Maximum Diesels

"We took our truck in because the light came on and our gas gauge stopped working. They said it was a bad sending unit so we had them replace it. We left a few days later after picking up our truck to Az. We stopped at Sams Club Bullhead and filled up the tanks before we checked in to our hotel.. When we came back to the truck a few hours later we found that the fuel had been leaking onto their parking lot (so much that security and the fire dept had been called and were there). Of course being on a weekend we had to wait two days to be able to get someone to fix it. Meanwhile we had no truck and had to extend our stay there not to mention the gas lost. The seal on the tank had not been installed properly causing the leak.. The did reimburse us the cost of the repair but only that.. A couple months later we had to bring it to them again because the light came on again.. They said it was a faulty sending unit again and replaced it but did charge us a diagnostic fee which we feel should never had been charged since it was the same issue. Well again short while later the light came on again so this time to try and avoid another diagnostic fee we stopped at Autozone to plug their little diagnostic tool and it said again something wrong with the sending unit so we brought the truck back to them. Needless to say they were not happy and would not fix it and said it was because we were overfilling the auxiliary tank but we have a gravity fill tank so that is not possible. (Note we have had our truck for years and know how to fill the tanks.). Only if we had an electric pump could that happen and we do not.. When the mechanic brought the truck out to us we asked him about it and he told us it was never looked at this time so couldnt say why this was happening. We then immediately took it to another mechanic and they fixed it. We informed the Bureau of Automotive and they investigated and found they were at fault and that besides that the new mechanic said the seal again was not installed properly even though it had not started leaking yet and the Bureau's agent informed them that the reason saying we were overfilling the tank was false and suggested that they return all monies involved but they refused.. The owner has been informed we will be going to court on this. Hope he knows that he must tell the truth or it is perjury and we have all documents in place. Whatever you do dont go to Maximum Diesels if you want honesty."

"I had my 01 Dodge Ram worked on. They came highly recommended. Rick and Joe were extremely helpful and kept me updated throughout the process. The truck runs great and I'm extremely satisfied with this shop!!! I plan on bringing the truck back in the future. Jimmie"

"Was recommended this shop to work on my 88’ diesel van and wish I never listened. Poor communication for the first visit, got my van back and the problem I sent it in for was still occurring. Sent the van back, there was better communication and when I got the vehicle back I discovered it still had the same issues that weren’t resolved. Management was apologetic and said they’d get me compensated then I was ghosted and never heard back. Have tried to email and call with no answer. Do NOT take your truck here."

"The guys at Maximum Diesels are the best. Russ is very knowledgeable and extremely honest. My truck has been maintained by the guys for over 15 years. They do everything for routine maintenance to extend builds. Give them a shut if you have a diesel."

"This shop had our truck for months. We’ve spent thousands of dollars and beyond that, we invested and gave our trust. Shop Manager has weak customer service skills and less than average etiquette. We asked for two things: to fix our truck and to communicate. This shop could barely do one let alone both. Owner/Manager were caught in several lies regarding call backs, ordering parts, etc. When confronting them to dispute these basic needs as a customer, they did a great job at trying to gaslight us in making us feel as we were the issue. Will gladly pay a bit more elsewhere if it means peace of mind, human decency & a fixed truck. 0/10. Two thumbs down."
