Over-the-air update 661.20

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

• Improves traction and stability control when accelerating or on uneven terrain. • Improves braking and stopping performance on low-traction surfaces. • Improves the performance of assisted braking features. • The active cabin ventilation feature will operate more reliably. • Additional protection for the health of your battery and updates to help prevent excessive battery drain and overheating. • Improvements will support successful software updates for your vehicle and allow you to access new features and fixes.

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
