Auto Diagnostics and Repair Service in
Ridgefield (NJ)

Easily one of the most trustworthy and down to earth mechanics around! Manny had my driver side mirror replaced the next day and is looking good as new. He also did some work on my old Honda a few years back, so as a returning customer I did NOT leave disappointed yet again! I highly recommend this business for all your car repair needs!

Gotta say by far the most honest man in the auto mechanic business. Also reliable does not oversell. My mechanic actually became my friend and he is a very good person. I would recommend anybody to take their vehicle for repair to him.

Great mechanic shop! The staff was honest and professional. They explained everything clearly. My car runs perfectly now. Highly recommend!.

Absolutely stellar experience! The team at this Ridgefield auto diagnostics and repair shop helped me find something very important to me —and they did it fast, smooth, and with zero fuss. The staff was super attentive, friendly, and honestly just awesome to work with. Couldn’t recommend them more!

Always helpful, fast and very responsive. I’ve been looking for mechanic I can trust for probably 4 years. And when I brought my car to Manny I knew my search is over and I can trust him my vehicle’s safety.

Everyone is looking for a good mechanic. You'll find one at Auto Diagnostics. I have every confidence in Manny. Tells you what is wrong and there are no surprises. A+

Been bringing my car there for nearly 7 years to Manny and the guy is honest and looks after his customers and does what is best for the vehicle. Big time Honda Guru he is.

Best auto mechanic shop around, Manny and his crew know the ins and out of every problem, been coming for service for a long Time, always did me good.

Manny, is extremely knowledgeable, professional and trustworthy. He took the time to explain the repairs needed and provided honest recommendations without any unnecessary upselling. He also updated me via text and later called me to go over the details and answer any questions. Exceptional service-professional, and highly convenient!!!

I’ve been a customer for years and Manny at auto diagnostics always puts quality service first and takes care of your needs

I have a 2002 landcruiser and I have been reluctant to bringing it to anyone other than toyota. another mechanic recommended him and now myself and family members bring their cars there. he is honest and affordable.

Went in the morning because my car was making a noise through out the week. Unfortunately that morning it wasn’t making the noise haha. But the mechanic knew exactly what I was hearing after checking out my car! The first time I met this auto shop was when I bumped my front bumper he was able to get it out with a heat gun!! Super customer service definitely recommended

I have been bringing my car to Auto Diagnostics and Repair for over three years, and I can honestly say it’s the best decision I’ve ever made when it comes to auto care. Manny, the owner, is incredibly knowledgeable, honest, and professional. He takes the time to sit down with you, explain in detail any issues your car may have, and go over all possible solutions. He is always transparent about pricing and works hard to find the best options for you. Even after moving out of New Jersey, I still choose to come back here because the service is truly unmatched. The entire staff, from the front desk to the mechanics, is respectful, attentive, and welcoming. As a woman, I’ve always felt comfortable and respected here — never once have I felt misled or taken advantage of, which is something that unfortunately happens too often in this industry. Manny and his team treat every customer with honesty and respect, and they go above and beyond to make sure you leave satisfied and confident about the service your vehicle received. Finding a repair shop you can trust is rare, but Autodiagnostic Repair is exactly that — trustworthy, reliable, and professional. I highly recommend this shop to anyone looking for excellent service and peace of mind when it comes to their car.

I travel to New York City for Maryland and arrive to New Jersey with some misfires in my engine… Manny diagnosed the issues and fixed it all up and I’m very appreciative for their excellent work. I got home safely.

I’ve been going to Auto Diagnostics for about 10 years now. I would never want to have my car serviced anywhere else. Manny is very honest and trustworthy. He always diagnoses the problem quickly and makes the correct repairs every time. I have never had a problem they cannot repair, and whatever work they have done has never needed to be repaired again. Manny keeps repair prices low and I’ve been very happy with the service and results.

Had to get my rear subframe replaced and I can say the work was quality and spot on. No other shop wanted to take on this job but these guys exceeded my expectations and definitely did a A1 job. Have been back 2/3 times since and will continue to do so, my new go to shop.

I have been a customer to this business for many years, always a great satisfaction with Emmanuel and all His Staff, many of them are bilingual listening your needs and preferences for your car. Very fair prices in the area.

We’ve been taking our cars to Manny for years never had a bad experience. The quality of the work performed is consistently good and the pricing is fair. They know how to get it well done when it comes to repair and maintenance of our vehicles. Highly recommended 👍

Manny was fantastic and professional. He repaired my power steering pump on my truck. I definitely recommend Auto Diagnostics.

Manny and his team are always helpful and explain everything clearly. Their work is excellent! I would highly recommend going to Manny for all your auto repair needs

Manny and his team are the best repair shop that I’ve ever been to. There are no nonsense and at the end when they do the work, they show you the parts they took out of the car, which is phenomenal for me. Manny and his team they get the job done. Thx.

Believe me when i say this place is Excellent it really is. Been going to Auto dynastics for 7 years and I love this place Manny & his crew are professionals ..ask me. Prices are so great won't be disappointed. Just want to ad car still running 211000 miles and runs like new. All services done at auto dynastics .

When I brought my car to Manny, I left knowing that my was in good-capable hands. He fixed all of the problems my car had and went above and beyond to get the job done on time - and as busy as I am I wholeheartedly appreciate that! I'd recommend this shop to anyone whose in need of automotive repair. Be smart and get it done right. MANNY IS YOUR GUY! P.S. Staff Rosa and Lisa were great also... 😉

Replaced my rotors and pads, did brake fluid flush and oil change today. They found few issues and told me about them, providing estimates. The manager is very professional and honest. Also, he gave me a great price, which I appreciate a lot. The mechanics who worked on my car were top notch! My new car garage from now on!

I needed for a reliable Mechanic to install a Rough Country 1 1/2" lift kit and Romik running boards and Manny and the team came through. I like visiting places that pay mind to your concerns and deliver professional results. My SUV is looking great and driving great!

I'm very picky about my own car and have seen the subpar work of many local mechanics and dealerships that drove me to always do car-maintenance for myself. For the things I cannot do or when I don't have the time, I go to this shop. This shop has not let me down! I've spoken with Manny and Jose in all my times here. They are both very knowledgeable, polite, and most importantly HONEST. They've changed the brake pads and rotors on my 2008 Toyota Tacoma while charging 1/4th of what the Toyota Dealership was quoting me on the phone. Did a great job on it too, Most recently I took my 2013 Lexus GS 350 to get the Transmission Filter and oil changed, brake-fluid flushed, and the front wheels aligned. Manny said all the right things when explaining what he would do. Other shops were kinda clueless when describing their process. I shopped around for prices and they were very fair in the work they've done for me. As for the recent maintenance work, the car is now shifting smoother and the brakes are not spongy (they didn't get air in the system which is good). The car rides straight on flat road so the alignment was also well done. I'm very happy with these guys and will keep coming as long they keep the Good and Honest Work up!
