Defect: Terex South Dakota, Inc. (Terex) is recalling certain 2018-2019 C4045, C4047, C5050, and C7066 Digger Derrick vehicles. Due to an engine computer program error, if the hood switch fails or opens, the remote engine start/stop function becomes disabled.
Risk: A disabled remote engine start/stop prevents the digger derrick operator from shutting the engine off during hydraulic issues on the digger, increasing the risk of injury.
Fix: Terex will notify owners, and dealers will reprogram the engine computer program, free of charge. The recall began April 16, 2020. Owners may contact Terex customer service at 1-605-882-4000. Terex's number for this recall is SN682.
