On 1/4/24, I took a vehicle that needed repair/diagnosis to Electric Laboratories on ****************************** in ******. I contacted ********* the Service Tech. and requested that the vehicle be diagnosed for an electrical drain that was quite pronounced as the vehicles battery would consistently drain overnight. I paid the almost $400 fee as I already took the vehicle to my regular mechanic who didnt have the updated computer equipment to diagnose the drain, he suggested that I take the vehicle to Electric Labs as they advertise that they are the best and guarantee a diagnosis.Upon dropping off the vehicle, I received a receipt for the payment and a report stating that they would diagnose the electrical drain, this is the only paperwork I received from Electric Laboratories.On 3/5/24, I ended my relationship with Electric Laboratories, almost a full two months later, still with no diagnosis to the problem. I requested a refund for the diagnosis as they made none and was declined by *******, the manager, below is a synopsis of my interactions with Electric Laboratories, (I do not have exact dates as I was provided no paperwork besides the initial meeting with *********).*In the first week or two, I was told that the vehicle drained while on their lot twice.*In the third or fourth week, I was told twice to come pick up the vehicle as it was running, charging and had no drain, both times the vehicle drained overnight, I charged the battery both times and returned the vehicle.*In the weeks following, I was told that the vehicle had a diagnosis of intermittent charging. I took the vehicle home. On the way home, the vehicle died as I turned onto my street, (luckily, I live nearby) and I almost didnt make it home. I charged the battery fully, (new battery).In the week or two following this I found that the main electrical wire to the alternator was disconnected, the wire was wrapped in a rag. I immediately responded to Electric Laboratories where I reported the disconnected wire to *******, he questioned me about working on the vehicle myself, I assured him I had not touched the vehicle as I had paid $400 for him to diagnose.******* had a worker respond to my house who took the vehicle back to their shop for more diagnosis as the intermittent charging diagnosis claim was baseless.*Shortly thereafter, I was contacted by ********* who again explained that the diagnosis was intermittent charging and told me the vehicle was ready for pickup, I informed him that I would respond to pick up the vehicle but wished for someone to show me the diagnosis on their equipment as the vehicle ran, ********* assured me that this could be done.A short time later, I arrived, and test drove the vehicle as the wire was now attached to the alternator, the car drove fine. Upon arrival at the shop, I was met by ******* who informed me that he could not show me the diagnosis as the problem was intermittent, I assured him that I had time and patience and would wait, ******* told me that could not happen. I told ******* that I was suspicious and skeptical of the diagnosis and was not satisfied with his shops work. He told me that he could place the vehicle on an overnight diagnostic machine which could give an accurate diagnosis of the drain. I immediately inquired as to why this hadnt yet been done in the last month or so that they had possession of the vehicle, ******* had no answer but agreed to take the vehicle back for the test which he explained would occur that night.*The next morning I called the shop and talked to *********, he told me that there was a new diagnosis, he continued and told me there were several error codes and that they felt that the battery was bad, I thought this odd as the battery was only a few months old an had not been mentioned until now.*Later that morning, I responded to the shop and inquired as to who ******** supervisor was, he informed me that ***** the owner was his supervisor.At 130 pm, I responded back to the shop and met personally with ***** alone in her office where she recorded the conversation with my consent.I explained to her the failed efforts of her shop and my suspicions that her employees were untruthful, she assured me that she would fully investigate my allegations and call me back.Later that day, she called me and told me that the new diagnosis was in fact a bad battery, I agreed to purchase a new battery from her for $170, but requested that she keep my old battery as it was new and I was skeptical of the new diagnosis, she agreed and, in the days, following I picked up the vehicle.In the days following, I attempted to start the vehicle and again found the battery dead, I called ******* and informed him, later that day I removed the battery and took it to the shop. ******* couldnt locate my old battery and agreed to refund me the $170, a few days later, he called and informed me that he had completed the refund, I requested a refund of the $400 diagnostic fee and explained that I knew he needed to talk with *****, and I would call back in a few days.I called him back a week or so later where he informed me that he had in fact talked to ***** and she decided to decline the refund. I accepted this and informed ******* that I would first pursue a complaint with the ****** of ********** Repairs, then if unsuccessful other remedies.Im very disappointed with the staffs performance at Electric Laboratories: -they advertise that they guarantee a diagnosis and theyre the best in town. -They failed to diagnose my vehicles problem, -in my opinion were untruthful, -sent me home with the alternator wire not attached, -accused me of breaking it, -lost my battery, -and didnt provide detailed paperwork during our many interactions.
