Just based upon the information provided it appears that either you lost your alternator belt, or that the alternator went out on your car. (this would include the connector coming loose on the alternator)

I would suggest that you just take the battery out & get it tested and charged if possible, you'll need a fully charged battery to test the charging system and to get the car to start. If the belt is not missing or off track, when you install the battery & start the car, if the alternator light comes on, the alternator more than likely will need to be replaced. You of course could take the alternator off & take it to the auto parts store for testing while they charge your battery overnight free. (autozone & others) That will more than likely provide you with the answer to your problem. Good Luck

Whats wrong when teh hand brake light comes on when driving

Parking brake may not be fully released. In some vehicles it can also be an indication of something wrong with the braking system. You can also check your owners manual to see if it says anything about this.

Problem charing

assuming you have got a battery warning light on dash? And it obviously doesn't go out. check the large red wire at the back of the alternator with a multi meter and you should have same voltage there as at the battery and its in good condition . If you have a good voltage there and a good engine earth then you need to disconnect the small wire at the back of the alternator - that should put out the warning light on the dash, This will prove the warning light circuit is ok. As long as your vehicle battery is ok and has a good voltage the only other thing that could be wrong apart from the alternator itself is the drive belt being broken or loose.

There are MANY engine control malfunctions that can cause the engine control system to default to "Reduced Power Mode".

Reduced Power Mode is simply a computer strategy that was created by the vehicle manufacturers to keep people from doing dumb things like continuing to operate the vehicle with the "Check Engine" or other warning lamps YELLING at them to get their car properly diagnosed and repaired. Reduced Power Mode is also designed to protect the vehicle from further damage in certain cases.

Ignoring the warning lamps can cause safety issues as well as damage HIGH DOLLAR parts like catalytic converters, which the vehicle manufacturers are responsible for due to Federal Emissions and Safety laws.

As for whether it is covered under warranty....
Many major components of your engine control system are covered under the Federally-Mandated 8-Year 80,000 mile emissions warranty. The ONLY way to find out if your particular failure is covered is to have the vehicle first diagnosed to determine what is CAUSING the failure. Then you must check with an authorized dealer to see if the part (or parts) causing the problem are covered.

Brake light in dashboard coming on when driving

I am assuming that you are talking about the RED brake warning lamp and not a YELLOW Anti-lock Brake Warning lamp. If this is not correct, please let me know. There are several things that can cause this. The parking brake my not be released properly. The switch for the parking brake may be defective. Your brake fluid level could be low. (If it is, it is EXTREMELY IMPORTANT that you find out WHY!) Or you could have a brake system hydraulic failure.

In any case, it is NOT SAFE to drive the vehicle until the CAUSE has been determined. It may be safe to operate the vehicle temporarily if you find it is being caused by a defective parking brake switch, but any of the other possible causes make the vehicle DANGEROUS to drive.

Left rear brake light stopped working but bulb and fuses are OK.

These are Dual Function Bulbs. They control the Parking Lights and the Brake Lights. This Bulb is Burnt out on the Brake Coil inside the Bulb. I have actually seen Bulbs that were Bad But you could not Tell by jast looking at them. It should be fine with a New Bulb. Please Rate My Response! Thanks!
