    I took my vehicle to this dealership on February 10th, 2025 for a transmission repair. The repair was made 6 weeks later and cost $2681.27 which was paid and the vehicle picked up on March 17th. My spouse noticed it leaking transmission fluid a few days later, and after I returned home from an out of state work trip, I took the vehicle back to Diamond ***** on April 8th. The service department manager, ****** *******, told us that the original repair was not completed properly and that the repair would be performed free of charge. Since then, there has been no correspondence or communication about the status of the repair, no documentation has been provided describing the work being done, and I am unclear if or when I can expect to get my vehicle back. I have opened complaints with ***** Customer Care and the ***************************************I am seeking a full refund, due to the vehicle not being repaired correctly initially, lack of communication about the repair, and time lost trying to ascertain what is happening with my personal property. I know this may not be possible, however, I feel it is not right to have been charged for such an expensive repair, that they admitted was not done correctly.

    The vehicle originally had a turbine shaft seal leaking, and it was recommended to reseal the transmission assembly. These items WERE performed, and the customer has paid for those repairs. Unfortunately, there were additional repairs needed that we have taken responsibility for and offered to have them repaired. During this repair, we had to open up the transmission again in order to verify that there wasn't more to be repaired, there was even a *************************** communicated with on behave of our technicians with **************, in order to make sure that we were following proper guidelines. Parts had to be ordered and unfortunately some of these parts took longer than expected to come in. Also, this type of repair is not a repair that can be done quickly or even worked on daily due to the number of moving parts that need to align for the repair to be finalized. We had no updates to give the customer during this process and had an employee change during this ticket being opened which may have caused some communication mishaps. All that being said, we have performed the repair, and the customer is scheduled to pick up the vehicle at no additional charge. We feel we have been fair with the customer by fixing this issue at no additional cost, when had we discovered these issues in the first visit, the customer would have been responsible for much more than the approximately $2700 that they have paid for the repairs.

    After reviewing the response, I refuse to accept the issue as settled. My vehicle is now at a professional, *****-certified mechanic, who has found additional damages to my vehicle. 

    Since Diamond ***** cannot make good on their faulty repairs and now I believe has caused additional damage, I have no choice but to seek civil litigation in the matter.

    I bought my Jeep with diamond Chevrolet and I've been three times for the battery light coming on and every time I take it there they say there's nothing wrong oh it's a bad battery oh it's a loose connection on the battery when everything's brand new and they keep taking my money every time I'm there I bought warranty through diamond Chevrolet and they're just stealing money from me instead of fixing it I've called and talked to supervisors and all they say is the same thing you have to pay for a diagnosis and it's the same issue and it's not getting resolved and I want to get my money back I spent over $400 for them to say there's nothing wrong with my Jeep

    According to our records, the customer came in with a battery concern. On the first visit the customer decided to leave and purchase their own battery, which is completely their right to do so. The second visit the customer was advised that there were some connection issues with the battery and cables, and the customer was charged to repair those items.

    We did not STEAL any money from the customer, but we also don't want the customer to be upset. 

    We are willing to work out a resolution internally with the customer in the form of credits or reimbursements. Please reach out to me and ****** *******, the Service Manager, at ************************************ and *************************************** to set up a time to come in get this matter resolved.

    If you have any question, please contact ****** via phone or email.

    We truly feel awful customer feels like we didn't took care of her, ************** came in here a month after she purchase vehicle with concern on her car,
    which we addressed and gave her a loaner car while we took care of the issues with the vehicle. She came and picked up the vehicle after it was repaired 
    and left happy. she came in a few months  later with other concerns on the vehicle which we told her we would be more than happy to help her with, but there is a process 
    we have to follow with her extended service contract she purchase for them to cover the car rental, and we explain this to her we need to diagnose the car before they would 
    approve it. She would have to pay up front for it and then she would get reimbursed for it. Unfortunately she did not want to move forward with the way we told her it had to be done.
    We will gladly be more than happy to help her if she will let us follow the process.

    I purchased a car from them. Unfortunately I got into a car accident and the car was a total loss. The car had a warranty that I am entitled to be paid. Ive been trying to resolve this but they keep going in circles. They no longer take my calls and when they do they place me on hold and eventually hang up. Its been about 4 months now and they have reached out to me or made any progress regarding this. Very unprofessional.

    I met with ****************************** on February 22, 2024. There is a language barrier so I had one of our associates assist with translation as I do not speak Spanish. I completed the cancellation request form, as attached on that date. I asked our associate to advise the customer that I need proof of total loss and the miles at the time of the loss before I am able to proceed with the cancellation. I provided examples as to what documents will list the miles (i.e. police report or the market evaluation report. etc.) This was explained to her in her native language.  Later that day I received 2 emails with the proof of total loss and confirmation of paid off lien from GM Financial.  None of these documents provided me with the mileage on the vehicle at the time of the loss.  She came in some time later and I did acknowledge receiving what she had sent and again explained to her that I need the miles at the time of the loss which to this day, she still has yet to provide.
    We will reach out to her to get the document needed in order for us to process her cancellation.

    In Dec 2023 I bought a ***** LTZ, 2022. Months after the purchase I started to receive recall notices. One of them was the truck was sold without any seat AC blowers. This was not told to me when I purchased the truck. I took it in and they had to order the parts. There were othe recalls, stero cutting out. Trailer connection and running lights need to be reprogrammed. To this date, they gave the blower parts to someone else and have not returned any phone calls or emails. My truck was sold to me missing parts.

    The problem I had with this dealership is that I dropped my car off on 3/9/23, and it took the several days to diagnose the problem with my car, they totally dismissed what I told them. I was not offered a loaner or a rental. I took my car in because it was leaking inside the front windshield, I also took my car into ****** Chevrolet in December 2021, the brake light was cracked, and the headliner had to be replaced after 2 times from the leak. This was my first time taking my car to this dealership, they didn’t honor the warranty, I was lied to about the defective windshield that they ordered, one specific service advisor (*******), and the so-called Service Manager was disrespectful, Unprofessional, and unapologetic. They could have cared less they I had miss 2 days from work because I was stranded, they also refused to pay for the rental car that I had for 9 days, due to their negligence. I have already contacted legal counsel. It will still be an additional 2 weeks before a new windshield will arrive, and I will have to be inconvenienced once again, and possibly miss work again because they refuse to provide me transportation so I can go to work,

    In regards to her complaint the vehicle is not covered under warranty. Bumper to bumper expired 7-1-2022 .
    Her repair was covered by her  car insurance. A windshield would not be covered for leaking after warranty has expired.

    I was looking to purchase a vehicle which was advertised on the dealer website. I contacted the dealer to find out if the vehicle was still available and negotiate the best price. I received an email stating the vehicle was still available and the best price of $18,498.00 I set up an appointment on 2/11/2023 to purchase the vehicle. When I arrived to purchase the vehicle, the dealer raised the price $27,516.00 I reminded the sales manager that I had received an agreed upon price. He then said the best he could to was $20,126.00 I feel this was deceptive and false advertising.
