2010 Mazda MAZDA3: ABS light or ABS activating

Filed Aug 27, 2025 · Brakes · NJ

On August 15, 2025, my 2010 Mazda 3 began displaying the ABS warning light intermittently while driving. The ABS system is a critical safety feature, and when the light comes on, I am unsure if the braking system will function properly in an emergency. I scanned the vehicle using a Foxwell diagnostic tool and retrieved the following ABS-related fault codes: C0020:1C-2B – ABS Pump Motor Control Circuit U0425:62-60 – Invalid Data Received from IPC/ABS Control Module U0140:00-28 – Lost Communication with Body Control Module These issues are consistent with Mazda Technical Service Bulletin 04-002/13 (July 17, 2013), which documents ABS pump motor failures caused by poor motor brush contact. This is a serious safety concern because the ABS system fails without warning, leaving the driver and passengers at risk of brake loss in critical conditions. Why this should be investigated: The defect occurs intermittently, making it difficult to predict or reproduce. It matches a known documented defect acknowledged by Mazda in TSB 04-002/13. Other owners have reported similar ABS pump failures in Mazda vehicles of this generation. The failure compromises safe braking and should be treated as a safety defect warranting investigation and possible recall. Action Requested: I am requesting that the federal safety agency investigate this recurring ABS pump/motor failure in 2010 Mazda 3 vehicles and determine whether a recall should be issued to address this known defect.

ABS will cause complete brake failure when it is engaged. For example, needing to stop quickly to avoid hitting another vehicle and the brakes will lose all pressure and the vehicle will not stop. Several mechanics have not been able to diagnose or fix. Immediately after the incident, there will be minimal brake pressure of about 20%, eventually it will return to normal. Must avoid applying brakes in emergency situations as it will actually be worse than attempting to steer out of it. This has happened about 6 times in 4 years. It happened the first time about 3 days after I bought the vehicle in 2019.

Component: ABS Hydraulic Unit; How was safety at risk: The failure of the ABS system clearly poses a risk; Reproduced: The original ABS Hydraulic Unit has a known design flaw that causes it to fail under mild environmental conditions (see, e.g. SB-10053757-3542); Inspected: The problem has been diagnosed by an independent mechanic; Warning lights: The ABS light (and occasionally DSC and BRAKE lights as well) sometimes became illuminated.

Had my ABS and brake lights come on so I immediately looked these up in my mazda handbook. It said to have the brakes checked right away. I took to my mechanic who has been working on my car for years and I trust him. He told me it was the dsc module and it would need to be taken to the dealer. He also told me it would be an expensive repair. I contacted my local dealer and will now be charged $150 for them to tell me the same thing my mechanic did. I did some research and found this to be a safety issue that many other mazda owners have complained about. I think this is unfair to us that no recall has been done or that this repair is so expensive. I have taken very good car of my vehicle and now I don't have the money to pay for this expensive repair.

I just bought my dtr a 2010 that has the same spongy brake problem I've read a lot about online. The pedal gives very little resistance (and there is virtually no braking) for the first 1-2" of travel, then it works and brakes normally. I tried trying to activate the ABS many times as some mentioned had "fixed" the problem for them but that made no difference. Not only did it not fix it, but it made me realize that the ABS doesn't work since at least 1 tire locked up and was skidding. So spongy brakes, no ABS, and no ABS warning light. I see many complaints about this (some say a new ABS and brake booster for $2k took care of it, but others said it didn't), and someone says there's even a tsb for it. So obviously it's a manufacturing problem, but mazda apparently won't do anything without getting $$.
