Went Harmonic Diesel after the dealer charged me $600 to tell me I might need a new turbo and NOx…read moresensor and was not sure if that will fix the problem. Got my truck out of there and call Salvador. He diagnosed the turbo being bad as soon as the hood was open. He explained that it was starting to blow oil back into the input and demonstrated how you can easily tell. Cause was leaking seals. Then plugged into the trucks computer and sure enough the NOx sensor showed bad. Less than five minuets. Had him do a lot of other work and he completed it in three days. Cost for all the work was just about what the dealer was going to charge me for a turbo and NOx sensor. Salvador is honest, hard working and knowledgeable. His prices are very fair. Worked performed was a new Garett turbo, OEM NOx sensor, change transfer case fluid, change oil and filter, change transmission fluid and filter, air filter and cabin filter, new brake fluid, change out the OEM fuel filter for a .5 micron CAT filter, and drain and change the coolant.

I'll absolutely be bringing my truck back for anything it needs in the future and will recommend NorCal Diesel to everyone I know. Truly a great experience working with you guys!!

Joe answered my call quickly and provided an estimate, and could be available as early as next day. I was initially a tiny bit worried about some of the reviews I read about scheduling/showing up, but Joe put my worries at ease and communicated with me within a reasonable amount of time and showed up when he said he would. He and his partner were communicative, kind, trustworthy, knowledgeable and skilled at what they do. They worked on our car repair in the pouring rain with no complaints! I would recommend them again and again and again. The mobile aspect was extremely appreciated and so valuable - we didn't need to worry about a tow or timing logistics to get the car to a shop before they close (because come on, most people work!) Excellent value, fabulous service, terrific work. Thank you Joe, and happy holidays!

He has super prices, and I have an appointment to bring back my Dodge for repairs. This business is family owned, hard working and honest business folks. Did you hear that honest? For Auto and Truck repair? I am hesitant to yelp this business, as just word of mouth, has business has grown. I was surprised he got me in promptly for diagnostics. I highly recommend bringing your vehicle to Lakeside Auto and Diesel repair! Screw the dealers! I brought my diesel into a Redding dealer a few years ago: They recommended/pushed for services that were not needed, overcharged me, and overfilled the differential! What a ripoff that was! All I can say, YEAH Ernie! I mentioned to my Beau, there is one special place in Heaven for this gentleman! AMEN

I'm a newbie to RVs and took a recently purchased '94 Foretravel U240 to North Valley Diesel…read moreyesterday and could not be happier with the dedication that Jeremy put into helping me get the CARB Clean Truck clearance. There was a glitch in communications between my CARB account and the NVD upload, but Jeremy went well above anything I could have expected. Customer service matters! And that is exactly what I got for my dollars from Jeremy and NVD. There is no doubt that any other shop would have turned my wallet inside-out based on the CARB difficulties, but Jeremy was straight up honest and really wanted to see me through this. The problem was with CARB (pretty sure a fault with my account setup - my mistake), not NVD. I will say, CARB did properly, and quickly, communicate with NVD and they eventually worked it out, so kudos to BOTH of them. I very highly recommend North Valley Diesel in Yuba City. You get what you pay for along with a lot of honesty, proper communication and effort to get the job done. In my own business, I appreciate communication and professionalism, and that is what Jeremy provided, so thank you! Dan

Never going to use this place again. The younger tech, John is awesome (he replaced our fuel…read moresolenoids in the past). John should open his own shop. The older tech, Jeremy, is a straight up a-hole. He his attitude, disrespect is just down right unprofessional. He won't listen to customer complaints especially if you are a female. Myself and my wife were diesel mechanics in the military and he treated her like she is lower than whale crap on the bottom of the ocean. He treats people like they don't know anything. I can see him scamming ladies that use them because they 'don't know vehicles'. He just cost this business a ton of money. I was going to use them for front end work, APPS replacement and turbo replacement... Not anymore! If you like being treated like garbage, use this shop. If you want to keep your dignity and sanity...go to NorCal Diesel on N. Polora. Juan values his customers!!

She also was involved in a trailer sale with Sean and that went very well with fairness and respect. I blew the turbo on my 2005 Ford F350, my fault, and had to have the vehicle towed to the shop while I was out of town. Sean and his team were not only fair and accommodating, but they are also very knowledgeable and performed excellent service on my vehicle. Sean understood the need for a fair price and understood that all things can't be completed at once without a ton of cash. I can not thank them enough and recommend them very highly for any of your diesel needs. Beyond a Five Star business.

The day before we stumbled on the amazing team at Roberts Automotives my husband and I had flown up to Washington to collect our RV (which had been stuck there for nearly 3 months being repaired after we hit a deer while exploring Washington's National parks over the summer). On day 2 of our road trip back to Los Angeles from Washington, our newly repaired A/C stopped working! It was late in the afternoon on a Friday so we knew finding a mechanic willing to help us close to closing time, and in an RV no less, was going to be a challenge but after speaking with the owner Sean on the phone we trekked an hour out of the way to visit his shop in Chico. Not only did he and his guys stay after hours to help us but they were also the friendly faces we needed after a stressful day on the road. They took amazing care of us, communicated in detail what was wrong and how they were going to fix it, and even took us on a road test to ensure all was working as it should before we headed out. We even got a call from Sean after the weekend was over to check in on us and make sure we were able to make it home safely and didn't have any further complications. This is SERVICE AT ITS FINEST. For Chico locals or fellow travelers in need of a trusted mechanic trust us, with this team you are in great hands.

I brought my 2002 GMC Sierra 2500 Duramax to him with multiple issues and he was excellent from start to finish. He diagnosed a bad vacuum pump, found an AC compressor leak, replaced glow plugs, and fixed a broken transmission dipstick tube. He also cleaned up a bunch of oil underneath the truck while he had it apart. What really impressed me was how transparent he was. He sent me photos, videos, and updates explaining exactly what he was seeing and what needed to be done. No guessing, no pressure, and no unnecessary upsells -- just straight, honest communication. The AC is now blowing ice cold (around 40°), the truck runs great, and everything was done at a fair price. He even skipped charging labor on a small part replacement, which says a lot about his integrity. It's a family-owned shop that he runs with his dad, and you can tell they actually care about doing things right and treating customers fairly. Good diesel mechanics are hard to find. Honest ones are even harder to find. I'll definitely be bringing my vehicles back here and recommending them to anyone who needs diesel or auto work done.
