I have a FIAT 500, which I bought new last September. About one and a half months ago I took it into the garage as it was making a high pitched noise and had a lot of general running noise when I drove. The FIAT garage couldn't find anything wrong, so I carried on. Last week I was driving from North Yorkshire down through Leeds and the high-pitched noise started again. I just dismissed it as FIAT said it would be nothing. As I carried on towards Birmingham there was a clonk like something was falling off (I didn't hit anything in the road, I am certain). Around 10 miles or so after that I had a blowout while I was in the outside lane of the M6. Luckily it wasn't that busy. However, I pulled over and the AA came out and put the space saver on. Around 25 miles or so after that, the high-pitched noise started again, so I slowed right down to about 25mph (knowing I couldn't go faster than about 40mph on the space saver anyway) and the noise seemed to calm down. The next day I took the car into a FIAT garage but as it was a Saturday there wasn't anyone to look at it, so I arranged for the wheel to be changed. This was done. All seemed fine until yesterday when I drove about 6 miles and the car started making the noise again. This time I pulled over and looked. The driver's wheel was red hot. Far hotter than the passenger wheel. I told the FIAT garage all this and they don't seem to be taking it very seriously. They suggested I bring it back in two weeks (as that is when they will have a spare car for me). They now want to charge me to strip down the brakes. Is this right? The car has only done 10,000 miles and they are not worn.
