My wife's 2004 Solara SLE Coupe has a strange noise that sounds like it's coming from the trunk (rear end) of the vehicle. The noise is only noticeable when driving over a rough road or certain types of bumps. The noise sounds like a spare tire that's not bolted down in the trunk. After checking the spare several times to be 100% sure that it was secure (and it was), I removed it (and the cover) for a test drive. No change. The "loose spare tire" noise was still there. Has anyone else noticed this noise in their 2004 Solara? Any ideas on what it might be?
Thanks, John
