Tustin Buick GMC

If i could give it 0 stars i would. Horrible experience with trying to sell my car to them. I received an instant offer and they proceeded to not even come remotely close to said offer. I would stay away and. it waste your time if your trying to sell them a car. I got bounced around to 5 different people who were very confused

I do not recommend buying from this dealership. Bought a brand new Buick from salesperson Sheyla. She was pleasant enough. Her manager and the finance guy were problematic. Paid cash. Accepted the Internet price plus a manufacturer rebate. Did not haggle at all. Just wanted the deal to be done and leave with the car. Next day discovered there were 3 hard inquiries made to my credit when I was told it would be a soft id verification and after detailing the vehicle they delivered it with a quarter tank of gas. A subsequent phone call from Sheyla apologizing for the inquiry became a rude rant from her manager, Faizon, after he got on the call. It's amazing how nice they are when they want your business and how unprofessional they can become once the deal is done. Thank God I won't have to deal with their service dept in the future as I'm from out of town. Take your business elsewhere.

⭐ 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
