Our heavy duty truck needed an emergency repair after it incurred damage on the freeway . Pulling a 43 foot trailer with dogs and a child in tow made it stressful! George fabricated a repair of a part that is no longer available , got all of the parts and had us back on the road in about 24 hours! Despite no appointment and his busy schedule he got us going for a fair price! He even made room for the trailer so it would be safe . Kim communicated every step of the way! She let me and the dogs wait in the office and made sure everything was flowing smoothly!! For hours !! and made me feel welcome. I would recommend regular service and major repairs of heavy trucks to use this company ! Veteran owned is a bonus for me.

Unfortunately, his repair barely lasted 100 miles and I limped the rest of the way to San Diego. I called MPower since they were one of the few certified Cummins engine repair facilities nearby and made an appointment. Tom was ready for me when I arrived and quickly pointed out to me that the mobile mechanic had broken the support for the sensor and he had tried to "fix" it by using electrical tape and a zip tie. Tom warned me that he would probably have to drill a new hole to mount the sensor properly. He did this and was done with the repair to my RV in a very short period of time. I drove the RV back to my San Diego home and immediately noticed an improvement in the sound of the engine now that the system was properly sealed. I will certainly return here for future engine repairs.

When it's hot out it will start but then within an hour die. Been happening for about a year, we tested it with the door open and it would run most of the time indefinitely. So anyway when I brought it in I voiced all this too the service advisor. I told him to make sure the mechanic tests it with the door closed because we know with the door closed it's overheating, which is the problem I was trying to solve. They charged me for the technician to look at it and then run it for 2 hours in an air conditioned bay with the door open. So of course it didn't overheat. So they call me and go oh no nothing's wrong. So I question them about it sure enough they ran it under the wrong circumstances. So then the service advisor goes back out turns it back on, runs with the door closed sure enough within an hour it dies. Well long story short almost $700 later they tell me yep it's overheating. Yeah I know that that's why I brought it in, what is the diagnosed issue? We're not sure but we should probably just do a thousand hour service cuz that'll cover everything. Well the generator only has about 850 hours So basically they just wanted to throw parts at it. I can take it to any generator or RV shop and they could do that cheaper than what Cummins would charge. I took it to Cummins for a targeted diagnostics But instead got stuck with a huge bill and no more information than when I brought it in. Second issue of the three issues they fixed.. I have a hydraulic parking brake that's connected to the drive line. They had to repair a hose that was leaking. Well after they repaired the hose they didn't add any of the lost hydraulic fluid into the reservoir. So the very first time I went to put the parking brake on it wouldn't engage. So I'm sitting there at my house trying to call my wife holding the brakes so she can come in hold the brakes so I can go out and diagnose the issue which was the reservoir was low on hydraulic fluid. I honestly didn't bother to call them about anything I mean how can you trust him if they don't even bother to fill up a parking brake reservoir which keeps the coach from rolling away. So don't waste your money going to Cummins thinking they know better, at the 200 plus dollars an hour your not getting any better service than anywhere else.

Higher viscosity leads to higher pressures which lead to seals leaking and failing. I'm really surprised you haven't researched this. How about the leaking oil filter a day after install?

How about the scratches from resting my tires on the paint of my car? Lazy and inconsiderate.
