2008 Saturn VUE XE 2.4 litre automatic 2.500 miles. Traction control "OFF" illumnated, service engine light on, airbag light on, tranny in limp mode, engine continues to run for 10-15 seconds after ignition is shut off. Dealership has replaced ignition switch and fuse box, but this did not change anything.

SOURCE: car won't start

Only a few basic things are necessary for the engine operation 1. Fuel (To be exact proper air/fuel ratio, normally it is about 14/1)
2. Spark (in appropriate moment)
3. Proper timing (the valves should open and close only in appropriate time)
4. Compression in the cylinders (Normal compression is 120 - 170 psi. The engine won't start if the compression is lower than 70 - 80 psi.)
Plus, to start the engine, the battery, the starter and the starter circuit should be OK.

If the engine won't start - there's no magic - one of these things is probably missing. Most often it's a spark- or fuel- related problem, but often it could be very simple things like dead battery.
If the car won't start, check simple things first:
Make sure you have a fuel in the tank, oil in the engine and the battery is OK, follow this link - How to check the battery
Now simply answer the questions, press "Yes" or "No" (If it's blue, follow the link).

- Do you hear the cranking sound when you're trying to start your car? (Yes No )
- When you switch the ignition ON before starting a car, does the "check engine" light come ON? (Yes No )
- When you switch the ignition ON, do you hear fuel pump buzzing sound from the gas tank area? (Yes No )
Before your engine died, did you experience any prior events such as:
- leaving the lights ON overnight (Yes No)
- driving through a deep puddle, or washing the engine compartment? (Yes No)
- trying a jump start? (Yes No)
- having only a little fuel in a tank? (Yes No)
- having had the engine repaired recently? (Yes No)
- the engine was overheated? (Yes No)
- extremely low oil pressure? (Yes No)
- unusual noises such as knocking, pinging, whistling? (Yes No)
- smoking from exhaust pipe? (Yes No)
- strong smell of a gas? (Yes No)

Now, let's try again. Turn off the radio, try to crank the engine one more time, and listen carefully. Is the cranking sounds different than it used to be? If it's different, does it looks like the engine being cranked by the starter too slowly? (Yes No)
Is the engine being cranked too fast? (Yes No)

Hope this may help;

Hate to be the bearer of bad news but mine failed at 29K and became undriveable at 31K and after years of hard handling, I treated that car like it was Christmas tree ornaments, fully expecting it to last until I am dead; the engine failed at 57,600. It's gone and I'm still breathing. It was the last GM anything I will ever own.

Here is the definition of the code in GM manual:
P0128 - Coolant Thermostat Below Thermostat Regulating Temperature, this indicates the engine is running cold, u need a thermostat

SOURCE: 2005 Saturn Vue - Airbag dash light intermittently on

THE AIR BAGS TURN OFF AND ON BECAUSE IT GOES BY WEIGHT... AND IT ALSO GOES OFF WHEN YOU ARE GOING A LOWER SPEED AND WHEN YOU ARE GOING A HIGHER SPEED THEY WILL COME BACK ON.

The torque converter clutch circuit may be at fault. The best way to determine the problem is to have a scanner/computer to read check engine codes.
