Vehicle Speed Control Problems of Mazda CX-7

Upon putting my car in reverse with my foot on the break, the vehicle accelerates to the point I have to smash the break to the floor. This has happened several times while putting my car in drive and while waiting at red lights. I've almost been in several accidents because of this issue. It has been happening since I purchased the vehicle new. The dealer was unable to duplicate the problem so they decided the car was fine.

On 4 separate occasions, the brakes failed to stop the car. The last 2 times, the car not only didn't stop but it accelerated. I could have been involved in a couple of very serious accidents. Each time, I was driving on city streets on dry pavement. The last occurrence was on Aug 14, 2017, and I tried to stop the car by using the gear shift, but the car didn't stop right away. The dealership is currently working with Mazda tech support, but they can't find a cause for this. They want to install a flight recorder, and for me to take the car back so I can drive it until this happens again. I told them no because of the seriousness of the problem, and the dealership is testing it now. This problem began in August 2015, and I've already spent over $1000 on repairs related to it.

I lost power to my 2010 Mazda cx7 while going 60 mp downhill in a mountain pass. My car went from 60 mp to 40 mp in about 30 seconds. I immediately pulled over as black smoke poured out of my tail pipe and had the car towed. My mechanic said the turbo was blown, which cause the car's oil to completely burn up, causing damage to the timing chain and engine. All of the oil was gone in a matter of a few miles. The car had been up to date on all maintenance. A new turbo and engine was needed on a car that had 74,000 miles on it.

Car accelerates when idling in drive or reverse even with foot on brake. Causes many near accidents when parking or idling. Seems to be connected with ac compressor. This is very dangerous and should be recalled and fixed.

I was driving at a normal rate of speed on a fairly busy street when the car just suddenly decelerated, causing the car behind me to swerve to narrowly avoid me. Thankfully he also avoided hitting anyone else. My car continued to move forward, but with no ability to accelerate. I managed to get clear of traffic and was able to get the car to a repair place nearby. I was told that the entire throttle body was bad, and that it would have to be replaced. The car is a 2011, less than 60k miles on it with regular oil changes and has never had any issues until this. The complete and immediate deceleration seems quite dangerous in my opinion. And having done some reading online, this seems to be a fairly common problem that Mazda is aware of yet has done nothing to rectify.

I purchased my 2007 Mazda Cx-7 from a dealership in greensburg, PA in February of 2014, it was purchased as a used car with only 36,500 miles on it. I had no problems with the car at first, then I noticed my gas mileage was getting worse, that is when on memorial day my check engine light would come on and then go off. I took it my mechanic because I was unable to get it in to the dealership for a week at some points and the light would have be off by then. Then when I was on my way home on the evening of 9/4/14 my car made a very weird sound any time I would try to push on the gas. I pulled the car off the road and there it sat until I could reach the service department on the following day. My husband took the car to the dealership and that's where it sat because he was informed that it was unsafe to drive? I went up after work only to have them tell me that they could not get the readings from the diagnostic test and that they would have to send it to an actual Mazda dealership, where it has been for almost a week. I was informed yesterday that my turbo and other un-mentioned parts had broken. I then waited to hear back as to whether the warranty that I paid an additional $2,000 for at the time of purchase would cover it, it will not cover this and they stated that the turbo was not considered a part of the "powertrain" so they quoted me a price of upwards of $3300 to repair the vehicle that I have had for 7 months. I have started to do research into this vehicle and I have found out that this is actually quite a common problem with this make and model and that the manufacturer will not stand by the product fully knowing that this is a problem and the consumer is left holding quite a hefty bill. I implore you to research this and force their hand so that "joe public" doesn't keep getting stuck holding a huge bill for something this company just doesn't want to fix.

After I have come to a stop the check ingine light and tcs/dsc indicator light illuminate. My car remains on but when I push on the gas throttle my car does not go anywhere. I have to turn off my car for a minute or so and then restart before I can drive. This had happen 4 times now (in a 2 month time frame). It usually happens when I am at a stop light and do not have a way to get off of the road. The check ingine light stays on for a day or so and then goes away. Then it will happen again. I have been driving on the road when this has happened and had to pull off quickly on the side of the road. This is very dangerous! I have an appointment with a Mazda dealership to have it looked at.

Loss of power when trying to accelerate. Puff of white smoke along with a clacking noise.

When driving with the a/c on, the ecm seems to malfunction and increase the speed of the car when the ac compressor turns on. If you are in the process of braking, the car will not stop and it will require the driver to press harder on the brakes. The car gets and extra boost of energy and even though you are braking, the car lunges forward and continues to roll further. If the driver is caught off guard, this will lead to an accident. I crashed my car into a family members house as I was parking. Luckily, the parking bumper slowed down the car enough so as to only slightly bump the house. It has happened in regular traffic as well. Luckily, I keep a safe distance from cars and brake early but now I brake even earlier just in case. Volkswagon had the same problem and they did a large recall on the vehicle because of the safety issue it involves. If you own a Cx-7 keep an eye out for this, especially when the a/c is on. It only happens when the timing is just right that you are braking and the compressor turns on a that precise moment so it will catch you off guard and scare the daylights out of you. I've been lucky so far but this could definitely cause major damage if not recalled in order to fix. Here is the info from a recall from Volkswagen. Volkswagen is recalling approximately 4,000 of its cars. The automaker will fix engine control module software that can trigger an unexpected increase in engine rpm, according to the national highway traffic safety administration. "these vehicles have an engine control module containing software that may not properly control engine idle with the air-conditioning turned on," NHTSA said in its summary of the problem. "in rare cases, the ecm may unexpectedly increase engine rpm. An engine surge caused by an unexpected increase in engine rpm may surprise the vehicle operator and can result in a crash without warning. ".

Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6) on October 25, 2009 my [xxx] and myself, [xxx] , were driving back from pennsylvania on route 15 in maryland in a 2007 Mazda Cx-7. As we were driving down the road we accelerated to pass another vehicle. As I accelerated the vehicle the gas pedal automatically went to the floor and would not slow down. I tried to take control of the violently speeding Mazda Cx-7. As I tapped the brake the car would not slow down, the car would just accelerate faster and shake back and fourth. At this point I had to awaken my fiance from sleeping to let her know we had a problem and to brace herself in case of accident. Knowing that the car was not slowing down by tapping the brake I used both feet to try to stop the Mazda. Finally after noticing the vehicle billowing gray smoke from the sides I knew I had to make a decision, or it could be life or death. I swerved into the emergency lane and stopped the vehicle off route 15. While still holding my fee on the brake as hard as I possibly could, the vehicle still tried to surge forward. In order to make the vehicle stop doing this out of control action, I was required to turn the ignition to the off position. While doing so I noticed the engine racing past 6000 rpms. I was in total fear for our lives. I wasn't sure if the car was going to blow up because of the now dark gray smoke that was coming out. We decided to not call the police. But instead we decided to take the chance and restart the vehicle, as we had no other means of transportation to get back to virginia. I am now to a point where I do not trust the vehicle. I have a true fear every time I think about me or my fiance driving it and any other Mazda on the road. I have never seen or heard of any such thing happening to anyone else. My fiance and I, along with the other 100s of people that were on the road this day could have been in grave danger because of the defect that has occurred with this vehicle.

As the proud owner of a new Mazda cx7, I felt confident after the first year of driving this SUV that it would carry me at least 10yrs. Until I begin to notice acceleration problems and noticing puffs of white smoke expelled from the exhaust pipe when it finally realized I was trying to increase speed. Took SUV to a Mazda dealer and was informed nothing was wrong with it. Fine, then began to hear like a rattling noise during acceleration (sounded like a rock in a tin can) sound then goes away after a few moments. Took to dealer again was told no problem. Well, on my way to work at 70 mph on busy interstate, I lose acceleration. Cost safely to the side of the road without being ran over by 18 wheeler,, had vehicle towed to Mazda dealer. I was then informed the timing chain broke, yes at 70,000 miles. Only then to be informed later that due to timing breaking my engine was ruined. I was then devastated, even more so after I was told it would 8000 for a new engine plus 2000 for labor. I had no other option but to park the vehicle and attempted to save money to have it fixed. Well that was 2 yrs ago and its still parked, and 2 yrs now without a vehicle. I had routine documented oil changes at Mazda dealers only, I took very good care of this truck. After searching the internet, I am reading the same incidents from thousands of people concerning the exact same issue. Mazda has finally states that there is a problem with the timing chains and has issued an extended warranty on it. But from reading reports, Mazda is giving people a hard time. Mazda cx7 are dangerous vehicles, someone could have been killed due to this poorly made SUV. I am reporting this because it really needs to be looked into before someone is killed to many people on the internet complaining about this failure. Please investigate this vehicle< we cant all be wrong!!!!!!!!!!!!!!!!!!!!!!!.

1. I was pressing on the gas pedal to accelerate as I was merging onto the highway via an on-ramp. The car was previously driving normally without any problems. 2. The car kept on accelerating after I removed my foot from the pedal. It continued accelerating even after pressing on the brakes (I could feel / smell the brakes working but the car would continue to accelerate even though no foot was on the gas pedal). The car continued to do this even after I put the car in the manual transmission mode. At this point I drove off to the side of the highway to stop the car and it only stopped after turning off the engine.
