So I bought a 2006 Equinox with 10k miles. Since day 1 I've had cold start issues repeatedly with no result from dealership, a thumping noise in the rear (EVAP vent solenoid issues) still remains unresolved, and dozens of other mechanical issues to include; speed sensors failure/replace hub assemblies, 3 window motors, body control module reprogramming, re-calibrate electric steering, rear windshield wiper motor, temperature sensor, TWO alternators, failed throttle body, reprogrammed PCM and secured inlet pipe, transmission replaced and the rear suspension will not stay aligned, therefore wearing my tires out and significantly lowering my mpg's. My heat stopped working twice, and the solution was adding coolant. And on more than one occasion, my A/C has stopped cooling or cools intermittently and on two occasions when I turned it on my A/C it spits ice chips and white 'fog' at me.

However, this week was the final straw for me. I've had a water noise coming from my dash, an odd smell when using the air, A/C and heat (even after changing filters), for over TWO years. They keep topping my coolant off tell me it's a known issue with no resolve, just like the thumping noise.

This past Sunday however, it over heated for the first time, stalled and spilled coolant in my driveway. I take it in and I'm told it's a sticking thermostat, which they replace $360 and tell me it will correct the water noise. When it doesn't they investigate further to find that there is air getting into the Heater Core and possibly leaking coolant into my Cylinder Head & Gaskets, which over time caused the thermostat to stick. So all this time I've been complaining of water noises in my dash the GM Bulletin's were pointing mechanics in the wrong direction and now I'm on the hook for a $1600 repair if it's only warped the Gaskets, but $3500 if it's also damaged the Head. Which is somehow related to the cold start and misfire issues?!?!

Here's what I don't understand though; how can these issues be happening with so many people, hundreds/thousands of complaints across the Internets, yet consumers have absolutely no recourse against GM? I've spent hundreds of hours (time = money) and thousands of dollars since 2006 with these issues, all the while paying top dollar for a vehicle which has lost value faster than any other I've owned. Ridiculous!

I have that same problem and I've been wondering what in the world is going on. Looks like I'm going to be getting rid of this car as soon as possible!

My 2008 Equinox is being repaired today. Heater core replacement etc. I've had the water sloshing sound for over two years, the dealer "bleed" the system twice which never fixed the problem. Now I have coolant leaking all over the floor near both floor vents. The repair will be over $1,000 on a vehicle with 69k miles and I have still have 7 more payments left. Unreal.

Ya know, the "funny" thing is that when you talk to GM about it, they act like they are unaware of any Heater Core issues and they make you feel like it's just YOUR vehicle. However, I've visited dozens of forums researching this problem and by the number of people with the same issue, it's clearly a manufacturing defect. How do they get away with this stuff?!?!

Make sure they check your Head Gaskets and Cylinder Head. All that coolant has been leaking somewhere all these years and most likely causing major damage elsewhere, like mine.

Thanks for the information. A good portion of the coolant actually blew out of the vents on to the inside windshield and on the floor (both driver and passenger side). I opened a case with GM (like they really care). The grand total is $1,093.63 which included a $200 discount and a 12 month, 12k mile warranty. Discount for what? Who knows. I'm so irritated I could drive the car right through the showroom window.

I'm so sorry to hear that. I/they have no idea where my coolant is going, which is why the potential cost of my repairs could be so high.

GM responded yesterday to my case and are offering me 50% of the total repair cost, which could be upwards of $6k, OR in their words "a HUGE discount voucher towards my next GM Purchase". I'll call Monday to find out all the details...and I'm sure restrictions.

But here's my thinking. Firstly, why would I want another GM product? Secondly, who would accept my trade-in in this condition, and more importantly, which undeserving fool will they sell my car, and its problems, to next? Thirdly, the value of their vehicles have plummeted so significantly I'm pretty sure I'm upside-down for any sort of trade-in value.

Good luck and keep us posted; I'll do the same.

I've these same issues for a LONG time. Overheating, using coolant (don't know where it's going), water noise, smelling antifreeze when the air or heat is on, AC spitting out the white smoke and ice chips. Nobody not even the dealership can tell me what is wrong with the AC. They just charge a diagnostic and suggest I replace the thermostat. I've changed the thermostat twice. It was over heating....I couldn't drive it a mile before it starting over heating.......blown head gasket.....almost 2k to repair. Today.....antifreeze in my passenger side floor board.....heater core.....1k to repair.....*sigh* when will it ever end!

08 equinox. Water sound in dash. After days of bleeding the coolant and pressure testing. The result was a bad head gasket. So others with this problem. Check it

I was having the same issue with the swooshing water sound and my car too overheated in 2010. Dealer "fixed it" but now ever since my heater has not worked properly. It was in service this last week and was told heater core needed replacement $1200. However, I have been fighting this issue since it was still under warranty so i refused to pay. My husband called GM motors and they will cover 80% of the charge and the dealer will repair it. Everyone should send in their complaints to GM motors.

i'm doing right now a head gasket on a equinox 2005 with 60k miles on and i notice the cooling hole in the head gasket are much smaller than holes in head and in block , i'm pretty sure the problem is coming from these too small holes from the head gasket , my point is everybody should get a mesh bigger and drill that head gasket to get a hole just a bit smaller from those on the head and that would probably fix the problem , for my case i've already put the head back on with the gasket like that but if i have to do it again i will drill these tinny holes with out a doubt !!!

I also own a 2006 and had water noise and odd smell also. Car overheated 5/2012 and was told blown head gasket at around 42,000 miles. Called Chevy and they paid $1400 of the $2000 repair bill. I had no water noise for around a year. Once the year warranty ran out noise is back! So I am worried head will go again with 77,500 miles.

I also had my power control module replaced after the car tried to start with NO keys in the ignition. It did it at dealer also. I am still having issues with car trying to start with no key in randomly usually when rainy and damp out. Chevy said they are unable to help with that. I also hear a knocking every once in a while from the rear.

Having just replaced the head gaskets AND the heater core, I can honestly say that I will never buy another American car, thanks to this Equinox (07). It has lasted for 193k miles (mostly highway), but at a huge cost in reliability and time. So far, I've replaced the following: All 4 wheel bearing modules (a couple of them twice), PCV valve, Throttle body, alternator, fan belt idlers and tightener, transmission (twice because the used one we put in fell apart), rear window wiper motor (twice) and the accelerator pedal/sensor. Surprisingly, I've had no trouble with the actual ECM or ABS even though the first error that always comes up is "Stabilitrak", which just means there is 'something' wrong in the entire engine control/powertrain system.
Right now, there is something draining the battery. I think it's the rear window wiper, because that isn't working now.
Meanwhile, when it was in my shop for a month while I worked on the heads, the parking brakes rusted up and debonded from the shoes, so when I did get it running again, it wouldn't move. I took the rear brakes apart and the parking brake linings were stuck to the brake drum/disks.
Oh, and I've replaced the brake disks 2 times (with drilled rotors so they don't warp as much). I don't consider that out of the ordinary for almost 200K miles, though.
The 3.4L engine is a royally cheap piece of junk. There is EPOXY on the block to flatten out the crappy castings they use. No wonder everyone has blown head gaskets and warped heads.
When added with the defective heater cores and god-awful plumbing system they came up with, it's a miracle any of these things make it through the warranty period outside of a car dealer's rectum.

I just purchased this car a couple months ago off a little old lady... Now I know why she was so eager to sell. I am having 90% of all of these problems as every one here. The water noise in dash, start problems, heat blows cold air when stopped or in park, thumping noise in rear, smell when turn on AC, over heats.. I took out a loan for this car, can't afford to have all this crap fixed!! Not sure what to do..
