I took my 2021 GMC Canyon 2.8L diesel truck with 48k miles on it into Robertsons Automotive on…read moreMonday, 8/5/24. I spoke with Zach who told me they could run a complete diesel diagnosis on the truck for $370. I agreec and they proceeded to perform the diagnostic review of my vehicle. Zach contacted me and said that the diagnosis warranted replacing the fuel rail on the vehicle for which he quoted a price of approximately $2300 to do so. Trusting his diagnosis and agreeing to spend the money to repair the vehicle, I agreed to the repair. However, after replacing the fuel rail, Zach proceeds to tell me that the diagnostics were faulty due to no fault of Robertsons automotive but rather due to the fault of GMC not providing better information for them to use during diagnosis. Zach told me that I was going to have to pay for the fuel rail even though the vehicle did not need a new fuel rail. Zach also said they were going to move on and go to the next step the diagnostics said the vehicle needed which was a high-pressure fuel pump. When I questioned Zach about the cost involved for replacing the fuel rail and told him I could not pay for that if it was not what was required to fix the vehicle, he then said that he would see what he could do "to help me out " financially. Zach next told me that he was going to make a decision in his manager's absence to credit the labor charges for installing the inecessary fuel rail leaving me owing Robertsons appx $1100. I then got online and started looking at the GMC 5yr/60k mile powertrain warranty which specifically said it covered the fuel pump. I them spoke to Zach and informed him of this warranty information and he acted like he knew nothing about it and said that I should verify it with GMC by calling the dealership and giving them the Vin number and the mileage on the vehicle. I called Hall GMC Buick on the Loop in Tyler, Texas who verified that the fuel pump would be covered under the powertrain warranty. If I had not found the warranty information and brought it up to Zach, I am 100% confident that Zach would have gone ahead and sold me a repair for a high-pressure fuel pump for the amount of appx $4000. I ended up paying Robertsons automotive the $370 for the faulty/incorrect diagnostics and another $700 or so for the fuel rail that the vehicle did not need. I subsequently was told by Hall GMC Buick that the fuel rail Robertsons has unnecessarily replaced was ALSO covered under the GMC powertrain warranty. I then made Zach aware of this fact and asked him to refund the $700 paid for the fuel rail. I was told by Zach that he took my request to the owner and was told that "they had eaten the labor charges on it and that was the best they could do for me." I also asked that the truck be checked for excessive road noise while they had it. I was told that they checked it and that it was just the road noise from the type of tires that were on there. Upon getting the truck to GMC Buick, my truck was found to be severely out of alignment and the tires had worn unevenly and we're causing extremely loud road noise in the cab while under operation. GMC Buick aligned the front end and replaced all four tires and the truck now drives better than it did when I first got it. This should've been a no-brainer diagnosis for Robertsons who was so hungry for my money that they charged me for something I didn't need and when they could've aligned the front end and sold me four new tires. Go figure! I paid Hall GMC Buick a $120 diagnostic fee, which was later applied to the actual repair that was under warranty. Hall GMC Buick diagnosed the problem as a faulty fuel sensor located on the engine. The problem was not the $4000 high-pressure fuel pump that Robertsons Automotive tried to sell me. I am seeking a complete refund from Robertsons Automotive that I paid for an incorrect diagnosis and a high dollar part that was not needed. Very very unethical and inept business practices by Robertsons to say the least. CONSUMERS BEWARE !!!
