Is the 2021 Tesla Model S reliable?

Powertrain reliability is generally strong, but overall reliability can be mixed due to reported issues with trim, electronics, and occasional hardware problems. A well-maintained example with service history tends to be the safest bet.

What are the most common 2021 Tesla Model S problems?

Frequent complaints include interior rattles/wind noise, infotainment glitches, occasional door handle or window issues on some builds, and faster-than-expected tire wear if alignment isn’t monitored.

Are maintenance costs high on a 2021 Model S?

Routine maintenance can be lower than many luxury gas sedans because there’s no oil service, but tires, alignment, and out-of-warranty repairs can be expensive. Insurance costs can also be higher due to vehicle value and repair complexity.

What are the best years to buy for the Tesla Model S?

Many shoppers prefer newer years with updated hardware and remaining warranty coverage. For 2021 specifically, confirm whether it’s an early carryover or later refresh build, and prioritize condition, options, and service records.

What should I check before buying a used 2021 Tesla Model S?

Verify build configuration (carryover vs refresh), test all screens and cameras, check for wind noise/rattles, inspect tire wear for alignment issues, confirm charging performance, and review warranty status and any completed service bulletins.
