There are 2 owner-reported suspension complaints for the 2018 Mazda CX-5in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The contact owns a 2018 Mazda CX-5. The contact stated while having a routine oil change, the mechanic noticed that the rear shocks were leaking oil and needed to be replaced. The vehicle was not replaced. The manufacturer was informed of the failure and informed the contact to bring the vehicle to a dealer for assistance. The failure mileage was approximately 27,137.
Our 2018 CX5 has only 28K miles. During a recent oil change at our local auto repair facility I was informed that the driver's side rear shock was leaking oil and needed to be replaced. After some research I found there is a Mazda TSB (Bulletin No.: 02-001/21) stating that many 2017-2020 CX5s left the factory with defective rear shocks. In my opinion, loss of shocks could affect stability of a vehicle and cause a crash. There should be a recall to replace these defective shocks!
