These Chevy Crossovers Have The Same AWD Issue - What's GM Doing About It?

Why It Matters

The recurring AWD and coolant‑leak defects threaten GM’s reputation for reliability and could depress resale values across three flagship crossovers. Dealers must manage costly warranty work while GM scrambles for a lasting solution.

Key Takeaways

• GM advises reset of rear drive module for AWD fault
• U3000 Sym 92 code indicates unresolved AWD software issue
• Coolant‑leak bulletin covers up to five years or 60,000 miles
• Owners must claim reimbursement by April 30 2027
• Stop‑sale on 2026 Traverse infotainment was quickly resolved

Pulse Analysis

General Motors’ latest service bulletins reveal a systemic all‑wheel‑drive malfunction across its three midsize crossover lines—Chevrolet Traverse, GMC Acadia and Buick Enclave. Drivers of 2024‑2026 Traverses and Acadias, as well as 2025‑2026 Enclaves, report warning messages and loss of traction control, flagged by the U3000 Sym 92 error code. GM’s engineering team has not yet produced a permanent software patch; instead, dealers are instructed to perform a diagnostic reset that restores AWD functionality for roughly thirty minutes. While the fix is temporary, it underscores a broader quality‑control challenge as multiple model years are implicated.

Compounding the AWD glitch, an April 2026 bulletin disclosed a radiator‑hose connector coolant leak affecting the same vehicle generations. GM has extended special warranty coverage—up to five years or 60,000 miles, whichever comes first—and will replace faulty components at no charge. Owners who have already incurred repair costs can seek reimbursement by April 30 2027, provided they submit proper documentation. This dual‑issue scenario forces dealers to allocate additional labor hours and parts inventory, potentially inflating warranty expenses and eroding dealer‑customer goodwill.

Looking ahead, the absence of a definitive software remedy leaves consumers wary, especially as resale markets weigh the risk of recurring faults. Industry analysts expect GM to prioritize a permanent fix to protect brand equity and avoid regulatory scrutiny. In the interim, affected owners should monitor dealer communications, schedule the quick reset service promptly, and retain all repair records for possible reimbursement. The situation serves as a reminder that even established manufacturers must maintain rigorous testing pipelines to safeguard both performance and consumer confidence.
