On the 2021 Porsche Boxster, if you own a 2021 Porsche Boxster in 718 Spyder or Boxster GTS 4.0 form, NHTSA recall 21V200000 applies to you. Porsche found that the engine's connecting rods may crack and loosen. A loose rod connection while driving can damage the engine, cause it to stall, or produce an oil leak — NHTSA's stated consequence is an increased risk of a crash or a fire. Because the failure is inside the engine, there is no owner-serviceable check; whether a particular car is included is determined by VIN. Porsche's internal number for the campaign is AMA4. The 193-vehicle figure NHTSA publishes is the total for the entire campaign, covering the 718 Spyder and Boxster GTS 4.0 alongside the Cayman GT4 and Cayman GTS 4.0 — it is not a per-model number.

Common Symptoms

  • Engine stall while driving
  • Oil leak
  • Engine damage

How to Fix

Take the car to an authorized Porsche dealer; the work is done free of charge. The dealer replaces the connecting rods, and replaces the engine if that turns out to be necessary. Owner notification letters went out May 21, 2021 — a second or third owner of a 2021 718 Spyder or Boxster GTS 4.0 may never have received one, so verify the VIN directly at nhtsa.gov/recalls. Porsche customer service is at 1-800-767-7243 (recall AMA4). Because a failure can stall the car or start a fire, this should be handled before further driving rather than at the next service.
