Hi, I'm new to this site and am having serious issues with my car. Firstly a sort of rattling noise started on Thursday coming from drivers' side of the engine. Noticed the oil level was low, so replenished. On Monday (yesterday) car would not start/turn over. Couldn't jump it or bump it. Recovery came, said it wasn't the battery. Took it to a local mechanic who started it without any need for jump leads or anything.Just turned the ignition and it started. He said he thinks the rattling could be the fan belt. It drove perfectly yesterday, and this morning. Started it this evening and the battery light came on within minutes. Managed to drive it 8 miles to get home and it limped in, with hardly any power left atall. Battery light, abs light and airbag light all came on. Tried to restart it tonight and its completely dead. It's being recovered to Jeep dealership tomorrow, but would appreciate any advice as to what to expect. Only had it since August, bought second hand, no warranty left. Gutted if it's something serious!!
