What Happened
The start-stop accumulator is a small part in your vehicle's automatic transmission system. It helps your engine and transmission work together smoothly. In some 2018-2020 models, this accumulator might be missing a few essential bolts.
Risk if Unfixed
If the bolts are missing, transmission oil could leak out, and you might lose power while driving. This could increase the risk of a crash, especially if the leak ignites a fire.
Free Fix
Your dealer will inspect the start-stop accumulator and replace it if the bolts are missing. This service is completely free, and you should schedule it as soon as you get the recall notice.
