Mercedes-Benz USA (MBUSA) is recalling 28 model year 2019 AMG GT63 4MATICs and AMG GT63S 4MATICs.
A wiring harness for the automatic transmission may not be properly secured, allowing it to chafe against the drive shaft and possibly cause an engine stall, which increases the risk of a crash.
What to do
MBUSA will notify owners, and dealers will inspect the mounting clips and wiring harness, and repair or replace them -- as necessary -- free of charge.
The recall is expected to begin March 27, 2020. Owners may contact MBUSA customer service at (800) 367-6372.
