The fan belt started to squeak at 6,000 miles, replaced.
Fan belt started to squeak again at 10000 miles, replace.
Fan belt problems 12,000-now (39000), the belt has been replaced 6 times, I was told "it's a noise that your car is just going to make ma'am".
Engine makes crunching sound when started on very cold mornings, 37000 miles, warranty is up!
Loved the car when I got it, no problems, very reliable, and economical.
The car has gone downhill rapidly since buying it!
Once again, piston slap is the noise you hear. It goes away as the engine warms up. It does NOT hurt a thing. Your engine will NOT blow up because of this noise. Don't worry about it. I hate to say this, but "that is a sound that that engine makes".
