2011 Mazda CX-7 Problems

What owners report

Owners of this model year most often write about weak or fogged headlamps that need frequent bulb replacement, and about the front lower control arm ball joint recall (16V593000), with many complaints describing long waits for parts and intermittent rattles or creaking from the front end. A smaller but consistent group describes shuddering or harsh automatic transmission behavior, and several owners were concerned about the passenger-side air bag inflator recall and slow remedy availability.

   Exterior lighting

   Dim, fogged headlamps and repeated bulb burnouts

   • 32 complaints (21%)
   • median 49,646 mi at 4.0 yrs old (17 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2011–2026

   Owners describe headlamps that give little light on the road, often with moisture or fog visible inside the lens that cannot be cleaned off from outside. Many say low-beam bulbs fail every few months and that they end up driving with high beams to see. Some report the dealer called the fogging normal or could not find a cause, and a few mention the rear lamp housing looking affected as well. Scattered from a few thousand miles to well over 100,000 miles, with many reports in the 40,000-75,000 mile range and complaints about recurrence over several years.

   What to check: Inspect both headlamp lenses in daylight for internal fogging or a cloudy film, and check the service history for how often bulbs have been replaced. Ask whether any condensation or lighting service bulletin work was performed.

   “From the time I purchased this vehicle the headlights would retain moisture and fog up. This has supposedly been repaired by Mazda, but recurs and results with poor headlight illumination. The illumination provided by my headlights is reduced considerably due to this defect. I have 17,000 miles on this vehicle now and have repeatedly tried to have this problem corrected. I believe this defect to impose a danger.”

   NHTSA complaint #10712574, filed 2015-04, 8,000 miles

   “I bought this car november of 2013 I have had to replace both headlights once and the right headlight twice. The headlight covers either retain moisture or heat up to the point that it is burning the lights out or melting the cover. The covers are so fogged up that I have to have the lights on bright all the time to have enough light to see. There is an obvious defect most people don't have to replace headlight every 4 to 6 months.”

   Suspension

   Front lower control arm ball joint wear (recall 16V593000)

   • 47 complaints (31%)
   • median 70,000 mi at 6.7 yrs old (13 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2016–2026

   Complaints describe creaking, clunking or rattling noises from the front end, sometimes while driving at speed, that owners link to the lower control arm ball joint. Many say they received the 2016 recall notice but were told parts were unavailable, in some cases for well over a year, and a few describe the joint separating and loss of steering control. Some also mention tight or off-center steering felt along with the noise. Mostly reported between about 10,000 and 90,000 miles, with many owners noting the notice arrived years before any repair was possible.

   “I received a recall notice for ball joints however no parts were available at the time to correct the problem. Waited over a year and the ball joint let go so I was unable to drive my Mazda. I took it to the repair shop and had it fixed. 3 months later I received a notice from Mazda that the parts were in. I called Mazda 3 times asking for a reimbursement as I had to pay out of my own pocket for a recall that they were unable to fix. I have not received any calls back. …”

   Air bags

   Passenger air bag inflator recall and slow remedy

   • 38 complaints (25%)
   • median 80,000 mi at 5.9 yrs old (6 state mileage, few)
   • 2 mention a crash, fire or injury
   • filed 2015–2025

   Owners describe receiving notices about the passenger frontal air bag inflator and being told to keep passengers out of the front seat until parts arrived. Complaints say the wait stretched for months and that dealers had no remedy available, and some owners ask why only the passenger side was covered. A few describe air bags not deploying in a collision. Reports cluster from 2016 onward across a wide mileage range, from under 10,000 to over 200,000 miles, as owners responded to recall mailings.

   “Takata recall issued may 25, 2016 and we were just notified august 12, 2016. Remedy not yet available and Mazda suggest the vehicle should not be driven. We have not had an accident yet, but if we do, how can we not drive a car that we own?we have to work to pay bills. How many months, and/or deaths, until a remedy is available?”

   NHTSA complaint #10895309, filed 2016-08, 24,000 miles

   “Takata recall I received a letter in july, 2016 informing me of the recall and asking me to wait until further notice from Mazda. They suggested I not have anyone ride in the passenger seat until repaired. I called Mazda dealer 10-18-16 and still do not have parts. That suggestion is not tenable and what about the danger to the driver? I feel this is an unreasonable amount of time to wait for this recall to be taken care of and repaired. Thank you.”

   Transmission and drivetrain

   Harsh or delayed automatic transmission shifting

   • 11 complaints (7%)
   • median 62,500 mi at 5.0 yrs old (8 state mileage, few)
   • 2 mention a crash, fire or injury
   • filed 2011–2022

   Owners describe the transmission bogging down between shifts, revving and then engaging hard, or refusing to go into reverse. Complaints say dealers or shops diagnosed a failed transmission and quoted replacement, often shortly after normal maintenance. A related group describes the vehicle losing power or failing to accelerate while driving, sometimes traced to the throttle body. Mainly reported between about 60,000 and 75,000 miles, with a few power-loss complaints near 60,000 miles.

   What to check: Test drive from cold through all gears including reverse, and ask whether the correct Mazda-specified automatic transmission fluid was used at service intervals.

   “On 12/14/2015, I was driving about 60-65 MPH on a maryland highway at around 10am. I was in the next lane beside the fast lane. The 2011 Mazda cx7 started to decelerate. I looked down at the gages to make sure I didn't inadvertently go into neutral. I was still in drive. I hit the brake, not coming to a complete stop, and then stepped back on the gas, pushing the gas pedal to the floor and the car would not accelerate. It went down to about 20 MPH. …”

   NHTSA complaint #10810217, filed 2015-12, 61,000 miles

   “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. …”

Buying note. Check the headlamp lenses and bulb replacement history carefully, and verify that recall 16V593000 and the air bag inflator recalls were completed on the specific vehicle. A pre-purchase inspection of the front suspension and a thorough transmission test drive are worthwhile on this model year.
