john leija2025-01-16Trustindex verifies that the original source of the review is Google. Awesome knowledgeable crew that is like family there! Owner is hands on. They tag-teamed a couple issues on my rig to get me outta there in a timely manner. Their work is clean and I trust all them without having to worry about them trying to pull anything shady. Thanks team, keep up the outstanding work! CDW2024-11-26Trustindex verifies that the original source of the review is Google. Just pulled in from out of state with an emergency electrical problem.

Professional Felicia Millen2024-04-11Trustindex verifies that the original source of the review is Google. Nothing more unnerving than getting ready to take a 1,500 mile trip pulling a trailer and our GMC truck is stalling the day before we leave. Called this shop with short notice as we've been here before with another truck & they squeezed us in... What a blessing! Such a wonderful kind crew, they replaced the faulty fuel filter & water drain valve, changed the oil & blew out the very dirty air filter. Even offered our dogs some water. Now we can travel with ease knowing all is good. Diesel Doctors we give you an A++ not only for your work ethics & fun personalities, but also for keeping us safe on the road. AGC Builders Group2024-03-07Trustindex verifies that the original source of the review is Google. First and foremost we found this company on google and went off there reviews , We thought well they seem like they're good but little did we know what was coming. Jesse the owner has repeatedly lied about his work , I ended up taking my truck to another shop after he charged me 5k + and we discovered he used nothing but parts made in Vietnam and used rebuilt parts nothing is OEM. My truck broke down with less than 1000 miles after he worked on it. He tried to charge me and additional 10k + . As a business owner in the Construction industry I would not trust this company. We are now going to take legal actions and sue Jesse for his work and his lies. BEWARE OF THIS COMPANY. Keith Hildreth2023-12-26Trustindex verifies that the original source of the review is Google. Jesse and his mechanics did a great job on my Duramax fuel pump at a reasonable price. Highly recommend the Diesel Dr.for your Diesel repair needs . Ashlan Alexis (ashalexishock22)2023-12-01Trustindex verifies that the original source of the review is Google. Jesse went above and beyond to assist me and found ways to save me money on my repair even when it meant outsourcing a component for my Range Rover. After being jacked around at other repair shops, he found a way to help find a solution and was so professional and accommodating. I’ve never been happier with an experience getting my car fixed which can often be a frustrating situation. These guys here are trustworthy and truly have their clients best interest at heart. 10/10 recommend this shop if you have a diesel in the San Diego area and want to know you will be well taken care of. Thank you Diesel Doctor and Jesse for restoring my faith in the car industry!!
