My car has been showing a pop-up message that states that my engine needs maintenance. The message appears every 3 to 5 minutes. I have checked it three times with three different auto shops and they cannot find what is the problem to it. We have tried to clear the message, but it keeps coming back. it is not the oil change because it is a different message and I get those on time always. Please someone help.

Check engine with P0741
The oil change has already been done but how can I repair it?

While i was driving i hit a small bump and i saw that the thermometer guage dropped and my oil light came on {i just did a oil change two weeks prior} and then the car doenst crank at all. The battery is good , the starter is bad so i bought a new one. I just dont know what caused the electrical issue. The right side of the interior fuse box are burnt starts at number 15 and goes on so it had to be all connected right ? how can i figure out which wire tho ?

I had an oil change on it done 3 weeks back, the week after driving it I had to top it up with some oil, a lot of smoke comes out the exhaust pipe and the color is a light blue, the smell of chemicals and smoke come through the air vents when driving, car is not able to make a long distance drive. Not even close to a 6 hour drive it would break down

My vehicle has 165,000. Lately car cranks over longer than usual and when it finally turns on it will miss fire for a few seconds and then be ok. Random times check engine light registers a P1604 code. Now I have replaced fuel pump, ignition coils, spark plugs, fuel injector, cleaned intake manifold, replaced PCV valve, oil change, cleaned all grounds and terminals for battery and installed a new battery with 650 cca which the factory only called for a 500 cca. This only happens when car sits for over 4 hours like over night or after working 8 hours. Compression is at 150-155 depending on if doing it with car completely cold lower compression reading and after a 10-15 minute warm up the higher reading. I am wondering if maybe issue with the PCM? Any help would be greatly appreciated.

The light is on saying parking break malfunction. Visit dealer I went in for an oil change they said the only thing they could see was that the light was on.

My car was service to change Oil pump and crankshaft, from there my car do not want to start at all, it only turn the engine.

Crank, no start. No spark, no fuel activity. 1st code p171. Replaced MAF, both O2 sensors, pcv, iridium spark plugs twice, oil change and both oil/air filters.
