Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Equinox 6-cyl

  • 75,000 miles
I was driving my 2005 Equinox LX with my two grandchildren when they noticed a smell of exhaust gases in the rear passenger compartment. This was with the heating system on and in its normal configuration. After stopping I checked the exhaust system for leaks and could not identify any immediately with a visual inspection. I opened the hood and noticed the pipe connecting the egr valve to the exhaust manifold was disconnected and emitting exhaust gas into the engine compartment and intake area. It appears that the weld on the pipe boss was cracked. This seems to have occurred prematurely. After calling the dealership for a new pipe I was told by the parts department the pipe was no longer available and I would have to obtain a kit which included the pipe and a new egr valve. My question was this ever considered for a recall item as the kit is $360.

This vehicle is a joke, I already put money down on it and have only had it a little over 2 weeks. 5 days it was actually in my possession but not able to drive it much. The rest of the time it was at the car lots mechanic, it dies driving down the road, it is hard to start and sometimes won't start after 10 tries, it is shifting hard and not when it is necessary( down shifting when speeding up) and it has a horrible noise coming from the front driver side which the mechanic can't figure out. Not to mention that the fuel pump will need to be replaced thanks to the fuel gauge not working properly... I feel like I just made a very costly mistake( I still owe 6900 on this vehicle... ) Chevy should be ashamed of this vehicle and should be fixing these problems.

My Chevy has a blown head gasket after only 112K. From what Chevy mechanics have told me it's because of the faulty egr valve on the vehicles because GM failed to notify the owners of said vehicles to have them replaced. I've had nothing but problems with this car from the start. Window motors have gone bad after only 45K miles, blown gasket, the non starting, no ac unless I'm traveling down the highway, having to pullover and stop turn car off and then back on to get the heat to kick on in the winter. I've contacted GM because of the mileage they refuse to do anything at all about it. The cheapest I could find for my car was 3000 to replace the gaskets. I might as well drop a new engine in the car for that but why pay the 3000 to replace engine for it to crap out once again! wander if I could put an 08 engine in it?? never will I buy an Equinox again not in a million years.

Bought a new 2005. 2 months after warranty went out the ignition messed. Have to wiggle the key to get it to turn. Two months later the heat/ac blower control switch went out. At 120,000 miles leaking lower intake manifold gasket, fixed that. 3 months later blown head gasket, found bad fuel injector while fixing that. 6 days after all that was fixed the PCM/ECM went out, still at shop as I type. Wonder what is next. I have always owned GM products, but I believe this is my last one. I have been told by two mechanics that the bearing in motor will now go bad since water got in oil twice from leaking gaskets. 3 mechanics told me this motor is known for blown head gaskets and leaking lowing intake manifold gaskets. Online there is talk of a recall on the PCM/ECM but dealership says no recall.

Car started overheating and was diagnosed as a bad head gasket and repaired. After the head gasket was repaired the Equinox started overheating again and this time it was diagnosed as a cracked cylinder head. The motor was replaced. The replacement motor lasted 3 weeks before it failed as well with the same diagnosis as before, a bad head gasket. I contacted GM. They offered no solutions, offered no help in repairing or replacing the engine. The car is dangerous to drive and they know the engines in the 2005 and 2006 (VIN F) are bad engines suffering from a poor design. They didn't make the engines only for 2 years because they worked so well. Numerous reports about the bad engines with GM's response simply to spend more money on a car that won't last past 100K miles.

Blown head gasket at 101,000 miles. I noticed that coolant was disappearing and temperature gauge was slightly above normal. I mentioned this to the technician when I took the car in for an oil change. The technician indicated that the coolant was mixing with the oil and I should have it checked out by a mechanic immediately. I brought the car to my mechanic who diagnosed it as blown head gasket.

With only 36,212 miles on this vehicle, there is now a rear head gasket leaking. Now, as a senior citizen with a fixed income, I need to pay for this repair. It seems to me with this low mileage an engine should last longer!! poor workmanship!!!! I sincerely hope this information is shared with the manufacturer.

Equinox 6-cyl

  • 85,700 miles
We purchased a 2005 Equinox a few months ago and have only put about 1600 miles on it. We have been having problems with the engine getting hot, and the coolant being a strange orange-brown color and disappearing from the overflow tank. Took it to a repair shop on Oct. 2, 2012 and found out it has a blown head gasket. Estimate for getting it fixed is a little over $1400, and more if the head is cracked. The repair shop informed us that this vehicle has a good engine and they are very surprised that it has a blown head gasket with only 85,700 miles. We're very disappointed seeing all the complaints of other owners having the same problem and that GM is not doing anything. We will be contacting them next, even though it won't matter.

My Equinox has trouble starting and it will turn over until you give it some gas, I've been reading on consumer reports and this is a common occurrence with most Equinox's. I was at the grocery store the other day and heard the same problem with another that was parked some what close to mine as well.

  • 164,000 miles
While stopped in heavy traffic in a construction zone on I-80, car started to run very hot, fan kicked on and it finally cooled off. Upon arrival home, coolant was low, my husband refilled coolant. Called johnson motors and scheduled a check and oil change. Johnson motors service performed a compression check and informed my husband that engine was damaged and needed replaced for price of approximately $6,000 dollars (wow). Of note, in December 2010 header gaskets were replaced to a price of $1,200 dollars, I went on line to find multiple complaints from many Equinox owners concerning the same issues of header gaskets going bad and causing engine damage. This vehicle has been on a regularly scheduled maintenance care schedule with only GMC service technicians. I am shocked that with regular oil changes etc that this happened. This situation is dangerous and really needs a thorough investigation. Apparently the V6 engine used in the Equinox vehicles is a problem engine that GMC is well aware of, time for someone to make a change. Thank you.

  • 64,320 miles
My car A/C blows hot air unless I am travelling long distances down the road, heat sometimes does not work in the winter and I have to pull off the road, turn the vehicle off and then back on to get heater to work. Also while cranking the car it doesn't want to turn over at times unless I stomp on the gas pedal. This happens around twice a week. Freon is ok in my car and nobody can find the problem for A/C or the reason it sometimes won't turn over without giving it gas first. Its highly unsafe to have an air temp door not work properly as it won't defrost during the winter and won't blow cold during the summer.

Driving down the highway at about 55-60mph when the car dies. Started running again a few seconds later but then died again. Pulled over could not get it started, but started to smell something burning. Popped the hood to find the main fuse box bellowing smoke, thankfully it was raining so I let the rain cool it down. I figured this was better than it eventually catching the entire vehicle on fire as my wife and 3 kids were in the car. After the smoke stopped, the car repeatedly tried to start itself without the key being present in the ignition. It eventually stopped doing this but the dash lights would randomly flicker in unison. All electrical components were still operational (radio, lights, signals, wipers, etc...) but again no key was present in the ignition.
