Drove my Honda Passport AWD 2002 about 7 miles this morning and I noticed smoke that seemed to be coming from the front wheel on driver side. What could it be?

SOURCE: Smoke coming from the drivers side under hood

could have been a little fulid from somewhere that was burning off.

Does it happen when the engine is hot and stops when you let the engine cool down? You may need to get under the vehicle to see where it is leaking from. If you dont have the means to do it safely then bring it to a shop, they will put it on a car lift. It could be a sending unit but it could be a head-gasket, valve-cover, or something else.

sounds like conveter is starting to plug and is geting hot rain was coling it off after your car is running for 15 min or so slowley put hand by tail pipe and feel vapers coming out of pipe be careful it may be real hot if it is you have a bad conveter vapers should be just worme coming out not hot

SOURCE: Heard a grinding sound under hood. Car then died.

So does the a/c still work, maybe your compressor is bad? Top off your oil and run the engine and see if you can find out where the oil came from?

SOURCE: burning plastic smell from under hood

You will need to check where the liquid is coming from, It may be anything from Air Con, Fuel, Transmission Fluid etc..

The fact you smell burning plastic could be 3 things..

1, Brake pads could smell and burn down if they are on too tight (Had this problem with a trailer). Hence when you apply the brakes it could be squirting brake fluid out due to too much pressure.
- Check brake fluid

2, If the smell and liquid is inside the car (front pass side) it could be the air ducts. Under the dashboard you have air ducts etc for the fans and in car cooling (brother had issue with this)

3, Whatever the fluid is, it could possibly drip onto something hot, unusual for liquid to smell like plastic though, Auto transmission oil smells like fish.

Best bet would be the brakes. Next time you smell it just smell in the wheel mag and see if you can smell it, check the engine fluids often and dont use A/C (Air Con) as that does drip fluid (normal). If it is the brakes smelling you will need to have the lines bled out, tyre places may be able to do this, and possibly new brake pads

Good luck
