The check engine light was on, I took to dealer for service; it was a short in fuel pressure sensor. It took 4 hours to be replaced and the check engine light went off. I started the car later and it turned back on. I was told that it is normal it needs to reset.
Do you
have the same problem?

Hi,

If the light went off after the repair, it shouldn't have turned back on. Oftentimes, the codes need deleted or erased after repairs, but if it was off when you got it, it sounds like that was done.

Here is what I need you to do. We need to determine if the same code has returned or if there is a new one. Here is a link that explains how it's done. However, if you take it to a parts store, most will do it free of charge.

Here is the link:

Let me know what code has set the light to turn on. Also, if you look at your receipt, it should have the original code or codes found. It should start with the letter P followed by 4 numbers.

Take care and I'll watch for your reply.

Hi,

With your neighbor's scanner, clear the code and see if it returns. If it does, then the manufacturer is responsible for repairing it. If you want, I attached the diagnostics below for this vehicle. Take a look through them and let me know if you are comfortable performing them. Also, be careful because a dealership may give you a hard time if something fails. If they know you worked on it, they could decline a repair.

Let me know what you find or if you have questions.

Take care,

Joe

I called Chevrolet service this morning, they told me that the computer will reset after a number of drive cycles. I don't know how true that is. Thanks for the help on this matter.

Hi,

If power was removed, there is a drive cycle that goes through to test different circuits. However, it shouldn't turn the check engine light on until something fails; especially since the light was off when you got it and it came back on.

If the vehicle is running properly, entertain their idea. See if it goes off. Hopefully, it will, but since it turned itself back on, I suspect it won't.

Or you could try clearing the code with the scan tool to see if it turns back on. If it does, then suspect the problem still exists.

Let me know what I can do to help.

Take care,

Joe

Hi,

Honestly, a day off has to be spent at the dealership. Ugh! Remember, they have three chances to fix it. One down already. If they can't fix an issue with the fuel pressure sensor, it could cause issues that may put you in danger.

If that is the case, after three attempts, you can claim the Lemon Law and force GM to buy back the vehicle.

Let me know if there is anything I can do to help.

Take care and good luck.

That's what I thought. They didn't fix the problem. They may believe they did, but something different may be causing it.

I look forward to hearing the results.

Take care,

Wanted to update you.
I'm really ticked off, I brought car to dealer this morning. I sat there for 3 hours service person told me it's going to be a while they are busy; we will call you with an update. So, I left I called them about 5:00pm and they told me they had not even looked at the car yet. I'm really considering bringing it to a local mechanic I feel they are messing with me because the car is under warranty, and they don't want to be bothered. Maybe I'm wrong.

Hi,

Hang in there. Even if it is a warranty repair, they get paid by the manufacturer. Did they let you know if they can get to it tomorrow?

Let me know.
