Manual Transmission problems of the 2002 Mazda MAZDA6

2002 Mazda mpv transmission and water pump went out at 58,000 miles. Not under warranty and Mazda will not accept any responsibility for the repair. The car just died in rush hour traffic, and luckily no accident occurred. The fix was $4,000 in repairs paid by me. Six weeks later, I am told that I have to replace a coil and spark plug for another $500. The mechanic even said that I may have to replace more coils in the coming months.
