Hello,

Purchased 2011 Equinox last month.
Driving to work, a warning came up on the DIC, regarding: "AC turned off because of high engine temperature", (The outdoor air temp was 5 degF) and the analog temperature gauge was no longer reading properly. Stopped and checked engine, and it was not overheating. Contacted On-Star for a diagnostic, that was a joke, I hung up after 15 minutes because I had to get into work. Took vehicle into dealership, and was informed the ECM went bad and it would take a few days to get the part in. I was issued a loaner vehicle, and would wait for the part. Fine, no big deal, until . . . I received a call from dealer this morning. Part is unavailable until March!!!! You have got to be kidding me, but he was not. GM does not have an ECM module for the Equinox available until March, or possibly in two (2) weeks at the earliest. That is ridiculous. It is very obvious that GM is putting everything into production, and is not considering the customers who have purchased a vehicle in good faith, and expect top notch service after the sale. I fully understand that things can go bad, but to take a month to get a replacement part for a 2011 model is pathetic at best. Extremely disappointed in GM's concern for its customers after the sale. Will have to seriously think about this incident when purchasing again. The vehicle only has 1,300 miles on it; now reliability concerns, and the ability to trust the vehicle are developing. Hopefully this is not a lemon.
GM needs to step up to the plate.

Although a different part, I had the same problem a number of years ago with a Honda Accord. The dealer, rather than have me wait a couple of months for the part, took the part off a new vehicle on his lot, installed it in my car and just marked the other vehicle as "sold" until the part came in, then put it back on the market. Now this is a dealer that won wants, not one that leaves the problem with the customer.

Seems to be a rash of this same problem happening recently. Although I believe in other instances they were able to re-flash the ECM. Did the dealer give you any indication that they at least tried to do this?

So does this mean your vehicle will sit at the dealership for two months?? That would not make me a happy camper either!

I am fairly certain you can't do this with an ECM, since they are now VIN and vehicle specific. Sorry to hear about your Equinox :(

This is not an ECM failure. It is a known failure. Your computer probably only requires a re-flash. It happened to mine and required about 1/2 hour of the dealers time to fix.

But does a re-flash permanantly fix the underlying issue?

Thank you all for your responses.

I am in contact with GM Customer Service, and am hopeful that this issue will be resolved sooner than later. I have no issues with the dealership, they tried several different things before coming to their conclusion. To take a month to get a part; especially with a current in production model is ridiculous. Hopefully GM Customer service will come through.

I will update when I have more information.

What did they claim they did to check it out? This is a well known issue on here and a basic simple battery disconnect at home, or a reflash fixes the problem and so far it never happened again with either method. I had that glitch at around 12k miles and I have over 54k now and it never happened again and I did the battery disconnect method.

Hello everyone,

The part came in yesterday morning, the Equinox has been fixed and returned. According to the service invoice, the ECM was replaced, and programmed.

From one month to one week, a significant improvement. GM customer service informed me that the dealership got the part, and the 'Nox was repaired. Sure enough, I checked my home voicemail, and it was ready. So far so good, it is running well.
Thanks to GM customer service for their assistance, and good luck to those with similar issues.

I wonder if somewhere in all this the dealer screwed up the ECM while trying to do a flash???
Seems strange everyone elses vehicle with same problem has only taken a 15 minutes flash of the ECM..
