FYI: the Equinox is equipped with a 3500 V6 and is made in China. It is not a derivative of the 3400 which traces its roots back to the venerable 2.8 liter V6.
beecee should not be allowed to post on the internet.. EVERYTHING beecee said is incorrect. There are NO 3500's in the Chevy Equinox. GM put the 3500 in the SATURN VUE. WOW!

I would say it's the amplifier. I had the same problem and found it was fried by some liquid getting on it. It is located under the backseat passenger side. Good luck!

If you have an factory amp in there it might be blown.

2006 Chevy Equinox has "grinding" noise coming from passenger side rear. Wheel bearing checked / changed with no change in noise. Mechanic put old bearing back in, changed me nothing for the work because it didn't fix the problem.

On here looking to see if anyone has a similar experience and what the solution may have been. Rear drum break looks fine, does not appear to be rubbing at all.

To those with head gasket issues, water pump, etc. The problem is the God awful Dex-Cool GM insists on using. Get it out of any GM product as soon as possible! Any air to it, screw up and put old "green" in, the stuff turns corrosive.

Hopefully someone on here can give me some additional ideas as to what he issue may be. This truck only has 21,000 miles on it!

I like my 2005 Equinox too! I have had a few minor stuff to deal with but I bought it used with 29,900 miles on it. With ANY car you are going to have some issues at some time or another. After all, these are machines and they need maintenance and repairs. If you don't like the car get rid of it and buy another. Guarantee you will have issues with it too! This isn't a belly aching website it is intended to be a place where if you should have an issue you maybe able to get some feedback on how to rectify it. Not a website for bitching and complaining. Sorry but that's how I feel!

I have an 05 Equinox and it rattles and clunks. The dealerships have been looking for the problem for the whole year I have owned it. Anyone else experience this problem, if so whats the solution.

I agree with the posters who claim that this is a inferior vehicle. The quality is not there. The seats do stain with only water. It's my wife's car, and while she didn't get a "lemon" persay, the car is a lemon.

I own a 2005 suburban (same year) and the quality difference is immense. Little details, like the paint on the radio controls which have rubbed off in the equinox. It's a crap car.

An update, and something that may help others. My 06 needed a carrier support bearing as it failed at about 22,000 miles. After that was replaced, the shop called to indicate that the grinding sound was still there, and requested to be authorized to open the rear end to diagnose the issue.

The bearings in the rear end were going, and apparently the dealership doesn't stock bearings, just replaces the entire unit at a cost of $2,000 for just the part. The shop quoted me a "not to exceed" price of $1,500 for the work done to replace the center support bearing as well as any and all bearings in the rear end being replaced.

All bearings have been replaced, seal replaced, and "better" synthetic fluids used to complete the job. 4 Timkin bearings that were replaced were given to me in a box to show the damage done to each, as well as the races for each.

Just some info for those who may need the "RDM" unit replaced. It is possible a transmission shop can rebuild it with a far lower cost.

I contacted GM regarding my 2005 Equinox and the problem that my private mechanic found once I complaint about the deathly smell of gas/exhaust in the car that I was experiencing over the last week. GM responded within 24 hours but since my VIN was not involved in the recall and I was not willing to travel an hour to a chevy dealer, and preferred to travel 10 minutes to a trusted and respected mechanic they cannot help me. I know my warranty has passed, I understand its not a recalled VIN auto but why can't a trusted mechanic look at it? Why did Chevy change/rebuild the pipe/PCM now differently then initially installed on the 2005 model and now with an oxygen sensor? Why weren't all models recalled?
The nearest dealer has a horrific service department and the next closet, 65 miles away, which I dealt with years ago, when I owned a Blazer and they were arrogant and rude toward me then with the same owners in charge now, would I use again? Whats a person to do? Pay my private mechanic to fix a known Chevy problem What a disgrace. This is a huge company yet they fail to take resposibiity. Shame on them. Next vechile-CHRYSLER, DODGE, FORD-NOT A chevy--worse customer service.

Fact: A small percentage of Chevy Equinox vehicles manufactured in 2005 shipped with a faulty PCM. The PCM is the "Powertrain Control Module" which controls virtually everything on your car. Think of it like Windows on your PC at home. If Windows fails, the PC can't do what it is designed to do. Same with the PCM in your Equinox. If your PCM is faulty, you will get random problems at random times - most of the time this cannot be diagnosed at the dealer because the PCM itself cannot tell them it's failing, other than complete failure.
Problems:
The faulty PCM, which is covered under a NHTSA Recall for replacement, can cause the following problems at random times:
-Failure to start
-Poor fuel economy
-Radio/CD failure
-Fuel delivery issues (engine shut-off)
-EGR issues
-misc other issues
Replacing the PCM and having your new one programmed by a dealership will solve most of your problems.
Cost to fix the PCM:
If your specific Equinox is not covered under the Recall (which some are not) you can still do this on your own at your cost. A replacement PCM should cost no more than $400.00. The PCM takes under 10 minutes to physically install, and about 15-30 to program with a Tech II scanner costing you 1 hour of labor. Suggest this route to your dealer - and if they are honest - they will understand your concerns and go this route. Find a reputable shop/dealer you trust.
Minor Problems not related to the PCM:
-Thumping sounds from rear: Rear sway bar noise. You can replace it but it's not necessary.
-Odd smells in interior: This is most likely caused by the AWD unit (physically damaged from a road obstruction, or leaking) or possibly a leaky EGR valve. Get these checked out and hire a professional Carpet Cleaning service to clean your interior after the problem has been fixed.
Summary:
In all reality, the Chevrolet Equinox is a great vehicle to look into if you are looking for a Crossover SUV. It offers a mechanically solid drivetrain that has years of dependability behind it (3400 V6 is from the 60* V6 family of engines dating back to 1980, transmission is from Aisin in Japan and also used in the Saab 9-3.) The Equinox can also tow 3500 lbs, has attractive styling, can carry tons of cargo and materials, and has more rear-seat legroom than most BMW/Mercedes luxury sedans. Granted, it's got it's fair share of problems, but don't let something like a faulty PCM for one model year (2005) scare you away from this great deal of a vehicle.
For those of you who are mechanically inclined, this powertrain is extremely easy to work on as well, similar to working with a 3800 V6 powertrain.

wow... my wife drove the equinox for 3 years with the starting problem, last year I bought a new accord for her and the nox has been sitting in the garage for a year now, I didnt want to sell it, just pawn off the pile to someone else, but its getting in my way now, so I came here do do some research, cant belive the amount of people with the same issue and the dealer played stupid with me... I will look in to getting the pcm replaced and the nox will have a 4sale sign on it.

I find this interesting because we just got a 2005 Equinox expecting the fuel mileage to be much better, but it's only in that 14 mpg range. We treat it well, it only has 55000 miles. Just replaced plugs and wires, checked the O2 sensor, but it isn't much better. I tried looking up that recall number you gave, but nothing came up. Just curious where you found it?

I am having the exact same problem with my 2005 equinox. I have contacted GM as I do not feel it should be our responsibilty to pay to replace the pipe and valve. Logically if you discontinue a part and make a "replacement" kit then there was a reason = it was faulty to begin with. I am very disappoionted with everything I have researched on GM and their customer service or lack of. I even tried to just research positive remarks and I can't find one! It's a real eye opener for what they have become. I should hear back from them in a few days. I will be sure to share my experience good or bad with as many people as I can. If it is good, I feel they deserve the credit, I've always bought GM. If it is bad, then I will be sure to share that as well. GM had earned high praise in the US and the american people have been supportive. If they can't hold up there end if the deal then I will be sure to let everyone I know be aware. I was planning on a new vehicle purchase this spring. If this isn't handled to satisfaction, I will NEVER buy GM again.

I am having the same problem with my EGR Tube (which has a crack in it), which is what is causing the noise and smell in your car. I have a good friend that is a mechanic and showed me the deal. The problem is Chevy had a problem with the EGR Tube or Valve we took the EGR Tube off in 5 minutes and ordered the new one for $55. Turns out it is 2" shorter then the original. We called back to the part supplier and they said Chevy was having major problems with the EGR Tube or Valve and now you can only buy a kit that replaces both (with the EGR Tube now shorter)for $280 and a cost of around $400 to have someone else install it for you. I am now looking on how I can get Chevy to pay the difference in cost due to it being a defect on their end. If it was not a big difference in price I would not care, but Chevy screwed up and needs to pay for it, not us. Let me know what you ended up doing, my email is: [email protected] Thanks
