    I came into Christian Brothers Automotive on Town Center with some pretty serious engine trouble,…read moreand the team there took great care of me from start to finish. Will helped me every step of the way--he was knowledgeable, transparent, and took the time to explain my options so I felt comfortable with the decision. I ended up not going with the full engine swap, but the entire process was handled professionally and efficiently. The communication throughout everything was excellent, and I really appreciated how helpful and honest Will was. Overall, I'm very pleased with the service and the experience. I'll definitely be coming back to Christian Brothers Automotive for any future automotive needs. Highly recommend! -Shaffer

    I brought my car in for a stalling issue. The initial diagnosis cost $775 to replace a battery…read morecable and add a ground screw, which felt very high. Afterward, I was told the car had multiple oil and coolant leaks and was quoted an additional $3,500 for repairs. On a car worth about $4,000, this didn't make financial sense. When I declined the extensive repairs, there was no discussion of smaller, interim solutions or things I could try myself; the only suggestion was financing the full amount. The immediate next step was being asked to retrieve my vehicle. The shop was extremely busy, and I left with the impression that they prioritize large, high-cost jobs. Disappointed with the experience and lack of flexible solutions, I will not be returning. Update to my previous review: It's been two weeks since I picked up my vehicle, and I have not observed any oil on my driveway. This seems inconsistent with what I was told about the severity of the oil leak issue during my visit. I have checked the oil level multiple times and it appears to remain at the same level. After posting my initial review, I received several phone calls from the shop owner requesting that I modify my review. I eventually asked that these calls stop. Service details: I paid $180 for initial diagnostics, during which I was told there was an 80% probability that the problem was my battery cables. I then paid $235.19 for new battery cables, but it did not resolve the issue. A subsequent diagnosis costing $359.98 identified a bad ground wire, which was then repaired by tapping in a new wire. Additional observations from my service experience: When I collected my vehicle, I noticed what appeared to be a black, grease-like substance on the exterior door handle that was not present when I dropped it off. I also discovered that the front emblem was no longer attached to my vehicle. When I inquired about this inside the shop, staff located the emblem and handed it to me and told me it fell off when they closed the hood. I check my fluids every month, this has never happened to me. There was no offer to repair the damage.

    I had taken my car to another local mechanic to diagnose a problem with the air conditioner. They…read moremechanic said that a house needed to be replaced, but they were not able to do it because they do not have the equipment needed to evacuate the existing refrigerant 1234yf. They referred us to the Kia dealer, which I knew would be very expensive. So I did some research online and found Franklynn Automotive. I called and described the situation to Steve. He said they likely can handle it, but would start with a complimentary second opinion. After their inspection, they determined that the hose does not need to be replaced and we only needed to refresh the refrigerant, which they do have the equipment for. In addition, the reason the other shop might have suggested the hose replacement was because of a leak related to the axel. All in, the repairs would be substantially less than the dealer quote for work that may not have been needed in the first place. Overall, great experience with Franklynn.

    Went here to get suspension work done on my Tesla. Overall the vibe was friendly and the mechanic…read morethey had look at my car seemed to be top notch. He was the reason I wanted to get the suspension serviced here as his explanation of what I needed done showed his mastery of his craft. However after taking the car to Tesla to get a 2nd opinion I discovered that this shop (not the tech) was trying to charge me literally a 200% markup on the parts to do the repair. Crazy right!!! The genuine Tesla parts for the repair were $209 and these guys quoted those same parts out to $614 (I sent him the estimate from Tesla with the exact cost of the parts). Unfortunately for me Tesla wouldn't work on the car because of an aftermarket body kit the previous owner had installed. I really liked the mechanic at this shop, so I went back to this shop with the intention to move forward even though their cost was literally 56% more ($1,635 vs $2,555) then Tesla for the same work (because of the price gouging on the parts). Then when I asked about it before my approval to move forward the manager got snarky and said how would you expect us to stay in business if we don't markup the parts. I said and I quote "I get a markup on the parts and your high hourly rate for the labor on the work but not a 200% markup on the parts." The guy gave an excuse about the software they use but was unwilling to budge on the price gouging. I literally said why don't you let me buy the parts directly from Tesla and you can still mark them up 25% and he still said no. I was completely professional throughout the conversation, but obviously would not pay a 200% markup on parts on top of the already top of market labor they charge. After the conversation he texted me back and we agreed to not move forward. I only leave this review to warn others. It's a bad business practice to over charge people like that and so I just wanted to give people my story warning them to watch out and be careful before doing any work here. Update: this slime ball's disclosure of all the information I gave his manager, Steve, in good faith is abhorrent. Everything he mentioned on the car was told to them right up front as I told it to the manager, Steve, in person and this clown is repeating word for word what I told his manager. I was cool with this at first but this guy is a complete scum bag now using my own words and lying about it. Anyways besides being a scum bag, no effort at all was made regarding the parts and this shops 200% markup. I literally told the guy running the shop I would buy the parts myself and let them mark it up 25% and still the answer was a quick no. Everything I said was honest and accurate and don't appreciate this guy claiming transparency when his long shpeel was essentially just a my own words complaining about the car I bought and his shops poor excuse for price gauging. They could have done the job without gauging me on the price given I had the option to buy the parts myself. Not cool at all the response from this guy and his piss poor excuse for attempting to rip me off.

We had some extensive work done and Bob took his time to explain everything to me so I could understand what needed to be done and why. He wanted us to bring the truck back in the day after to check everything out before we left on our trip. Great experience from start to finish. Will definitely come back for any vehicle service needs.

    We took our car to Raceway Lube and spent $2,000 for some fixes…read more We brought the car home and a few days later the check engine light came on and there was a lot of brown fluid leaking. This was a brand new issue. There is no doubt Raceway Lube caused this. We took the car back, told them what happened, and left it for them to look at and fix what they broke. When we went in to pick it up, we were presented with a laundry list of things to fix. The leaking transmission fluid was nestled in the middle of a bunch of line items. Why? The reason we brought it in was the transmission leak and check engine light. We told them this when we dropped it off. Not ten other things. Then the employee said he had no idea we brought the car in last week, no idea Raceway Lube worked on it already, no idea they'd already run the codes and created a list of things to fix. The actual issue of them causing a fluid leak was not addressed at all. Incredibly frustrating. Very upset they refused to address the problem they caused, inadvertently or on purpose, and take responsibility for fixing it properly. We just took the car home. So disappointing.

    I came into Service Street - Highlands Ranch for an oil change and tire rotation. I also mentioned…read morethat the display on my dashboard was showing low air in my right-front tire. The sensor was reading 28 psi. While travelling to Yellowstone National Park, this light came on, and I pulled over and checked for a nail (I didn't find any). I stopped at the nearest gas station to check the air in that tire and it was fine. I put a little more air in that tire just to be sure. The gauge read 40 psi+, the dash displayed 28 psi (and did not change). What I realized later was that I put air in a tire that did not need it and overinflated to approximately 40 psi. When I arrived back in town from our vacation, I instructed the technicians to check all the tires and have them all inflated to 35 psi (Per the manufacturer's recommendation). When I picked up my truck, the low tire pressure light was off, but now ALL the tires were reading 46-47 psi! I asked the tech about this and he said, "Yeah, when you brought it in, all of the tires were really low - the highest one had 17 psi. So, I inflated all the tires to 35 psi, as instructed." When asked why the display on my dash said 46 - 47 psi, he shrugged and said something to the effect that sometimes the sensors are off a little. I questioned why they would be "off" by 10+ psi. So, the next day, I took the truck to the Discount Tire next door and had them double-check the air pressure. Just as I suspected, ALL of the tires were OVER-INFLATED to 46 psi! As the tires were being deflated by the technician at Discount Tire, the sensor for the first tire did not match the tire being deflated. According to Google, " TPMS sensors need to be reset (relearned) on GMC trucks after a tire rotation to ensure the vehicle correctly identifies the new location of each tire. This prevents the driver information center from displaying wrong tire pressures for specific positions. The process is often called a "TPMS Relearn." This process was not done at Service Street. If a technician can't do something as simple as inflate a tire to the proper tire pressure, how can they be trusted to do something more technical? This company has lost my business. P.S. I want my money back for the other pre-paid oil changes. I'll take my business elsewhere.

    Guys.....what's going on??? Why the excessive staff…read moreturnover? Hugely disappointed in getting communication from shop on when car would be ready. "It's not my job" attitude because one of your associates wasn't my service advisor, so if I don't call to inquire on car status then my car would still be sitting at shop while I'm home without a car. For the 2nd time car is returned with soiled / dirty driver seat and inside door panel / armrest. I feel training in customer service is lacking along with taking pride in the work you perform. The issues were fixed (I'm hoping), but vehicle now has a blinking light that wasn't there before.
