Herbert was a big help for me with getting my 2016 Honda accord touring fixed. I had taken it to…read moremultiple mechanics AND the dealer, and no one could tell me exactly what my issue was and just be straight with me. I had an emissions system issue that gave me the code 'P0139'. The first mechanic I took it to last year told me that it was a simple o2 sensor issue (rightfully so considering the code I was getting), yet when he replaced the sensor, the light continually came on. So he replaced it again, and replaced another o2 sensor on the vehicle (according to him). When none of that worked, he told me that my catalytic converter was faulty, and that I was going to have to pay roughly 8k for a new one. Safe to say I didn't believe him, nor did I stick around and simply take his word for it. I started making calls and, at first, genuinely believed that I was going to have to come up with the 8k by summer 2026 (when my smog inspection was due). I thought at one point I was sold a faulty vehicle too and even tried to receive compensation for the error. Turns out that wasn't the case, and even if it was, there wasn't much I could about it anymore. I took it to others who quoted me ridiculous prices for a simple diagnostic, I took it to others that just simply couldn't tell me what was wrong, and then to make things more confusing, the light would go on and off and would even go off long enough for me to pass smog!!! (Even though the first guy I went to said my catalytic converter was bad). Then, I looked online and found Master Tech. Great reviews, great location in the South Bay (Torrance), and fair pricing. Diagnostic was about 160, which would go toward repairs if needed, and if they couldn't find the issue I'd pay zero dollars! When I first got there, already Herbert pointed out things no mechanic pointed out before. I was told and under the impression that all my sensors were new and changed... they weren't. He also informed me that my vehicle was an American built one (not Japanese or Canadian, which I heard can make all the difference in quality). That's information that, although wasn't a huge concern, let me know that this guy paid attention to detail and really cared about what he was doing. He then told me to leave it with him later on in the week so he could give the vehicle TLC (tender love and care), and to be comfortable with not having my vehicle for a couple days (wasn't a problem at all). Eventually he gets back to me after a day and lets me know that the sensor had to be changed out with an oem one, as the previous mechanic put in an aftermarket one. On the day that I picked the car up and paid for the install, we both hopped in and took it for a ride, and the engine was running smooth like butter now. No more rich running (causing my gas to burn faster), and no more harsh shifting. He then hands me over the old sensor and informs me that I should go get my money back from the other mechanic. It turns out, the other guy was trying to screw me over (surprise, surprise!), whereas Herbert was honest and righteous. The piece the other mechanic put in was a Bosch sensor, made specifically for German made vehicles. Smh. It was for VOLKSWAGENS and the like ONLY. He was just trying to get me to pay him thousands, and perhaps allow me to further damage my engine and transmission from the issues he was forcing my vehicle to go thru for the time that it wasn't working properly due to a lazy, incompatible o2 sensor. I was relieved that I found Herbert who was able to help me and install the correct piece for a fair price (443 roughly, as opposed to the almost 700 dollars the dealer would've tried to charge me). I like his style, and he is definitely a righteous mechanic. Thank you bro!
