general problems of the 2010 Mazda CX-7

My daughter was driving a 4 hour trip in florida on I-95 halfway into the trip she pulled into a parking lot to stop for lunch and before she could even turn off the vehicle, a fire erupted from under the hood. The car completely burned. There is a police report at jupiter FL police department # 22-184325.

I started getting noise from the engine for last 6 months. But when the rpm is greater than 2000. The noise decreases, when I took to the dealer service, they mentioned that timing chain need to be replaced. Mazda knows about the issue and admits it but never performs a recall.

Took car in for air bag recall (which was fixed). Dealer did a full circle inspection and found the timing chain needed replacement. We received a letter from Mazda January, 2012 stating they were extending the warranty to 7 yrs from the original warranty date or 70,000 miles whichever comes first for repairs to the timing chain. This letter leads me to believe they knew there were issues with the timing chain. Our car has 39,100 miles (obviously low for the age of the car). We were required to pay for the repair out of pocket because it was outside the warranty period. It seems very unfair that our car was not covered for an issue Mazda was clearly aware of in 2012. While it was not an actual recall, something was wrong with the timing chain and all owners should be compensated for failure of the chain. I do not know exactly what can happen to a car if the chain breaks, but my best guess is it will stop running, which is a huge concern regarding safety of the vehicle.

My daughter was driving the Cx-7 on the highway and it caught on fire. There was a pop and then smoke and flames. My daughter moved to the left shoulder as soon as she heard the pop and the vehicle engulfed in flames. The vehicle was a total loss. At the time of the incident the vehicle was in great condition. The vehicle was at 94,000 miles. An oil change was completed recently as well as all regular maintenance.

2010 Mazda purchased used at 70k miles April of 2015. I have had to replace the oil cooler, the entire vvt system and now a turbocharger has blown. 5k in repairs and the car is barely worth that.

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.

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. ".

2010 cx7 grand touring was purchased with 5,844 miles from dealer. We changed the oil & filter every 6,000 miles using recommended oil as shown in the owners manual (5w20). Manual recommendation is to change oil every 7,500 miles with normal driving conditions which is the case as my wife drove to and from work. At 37,000 miles, vehicle was started in 20deg f. Temps, warmed up for and experienced loud engine knock. Once driven, vehicle had no power and had troubles getting to hwy speed. Drove the vehicle to the dealer where we purchased it the next day and was informed the engine had excessive engine oil sludge under the oil filler cap. Service dept. Called me the next day and said they would need to pull the valve cover to investigate further to see if Mazda national would cover under warranty. We agreed since we properly maintained the vehicle and had nothing to hide. Two days later we received a call from the dealer and were informed there was excessive sludge and they would need to see receipts from where we changed our oil. We performed our own oil changes and did not keep receipts from the auto parts store where we purchased the oil. Dealer said without the receipts we would not get warranty work done and charged us $260 to do the investigation to better their case. I called national Mazda and all they did was read the notes from the dealer and were not willing to budge. The rep from Mazda ([xxx]) was extremely rude and could care less we were experiencing major issues with a car within the warranty. There are numerous claims similar to ours all over the internet. It appears Mazda has their standard "excessive engine sludge" pitch down as this is the common theme in all cx7 engine problems. We had the engine rebuilt at a local shop (paid $6,100) and now are told the turbo is shot as well which is estimated at another $2,000 to replace.

I was driving my Mazda when it started making this odd winding sound. At first it was not too loud but when I tried to speed up to get on the interstate, the sound got extremely loud. I brought it back home but barely made it up the hill to our street. I had the gas pedal to the floor but it had no power. I called road side assistance and they picked up my car promptly. When the dealership called me back, they reported that the engine had "gunk" in it. My husband changed the oil in the car but we never saved receipts for the oil, so we have no proof. I bought this car brand new in 2010. It only has a little over 32000 miles on it. The dealership is telling me that Mazda will not pay for the engine and it will cost $9000 to replace the engine. The car I drove prior to this was a Nissan altima and we also did all the maintenance to this car. I drove the altima for a little over 200,000 miles and it was still running well when I sold it. It makes no sense to me that this Mazda has a bad engine and it makes me even more mad that they are not going to replace the engine. ## VIN passed ## Mazda cx7 2010 ##.
