Corroded or loose ground wire in front of battery at the bottom.

Probably blew the driver's door speaker. Try listening if music is coming from the door speaker.

That's how I cured my leak, never leaked again since,

Could be a dirty MAF sensor but you will only get a code when it gets really out of spec.

Purge valve. GM#55573017

There may be a recalibration needed or you may have a faulty rear differential temperature sensor.

The manual states if you live in higher altitude to use higher grade gasoline if engine spark knocks..

They should have replaced the RCDLR module at the first sign of a problem.

 

[Traxy]

So how much did it cost you overall?

 

[Traxy]

Probably a dry blower fan motor bushing. Since they can't be greased you'll have to get the motor replaced.

Actually it sounds like a scrapping noise. At first I thought it was the brake pad screamer which made sense to me since there was 60k miles on a mostly city driven vehicle. So I changed the rotors and pads. But to my surprise there was still about 3/16" left on the pads before it hit the screamer. Then I thought wheel bearing....As it got worst it started to make a wobbly sound on top of the scrapping sound and that is when I realised it was about 3 times wheel rotation speed which pointed to the drive shaft. Put it up on a hoist and sure enough although not as loud the stethoscope pointed it out.

Well I found the source of my noise which I thought was a wheel bearing. Turns out it wasn't a wheel bearing but a bearing none the less. It's the steady bearing on the propeller ( drive ) shaft. So far I haven't found a replacement bearing and dealer wants to sell me the whole shaft. Going to bring it to A+ driveshaft next week to see if they can part source the steady bearing, if not I'll have to make a financial decision on a junkyard shaft or a new one. GM#42529901

If you have the same types of roads and potholes we have, no vehicle is immune. I think I will need to replace a front wheel bearing soon and I only have 99,000kms.

Or maybe it's just the crown in the road.

Water pumps fail on all vehicles. I had mine replaced a month ago with only 88000 kms (about 55000 miles ). I won't trade my Trax because it needs maintenance.

 

[Traxy]

Could be a lot of things like corroded coil contactors. These are good vehicles but they don't repair themselves, sometimes they need maintenance.

 

[Traxy]

Update: Drove the Trax all day and never smelled coolant once! I believe my problem is solved for now!

Tore through it this morning and saw that the seam between the water pump and thermostat housing was very wet and I could stick my finger nail in the gap. So thinking that maybe the screws had slacked or turned back I decided to re-torque them at 80 in-lb. The 2 top screws which were easy to get at with the torque ratchet took about half a turn before clicking and this closed the gap to nothing. The bottom screw I could not reach with the ratchet. Feeling around for it I realized I could turn it with my fingers, so I pulled it as tight as I could then pulled it tight guesstimating the torque with a small 8mm box wrench that happened to fit on the #10 Torx head. Now it's a waiting game...May still have to change the housing if it's warped.

Here's a picture of the water pump where the thermostat housing bolts to on the end.

 

[Traxy]

Turns out that's not where it was leaking from, coolant is running along the exhaust manifold and what doesn't evaporate from the heat drips from the flange at the CAT. So tomorrow I will inspect the thermostat housing.

I think I found my leak. Seems to be coming from the bottom of the oil cooler. Here is a kit sold on ebay for reference.

It is located at the bottom of the oil filter housing.

This picture might help situate you better. In my case it is a Hengst housing.
