The team is professional, knowledgeable, and genuinely cares about doing things right. They didn't try to upsell me or rush through the process. The communication was clear, respectful, and confident. Every question I had was answered with transparency and a sense of pride in their work. I appreciate the value in staying inside of my car as well. Pricing is competitive given that it's a turn key service, and came with a complimentary water. The shop itself is spotless. That alone tells you what kind of operation they run. Everything from start to finish was efficient and smooth. I don't often leave reviews, but this experience was too solid not to acknowledge. I'll only be bringing my vehicle here from now on.

I called this shop and spoke with customer service for 3 hours just for them to say they couldn't Do anything about it, because the person who checked my car said it was full, although it was still completely empty. It was a sorry waste of time, and potentially damaged my new car. I would never bring my car here even if I was desperate. You're better off doing your own oil change.

As a female, I know how I have been scammed by mechanics. So I found true value in Christian Brothers Automotive-Peoria, Lake Pleasant Pkwy!

Tom, and the entire staff served with a smile. Overall, I would highly recommend this Christian Brother Automotive to anyone. We'll stick with them!

I've had the same mechanic for about 30 years (a family owned & operated shop in WA), and the thought of going somewhere else petrified me. I really needed an oil change and tire rotation and chose Grease Monkey on Bell based on Google & Yelp reviews. I was greeted right away, explained what my needs were, and Thad did his best to reassure me that I would be well taken care of, they would show me all parts before replacing, and would not try to upsell me. He also said they have bays in back with mechanics to do other work when I need it. I did need a few other things (rear brake light, wiper blades, cabin filter) and each time someone came in to get my approval. I had no idea my wiper blades would shred in the heat! If it's raining, I'm more likely to be standing outside letting it hit me in the face than going for a drive. They were very patient in getting me every discount they could. Coupon codes from the website AND a senior discount! In and out in less than an hour, including wait time to get my car in the bay. The website did mention a carwash, which they don't have at this location, but that was not a deal breaker at all. I highly recommend this location and will definitely go back when I need anything else done.

When I brought it back to address the hazard, Dan refused to take accountability. He flat-out lied that nothing was loose and spoke down to me with blatant, condescending sexism, assuming I knew nothing about cars. I hold a degree in automotive engineering; the only reason my vehicle was in their garage was a temporary lack of tools, not a lack of technical knowledge. Miraculously, after the "inspection" where they insisted nothing was wrong, the car suddenly drives completely fine. They fixed their dangerous mistake behind my back while actively trying to make me look stupid to cover up their own negligence. Dismissing a critical safety issue and treating customers with patronizing disrespect is entirely unacceptable. Unprofessional, dishonest, and incompetent.

Well, I'd like to see those records. They're not accurate. I was in church at 10 am, went home for lunch afterwards and arrived at Big O after lunch at 1:00 pm. In reading other owner responses to customer complaints I've noticed that Big O rarely accepts responsibility for a poor experience. Its always the customer's fault. That's a big red flag. ****** Big O pet-peeved me. Nice website with a place to enter information and make an appointment for an oil change, with the option to wait for vehicle. When I get there, I'm informed that I'd need to leave the vehicle...there are 5 ahead of me. Why bother taking an appointment, giving the option of waiting for it and then being treated like a walk-in? Scratch Big O off my list.

Kirk, the service manager, has been a big part of why I keep coming back -- he's down-to-earth, knowledgeable, and easy to talk to even when I don't fully understand the technical side of things. I really appreciate their communication process, including texted reports and photos of the work being done. So far, everything they've done has been straightforward and honest. When I've questioned their diagnostics or recommendations, Kirk has taken the time to explain things clearly and has even reached out to Jasper (the company that rebuilt my engine) just to help put my mind at ease. That level of follow-through means a lot, especially after a bad experience elsewhere. My one significant complaint is their shop fees. These charges aren't itemized as a "shop supply fee" or anything specific -- they just appear as a flat fee, and they're not disclosed anywhere in the initial quote. Most shops I've dealt with cap this type of fee around $50, but I was charged $90 on one occasion. Not listing this upfront feels misleading, and I think it's something customers should be made aware of before authorizing work. That said, trust in the actual mechanical work matters a lot to me, and this shop has earned that trust. I'll continue bringing my vehicle here, but I'd strongly encourage them to be more transparent about these fees upfront -- it would go a long way toward making an already good experience a great one.
