2015 Legacy 3. 6r purchased 12/18/14 two major safety issues: 1) snow / water entering engine compartment while driving and causing a burning smell inside cabin and exterior. 2) water leak inside cabin at driver foot well area. Engine burning smell: 1/7 notified dealer of burning smell which appeared to be coming from engine/under car and inside cabin while car was idling. Dealer reviewed and was unable to replicate. 2/23/15 returned to dealer again, once again unable to replicate 2/28/15 3255 miles - brought to another Subaru dealer; dealer confirmed smell in writing and cited due to "rustproof coating from factory on exhaust". 3/3/15 - driving in another snow storm, smelled burning again, parked and opened hood - discovered water / snow all over engine compartment; on top of battery and covering all electrical components; have pictures. There is evidence of water stains and rust corrosion all over engine compartment, on electrical wires and the plastic white fuse connectors are discolored. Salt stains underneath engine hood and all over engine body. Standing water underneath the batter cradle as well as snow. Seems worse on left side then right but both sides have water. Engine hood is flush with bumper - doesn't appear to be any fit issue, however the only weather strip is a small piece above the grill area and does not stretch across and over the lights. 3/3/15 contacted Subaru of America and dealer - no response - yet. ****this is a major safety mechanical concern. At no time should water ever enter the engine compartment*** 2) water leak in cabin 3/2/15 discovered water leak inside cabin - driver foot well area. Notified Subaru of american on 3/2 and dealer. Known issues documented online with Subaru crosstrek and prior Legacy model years.
