I just purchased a Honda Civic 2000 and it shut off by itself?

Okay so I recently purchased a Honda Civic 2000 (1 week ago) has been driving smooth with no problems. I had it checked by my uncle who is a mechanic before I purchased it and he says the car s engine is in perfect condition, and i recently had it serviced at my local mechanic and he told me the engine is good and i had gotten quite a good deal with this car.
But yesterday in the middle of the afternoon when it was really hot i went outside to check something in my car i turned it on and put the air con on High the car was in park then after about 5 minutes the car just turned off. I wasn't too sure why so i let it rest and tried to turn it on again a few hours later and it turned on fine and this morning i had the battery checked by a mechanic and he said it had at least another 2 years worth of juice left.

BTW this is my first car and thats why I have no idea what's going on

Should i be worried with what happened yesterday?

Should I trade a Honda civic for a jeep liberty?

I turn sixteen in a month and got a '93 Honda Civic. I'm considering trading it for a '06 Jeep Liberty. Does anyone know if the jeeps are good cars or not? Some of the reviews I saw said it wasn't but my honda needs a new sunroof, paint job, and other repairs. Do you think it would be a good trade?

Is this a fair repair price for a 2013 Honda Civic?

There's a small dent and scratch on the back right corner of the car. It says that the cost of parts only totals about 100-200 dollars but the labor will take 32 hours and cost 1800 dollars. Is this fair?

How to install aftermarket alarm with power door locks?

My car has power door locks however I don't think '02 Honda Civic LX came with the keyless entry module built in. I want to put in a keyless entry so that I don't have to lock/unlock the doors with the key.

Isn't there something underneath the steering column that I can plug a "keyless receiver to?

Since I have power door locks would I still need to do wiring of some sort?

Just so you know, I'm somewhat handy and would want to save money doing it myself.

Should I buy a Honda Civic or a Hyundai Elantra?

I have a choice between a 2011 Civic with 30,000 miles for $11100, or a 2012 Hyundai Elentra with 32,000 miles for $11,000.
The Elantra has more toys, such as xm radio a usb port and audio controls on the steering whee, and is still under warranty.
The civic is still a Honda which at this point has a proven track record and to me drives a little better than the Elantra.
To me reliability is the most important, I want a car that if maintained well will last with the least amount of costly repairs. Has anyone had any experience with these cars. Which one will give me what I want. Both seem to be a good price.

My 1995 honda civic is having problems running at idle?

My car runs great when i'm driving but when i stop at a stop light, it will bog up and down. When i press the gas, it will run fine again. It is only when my foot is on the brake. It also runs fine when it is in Park. Help me please! I have already replaced the spark plugs.
