Why Precision Auto & Diesel
Family-run and trusted across Yonkers and Westchester, from Bronxville to New Rochelle. No hidden fees. No upsells. Just ASE-certified hands, straight talk, and every qualifying repair backed by a 24-month / 24,000-mile nationwide warranty — because that's what standing behind your work looks like.
"Honest, upfront price, finished the same day — I'm not going anywhere else."
From our customers
"Brought my truck in for a brake job after another shop quoted me sky-high. Precision gave me an honest, upfront price, finished the same day, and the brakes feel brand new. ASE-certified techs who actually explain what they're doing. I'm not going anywhere else."
"My check-engine light had been on for weeks and two places couldn't figure it out. These guys diagnosed it in under an hour, showed me the actual sensor that failed, and fixed it for a fair price. No guesswork, no parts I didn't need. Highly recommend."
"We run a small delivery fleet and Precision handles all our diesel service now. Fast turnaround on DPF and injector work, fleet pricing, and they keep our trucks on the road. Easily the most reliable shop in Westchester."
"Needed a NYS inspection and was dreading it. They got me in quickly, walked me through one small thing it needed, fixed it on the spot, and I drove out with a sticker the same morning. Friendly, honest and quick."
"Engine was knocking and overheating and I thought it was done. Precision diagnosed a cooling issue instead of pushing a rebuild, saved me thousands, and stood behind the work with their warranty. Straight shooters — exactly what you want from a mechanic."
"Came in for an oil change and they did a full courtesy inspection without trying to upsell me on anything. Caught a worn belt before it left me stranded. Clean shop, fair pricing, and they treat your car like it's their own."
