In a piece I'm writing, a character's car starts to break down while he's driving. It makes a lot of disturbing noises and ceases to drive obediently. Despite having lived out of mine for three months, I know absolutely fuck-nothing about cars. So I was wondering if anyone knew something that could go wrong with a car that you as the driver wouldn't notice until you were on the road and had been driving for a few miles, or something that could suddenly go wrong while you were driving. It needs to be something that would manifest in weird sounds (at least as one symptom) and that wouldn't permanently put the car out of commission, and could be fixed by a competent mechanic in less than a day, preferably less than a couple hours.
Thanks so very very much!
