No games, no shady stuff... just honest, reliable work from genuinely good mechanics. Every time I feel something is wrong with my car, I take it in and Ed takes the time to personally inspect my vehicle for everything until he finds what to be fixed. They never overcharge and their prices are so totally fair in my opinion. I never feel talked down to or taken advantage of. I fully trust them, which says everything. I'll never take my car anywhere else for as long as I live here. They've earned a customer for life.

He completely butchered all the sensor wires because he messed up and clearly didn't know what he was doing. He ran the wiring harness in the wrong direction and had to add wire in and caused misfiring in my engine and all kinds of different sensor error codes. He zip tied the wires to anything he could. Because of his lack of knowledge and professionalism the re-wiring he completed shorted one of my modules. I took my car to Georgian BMW right after and they confirmed they did a botch job with photo evidence. They wrote everything JB Tire Tec did in detail in the invoice. This cost me over $3300 to fix. He is not responding to any of our text messages. We can see the read receipts and he is completely ignoring us and not taking any responsibility. Shame on him! Do not ever do business with this man. He will ruin your vehicle and cost you thousands of dollars. Look at the photos the dealership sent me. Its absolutely gut wrenching to see this kind of work done to your BMW.

I brought my 2016 Audi Q5 in on December 15 for a scheduled 115,000 km service, including a brake…read morefluid flush. During the service, the advisor, Albion, contacted me and said the front brake rotors were corroded and the pads measured 5 mm. He specifically asked whether I had noticed that the brakes felt soft. When I confirmed this, he recommended replacing the front brake discs and pads to address the soft brake pedal, at an additional cost of $1,730. I approved the work based on this expert recommendation. After picking up the vehicle, the brakes still felt soft and required deep pedal travel to stop. When I followed up the next day, I was told that soft brakes are "common in older Q5s. And no adjustments can be made to resolve this issue." This is unacceptable. If the brake softness is a known characteristic and not something that replacing discs and pads would resolve, then recommending a $1,730 repair as a solution was misleading and unnecessary. I paid a significant amount based on professional advice, only to be told afterward that the problem was "normal" and effectively unfixable. Brakes are a critical safety system. An Audi service center should provide accurate diagnostics and honest recommendations, not sell costly repairs that do not address the customer's safety concern. This experience felt deceptive and has completely eroded my trust. I would not return here and cannot recommend this service center to anyone who values safety and transparency. Stay away from Audi Newmarket for your own sake.

I am writing this to warn anyone considering the 2025 Audi SQ6 e-tron. After waiting over a year…read morefor my factory order from Audi of Newmarket, I have been left with a vehicle that has significant, recurring safety malfunctions and a dealership that offers zero accountability. Despite being marketed as a flagship of innovation, my vehicle has suffered from the following critical failures since delivery in January 2025: High Voltage Electrical System Malfunction: "Drive with caution" warnings. All-Wheel Drive & Charging System Failure: Multiple system-wide malfunctions. ABS & Driver Safety Monitors: These systems frequently shut down entirely during normal Canadian weather (light rain/snow), disabling collision-avoidance features. When I raised these life-threatening concerns, the General Manager at Audi Newmarket admitted to me: "I am very familiar with the 'system unavailable' messages as I experience them too." It is professional negligence to continue selling these vehicles while acknowledging that even management's own cars are failing. The dealership claims the car is "too new" to fix, and Audi Canada has been completely unresponsive to my repeated attempts to reach them. Audi of Newmarket and Audi Canada have shown zero consideration for customer safety. If you value your safety and want a reliable EV, do not lease or buy this vehicle. I am now forced to escalate this to regulatory authorities to hold them accountable. In normal Canadian weather rain, snow & the vehicle frequently reported that safety systems were unavailable. This directly contradicts Audi's own marketing claims about advanced collision‑avoidance and driver‑assistance technology. The repeated failures of the safety monitoring systems, especially under normal driving conditions and inclement weather, raise significant concerns about the reliability and safety of this vehicle. I believe these issues warrant immediate investigation and intervention by the appropriate regulatory authorities to ensure consumer safety and to hold the manufacturer accountable for addressing these defects.
