2003 Nissan Altima exhaust system problems

2003 nissan altima exhaust leak positive for carbon d in my blood many problems with engine light coming on with the first year of owning my car it started with instructions on how to screw a gas cap on to after years of attempts trying to convince them it caused damage to my lymph nodes in my lungs when it was too late and they saw visible signs inside my car like black soot and a strong smell they laughed and said hey lady you have a leak they replaced the catalytic converter and the o2 sensor within 6-8 months…

The contact owns a 2003 nissan altima. The vehicle started to make noise in engine after oil change. Two days after oil was topped off, oil level showed it burned 4 quarts with no leaks. Since, it has consumed an excessive amount of oil. The low engine oil warning light illuminated on the instrument panel again. The contact placed more oil into the vehicle before it was taken to a repair shop. The mechanic verified the low oil level and vehicle was burning oil at an alarming rate.
