I don’t write reviews but feel the need to for this order. I ordered an alternator for my 03 dodge ram 1500 5.7 hemi. The part was assured to fit with their compatibility system. When I received the part the box had the correct part number on the label but the quality check paper had the wrong part number on the top. Before I took the old alternator off thankfully I compared the part I received to the old alternator and found the mounting brackets were different and the connector was wrong. I contacted customer support and was told to fill out a customer support ticket and attach photos. I asked the customer support lady if the part number on the quality check sheet should match the one on the box and she advised me that the paper is outdated and had nothing to do with the part which was wrong, I then asked her what the difference was between a denso and Bosch type connector because the 03 ram was made with both of those connectors from the factory. She could not tell me the difference and told me I would need to take it to a local shop to have them tell me. I submitted the ticket with photos of the new and old part and was advised I would hear back from customer support. A week went by and I called customer support again to check the status and the lady advised me that the review was over and I needed to send the part back. I asked if they would send the correct part to me and she said they would not send the part or help me and that I would need to get the part locally. So absolutely no help on their end. I ended up getting the part at autozone for double the price. Guess what the part number on their quality check sheet matched the part number on the box. The part was a “plug and play” and I’m finally able to use the truck again. I have bought one other part from 1A auto before this incident with no issues and was pleased with that part. In conclusion 1A auto customer support should be ashamed of their performance and lack of help or what they call “customer support” and I will not be using them in the future. They never took blame for sending me the wrong part and having my truck sit in the yard as a big paperweight waiting on them to resolve the problem they created. In short just do better in the future. I am still awaiting the full refund but don’t expect them to get it right and deduct the shipping label cost of $40 so I’m sure I’ll be talking with them on the phone again. Hopefully this review helps someone avoid the hassle I went through. I would attach photos but it keeps giving me an error to upload them.
