So I noticed the last couple of days the engine sounded funny upon start up - but no check engine light had come on so I didn't think anything of it...... It ran fine. Today I went out to go to work, started up (still sounded funny) pulled out of driveway, and the message board flashed - engine power reduced - and then another one that said service stabilizer - and the check engine light came on ---- I pulled over to the side of the street, turned the car off thinking something just needs to reset - tried to start it back up - and it wouldn't start........ After about 10 min - I called roadside assistance and they sent a tow truck to take it to the Chevy dealer in my area.... I have the extended warranty on the car, it has 57,000 + miles on it, I've maintained changing the oil regularly (every 3,000 to 5,000 miles) depending on highway/city mileage I've done; even though the owner's manual says I should wait until the car tells me to change the oil, and it's usually around 75%-50% according to the message center when I change it! Does anyone know what's going on with my car, as I patiently wait for the dealer to call me back and tell me what they think is wrong with it? Thanks - any help/suggestions would be greatly appreciated.
