Dishonest Owners…read more Failed smog check cuz the check engine light indicated a sensor issue, and it had something to do with emission control system. Panicked so i went here for Diagnostic, one of the Brothers said it's the Transmission, needed a new Transmission or Rebuilt Transmission. Went home puzzled and confused, so i did my own research and scanned with my own OBDII device, it reads bad sensor... Ordered the Sensor, costs $50 off Amazon and car runs new again.. Was puzzled and confused coz i had cars with bad/slipping transmissions before and i was aware of the symptoms it caused. it's metal gears, so "if" it's a Transmission it will continue to Slip until it's Dead. Coz it's metal gears issues doesn't come and go, it gradually gets worse and dies within a week or two..., not acting intermittently. That was the reason i knew it wasn't the Transmission.. This Place is Dishonest, the Owners/Brothers are Dishonest, and i'm also a Firm Believer the Employees are a reflection of their Management, but "if" y'all are born with $$$ and ignorant/naive then maybe this place is the right place for y'all.. He was going to Charge me the price of a Transmission and turn around and sell my Good Transmission to unsuspecting Someone Else.... in Reality, ALL He had to do was change my Sensor($50) and charge me a Few Thousands.... Dishonest crooks, thieves, liars, unethical, no morals, cheating deceiving pos, etc....... "if" i can rate "0" stars i would, Yelp is being very Generous for Shady Businesses...... Honesty n Reputation is the Best Policy

I would give Tom, the owner, 10 stars if I could. A relative referred me to Rosemead Auto Repair…read morefor a soft brake issue, and I'm extremely grateful they did. Tom was honest, professional, and efficient from start to finish. He initially quoted me for replacing two parts, but when the issue was not fully resolved to his standards, he replaced several additional brake components at no extra charge. That level of integrity and dedication is hard to find. My brakes now feel strong and responsive, and I'm very pleased with the results. It's reassuring to find a mechanic I can truly trust with the safety and performance of my car. Tom does outstanding work, and I highly recommend Rosemead Auto Repair.

Basically there's no difference between Honda and Toyota oil. He said for $61 I can have the Toyota oil with a Honda oil filter. Or $55 for a synthetic blend oil that he uses for Nissan, Mazda and Kia cars. To me oil is oil, he said I can go to Walmart and get the oil I want and he can do the change for me. Why hassle it? I went with the Toyota oil. He checks tire pressure and top off other fluids in the car as well.

Was recommended by a friend to use Cornerstone and was not disappointed at all. Originally I had…read moreplanned to take my car into their shop but due to my busy schedule they were able to make a mobile repair instead and came to my house. Danny and Fernando were my mechanics and they both arrived on time which is a great first impression. Danny and Fernando were friendly and very knowledgeable in their craft. All around great guys and gets the job done. I was told how long the repair job would take and left them alone to work on the car and headed back inside my house. Once everything was done, Danny gave me a call, emailed and texted me my invoice, handed me my keys and everything was done ahead of schedule. Honestly one of the best auto repair/mechanic experiences I have ever had. Pricing was fair and Danny was honest about everything, price, what was needed, what was not needed. It is very hard to find a good honest mechanic so if you are in need of one, I HIGHLY recommend Danny and Fernando of Cornerstone Mechanics. You will not be disappointed.

He seemed to really be interested in seeing what the issue is before giving me a quote where as other mechanics just gave a flat price/quote without any further detail or even a "Hello". When I came into the shop, Ohan and another old gentleman in the front assisted me. Their service was amazing. They gave me a quote after looking into what the real issue was and it did not feel like a pushy mechanic looking for a quick buck. After dropping off my car, they called me a few hours later letting me know that the car part required already arrived at the store and my car would be ready soon. I was expecting to leave my car for the night however they took care of it in less than 4 hours (even with a busy garage). I would recommend this mechanic for their amazing customer service and fair price.

Beware! Very Shady! Incompetent! Unprofessional!…read more Disrespectful! No Customer Service Care! No apology! Do not come here! I absolutely will sue them at the Pasadena Courthouse! Visited today 3/17/2026, after speaking with Matt the day before. I brought in brand new 21 inch Tesla rear wheels and Michelin PS4 tires for installation on my car. I drove over an hour from Chatsworth, California to this location so that they could use the Hunter Revolution machine, specifically to avoid damaging my wheels. Nevertheless, Matt, if it's his real name, severely damaged my new wheel near the wheel center cap area with the machine that was made to avoid this. How incompetent!!! He lied to my face and gave dull, illogical, dummy excuses about what happened. Bottom line: He damaged the wheel and would not acknowledge and take accountability for his actions. I had to call the police to make a record of this issue because I will be suing. The damage was caused because he did not apply the machine's plastic adapter when he clamped onto the face of the wheel; he clamped to the face of the wheel with metal to metal contact and severely damaged the paint. Sorry, nothing can improve ignorant people! See videos and photos.
