Service Brakes Problems of Mazda CX-5 - part 1

The vehicle's automatic emergency braking (aeb) / Smart brake support system intermittently triggers "false positive" emergency braking events during critical driving maneuvers, specifically while accelerating to merge into highway traffic. During these events, the system violently applies the brakes with no external hazard present. Crucially, the vehicle fails to acknowledge driver override input. Depressing the accelerator pedal fully does not disengage the automatic braking, stripping the driver of vehicle control and exposing the vehicle to a severe risk of being rear-ended at high speed. Simultaneously, the vehicle experiences a persistent "in-unit telematics malfunction" error on the dashboard, accompanied by rapid-fire mobile app notifications (14 alerts in a single day) stating "critical vehicle malfunction: vehicle cannot be driven. " these communication module errors have persisted despite the dealership applying Mazda's latest software updates, indicating a critical network failure or hardware defect that compromises active safety systems.

The contact owns a 2025 . The contact was in a parking lot of a shopping center, put the car in gear and the steering wheel became inoperable , vehicle would not stop while depressing the brakes. Four additional vehicles were damaged from the impact with one vehicle deemed a total loss. The right front end was impacted including the hood and the right wheel. No additional property damage. The vehicle came to a stop in the parking lot from impacting the vehicles. Both front driver and passenger side air bags deployed. The vehicle was towed to a tow yard. The vehicle was deemed as a total loss by the insurance company. The contact sustained injuries left broken clavicle, left arm, left and right knees received lacerations and lacerations and 3 broken ribs on the left side and hematoma and received medical treatment at the emergency room intensive care. A woman in the back seat of one of the parked vehicles sustained minor injuries and received medical treatment. The dealer nor manufacturer was notified of the failure. The failure mileage was 2,837.

Brake pedals do not have enough pedal reserve, it takes some time for it to come to a stop. The brakes don’t feel secure. We feel like the brakes are going to give up. It also makes a very loud scratching sound when reversing and pressing on the brakes.

2021 Mazda cx5 awd- non turbo engine. Sunny day, dry. My car was clean. No precipitation. Some shadows of the interstate light poles across the road 200-300 feet in front of me, but they were thin shadows. Sun was to my left. I was driving south on may 01 2026 about 10am on the interstate going highway speeds, with adaptive cruise control "on", in the 2nd lane of a 4 lane interstate. Thankfully no other traffic ahead or behind me. Car slammed on the brakes suddenly, pretty hard. I counteracted and added more gas pedal to keep in going. I turned off the cruise control. After a while I re-engaged the cruise control and had no issues. This could have been a huge accident in busier traffic. Will get the car checked out at Mazda dealership service this week.

Unintended acceleration incident. I entered the parking lot of a business where the salvation army is located to drop off a donation. The parking spaces were on the left side. As I pulled into a parking space and was in the process of parking, the vehicle suddenly lurched/accelerated forward unexpectedly and struck the concrete wall of the building. The airbags did not deploy despite the frontal impact. No one was seriously injured, but my husband, daughter, and I experienced soreness the following day from the impact. Thankfully, I had chosen a parking space in front of a concrete wall rather than the glass storefront windows, which could have resulted in far more serious injuries or damage. I contacted my insurance company, and the vehicle has since been repaired.

The vehicle exhibits unintended acceleration behavior when the brake pedal is applied. Instead of slowing down, the engine revs and the vehicle does not decelerate as expected. On March 16, 2026, while merging onto a highway and applying the brakes, the engine suddenly revved to approximately 3,500 rpms while the vehicle failed to slow down. There have been previous issues with the vehicle not slowing when breaks are being applied, nut this is the first instance when it was noticed that the rpms increased while breaking. This issue has also been reported to the dealership, with service documentation noting that when applying the brakes, the engine revs and the vehicle does not slow or accelerate properly. This creates a dangerous condition where braking input does not result in expected deceleration and may instead cause acceleration-related behavior. The issue has not been resolved. This issue significantly increases the risk of collision and loss of vehicle control.

Incident description: on multiple occasions in January and February 2026, while operating a 2024 Mazda Cx-5 in reverse on low-friction surfaces (snow/ice) with a slight incline, the vehicle suffered a total systemic failure. System failures: while reversing at low speeds, the engine spontaneously shut off without warning. This resulted in an immediate loss of power braking and power steering. Simultaneously, the electronic gear selector (shifter) became non-functional, preventing the vehicle from being placed into 'park' to stop the uncontrolled rearward slide. Safety risk: the vehicle became a "runaway" object on several occasions. In one instance, the vehicle narrowly avoided crushing a pedestrian against another parked car, stopping only when the tires reached a different surface texture. In a separate incident, the vehicle slid uncontrolled down a residential hill, striking snowbanks. There is a grave concern regarding whether the supplemental restraint system (airbags) remains functional during these engine-stall events, as the dealer could not confirm occupant protection status during a total power loss. Inspection & reproduction: the vehicle was presented to an authorized Mazda dealer on March 3, 2026. The service department attempted to replicate the issue by reversing over soapy water on a gravel surface. However, due to the high friction of the gravel, they were unable to induce the specific tire-slip/low-traction conditions required to trigger the malfunction. No error codes were found during an informal scan, and no warning lamps or messages appeared prior to or during the failures. Component for inspection: the vehicle is available for inspection. I believe the failure is rooted in the traction control or engine management software, which appears to improperly shut down the powertrain when it detects specific wheel-spin patterns in reverse, subsequently disabling critical safety systems including brakes and transmission locks.

Breaks and gas pedal simultaneously stopped working while driving and steering wheel locked up.

The Smart brake support system malfunctioned while driving. The vehicle began shaking and lost power, requiring excessive throttle to move. The car hesitates and may not accelerate normally, creating a dangerous situation in traffic. Warning lights appeared on the dashboard and the vehicle became unsafe to operate. The issue occurred shortly after purchase and was reproduced multiple times. The dealer inspected the vehicle but refused to provide a written diagnosis or repair timeline. The vehicle is unreliable and poses a risk of sudden loss of control or rear-end collision.

The contact leased a 2024 Mazda Cx-5. The contact stated that the yellow electronic emergency brake light was displayed. The cruise control and rear brakes were inoperable. The brake pedal was pulsating while depressed. There was smoke coming from the front brakes. The vehicle was taken to a local dealer, who replaced the brakes, and the module was inoperable, but the failure recurred. The vehicle was taken to three independent mechanics, who determined that the rear brakes were firm. The manufacturer was contacted, and a case was opened. The failure mileage was approximately 24,000.

My wife's vehicle has a "infotainment screen" (dashboard touch screen). There is a class action suit (csp13d dealer letter) for issues regarding the screen performing tasks (ghost screening touch) on its own. In lieu of a Mazda vehicle mass recall, they agreed to "fix" the issue with a software update and replace the cmu module of the vehicle to rectify this issue. I am here to report / advise you that many Mazda owners are not happy and have taken it upon themselves to disconnect these screens and do other "work around self repairs (removing/ disabling the unit) in order to fix the issues that occur. I have directly contacted Mazda in regards to my issues and they stat they can only do what was advised on the court ordered settlement and nothing more to fix the issue. I want to advise you first hand, their fix for this issue does not fix the problems. In fact, it is making it much worse! now my wife's vehicle is operating this screen by itself, while driving, creating a major distraction. This "ghost touching" is actually going into the braking system settings and trying to change/ alter them as she is driving! a major safety issue. She has had to, on several occasions, pull over /off the road, shut down the vehicle and try to "reset" what has occurred and check her system for any altered setting. . If possible. As a retired police officer, I can tell you first had that if we ever encountered such thing/ safety issues reported by drivers, we would not allow them to travel any further with the vehicle and have it safely towed to a dealer or mechanic for repair. For their safety as well as the rest of the publics safety!! Mazda has refused to fully fix this issue and you can even see on numerous social media posts of many others reporting similar issues, disabling their devices on their own and doing other work arounds to mute or disable their devices totally. I implore you to do a full recall of all affected vehicles to fix the problem ASAP!.

While driving on the highway in traffic, I was applying the brakes (slowly and smoothly) and moving with the flow of traffic when the sbs system activated the brakes harshly and slammed me to a stop without reason. In addition to throwing me forward against my seatbelt, it also resulted in the car behind me rear-ending me. I did not hit the car ahead of me, since I was far enough behind them before the Smart brake support engaged, but the feature caused an accident that could have been avoided.

What component or system failed or malfunctioned, and is it available for inspection upon request? - Smart brake support (sbs) & forward obstruction warning system malfunctioned. Front radar sensor malfunctioned. Parking brake malfunctioned. I-activesense system malfunctioned. Emergency lane keep disabled. Dynamic stability control malfunctioned. Traction control system not operating correctly. Anti-lock brake system (abs) malfunctioned. Brake system not responding. How was your safety or the safety of others put at risk? in total 10 malfunctions led to brake not responding and could not stop the car and resulted into a car accident. Has the problem been reproduced or confirmed by a dealer or independent service center? no has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? police report from car accident states brake malfunction. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? car was totally fine until all 10 error messages appeared on Jan. 17th 2026 12:42-12:43pm and immediately the brake system did not respond and resulted in the car accident. **important** police report documented that the officer on scene is a witness of the car dashboard shows “brake malfunction”.

While driving at various speeds, including highway speeds, the vehicle intermittently fails to slow down when the brake pedal is applied. On multiple occasions, the brake pedal was pressed but the vehicle did not respond appropriately and continued moving forward. On December 1, 2025, while traveling at approximately 65 mph on the interstate in rainy conditions, the vehicle began making a grinding sound and started sliding instead of slowing down. The vehicle briefly lost the ability to decelerate, creating a near-collision with a semi-truck. On December 22, 2025, the issue occurred twice in one day. While attempting to brake at a stop sign and in traffic, the vehicle did not slow down, nearly causing collisions with vehicles in front and adjacent lanes. In the instance where approaching the stop sign where a vehicle was stopped, the dashboard flashed “break” while I was breaking as hard as I could. Warning lights and sensor-related alerts have appeared intermittently prior to and during some incidents. The issue has continued intermittently, including additional incidents where the brakes were either unresponsive or overly sensitive. They do not respond in a consistent or predictable manner, making safe driving nearly impossible. This problem places myself and others at significant risk of collision due to loss of braking control. The vehicle has been taken to multiple dealerships for inspection. The problem has not been successfully replicated, and no repairs have been performed to resolve the issue. Dealership documentation includes customer reports of “not braking” and brake malfunction concerns.

Brake rotors on all four wheels measured below minimum thickness specification at only 17,000 miles, requiring complete replacement of all rotors and pads. Rotors replaced at koch Mazda (easton, PA) on January 7, 2026 and no longer available for inspection. Safety risk: rotors below minimum spec have reduced structural integrity and heat dissipation capacity, creating risk of warping, cracking, or failure during emergency braking or sustained braking. Under-spec rotors can cause brake fade, increased stopping distances, and potential catastrophic failure. At 17,000 miles, this represents premature failure of a critical safety system. Dealer confirmation: koch Mazda initially charged $89. 99 for diagnostics claiming "nothing wrong" despite customer providing TSB 04-003/24 documentation. After formal complaint, dealership measured rotors below minimum spec and replaced all four rotors and pads as "non-warranty goodwill repair" (value $1,184. 97). Calling it "goodwill" rather than warranty avoids documenting as defect claim. Dealership stated Mazda corporate approved the goodwill repair, indicating manufacturer awareness of widespread defect being managed case-by-case rather than through recall. Warning symptoms: popping/clicking noise when first moving forward or reverse after sitting idle. This symptom is specifically described in Mazda TSB 04-003/24 as caused by deteriorated grease between brake pads and shims. Systemic pattern: research reveals hundreds of similar complaints across 2013-2025 Cx-5 model years involving premature rotor/pad failure at 11,000-35,000 miles. TSB 04-003/24 addresses this exact pattern across multiple model years, confirming manufacturer awareness. Normal rotor life is 50,000-70,000 miles; failure at 17,000 miles suggests manufacturing defect, improper heat treatment, or design flaw affecting entire Cx-5 brake system across 12+ model years.

At stop signs, in a row of 3 or 4 cars, on the 3rd or 4th stop, I apply the brake but it accelerates as I am braking, moving forward 8 or 10 feet. Over the course of 1800 miles, this has occurred 3 or 4 times, narrowly avoiding collisions.

The contact owns a 2021 Mazda Cx-5. The contact stated that the front brake system malfunction, forward brake malfunction, and check engine warning lights were illuminated. The contact stated that while driving at various speeds, the vehicle started jerking and hesitating as if the wheels would lock up. The steering wheel vibrated while turning to the left or the right. The vehicle was taken to the dealer, who was able to retrieve a diagnostic code; however, the dtc number was unknown. The dealer was unable to identify the exact cause of the code. The vehicle was not repaired. The manufacturer was informed of the failure and opened a case. The failure mileage was approximately 81,000.

After driving a few mile, the following two warnings come up * Smart brake system malfunction * forward radar sensor system malfunction. If I turn off the car and then restart, the warnings go away. However, it comes back if I drive for a while again. I have visited dealership a few times for the same issue, they replaced the wheel bearing and brake switch. The warning disappeared for days and came back.

I pulled the car into garage, and realized it's not inside enough. So I moved the car forward, but forgot to place the shift to p position. With the shift in d position, I shut off the engine, opened the door, ready to get out. I did not notice the car was moving backward, until the open door hit the garage frame. I file a claim with my insurance, had the front door replaced in a local body shop. I confirmed that in d position, with engine shut off, the car can move freely in my drive way. I did have this issue in my other two cars, I occasionally forgot put the shift from d position to p position, but the car did not move. This issue - a car can move freely without driver's awareness - is a serious and dangerous issue. If this happens in the street, a serious crash can occur. The car manufacturer should figure a way to prevent this from happening when the shift is in d position and engine is shut off.

The car has a lot of vibration when driving 60mph and above. Have had this issue looked at more than 5 times and they had my card for 1 month at the dealership trying to find the issue. This started back in February of 2024 and I have purchased 4 sets of tires and nothing makes the vibrations of the seat, steering wheel go away. Originally it wasn’t vibrating while driving back in February of 2025 only when braking to which I said to them I think it’s the rotors that have an issue. They never check the rotors and said it was my tires that were cupped. I put new tires on the car and still the same issue and went back to the dealership in April of 2024 and let them know it think it’s the rotors. In fact it was the rotors they were warped and they balanced the tires again. The dealership recommended resurfacing the rotors to which I had done. A couple of months later the vibration while driving started. Bought another set of tires had then installed, balanced and aligned and still vibration. I thought maybe it’s the brand so I bought another set of tires to which the problem is still there. Now besides the vibration while driving I have vibrations while braking again after the dealership put in new rotors back in Nov. 2024. When to the dealership on 06. 26. 25 let them know the vibration while braking is happening again and I think it’s the rotors. They check them and rotors are warped again about only 6. 5 months. The service manager said she will resurface them for me for no charge but then the service advisor said if they do that that the resurfacing is going to make me have to change the brake pads as I will end up in the red since my brake pads are in the yellow right now. I said then don’t resurface because I am not paying for the brake pads when that should’ve been done the first time the rotors were warped. I feel like I risk my life everyday driving this car to work 34miles one way.

From my service mechanic. . . "rear brakes at 8mm/8mm on the right side, but 4mm/6mm on the left. These brakes were replaced 1500 miles ago and should not be showing this kind of wear. Examined brake pads, found evidence of overheating. Scanned vehicle, confirmed no codes from electronic parking brake. Actuated parking brake and confirmed it is engaging and releasing as commanded. Found a technical service bulletin related to parking brake drag on this vehicle. The brake pad damage pattern is consistent with what we observed today. Mazda recommends replacing the affect caliper(s) with an updated version to address this issue. Confirmed by lot number that current calipers are older version. TSB attached. Recommend replacing calipers and rear brake materials. ".

I bought this 2020 Mazda Cx-5 sport 2. 5l all wheel drive from a big dealership on July 31, 2023. I started having issues with epb (electronic parking brakes) in February 2024. When I put the e-brakes on, the yellow parking brake light and the red brake light would come on. Seems like they would engage and disengage just fine except those 2 lights would stay on no matter how many times I tried turning the e-brakes off. I put a new battery in because of some research I did to no avail. Tried putting it in service mode then taking it off service mode. . . . . . Which did work for a couple of months. Then the problem reappeared and the two lights came back on. Sometimes you hear the e-brakes retracting on the rear right side only. And you can smell the brakes from heating up. On 2/26/2025 after getting out of work, I got in my car, turned it on and boom the brake lights are on again. I tried to drive and noticed the e-brakes were engaged. I didn't do it because I don't use the e-brakes at all for fear it would get stuck on and leave me stranded. I have been dealing with this for months and I am so frustrated. This car is only 5 years old. It shouldn't be having e-brakes issues. I've been doing a lot of research and found out that a lot of Mazda owners are having this very same problem. Mazda is very aware of this issue and has known about it for some time, but refuses to do a recall. I’m afraid to drive the car for fear that the e-brakes would engage while I'm driving in the highway and cause me to have an accident. This is a safety issue that needs to be addressed. I don't know what else to do. One thing I do know. . . . . . If Mazda doesn't fix this issue, I will never buy a Mazda again and make sure my kids never buy a Mazda either.

Good afternoon. I am reporting an incident that occurred on December 29, 2024. I was driving my 2019 Mazda Cx-5 and I was about to make a left turn. However, as I was making the left turn, I received a notification on my dashboard about a "forward Smart city brake support malfunction" (a photo of the notification will be included). My car instantly lost control and it did not stop until it collided with the street curb of the road I was attempting to turn on. Fortunately for those around me, my car did not collide with any other vehicles on the road. However, this collision caused damage to the right side of the vehicle, as the right airbag of the vehicle had deployed. I believe that this is a very significant problem that should be looked into as soon as possible. If my car were to hit other drivers on the road, it could have led to a very tragic incident. As far as repairs go, I wanted to wait and see how this complaint would carry out. I do not believe that it would be fair for me to pay repairs for an event that was out of my control. Thank you.

The steering and braking systems on my vehicle malfunctioned after jumping my vehicle when the battery drained too far to start, or even power my cars baseline electrical systems. After jumping my car, I started backing out of my parking spot and when I turned the wheel it very violently jerked in a manner that could have hurt me if I'd been holding onto the wheel tighter. Around this same time I believe I recall the brakes automatically applying and halting the vehicle. I was too far out of my parking spot when this began occurring and had to try to maneuver into a different one, during this attempt both of the conditions described above reoccured several times. I eventually noticed that it only seemed to trigger when the wheel was at more extreme steering angles, by keeping the steering angle lower I was eventually able to maneuver into another spot without triggering the issues. After parking and letting the car run for a bit to recharge the battery I no longer experienced these issues. There were several warning lights related to roll stability control, lane departure monitoring before pulling out. The following warnings were present, but I'm unable to recall whether they displayed before I first hit the issues: Smart braking malfunction, power steering malfunction, transmission malfunction, check engine light. The vehicle has not yet been inspected by anyone, however I was able to find evidence of other people complaining about what sounds to be the same issue going back several years online. [xxx] [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The vehicle accelerated on its own, while I was parking. My foot was on the brake when the vehicle just took off. It continued to accelerate until a building stopped it. I continued to brake but the vehicle did not stop. Once the vehicle collided with building, saw on the digital read out the "brake system malfunction" and then camera malfunction. The vehicle was towed from the site and the insurance adjuster has sent me word that the vehicle is a total loss.

On [xxx], I was the operator of a 2019 Mazda Cx-5 in los angeles, California. I parked the vehicle on an incline on or around [xxx] in los angeles, California, and then exited the vehicle. The vehicle remained stationary for some time, until it suddenly began rolling backwards at a speed that pushed me to the ground while I was getting my things from the passenger side door, causing me serious injuries. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While driving through town the braking system malfunctioned and the car came to a stop in the middle of the road with messages on dash saying the Smart city braking support was malfunctioning as well as brake assist. Engine light came on as well as traction control light right after the car coming to a sudden hard braking stop. Drove straight to shop to check engine code which was p0882. I am so afraid of this happening on the highway with my daughter in the car. There is a recall for this system but my car isn’t under the recall so I'm sure there are others that are having the issue but aren’t covered under the recall either.

After having brakes serviced brake lights continue to come on. After research from many other complaints they are saying it’s the emergency parking that needs replaced? we shouldn’t have to replace this every time the brakes are replaced.

The most recent incident: driving 35 mph on a 4 lane divided boulevard, vehicle 5-6 car lengths in front of me indicates intention to turn right. No traffic in lane to my left should I need to change lanes. I continue to coast. At approximately 2-3 car lengths, the vehicle in front has nearly completed the right turn - there is no risk of collision - but my car brakes hard. This is the 4th time my car has activated emegency braking in a situation it is not warranted. I have been dirving for 36 years with no accident. I do not need nor want this technology as it is more prone to causing accidents than preventing them. Additionally, the car throttle response is slow to recover in these situations, so while I mashed the acclerator to the floor to avoid being rear-ended - the car did not accelerate for 1-2 seconds (rpm went up, but the engine did not engage for several seconds). In situations where aeb might have been marginally helpful, detecting cross traffic running red lights, the car has never detected this - and thankfully I'm an experienced driver so aeb was not needed. This technology, imo, is not safe and will lead to over-reliance causing more accidents in the future.

Something malfunctioned with the brake system of the car. The car was in park and off. I exited the car, reached back into the car for an item, and shut the door. I then walked up the driveway and to the front door. At that point, the car began to roll down the driveway. Someone coming down the road in front of the driveway hit it on the front passenger side. The car then continued to roll across the street and part way up the driveway across the street, coming back across the street and then ran into the same car that hit it. I was then able to open the car door and get inside. It was still off and in park. I depressed the brake pedal, started the car, put it into drive, and moved it to the side of the street. After the incident, I tried multiple times to replicate the incident with my car. I tried leaving it in reverse, even though I know it was off and parked. I also tried leaving it in neutral and turning it off, even though I know it was off and in park. Each time, the car began to roll immediately. There was no way that I could have done what I did that day, which was to step out, reach back in to get a bag, shut the door, and then walk away. The car was definitely off and parked when it happened. The vehicle is currently at a Mazda authorized repair shop, and I am awaiting the final word on whether or not they can detect what exactly caused the brakes to malfunction. There were no warning lamps or messages prior to the issue; however, I did notice that something seemed to be going on with the screen of the car prior to the incident. Though the clock was set to the correct time, the screens auto-sensor for day and night mode was not functioning correctly. (when it got dark, the screen was still staying lit up brightly. I confirmed that it was on "auto" mode, and it should have dimmed since it was after 9:30pm and dark out, but it didn't. I had to manually switch it to "night" each time it was dark. ).

Back brakes arent gripping, caliper isn’t working been changed quite a few times. Either the abs or electric brakes.

I was waiting at a traffic signal to make a left turn, with my foot on the brake. The car accelerated aggressively, with no warning, like the pedal was pushed to the floor. I stood on the brake and shoved the shifter into park - coming to a stop in the middle of the intersection, fortunately my wheels were pointed straight and the car did not race into oncoming traffic. My 96 year old father was in the car with me. Thankfully, my grandchildren were not in the car. You could smell the gas and brakes. It was not driver foot placement, nor was it floor mats. Vehicle has ~ 75k miles, and I am terrified of this happening again. I had driven this car regularly in rush hour stop & go traffic for years with no event like this ever before. Apparently sudden unintended vehicle acceleration is a recognized problem.

I had coplained about a long, soft brake pedal on 10 February 2024 to hiley fort worth motorcars and got a report on 13 February 2024 stated that after inspection, they could not duplicate my complaint, so they did a visual inspection and washed the car!!!! today, 29 may 2024, I had to make an emergency stop and pressed the brake pedal to the floor! the abs came on, but the brake pedal should never reach the floor. The other car had stopped and I swerved out of the way. No warning lights came on nor sounds. Additional information; if the brakes are applied by the adaptive cruise control, and you step on the brake pedal after the brakes have been applied automatically, the brake pedal is nice and firm, like it should be. But if there is no intervention with the car, the brake pedal is very long and soft.

I was near a red light and applied the brakes, but the car accelerated and ran into the truck stopped in front of me. This happened around may of 2024. I took the car to the elk grove Mazda dealer. They ran diagnostic and road tests but found nothing wrong. The car had the same problem again sometime later inside my garage. The car rammed into the drywall while I tried to stop by pressing the brake pedal. I took the car to the aaa repair shop in August 2024. They spent three days, and they told me they found a problem with the "steering angle sensor. " it was 22 degrees off calibration. They reset the sensor, and the car ran better. However, the car acted again after some driving. It tries to accelerate while I apply the brake pedal near a stop. I took the car back to the aaa shop, but they did not find any problems in a whole week. I still drive this(my only) car, but extra careful, keeping a longer distance between cars in front of me and braking ahead few times ahead of any stop.
