My Oldsmobile intrigue Sounds like jet engine when starts then sound stops coming from something in front driver side by bumper.?

That sounds like a serious issue, possibly related to your car's power steering pump or an accessory belt. The "jet engine" sound at startup often indicates a belt slipping on a pulley that's seized or very stiff. Once the belt starts turning freely, the sound stops. The location (front driver's side by the bumper) points to the area where the power steering pump and alternator are usually located.

Do NOT continue to drive the car. Driving with a seized or failing power steering pump or a slipping belt can cause further, potentially expensive damage, including:

* Power steering failure: Making steering extremely difficult and dangerous.

* Alternator failure: Leaving you stranded with a dead battery.

* Belt breakage: Causing multiple components to stop functioning.

* Pulley damage: Potentially leading to more expensive repairs.

Here's what you should do:

1. Call a tow truck or roadside assistance: Have your vehicle towed to a qualified mechanic. Driving it risks further damage.

2. Describe the problem to the mechanic: Clearly explain the "jet engine" sound at startup and the location of the subsequent noise.

3. Have the mechanic inspect: They'll likely check the power steering pump, serpentine belt, alternator, and pulleys for wear, damage, or seizing.

Ignoring this issue could be dangerous and costly in the long run. Professional diagnosis and repair are crucial.
