A D V E R T I S E M E N T S

The contact owns a 2021 Mazda CX-5. The contact stated that while stopped at a stop sign, the vehicle failed to accelerate while the accelerator pedal was depressed. The contact restarted the vehicle and corrected the failure. The vehicle was taken to the dealer. The dealer performed a Special Service Program (SSP) Recall #: SSPC7 (TCU Connect Concern CV/Battery) where the TCU software was updated; however, the failure recurred. The manufacturer was made aware of the failure and informed the contact that there was no additional recall associated with the VIN. The failure mileage was approximately 300.

Bought the car brand new in May 2021, did a first oil change at around 4K miles due to the fact the car uses conventional 5w-30 oil and not synthetic oil. At around 7k miles the low oil engine light came on. Checked the dipstick and it was low. Added a quart of oil to hold me over until the next available appointment. Dealer could not find any leaks, they completed a oil change again. I went in again at 11K for another oil change. Had no problems. A few days ago at 14K low engine light came on, this time I turned the car off. Let it sit over night. Made an appointment with the dealer for the next day. Turned the car on the next morning, light went away. Both times I got a notification from Mazda connect services alerting me of these problems. (Please see attached) I brought the car in on 12/22/21 and was told the car was low on oil and nothing else could be done until Mazda comes up with a solution.

ON Nov 4th my Mazda CX5 alerted me to low engine oil level by illuminating dashboard symbol and app notification. I attached a file containing an explanation of the issue, emails directed to Mazda corporation and Napelton Mazda in Naperville IL. I also attached screenshots of the in app notification and the Mazda TSB which I had to find on my own because Mazda coporate and both the selling/servicing dealer would not acknowledge the oil burning issue.

On 17-MAY-2021 after sitting unused for 1 day my Mazda CX-5, mfg year 2021 with about 1,500 miles did not start. All electrical systems failed, there was no indication of any power present. The vehicle is presently at the dealership it was purchased at about 90 days ago, 495 Mazda in Lowell MA and is available for inspection. The sudden loss of all electrical systems has the potential for stranding the driver and passengers in dangerous locations. The problem has not yet been reproduced. The vehicle has been inspected by the service department of 495 Mazda in Lowell MA who advised they had charged the battery and tested it as ok and offered to return the vehicle to me. There were no warning lights or other indication of this problem. This morning when I called for service, the dealer, 495 Mazda informed me they do not pick up failed automobiles and I should either call Mazda roadside assistance or jump start the car and bring it in. I measured the battery voltage at 2.5 volts and charged it with a high quality battery charger. The car then started. After shutting off the car there was a faint buzzing sound from the engine compartment. I advised the dealer service department of all these details. I would also note that after the car started I measured the battery voltage at over 14 volts proving the charging system works, after shutting off the engine the voltage dropped to 12.1 volts.
