Mazda CX-7 knocking problems

Filed Oct 6, 2017 · Airbags, Electrical · FL

Took car to mazda for airbag recall, replaced airbag but mazda tells me the actual sensor that tells the airbag to deploy does not work and its my responsibility to fix it. Prior to the recall the sensor did not come up on the dash after the recall I now have a light on my dash and mazda is telling me its 700.00 to replace fix and part and labor. Electrical car shorts out all the time, windows, engine, lights work one day not the next when doors open. Car stalls out when driving and system reboots. Other issue is I have spent 7 thousand dollars in repairs on this car. I have black smoke coming out of the tail pipes, ive replaced thousands of dollars in parts. Engine light wont go off. I took it finally to auto zone for a free engine diagnosis to get a print out and now the emissions valves are showing faulty. Its burning 2 quarts of oil about every couple of weeks/monthly basis. Ive replaced motor mounts, coolant/oil parts, air compressor, headlights, bumber, wiper blades, electrical control panels, rocker arms, spoilers that have cracked with weather, the car still needs another motor mount, I now have a knock in the engine like its the lifters and I still have another year on this 5 year loan on this car. I have to keep rolling payments to the back of the loan to keep up with the repairs. Its very frustrating. Ive never had this many problems with any car I have purchased ever!!! Even the parts department at mazda has said what do you expect you purchased a plastic car on wheels. Is there any other people experiencing problems besides myself?

* engine issues when the A/C compressor locked up. This is a known issue in this make and model. This happened around 36k miles while I was driving on a freeway. We had to coast into the next exit. * engine knocking issues. They still persist and started around 50k miles. * engine resistance. Alongside the knocking there seems to be a good amount of resistance when taking your foot off of the pedal for acceleration. * they added a factory extension to the radio for the ipod. Ever since they installed this, the rest of the electrical components have been overloaded. - headlights go out frequently. This concerns me as my wife drives the car and I wouldn't want both to go out at the same time. - the battery won't hold a charge if not driven for a few days. The dealership acknowledged that the radio has a 'parasitic draw' on the battery causing these issues, but refuses to take responsibility for their installation. Their solution is to charge $800+ for a new head unit, which is outrageous since I never did anything to the factory head unit.

Prior to this date, which lead up to the last incident, upon getting the first few oil changes, at a dealership where I purchased the car, the engine began to sound like a truck (oil used was not synthetic and I were scheduled to come back in 5-months). When I inquired about it, I was told, "that was the way it was supposed to sound". After that comment, I changed to another dealership for service. The knocking continued, to this day, still. Over the years, the system lights would come on periodically (passenger air bag, check engine light and tire sensor) and the cooling fans would run after you turned the car off. Most times, they would reset themselves. Moving along, recently on 07/15/14, I was returning home for the evening and the car shut down on me. The steering control was hard but I kept it from crashing the wall on lincoln dr. As I flagged the traffic to proceed, I was able to start the car only to advance to the end of the drive. Before I reached home, the car shut down 5-times. Finally reaching home it sat until I were able to get it to another dealer, closer to home. How about, the engine is shot, the radiator had a leek, I knew nothing about and the dealer says, "it will not start, now". I drove it to the dealer. Oil light was on and smelling as if I burned something, while it knocked. Check engine light and passenger air bag light were on when it cut-off, as I pulled into their driveway. I restarted the car found a parking space. Once the ignition shutdown, the cooling fans came on. Dilemma, I leased the car new in 2007. I bought it, with present car payments until 2016, in 2010. The dealer requests the engine and radiator to be replaced. There is no warranty, especially after 100,000 miles and I have scrap on my hands. Where does one go from here as mazda used to be reputable? The engine shouldn't have any problems before 200,000 miles.

Car started to make a ticking noise from the right side of the engine compartment. Took it to a mechanic and was diagnosed as a timing chain related issue. Will cost about $1500 in parts and labor to replace timing chain, vvt valve, and sprockets.

As I was driving my mazda ( with a turbo engine) along the highway it began to decelerate on its own and making a loud knocking/grinding noise. It stopped on the road going up a hill with no turnouts. So it appears that the turbo blew up. It will start, but I cannot go anywhere. I have also had to replace gaskets on my oil filter housing unit, as the stock gaskets were faulty and causing a severe oil leak. Also, my emissions regulation ( egr) valve is bad and therefore will not pass smog. Each of these issues I am seeing more and more complaints about from other owners of the same vehicle. Mazda has made a horribly defective car and refuses to do anything about it except to claim owner negligence. I bought my car with 40k miles on it and it has been falling apart from the start. There is absolutely no excuse and this is not owner negligence, it is mazda negligence and refusal to make anything right on their completely defective vehicles.

There was a knocking almost as if the car was a diesel, brought the car to milford mazda in milford ct after purchasing the vehicle a month earlier at bobs in milford ct. The mazda dealer replaced the vvt december 2012 the service engine light goes on and I take it to the local garage and they get a code for camshaft, I bring the car to mazda who tells me upon arrival with out even looking at the vehicle that I need a new engine and it wouldn't be covered under my extended warranty because they are sure there is sludge in the engine, yea same story everyone else gets. I faithfully had my oil changed every 5,0000 miles max as this was drilled in my head growing up from my dad. Approximately some time in march I was driving to work I get this loud whining sound coming from the engine and the car loses all power the turbo went. I have a new turbo installed and still supposedly need another vvt just 2 years after they replaced this part and now there is a humming/whining noise coming from the rear of the car not to mention (2) tie rods are bad. This car is no doubt a piece of crap that I still owe 13k on and mazda corporate will not even return my call. There has to be something that can be done with all the same complaints.

While driving on the highway I heard a ticking noise after a few seconds later the car lost power and smoke came out of the exhaust. When I pulled over I took the cover off from the engine and noticed that there was oil coming out from where the top of the oil goes.the oil pressure on the block was compromised due to failure of the turbo. When taken to the roger beasley mazda dealership and the car was cranked the dip stick shot out from the engine. The dealership indicated that there was carbon build up but could not explain why. The car was towed to another acs certified mechanic and confirmed that the engine failure was due to the failure of the turbo. Before taking the trip on 4-18-2013 I took my car the mazda of mesquite dealership because I heard a ticking noise and the technician indicated that the noise was normal. Also the technician performed msp 36 reflashed PCM with updated software and cleared all fault codes since there was a recall. Three weeks later the engine goes out. The manufacture warranty expired, but have a in service warranty. The in service warranty agency denied the claim indicating that it was not normal wear and tear of the engine failure. I contacted the dealership and also emailed the manufacture to express my concern and both agencies directed me back to the in service warranty. Both the dealership and in service warranty are not willing to assist in the cost being that the cx7 model is a lemon in my opinion. There have been many claims against this model by other consumers in which was confirmed by the employees at the georgetown roger beasley mazda dealership. The employees indicated that the cx7 model has a lot of problems that is why the cx5 replaced the cx7 model. Since the claim was denied I have spent over 1000 which does not include any repairs, on a side note I was 300 miles away from home.
