Exterior lighting: fog lightsReported June 5, 2003 · 64,000 vehicles affected
What is wrong
On certain mini vans and passenger vehicles, the socket holder in the fog lights is installed in the lamp casing using pressure. During operation of the fog light, the heat from the bulb can expand the socket holder. The expansion can force the socket holder rearward. After repeatedly being subject to this expansion, if the fog light is also subjected to vibration during vehicle operation, the socket holder with the bulb holder and the wiring harness may separate from the fog light casing.
Risk
Should this occur, the bulb socket and the harness can drop inside the bumper and possibly but rarely, the heat generated by the bulb can cause the bumper to burn.
Remedy
Dealers will install a spring to prevent the socket holder from separating from the lamp case. Owner notification began on july 14, 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact mazda at 1‑800‑222‑5500.

Desiccated Air Bag Inflator RuptureOpened September 17, 2021, still open

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

Air Bag Inflator RuptureOpened February 24, 2015, still open

The Office of Defects Investigation (ODI) opened PE14-016 in June 2014 based on six inflator rupture incidents involving consumer owned vehicles produced by five vehicle manufacturers.All six vehicles were operated in Florida or Puerto Rico at the time of the rupture and for the majority of their service life, and were equipped with inflators produced by Takata, a tier-one supplier of automotive air bag systems.During the course of PE14-016, ODI determined that five additional vehicle manufacturers used inflators of a similar design and vintage also supplied by Takata. No evidence of field failures was found in vehicles produced by these five additional manufacturers.Nonetheless, at ODI's insistence, all 10 vehicle manufacturers initiated a regional recall within approximately two weeks of the opening of the investigation.The regions recalled initially included Florida, Puerto Rico, Hawaii, and the U.S. Virgin Islands, areas with high absolute humidity and climatic conditions believed to be a significant factor in the inflator ruptures.As part of the recall actions, inflators removed from remedied vehicles are to be returned to Takata for testing.Takata's initial test results on passenger inflators from remedied vehicles indicated a much higher than anticipated rupture frequency for inflators returned from Florida.Accordingly ODI requested all 10 manufacturers expand the regional recalls for passenger inflators to include other geographic areas where high absolute humidity conditions exist, including the Gulf States and other coastal areas.Takata's testing of the passenger inflators to date continues to indicate this geographic area as having the highest risk, with no ruptures occurring from inflators returned from outside the expanded recall regions.During PE14-016 four additional passenger inflator field events occurred, all in vehicles from the same expanded geographic region.Also during PE14-016 four additional driver inflator field events occurred including two in vehicles from regions not known for high absolute humidity, specifically California and North Carolina.Accordingly, ODI requested all five of the affected vehicle manufacturers currently using the subject Takata driver inflators expand to nationwide recalls.Significantly, neither of the affected vehicle manufacturers or Takata provided any explanation to account for these two driver air bag inflator ruptures outside the area of high absolute humidity.Takata testing of returned driver inflators indicates a lower rupture frequency as compared to passenger inflator testing.All test ruptures reported by Takata to date have occurred on inflators returned from high absolute humidity areas.The investigation now includes all manufacturers and vehicles known to be affected at this time.ODI's investigation will focus on, among other things, root cause analysis, other potential defect consequences, identification of affected vehicles scope, and adequacy of the remedy.The five ODI reports cited above can be reviewed online at http://www-odi.the federal safety agency.dot.gov/owners/Searchreference under the following identification numbers: 10537899, 10568848, 10585224, 10605877, 10651492

When I take my foot off the gas it stays at the same speed or it speeds up on its own. When I press on the break sometimes it feels like it's not going to stop and just keep going or it jerks forward when I stop. This happens when I am driving on the road and the cruise control is not on when this happens.

After two years of driving this car the clutch pedal assembly completely broke puncturing through the fire wall and brake reservoir, luckily I was starting the vehicle in a hospital parking lot when I pushed the clutch in it went completely to the floor and did not come back up. It was completely inoperable, I had to have the car towed after patching the firewall and replacing the clutch pedal assembly for $1800 I was told that part was faulty on this vehicle and if it happened once it would probably happen again. One year later it broke again only this time I was driving down the road when I went to shift gears the clutch went to the floor and didn't come back up, I had to pull over luckily I didn't get hit or cause an accident. I was told by mazda there would be no recall because this part isn't a direct safety issue.

Filed Aug 21, 2017 · Acceleration, Engine · CA

2003 mazda6 model cars were built with faulty throttle bodies. Unaware of this, I bought one of these vehicles and immediately began experiencing issues with it. When driving very slowly, under 15 MPH, the car will suddenly throttle, accelerating it in bursts even when applying the brakes. That issue is problematic but relatively minor; however, there is a much more dangerous issue the faulty throttle body creates. When driving at any speed, the faulty throttle body can cause the engine to cut out without warning. My wife was driving with our kids in the car the first time we had the engine cut out while driving (soon after purchasing the car). Luckily, she was driving in a residential area at 25 MPH. The engine has cut out on me while driving 65 MPH on the freeway. I was forced to coast through freeway traffic to the shoulder in order to stop the car and restart the engine. The engine has cut out, without warning, at several speeds. There is no rhyme to when it will cut out and no indication it's going to cut out ahead of time. I spent over $500 trying to solve the problem with mechanics unsure what was wrong. Then a mechanic happened to have an old service bulletin (sb), dated 5/18/2006, from mazda that stated throttle bodies with the markings aa, ab, or ba at the end of their serial numbers (as is the case with the one in my car) are "no good". Because the part is labeled "no good" under mazda letterhead, I figured there must have been a recall issued before I owned the car that the previous owner somehow missed. I took the car in to a mazda dealership where I was assured no recall has ever been issued on the part and in order to replace it, the cost will be over $1,000. A recall must be made on this extremely dangerous and faulty, by mazda's own admission, part before unsuspecting people are injured or killed, if that hasn't happened already.
