Dealer response

Well, you did what you promised, Google review. As a Service manager of 23 years, you understand the business and intimidation of reviews. The recall that you mentioned is a TSB for base warranty (3yrs/36K miles), your vehicle has over 100K miles but expect GM to cover anyway, the cost to a guest would be 1.0 hr of labor @225.00 if they accept repair. You the expert understand that GM has extended the warranty on the cooling thermostat housing, only the housing. If any additional issues with wiring, connectors, water pump, etc, there is no coverage through GM (out my mileage/time). We ask for a diagnostic fee to cover the technicians time while we investigate all possible repairs, once found, check for any warranty coverage. Items covered by warranty are no cost to guest, we never were able to investigate. Another shop may be telling you one thing, however once you arrive and all the details are in play, you would receive they same request that was given by our store. Question for you, this first TSB has been out since 2022, you purchased used in 2023 @54K miles, had you gone to a GM store then, more assistance would have been provided. Its a shame you attempt to distort facts with frustration and threats to receive free work.

Consumer response

Took to medved ABSOLUTELY NO ISSUE!! Scanned dignosed and repaired. Costed me 100.00 on second diag reached out to warranty GM!! Approved in 15 minutes. You both lie and cheat customers! Please reframe from your voicemail messages! Don't be a Keyboard Warrior.... I'll just show up and take care of your mouth!! Have a great night!! Stay away from these CROOKS!!

Jose and the gentlemen who ran the numbers were

Jose and the gentlemen who ran the numbers were absolutely amazing. My finance lady was so beyond amazing. They all were great and i had such a better time buying a brand new car then i thought it would be for my first time. Absolutely had an above and beyond type of experience. I'm so thrilled with my purchase and how the process went.

On July 29, 2025, I purchased a 2021 Chevy Suburban from

On July 29, 2025, I purchased a 2021 Chevy Suburban from O'Meara GMC for almost $40,000.00. Upon pickup, I discovered the middle row seat adjustment handles were in the glove box, and the seat would not return upright. Sales and service staff attempted repairs but failed, and the vehicle was kept overnight. I was told parts needed to be ordered and that I would not be financially responsible. I was later informed I couldn't drop off the vehicle for repair until August 7, which I did. I drove my new car with the broken seat until 8/7. During the time my vehicle was being repaired, I was given a loaner vehicle with recurring tire pressure issues, including a flat tire by August 13. It was unsafe to drive. On August 14, I was given an electric loaner vehicle, which was highly inconvenient. Charging took over an hour for only 80 miles of range, causing me to miss work and personal obligations. On August 25, the dealership charger was unavailable when I was assured it would be ready for charging. I picked up my Suburban on August 26 after three calls letting me know if was ready. The seat was repaired, but the plastic cover between the middle seats was not properly closed. It is wide open with grease exposed. I reported this on August 29 and received no response. Additional concerns include a worn tire noted in the inspection that was not replaced until I requested it, and a misrepresented heads-up display feature that my model does not include. I had been without my vehicle for nearly a month immediately after purchase, I was expected to rely on unsafe or inconvenient loaners, and experienced very poor communication. I am requesting immediate resolution of remaining issues, a clear timeline for any further repairs, and confirmation that my vehicle will be restored to full working condition. GMC O'Meara needs to take accountability and compensate me in some way for the hassles I have been experiencing. Steven lied on the BBB response and my seat is still not fixed to 100%. These people are grimy.

Run away as fast as you can from this slimy dealership.

Run away as fast as you can from this slimy dealership. Had a deal negotiated to the penny on a '26 Sierra EV AT4 with one of the managers including my trade-in. This was on a Thursday morning. By late afternoon I became concerned that I hadn't received the written deal via email as promised. The manager was gone so I spoke with the salesman I initially contacted. He told me he would have to speak with the GM to see if they could hold the vehicle. I told him I had a done deal and was ready to give a deposit on my credit card. He wouldn't take my deposit and said he would speak with the GM in the morning. The following morning I was told the GM had agreed to hold the car the following Monday if it didn't sell over the weekend. I told him that's not how I do business and would purchase elsewhere. Monday I receive a text from the Salesman that it didn't sell and was still available. Now way I'll ever do business with such a sleazy dealership. I purchased from a different Denver dealer that treated me like royalty. Wasn't able to work my trade into the deal but I'm confident I'll come out ahead by selling it myself. Plus I got the color I wanted.

Good experience with sales and staff.

Good experience with sales and staff. I drove 2 hours late in the evening from Pueblo West, they had the truck washed and full tank of gas, ready to go.

Absolutely wouldn’t recommend buying a car from this

Absolutely wouldn’t recommend buying a car from this place! Purchased a vehicle on 3/10/25 was told some body damage issues would be fixed if I bought the vehicle. After 2 separate visits and then holding on to the car for 4 days, 1 of which nobody at the dealership knew where my vehicle was, some issues were skipped right over. I’m only giving them 2 stars because the girl in finance and original salesmen I worked with were pretty great. Stephen (some sort of manager) tracked my car down today, got it back to the dealership and then attempted to tell me what the terms of my deal were, when he had nothing to do with the situation until today. Was considering trading my wife’s car in and doing another purchase with them but that definitely won’t happen now. Extremely disappointed with the service here.

Double billed me for a car.

Double billed me for a car. And I paid cash. Yes $23,000 turned into $46,000. Now no one in this company will call me back. I was told he is in charge, and no response. I called corporate office and they said, we will look into it, call back. Now I am forced to go after them legally. And yes the really did this. Be careful who has a paper check with your account number on it.
