The tire air sensors stopped working within a year. Neil replaced them with no additional cost.

I genuinely thought I'd need to tow my car and deal with a full mechanic visit. But the team here was incredible - especially Colin. He talked it through with me, figured out exactly what happened, and within minutes said they would get the replacement part and fix it for me right there. This honestly saved my entire day. After finishing both the oil change and repairing the coolant pipe, they told me I only needed to pay for the oil change. AMAZING service!!! Huge thank you to Colin and the whole staff for being professional, kind, and unbelievably helpful. You guys saved my day and my weekend. If management sees this review, please give Colin and the team the recognition they truly deserve - they went above and beyond!

They checked all my lights and turn signals. Checked all my tire's pressure and added air as needed. Filled my windshield washer tank, checked my antifreeze and topped off. Then, they showed me my engine air filter and said it looked good and din't need replacing. All I can say is they were thourough, professional and couteous. All this for nearly half of what the dealer charges. Five Stars.

One of the vehicles was flipped onto its roof. There was an injured person being attended to on the shoulder of the road. So we had to slow down from the posted 65 MPH speed limit to bumper to bumper traffic. My new brakes and rotors performed extremely well. Afterwards, just prior to the descent on the I-5 into Castaic there was a big rig accident that forced Cal Trans to merge four traffic lanes to one traffic lane. A constant stop and go for 40 minutes. Finally, I was on the 126 approaching Fillmore when the upcoming traffic light changed to yellow. I was in "No Mans Land", I needed to make a split decision. Do I press down hard on the gas pedal and attempt to beat the red traffic light and risk seeing flashing blue lights from the CHP officer waiting at the intersection or do I brake and hopefully don't end up in the middle of the intersection causing an accident. I chose the latter. My new front brake pads and high performance rotors grabbed and I was able to stop behind the crossing. No skidding, no screeching tires, just a quiet smooth stop on a dime. As the CHP officer drove through the intersection, as he completed a left turn onto the Eastbound 126 he gave me a nod. A nod of approval. Then the driver to my right gave me a thumbs up. The "power stop system" you and Robert installed on my Tacoma performed exceptional! I can't express my overwhelming gratitude. I have never said this before, but I have never trusted the brakes on any of my owned vehicles more, than the ones you and Robert recently installed. Thank-you! Thank-you! Thank-you! Art

Just want to give a big shout-out to the manage, I know him as Armando, though he also goes by…read moreanother name that I can't quite recall. This young man has always been incredibly helpful to my entire family. We've been coming to this shop for quite a while, and as always, you all do a great job and keep the prices reasonable. On this particular visit, I came in to get a flat fixed on my Tacoma. The tire was still under warranty, but unfortunately it was unrepairable and no longer being offered by the manufacturer. Armando took the time to check with other stores to see if anyone still had one in stock, but had no luck. Instead of leaving it at that, he used his problem-solving skills and found the tire online from a retailer called The Rack. He ordered it, the tire arrived the very next day, and he was able to get it installed on my truck. Because of his effort, I didn't have to end up with mismatched tires on my truck. I really appreciate him going the extra mile to help me out. Thank you again!

I rarely leave negative reviews, but my experience at the Simi Valley Big Brand Tire location has…read morebeen incredibly frustrating and entirely avoidable due to repeated miscommunication and poor customer service. I have had ongoing issues with the same tire and scheduled multiple appointments specifically to have it replaced. On my first visit, the tire was patched and I was told the tear was borderline and should be replaced if it lost pressure again. When it did lose pressure weeks later, I called ahead, ordered the replacement tire under warranty, and came in expecting it to be replaced. Instead, I was talked out of it by the technician (Cesar), who told me the tire was still fine. I trusted his professional judgment--only for the tire to go completely flat again later. If it had been replaced when I asked, this entire situation would not have happened. On the most recent visit, things got worse. I called the store multiple times: - First call: disconnected - Second call: left on hold for over 6 minutes - Third call: Cesar assured me the tire could be obtained that same day I called again to confirm before leaving work and arranging a tow. Once again, Cesar reassured me the tire would be available that day. At no point did he mention that it would be a different brand tire. Based on those assurances, I left work early. After my car was towed in, I was then told the Continental tire was NOT available after all, and that only a different brand was an option--and that it might not even be safe to drive on in the rain. That crucial detail was never mentioned during either confirmation call. Management declined installing a temporary tire, and the only solution offered was a one-day rental car, which I still had to pay insurance and gas for. I was also told that the labor and warranty costs on the new tire could not be comped--despite the situation being caused entirely by misinformation from their staff. To top it off, when I returned the rental car, the store manager Juan was extremely unapproachable. The first thing he said to me was, "You filled the gas in the car, right?" No greeting, no apology, no acknowledgment of the issues his team caused. This location has serious communication and customer service problems. I am willing to try another Big Brand Tire location, but I am deeply disappointed in how the Simi Valley store handled this situation from start to finish.
