My Altima was a two year rental. At 90000km, had crack in block between cylinders 1 and 2, likely caused by excessive heat, likely caused by hot driving and poor coolant or oil levels. There were no obvious symptoms when we bought it at 74000km. Rentals risky!
After we provided our documentation that oil changed were done properly since our purchase, Nissan Canada honoured their warranty and installed brand new engine, using old alternator, starter, A/C etc of course.
I know I posted this failure earlier, but it's worth rementioning for sure that rentals are risky, and Nissan's powertrain warranty is just what the doctor ordered
BTW my Versa was a lease return, so far so good
The compromised brake system you mentioned is truly scary!
