Tcs and check engine light is on. The car does not have power even if the gas pedal is pressed all the way, the car moves only up to 5 miles per hour (RPM power). Vehicle loses throttle. Ac blows warm when tcs light is on. There is a white smoke from the exhaust. This usually happens after the car is parked for couple hours. The same issue occurs several times within a period of year and a half. My car was @ service shop more than 2 months. I contacted mazda corporate office in several occasions and they are aware of the issues I have with the car, but they did not respond positively.

Was driving and all of a sudden lost power and a howling noise no check engine light came on. Pulled over to see what it was and nothing visible no leaks nothing. Had my wife hit the has and no noise. Stared driving and noise came back and white smoke. Just had an oil change done and next oil change due in about 1000 miles. Drove about 20 MPH to get home check oil and it was ok. The white smoke makes me think the turbo went on my car. I just purchased this car in october of 2015. It's been back to the shop for electric problems with the key and radio that still not resolved. Radio shuts off and beeps that key is not in car.

After I have come to a stop the check engine 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 engine 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.

On 8/31/14 I noticed a rattling noise when I accelerated as well as a whining noise. The noise was intermittent and did not occur all the time, but was a distinct noise coming from underneath the vehicle. I had not had any check engine lights illuminated or any other warning lights. I brought my vehicle into my local mazda dealership and they advised it was the turbo and in order access appropriately they would need to tear down the engine. After reading online there are numerous documented issues with turbos, vvt timing chains and engine issues with mazda cx7. The shop called me back 2 days after I dropped it off and said I would need to replace the turbo & I need a new engine. They also stated since there was oil sludge present that I would be responsible for $9000 costs. I provided the dealership my oil change receipts including the last oil change that was done in june. My car was still within 3000 miles and was not due a oil change, however the owners manual stipulates recommended changes every 7000 miles!! The dealership advised that when I brought it in no oil was in the dipstick and because there was sludge mazda is denying my powertrain warranty (which is still active) due to not maintaining the vehicle. This is absurd, I have maintained my vehicle and mazda is using this as an excuse to not be responsible for a obvious defect in their vehicle!!! There are many documented instances about this same scenario happening with others all over the internet, this issue is a result of a defective turbo and not due to lack of maintenance. Mazda extended turbos and vvt timing chain issues to 7 years because of this same scenario for 2007-2010 mazda cx7s but when I asked about ssp 86 im being told my vehicle does not qualify. I would like to know why mazda can get away with not abiding to their warranty and request this be investigated. Thank you

I was starting the car in the morning on my driveway. I switched the car on r and I start to back up. When I pressed the brake pedal , I realized I have no brake power. It was impossible to stop the car. I had to used the parking brake to stop it. I've tried for 5 minutes to see if brakes are working with no result. They were dead!! When the card was started , there was no malfunction indicator on the dash.2 months before this, I went to the dealership reporting that braking performance decreased a lot. They investigated the car and found "no defect" and told me the car is working as it should...yeas sure!! My luck was that I was not driving the car on the roads. Imagine loosing brake ar 60 MPH.
