I recently bought a 2014 Lexus RX350 from a dealership. About a week ago, I noticed a slight dip in the driver’s and passenger’s sides, but the floors never get wet. The only rust I’ve found is on the undercarriage, specifically the muffler. The car was originally purchased in Palm Beach, Florida, and has been in Alabama ever since. Is this a common issue with 2014 Lexus models, or could it be a previous leak that I’m unaware of?
