I own a 2003 Nissan Murano. Lately I have noticed a fluid leaking from the rear of the car by a bracket on the rear axle. It is dirty and oily and smells of rust. Do you have any idea what it could be? I asked my mechanic and he said it wasn't a problem, but the leaked area on the garage floor is expanding. Thanks, Debbie

Bogi Lateiner, Owner and Technician at 180 Degrees Automotive Hi Debbie - I would bring it to another shop for a second opinion or ask the mechanic you brought it to, to tell you what it is, not just that it is nothing to worry about. In may in fact be of no concern, but knowing 'what' it is that you are not suppossed to worry about might help :) That being said - there are a few things that could be leaking in that general area and with out seeing it is hard to tell. It could be condensation from a hole in your exhaust, fluid from the differential or from a brake line. If the puddle is getting bigger and it concerns you - bring it back or bring it to someone new. Good luck - hope that helps! Bogi Lateiner 180 Degrees Automotive, Inc.

Laurie Sarno, Co-Owner at Super Girls Auto Hello Debbie- it could be 2 things- 1) if this is an AWD model the rear differential maybe leaking-2) it could be condensation from an exhaust system that is cracked or starting to rust out - hope this helps- thanks Super Girls Auto.

Suzanne Grego, Technician at City of Philadelphia Fleet Management Debbie, It's hard to be sure what is leaking without a visual inspection. I would suggest that you get a second opinion from a qualified technician that can explain to you exactly what is leaking. In my opinion, especially on older vehicles, some seepage is normal and usually not worth disrupting. However, if it is enough to notice on the ground after being parked for short periods, it needs to be investigated further. Suzanne
