2010 Mazda CX-7 Problems

What owners report

Owners of the 2010 Mazda CX-7 most often describe front suspension noise and ball joint concerns, many tied to a 2016 front lower control arm recall that owners say took a long time to get parts for. A second large group involves the passenger frontal air bag inflator recall and air bag warning lights. Engine complaints center on turbocharger and timing chain trouble, and several owners describe headlights that fail or grow dim.

   Front lower ball joint / control arm corrosion and noise

   • 59 complaints (38%)
   • median 68,000 mi at 7.0 yrs old (15 state mileage)
   • filed 2013–2019

   Owners describe popping, rattling or drumming noises from the front end at low speed and around turns, and some report the wheel separating from the vehicle. Several complaints state that the vehicle was covered by a front lower control arm recall but that dealers told them no repair would be made until an actual failure occurred, or that parts were unavailable. In some cases the vehicle was towed and the control arms, ball joints, rotors or axle were replaced. Reported from roughly 40,000 to over 110,000 miles, with many complaints filed in 2016-2017 while the ball joint recall parts were scarce.

   Recall 16V593000

   What to check: Ask whether the front lower control arm recall (16V593000) was completed and get the paperwork; have a shop inspect the front ball joints and control arms for corrosion, looseness or popping before buying.

   “Nhtsa recall number 16v-593. My car makes a rattle when I step on the brakes. When it is wet outside my brakes make a different noise until they dry out. Mazda said it wasn't a problem. Another business I go to said it's probably the rocker arms that need replacement.”

   NHTSA complaint #11066157, filed 2018-01, 40,000 miles

   “Mazda is refusing to fix the recall on my vehicle saying that it's not a safety recall. The last time I checked the lower control arms separating from the ball joints was a safety issue. I have called the dealer and they can't get the part or don't want to they told me the first time it was the brakes popping and now they say nothing is wrong with it at all. Mazda corporate doesn't seem like they care either. They told me it was safe to drive not to worry about it. …”

   Turbocharger failure with smoke and oil loss

   • 19 complaints (12%)
   • median 55,000 mi at 4.9 yrs old (18 state mileage)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $6,100 (median of 5 quotes)
   • filed 2010–2020

   Complaints describe a whining or howling noise, loss of power, and heavy white or black smoke from the exhaust, often traced to a failed turbocharger. Several owners report oil being consumed or lost to the point of engine damage, with one complaint describing the cabin filling with smoke. Dealers reportedly replaced the turbo in some cases and in others pointed to oil sludge or declined warranty coverage. Reported from around 18,000 to 85,000 miles, sometimes within the first few thousand miles of ownership.

   What to check: Check the oil level and condition and ask for turbo or engine repair records; look for smoke on a cold start and listen for whine or whistle under acceleration. A service bulletin describes a procedure for evaluating oil consumption.

   “Takata recall. My complaint is why there has not been a recall on the turbo charger for my vehicle. I was driving my car and the entire cabin filled with smoke that I had to pull off the road. I had to roll down all the windows because the it was so bad and thought the engine was on fire. This is not safe to have this happen. I've googled this and there are many complaints on replacement happening twice. …”

   NHTSA complaint #10853863, filed 2016-04, 65,000 miles

   “The turbo made a loud whining noise when the accelerator was pushed and you could not accelerate. Alot of white smoke was flowing from the exhaust. We immediately pulled over on our way home from out of town and called aaa to tow the car back to the service dealer in parkersburg wv. The vehicle only has approx. 19,000 miles on it with service records showing proper oil changes. The vehicle is under warranty and Mazda sounds like they don't want to cover this problem.”

   Engine

   Timing chain noise and engine rattle

   • 16 complaints (10%)
   • median 40,036 mi at 5.3 yrs old (14 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2011–2020

   Owners describe a rattling or knocking noise from the engine, sometimes loudest at start-up or below about 2,000 rpm, and dealers diagnosing a stretched or worn timing chain that needed replacement. Some complaints say the repair was recommended during unrelated dealer visits, and one owner notes Mazda had extended warranty coverage for the timing chain to 7 years or 70,000 miles. Several report paying out of pocket. Reported from very low mileage up to about 110,000 miles, often after cold starts.

   What to check: Listen for a rattle at cold start and ask whether the timing chain has been replaced or covered under the extended warranty; get any chain work documented.

   “I purchase the Mazda cx7 on march 20 2010. Within 3 weeks I notice a rattling noise from the engine when start up the car. I took it to 2 different local Mazda dealers over 8 times since purchase and they replaced 3 motor mount but the problem still exist. This year I took it to the dealer twice and they refused to fix it. They wouldn't even schedule an appointment to look at my car. My car is still under warranty. …”

   NHTSA complaint #10502033, filed 2013-03, 1,000 miles

   “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.”

   Exterior lighting

   Headlights failing or growing dim

   • 16 complaints (10%)
   • median 83,490 mi at 7.2 yrs old (9 state mileage, few)
   • filed 2014–2024

   Complaints describe low beams that stop working suddenly or bulbs that burn out repeatedly, in one case about every six months. Some owners report fogged or melted headlight housings and say the lamps are too dim to drive at night, leading them to use high beams. Dealers reportedly told owners the failures are common, and one complaint mentions the control module as a suspected cause. Reported from around 20,000 to over 175,000 miles, with several complaints filed after several years of ownership.

   What to check: Operate both low and high beams and inspect the lenses for fogging, moisture or melting; ask whether headlight assemblies or bulbs were replaced recently.

   2 excerpts from owner complaints in NHTSA records

   “Headlight bulbs have burned out every 6 months since we bought the vehicle in 2010. Over the past few years, the lenses have fogged up to the point headlights are worthless. Took the vehicle to the dealer, one seal is bad and the other side has melted, cost of repair is nearly $2,000. This is a safety issue and looks to be a common defect in this make/model of car. We now drive the car only during daylight. If we need to at night, we use high beams exclusively as we can't see a thing with regular headlights.”

   NHTSA complaint #11082328, filed 2018-03, 112,000 miles

   “The headlights (low beam) on my car simply stopped working all of a sudden. Checked the fuses and all are fine. High beams and signal lights work fine, it's just the headlights. Have seen this same description in other websites as possibly the control module had a short circuit and this is a very common thing to happen to these cars. Mazda is not accepting this as an in warranty repair even though this is a major common complaint. My car is out of warranty already, so I'll need to pay this repair out of pocket.”

   NHTSA complaint #10934557, filed 2016-12, 177,473 miles

Buying note. On this model year, confirm in writing that both the front lower control arm recall and the passenger air bag inflator recall have been completed, since owners report long waits for parts. A pre-purchase inspection focused on the front suspension and turbocharger, plus a cold-start listen for engine rattle, is worthwhile given the sample of complaints.

Summary written with AI from a sample of 60 NHTSA complaints for this model year (picked at random, with complaints that state a mileage and recent ones taken first), then checked automatically against the source records. Where a problem shows a complaint count, every complaint for this model year was matched with fixed keyword rules (written with AI and tested against the sample), and the mileage, age and repair figures are calculated from those complaints; owners' figures are as stated, not verified.
