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. - Visitor
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. - Visitor
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. - Visitor
The light comes on only when it is extremely cold. - Visitor
It all started about 8 months ago. I felt a pulsating when backing out of my driveway first thing in the morning. This is the only time it would happen. I thought it was a break problem. Took it to my mechanic. Tests showed misfire in once cylinder but only on initial start up in morning. Chevy's suggested fix - replace EGR valve, plugs and wires. It was ok for about a week and started again. Next suggestion from Chevy - replace O2 sensors. Ran ok again for a couple of weeks and started again. This time ran a valve cleaner through and a smoke check for leaks. No leaks found. Still misfiring. 2 more valve cleaners run through. Was ok for about 3 months. Started misfiring again and now check engine light is on. Still waiting for diagnosis. Since Chevy knows this is a problem, why isn't there any recalls? My idea is because they don't know how to fix their poor design. - Visitor
gas cap not sealing throwing engine lite on - Visitor
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. - Visitor
One week (1/30/15) after purchasing vehicle, the check engine light came on. On 3/15/15, the dealer cleared the check engine light and I replaced the gas cap, three hours later while traveling out of town, the check light came on again. Problem not solved! - Visitor
