Our car was repaired and we were back on the road in little time. We are so appreciative of the excellent customer service and care of our vehicle. Thank you!

I really don't like leaving bad reviews, but I've given this company multiple chances to make…read morethings right and a lot of time to respond--and now I'm left with no choice. They installed brake hardware incorrectly, and after bringing it to their attention, I gave them several opportunities to fix the issue. Despite that, I've received no response at this point. Another mechanic, who I called for an unrelated issue, noticed the poor brake installation right away and recommended I get the original shop back out to correct it--which still hasn't happened. To make matters worse, the guide pins and other metal-to-metal contact points were not greased properly with fresh grease, which is basic brake service 101. It's incredibly frustrating to pay for work that isn't done right, especially when the company won't stand behind it. I hope they take this seriously and improve how they handle both service and communication.

Caveat emptor! What you're "quoted" at RNJ Automotive and what you are ultimately charged may be…read moretwo *very* different amounts. Never had as many problems just trying to get a reasonably accurate estimate from any auto repair shop as this one. The process with four other shops I checked out for the same repairs using same description went smoothly, so not sure why it was so difficult for RNJ. Needed a simple headlight replacement, installation of a new combo meter (circuit board that displays speedometer and odometer), and a quote for an engine swap on a Prius. The woman who provided a two hour quote for the combo meter, Nancy J., didn't know what one was - which is understandable - but apparently couldn't be bothered to look it up. On July 15 promised to get me a quote on the engine swap the next day, then almost two weeks later (July 27) said still didn't have it. Rather than being somewhat apologetic for not following up as promised, her reply was seething with sarcasm. Things rarely turn out well, in my experience, when a company is this careless and puts someone who doesn't understand the fundamentals of customer service as your first point of contact. It's not uncommon for these companies to exercise poor judgment in other aspects of the business as well. Bottom line: Service leaves much to be desired and prices not very competitive. Too many shops out there who are eager to earn your business and extremely capable to put up with this level of carelessness and sarcasm. Is this shop better than a dealership as mentioned in several of the positive reviews? Sure. But that's setting the bar really low. [Note: Nancy edited her sarcastic comments out of the allegedly entire conversation in her response. Can't help but think if they're incapable of honesty in a review, how much can you trust them with your auto repairs?]

On Feb 22, 2026, I made an appointment online for the next day, for an alignment and for tire…read morerotation, which was confirmed by email. Nobody contacted me before my appointment the next day at 11 am to tell me they were having problems with their machines. When I walked in, M told me that a machine had problems and they could not do the tire rotation. She could have called me or emailed me the day before or anytime before 11am to let me know, to give me the option of canceling, which I would have. Since I was already there I told her to do the alignment and she agreed I could return later for the free tire rotation. Then AFTER the "alignment" was completed, she stated that they couldn't do a complete alignment because one of the four adjustments had to be done a the dealer. She showed me the sheet of the items completed, and the ones which were not. It seems to me that they would known, or could look up the model, in advance, which adjustment required a dealer to complete since this is an ALIGNMENT shop. As I left the shop I could tell immediately that the van shuddered far WORSE after the partial alignment, especially when I braked !!! The steering wheel jiggled even when going straight. So I had paid $150 and the van drives much worse. So now I have to go to a dealer, and pay for a complete alignment and tire rotation. Not to mention the time I wasted. A few days later I took it to Rick Hendrick and had the van tires rotated and aligned. They charged me about $160.00. It drives much smoother. Certainly if I knew it wouldn't be getting a complete alignment at Mavis, I would never have agreed to it. Its like agreeing to a partial appendectomy. It doesn't solve the problem. I paid $150 and for that I got an incomplete alignment and no tire rotation. I feel ripped off and feel I deserve a full refund. I did contact them and never got a response.

I pulled in because I sometimes have issues reading my dipstick for my oil that's round instead of…read moreflat. So I pull in and Aurora the store manager take a look at my oil level level because I wanted to get a second opinion before I just added oil and added too much and of course, my oil was low extremely low and she helped me Get it back to normal, which that is not something they normally do but right now I'm struggling I need for brand new tires I mean heck at this point I would take even worn out tires cause mine are beyond worn out, but I'm homeless and I'm door dashing as much as possible and I just haven't been able to get ahead to be able to get tires and I just cashed out of my DoorDash just to put enough gas in my car which left me three dollars in my account which is not enough to buy a quart of oil so she truly helped me out with a quart of oil Top in my oil often getting it back to normal so I don't blow up my car and I am so thankful that she extended the extra care and concern to help me. It means a lot there aren't people out there who do care and I guess I need needed that Today because I've been discouraged about the other bills that I have to pay so she truly helped me out so much I get the store and Location five stars all the way across the board they didn't have to do that but she did and it means a lot to me and she knows a little bit about preventive care too so it's kind of good to have another girl know a little bit about cars Because I've been struggling with mine ever since my dad passed away a year ago so Aurora if you're reading this, thank you so much you made my day you save my car and I definitely will be back. Mavis tires should not lose you ever they need to keep you on board and clone you and send you out to the Decatur locations which is not so great over there. The Mavis in Decatur tried to get over on me and I felt coming here that was not any bit of any intention of trying to get over on me so when I do have to get tires, I will be coming to Mavis here on marathon Way. Thanks Aurora. You're super.!!!

I am a professional mechanic with 40+ years of experience. I run a very busy company and recently…read moreallowed Automotive Dynamics in Woodstock GA to work on my truck because I am simply too busy to work on my own vehicles any more. The sensor in my fuel tank that runs my fuel level gauge was malfunctioning and needed to be replaced. I made an appointment which required me to wait two weeks into the future. I took my truck in on a Monday and it was promised back by Wednesday. Wednesday afternoon, the owner Matt Braden called me and said he had not worked on my truck because "other work had come in". This was the first insult... why did I make an appointment only to be pushed aside for other work? Matt said he had to remove the fuel tank from my truck to change the pump/sensor assembly. He went on about how hard it was going to be because it was half full of fuel. We calculated the weight of the fuel while on the phone and it was only about 150lbs. With a lift and a transmission jack, this is nothing and very simple to do. There are only 4 bolts and a few hose clamps holding the fuel tank up into the truck. I told him I could wait one more day and he said he would work on it. When I went to pick up the truck, the bill was $755!!! I was SHOCKED. He charged me 4 hours of labor to change the pump/sensor and 1 hour to adjust my parking brake. The parking brake adjustment takes less time than it takes to put air in a tire. I had no idea he was going to charge me more than a few dollars for this. I went to drive off, very upset, and then put the parking brake on to test it. I was able to drive right off with the brake on! It was delivered to me in a completely UNSAFE condition! We had to diagnose this and repair it at my shop. The problem was easy to find. An axle seal had failed and allowed oil to pour into the brakes. The brakes were ruined with no pad material left and simply slipping providing no safety. This should have been alerted to me as it was easy to see without taking anything apart on the truck... the backing plate of the parking brake had oil all over it! This terrible sloppy careless mechanic isn't qualified to even touch a brake system. (see photos) I was driving the truck from GA to TN the same day. While fueling the truck I decided I should inspect the work to make sure my truck was safe. I noticed no one had removed the filler neck to the fuel tank, as all of the clamps had never been touched and had 15 years of dirt and grit on them. How did he remove the fuel tank? I checked the other end of the filler hoses at the tank... same thing... no one touched them. How did he remove the tank? Then I checked the four bolts that hold the tank in. No one had touched them!!! It was 100% clear that no one removed my fuel tank. They LIED IN MY FACE. This truck is a farm truck with a big hole in the bed for a gooseneck hitch. I looked in the hole and you could clearly and easily see the pump. (See photo) It is held in by just 6 small screws. One hose clamp on the fuel line, and one quick couple electrical connector. This pump can be removed and reinstalled in less than 10 minutes!!! How do I know that? There is a Safety Warning Tag on my new pump. The careless sloppy mechanic pinched the tag between the gas tank and the pump leaving an open airgap into my fuel tank and leaving my truck in a DANGEROUS condition!!! I hoped the tag would simply slide out as it was made of plastic, but it had been cut by the pump when it was tightened down. (See photo) In the end, I had to remove the carelessly installed pump myself, find the chopped off piece of tag, remove it from the sealing surface, and reinstall the pump myself. (See photo) Every single thing this terrible shop did had to be undone, and redone correctly by real professional mechanics, at a loss to me. Even worse, this terrible unscrupulous thief charged me 4 hours of labor for the 6 minutes of work it took to change the pump!!! I know because I had to repeat the job. To add insult to injury, they charged me $29 for "Supplies" when NONE where used, no even one penny's worth of chemicals or material were used to DEFECTIVELY assemble my truck and leave it in an UNSAFE and DAMAGED condition! I called the owner Matt the next day, and he admitted he had not removed the fuel tank, as he knew I had caught him red-handed STEALING FROM ME. He said he would refund 100% of my money the same day. I waited for almost 3 weeks, and have never received any refund, so I have file a dispute with American Express to get my money back. I have since had to have the parking brakes completely overhauled in order to make my truck safe. This matter will appear in a lengthy Youtube Video on my Channel, and will be reported to the Better Business Bureau, and other social media outlets in an effort to ensure no other motorists are victims of this horrible operation.
