I scheduled an appointment for an oil change with the Lexus of Maplewood dealership. I had a coupon for $30 off of any service. I checked with the scheduler of the appointment and with another employee of the Maplewood Lexus facility, if I could use the coupon. Both said yes. When I dropped off my vehicle, I signed authorization for the oil change with consultant James Smith. I received a call back from James who informed me that I should consider purchasing 2 tires and wiper blades. I declined the almost $50 charge for the placement & purchase of the wiper blades & another $565 for 2 new tires. I was informed that the tires on the front of my vehicle were in the "green zone" & the rear tires fell in the "red zone" A tire rotation was not done because I was told the better tires should be on the front, which was the case. When I picked up my vehicle, not only were there charges for a tire rotation, but also for a brake inspection. I was not informed, prior to the services, that I would be charged for a brake inspection. The total charge was very concerning to me, so I questioned the consultant, ( it was not James Smith, it was the consultant that is seated at the first desk as you walk in the service door), asking why I was charged for two services that was not performed. He said you signed for the services! I explained to him that the tire rotation was not done & I was not aware that a brake inspection was going to be performed and charged for! The consultant repeated saying you signed authorization for it, next time you should read the contract before you sign it. I again said the tire rotation was not done - I did not authorize a break inspection, nor was I aware that I would be charged for it. He again said, you signed the agreement. I then said, I was not going to argue about this with him, let's just get this done. He then took the charges for the tire rotation & the brake inspection off of my bill, but only after humiliating me in front of other consumers. This experience was horrible. I feel I was trying to be taken advantage of because I am female & wouldn't question the serve charges. This kind of trickory is abhorrent! I also question if the way I was handled, was because I presented with a $30 coupon. Lexus should reconsider their service training strategies to be more consumer considerate and not make them feel raped by their charges, especially services that were not performed!!
