Differential repair service near Laurel, MD

I look forward to continuing my business! Great experience.

The people were very friendly and helpful. I decided not to get some of the work done there as I found much cheaper options elsewhere, but that was my choice and not a problem with Nielson’s. My main frustration is that a day after I had my car looked at there (and had the problems they identified addressed by another cheaper garage), the car failed a safety inspection for three things that did not show up anywhere on their report: parking break not holding, and a front and rear marker light out. Those seem like very easy things to identify, especially the lights, so not sure why they were missed.

I recently took my Mercedes to this shop for repair because after owning the car for 12 years, I am tired of the pretentious attitudes and high prices of the dealership service department. API is a great alternative. The people who work at API are familiar with Mercedes cars, have the right tools to service them, and are able to get the right parts. Most importantly, they are friendly and make their customers feel valued. I plan to continue taking my car to API for future service needs!

This place was recommended to me by a near by shop which I have gone to in the past since they were not able to service my vehicle at the time. Overall my experience was wonderful. I was greeted by friendly staff who were efficient and professional. The individual assisting me was attentive and he explained things in simple terms since I am not too familiar with service/mechanical issues concerning cars. I would definitely recommend this shop to my friends and family and anyone in need of a quality shop.?

Went there on Oct 16, 2015 for a simple oil change, have already filed with the BBB, car was running fine, told me I needed a qt of transmission fluid, I said fine, the minute I left the car began bucking, that was a Friday, please also note I am a female, on Saturday really didn't drive much as my son took me to PA in his car but when I did in the early am still the same problem, bucking and not shifting appropriately. On Sunday took the car to Walmart, much worse, it actually shut off, check engine light came on, cruise control light came on, had to turn off car, wait, gingerly start back up and ease my way back home. I called my mechanic. He came over. Let's start with the fact that I was 1 1/2 quarts low on oil (2 days after an oil change) and my transmission fluid was bone dry), he put 2 1/2 quarts of transmission fluid in, told me to go to work the next day have the guys pull it in the shop and hook it up to see if it throws any codes and then go over it with a fine tooth comb. See what Charm City didn't know is that I really hate to bother my mechanics for an oil change so I go there, but I've been working with mechanics for 16 years, so they pulled my car in the shop went over it and still had to add another quart of transmission fluid. My certified mechanics have told me that either charm city pulled the transmission plug and drained the tranny fluid or they used a fluid evacuator, when I confronted the owner who took offense to my language and really who wouldn't be pissed, he could have blown up my transmission..he lied, he said a fluid evacuator takes an hours...sorry bud....5 to 8 minutes....his mechanic lied and said he put 6 quarts of oil in my car...first off...why would you put 6 quarts when you only need to put 5 and you didn't put 5...liar...I don't care that you've been in business for 26 years, you saw a female coming in who never uses you for service and you thought you could get some service work from me, so you drained my tranny fluid and then had the gall to ask why I didn't come back, because you are untrustworthy, BEWARE ONE AND ALL. I have 2 certified mechanics that will testify to my story. This place needs to be investigated!!!!
