How many miles is too many for a 2018 Nissan Sentra?

The engines are fine to 200,000 miles; the early CVTs often are not. On 2013–2019 cars, treat 90,000+ miles without CVT fluid records as a transmission bill waiting to happen.

What to check before you pay

2013–2017 CVT: shudder, overheating in summer driving, whine, and outright failure; Nissan extended CVT warranty coverage on these years for a reason
2018–2019: same basic transmission with fewer complaints; still verify fluid service
2020+: new platform, dramatically better record; only minor electronics and brake-wear complaints so far
