No power in the car, except airbag light is on. Jumping the car did not help. I purchased a certified car with 35k miles, 3 days ago. Any suggestions?

 

Immediately stop messing with it.
Have it transported back to the place you bought it, it is under warranty.
That is the reason you buy a "certified" vehicle.

 

Yes, take it back under warranty.

Also, double-check your bumper to bumper so you know when it ends.
the powertrain warranty should be 7 year/100 k miles.
The bumper to bumper extended can be confusing as to what date and mileage it expires. Check your CPO extended warranty card for dates/mileage.
For instance if the car was 3 years old with only 10,000 miles, the warranty expired and the CPO warranty only gives you 12 months/12000 miles on top of that. So at 22,000 miles the warranties up.
Or if the vehicle was 2 years and 6 months with 40,000 miles and expired , you only have until 3 years 6 months til the CPO is expired.

 

Like others said, send it back to the dealer. They are liable for repairs.
