I can be turning left from a full stop and a few times almost went up onto the median seperating traffic. The car doesn't keep straight in it's own lane unless i put a lot of pressure with both hands on steering wheel and that doesn't always keep it straight, it veers left and right going down the road. Tire pressure light keeps coming on. when backing up hear like a grinding sound in passenger front tire. I bought this used at a Ford car dealership in June 2021. thats all i can think of right now. This has happened more than once no just one time.

my power steering has randomly failed for a second time. It happened once before as I pulled into a store -this time it happened while I was travelling southbound on highway 1 a very curvy road with steep cliffs where the speed limit is 55 so it was very scary when my steering suddenly went to manual steering. Turning the car off and waiting a few minutes seemed to remedy it. I continued to have a check engine light which cleared the next time I turned the car off. The power steering pump is an electric hydraulic pump so no belts involved. No weird noises just sudden scary failure. I researched on Mazda forums and found quite a few others with similar complaints and having spent money on dealers with no resolution. The car has 65k on it. The mfr does not have a change cycle for the fluid and I have verified the fluid clean. I did install a new battery and cleaned the ground on the terminal for the power steering pump as it seemed to help someone else. Mazda of course wants to take it and charge me to diagnose but based on other experiences with the dealer i do not trust them. Here is another person's similar story https://www.mazda3revolution.com/threads/power-steering-failure.108977/#post-1439705

MORE THAT ONE PROBLEM WITH THIS VEHICLE. 1) IT STARTS HONKING WHILE DRIVING, INSTRUMENT PANEL AND INTERIOR LIGHTS FLASH ON AND OFF, THE CAR WILL ONLY MAKE RIGHT TURNS AND WILL NOT RESTART WHEN VEHICLE IS TURNED OFF. YESTERDAY, IT DID IT ONCE AGAIN IMMEDIATELY AS I TURNED RIGHT ONTO THE CITY STREET FROM A PARKING LOT. LUCKILY THERE WAS ANOTHER PARKING LOT ENTRANCE ON THE RIGHT, SO I PULLED IN, PARKED AND TURNED OFF THE VEHICLE. IT CONTINUED TO HONK, FLASH INTERIOR LIGHTS AND INSTRUMENT PANEL AND IGNITION WOULD NOT WORK NOR CRANK. I TRIED TO RESTART THE VEHICLE SEVERAL TIMES OVER A FIVE (5) MINUTES, WHEN IT FINALLY RESTARTED AND I WAS ABLE TO GET THE VEHICLE HOME WITHOUT IT HAPPENING AGAIN. THIS VEHICLE HAS DONE THIS SEVERAL TIMES AND IT WILL START HONKING IN THE MIDDLE OF THE NIGHT WHILE PARKED AND OFF FOR NO REASON. THERE ARE TIMES THAT AS QUICKLY AS IT STARTED HONKING IT WILL STOP, OTHER TIMES, I MUST GO ATTEMPT TO TURN VEHICLE ON AND EVENTUALLY IGNITION WILL CRANK AND ENGINE WILL START. I HAVE TAKEN IT TO MAZDA BUT THEY ARE NOT ABLE TO REPLICATE THE PROBLEM AND TELL ME THERE'S NOTHING THEY CAN DO. I AM WORRIED I WILL NOT BE ABLE TO TURN ONE OF THESE DAYS AND HIT SOMEONE AND GET HIT BY SOMEONE ELSE WHEN THE CAR DECIDES IT WON'T TURN LEFT. NOT TO MENTION IF THE CAR WILL NOT START WHILE I AM IN A BAD AREA AND BE HARMED WHILE WAITING FOR THE CAR TO STOP HONKING, FLASHING AND REFUSING TO CRANK AND START. 2) WHEN YOU PUT GEAR IN DRIVE, FROM EITHER PARK OR REVERSE, AND TAKE YOUR FOOT OFF THE BRAKE THE CAR ACCELERATES AND LUNGES FORWARD WITHOUT PRESSING THE GAS PEDDLE. THE FIRST TIME IT DID IT I ALMOST HIT A PARKED CAR! THANKFUL I ACTED QUICKLY AND REAPPLIED THE BRAKE. NOW I ALLOW ENOUGH SPACE, AS IF I DRIVING A TRUCK AND AM READY TO APPLY THE BRAKE. DEALERSHIP STATES NOTHING IS WRONG WITH IT. MAZDA NEEDS TO TAKE THESE MATTERS SERIOUSLY. BUT IT'S GOING BACK!!

THE HEADLIGHT HAVE BEEN FLICKERING SINCE A FEW MONTHS AFTER PURCHASING THE CAR, & IT CAUSES INADEQUATE ALTERNATOR OUTPUT, IT HAS ALSO CAUSED ISSUES WITH LOSING MY POWER STEERING. THE HEADLIGHT NOT ONLY FLICKER WHEN BREAKING, BUT HAVE GOTTEN TO THE POINT THEY WILL COMPLETELY GO OUT, & WILL ALSO FLICKER ALL INTERIOR LIGHTS WHEN BRAKING & TURNING THE WHEEL. I HAVE BEEN PULLED OVER DUE TO POLICE THINKING I AM FLASHING MY LIGHTS WHEN BREAKING, BUT WAS LUCKY TO BE ABLE TO SHOW THE POLICE OFFICER THE SERVICE BULLETIN 01-019/13 & HE LET ME GO WITH A WARNING & STRONGLY ADVISED ME TO GET IT FIXED. IT IS NOW TIME FOR MY CAR TO GO THROUGH INSPECTION, & IT WILL NOT PASS WITH THE LIGHTS FLICKERING & GOING COMPLETELY OUT. THE PROBLEM HAS ONLY CONTINUED GETTING WORSE TO THE POINT THE HEADLIGHT ARE GOING COMPLETELY OFF WHILE DRIVING DURING HOURS WHEN HEADLIGHTS ARE NEEDED. I HAVE LOST MY POWER STEERING MULTIPLE TIMES AFTER STARTING MY CAR AND BEGAN DRIVING, WITH A BRAND NEW BATTERY INSTALLED BY A MECHANIC, & WHEN I HAVE LOST POWER STEERING I HAVE ALMOST CRASHED INTO THE SIDE OF MY WORK OFFICE & HAVE HAD TO TRY PULLING OVER TO THE SIDE OF THE ROAD DUE TO LOSING POWER STEERING WHILE DRIVING. IT IS TIME FOR ACTION TO BE TAKEN & THIS BE A RECALL BEFORE SOMEONE IS KILLED, GMC CAN RECALL FOR THE SAME COMPUTER SYSTEM UPGRADE THAT IS NEEDED FOR MY MAZDA 3, BUT HAVE ONLY BEEN TOLD THAT IT IS NOT COVERED AND THAT I HAVE TO PAY OUT OF POCKET, WHICH I HAVE GOTTEN QUOTES FROM SEVERAL MAZDA DEALERS OVER THE SEVERAL YEARS I HAVE OWNED & CONTINUE TO DEAL WITH THE ISSUE AND IT WILL COST ME OVER $500 TO HAVE REPAIRED!! DUE TO NOT HAVING THE MONEY TO AFFORD TO COMPUTER UPGRADE WHICH I CONSIDER A HUGE SAFETY ISSUE THAT SHOULD BE MAZDA'S PROBLEM TO FIX BEFORE THEY HAVE A CLASS ACTION LAW SUIT BROUGHT AGAINST THEM, BECAUSE SOMEONE DRIVING A MAZDA 3 GET SERIOUSLY INJURED OR SERIOUS INJURE SOMEONE ELSE!

ABOUT A MONTH LATER THE CAR DID IT AGAIN BUT I WAS TRAVELING AT ABOUT 67 MILES AN HOUR, AND LOST POWER STEERING! THE LIGHT STAYED ON LONG ENOUGH FOR ME TO RECORD WHAT WHAT HAPPENING AND TO DRIVE TO THE DEALER. AGAIN THE LIGHT WENT OUT AS I ENTERED THE DEALERSHIP AND THEY SAID THERE WERENT ANY CODES ON THE CAR NOR WERE THERE ANY IN THE MEMORY. THIS IS DANGEROUS AS I WAS TURNING INTO THE DEALER, THE POWER STEERING TURNED BACK ON AND I ALMOST SPUN IN A DONUT BECAUSE I WAS TURNING THE WHEEL REALLY HARD DUE TO NO POWER AT THE TIME. ITS ANNOYING AND I WOULD REALLY LIKE TO HAVE IT FIXED BUT NOBODY CAN TELL ME WHAT IT IS!

MY CAR WAS T-BONE, IT SHOULD NOT HAVE BEEN DRIVEN. MY DAUGHTER WAS MADE TO DRIVE THE DAMAGED CAR HOME INSTEAD OF USING A TOW TRUCK TO TAKE IT TO THE NEAREST BODY SHOP. THE SUSPENSION WAS BENT COMPLETELY INWARDS (DOUGHNUT TIRE WAS USED TO DRIVE THE CAR HOME WITH A BENT SUSPENSION). I WAS TOLD BY THE INSURANCE COMPANY TO DRIVE THE CAR TO THE NEAREST SHOP THEY DO BUSINESS WITH, AND I DID. I ASKED THE SUPERVISOR/ADJUSTER TO TOTAL THE CAR BEFORE EVER SEEING THE INTERNAL DAMAGE. I KNEW THE CAR COULD NOT BE REPAIRED BACK TO THE WAY IT WAS, ALMOST NEW CONDITION. WE WENT BACK AND FORWARD ABOUT TOTALING THE CAR. HE REFUSED TO TOTAL ONLY AFTER PLEADING WITH HIM, HE AGREED TO DO SO. AFTER SEEING THE CAR STRIPPED FROM LID OF TRUNK, TIRES OFF, I SAW THE RIGHT TIRE COMPLETELY BENT INWARD. I WAS TOLD IT WAS SUPPOSED TO BE THAT WAY. I TOLD THE ADJUSTER I DID NOT WANT THE CAR THAT IT IS DESTROYED, AGAIN I ASKED HIM TO TOTAL THE CAR. HE SAID NO, THE CAR COULD BE REPAIRED. I WAS ASSURED BY THE BODY SHOP OWNER THAT HE WOULD REPAIR IT BACK 100%. HE DID NOT. THE SHOP KEPT MY CAR APPROX. 2 MONTHS FROM THE 15 DAYS PROMISED TO BE FIXED. I PICKED UP THE CAR ON 6/24/15. MY DAUGHTER AND I EXAMINED IT AND THE BACK SEAT PULLED AWAY FROM THE BACK AND BASE OF THE SEAT; WOULD NOT STAY LOCKED DOWN. IT PULLED COMPLETELY AWAY FROM THE BACK, OUT, AND UP; TAIL LIGHTS DID NOT WORK; SUSPENSION WAS UNBALANCED, THE CAR PULLED LEFT. THE RIGHT SUSPENSION WAS LOWER ABOUT 5/8" LOWER THAN THE LEFT SUSPENSION; NAIL IN TIRE WHICH MADE THE TIRE SENSOR LIGHT STAY ON; CAR SMELLED OFFER INSIDE; IT WAS NOT WASHED BEFORE GIVEN BACK TO ME; PAINT HAD DRIPPED AND DRIED UP AT THE BASE OF THE CAR WHERE REPAIR WORK HAD BEEN DONE; RIGHT DOOR DID NOT ALIGN; BACK PANEL DID NOT ALIGN; SUSPENSION WAS NOT COATED, LEFT TO RUST OUT; RADIO HAD BEEPING SOUND WHEN CHANGING STATIONS; MY DAUGHTER HAS 13 MONTH OLD WHO RIDES IN THE CAR.

EA21002 · Desiccated Air Bag Inflator Rupture

Opened Sep 17, 2021 · No close date supplied

Status: open (inferred from source dates) · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger Side:inflator Module

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 www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, 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 nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.
