The driver's seat power adjust has been squealing extremely loudly each time I adjust it, and based on what I've read, this is a known problem and could be a sign of the driveshaft/motor failing.

I would like to express that this is now the second time I have had to take my car in for service and repairs due to the soy-based components they use in the electrical harness that have been continuously eaten thru by squirrels. My car's horn and headlights no longer work again and this is now the second time. I ask that these elements are recalled immediately for safety reasons. Wire harnesses are a critical component to vehicle safety. Wires that can degrade during the normal service life of a vehicle can be deadly. Think about a wire harness with insulation that's been eaten that controls the ABS, fuel injection or an airflow sensor, and you hit a bump in the road and it shorts. Now you lose power or braking. Are we willing to have someone's vehicle fail and the people seriously hurt or dead because of a fundamental design flaw? I can email pictures from my phone to provide evidence of the damage. Again these wires should never be soy based. I don't feel like dying anytime soon because a rodent chewed through a critical component.

The led daytime running lights on both sides of my 2016 Mazda Cx-5 have burned out/stopped lighting after 39K miles and out of the warranty period. The repair requires the replacement of the entire headlight assembly with an estimated cost of $1200 per assembly. ($2400 total). Because this is a safety issue, and one apparently known to Mazda, this should be a recall.

I recently purchased a 2016 Mazda Cx-5 from a non-Mazda dealer, however after paying $21,000 for the vehicle I realized the daytime running light was not working! my biggest surprise was when I went back to the dealer to have them repair it and found out the entire headlamp would need replacing to the tune of $1,100 dollars! today I called Mazda and they told me there is nothing they can do about this because the car is out of warranty! it is especially distressing in that so many other complaints are all over the internet about the same problem when the cars are still under 30,000 miles! I hope someone can do something, Mazda should help customers in this way, since this is obviously a defective part!

Electric parking break (epb) warning light start blinking after the release of the brake. I lived in a warm tropical weather. In my understanding this function works on cold weather.problem persists intermittently. If vehicle turned off, problem "disappears" but appears again when the break button was released. Weeks later the car started to activate the smart city break alarm when moving in my neighborhood and in a city street with no reason, suddenly, and bringing a safety issue. Also started to make strange noises related to the brake, similar when the brakes or pads get wet and making the car forced to be moved when pushing the accelerator pedal, making the vehicle difficult to move, no matter break is released and turning it slow and vague. An electronic diagnostic report was made and shows the following codes : code C2005 (electric park brake motor gear unit (rh) circuit malfunction code C112A (incorrect electric parking brake motor gear unit position) code C2006 (electric parking brake motor gear unit (LH) circuit malfunction.

Vehicle's infotainment/navigation system froze up. When in operation the screen just blinks on and off. Upon bringing vehicle into dealership we were told that the item is backordered as there are so many problems with the systems they have no time frame to get this problem fixed. Upon research on line it also appears many others are sharing their same challenges with systems that do not work.

I had the car started and turned the headlights on and the car stopped. Did several times shutting off and turning off. All of the lights on the panel flickers. After several times every thing back to normal. After about 2 months it happened again. I tried it several times again and I even decided to try and drive and turn the lights on while driving and the car stopped. Went home stopped at my mailbox to get the mail. Turned car off, back on, lights a flashing, engine light came on and stayed on, drove into my driveway. Turned car off and back on a few more times. Finally was working ok. And it has been a couple of weeks since. Afraid to be driving the car at night though.

Started car in driveway 2/10/19, 4 pm 'engine sounded like timing was obviously abnormal. Random automatic braking noted when car in motion, within one block of leaving driveway. Immediate inability to accelerate beyond 10-12 mph experienced. Error messages then observed on car dashboard warning sectors: Check engine; traction control: Tire pressure monitoring; smart city brake support malfunction-forward scbs disabled. Car unsafe to drive to dealer 12 miles away. Car towed to dealer site 2/11/19 Monday am. Car has 28,330 miles per odometer; service maintenance up to date, as manufacturer recommended. Dealer assessment of cause on 2/11/19 reported as 'rats nesting in engine and eating through soy insultation on wiring on engine harness.' Repair costs of > $1,500 estimated. It seems that insulating engine component with nutrients attractive to nesting, ubiquitous vermin is a serious safety concern for car owners and users. Any NHTSA guidance on this critical issue?

Ebrake would not disengage on the Mazda Cx-5 2016 GT with city brake and electronic E-brake at 36,100 miles during various parking locations scenarios. Vehicle would start normally at push of start button but the E-brake light would stay on in the flashing mode. Turn engine off/restarting would resolve the problem temporarily just to return to the same issue at random parking locations. Dealership suggested a replacement battery main 12 volt battery for $185+tax+installation. Battery replacement suggested based on a claim of low voltage measured at the E-brake switch located on the center console. There was no other solutions provided by the dealership for further testing/isolation of issue priir making a payment, to include confirmation that in fact the battery is the culprit. Utilizing an alternate/test battery could be a temporary testing solution. Payments were made as requested and the issue of the flashing E-brake light flashing/E-brake not disengaging is less apparent with 2 incidents 1 month after battery replacement. Incidents observed while in covered/uncovered parking scenarios, outside temperature oscillate from 75 to 92 F. vehicle rear brakes were replaced under 5000 miles by dealership due to noises and premature wear. Vehicle also has a Mazda remote start system installed by dealership with a history of electrical failure of the A/C compressor. Documentation available for review.

Led daytime running light on passenger-side headlight flickers and is very dim. On a few occasions, the driver of vehicle in front stated that it looked as if my headlight was out as well. Vehicle is only 3-years old. Mileage should not affect electiral led components. Drl's or headlights are required during adverse weather conditions or when operating the windshield wipers.

While on a recent highway road trip, my 2016 Mazda Cx-5's driver side daytime running led lights, which come equipped with the technology package, stopped illuminating properly. The daytime running lamp led lights in question will flicker or not illuminate at all. I found this to be a safety issue as daytime running lights are equipped on vehicles to enhance visibility and safety. A flickering daytime running lamp can cause serious safety concerns resulting in distracted driving related collisions. Mazda advertised these specific headlamps as being a long lasting and providing enhanced safety as they adapt to changing roadway conditions. Upon conducting independent research into the drl (daytime running lamp), it was learned that many other owners of the 2016 Mazda Cx-5, with the technology package / led headlamps, have been experiencing this issue almost as soon as the basic factory warranty expires. It was then learned the average cost to get this situation remedied would result in having to pay almost $1500 - $2000 to get the whole headlamp unit replaced. Research on the NHTSA website revealed a faulty gasket at the base of the headlamp unit which caused moisture/gas to develop on the interior of the headlamp lens, this is also present on this vehicle. I feel this could potentially be causing the headlamp drl to malfunction due to a moisture build up, or the unit is all together defective for a certain grouping of Cx-5's with this headlamp assembly I feel a recall investigation should be conducted to determine the source of the malfunction. I feel this is a significant issue as it was learned there was a recent national back order for these headlamps, I find that suspicious if they were to be in proper working order.
