I am writing to express my deep dissatisfaction with the way GMC has handled the recent incident involving my 2021 Yukon XL. As a loyal customer and owner of multiple GMC vehicles, I am highly disappointed with the lack of empathy, ineffective solutions, and unprofessional behavior exhibited by the representatives at Rice Buick in Knoxville and the policy and procedures of GMC customer service issues.

On September 21, 2023, at around 9 am, my 2021 Yukon XL abruptly stopped functioning while I was driving, leaving me stranded in the middle of the road. This incident occurred despite the vehicle having only 23,800 miles on it. The fact that my vehicle suddenly died and couldn't be put into forced neutral due to its button-operated system created a hazardous and stressful situation for me.

When I contacted a dealer for assistance on how to safely move the vehicle out of the road, I was shocked and appalled by the proposed solution by Tim, the service tech at a dealer in Marietta, GA. The dealership suggested pouring Dawn dish detergent on the tires and dragging my 90K vehicle onto a flatbed tow truck. This suggestion was not only impractical but also disrespectful to the value and quality of my vehicle. As a customer, I expected a more professional and suitable solution to the problem.

After a painstaking wait of 36 hours, my vehicle was finally picked up and taken to Rice Buick in Knoxville. I was informed that the fuel pump was broken and that there was no estimated timeline for when it could be repaired due to the part being on backorder. Moreover, I was shocked to find out that I had to request a loaner vehicle as it was not offered to me initially. This lack of consideration for my inconvenience only added to my frustration.

Furthermore, the process of obtaining a loaner vehicle has been nothing short of a nightmare. When I called to confirm the arrangements, I was informed that I was only entitled to a loaner vehicle worth $38 per day, which I found to be completely inadequate. I expressed my dissatisfaction to Mark, the manager, who not only displayed a complete lack of customer service skills but was also confrontational and dismissive.

I escalated my concerns to your customer service department and spoke with Pam, who was delightful and willing to assist. However, the response time and lack of urgency in resolving this matter is concerning.

Despite Pam's assistance, I was dismayed to learn that opening a ticket for my complaint would potentially take up to 72 hours for a response from the manager, Mark. Considering that I am currently without a vehicle and have taken time off work to handle this situation, waiting for days to receive a resolution is simply unacceptable. We all know Mark said he was not willing to do anything more than the $38 a day so why are we wasting time?

To make matters worse, I later discovered that I was speaking to the Canadian representative instead of the appropriate department. It is extremely frustrating that this error was not clarified by Pam during our conversation. However, Diana, the representative I spoke with afterwards, was professional and understanding. She escalated my complaint to her supervisor, who, I was informed, would respond within 24-48 hours. Again, this timeline is simply unacceptable given the circumstances.

I want to emphasize that as a loyal GMC customer, I have taken the necessary precautions by purchasing various warranty packages to the tune of over $8,000, including the Prepaid Maintenance warranty, Total Loss Protection, Mechanical Failure Service Contract, Protection Membership Plan, and Paint and Defense Warranty. It is disheartening to be met with resistance when requesting a fair loaner vehicle, considering that my vehicle is still under warranty and the issue was not caused by any fault of my own.

I firmly believe that GMC has a responsibility to provide appropriate customer service and support during situations like mine, where a major component of my vehicle has failed and a necessary part is on backorder. I should not be burdened with the consequences of GMC's design flaw and the resulting inconvenience and financial strain.

Therefore, I urge GMC to take immediate action to rectify this situation. It is essential that I am provided with a comparable loaner vehicle without any additional cost, in accordance with the level of my vehicle and the warranty coverage I have invested in. This is a reasonable expectation, and it is the responsibility of GMC to fulfill their commitment to customer satisfaction.

Moreover, I strongly request that GMC reevaluate and improve their customer service procedures. The lack of communication, dismissive attitude, and excessive response times exhibited by Rice Buick in Knoxville and the ridiculous procedures by GMC, demonstrate a disregard for customer satisfaction and they do not uphold the high standards associated with the GMC brand. GMC must hold its dealerships accountable for providing exceptional service and resolving customer issues promptly and efficiently.

I trust that GMC will take swift action to address my concerns and provide a satisfactory resolution. As a loyal customer, I deserve prompt and appropriate assistance to rectify the unfortunate situation I have experienced. I sincerely hope that this incident will serve as an opportunity for GMC to review and enhance their customer service protocols, ensuring that no other customer has to endure the frustration and inconvenience that I have faced.

I kindly request a timely response to this complaint, addressing my concerns and providing a satisfactory resolution. I expect GMC to honor its commitment to customer satisfaction and take the necessary steps to rectify the issues I have outlined. Additionally, I anticipate a comprehensive review of the dealership's customer service practices to prevent similar incidents from occurring in the future.

I value the GMC brand and have been a loyal customer for years. I sincerely hope that GMC will restore my faith in its commitment to exceptional customer service. I look forward to a prompt resolution to this matter.

Thank you for your attention to this letter of complaint. As a concerned and dissatisfied customer, I am committed to pursuing resolution for the issues I have outlined. I will make use of available channels, such as sharing my experiences on social media platforms and filing complaints with relevant consumer advocacy organizations, to ensure that my concerns are heard. I trust that GMC will take decisive action to address my grievances and work towards a satisfactory resolution.

I've waited over 2 years for the refreshed sierra hd to be in production. It was pushed back multiple times due to the chip and other shortages. I finally got to order one in May. I waited for over 2 months for it to ship. Now it arrives damaged, and the dealer did an awful job touching it up instead of sending it to a body shop like told me. They won't budge on price, and say that another buyer won't care about the scratch and will pay msrp. Is it possible to reorder and move my build up ? Or do I have to wait 3-5 months again? I think you need to find more reputable shipping companies or allow me to pick up my truck myself.

I am not reviewing a vehicle I have bought. I have been interested in buying a Chevy trailblazer for two years. My excitement to finally order my red Chevy trailblazer, it was such an exciting day. I knew I had months of anticipation. Five months after ordering it, I was informed that GMC is not painting Chevy trailblazer is red, in fact, they are a Crimson color. The disappointment in hearing this brought me to tears. I have been looking at the picture of my red trailblazer for five months, I've been showing it to everyone that this is the car. I'm going to get, for five months, and now I am still waiting on my car to come in, but in the wrong color. How on earth can you advertise over and over, on your website, on TV ads! I just saw the Chevrolet commercial with four very red vehicles.!!!!
I really would like an answer to this

Your commercial for your 2022 GMC line up are very disappointing. Your commercial showing people clapping to the music or passing other cars completely hands free is very irresponsible in todays marketplace. As it is, drivers seem to be unable to drive without one hand clutching their cell phones and actually using it while driving. The fact that you're commercial actually shows people distracted and driving the truck completely hands free is really very irresponsible and completely sending out the wrong message to the driving public. As a commercial truck driver with thousands of miles on the road every week I see the the lack of seriousness and attention that current drivers pay while behind the wheel. You're advertisement agency is doing a great disservice to the GMC brand.

Concerning a 2016 GMC Acadia SLT

In less than three years, this vehicle has required an unusual number of atypical repairs. Most recently, the steering failed. Previous unresolved complaints include persistent Infotainment System crashes and extreme/aberrant vibration and undercarriage noice when ascending steep hills. Previously owned a Yukon Denali Hybrid. Established service at local dealership Thorson of Pasadena. On average every three months both previous and current vehicle received oil change service at Thorson. Additionally, any other major service performed at Thorson. So six year relationship with Thorson. For two years (while in warranty), we informed Thorson of the Infotainment crashes and the issue encountered when Acadia ascends steep hills. Each time, for two years, we were told "no issue" discovered. Three weeks ago the steering fails. We bring the vehicle into Thorson for evaluation and repair. Told steering pump and hoses failed. $1200 repair required. Car out of warranty. We contact Corporate Customer Experience regarding why the steering on a relatively new car would fail. Long story short, GMC agrees to cover half the cost of repairs. We still question WHY steering would fail on a less than 3 yo vehicle. We mention the persistent issues we have had with vibration/noise when ascending up hill and ask whether the steering issue could be related. We auth repairs. Since Thorson did not offer a loaner we rent a car. Three days later the vehicle is repaired...or so we think. We pick the car up in the evening and head immediately to an out of town commitment. On the freeway going 65 mph the steering fails!!!! We are 30 miles from home with our kids in the car. Next morn we call Thorson. THEY WANT TO CHARGE US TO DIAGNOSE WHAT IS WRONG WITH THE CAR!!!!!! We say heck no!!!! We left the car at Thorson, got another rental (again no loaner was offered). After TWO DAYS a manager agrees to do an assessment of the vehicle and discovers that THE REPAIR THAT THEY DID WAS IMPROPER AND THAT THE PUMP THEY INSTALLED LEAKED FLUID AND CONTAMINATED THE ENTIRE STEERING SYSTEM. As a result the entire system would have to be replaced. They agree to cover the cost of the repair (and act like they are doing us a favor). WE CALL GMC CORPORATE CUSTOMER EXPERIENCE AND REPORT WHAT IS HAPPENING. They concede if we were not offered a loaner a rental car credit should have been offered. In light of the repair history they also began the process of weighing a vehicle buyback option. WE INSIST TO CUSTOMER EXPERIENCE THAT THORSON BE HELD ACCOUNTABLE DUE TO THEIR PAST NEGLIGENCE TO ADDRESS OUR PERSISTENT (TWO YEAR) COMPLAINTS ABOUT THE INFOTAINMENT CRASHES AND THE EXTREME VIBRATION/NOISE UPON ASCENDING STEEP HILLS. Customer Experience agreed to intervene. Very long story short...THORSON REFUSED TO ADDRESS THE ISSUES RELATED TO THE INFOTAINMENT SYSTEM OR VIBRATION/NOISE. They indicated that they would only address if we pay for diagnostic and repairs. We argued that when the car was IN WARRANTY WE DID PERSISTENTLY COMPLAIN AND THEY FOR TWO YEARS SAID THERE WAS NO ISSUE. As recent as April 1, 2019 we had brought the car in for service and mentioned the issues again and was told "no issue." Last week they finally suggested it was "likely" the bushings that were causing the vibration/noise issues. How they made that assessment we do not know. They said it would cost us $1200 to repair. We said they should eat the costs. OUR ARGUMENT IS THAT THEY WERE NEGLIGENT WHEN THEY FAILED TO PROPERLY IDENTIFY THE ISSUE WHEN THE VEHICLE WAS IN WARRANTY. As importantly, why were the bushings failing on a vehicle that was one year old (when the problem began). BTW...the vehicle has never been in an accident. WE COMPLAINED TO CUSTOMER EXPERIENCE WE FELT THIS POSITIONING BY THORSON WAS UNREASONABLE. BTW...while all this back and forth is going on, they still have our vehicle and we are still paying for a rental. Communication with Customer Experience was poor and ineffectual. They are IMPOTENT. Two days ago, 3 weeks into this debacle, I call to follow up since we were getting no where with the dealer or Customer Experience. The once pleasant Experience Rep is now bordering on rude/dismissive (someone must have gotten their hand slapped for playing nice with the customer). She informs me that our vehicle repairs are complete, in a nutshell Thorson refuses to address the Infotainment and vibration/noise issues, and Thorson will not reimburse any of our rental car costs. Further if we do not pick up our vehicle IMMEDIATELY they will SELL OUR VEHICLE!!! Yesterday we picked up our vehicle. Surprise surprise...the steering is still faulty. We immediately emailed Customer Experience an update to include a video of the vehicle experiencing the vibration/noise when ascending a steep hill. BTW, it bears mentioning THORSON LIED AND TOLD CUSTOMER EXPERIENCE THERE WERE NO SERVICE RECORDS INDICATING THAT WE EVER COMPLAINED ABOUT THE INFOTAINMENT OR VIBRATION/NOISE ISSUES. We keep EVERY SERVICE RECORD EVERY PROVIDED and sent the Customer Service Rep the records from the past five months. The records clearly state our complaints about the noise/vibration. WE HAVE RECEIVED NO FURTHER COMMUNICATION FROM CUSTOMER EXPERIENCE. IT IS CLEAR GMC DOES NOT STAND BEHIND ITS PRODUCTS NOR DOES IT VALUE ITS CUSTOMERS. We have a lemon and now have no choice but to pursue legal action against THORSON and GMC.
