Tustin Buick GMC

⭐ 1 Star Review This was one of the most frustrating and disappointing dealership experiences I’ve ever had. They sold me a vehicle with only one key, and the windshield washer system was not working properly from day one. On top of that, they sold me additional warranty and protection plans (tire and battery), presenting them as useful and reliable. In reality, these plans turned out to be practically useless. After the purchase: • I visited the service department twice, and each time I was told that I have no coverage • When I requested cancellation, they became uncooperative and unclear • Now they are refusing to cancel certain plans or avoiding giving a straight answer The customer service is extremely poor. No one takes responsibility, and they keep passing you from one person to another without resolving anything. This feels misleading and very unprofessional. If you are considering this dealership: ⚠️ Double-check everything before signing ⚠️ Do not trust verbal explanations ⚠️ Be very careful with add-on warranties—they may not work as promised Overall, I regret doing business here.

Hello GMC Team, On February 28, 2026, I posted a review regarding my experience at Tustin GMC, specifically concerning the inclusion of add-ons during the purchase process. In my review, I shared that I felt pressured when I was informed that a protection package valued at $4,200 had to be included in order to move forward with the deal. Today, March 1, 2026, I received a call from Tustin GMC management apologizing for the miscommunication. They explained that it was not their intent to pressure me, and that the final price presented actually included an extended warranty rather than a mandatory protection package. I appreciate the clarification and the outreach from management. I accept their apology and want to acknowledge their effort to address the situation and make things right. This type of follow-up and accountability is what excellent customer service is all about. Thank you to the GMC team for taking the time to reach out. Your actions truly go a long way.

False advertising do not shop here, also extremely rude, they posted a truck online for certain price and did not honor it, heading to headquarters next

Tustin GMC I must say this is about the worst experience dealing with a dealership to service a vehicle in my life. I?d like to start off by saying the service advisor (Ruben Regalado) has the most deceptive sales tactics I?ve ever seen. FYI, I?ve been in the mortgage industry for the last 13 years as both a loan officer and in operations. When a customer asks for an itemization of parts and labor it means exactly that. Ruben, decided to first just send a link for me to approve or deny repairs that didn?t have any costs associated to anything. This seems deceptive due to the fact if an unsuspecting customer just clicked on approve for each repair without knowing the costs, they will be held liable for repairs. Second, it took several text messages and emails to finally get an itemization of what the dealership is charging for parts and labor. I do have a third party warranty so that does complicate things but at the end of the day, a customer request is a customer request. I then requested an itemization of what the third party warranty company would and would not cover. Ruben decide to just send an email with the total of what they?re covering and my out of pocket expense. Again, I asked for an itemization. The only reason you wouldn?t want to provide an itemization is to prevent the customer from seeing what you?re charging for parts and labor vs what the warranty is allowing for parts and labor. Keep in mind the warranty company was sending the parts to the dealership. So why exactly are parts showing up on the itemized estimate of repairs? If I didn?t call the warranty company to find this out, I could?ve been charged for parts when they were sent free to the dealership. Beside this, Ruben is unprofessional in the sense stating to me he doesn?t like to communicate via text or email. That I would need to go in to talk to him. No sir, this is the modern day. If you can?t communicate via text or email what are you doing as a customer service advisor? I?m busy with work and two kids. I don?t have time to stop at the dealership just to talk to you. Horrible sales and horrible customer service. Your advisor can?t type nor spell and refuses to communicate via email or text. I?ve been in the mortgage industry for 13 years. I?d run circles around this type of work ethic. Train your people better and make sure they can type!

I hate when i get ripped off or Cheated AND OR FRAUD and this is the case here at Tustin Buick GMC i took my vehicle for an oil change on Saturday the service advisor stated i need front and rear pads the Teck stated they were at 3 mm both front and back that is bad for safety of my family but i didnt get them done there since i had lifetime on the pads This morning i took it to my mecanique as a surprise both of my pads were about 80 % good that is a rip off what thew want to do charge and change parts that are in good condition THAT I SEE IT AS THEM TRYING TO RIP OFF THE CUSTOMERS for non needed parts

Found a truck online they had. Worked a deal with them. Then I have to come to the dealership to sign the papers. I live 2400 miles away. It’s 2026 I don’t understand their upper management policies. Probably the reason it’s rated a 3 stars.

Patrick the general Manager never reached after knowing there was an issue at his dealership . AFIF was an amazing sales guy !

My truck was service and clean in the time promised. The service advisor are allows courtesy and helpful. The dealership and waiting area is clean and easy to assets

Tustin Buick gmc went above and beyond my expectations. Super friendly and helpful staff. They were able to answer all my questions and concerns. I would definitely recomend buying a vehicle from this dealership. Thanks again Tustin Buick gmc for all of your help.

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.
