Dealers will inspect and replace the front brake modulator valves, as necessary. Some vehicles will have a software update which will alert driver when a replacement is required. All repairs will be performed free of charge. Owner notification letters were mailed beginning October 16, 2023. DTNA's number for this recall is FL-958. This recall expands and replaces previous recall 20V-390. All vehicles previously repaired under recall 20V-390 will need to have the new remedy performed.
