Very professional in their communications with me in estimating the costs, the time they needed, their findings as the service progressed, and recommendations for follow-up service. Top-notch customer service as well as automotive service. read more

The staff and service at Deer Park Diesel is fantastic. They are very knowledgeable, personable, and all very compitent in what they do. They always go above and beyond to help and provide detailed information on the problem or routine maintenance. The cost is always outlined before the work begins and are good at communicating any changes as they are working on the vehicle. HIGHLY recommend Deer Park Diesel to anyone looking for quality service and people at a fair price. read more

Outstanding, Friendly and Professional service. They dedicate time to explain in great understandable detail of any problem found. They instill confidence and trust that their maintenance performance is second to none and at a fair cost. I have taken my diesel in for preventative and regular maintenance and have been extremely satisfied with Deer Park Diesel's performance. And that performance deserves many more than 5 stars. read more

I do not recommend anyone do business with this company. In short, this was the worst, most unprofessional, exhausting experience I have ever had with a company. Communication was beyond poor, and my experience with Marcus was unprofessional and disrespectful. He quoted me four days, which turned into over three weeks. This was due to negligence. I was looking forward to getting my turbo replaced on my Ford F250. I contacted Deer Park Diesel prior, and from the conversation, they were excited to do the job. I was told by Marcus that I would receive picture updates and phone calls regarding progress. I was pitched an excellent experience. Only for nothing to be done as advertised. I was very excited, as this is something I've wanted to do for a few years. I was quoted around $1600 for labor, around $7000 total, and four days of work. When I dropped my truck off, I thought things were set. After three days, I hadn't heard from the company. I called multiple times with no reply. I found out the day before I was supposed to pick up that the parts were not there, but they had already taken the truck apart. Who in their right mind takes apart a vehicle without the parts in the shop? Once the parts did arrive, not everything was there. Shipping caused further delays. I called and texted multiple times, I received either no reply or a reply minutes before they closed. The day comes to pick up the truck, three weeks later, and I am told I own an additional $900 for labor. I had already paid in full. At this point, I feel screwed over and taken advantage of. When I expressed my concerns and poor experience, Marcus, with a smirk on his face said, "I did everything I could". No, Marcus, you did not. You should have called me the day I was supposed to drop the truck off and let me know the parts were not there. The team should have checked the parts before attempting to install them. You should have never allowed a vehicle to be taken apart without parts in hand. You should have communicated with me at the bare minimum. I do not have an extra vehicle and was out of a vehicle for three weeks due to negligence. I had to reschedule with a tuning company multiple times, and in the end, told them I had no idea when I would have my truck back. I was never expecting a discount, but being told I own more money felt like a slap in the face. I don't feel confident in the work that they did, they produced nothing but doubts and poor service. I don't want Deer Park Diesel to "talk it through at our next team meeting". I want them to make it right, I want them to correct their obvious negligence. They made multiple mistakes, and they need to take accountability. Marcus blamed the three-week job on the turbo company and shipping delays. He told me that he didn't have all the right parts and that he couldn't get a hold of the turbo company. I called them myself, I was able to speak to someone right away, why couldn't he? Did he lie to me, because he hadn't tried yet? Before dropping my truck off, I paid for the parts. Why were they not ordered before I dropped off my truck, were you hoping the turbo fairy would drop them off after my truck was taken apart? Why didn't you offer to have my truck put back together when you couldn't get the parts? Why didn't you do anything to make this less of a terrible experience? read more

Initially spent over 6k to get my fuel injectors replaced. Since then I have had to go back and spend an additional 5k with a different shop. Deer Park does not stand by their work at all. They told me they would tow my vehicle to their shop, but they didnt show up and they blamed me for it. If you dont want to fix your vehicle twice, dont go here. read more

Always informative and friendly, very thorough on there inspection and do an excellent job explaining issues/potential problems.

300 miles after an engine repair job that ran over $6000.00 , my truck blew a steady stream of oil onto the road. Towed the truck back to Deer Park Diesel to fix this problem, They fixed the issue but I was told it wasn't their work that failed. It was an oil pressure sending unit. Apparently that isn't part of the process of installing a new high pressure oil pump... During the following conversation with I assume the manager/Owner about this. I told him on day of delivery I noted the pressure gauge was not working. I asked him why the sensor wasn't checked when the gauge wasn't showing pressure. He told me that should of been seen by the tester that its the first thing they check. They would have corrected it. Well it wasn't operational when I drove it home. Did the manager check out the rig? Of course not, someone that works there did. So the manager, who didn't do the work, wasn't there during the test, basically called me a liar. I saw what I saw, it didn't work, I was there, he wasn't. After a few more words he tells me I should of called the shop when I saw it wasn't working. Yep I should of. Shop was closed when I got home, Its not a daily driver its a work truck. I didn't drive the rig again till I plowed the snow. Noted the gauge again. Shop is closed on weekends. Ok excuses are like what, Yes if I had called maybe I would of avoided the tow, But IF the mechanic had done his job and checked the sending unit and actually checked the gauges I would of missed that tow as well. Then after a few more words I get told the sensors go bad all the time, WELL FOR CRYING OUT LOUD, if the professional that you pay to do a job, one you trust to have the knowledge to do the job right doesn't mention a $20 part with a history of failing often in the we recommend these actions, then how much more wasn't worth bringing up. Now I have concerns on the rest of the little parts that could result in breakdown. This part cost me over $200.00 in shop charges, and close to $300 in towing charges, and two days of down time during a job I needed the truck to do. Did the manager consider the customer invested over $6,000.00 in belief that a professional job on his truck would be done right? Did he consider that anyone spending over $6000.00 in his shop that has a breakdown 300 miles later might be upset and work with the customer? Like offer a compromise, customer pays parts shop absorbs the labor? No he simply infers the customer is a liar trying to get free work . I can't prove the mechanic didn't check the gauge. All I can be sure of is the gauge didn't work 5 mins after I left his shop. I don't lie, hence the reason for this review and a company I thought was honest has a price on that honesty..... $200.00 Seems a cheap price to sell the integrity of you company name. There are other repair shops in the area I had this experience with this shop. If you go there and something goes wrong, well you should of listened to this review. read more

Went above and beyond to help me out. Might have taken a few extra days to get this fixed, but in the end a great solution!

Took my truck to Deer Park Diesel to get an in-depth inspection and schedule a plan for preventive maintenance and repairs. The inspection was prompt and matched the issues noted when I purchased the vehicle several years ago. The recommended service was only what was required and cost was clearly stated for each service. I will be using Deer Park Diesel to maintain my 19 year old dually for many more years of operation. Thank you! read more

These guys are probably some of the coolest most professional folks I've met in the business. From the East coast to the West. Guys there are definitely enthusiasts not just trying to burn your wallet. There automated update system allows you to take a look at what the mechanic working on your truck is doing (showing anything coming up in inspections or whatever there doing) Honestly one of the coolest things I've seen as far as giving the customer a peak and live update of what's going on. HIGHLY HIGHLY recommend anyone checking out these folks for any of your trucks needs. THANK YOU DEER PARK DIESEL!!!!! read more

Being a woman, I am skeptical and cautious about who I hire to work on my 2004 Dodge Ram Diesel. I used Deer Park Diesel in 2012 on two occasions and was very pleased with the services I received. So, recently, when I heard a noise that shouldn't be there, I knew that the only place I wanted to take the truck was Deer Park Diesel. Thankfully, they were able to get me right in and on the test drive, they evaluated the noise and my input, took the truck in the shop, and diagnosed the problem. I feel very confident about accepting their diagnosis and suggestions since I believe that they are fair and trustworthy. I highly recommend this shop! read more

The folks at Deer Park Diesel always treat us right and so quality work. They have done our yrly service on our motorhome last 4 yrs and am completely satisfied! Good Job!!!! read more

My Alfa motorhome lost engine power while we were staying at the Deer Park RV Resort. Jake came out and tried to repair it at our site but the problem was worse than he thought. We had it towed to their shop. I was amazed at the knowledge and helpfulness of Jake, Marcus, and crew. They found the problem, repaired it, and got me back on the road. I will not hesitate to take my vehicles to them. The shop was great in every way. read more

This business is attached to a Car Quest parts store! Perfect for what ever you need. Made an appointment took my Motorhome in a little late, they took it right in! The guys here are so polite and professional! Shout out to Greg who is an encyclopedia of knowledge and a very helpful person. All the staff were wonderful they got the rig in found an reason for low oil and we were out of there in less that 3 hours! Thanks Deer Park Diesel!!! read more

Great experience every time we need service. Everyone we dealt with were able to communicate problems and required repairs at a level that was easy to understand. Glad there here! read more

Have been taking my cars here for years and they are amazing! Jacob is so nice and friendly at the front desk and Jake is a super honest and friendly mechanic. Very nice to women and not condescending. Never push anything on you you don't need and will always work with you on payments, etc. They are family owned business and they are all very nice! Love the Schulers and their great work! read more

We took our truck to them and they said we had to replace a heater that we have a receipt from them that they said they replaced in February. Now they say they didn't replace it and it will cost $1,000 to replace. How can a business run like this? They told us it was replaced and we have a receipt for it. This isn't the first time we had a mix up with them. I don't know why we went back. Go anywhere but here! read more

I set an appointment for 9:00 am with a small list of tasks to complete; replace fuel filter, test intake heater, fix coolant leak, check coolant rating, check/top off fluids and grease everything. Promptly dropped the truck off at 8:55 am. Asked 3 times for a estimate on cost and time mechanic would not provide either. Showed back up at 12:30 pm and the only thing they had done was replaced the fuel filter and tested intake heater. Mechanic informed me both differential fluids and transmission fluid needed to be replaced. Proceeded to replace rear differential fluid. Mechanic told me he would put an extra guy on it since I was there waiting, like oh gee thanks I'm flattered. When they we finished I checked under front end nothing had been greased, checked under the hood and coolant was low. Asked him to finish greasing and topping coolant, took 40 minutes. Asked what the coolant rating was, said they forgot to check. Won't be going back. read more

Knowledgeable mechanics who do excellent work, and show you what they're doing and why. Very competitive prices, and if you ask for a price on something, and they don't think it needs to be done, they suggest as much, rather than just doing it. Jacob at the front desk is knowledgeable, thorough, and very friendly. Deer Park is fortunate to have such an excellent shop. read more

The professionalism and customer service of this shop is outstanding. We were traveling through the area in our motorhome and had trouble with the auto breaking system. When we stopped in unannounced the shop was completely full and booked for the next couple days. The staff made adjustments to the schedule to get us in so we weren't stranded. They had a part shipped up from Spokane within hours and we were back on the road home by the evening. Great shop, I would highly recommend. read more

have nothing but great things to say about my experience with the guys at this shop...I bought a truck in October 2019 from Dave Smith Motors that was supposed to be in top running condition only to have in the end lifted heads bad injectors and cracked pistons among other small things.. The guys at deer park diesel treated me with the upmost respect and compassion and care anyone could ask for in my situation. They were upfront honest and had the integrity that the dealership Dave Smith Motors failed at along with the honesty.... This business and group of guys are 100% legit and will be nothing but grateful for such a great experience with such a stressful and emotional draining time with the purchase of my truck and the engine failure of the truck within weeks... Seriously folks dont hesitate this is where you go!!!! Thnaks everyone who worked on and or delt with me on this rough experience with this girls broke down diseal from Dave Smith Motors read more
