My recent experience with the service at Putnam Mazda was extremely disappointing and frustrating. What should have been a routine visit turned into a distressing ordeal. My car suddenly died on the freeway without warning lights, prompting me to bring it in for servicing. Initially, I appreciated being offered a loaner car. However, subsequent communication regarding the repair was inadequate and concerning. I received an email stating the necessary part wouldn't be available until July and was abruptly instructed...

to return the loaner car immediately, with no consideration for my circumstances. This lack of empathy was shocking, especially as a loyal Mazda customer. Furthermore, I experienced racial and gender profiling throughout the ordeal. Instead of addressing my concerns, I was met with aggression and threats of police involvement, making me feel targeted and discriminated against. When I questioned this response, I was told my email was "direct," justifying the aggression. Additionally, the loaner agreement lacked an expiration date. Despite being assured they would provide a grace period if needed, I was demanded to return the car immediately, with false claims about the agreement. This manipulation, gaslighting, and harassment are not only unethical but also against the law. To exacerbate matters, safety concerns with my vehicle were brushed aside. Despite my car having a non-working engine, the dealership suggested I drive it off the lot. This reckless recommendation not only endangered my safety but also the safety of others on the road. Despite repeatedly expressing these safety concerns, the dealership did nothing to address them. Responding to a concerned customer with threats of police involvement is never justified. Instead of addressing my concerns, I was met with aggression and threats. They threatened to report the car stolen and demanded I drive my car without a working engine. This behavior was unwarranted and left me feeling insulted and degrad
On November 4, 2022 I was driving in the middle lane of I 87 north of Saratoga Springs. The car stalled and died. I was able to get to the break down lane. After sitting for 5 - 10 minutes, completely frazzled, I tried the ignition and the car started. The gas gauge said I had approximately ¼ tank left. I filled the car up and made it the rest of the way home. This had happened once before on a local road and we had the car towed. The thought was that maybe the car had run out of gas although the gas gauge did...

not so indicate. When I took the vehicle to the mazda dealer after considerable research, they indicated there were recalls on Denso fuel pump impellers for the model of my car in 2018 and following but not for my 2017 model. The date of that service was 1/17/23. There were no codes still in place that would identify the problem. I am certain that this is the problem. I only drive the car locally now and i keep the gas tank at least ½ full.

Engine stalled while driving and all the dashboard lights turned on. Could not turn engine back on again. Upon inspection, it was found that the fuel injector pump was faulty and was subsequently replaced by the dealership. Fast forward a year, check engine light came on and vehicle began to stall again. Dealership states that the fuel injector burnt out due to the initial fault in the fuel injector pump. Furthermore, it burnt out my catalyst.
While driving 70 mph on the interstate, vehicle stalled and started jerking, unable to accelerate, losing speed quickly. Fortunately I was able to move onto the shoulder, avoiding a semi truck approaching quickly behind, and another semi trucked parked along the interstate blocking access to the shoulder.
I was in an accident at a very high speed. A driver didn't see me in his left side blind spot and was veering into my lane at 85-90mph. I swerved to the left to avoid the car and my car wouldn't straighten/i couldn't get back the control. I smashed the guardrail with the whole left side of my car and the car was deemed to be totaled by the insurance company. The airbags never deployed despite the high speed and impact of the accident.

While driving on a 4-lane road (~45 mph), the vehicle lost all power and died. The check engine and battery warning lights came on and the start/stop button light turned red. After coasting into a gas station, the car could not initially be restarted. It could be restarted after adding gasoline, although the fuel tank was not empty when the car died. The fuel gauge showed 1/8 tank, and 9.3 Gallons fuel could be added to the tank, which has a capacity of 11.9 Gallons. After adding fuel and restarting, all warning...

lights went off and the car could be driven normally again. The mazda dealer found no stored error codes in the system and verified that the fuel pump and gas gauge were working correctly. Dealer performed powertrain control module software update.
Key fob disconnects while driving. Lock/unlock does not work. Car does not start when keyfob is in vehicle. This has happened three times now, the dealership has changed my keyfobs, flashed the memory, and replaced the batteries. I've spoken to corporate customer service and was told "sometimes key fobs just disconnect. Please exit the vehicle, wait, and try again." I'm currently waiting for this to happen a fourth time.
