Last year we started hearing squealing noises with our 2011 Buick Regal when we backed it out of the garage. We took it to the local Buick dealer several times and they were unable to hear the noise or figure the problem out. This was only occurring when the air conditioner was on and we were backing up or taking off. When they couldn't find the problem I offered to show the mechanic. The mechanic got in the car with me and I turned the air on and he finally heard the noise. He said he thought it was just the air-conditioning lines making the noise and I didn't need to worry about it. I explained to him that my warranty was about up and I wanted it fixed before it expired. The mechanic advised that it was well documented and it would be taken care of if it got any worse. We didn't have any problems over the winter due to the fact that we live in Ohio and we don't use our A/C. In May we started using our A/C again and the problem got worse. We made a morning appointment at our local dealer and dropped our car off. The dealer advised they would call us after they checked the car out. Around 4:30 pm we hadn't received a call so I called the dealer. The person that answered the phone said he would check with the mechanic. I wasn't put on hold and could hear the mechanic say he didn't have any help and it was a two man job. I was told that he hadn't finished the job and I made arrangements for my wife to be picked up at work and driven home by a family member. The next day we called the dealer and they didn't know where our keys were. The mechanic that was working on our car was off work for the day. I drove to the dealership to get some answers. Once I arrived they found the keys and got to work on my car. An experienced mechanic found the problem and they ordered the part on 06/13/2014. They advised the part would be in on Monday and they would call us when it arrived. They also said the problem was documented several times while under warranty but would not be covered due to mileage and the time frame between complaints. They did offer to knock $40 off of the $250 estimate. A week went by and no one called so my wife called and asked to speak with the employee that was suppose to call us. She was transferred to someone that apparently didn't realize a customer was on the phone due to the cursing. My wife said hello and the cursing stopped. The employee said hello and quickly hung up. My wife called back again and got a different employee and explained what happened. The employee apologized and said they had ordered the wrong part. She was assured that the new part was ordered and if she didn't hear anything by 6/24 to call back and that employee would take care of her. On 6/24 she called back and left a message for the employee to call her back. Guess what no phone call. I am done with Glockner's and will never use them again.
