It's probably your alternator. I'm a mechanic and my girlfriend drives this car. She has put in four replacement alternators. When her new alternator is going bad, her engine sounds like a diesel truck. This model year toyota, came factory with a bad part. Only certain vin numbers are incorporated. Toyota released a technical service bulletin (T-SB-0004-11, date of issue January 5 2011) that under warranty, covers cars under 3 years or 36,000 miles. "Some 2009-2010 model year Corolla vehicles may exhibit a condition where the charging system light is "ON", the alternator is in operative, and/or there is abnormal noise from the engine compartment. This may be cause by the pulley not being seated correctly. The pulley has been updated to correct this condition. Use the following procedure to diagnose and repair the alternator." This is from the online repair manual we use at my shop. Toyota has engineered a new part, however, you can only buy it from Toyota, as they have not released the specs. If you go to an auto parts store to buy a cheaper part, they will sell you an alternator that was to designed to fail. I am speaking from experience.
If you plan to trade your car in, as a mechanic, I would refer you to a Honda dealer or private owner. I always have, and always will own a Honda. Parts are cheap, available and long-lasting. Honda also continue to hold the highest resale value. Something to think about if you don't plan on owning a car forever.
PS-I do NOT work for Honda. This is not a plug.

'06 Civic LX and still am very happy with the car. Sure there have been some TSB's done and a couple other little problems, but with a 1st year model, one expects certain things will crop up. And not really sure what else I'd buy as a replacement for it? Especially in it's price range. And to be honest, I couldn't justify spending C Class or 3 Series $ on a vehicle no matter how well it drove. As much as I love cars, just couldn't spend that kind of change on a vehicle.

I had no noises or symtoms whatsoever before water pump was replaced. The car was in for state inspection and my warranty was about to expire; the Toyota dealer suggested they replace the water pump just in case it was a bad one and it possibly might cause a problem after the warranty expired and they didn't want me to have to pay for it.
This is the difference between the two dealers. My dealer actually looked out for me where as your dealer couldn't be bothered.

I did show a mechanic (friend) checked whole system, nothing wrong. He said might be some thing out of position inside the engine, also mentioned about this pulley. Contacted regional office, they recommended to check with another dealer.
Toyota dealer quoted 10,600 (2009 with 23K miles). I like the car, quiet, smooth and 35mpg highway. I will wait for 2014 corolla or buy 2013 Accord. For Honda, Material quality is excellent but road noise is still major issue. I am leaning toward owning a Honda for the fist time

Excellent price and low mileage but maybe they're low balling it because of the problem. Are you sure it's road noise your hearing and not the engine noise? I don't hear any road noise from my 2009. Are they giving you a certified warranty with it? Either way, Toyota or Honda you can't go wrong.

No. that’s the price they quoted for my car. I decided not to trade in. Very hard to find a good car for 10K. Next Week I will take my car to another dealer . Right now not a major issue. It might be the pulley.

I know this is an old post. I hope you solved the problem by now.
I am not a Toyota owner. But my neighbor is having the same exact issue during dewy mornings or after a rain with her corolla (late 90? model). She would crank the starter 50 times or more before it gets going. This repeated starting attempts are very annoying and I almost want to volunteer to fix her corolla so I don't have to see her having the starting issue.
I had exactly the same symptom with Volvo 740. During the wet weather it wouldn't start. But later in the day it would start up like nothing happened, and once it starts up the car ran fine without any issue whatsoever. But the morning after the rain was the worst. I was expecting not to start on those mornings.
The solution with Volvo 740 was Fuel Pump Relay. The Relay will short with excess moisture, hence the fuel pump will not work. As the day warm up, the moisture disappears and the relay will function properly.
I replaced the fuel pump relay on that Volvo, and the problem was gone. Gone forever.
For your info. In Toyota vehicles, Fuel Pump Relay is called Circuit Opening Relay. The relay costs less than $10. Even if it doesn't work, it's worth a try, don't you think?
#972 of 1009 Air-Conditioning Issues on 2008 corolla

I have been having issues with the air-conditioner on my 2008 corolla, sometimes it cools and sometimes it does'nt. I replaced the AC relay and the issue appeared to have been sorted out but it started again after a while. Anyone has any clues what the problem could be?

Has anyone checked the refrigerant level? Also, it's important that the cooling fan blow across the condenser at the appropriate times. So if your car has 2 fans, one for the engine and an auxiliary for when the AC is on, be sure that second fan is kicking in.
If none of those ideas work, you may have to have the car scanned for trouble codes, or taken to an AC specialist---perhaps you have an issue with the orifice/expansion valve (not sure which system your car uses).
