2020 Mazda CX-30 recalled for brake caliper problems

Mazda is recalling 24,000 CX-30 SUVs and Mazda3 small cars from the 2020 model year to inspect and tighten bolts on the front brakes. If the front caliper mounting bolts (which hold the components that squeeze the brake discs to slow the car) come loose, brake performance could be reduced and the bolt could interfere with wheel rotation. Either scenario increases the risk of a crash.

Mazda estimates just 1 percent of this group has this defect. However, all owners of these vehicles should take the problem seriously and have their SUV or car inspected as soon as possible. This recall is expected to begin Aug. 11, 2020.

“People who own these vehicles shouldn’t wait for the recall notice, given the nature of the problem,” says John Ibbotson, Consumer Reports’ chief mechanic. “This is an easy inspection to perform, and the problem is serious.”  

Mazda confirmed to Consumer Reports that vehicle owners do have the option of visiting the dealer for inspection and remedy prior to receiving an owner recall notification letter.

The Details

Vehicles recalled: 2020 Mazda CX-30 and Mazda3 built between Oct. 22, 2019, and March 06, 2020.

The problem: Due to a manufacturing error, the front brake caliper mounting bolts may not have been tightened properly during assembly, possibly allowing the calipers to loosen. Drivers may hear “abnormal grinding or rattling” noises coming from the front, indicating a serious problem.

The fix: Dealerships will inspect the front brakes and tighten the caliper bolts as necessary. If the bolts are missing, they will be replaced. All repairs will be done free of charge.

How to contact the manufacturer: Owners may contact Mazda customer service at 800-222-5500.

NHTSA campaign number: The recall number is 20V346000. Mazda’s own number for this is 4420F.

Check to see whether your vehicle has an open recall: NHTSA’s website will tell you whether your vehicle has any open recalls that need to be addressed.

If you plug your car’s 17-digit vehicle identification number (VIN) into NHTSA’s website and a recall doesn’t appear, it means your vehicle doesn’t currently have any. Because automakers issue recalls often, and for many older vehicles, we recommend checking back regularly.
