Two Months of Finance and Paperwork Failure – Deal Still
Two Months of Finance and Paperwork Failure – Deal Still Not Fixed On September 22, 2025, I purchased a used 2025 GMC Sierra with ~17,000 miles from Chuck Nash Chevrolet Buick GMC. I traded in two vehicles: -2022 GMC Sierra – financed with GM Financial -2022 Buick Encore – financed with Chase Auto Finance The next day, September 23, I discovered the odometer mileage on the 2025 Sierra did NOT match the contract. The truck actually had nearly 24,000 miles—almost a 7,000-mile discrepancy. I notified the dealership immediately. On September 27, I met with the used car sales manager. He refused to offer anything in writing and verbally offered only free fuel and oil changes for 7k miles. When I asked for that in writing, he told me: -“I won’t be held hostage over the mileage error.” -“Take the verbal deal or we’ll cancel the deal.” I asked for until the next day to decide. On September 28, I cancelled the deal and returned the 2025 Sierra. The dealership returned both of my trade-in vehicles. That should have been the end of it. It wasn’t. As of November 14, 2025 — almost TWO MONTHS later: 1️⃣ 2022 GMC Sierra loan (GM Financial) — STILL not reinstated GM Financial shows: -$0 balance -“Payments Unavailable” They repeatedly tell me they are still waiting on Chuck Nash to submit the unwind paperwork. 2️⃣ 2025 GMC Sierra loan (Greater Texas Credit Union) — STILL ACTIVE & LATE Even though I returned the truck on September 28, the credit union shows: -Active loan -Payment due Nov 6, 2025 -Loan now marked late I am being charged for a truck I do not have. 3️⃣ 2022 Buick Encore loan — delayed so long, it showed months of late charges I finally sold the Buick myself to Mercedes-Benz of Austin, but that transaction is still not fully completed, and I am still waiting on final resolution. Loyal customer for 20+ years — treated like this? I’ve bought over 10 vehicles from Chuck Nash in the last two decades. This is only the second issue I’ve ever had with them — but it is by far the worst. I truly don’t believe the dealership appreciates long-term loyal customers. If this is how Chuck Nash treats loyal customers, then it may be time for me to go elsewhere. Shame on you, Chuck Nash. Shame on you. Buyers beware.
