  • Gas cap throws on Engine Light....purchased an after market cap, light came back on. Problem resolved with a cap ordered from a Chevy Dealer for the exact year, make and model......light never came back on.

    Engine light coming on and every time we take it to dealer the say is faulty gas cap. Replaced and is ok for about a year and then light comes on and cap is loose and will not tighten. I replaced two since purchasing new in 2007. Is there a better cap I can purchase I have always bought from dealer.

    Found cheap gas...so I bought it . Shortly after using only this gas the check engine light came on.switched back to my regular gas and tightened the gas cap...went away.comes on usually after I get gas. I changed caps but the new one would not seat properly so the light came on again. I took back the new cap, and used the, older one but cleaned it we'll along with the port. The light went off and has stayed off. I had AutoZone scan the OBD... and it stated there was a large leak. Gas cap was the first reason!!!!!. I will never buy another chevy... they cannot seem to engineer cars the way they used to. All of the problems we have had are related to miss poor design and engineering. The ignition(470.00),CD player,Windows won't go down or up, ac works when it wants,the list goes on and on. I take care r e and change my own oil etc...now I have to remove engine parts to change the plugs???. The brake sensors are shot also, Nd, this is a known problem. Instead of waiting for class action litigation, maybe chevy or GM should do the right thing and just take care of the problems instead of denying all the posts about common issues COMMON PEOPLE have.

    Received several messages about the gas cap being loose. Tightened it every time. Then the Check Engine light came on due to loose gas cap. Took it to the dealer. They replaced the gas cap. Check Engine light came on again about a week later. Dealer replaced a valve in the fuel system. Picking the car up today, so don't know if that will be a permanent fix or not.

  • Had to go thru emmisions testing and the light came on a day before! Was told to relace gas cap with one from the dealer. Paid twice as much for it but it fixed the problem.

    light came on about a month ago then put gas in and it went off. Just the other day it came on again. Not very many miles for this to happen.
