A Great SUV Undone by a Deeply Troubling Dealership

Reviewed by M SNovember 18, 2025

A Great SUV Undone by a Deeply Troubling Dealership Experience – 2025 Yukon XL AT4 Diesel at Tustin Buick GMC We purchased a 2025 GMC Yukon XL AT4 Diesel from Tustin Buick GMC in October 2025. What should have been a straightforward, exciting upgrade quickly became one of the most disappointing dealership experiences we’ve ever had. 1. Pricing inconsistency before the sale A salesperson initially assured us they could “get us our number.” The next morning, the exact same vehicle appeared on the dealership’s own website for $1,000 less than the price we were offered. We still moved forward because we genuinely liked the vehicle and hoped to build a positive long-term relationship with Tustin GMC. 2. Nearly $17,000 in add-ons presented as a “stretch deal” During signing, the sales manager presented almost $17,000 in add-ons, insisting it was a “really good deal” and implying she had pushed hard on our behalf. We pushed back several times. While they eventually reduced the add-on pricing (not the vehicle price), we still ended up paying roughly double the normal market value for most items — and even purchased redundant coverage based on their assurances. 3. Immediate issue: damaged steering wheel We paid in full and left the same day. Shortly after, we noticed a cut in the leather steering wheel, which we reported immediately. No one provided pre-sale photos or documentation showing the steering wheel’s condition prior to delivery. 4. Communication breakdown when we asked for help When we later reached out regarding both the overpriced add-ons and the steering wheel, no one from sales, finance, customer relations, or management responded. Only when we formally requested to cancel certain add-ons did the finance manager call. During that call, he: • Interrupted repeatedly • Raised his voice • Dismissed our concerns • Told us, “If you don’t appreciate us, you can give the car back.” • Admitted that at least one add-on he sold us was redundant Following this, we requested written communication only due to the tone and unprofessionalism. The only written follow-up we received was a text asking us to mark the survey as “Completely Satisfied” with all 10/10 responses. 5. We still tried to resolve things professionally I spoke again with the customer relations representative, who remembered our case, admitted management had not been informed, and said he would escalate it so someone could reach out. No one ever did. 6. Vehicle issues under 2,000 miles — no response Before hitting 2,000 miles, the Yukon began showing transmission and 4WD system warnings. Again — no outreach, no follow-up, no support. 7. Only after posting our experience did Tustin GMC finally contact us — but only about the steering wheel We finally heard from Tustin GMC weeks later, after explaining our concerns in full. But even then, they only contacted us about the steering wheel, despite the fact that the caller said the customer-relations representative had briefed them on the entire situation. When we followed up in writing and detailed everything again — including stating that if they believe we misjudged the situation, no further communication was necessary — we stopped hearing from them entirely. 8. We also filed an official complaint with GMC Corporate Unfortunately, nothing changed. No follow-up, no accountability, and no attempt to address the larger issues. ⸻ BOTTOM LINE This review isn’t based on one mistake — it’s based on a pattern: • Inconsistent pricing • Add-ons sold far above market value • Redundant coverage sold as “necessary” • A damaged steering wheel immediately after purchase • No pre-sale photos provided • Poor communication • Unprofessional behavior • Pressure to provide perfect survey scores • Early mechanical warnings ignored • No resolution even after engaging repeatedly and filing a corporate complaint The Yukon itself is excellent. But our experience with Tustin Buick GMC was let’s say not great.

My experience at the dealership was excellent from start to finish. Abraham greeted me right away, took the time to understand what I needed, and answered every question with patience and detail. The entire process was fast, smooth, and professional. I truly appreciate his outstanding service and the overall efficiency of the team.
