EXCELLENT Based on 13 reviews Posted on WarlyTrustindex verifies that the original source of the review is Google. Finally pull the plug and went with this shop....Thanks to Leon's team for honest and great customer service. I had to take my wife's Tesla model Y to his shop for HV battery replacement because tesla replacement is just way too much, EV REVIVER is reasonably lower than TESLA's quote although the warranty coverage has a difference of 1 yr/14K miles, I think it's still a good and way better deal. If you own a TESLA or any EV car and looking to save some money or at least an option to save money, this is the shop you need to go to...Owner exhibits a good, upfront, and great customer service. Highly recommend to check them out, thank you EV REVIVER!Posted on Arnaud J ForestierTrustindex verifies that the original source of the review is Google. My 2016 Tesla model S battery drained entirely, and I had no way to tow the car anywhere. I called EV reviver, and though they couldn't come over, they sent me on-line instructions on how to pop the hood to get to the 12V battery and get the car started. I saved a lot of money thanks to them, and the help came for free. Honest and competent people, you can trust them.Posted on BTrustindex verifies that the original source of the review is Google. My Tesla at the time 180,000+ miles Suddenly, my “battery dies” Tesla wants me to pay almost $20k to replace the battery Leon and his team found a better solution The repair cost me a fraction of what I would have paid to tesla for a new battery. Process was smooth If you own a Tesla, and battery issues, this is the team to go to.Posted on Mike MurrayTrustindex verifies that the original source of the review is Google. I wish I would’ve known about these guys sooner.My Tesla model X performance was bricked. Turns out I needed one module in the high voltage battery replaced and Tesla wanted $16,450 and 7 days To get my car moving again. I was stuck. I took it to these guys. They fixed it for less than a third of the price with a three day turnaround. If it wasn’t for Ev Reviver I would’ve been big-time screwed. Never pay Tesla until you consult Ev Reviver first. This is a no BS review. I’m not paid to tell you this. Tesla repair shops are legitimate crooks. We’re lucky to have guys like Ev Reviver. Even if your car is not operational, these guys can give you an estimate and you can have it towed there. Or you can get robbed by Tesla it’s up to you.Posted on angel mendozaTrustindex verifies that the original source of the review is Google. Took care of my Model Y battery error codes and replaced one of my neighbors model s batteries as well. Amazing service.Posted on Cody NoviniTrustindex verifies that the original source of the review is Google. Finding an EV repair shop you can truly trust isn’t easy—but EV Reviver is the real deal. From start to finish, Leon and his crew delivered the kind of service that’s rare these days. They were punctual, professional, and most importantly, honest. After getting a few overpriced quotes elsewhere, I was relieved to find someone who actually took the time to explain what was actually wrong with my car—without trying to sell me on unnecessary work. And he did higher quality work than the competition. Their pricing is more than fair, and the customer service? Top-notch. They treated me with respect, communicated clearly, and got the job done right the first time. You can tell they genuinely care about helping people, not just making a buck. If you’re having issues with your Tesla or EV, don’t waste your time or money anywhere else. EV Reviver is hands down the best experience I’ve had with auto repair—period.Posted on Michael MohrTrustindex verifies that the original source of the review is Google. Great experience. They went above and beyond answering all my questions, and you can immediately tell they care about their customers and know their stuff. Much appreciated 👍Posted on Thuy PhanTrustindex verifies that the original source of the review is Google. I have Tesla 2015 with over 150,000 miles. I am so worry about battery and brake. I brought to Tesla dealer for diagnose, i paid aound $500.00 and they did not give me the answer, Tesla told me that they could not diagnose about battery life. Finally i came to EV REVIVER, my problem is solve, at this shop they had the test and through their diagnose i can see clearly how is situation of my car. Professional people, trusting place. Highly recommend to everyonePosted on Danh TranTrustindex verifies that the original source of the review is Google. I brought my Tesla to Leon shop and he took good care of my car. Highly recommend. Don’t want to say more but thank you so much for your service to my Tesla. 😁😁😁Posted on Paul BATTLETrustindex verifies that the original source of the review is Google. I called them with my possible 12v battery issue when my high voltage battery on my model S Tesla was zero charge in Atlanta. They are based out of southern california. They called me back twice to check and see how I was doing despite the fact they knew I could not use them in Atlanta.I was visiting in San Diego and got their number online. They were very helpful to me explaining every scenario I might have with my 2017 model S Tesla. I would encourage anyone to call them for advice or service. They were very knowledgeable!!Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
