What Happened
Your vehicle's automatic transmission software may have a problem that could cause it to shift into Sport mode unexpectedly, which could affect the engine's braking effect.
Risk if Unfixed
If this happens, it could increase the risk of a vehicle crash because the engine won't be able to slow down as quickly as it should.
Free Fix
Don't worry, it's free! The dealership will simply reprogram the transmission control module to fix the issue, and they'll do it at no cost to you.
