POWER TRAIN:AUTOMATIC TRANSMISSION
Manufacturer

What Happened
The start/stop accumulator in your car is a small part that helps your transmission work smoothly. In some affected models, this part might be missing a few bolts that keep it secure.
Risk if Unfixed
If the bolts are missing, transmission fluid could leak out, causing your car to lose power and potentially stall. This could increase the risk of a crash, especially on the highway. In rare cases, a leak could also lead to a fire if it's near an ignition source.
Free Fix
Your dealer will inspect the accumulator and replace it if any bolts are missing, all at no cost to you. Just schedule the repair when you get the recall notice and they'll take care of it.
