We can't say enough amazing things about Ponci's Diesel Center! My family and I were on a road trip up the California coast when our diesel truck started shuddering anytime we went over 40 mph. We called Ponci's based solely on their location, hoping for a little guidance--but we ended up getting so much more. Even though they were fully booked for the day, Ponci took the time to run a quick diagnostic. As soon as he saw the code, he realized it was something he could fix--and despite his packed schedule, he went out of his way to get us back on the road safely. His kindness, professionalism, and willingness to help complete strangers truly blew us away. Thanks to Ponci's, we were able to continue our trip with peace of mind. We're beyond grateful and couldn't recommend them more highly! Five stars isn't enough! read more

Ponci's Diesel Center - Auto Repair Near Me - Fortuna, California

WARNING !!! I took my personal truck to Ponci's for the first time for a simple repair to test the quality of their service as I was considering them to service my fleet of diesel trucks. After paying for the repair , I started the truck and saw a check engine light on (that wasn't on before). When I talked with Brad and his Mother? , they told me that check engine lights are electrical and they don't work on electrical. When I made more attempt to get them to take responsibility they responded with racial comments and laughed at me. I took the truck to another mechanic who found that an electrical plug (that they had to unplug to do the job I hired ponci's for) wasn't plugged in all the way and didn't charge me to plug it back all the way. Ponci's lost out on servicing my fleet of vehicles. NEVER AGAIN !! read more

Had an issue with a hose coming loose off the rear axle while on vacation here. Was not sure if it was a minor or major issue. Brought truck in and 5 minutes later was fixed. No charge. So grateful for the honest friendly service! read more

Great deal! Great service! Owner is a really nice guy! Had quotes on servicing my Motorhome and he blew them out of the water.... also... easy to talk with and just a nice person and company in general.... Thanks again! read more

Limped our Ram 5500 camper into Ponci's with a broken axle shaft. Two days later we are on the road again. Absolutely excellent experience at Ponci's!! My wife and I got to know the team at Ponci's and were more than impressed. Brad, Josh and Brad were excellent to work with. They explained what they were doing, explained up front how long parts would take to arrive and they were totally correct. I found their labor rate to be right on par with what you should expect experienced and talented mechanics to be worth. AAA+++ read more

Driving up through Humboldt into Eureka at 2am, #6 injector quit on my 2005 Ram HPCR Cummins diesel. I patiently waited until morning in the pouring rain and called around for some much needed mechanical assistance. Only two shops in Humboldt offered to help, Ponci's assured me over the phone that they would take care of me, I had my truck towed to their shop, and Ponci's had me back on the road in a few hours. Thank you Woody and crew for all your help and assistance. I called a dozen or more shops in Humboldt including Cummins, and no other shop in the area offered the technical assistance and expertise that Ponci's offered over the phone. Ponci's is professional, knowledgeable, and they go above and beyond for their customers. Thank you Ponci's Diesel Center in Fortuna. Awesome service! Highly recommended! read more

Old Blue is a 1990 F250 Diesel non turbo. I bought it new and it's a work horse on the ranch. I needed a little more kick under the hood so a friend told me to call Brad at Ponci's Diesel in Fortuna California. So I called Brad and he recommended a Banks Sidewinder Turbo kit. He went over the details with me, we made an appointment and brought it up on a Tuesday and picked it up on a Friday morning, and let me tell you folks Old Blue has more guts than a slaughterhouse. Brad was spot on in explaining what this Turbo would add as far as power to my pickup. Ponci's is a family run business and I had the opportunity to meet his wife and daughter. I tip my straw hat to Brad and company and can't thank them enough for their wonderful service. Dave B (Bad back) read more

Found the staff to be quite knowledgeable and I'm happy I brought my Chevy Silverado 2500 HD to Ponci's They added a larger transmission pan to my Allison , and after towing my 12,000 lb 5th wheel I'm glad I followed Brads advice on setting my truck up to tow . Would recommend this business read more

Spent 3100 at poncis to have them put new injectors in my truck and valve cover gaskets only to get my truck back running worse than it did when I brought it in there. Also the pcm is not the right one I have a manual and the one that I have know is for a automatic. So I took my truck to 707 automotive and when they put the valve cover gaskets on they pinched the main wire so one side wasn't even working and the valve cover gaskets were cheap ones they couldn't even put the ford ones on. I don't recommend anyone going there. I have never had so many issues with my truck like I do know this place is a joke and over charge read more

Over the last three years I have spent about $60,000 at Poncis diesel on three different trucks. What I've learned after failure after failure after failure is that they cannot even install rear drum brakes properly and after pointing out they were installed inproperly they did not tell me that they would fix them for free. So I called Napa got fleet break pads instead of the cheap shit they put on my truck and installed them myself next-door at busted knuckle. I got a custom built transmission from poncis that cost me about $7000 and it made it 8088 miles before I had no reverse. $3500 later I was told by Arcata transmission that it was not built properly. I've had the transmission for 15 months so it was three months out of date and 4000 miles underneath the warranty. I was told to take it out bring it in and they would throw some scrap spare parts and do it to make it work again. This is not how you run a business, I'm a contractor if you screw up you make it right and eat the cost. The gasoline truck that went in there got a new jasper engine and new jasper transmission the main reason that it was getting the new engine was because of an overheating problem, which never got fixed. it's been back in the shop three times for the engine and it's going back in the shop for the fourth time for the transmission which is getting pulled out a new one put in. I'm sure that it will be installed improperly so therefore once again back for more warranty work but don't forget you will pay full price on labor for the warranty work so they're getting paid again to do nothing. Good luck, My suggestion is to take it to any shop except Brad Poncis diesel Jeremiah Anderson, Anderson Construction I had to give one star ,they don't deserve it read more

Very disappointed in their ability to work on my Dodge Ram 2500 diesel. Took it in a couple of months ago to Ponci's to fix a transmission leak. After they "fixed the transmission leak" I picked up my truck and drove home. Next morning it was still leaking...I called them and brought my truck back to Ponci's for a second attempt at "fixing the leak of transmission fluid". They claimed they found a different leak, charged me MORE $, claimed to fix the leak, asked me to pick truck up. Again, after getting my truck home, it STILL LEAKS. These are 3 hour round trips to Ponci's- and they don't even care if they do their job. Extremely disappointed in both their abilities as mechanics and with their customer service. I'll post more after their next "fix" read more

We live in Santa Cruz, CA and as usual, when we get as far away from home as we are going, something breaks. My 2000 Ford F250 7.3 diesel was having electrical problems. The alternator was not charging the batteries. I'd had the battery cables replaced recently at home. I pulled into Ponci"s pulling a 30 foot travel trailer. They took me right in and found the new cables, where they attached to the battery were not the type required by a diesel, which needs lots of battery power to start. The cables were loose, not making good contact. They could have told me the alternator was bad and I wouldn't have known the difference. These guys are honest and they know their business. If you are local to Fortuna or traveling through and you need an honest capable mechanic, these are your guys. Dennis Mozeleski read more

They charge a lot more labor time than a job actually takes and even though they don't like working on older trucks instead of being honest they'll overcharge you and piss you off so you don't come back. Also very bad communication with the service writer.Very inexperienced and incapable of answering simple questions. A big part of the problem. read more

Awful! Just awful. First they installed my exhaust brake wrong then charged me FULL PRICE plus the extra hour and half (250$) they spent trying to figure why the installed it wrong!. At the end of the day I was 750$ in the hole with an exhaust brake installed the wrong way! On top of all that they had the nerve to act condescending like it was my fault they did a terrible job. Go ANYWHERE ELSE! read more

If you have a diesel truck this is the shop to go to. Extremely knowledgable and helpful owner and staff.

Ok!!!!! I know there is another review with a guy and a 30ft. Travel trailer and I have a dodge 2500 ram diesel and a 30 foot Surveyer.... But with that said, I started having what I thought was a fuel starvation issue about 70 miles south of Fortuna. I thought I would never make it to Fortuna. I called Ponci's and they said they would look at it even though they where booked for 2 months out. Remember this was the Thursday before the July 4th weekend. They replace the TPS and I was back on the road. They where fair and saved my ass!!!!! Thank you Woody and the guys!!!! read more
