Byron replaced my radiator and did a great job. Will return to him if another need arises.

Byron is a great mechanic. He works on my 2016 Jeep Grand Cherokee 4x4. He fixed a few problems that no one else can do or couldn't diagnose the problem. Byron is your guy. He had my car ready and running the same day. He is fair on prices and a very knowledgeable mechanic and is straightforward with you. read more

Byron was very responsive and provided great communication with updates and estimates for repairs on our Sienna. He also got the job done on a short timeline. He even made it possible to drop off after hours. Would recommend to others. Thanks Byron. read more

Byron possesses the perfect combination of Toyota & Jeep automotive know how, attention to detail, and customer empathy. Very satisfied with his work on my wife's babied RX330. One of these days my Jeep Grand Cherokee will need his talents as well. We are lucky to have him in our neighborhood! read more

My car could not be in better hands. Byron is great to work with - honest, skilled, fair and fast.

Byron is great. He has helped me with both small and large repairs on two of our cars. Great work- very professional and at a fair price. Highly recommend! read more

Ross Valley provided a lightening fast quote response to a needed repair on a SUNDAY night when my Range Rover would not start. Not only did they know what to do to fix my car but when it became aware that my car was 70 miles away and too far to tow, they gave me the answer to a fairly simple problem via e-mail (on Sunday night), which allowed me to make the repair myself. I look forward to doing business with Ross Valley in the future. read more

Easy to schedule, prompt response, and transparent service! Stop your search for an auto mechanic and reach out to Byron at Ross Valley Auto! Completing maintenance for your vehicle should be easy and reasonable and these folks are precisely that. They were honest, informative and didn't try to sell me anything more than what was needed. Give them a call! read more

Byron is super honest and straightforward. I'm a single mother who teaches full time and admittedly don't take the greatest care of my ol' battle wagon. I brought the car into Byron and asked him to take a look at a couple issues I knew were there as well as an overall checkup and tuneup. He called me while I was at work to let me know what he saw needed to be done and itemized and prioritized the financial and safety costs of each so that I could determine how much I could afford to fix safely at the time (and what could wait a couple more months). I was able to pick my car up at the end of the day with everything I needed (and more) completed. Super appreciative of an honest mechanic. read more

Honest mechanic. Fixed my problem and fixed only what needed to be critically fixed but also pointed out other issues and gave me advice on when I'd need to get them done. Highly recommend. read more

We were long time customers at Japan Auto Works and loved going to Kenzo for the past 10 years, but Kenzo retired and the level of care with the new owners has not been the same. We started searching for a new mechanic for our 97 Toyota Forerunner and stumbled upon Byron at Ross Valley Auto Repair. We just needed a diagnostic at first to identify why we weren't passing smog. Byron is super knowledgeable with Toyotas and got us fixed right up for cheaper than I was expecting. We have gone back now to do a lot of the deferred maintenance on the vehicle and decided to finally upgrade the suspension and add a 7 pin trailer harness brake controller for pulling a dump trailer. I got the car back today and I absolutely love the new ride. I couldn't be happier with the level of service and quality of work. Often in Marin you get barely mock concern for an older vehicle but there is nothing wrong with our Toyota and now it rides better than it has in years. Now that we have Byron, I know where my car will be coming for service for the next ten years, which is a relief. read more

This was a little out of our way, but completely worth it. Byron is honest, knows the ins and outs of a car, and explains everything really well. Will be going back. read more

Our 2006 Jeep Wrangler unlimited had an engine problem that other great mechanics were puzzled about and did their best to resolve but the problems came back. After replacing a number of parts that the diagnostics indicated caused the problem, the problem persisted. One part that continued to pop up was the camshaft sensor( its like a distributor in older cars). It was replaced by one of our other long time favorite mechanics. He said get another opinion. Our son recommended we take it to Byron who had many years of experience at Parker Jeep. Byron tested and like a "horse whisperer " he swapped out the new sensor for one in the garage. He road tested and engine light off. Second was the notorious Jeep "death wobble ", parts had been replaced and the wobble would recur. He replaced a suspension part and showed us how the bushing was worn. My other mechanics and a front end guy had tightened, replaced a stabilizer, new tires, alignments and after a while death wobble again. It was one part not replaced and had never been removed to inspect. Now Death wobble gone. Some other needed repairs were added. After 2 days of work, both problems resolved. It has been about a month since the work and all is great. I held off in the review to see if the two problems fixed were actually fixed. Great. Byron is down to earth. Tells you with precision what he recommends and why. His pricing is very reasonable . Big trust in Byron! He also works in all cars. Call him and talk about your issues. He will ascertain the potential cause as you discuss the problem. Byron doesn't just rely on the code reader. He knows mechanics and goes beyond relying only on the codes. Highly recommend!!! read more

My wife and I owned a 1989 Jeep Grand Wagoneer and found Ross Valley 4x4 on Yelp. I have to say that Rick (he is Ross Valley 4x4) is a great Jeep mechanic who tells it like it is. It's rare that you can find a mechanic that not only has the expertise, but is also trustworthy - Rick is both. We've since have sold the Jeep to a proud new owner, but we went to Rick for about 8 months of the 2 years we owned the vehicle. Rick did a better job than any other mechanic we went to - and there were a few of them. Rick was able to fix some old breaking things and tune up the Jeep so that it ran so smooth. I highly recommend Rick and Ross Valley 4x4. read more

This place is great! I called in the morning and brought my car in and Byron stayed late just to finish it for me. He was very honest, friendly, and worked hard to get my car back to me as soon as possible. We originally thought the alternator would have to be replaced but it turned out not so bad (or expensive) and he did his best to provide the lowest cost with high quality service! I now have a mechanic in the area that I trust and will return in the future. High recommend this place!! read more

I collect vintage Jeeps. My classic Jeeps are show winning vehicles. I have been taking my Jeeps to Rick at Ross Vally 4X4 for over 10 years now. I drive over 1 hour to see Rick because he is the absolute best Jeep mechanic in the North Bay. I don't trust anyone to work on my Jeeps besides Rick. He has decades of experience and knows every Jeep quirk and the best update to fix problems. Not only is he competent but he is a great guy who really cares about doing quality service and repair. He doesn't cut corners and will make sure your Jeep is running perfectly every time. I feel so lucky that I found him and I will take my Jeeps to him for years to come. Rick is in high demand. So expect to schedule an appointment. However, I have seen Rick resolve an emergency in a pinch if you get into trouble. What more can I say. He's the best ! read more

They helped me get an oil change and tire fixed up on a very late notice, explained all the costs and problems clearly to me, and were very generous and patient throughout the whole process. Definitely recommend if you're looking for a good, caring, and reliable auto repair shop. read more

Byron is gifted at what he does. He can fix and maintain the integrity of any car. He is also a trusted friend, which I why I sought him out to do some major engine work on my 2012 Prius-C. He contacted us throughout the process with updates to make sure we felt assured and he was transparent about everything that would need to be fixed. I have been pleased and confident with my decision to travel to Ross Valley Auto from the start. We live in Benicia, so I had a great test drive home. My car sounds, feels and drives like the day I got her. Byron did a fantastic job and saved me a lot of money and from buying a new car unnecessarily. Marin residents, you have a Toyota expert at your fingertips, and someone gifted in fixing and maintaining hybrid technology at that! If you're looking for a trustworthy person to work on your car, give Byron a call. read more

Just picked up the Jeep yesterday and thought I need to give Rick a big thumbs up. He started this one man repair shop on Drake after years as a mechanic at the Jeep dealership so he knows his Jeeps. Plus, he's always fair and I never worry about him upping the ante. He has plenty of business and doesn't play games like some mechanics. Always in and out, though it's best to make an appt...he only seems to take on as much work as he can handle...and it's a quick turnover because of that. I totally trust this business. read more

We have been Rick's customers for going on three years now and always had top notch service and great customer service and always at a fair price. My daughter took her Jeep to college this past year and when she had some trouble down in LA, Rick told me what he thought needed to be done over the phone and I was able to confirm his prognosis when the LA shop and know they were only doing work that really needed to be done and Rick told me what I should expect to pay. We are currently looking at cars for my youngest daughter and I am trying to steer her towards a Jeep so that Rick can continue to be our mechanic. read more

If you have a Jeep - Just go see Rick at Ross Valley 4X4. We have a 1993 Grand Cherokee and 2000 Grand Cherokee that he has kept in great shape. His service advice is always fair and square, you will not find a more trustworthy, skilled and pleasant mechanic in Marin. One of my GC lives in Berkeley and we still take it to Rick. We have had all sorts of other cars but our Jeeps have been the best overall family experience (even after my kids wrecked them) because Rick keeps 'em running! Many time I have told my kids - Rick is the example of the right kind of family mechanic you need in life. THANKS RICK! read more

Very reasonable and knowledgeable owner. He took over from Rick and from 2 times bringing my Jeep there, both experiences have been great. He knows his trade and is honest and fair. Since he does more than just Jeeps, I'll be bringing my wife's car to him as well. read more

Rick just fixed CheroTank from 3,000 miles away. Tank now lives at the tip end of Cape Cod and we have a terrific local mechanic but no one guy can be an expert on every make, model and year of vehicle. Tank was screwing up. Awful noises to the point where nobody would ride in it. I asked Pat, the great local tech, if he'd mind talking to Rick and together they figured out that someone (a late and not lamented Jeep dealer in downtown SF) had put the wrong fluid in the transfer case. CheroTank is now blessedly noise-free and running like its usual gas-guzzling self. Thank you, Rick. read more

I brought my 2001 Jeep Grand Cherokee to Rick after a disaster in home automobile repair. He was friendly, straightforward and came up with an effective, out-of-the-box means to correct my mistake when most mechanics would have just written it off as a total loss. He totally saved my Jeep. Thanks Rick! I would recommend him to anyone! read more

Byron is such knowledgeable and honest mechanic. I had him complete some work on my Audi w5 that the Audi dealership recommended I take care of, except they wanted to charge me a ridiculous amount of $$ for the job. Byron, got the job done for half the price and twice the speed. A couple of weeks after that, the car broke down on my way to work and I called him in a panic. It's getting old. He said I could have it towed to his garage that morning. He diagnosed the problem ( fuel injectors drama) and had it fixed and back to me in a day. Not only did he fix the car, but he made sure to drive it around for the while to be sure the new parts were working perfectly. I sent my husband to him right after he fixed my car and he was delighted with the service too. I am incredibly grateful for his honesty, speed and his very fair prices! If you are looking for a genuine, no bullshit mechanic in Marin, look no further than Ross valley auto repair. read more

Agree that Rick is the best. Fair and never does more than is needed, but very thorough. Really knows his stuff.

Rick is the best mechanic I've ever dealt with for many years now. A very competent Jeep specialist with many years of experience. Honest and always does an A1 job at a fair price. You truly get what you pay for! I've tried other mechanics closer to my home, but regretted it in the end. read more

If you have a JEEP this is where you should go, Rick at Ross Valley 4x4 is a Jeep expert and has been for 20 years. I have been bringing my Jeep here for 4 years and each time his fairness in repair has been exceptional. I have no fear bringing my Jeep in for diagnosis as I have learned Rick will actually work to find ways to save me money on repairs. Case in point, I have a known Jeep problem with my reverse light switch. Obviously these lights are important and Rick did let me know if the switch completely dies my Jeep will not start so Rick did some research and has found away to rebuild the switch versus ordering a $ 350 part. Its saving me a lot of money. This is the car I drive my 5 year old around in and he always make sure my vehicle is in tip top shape. I refer everyone here and you owe it to yourself to have him take a look if you are considering repairs. He deserves the highest possible rating for Auto service. read more

I agree with all the other 5 star reviews that Rick has received. I've brought my Jeeps to him for over 15 years now. I hate it when I have to get a repair, or even an oil change, anywhere else! I have absolute confidence in Rick's ability to diagnose and repair any Jeep problem. He knows every model's and year's idiosyncrasies. He knows what has to be repaired before you drive another foot, and he also knows what's not worth it. If something is real expensive, he is very helpful deciding whether or not it's worth making the investment. If I were buying a new car, I would seriously consider buying a Jeep so that I could have Rick as my mechanic, even if I really wanted to get a different make of car. When I go on long trips, I know that I can call Rick if I ever have a problem, from wherever I am, and he'll have the most practical advice about what to do. If you have any sound or symptom coming from your Jeep, drop in to Rick's garage and ask what it is. Sometimes they indicate a risk to your engine or safety that you don't want to take; other times they can wait to be repaired. It is quite wonderful and so very rare to have such complete confidence in a mechanic, or any service provider. Rick is also a great person in other ways, so enjoy your conversations with him when you leave and pick up your car. The guy is a gem. David W. read more

I have been servicing my 1998 Grand Cherokke at Ross Valley 4x4 since it was brand new. I did not want to go to the dealer, and selected this garage because it was close to my work. The service from Rick Shanahan has been consistently good for the past 14 years. When there has been something wrong with my Jeep, he diagnoses the problem, tells me what the repair will cost, and completes all the work in a timely manner. He is an honest guy who has always done what he said he would do. If you are looking for an honest, reliable mechanic to service your Jeep, you cannot go wrong by choosing Rick. With his help, I plan to have my Jeep in great shape for another ten years! read more

Rick is the best mechanic I have ever had. I highly recommend him. He is honest, friendly, and really good at what he does. He worked on my jeep for several years and always offered affordable, quick and quality service. I sold my jeep, after 14 years, and bought a toyota and am really sad that Rick can't be my mechanic anymore! read more
