Does the 2021 Jeep Grand Cherokee have auto start-stop?
On some configurations. No on the 5.7L 8-cylinder, 6.2L 8-cylinder supercharged and 6.4L 8-cylinder. The 3.6L 6-cylinder is listed both with and without it, depending on the build.
Key takeaways
- Start-stop cars restart the engine many times per drive, so they are usually fitted with an AGM or EFB battery - replace like with like.
- Most systems have an off button that disables start-stop until the engine is next started; some models remember the setting.
