If you want someone with expert level knowledge of Toyota-branded car lines...John Tucker is your man. I have a Lexus hybrid and was having an issue with the hybrid battery. All kinds of engine lights, couldn't be reset, couldn't pass inspection. I brought it to the dealership and their computer diagnostic spit out that 2 fuel cells were reading zero voltage. The dealerships conclusion was that the battery was shot and the only option would be to replace the battery entirely with a new one at a cost of $8500. My research into the secondary recertified hybrid batteries wasn't much better. A cost between $2000-2500 and a lot of anecdotal evidence of a high level of failure and warranty replacing failed batteries. It took me a few months to find my way to John's shop since I live in NYC and he's NH based, but as soon as I connected with him and outlined the issue, he had a few ideas of what the actual problem might be. As soon as he got his hands on the car, he confirmed that there was nothing wrong with the battery. The issue was the sensor that reported the fuel cell voltage to the computer. The leads connected to the 2 "zero voltage" cells were visibly corroded out. John swapped in a new sensor and voila! Problem solved. Cost of the replacement part? $650. John's expertise, problem solving and critical thinking saved me almost $8K. He knows what he's doing and has the years of experience to prove it. I would be skeptical of the cost of a dealership and the quality of their mechanics. In my case, I didn't feel like they dug deep enough into the problem to find out what the actual source issue was. They simply had an error code which justified the cost of a new battery and went with that when in fact, there was nothing wrong with the battery. Thank God for John and his ability to move beyond the obvious and not stopping diagnostics until he found the root cause of the issue. In addition to fixing the battery issue, he ran through my whole car and determined a set of preventative measures to get the car into top notch condition. He uses this amazing CRM software which makes everything he's doing and his reasoning behind fixes super clear and easy to follow. I normally feel like mechanics simply give you a raw dollar amount and I never feel like I know what the breakdown of cost is for. Not with John. Everything was laid out and make me feel great about the value of what I was paying for. John is a gem and you will not regret going to him for your car issues.
