The service was completed both professionally and quickly. The staff members were very knowledgeable and courteous throughout my visit. In particular, I would like to commend William, along with the other service members, for providing such a great service experience. I will highly recommend the Thornton location to others for their vehicle oil change and maintenance needs. Thanks again to William and the team!

Went in not even a month ago. I scheduled an alignment, balance and tire rotation. I waited 3 hours…read moreand all they did was "align" my car. I was already upset that they didn't do everything I asked in a span of 3 hours I waited. considering I scheduled an appointment 2 days prior. 2 weeks go by and my car is squeaky and it's bad, even worse as I reverse so I find a local mechanic. I couldn't deal with the noise for 1 day. Thankfully, this guy knows what he is actually looking at!! First thing my mechanic told me was my tire was SHAKING.... mind you I am a single mother, I drive my car with MY 3 YEAR OLD. That is DANGEROUS. Have I waited, it could've ended up FATAL. Second thing is I have to get my car REALIGNED due to Les Schwab not doing their job right the first time. I spent about $200 for a job they couldn't even do. THANKS for the additional problems and payments ... this was so inconvenient and I would NEVER return to any Les Schwab location again. Be considerate and start ACTUALLY DOING SAFETY CHECKS..

Been Yelping for a while I never want to leave a review such as this but I felt compelled to let…read morepeople know my experience. I had scheduled to go to my normal mechanic but had reasons to need to get an oil change sooner than they can get me in, my partner has been coming to this grease monkey and hadn't had issues so I THOUGHT I could trust his experience. They got me in and out in 15 mins on a Wednesday mid morning and I drove away feeling great, happy I got something checked off of my "to do" before hosting guests in town. Until I found a pool of grease in my drive way after getting home from some errands. When I left their office they said everything checked out great, they recommended transmission fluid change that I declined as I want to do that w my mechanic.... and there were no issues when I was paying. They failed to tell me that they found a leaky drain plug before they performed the oil change. Did not call attention to it during the process or when I signed, said everything checked out fine, took my money, which was about $80 after coupon and tax for the house synthetic..... Yes, I should have read the paper before signing... I also should have been notified that they found issues, before they decided to swap out my oil. In looking at the reviews, they probably damaged my drain plug during their speedy process, put a note on my receipt and got me out in a jiffy. The really trippy part, was when I took it back that same day in the afternoon, asked them kindly on how they can help me, that I was not notified of the issue before the oil change. I was told - that's our cashier's fault for not telling you, nothing we can do. The messenger asked me who helped me as the cashier and said let me check with my manager on what we can do... The manager did not come out to address, hiding in the bay below deck, spoke through the rep - the messenger only said that since the note is on the receipt and I signed, they are not liable for anything and I'm out of luck - though I can take my car to Big O's down the street and they might be able to give me a good discount as they are partners. They were able to tighten the screw more so it's leaking less - my problem was that my car was not leaking before I got there. The worst part, is the person I was speaking to said that they are not real mechanics and do not have the tools to help me. I then asked if there is anything they can do to address the lack of responsibility potentially with something on my payment due to their cashier not informing me of the issue. It couldn't have been done. I called my normal mechanic right away and they were going to help me but I'm nervous that GM had done more damage to my vehicle in order to partner with another business for additional gains. I am glad this is a lesson I learned the hard way... would recommend anyone to go ahead and skip this location. Especially now I've read reviews on Yelp w other female customers. I was a first time customer here and this would also be the last time. Just hope my mechanic would be able to fix the issue quickly and easily. PLEASE PLEASE PLEASE, do yourself a favor and skip this inexperienced location before they damage your car further. Off my soap box.

Most recently, these guys had my car for over 2 weeks for a noise I was hearing. First they misdiagnosed it. Then they told me it was the transmission and had the car torn apart. Then they had no mechanic in the shop at all for a few days. Then they hired someone who said the noise was the rear struts, fixed those, but left the battery dead. During all of this time, they never called me one time with an update. Not once. They didn't tell me the misdiagnosis until way after. They didn't ask me if they could tear the car apart. They didn't tell me they had no mechanic to put it back together. I had to call myself and pester them to find out what was going on. Worse yet, the noise came back less than 2 weeks later.
