Took care in for routine oil change and 75k checkup. Found a few minor issues and got the car back the same day and is running better than when I dropped off. I feel very comfortable that Hillmuth will keep my 2010 Rav4 running like new for many years to come.

I have been taking my cars there for almost 20 years and have always had a great experience. The talk to you like a person and not a mechanic so that it is understood for the repairs that needs to be performed on your vehicle. I will always have my vehicles serviced at Hillmuth unless something drastically change, meaning service, pricing, etc.

by - Verified Customer November 21, 2013

The service was timely and excellent!

Courteous service.

by November 01, 2013

The associate was very dishonest with me and tried to swindle/con me out of $1700 of service that could have been done for free under my 5 year 100k factory warranty. I took my car in for an engine sound and mentioned that it may be covered by my 100,000 mile warranty. He told me he called Chrysler and they told him it was not covered because my warranty was 5 year 60k and I was at 61k miles and they would charge more than his $1700 quote. I called the dealership and they informed me that it was covered and it would be free because I was covered up until 100k miles. I called the Hillmuth rep on three way and his story changed. He informed the dealership rep and me that he said the warranty doesn't work with him but he would do the work for me for a discounted price but if I wanted it done by Chrysler, I would have to go there to get it done. I asked him why did his story change. He told me he thought I just preferred Hillmuth to do it. He never called Chrysler to check anything and tried to lie about the call and our conversation. BAD BUSINESS ETHICS... I basically paid $85 for him to confirm the problem I said I was having with my car and for him to lie to me to get more money.

Reply from Hillmuth Certified Automotive of Gaithersburg – by Hillmuth Certified Automotive December 13, 2013

First of all,I would like to state that our company has been in business for 36 plus years. You do not reach that level by having "BAD BUSINESS ETHICS".We value every sale as would any business ,but not at the expense of our reputation. Whenever there is a possibility of any manufacturer warranty coverage we always try to get that info by calling the dealer ourselves for the customer. When there is warranty coverage left we always urge our clients to use it so there will be no expense to them. We are only able to go with information provided to us by the dealer.Sometime it may not be correct information. Again, we always try to have our clients best interests at heart.
