2014 Mazda MAZDA6 engine problems

Filed Jan 4, 2024 · Engine · TX

The incident occurred while operating a diligently maintained 2014 Mazda 6 Touring, overseen by dealership service. While driving, the check engine light illuminated, prompting an immediate halt. Upon inspection, a concerning observation was made: the coolant level was significantly low. Despite no apparent leaks, further examination revealed a crack in the cylinder head, allowing coolant to mix with the oil. This issue, specific to Mazda's 2.5L Skyactiv engine, has been identified as a manufacturing defect, independent of overheating. Notably, this problem has been echoed by multiple users, confirming the presence of defective cylinder heads in these vehicles. This flaw necessitates an expensive repair, absolving the vehicle owner of any responsibility. Despite the widespread occurrence of this issue, Mazda has declined to issue a recall for vehicles equipped with these faulty cylinder blocks. Online forums and discussions have highlighted numerous instances of identical cracks in the same location, affirming the prevalence of this problem with Mazda's 2.5L engines. This poses a serious concern for vehicle safety and warrants attention from both Mazda and vehicle owners. Additional information regarding this issue can be found through the provided links.

Tl* the contact owns a 2014 mazda 6.

For seemingly no reason, the vehicle will restart and stall while driving and multiple warning lights will illuminate. This has happened while driving slow, fast and while turning. When this happens, I need to immediately pull over and restart the engine. The check engine light turns on and indicates an abrupt voltage change issue, but soon turns off after a few power cycles. This started to happen more and more often, and more recently, I had the car not able to start as if the battery died. All my electrical components, such as headlights and hazard lights shut off and after about 10 seconds, they all turned back on and running normally. At this point my vehicle started up again just fine. This has nearly caused an accident a couple times and no mechanic has been able to diagnose the issue yet. Although, this issue seems alarmingly close to a recent recall that was announced for 2018-2019 mazdas relating to a software issue that causes unexpected engine stalling relating to the fuel-saving cylinder deactivation technology. Unfortunately, even though my vehicle contains the same technology, it wasn't included on this recall list.

With no consistancey, the car would loose power. At times, I thought the car would loose full power, in the middle of my commute, I would be forced to pull over and shut the car off. Most times, the car would return to normal conditions. When I brought it in for repair, byers mazda of columbus, told me it needed a tune-up. Once again, the car almost stalled out and I managed to coast into a parking space. Now the same dealership is informing me for the first time that the car has an I-loop system and the battery that should have lasted five years, now less than the 3 years old, needs to be replaced for over $500.00. I bought this car used with an extended warranty and although it was my mistake, the dealership never disclosed the I-loop system and the problems that go with it. This I-loop battery will apparently last 2-3 years only and is very expensive. I guess it is legal for dealership sales reps to misrepresent the car maintenance because they say it is my responsibility to know what I purchased. I will never buy from byers auto for any model car!
