Car does not get to normal engine temperature

ANSWER : Some model Hondas have the engine ECU in the location you described. Now that doesn’t mean you need an ECU, ECU failures are actually pretty rare. But it could be a clue.
Many electrical component failures occur at a certain temperature. A weak solder joint may expand and a circuit board lose the connection when the temperature rises. This kind of thing happens most often in fuel pump relays and power relays. Those would be the things that I would take a hard look at in your case. If you contact Your Mechanic they can send a technician to your home or office to check out your stalling Honda and let you know just what it will take to solve your problem.

ANSWER : It sounds like the cooling system is not performing as it should be. This could be due to a low fluid level, a restriction in the system, or a faulty temperature sensor. I would recommend having the coolant level checked first to make sure that it is full as this would be the most obvious sign of an overheating issue. I would then recommend having the temperature sensor inspected and tested by a qualified mechanic. Once this has been done, if the issue is not found yet, I would recommend having a coolant flush performed to remove any restrictions that may be in the cooling system.

ANSWER : Hi there. Check the battery and alternator to the vehicle. With all of the electrical issues that you are having, it sounds as if the battery is not charged and making the engine stall out due to lack power. Check the battery for a 12.6 volt reference and load test the battery. If the battery fails, then replace the battery. If the battery passes, then check the alternator and see if its putting out the full amount of amps. If you need further assistance with electrical issues, then seek out a professional, such as one from Your Mechanic, to help you.

ANSWER : Hello. Thank you for writing in. A vehicle being that new should not have any kind of warning lights. If you think there is an operator error, look to your owners manual for more information about the vehicle. This is your best source for information about the way the vehicle is designed to perform. You likely have a warranty that will cover this. The burning smell is a definite sign that there is an issue. Even with an operator error, the engine should be fine. The parking brake however may be an issue. Make sure she is disengaging it. The engine only having 200 miles on it, is not broken in yet. The engine works best after around 1,000 miles. For an inspection into what the check engine light is trying to tell you, contact our service department.

ANSWER : Hi there. If the coolant reservoir is bubbling before the coolant is hot and before the engine begins to overheat, then there could be an issue with the head gasket. If there is a combustion gas leak in the cylinder and the head gasket is the cause, then exhaust gasses will enter the cooling system and cause excessive pressures and cause the system to boil before it’s even hot. Get a block tester from a local parts store and use the tool to check the vapors on the cooling system to see if there is exhaust gases in the cooling system. If there is exhaust gases in the cooling system, the chemical that is blue in color will change to a green or yellow color as you plunge the tool and suck up the air above the inlet spout to the coolant reservoir. If that is the case, then the head gasket will need to be replaced and the cylinder head will need to be checked for any cracks. If there is no exhaust gases in the cooling system, then there is excessive air in the system and could be caused by a failed water pump. If you need further assistance with your cooling system bubbling, then seek out a professional, such as one from Your Mechanic, to help you.

ANSWER : Hello there, you have a long series of issues going on with your 2013 Hyundai Sonata. If you keep getting a repeating oil light on than there is likely a fault in that system.

Since this fault has lasted after the engine was replaced it could be a oil pressure sensor, wiring harness fault, ECU fault, oil pump, oil strainer clogged, or low oil pressure.

To diagnose this issue properly you need a complete vehicle inspection to start from square one and identify the root cause of all this.

ANSWER : Hello. It sounds like you may have an issue with your throttle position sensor. This sensor sends a reference voltage to your power-train control module, which uses that to determine ignition timing and fuel trims. If the power-train control module is not detecting the proper signal from the throttle position sensor, the engine may not accelerate properly. It’s probably a good idea for you to have a professional mobile mechanic come to your location and complete a car is slow to accelerate inspection first, so they can pinpoint what is causing this issue to occur and they will recommend the right repairs be completed.

ANSWER : Hi there. If there is carbon build up on the valves in the engine then that can cause a rough running condition and even a check engine light but that will not usually cause the vehicle to stall. It sounds like you have another issue going on here. From my experience with this vehicle most of the time this is caused by a voltage issue. Most of the time it is a loose or dirty ground connection or an issue with the ignition switch. I usually start by scanning the computer for codes to see what is coming up as that can assist in finding the issue. If the codes do not help then the electrical system would need to be diagnosed to see where the power is being lost.
