Safely pulled over when I could, it was at a ford dealership. They told me there was a local Chevy place, went there, only 2 guys in service dept. doing oil changes only, no help, I was told to bring it back. When I left the Chevy place to go home, the car seemed to be fine, but did have the engine light on. Last night went to go to work, night shift, I guess it reset itself. No signs of anything wrong. What is going on ? What do I do ? My Chevy has on 38,000 miles on it. Is this covered by chevy ? Help!!!

It happened again a month later, almost stranding my daughter-in-law on a busy highway. We took it in again and they could not figure out why this continues to happen. They're not able to replicate the issue, they drive it for a few days and all seems to be working. The 3rd time this happened the message came on again to service Stabilitrak, the check engine light came on and the car had almost no power. the engine continues to run but we could not drive more than 25 miles per hr. We luckily made it to the dealer and kept the engine running. They could not read the error code using a portable diagnostic reader so they kept the car and replaced the throttle box. Again, hoping this would be the answer. Yesterday the car began shifting gears really hard and bam...error message and loss of power again. We let the car sit for an hour and started it again. It seemed to have some power but after driving it a few miles it loss power and we coasted off the highway (I10 in Houston I might add which was extremely scary!). Let it sit again for 20 minutes and the car started up again, no Stabilitrak error but the check engine light is on and RPM's were running high. We pulled off the highway to fill up and the care & ran OK, although a very scary few miles on a busy interstate. We are taking it back to the dealer service center again but would like to hear if anyone else is experiencing the same issue. I owned a 2007 Equinox and I loved it prior to purchasing the 2010 used with 23k miles. I don't put that many miles on my car and take very good care of my vehicle. We've always been a Chevy household but I am extremely frustrated and disappointed with the problems we've been experiencing and the fact that even the dealership isn't able to fix it. I am crossing my fingers but have little hope they will figure it out. Not sure we will invest in Chevy ever again.

The RPM's were also jumping from 700-1500 while idling. These symptoms would happen sporadically and didn't really seem to have any type of pattern as to when it happened or why. I do know that the engine power cutting out while I was driving down the interstate at 70 mph was not the safest position to be in as the car fell from 70 to 40 and there was nothing I could do about it.


I had the codes read at AutoZone and it came back to the EGR valve, $90 for the part and a few bolts later I was able to change it myself. Unfortunately this did not fix the problem.


I did some research online and I convinced myself it was the "throttle position sensor" which in an Equinox is part of the "accelerator pedal position sensor" - $70 for the part and a few bolts later I was able to fix it myself. Again, this did not fix the problem.


On the advice of a buddy I added dry gas and Sea Foam to a full tank of gas. While the car was still sluggish it felt like it was getting progressively better and the warning lights were off. I was able to burn off the tank without the issues resurfacing. However, I refilled my tank - added another Sea Foam, and the following morning I am back where I started. All of the lights are on and the engine power is reduced.


I am at a loss. I am completely defeated with this problem and totally abandoned by Chevrolet. In reading and researching this is obviously a common problem with Chevy, but no one seems to have found or posted a concrete solution.


If I find something that works, I will let you and everyone else know. If you get any type of answers, I would whole-heartedly appreciate your feedback.


I, like you, am ready to take my money elsewhere.
