GMC Acadia to Diamond Buick GMC Palmdale previously known as Rally, I brought it in because it was having hard shifting and when accelerating, it would sputter and go into reduced power previously known as Rally, I brought it in because it was having hard shifting and when accelerating, it would sputter and go into reduced power mode where it would almost come to a rolling stop . Prior to bringing it to the dealer I had done everything to the best of my ability to fix the P0420 code along with the hard shifting, sputtering, and the reduced power mode with no resolution. I was tired of throwing good money after bad. I am a hard working single mother, so I had decided to take my car to the dealership I thought they would be able to put an end to all my troubles as this is their area of expertise and I would be able to move forward with a problem free, dependable vehicle. Well to my dismay my problems with this dealership were just beginning, costing me more than I ever imagined, and a long road of high expectations, promises and ultimate disappointments . The service technician Ivan advised me that I had a misfire on cylinder #1 and that my cat needed to be replace but prior to bringing the car to the dealer I took it to D&D muffler, they did a compression check and stated that my cats had no clogs it had a cat code which was P0420 and it could be several different things causing that cat code to go off, but the dealership Ivan said I needed to replace the coil pack and spark plug on cylinder #1 and stated that my car would be fixed except for the cat code which would not affect the way my vehicle would drive. OK great, I paid for the repairs and was on my way . Well to my disappointment I didn’t even make it home before my car was doing the same thing if not worse than before. Keep in mind they had it from April 22-27, 2022. They would not provide me a rental, therefore, I was left with no car, no means of transportation, to get around and do the necessities or things with my 6 year old. I had come here for a summer visit and was unable to do anything for the summer with my son, for the exception of watching the paint dry on the walls. Ivan told me to bring it back and they would take another look at it, so May 5,2022 I brought my car back to Diamond GMC . Ivan called with an update and notified me that my tork converter and fuel pump needed to be replaced expensive parts to replace especially in my situation as a single mom visiting for the summer from Idaho. So I double checked with Ivan, are you sure this is going to fix it because I can’t just be throwing money into it hoping for resolution. He confirmed that it would besides the P0420 code which again would not affect the way the car drove so I confirmed the replacement and I was going to look into getting the tork converter replaced in a couple weeks . So after that replacement a couple weeks go by and my car is still doing the SAME thing. I looked into getting it done elsewhere since I no longer trusted Diamond's work ethic, honesty, or work to be done right. but they had said something along the lines of it having to go through the dealership. So I bring my car into Diamond again to have the tork converter replaced, I get a different service provider Robin by this time she contacted my extended warranty company they said someone would come out to confirm that the tork converter needed to be replaced within 24 to 48 hours 4 days go by, maybe more ( keeping in mind that I had no vehicle or means of transportation) so I obtained a rental car (out of pocket) no consideration from Diamond to provide anything (which they could have as a gesture of goodwill) for my son and I knowing full well our situation. The gentlemen that came out from my warranty company said that the cat needed to be replaced first before considering replacing the tork so mind you I’ve had a rental this whole time when I dropped car off with Robin coming out of pocket because warranty company hasn’t approved the claim so I order a new cat cost came out of pocket again so another week goes by with my car just sitting at the dealer with nothing being done to it I was advised that if I picked up my car until cat had arrived I would lose my place inline for the repair and I would be on the waiting list for 3 weeks so left it there I asked if I could put the cat on myself so I didn't have to come out of pocket for the labor they said no, got the cat and they put it on then contacted warranty company again had to wait another 24 to 48 hours to have another person come out to confirm the repair they finally approved the claim they said they would reimburse me cost for rental for 2 days while they put the tork converter on by that time I had no money left for a rental.

Phillip Salas, was the service advisor on my first servicing at this dealership, we took my car 2019 Cadillac CTS in for a problem we were experiencing, they promised us they would contact us when car servicing at this dealership, we took my car 2019 Cadillac CTS in for a problem we were experiencing, they promised us they would contact us when car is ready that day, but however they did not call, so we called and spoke to Phillip, he told us that they were unsuccessful in finding the problem that we were experiencing with the car, so he suggested that they would need it for another day to check it again, they had it for almost a day, then called us near closing time and said to come and pick up the car as they again said they failed to find the problem, we then came to pick up the car and Phillip told us that the problem could of been the Auto Stop was doing what it was suppose to do, we then told him that it was off as we disabled the auto stop and the car should not be shutting off, we continued to have the stalling for a few more days then it stopped stalling one day on it's own, so problem fixed itself, don't know how or why but happy it did. We recently reluctantly went back to Rally GM Store to have an oil change, new filter and to install a new cabin filter on the car, I was very happy with their work the second time and they did not charge us much, happy with that as well, I guess we will forgive them for the first visit not being satisfactory, but if they fail us next time I will no longer use that Rally GM Store for my servicing needs. On this second visit I will give them five stars for their service in all aspects. More

They didn’t do good, I took my Tahoe for repair, they told me a price and it didn’t fix the problem. They called me and said that the initial price was just a starting point and that it was actually some told me a price and it didn’t fix the problem. They called me and said that the initial price was just a starting point and that it was actually sometime else that needed to be fixed. They were playing the guessing game. More

Horrible parts service and customer relations WARNING!!!!! Horrible parts department service. Had my vehicle break down on the hwy on my way to AZ. Trusted the parts department to get the engine within 7-10 da Horrible parts department service. Had my vehicle break down on the hwy on my way to AZ. Trusted the parts department to get the engine within 7-10 days as promised via the parts counter. Vehicle took over 2 1/2 weeks to make it to the shop after it was ordered. Do not trust what they say and would not cover rental costs but where happy to say sorry we will take 100 off for your troubles. WARNING!!!! DO NOT BELIEVE WHAT YOUR TOLD FROM HERE! Bad service and gave several chances to make it right. I've been around shops all my life and can believe they would treat a customer who spends thousands on a part so horrible... You have been warned..... More

Great service If you want a dealership that has years of experience from technicians to management then Rally is the place to service your vehicle. The other GM dea If you want a dealership that has years of experience from technicians to management then Rally is the place to service your vehicle. The other GM dealership in Antelope Valley is horable in comparison to these guys. Rally has the most knowledgeable people in the business. I brought my car in with a problem that no one could fix and they fixed it in 20 minutes wow great service More
