Broke down Saturday night in St. George Utah and reached out to Spencer. Was willing to go and fix our belt but never showed up or answered calls. Driver was stuck waiting all night. At least a heads up that he wouldn’t show up would’ve been nice. No answer the next day as well. Would not reconnect. Very unprofessional

Spencer has had my car for over 6 months now. He won’t respond to my messages/calls. For all I know, he’s already sold or parted out my car. I unfortunately have to report it stolen at this point. Please don’t trust him with your vehicles.

STG mobile diesel repair did a great job on our truck and was able to get to work on it very quickly when most other diesel shops were weeks out. Did a great job and were very friendly.

I contacted this company and all I ever got was a voicemail. I asked for estimates and a call back. I have received NO response and its been nearly a week. Spencer is obviously unreliable and undependable. Be afraid ... Be very afraid ????.

100% wouldn’t trust anybody else with my vehicle. Spencer is the most knowledgeable, friendly, and reliable mechanic I know!

STG did a great job!! Very knowledgeable, professional and personable. Changed our oil, checked our brakes, and fixed rattles. Honest and reasonable. So happy STG was referred to us. Will try to use them all the time in the future.

Did a great job replacing the injection pump on our truck. When a lot of shops were booked weeks out, he was able to squeeze us in and get the job done quickly. Very happy with their service.

I needed my 15 Tahoe A/C looked at so Marcus came out to our house to diagnose. He showed up on time, diagnosed the problem and topped off all fluids w/out me even asking him to. After he discover the problem he made arrangements at the drop of a hat to get our Tahoe into their shop to fix the A/C. Here’s how you keep customers and stay in business:Trade KnowledgeShow up on timeCommunicationJob efficiencyProfessionalismALL of these where hit out of the park. Do yourself and your wallet a favor and call Marcus.

Spencer and Marcus from STG were great! My Ford F-350 Diesel broke down in St George on a Saturday at 4pm, I was towing my travel trailer to Zion National Park from CA. AAA towed my truck to STG Diesel Repair. Spencer began repairs on my truck first thing Monday morning. What I am impressed with the most is that Spencer and Marcus delivered my truck to me at the campground in Zion which was an hour from their shop. They spent 2 hours round trip of their time to keep my vacation on track.!!. Spencer and Marcus truly care about customer service and keeping their customers happy…. You can’t go wrong with STG..I highly recommend this company.

Traveling on vacation in a 30 foot motorhome from Washington State we blew a rear inner tire on I-15 several miles from st George Utah. Neither AAA nor the RV insurance had a provider to help on the highway. We called the first mobile repair to help us with a blown tire and additional damage under the coach.Not only did we a phone answered immediately by Spencer, he came quickly to help us. He bought us a tire and delivered and installed it. He further investigated all of tires and provided excellent advice. And brought a helper to help temporarily fix our other damage to get us safely off the highway.Spencer devoted a good deal of his day taking care of our problems on a very hot day.He was very polite, cheerful and highly knowledgeable about everything that happened and fixed everything to our full satisfaction.He also recommended a shop for our additional tire needs.The Bill for the repair was less then I expected and I very happily paid it.Call Spencer for your emergency roadside needs!! You will be very happy u did.

My truck broke down just outside of St. George, Utah while returning back from my snowbird trip in April 2022. My HUD came up with a check fuel filter. My truck died very quickly after that, barely made it off the road. After calling road side assistance, started looking at repair shops around me. STG was suggested by just about everyone I spoke too. They dropped just about everything, had my truck and trailer towed to their shop. Marcus and Spencer immediately replaced the fuel filter with the hopes that was the issue. After 2 more hours, no such luck. Left the truck with them, and they were kind enough to drive me back and my trailer to the KOA campground just outside of Hurricane. Next morning I got the call from Marcus with the bad news. Basically, my igniters had ate themselves and my whole fuel system (sans the fuel tank) had to be replaced. Marcus located all the parts required and spent the next 10 days basically rebuilding the whole system. I can't say enough about these guys. Driving me to and from their shop, offering to get groceries or offering to drive me where I needed to go. They went above and beyond to not only assist me in my need, but to help educate me in what happened and more importantly, to keep me calm in such a stressful situation (I recently lost my husband). I honestly can't say enough about this company. If anyone ever needs help, they're the best in my books. I had one furhter small glitch on my way home, but made it safe and sound...Spencer, you've carved a great business and have some of the best of the best. Thanks again to all of you, but more so Marcus!

Spencer was a lifesaver! I broke down with no cell service! I could get text messages thru, but no calls. He helped get a tow truck for my rv rig & car trailer. He went above & beyond! Even checked up on me several times after!

Guys were great. My 6.0 wasn’t getting fuel and they had it fixed in hours. Runs better than it has in a long time. Highly recommended. Great price too
