2008 Nissan Altima Sedan 2.5 S 4dr Sedan (2.5L 4cyl CVT)
own 2 of them same year and model
 Both cars have reached over 110k. Reliability plummets after getting above 110k in one of the two cars. Stearing column went at 103K and it was 1300 to be fixed at dealership. Car wouldnt start. Now same car needs to be towed but due to lock on parking button. We maintain them well with synthetic oil changes and routine maintenance. They go through batteries quicker than they are supposed to.   but not the level of Honda I owned in the past. The more reliable vehicle,  master brake cylinder went out at 70k. 800.00 repair.  Both had batteries replaced X3.   Of course usual brake pads, etc.  I was happy with these cars until reaching over 100k. Now a days with toyota, honda, gmc, you get to about 200k miles before having problem like these. My 2002 Honda Civic went to 170k before any repairs and sole at 213k. The car having problems is mostly highway miles. I just purchased a toyota product and both of our nissans will be sold in the next year!
