While driving, Low Engine Oil light illuminated. Vehicle has 9968 miles at time of incident and had one oil change at 5873 miles.

I have the 2.5 liter turbocharged engine in my CX-30. It currently has approximately 18,000 miles after a little over a year of ownership. So far I have had to put in 3 quarts of oil in that time. The engine/low oil indicator comes on about every 4,000 miles. When I check the oil, it shows that it is down a quart. I have taken it in for regular service (oil and filter, tire rotation) twice now, and have brought this to the attention of the service advisor who tells me that this is normal for turbo engines. I disagree with this assessment. I wi…

My car was squeaking and lurching around 3/4 gear. I took it in to the Mazda dealership (Northtowne Mazda in Kansas City) and they told me it was a "well-known issue" with this year and make of a Mazda. There is a problem with the torque converter lock-up clutch which sheds iron particles into the transmission fluid. The torque converter needs to be replaced. After further research, it appears that Mazda has a well-documented manufacturing defect that is outlined in Mazda TSB 05-005/23. My car has a 60,000 mile/5 year warranty on it. It current…

I am reporting a repeated and potentially dangerous transmission failure in my 2020 Mazda CX30. At 6 months old, the original transmission failed. Mazda confirmed it was defective and replaced it with a refurbished unit with 10,000 miles on it. That replacement is now also failing, within 4 years of the first failure. This means the car has experienced two transmission failures before reaching 5 years of service. This raises concerns about: •The reliability of Mazda’s factory parts •The quality and safety of refurbished transmissions Mazda use…
