GM has issued a new Service Update describing a remedy that is now available for certain 2024 Chevy Blazer EV and 2025 Chevy Blazer EV units that may have missing plugs in the rear chassis harness.
Affected Chevy Blazer EV crossovers have cavity plugs missing from the rear chassis harness electrical connector, according to Service Update number N242468490.
The service update does not indicate any symptoms or consequences resulting from the missing wiring harness cavity plugs. However, it contains a fix which is to be applied by dealership service personnel on any involved Chevy Blazer EV unit brought to the dealer for any reason, or currently in inventory.
Service technicians are instructed to inspect the vehicle. If any harness plugs are missing, new plugs should be inserted to bring the chassis harness up to spec. This fix is available free of charge to owners through the end of the specific Chevy Blazer EV unit’s New Vehicle Limited Warranty Period.
As a reminder, pricing for the 2025 Chevy Blazer EV starts at $45,995 for the LT trim with FWD and rises to $56,990 for the RS trim with RWD. New for 2025 is the high-performance Chevy Blazer EV SS trim level, which recently began appearing at dealerships and features a starting MSRP of $61,995. These prices include a $1,395 destination freight charge, while the official online configurator for the 2025 model year is live.
