The CVT is quiet in the data — and has no warranty extension behind itmoderate
- 2.0L four-cylinder
There is no transmission cluster on the 2023. But two filings are worth noting rather than dismissing. In one, an owner reports a delay in acceleration after the car has been idling, and writes that during a test drive the dealership's service manager "acknowledged that the issue was caused by the updated CVT transmissions and stated that it would be best to return the car." In another, an owner reports the engine seized at roughly 100,000 miles and replaced it with a used unit from a salvage yard. Neither is a pattern on 18 complaints. The context that matters is that both Nissan CVT class-action settlements stop at model year 2019, so a 2023 has no extension at all — just the original powertrain warranty, which on an early 2023 is running out. Nissan has published a belt-and-pulley sub-assembly service kit and an engine-support bracket covering 2020–2024 cars, which is tooling built for a component that gets replaced. A mechanic channel covering this generation estimates CVT trouble between 30,000 and 80,000 miles at $3,000 to $5,000 to replace — a transcript figure, not a Nissan price.
