I was having issues with my Chevy Trax not shifting properly. A friend recommended taking it to BG Automotive and they didn't disappoint. I spoke with Jesse. He was helpful and accommodating with helping me get my car repaired. They were able to get me in on short notice and within a day they diagnosed and fixed the problem. I'm so grateful for Jesse and the technicians there. They got me back on the road ASAP. Thanks guys. I appreciate the help.

BG Automotive? More like "BS" Automotive. The one star is for an oil change (since 0 stars is not…read morean option). BG Auto IS SHADY, smooth talking for sure, but A RIP OFF. STAY AWAY. This is a lengthy description, but it's not half the story. To all the glowing 5 star reviewers - check your invoices. The problem started with their "courtesy inspection" accompanying the oil change, where half of their recommendations (deemed red flag "Requires Immediate Attention") ultimately turned out to be mostly unnecessary and absurdly expensive. That became apparent only after paying. My bad, of course, I obviously should have asked to see a detailed estimate prior to the work. The initial estimate did not provide parts or labor detail & appeared to indicate the work was part of a "complete tune up." Upon dropping off the truck, "Service Advisor"Jesse stated that Champion copper spark plugs had been factory installed on 2013 RAM 2500s, so that was best & what BG would install. Classic BAIT & SWITCH: BG charged $508.48 for a set of 16 plugs! When I challenged the bill, asking if "kryptonite plugs" were installed instead, Jesse indicated, no, the copper plugs were used... then he checked his computer & stated, actually no, in fact the [far] more expensive NKG iridium plugs were installed. "They're much better because they last up to 100,000 miles," he emphasized. I replied, "Great. BG just changed out NGK iridium plugs that had been in the engine already, with only 60,000 miles on them." The WORK WAS COMPLETELY UNNECESSARY. Also on the bill was a "TOTAL FEES" charge of $175.77 (yes, that specific), but with ZERO DETAIL of what those fees were for or how they were calculated. Jesse couldn't provide that detail either, "It could be shop supplies, or hazardous disposal - you know, those state regulations - it could be almost anything." Note there were no hazardous materials involved with this work, such as a tire or battery disposal fee. (Google search indicates: In Colorado, shop fees are usually calculated as a percentage of the labor cost (e.g., 5-10%) and are often capped at a maximum amount (e.g., $25 to $50). Also, Colorado statute requires the repair invoice to have some kind of description of these fees, and further, "a description of each part by name and identifying number." Nowhere on the invoice was the type of plugs installed specified, either. You get NADA DETAIL from BS Automotive. Finally, while repair shops typically mark up parts 70-100% of wholesale price, BG is marking up parts in the ballpark of 100% of retail price. (If you can pry out of them the parts brand they say they'll use, you can easily verify this with a Google search at their counter.) They should be ashamed and embarrassed for what they're charging the hardworking folks of Longmont. When pressed to justify the charges, Jesse insisted they were competitive, "within 5% of other local repair shops." More BS. Comparing apples to apples (parts & labor only), the local dealership quoted over $200 less, the Loveland repair shop I've frequented in the past was over $400 less (obviously, checked after the fact...). If the handful of other shops Jesse quoted are actually within 5%, they are ripping us off too. Jesse would not budge on the final bill, but he did offer to comp me an oil change. As if! I had already told him I would never set foot in BG Automotive again. However, I would take a call from the BG Automotive (Owner) to provide the rest of the story about this pathetic BG encounter.

I really liked him, appreciated his work. I hired him to…read morereplace the power steering pump, the cost was absolutely cheaper than other places especially because I bought the part my own. After the work done, the car felt pretty much same or sometimes even worse, for example the handle gets really stiff to turn. He says that it's very normal process because the air has to be bleed out. Weeks have passed with same issue so he came to check the car again and said there's power steering pump rack problem. The rack is usually $1000-2000. Personally didn't really think it would be the rack problem with several reasons and decided to take the car to bigger auto shop. After diagnosis, I was told that the power steering pump is failed because when it was replaced, the flush should've be done but since he skipped it, now debris in fluid damaged not only the whole new pump but also hose and reservoir. Of course as car owner, I was definitely frustrated with the fact that now I have to pay extra more money than before when I thought I could save money because of how mechanic guy has done. I personally had to pay new power steering pump+labor fee but now I have to pay another new power steering pump+hose+reservoir+another labor fee. I will accept the fact that I was asking money back at first because.... who wouldn't? It might not be making sense to ask money back for damaging the new power steering pump by how poorly worked done but I thought the labor fee at least would've been made sense. Instead of taking accountability, he would be defend and saying the book he learned from says that power steering pump replacement is totally okay without the flush and had no problem with all other cars or sending me the google search screenshots. Of course the warranty wouldn't cover anything of things even if he damaged the new part and extra parts of car. Currently I wanted to see more opinions than one or two so took the car to another new auto shop, they also agreed that power steering pump is failed and with high possibility from how it was worked done. Surprisingly the rack itself doesn't look like having a problem, different than what this guy said. People at auto shop also say that flush is very necessary for the pump replacement, especially when the car is old. As I personally said to him, people can always make mistakes but important thing is how to handle. I got an apology eventually. But I wasted money. The other thing, he advised me to replace rear break pads soon. I went to check the break pad recently, all my break pads are not needed to replace due to adequate thickness. I would say he is a capable man to do some works on cars but I can't say he would be with more complicated jobs.

They reported that the A/F sensor is faulty/needs replacement. I have since requested a full refund for that service since they installed a faulty A/F sensor and have not received that as per contract.. To say that this mechanic has screwed me over is an understatement. Do NOT waste your time or your money here! Originally I had Sage quote me for a torque converter replacement for $1020.43. I got a phone call later letting me know that I needed a transmission replacement instead. He told me the labor would cost the same since the car was already taken apart and we would discuss where to get the transmission. I was given two options; $1500 used transmission with about 30k in miles or a remanned transmission for $3000 with warranty. I was highly advised to get the remanned transmission because it would have a warranty in case any issues were to arise. And I'm so glad I did because the transmission company from CA refunded me in full after sending me a faulty transmission then the nightmare began. Sage Automotive was extremely unprofessional and bit off more than they could chew. If you look at their available services here on yelp, transmission replacement is not listed. Sage could've easily done the right thing and said, "Hey, you're going to need a new transmission. I don't have the necessary skill set to do that let me refer you to ..." but no, I was reassured about the service and that it would not take more than two weeks. My car was held hostage for almost two months. I was given the run around every time I would ask for an update and treated as if this was a project car when this is my primary source of transportation. The job got pushed back multiple times for different reasons; technicians getting sick, wife's birthday, food poisoning, etc. I would understand if this was a favor that I asked from a friend but I'm literally paying for a service and was neglected as a paying customer. I paid for the transmission along with the labor in FULL before the service was even completed!!! So why prolong the process when you have been paid? I dropped the car off Dec. 26th 2025. Thursday Jan 7th the transmission was delivered and January 12th the transmission job was supposed to be done. I had a trip planned and was hoping I would have my car before January 13th. Come Tuesday Jan. 13th I have my flight out of town and I was given no phone call, text or email update on my car. I had to reach out to Sage myself 2 days after the agreed due date to make sure that I would receive my car when I got back that Saturday. I was told by Sage that my car would be ready by then, but to my surprise I had received a phone call while on vacation only to be let down yet again and that they would need a couple more days. On this phone call I was not given a due date for my vehicle, "... I don't want to put a due date on it because it seems that every time we do it gets pushed back." Also " I spent $400 on tools for this job.." Why is this relevant to me? Normally that wouldn't fly at other shops. Why couldn't Sage do the right thing and be transparent that he COULDN'T HANDLE THE JOB. I was also told that I would be reimbursed for a car rental (no amount or type of car was specified on said phone call). I went through Costco because it was the cheapest option and was billed $196.18. My total was a lot more due to insurance fees but I ate the cost of those. I had no say in the type of car I was given, I rented it for 4 days to get me through the weekend and to my early shifts that week. I only asked Sage to cover the $196.18. After sending Sage the bill I was met with a passive aggressive email written by AI that said they would only cover up to $150 for a 3 day rental and criticized the choice of vehicle because I should've chosen something of "equal value" to my car. Using AI to write a business email seems really counterintuitive to just reaching out and asking more questions about the rental costs instead of making assumptions. They also requested email to be the only form of contact moving forward to save their ass from making more commitments they couldn't follow through with. I paid $1251.05 for the job and was told that the new transmission was faulty. Sage reached out to the company in CA and they were able to send a new part replacement and cover the labor cost for the part replacement. Outstanding service from those guys. The part arrived Monday Feb. 2nd and I reached out that I would need my car no later than Tuesday Feb. 3rd. Let me preface that the valve body part replacement is a simple quick job for someone that knows what they're doing (2hrs).

The office manager took one look at the data plate and refused to verify the VIN (which also had supporting paperwork), insisting that "it's not a VIN" and that I needed to have the highway patrol issue a VIN. This was said with some hostility, as if I was trying to get away with something or make her an accomplice to a crime. So I went across town to Air Care Colorado, which cost me extra time and money, and there they didn't even blink, they just did the verification, and I now have the title to the trailer with the totally-legitimate 6-digit VIN.
