2:35 he states that the reluctor (sp?) ring on the wheel bearing is most likely the culprit.

Good Luck!!

 

Sometimes even an ASE certified mechanic is right, but probably not this time. Most likely VVT valves.

 

I always change wheel bearing hubs in pairs front usually! A code reader will tell you the code and the internet will tell you what the code means, it could be several things
