What owners say
One day after oil and filter change, engine LOW OIL LEVEL light illuminated on dash. Engine oil dipstick displays full oil level; no signs on oil leaks under the vehicle. Appears to be failed oil level sensor. Upon restarting the vehicle, LOW OIL LEVEL light is turned off. Intermittently returns after some time of driving. Have not observed light turning itself off without shutting down the vehicle.
Received a "LOW ENGINE OIL LEVEL” warning message before the regular oil change interval of 7,500. Light came on 11/20/24 after purchasing the vehicle from a Mazda dealership 8/10/24 (~3 months). Model and VIN were impacted by the Mazda Valve Stem Seal Settlement. This issue was not disclosed by the dealer.
Low Engine Oil Light keeps appearing at seemingly random intervals. I will heat up my vehicle, begin driving, and sometimes after 10 minutes, sometimes after 20 minutes it will come on. I drove 2.5 hours and it did not come on at all. It first started Friday 11/29 and was driven to and from a few places and came on 50% of the time. The 2.5 hour drive occurred on Saturday 11/30 and the light did not come on at all.
Low oil level message on cluster 1000 mile away from my oil change mileage indicated by the dealer.
Low engine oil light is on again, I had one at 4600 miles and keep happening every 5-6000 miles. I had 7!! oil changes on a car that is 2.5 years old and it is at 29000 miles. I am sitting at the dealership and they are telling me nothing is wrong and despite of the valve stem cap replacement available they are not willing to replace it. In addition I had my battery die and needed to be replaced at 23 months after purchasing a brand new car - due to a faulty system. This is getting extremely upsetting. And dealearships do not care.
It has an oil consumption issue. Every 3,000-3,500 miles is will give the oil low light. It will be 1 quart low. The car takes 6 quarts of 5w30 synthetic oil and requires oil changes every 7,500-8,000 miles. I have had to put a quart in every time. I have taken it into the dealership and a third party oil service as well. The dealership has no idea why it keeps running through the oil. They state that it's a known issue but no recall.
On multiple occasions, low oil warning lamp illuminates and I have confirmed low oil level. Dealer is unable to confirm and refuses to address Mazda TSB because oil level is no longer low since I topped it up. The failure lies in the valve seal assembly. My safety and that of my passengers is affected because in the event of a low oil incident, my ability to safely drive the speed limit and/or accelerate quickly is compromised. Should a catastrophic failure occur, engine would lose all power. Date of most recent incident marked below.
Low engine oil level since I bought it in September 2021. I’ve had it at the dealer three times and they’ve said there are no codes on the car but they are on my Mazda app. They want me to drive it over a hour away with low oil to prove to them that the engine oil is low. I did this, shut the car off, the light went off and when the engine oil level was checked it read one quart low.
“Low engine oil level” light comes on periodically for last several hundred miles. Dipstick show oil level to be appropriate.
