Chevy Equinox EV Electric Drive Transmission Module Issue: Legal Rights for California Owners
If you own a 2024 or 2025 Chevy Equinox EV—particularly an AWD model—you may be eligible for significant service under GM’s Customer Satisfaction Program (CSP N252502890) addressing a potentially serious manufacturing defect in the front electric drive (transmission) module
What’s the Problem?
GM has identified that some units feature an internal differential nut inside the front electric drive transmission module that is either cross-threaded or missing altogether. This condition can lead to drive instability and even full module failure.
To address this, GM is instructing service centers to replace the entire front electric drive module, along with related components such as A/C seals, mounting bolts, transmission fluid, and high-voltage coolant. The repair solution will be covered by GM through August 31, 2027.
Scope and Timeline
Applies to select 2024–2025 Chevrolet Equinox EV units.
GM dealerships must inspect each affected vehicle, then replace the module if it hasn’t already been done—even for new, used, certified, or courtesy units
GM will notify impacted owners via letter or in-app message, and urge owners to schedule repairs promptly
What Owners Are Saying
On Reddit’s r/EquinoxEv:
“The fix involves replacing the entire front electric drive module … transmission fluid, and high‑voltage coolant.”
— User report summarizing the required repair
Another user noted:
“If you bought it AFTER 7/16/25 then your car is definitely not affected.”
— Suggesting production date thresholds for impacted vehicles
Technical Background
The Equinox EV is built on GM’s Ultium Drive system, which integrates the motor, reduction gear, and power electronics into a unit called the Ultium Drive module. A defect in this critical assembly—especially a missing or damaged differential nut—can cause performance disruptions or failure of the vehicle’s front-drive system.
Why Recall-Like Fixes Can Trigger Lemon Law Rights
Even with a free repair program in place:
If symptoms remain after module replacement.
If repairs recur more than once for the same defect.
If your vehicle loses significant time out of service.
…you may qualify under California's Song‑Beverly Consumer Warranty Act (California Lemon Law) for repurchase, replacement, or cash compensation—even with a free GM fix being offered.
