Our Reviews
This is an update to my September 7th review on my 2023 Buick Encore GX. I hope Mr Nash really reads these review and genuinely care about his customers because I feel like his service dept. doesn't. Like I stated i took my car in for warranty work and they told me it wasn't the turbo but the turbo cooling hose. I was charged $898.00 for the repair which was about all I had left in the bank as i live on SSI and I had just paid my rent leaving me broke. I supplement my income by driving for Uber and Lyft but because my car has been in the shop since August 31st and unable to work as this is my work vehicle,I've exhausted all my funds . Long story short I spoke to Mr. Lopez about the problem and how the misdiagnosed it. I also did research on the probable cause for the cooling hose to fail and in speaking to other dealer technicians and also through Google I found that the blown hose can be caused by a failed turbo as the engine will run at higher RPM's than normal putting excessive pressure on that hose. I explained this to Mr. Lopez as this would fall under warranty repair associated damage and he told me he would check into it. On Tuesday the 8th I went back to speak to Mr. Lopez only to be told that there would be no reimbursement of my charges because the technician said the blown hose caused the tubo to fail. So they basically turned it around on me in order to not be out of money for the repair. I feel unappreciated as a valued return customer of Chuck Nash. I have been a return customer since 2017 and this is my third Buick I have bought from them. I tried going over to the dealership to speak to the GM about the situation only to be told the service dept doesn't have a GM. Mr. Nash I know your a successful business man and you give a lot back to the community and i applaud you for that but I'm just a 70 year old man trying to make ends meet and $898.00 may not be much to you but to a retiree struggling to survive in today's economy that amount was all I had to help meet my obligations which now I can't. If you really care about your customers then I hope to hear back from you on this unless all those review replies from Chuck Nash with (owner) next to them are AI generated responses. I feel taken advantage of and if we can't resolve this amicably then I'll take my future business elsewhere.
I took my 2023 Buick Encore GX in for warranty repair on a failed turbocharger. I told my service writer I had gotten it diagnose and it coded out to be a failed turbo. The technician then diagnosed it and said it was a blown turbo cooling hose. I was charged $898.00 for the repair only to drive off the lot 2 miles and the engine light came back on and the instrument board message saying engine reduced power which is why I took it in for in the first place. The service agent (Seneca Coats) had charged me for a new hose because he claimed it was not a turbo warranty related issue. I spoke to the service manager (Robert Lopez) and explained the situation seeing my car had been there 5 days and they couldn't get to it for another 4 days which to me was unacceptable. He assured me they would get on it right away. Come to find out the turbo was bad all along and after doing some research come to find out that the blown hose could have been cause due to the failed turbo creating excessive pressure due to the higher running RPM'swhich would classify the blown hose as warranty related damage and i shouldn't have been charged for the repair. I feel they misdiagnosed the problem as I had already told my service writer that the turbo was bad. I feel I'm owed a refund as it was a warranty related issue. I have been a loyal customer of Chuck Nash since 2017 and a return customer as this is my second Buick I have bought from them. I take all my service needs and repairs to them as they have always done good in the past. I will reach out to Mr. Lopez on Tuesday when they come back to work and if he can't resolve the problem then I'll go up the ladder to the general manager and so on until I get some positive results on this matter. Im 70 years old on a fixed income and that $898.00 charge left me broke for the rest of the month!
⭐⭐⭐⭐⭐ Absolutely outstanding service from Megan Moore! I brought my 2021 Chevy Blazer in for service, and Megan Moore was absolutely amazing from start to finish. She handled everything professionally and went above and beyond to get my repairs 100% covered under my warranty, which I truly appreciated. What really stood out to me was how transparent, informative, and detailed Megan was throughout the entire process. She took the time to explain what was happening, kept me informed, answered my questions, and made sure I understood everything before moving forward. I never felt confused, pressured, or left wondering what was going on. Warranty-related repairs can be incredibly frustrating, but Megan made the entire experience FRUSTRATION-FREE! She genuinely cared about helping me and made sure everything was handled correctly. I have dealt with automotive service departments before, and I can honestly say that Megan provided the best service I have ever experienced when it comes to warranty-related work. She is a true asset to the service department and deserves recognition for the way she takes care of her customers. Thank you, Megan, for making the whole process so easy and stress-free! 5 stars all the way! ⭐⭐⭐⭐⭐
They did a great job after I got rear-end. My Broco looks like new. I would recommend Chris and his team to anyone. Chris kept me informed throughout the process.
I have to say that I have never met a nicer and more kind bunch of people. They were personable and professional and oh so very helpful. I highly recommend. Thank you, Maria and Chris.
Very good service. Kept us well informed. Liz went above and beyond working with the insurance company to get our truck repaired and back to us quickly.
Great customer service, Maria especially was very sweet and helpful! They even offered to give me a ride home during my alignment so that I didn’t have to wait, which I didn’t end up needing because they got it done quicker than expected, but I thought was super nice.
I brought my car in to get some repairs done. They were so easy to work with. Even contacted Enterprise and set me up with a rental. They kept me updated through the time my car was repaired. It looks brand new. I'm really impressed with them.
My vehicle was in for collision damage. Repairs were completed and phenomenal.
Chris Narveiz was very professional and very good to work with. Thanks again Chris
Great service and communication
I purchased a new 2026 Nissan kicks that had a passenger door that would not close right cavender Nissan sent me here at chuck Nash to correct Nissans flaws.
I had some service work done after my AC died on me in our Texas heat, and delt with Megan who was absolutely AMAZING in service, from start to finish. I can't tell you the frustration I had when I purchased my extended warranty from Bluebonnet, and had to call the war company only to hear nothing but negatives from them. I took my vehicle to Megan at Chuck Nash, and explained the situation, and she said "I got you!" and I believed her. She kept in contact with me 100%, and let me know everything they were doing, and what they were waiting on. She NEVER over promised anything, and was straight out of the gate. can't say enough about the service, and professionalism from Megan, and everyone I ran into in that dealership, and service dept. I'm not one to write reviews much, and just let things go because of all of the intitled Karen and Bob's of the world who except everything for nothing. I'm not that guy. I genuinely appreciate her, and the service department she represents. Art Garcia
