I was referred to John by AAA when my car overheated. I requested for John to complete a full inspection of my work van to make sure nothing else major is going on. John informed me that I had a bad heater valve. I also told John that I had a small oil leak coming from my rear main engine seal according to my dealer Chevy. John then told me to bring my work van back next month so he can confirm if there is a leak from rear main seal. So John gave me an estimate for $1,000 to fix my heater valve which I approved. A week later John’s office employee Melissa called me to inform me my work van was ready for pickup. I asked her if the van had been test-driven. she said yes. So I arrived to pick my work van up after paying. I left and turned on my A/C which didn't work then realized my radio didn't work either. So I called Melissa. I told her my radio and A/C was not working and she told me to bring the work van back which I did. John , the mechanic, said he forgot to reconnect the A/C wires which was taken care of but not the radio. Unfortunately he said there is nothing they can do about that. It must have happened when the van overheated. I said okay but this didn't sound right to me. A month later my engine oil began to leak more so I took it back in to John’s shop and again I asked John and Melissa to fully inspect the van and check all fluid levels, brakes, and codes, if any. John said it was leaking from the valve cover gasket so I asked John about the rear main seal which the dealer informed me, was leaking from. John said he would like to repair the valve cover gasket first and see if it was still leaking oil. So John repaired the valve cover gasket and did my back brakes and aligned my work van as well. The bill was about $2K which I paid. A month later, my engine oil was leaking really bad. My engine light came on, reading low engine oil pressure and instructed to turn car off, which I did. I called John to let him know and he told me to bring it in which I did. John then informed me that it is leaking from rear main seal. So I asked him if I need to get a new work van. John replied that there was no (?) that he can fix rear main sealed that is leaking oil. So I told John before repairing rear main seal, to please check to make sure nothing else is wrong with my work van. And also email John’s office staff as well to inspect my work van. I called John’s office to get an ETA. Melissa answered my call and she wasn't too happy and had an attitude like she didn't want to be bothered. She said my van would be ready on Friday so I told her that I need to get some tools from my work van and asked if I could come over. She said yes. When I arrived, my car was on a lift still so I asked about it. John said he had to remove the transmission out again cause the van was not shifting. I asked if it would be ready the next day. John confirmed that the van would be available. After leaving, I got a call from Melissa, instead of John, informing me that she had “good and bad news”. “Good news” was rear main seal was. replaced and repaired, and the “bad news” is transmission is now bad. Melissa told me she would have to charge me for the transmission and my reply was “why should I have to pay for a transmission that your mechanics damage?”Melissa was rude and said if I didn’t pay, I would not get my work van back. I informed Melissa I would rather buy a new van since the mechanic shop refuses to pay for my transmission which they damaged. The repair shop, Shalom, wanted over $3K and now they refuse to return my work van. Finally, I will report John and his company to BBB, consumer report, and take him to small claims court. Please don't use or recommend this company to your family or friends . This mechanic shop is run by dishonest people and will hold customers’ cars if damaged by them and if you decide not to approve their estimate. John and Melissa never informed me or asked me to sign a waiver regarding transmission. They failed to inform me, as the customer, of the possibility of permanent damage when replacing rear main seal and transmission. I would like my work van back A.S.A.P. if John not willing to replace my transmission that he damage by accident or due to his inexperience. Or release my van that is not working due to a damage transmission cause by John. I have tried to work with john and his team and they refuse to work with me instead they put the blame on me and refuse to reply to my emails.
