When I go to turn on my car it does not turn on. It takes a couple tries to get the car started. On top of that problem the car is now jolting when I accelerate. I've had the car for only a year and have taken excellent care of it and beforehand it was at a dealership. I am very concerned since I have young children going in my car and it's my transportation to make my income.

Internal security system fails without notice, car wont start. Security light stays on or flashes. Car still wont start. It can be hours or even days before this problem resets and car starts and works. But then will soon fail as soon as the vehicle is shut off. Has coasted me several jobs, loss work hours, and extra money I spent on starter, but came to find out it was the security feature Chevy put in, I'm not the only one who has been having this problem.

I am complaining about the just purchased whic was vavoline when placed in vehicle engine thermal viscosity breakdown happened and engine block seized. Restarted after oil change same oil engine block seized. With what I'm reading and watching the third or fourth vehicle towed from the neighborhood maybe it's the motor oil. I understand that high heat breaks down rapidly with soy based lubricants. I understand you might not be able to admit this or are unaware but could you please keep on file.

The transmission started to develop a shudder at 140000 miles. I have taken it in multiple times to get looked at. The las resort would be to get a new transmission. This issue causes the car to not take off right away or shake pretty bad making it seem or feel that it will stop, shut down, or jam up even while driving down the road. I have read that this is a common problem with this vehicle model. It happens at stop lights, while running, and while turning. Please investigate this matter before many people waste thousands of dollars trying to investigate this issue. Thank you

175555 miles fuel smell and fuel loss when car is running. Rough start, some missing. Fuel filter failed at filter inlet spraying gas onto underbody of car so didn't see the fuel spill. Replaced filter and O rings.squealing belt sound at start up. Serpentine belt tensioner broke, replaced tensioner and belt. No check engine warnings, no electronic gauges I have the basic Impala model. Watched the fuel gauge drop by lines while driving and smelled gas when shut off car. Fire hazard, and engine failure if the belt broke completely..another 300$ spent

When starting the vehicle, the engine intermittently starts, runs rough/sub idle then stalls. When the engine starts it seems to run normally, but on at least three occasions, while driving the vehicle the engine would stall and I would loose power steering and brakes. I took the vehicle to jeff wyler Chevrolet for repairs. They had this vehicle from Jan 21 - Feb 11, and replaced the body control module at a cost of approx $435 dollars. When I started the vehicle the conditions remained the same. I subsequently took the vehicle to an independent repair shop (kt automotive llc). They replaced the ignition switch and condition was corrected (approx cost $180 dollars). Note; this condition existed with multiple or no additional keys on my key ring. On 17sept GM recall 14350 was completed on my key(s). Given the experiences described above, this recall will not correct the faulty ignition switch defect on this vehicle.
