When I refuel it takes several tries to get vehicle restarted and need to pump accelerator to keep it from dying. The smell of gas is bad. Come to a red light stalls and hard to restart. Air bag light on dash and never goes out. Rpm surge and car will lunge, very scary. Just started a loud clicking/thumping noise, found out could be actuator. Ac will stop blowing cool and begin again. Repair shop can't figure out why. For a new car has many issues for being out for such a short time.
Car stalls, doesn't pick up speed, hesitates to start, engine light is on because the gas valve needs to be replaced. Gas warning comes on when half full. Gas smell throughout car. Has a load humming sound when driving or idled. Jumps when accelerate. I have taken my car to a dealership in saint louis (relocated recently) and they won't touch it.
