Very nice people and very professional place, my truck broke down up the road from them and I was able to limp it to their parking lot and was towed to the garage of my choice, would definitely recommend

⭐️⭐️⭐️⭐️⭐️ Great service and very friendly people I came to this truck/trailer service because I had a small air leak issue on my tractor. I was hearing a “hissing” sound and wanted to make sure it wasn’t something serious. The technicians checked my truck carefully and found that it was just a very small air leak. They fixed it quickly and professionally — and surprisingly, they didn’t charge me anything at all. The staff was extremely kind and welcoming. Inside the shop they have coffee, sugar, and a comfortable waiting area. The place is clean, organized, and makes you feel comfortable while you wait. They treated me with a lot of respect and honesty. I was really impressed with their attitude and service. I highly recommend this place to everyone. Great people, great service, and very trustworthy.

If I could give a zero star review I would. We came to PA from Virginia Beach and we had some issues with our valve stems on our trailer. Mars is right next to our hotel so we went and talked to them and made an appointment for 7 AM the following morning, we waited in the parking lot for 20 minutes, we called the guy, he said he would be there in 10 minutes, after about 10 minutes this clown, John, called us back and said he can't help us, they're too busy and they didn't have the correct valve stems. If you knew you didn't, why would you make an appointment for us? So here we are now, supposed to be on our way back to Virginia Beach, driving all around town looking for a tire shop that can help us. Save yourself some time and stay away from this place, highly unprofessional. Also, I'm pretty sure they have the correct valve stems, they work on 18 wheel trucks ?

I don't know if it's just us or if it happens to everyone, but this is what happened to us. Our driver got stuck on a hill, the police came and we called these guys. I asked several times for a tow to come and change the fuel filters to see if that would help. I got an affirmative answer to my request. But in fact only a mechanic without a toving came and he supposedly changed the filters but it didn't help and the police had already called their toving for which we paid a huge amount of money, a day later the driver told me that they hadn't changed the filter although it was on the invoice from these guys. These people are irresponsible and because of them we spent a large amount of money, I HIGHLY RECOMMEND NOT TO USE THEIR SERVICES, terrible service and deception

Very nice place with great people. The truck stopped on the road and we had to look for Roadside service. They arrived immediately and tried to help us as much as possible and unfortunately had to tow the truck. They towed the truck to their shop and were able to replace the high pressure fuel pump in a few days. In addition, they allowed us to park our trailer in their parking lot and it stayed there the entire time the truck was being repaired. Very nice clean place with great people. It was nice to work with them. Excellent work.

They were great when the truck broke down. Came by towed it. Billed for service. Didn't complete the repair. With in 30 min of getting back on the road the DEF Exhaust light came back on. Putting the truck back in limp mode. They had the truck for a month. Didn't fix a thing. Had to put a battery charger on the truck to get it started. When I limped off the road I went strait to a auto parts store and got the batteries checked. Dead cell. If they weren't going to fix it. They could have at least said so and sent it to another shop. Not jerked us around for time and $$$. Really disappointing. Frustrating. Unprofessional. If you break down. Call some one else. Don't waist your time.

Mars Diesel was dispatched to me this morning for a roadside breakdown VERY early in the morning. Brett was the technician that came out and even before he arrived he was excellent! He called to confirm my location and the issue and gave a great estimate on arrival time. Once he got there, the issue was fixed within 20 minutes which included the time it took for my truck to rebuild the air it lost. Overall, such a pleasant experience thanks to Brett’s professionalism and knowledge! I always appreciate the mobile repair techs!! Thank you Mars!

The best shop I’ve been to, wish they were located in NC! Truck derated, def light blinking, had so many engine light codes it was embarrassing lol. They got me up and running in a few days. They also took and picked me up from a hotel (didn’t have to do that at all). Thanks Trent! Thanks to all the good people at Mars Diesel! Nice people, reasonable prices and quicker than most shops considering what I got done. Great family business!

OMG, what can I not say.I would give 10 stars to Mars diesel & Trent their were the best!! Our RV broke down along I-81 and I called numerous RV mobile repair places for assistance none were able to help, either closed, or would only take appointments ( appointments for mobile service???) Trent answered and I explained our problem, he said “ no problem and he would have someone there within an hour. Mark ( if my memory serves me correctly) arrived , analyzed the problem and had it repaired quickly! They guys were a godsend, since none of the “ mobile “ RV repair services could help. Highly recommend these guys for service, emergency or otherwise! Thank you again for outstanding customer service!

Unprofessional, rude and not reliable. After multiple phone calls requesting towing services and being assured the truck will be towed in time in the next morning, their driver never came to pickup our broken truck from the service plaza, and NOBODY called. I called them myself four hours after the truck supposed to be picked up and was told, at first, that the driver was on his way to pickup the truck ( 11:00 am instead of 7:00 am... But ok ), and in a couple of minutes the same lady told me that their truck broke down and nobody will be able to pickup the truck at all!!!! And there was no apology or any phone calls from their side trying to at least explain why they couldn’t pickup our truck on time and why we found out about the delay when we called in ourselves a few hours later. I spoke with a few people from their company, including the owner, the night before and everything was confirmed and arranged - the keys’ location, timeframe of their driver’s work, hourly pay, and even the type of payment. They didn’t want to accept the credit cards (which I also found out about when I called the third time a previous night to let them know where the driver left the keys, although had arranged for credit card payment when I was requesting the towing services, and even had been waiting for the credit card authorization form to sign), so we agreed to pay with cash on delivery. The worse thing is that we waited for 16 hours for nothing, and, I believe, that if I didn’t call myself, they wouldn’t even bother to inform us of their changes...one word -ridiculous!!! It’s a shame for the so-called “reputable” company to treat their customers like that, and it’s totally unacceptable. If you didn’t want to work with us from the beginning (this is how it looks like), you should’ve just told us that you were not interested. Others have business too and, due to such unreliable services like that, they lose their time and money. Absolutely not recommended!!

Mars Diesel is by far a very reliable shop. The Freightliner Cascadia I run began having DPF issues. After a few hours I was back on the road and headed home. Not only did the correctly diagnos the problem. They agreed to do a temporary fix to get me home. If you are in the area and need help, Mars would definitely be my first shop I would call. In the future I look forward to seeing that pretty blue peterbilt heavy wrecker running up and down the road towing trucks.

Mars Diesel is an outstanding diesel repair shop! My wife and I were traveling through PA on our way home to Floresville, TX and had some major issues come up with our vintage Newell motorhome. The engine had developed a cracked head and we also had a steering problem. We needed to be towed to a repair facility. After a repair shop in the area told us they couldn’t even look at our motorhome for 5 days, we contacted Mars Diesel and were told they could look at it that day. The tow was complex and we didn’t arrive until late that night so we stayed overnight in the parking lot. The owner, John Mars was there to greet us first thing the next morning and they immediately got to work. The repairs included an in-frame overhaul of our 8V92 2 stroke Detroit Diesel. Most mechanics don’t even know how to work on 2 strokes but John is very familiar with them. They did a thorough, high quality job and used only the highest quality parts available. John apparently has many supplier contacts that allow him to find some very hard to find parts. Our steering problem was very difficult to diagnose as it was caused by a small part in the hydraulic pump that had been placed in upside down by a mechanic in the past. Amazingly, John figured this out after taking the pump apart and carefully analyzing it. We could not be happier about our experience with Mars Diesel. John Mars is an extremely knowledgeable and skilled mechanic. He’s also a great, caring guy. All of the employees are very professional and friendly. The facility is beautiful. Our tow truck driver, (a former diesel mechanic) who works for Blue Grey Towing, was impressed with how well the shop was equipped to deal with diesel engine repairs. The work was done in a reasonable amount of time and the cost was also reasonable. I highly recommend Mars Diesel if you are in this part of the country and need to have repairs done on your diesel vehicle.

Stay clear of mars diesel, they are crooks. I took my truck to them for issue with fuel system. $4000 later the issue still occurred the next day i left there shop. My truck brokedown in New york, notified them and he actually admitted that he figured my truck will Shut down again but lied saying prior to the breakdown my truck was repaired and ready. Then hung up on me. They're nothing but a bunch of crooks. And all the owner is doing taking people money to keep up his toys at home. Took my truck to volvo and they found out i didn't need none of the repairs they so called did. It was the injector cup seals leaking. Damm thieves. CROOKS EVERYONE STAY CLEAR OF THIS SHOP.

These guys did a great job installing a new turbo and resealing the rear differential cover. And all at a fair price. I would definitely take my truck back here

Been an o/o for 10 years now, and i know that getting emergency repairs done away from home is usually expensive... especially after hours and on holidays. My truck stopped going thru the regen process on its own, and would not perform a parked regen either. My wife and I contacted John about bringing the truck to his shop early in the morning ON July 4th! Not only did he answer, after describing our problem to him he told us to come right over. I totally expected him to say we had to wait until the following day. We arrived at his shop around 0730 and John was there waiting for us, coffee in hand. He did what he could to troubleshoot the issue, and called a freightliner specialist to come over (ON July 4th!) and assist to make sure he was accurate in his assessment. By 11am they had discovered the problem, got the truck to go thru the regen process multiple times to completely clean out the DPF. He discovered that the clutch switch had gone bad, and gave us a work around to keep the the truck going and to be able to perform parked regen whenever needed until we could get back home to our mechanic to have the necessary components replaced at a reasonable cost. While John and his colleague worked on our truck he took my wife and I to his shop's break room, cranked the a/c, turned on the TV, and made sure we were comfortable. The shop and the property overall was emaculate and well organized. And after all was said and done I can say that our invoice total was MORE than fair, considering the position we were in. Definitely recommend their shop, and will definitely visit again when we (or any of our drivers) are in the area in need of anything for our trucks. Great guy, great shop. You're in good hands at MARS DIESEL! Thanks John!!

The owner is an good honest guy. I bought the wrong part at an salvage yard before finding this shop. Once I arrived at the shop, the mechanic discovered I had the wrong part. The owner found the correct part for me. The mechanic that worked on my truck repaired it in a very timely manner. I found these people to be very honest and help. Great people and a great shop. I would recommend this shop to anyone in the area.

As for the defense of Mars Diesel, the $7,200 charge was to replace the transmission, clutch, fly-wheel, and mounts. The transmission stated in the reviews below failed because of the customer's transmission oil cooler lines failed and dumped oil out of the transmission. The customer did not shut the unit down when he could no longer shift. Mars Diesel offered to tow the customer's unit to our facility but the customer refused the tow.

This place sucks. I paid 7200 for a transmission. They messed up I broke down 200 miles from their shop and they won't warranty their work. Stay away from these people
