My friend had this problem with her Hyundai 2003 Sante Fe...just dying out. And I did some research for her. There was one particular forum, where I Googled the make and model, year of the vehicle that came up where a few people had this problem. And the problem isn't picked up by the dearler's computer test. The part was the EGR solenoid control valve. Maybe that's a place to start?

As long as you have BOTH alternator bolts loose, you just "pry" it until the belt is tight.I say "pry" but of course you dont want to be TOO rough with your alternator! They dont have an actual tensioner!Good luck

lol no but you can always try a safety pin in place of the switch

Do you have a CEL on? Your 02sensors could be all whacked out causing too much gas to burn.

Yes , almost all newer cars have internal regulators . Make sure the belt is good also .

There is a spring loaded belt tensioner, use a wrench to deflect it and reinstall the belt.

Have you checked the sensor?

this sounds like the belt is worn and needs replacing.when its damp and cold if the belt is worn it will slip easier under this condition than in warmer weather.also the belt tension may not be proper.if this has a belt adjuster that you can adjust then the tension may need to be tightened.if it has an automatic belt tensioner(one that adjust tension all the time)like a serpintine belt then the tensioner may need to be replaced as the spring that crates the tension do get weak over time.

you don't have to take the oil pan down its located if looking at the engine top view its to your far left under the alternator and I have a feeling your going to be replacing that a lot there's been problems with that type of oil pump

Yes these do happen with the a/c on the condensor gathers heat,thats why the cooling fan is suppose to run when you have the a.c on.You solution is to inspect that the radiator fan goes to high speed,when the a/c iscommaned on.if it does not come on further inspection will be required of the operation of the radiator fan.

A turbocharger can leak. Some of the gaskets might be shot and need to be replaced or a hose might need to be replaced. If the turbocharger itself is leaking and not a gasket then the turbo housing is probably cracked. If you get the turbocharger replaced it should last a good 20 years or so. The only thing that usually wears out on turbochargers are gaskets and thrust bearings.

The service manual with this information in it is copyrighted and you must purchase it either used or new from the dealer, it is not free to share on line. Sorry.

try using led lights because of there lower usage of power.

1. Some cars, this is normal. Like the passenger side airbag is only active is someone is sitting there.2. Only the dealer should look at this. It is a huge liability for anyone else to mess with and for the dealer. He may fix it for free.

EVAP purge/vent solenoid circuit condition. the PCM has determined that a malfunction exists in the electrical circuit for the vent valve/solenoid in the evaporation emission control system (EVAP)

First see if you are getting spark at any of the sparkplugs.

If it came off regulator track it is possible to repair first you must remove window brackets from window regulator clean off all old adhesive and use jb quick to secure them back to window it is a little tricky but if you get it right it does work

Could be numbers of things, get your self a bottle of fuel injector cleaner, pour all of it in the gas tank, and fill up with high octane 92 or 93, run it for while and see if change anything. Prob: Bad O2 sensors. MAP sensor, dirty plugs, bad/clogs injectors. If you have a high miles 100k change wires,plugs, good tune up would be good.
