Facing problems with the incredible Toyota RAV4 is something you never wanted. However, just like any machine, the functions of the Toyota RAV4 can go wrong.
A few issues may just surface after using the car for a definite period.
Here, the hybrid system malfunction RAV4 is a scenario you have to attend to.
There are 3 reasons for hybrid system malfuntion of RAV4. Those are overheating the internal system, dead battery, and sensor issues. The solutions are simple when you have to cool down the car or replace the battery. Reprogramming the hybrid data is also essential.
In this context, we invite you to take a deeper look at the different scenarios. All you have to do is invest some time and effort in the fixes.
3 Reasons Behind RAV4 Hybrid System Malfunction
The hybrid system malfunction may arrive from many different angles. The 3 main reasons would signify the angles in an elaborate manner.
A RAV4 pre-collision system malfunction means some of the internal functions are not working. The hybrid system of the vehicle would notify the driver about the issues.
Suddenly the warning lights may turn on during driving. You have to stop the car right away when it happens. Here’s someone who faced the same issue!
Without stretching much, let us dive deep into the reasons.
Reason 1 of 3: Internal System Overheating
Different hybrid Toyota models can react differently to external climate temperature. In this case, RAV4 prime hybrid system malfunction can happen due to the hot climate.
It has probably been a long time since you are speeding on hot roads. The radiators may stop functioning while the engine overheats. This is a serious scenario to look at.
Basically, as time goes by, the internal parts may start to corrode. The depreciated part does not respond to the cooling methods.
Solutions such as bypassing the heater core may not work as well. In fact, it can just do the opposite for you. Furthermore, the internal functions may make your vehicle shake while running.
Surfacing issues in one area can give rise to issues in other areas.
Solution: Complete Internal Cooling
You might be wondering about the specifics of pre-collision system malfunction and how to fix it. The fix is easy as you have to cool down your engine and other internal functions.
Normally, when the engine is cooled, the other parts may just respond successfully.
The main idea of the cooling system is not to make the engine go cold. A cold engine won‘t work, all you have to do is set the right temperature. The perks of the engine cooling system are that it will make the cylinders work efficiently.
An important point to outline is to find out how the car cooling system works.
The cooling system works when coolant is injected into the internal system. The coolant passes through the water pipe and radiator to absorb heat from the engine. The coolant fluid would make the cylinder push through, allowing the system to cool down. The heat will be balanced by the engine.
So, to fix the issue you need to add coolant and see for leaks. If there is any leak, you need to replace the coolant container. Some of the best coolant for RAV4 are listed below.
The most compatiable coolant for RAV4 is Zerex Asian Vehicle Coolant. You can check the price on Amazon.
You can also go for Valvoline Multi-Vehicle Coolant. You can check for availability on Amazon.
Another alternative is ACDelco Engine Coolant. You can check the price on Amazon.
Now, let us look at another reason.
Reason 2 of 3: Dead Battery
A battery can go dead after 5 to 6 years of operating. Generally, the battery would lose its function after about 100,000 miles of driving.
However, an overheated engine can heat up the battery as well. In this situation, the battery can go dead before reaching the 100,000 miles driving milestone.
The charging system malfunction Toyota RAV4 can cause the battery to go dead fast. Here, the vehicle is not able to charge the battery properly. This means the battery would go dead sooner than expected.
As mentioned before, the internal wires and cables are overheating and defaulting. As electrical issues surface in your car, the battery charging system would default.
You won’t be able to start the engine in this aspect.
Solution: Replacing The Battery
Replacing the dead battery is an easier deal than you think. You can do it at the garage with the help of professionals. Or perhaps you can do it alone, to mainly save cost.
You might be wondering how to reset the pre-collision system malfunction. This is because the user manual would ask you to reset the functions. This is before replacing the dead battery.
There are positive and negative terminals in your battery. All you have to do is disconnect them. After that, you would remove the bolts and thus place the new battery in.
Screw the bolts and then connect the two terminals. You are good to go!
Reason 3 of 3: Problems With The Sensors
At any time when the car overheats, the sensors may not work efficiently. Normally, you would face trouble with the transmission lines while driving.
A non-responsive sensor is one of the main reasons behind hybrid system malfunction RAV4. Sensors may lose functions when the lineups default due to corrosion or overheating.
In this scenario, the entire programming of the computer may lose data. The data that makes the car move goes away causing the system to malfunction.
It has been recorded that the Prius Prime hybrid system malfunctioned due to a loss of data. The Prius Prime model programming setup is more complex than others. It has been seen that complicated programming has backfired.
Solution: Reprogramming The Hybrid Data
Have you ever asked what hybrid system malfunction means? This means that the sensors must be reprogrammed. This is one of the three solutions indicated here.

Hello and thank you for taking questions so seriously. I too share the passion you spoke of however my focus is mainly on improving the performance of vehicles. However I’m this case I’m a little bit stumped and Very Concerned! My wife has a 2021 RAV4 Hybrid xle model with around 60 thousand miles. It was recently in a minor fender bender and currently has a damaged active air grille shutter or radiator grille shutter, which has put a constant message stating the damaged shutter and to visit the dealer. Today 3/5/23 I took it to the car wash and washed it myself. And when I went to leave after I was finished the vehicle wouldn’t recognize the key fob in range and instructed me to touch the start/stop button with the key fob itsself. And then it started like normal. Only now there is 7 different malfunction messages in the message center, and on the dash between the gauges it is constantly switching from one malfunction message to another. All of which end with visiting the dealer. Which I would do if the vehicle even moved. It doesn’t even seem to engage in gear. But when it is in gear D or R it hangs up when you press the throttle as if the parking brake is engaged. By the way that is one of the malfunctions. Parking brake malfunction, along with hybrid battery malfunction avoid shifting to N, AWD system malfunction 2WD mode engaged, Pre-collision system Malfunction, and lastly It says braking power low and those messages appear in between the gauges and don’t stop coming. In the message center on the radio screen under vehicle alert history it has 8 different messages stating the brake, hybrid, parking brake,pre-collision, all wheel drive, electronically controlled brake, tire pressure warning, and vehicle stability control systems all displayed alerts on yesterday and todays dates.
I’ve been researching online and can’t find anything with All of these issues combined. I know the battery voltage is low. And the key fob battery was dead and had to be replaced but even disconnecting the 12v battery for over 30 mins. Both + and – didn’t have the slightest impact. My scan tool deletes the check engine code and they pop instantly back up. But on there it’s only 1 code. I’m lost and I really do NOT want to take this thing to the dealer. A few months ago my wife was 81/2 months pregnant with our now 6 month old daughter and for an oil change she was charged $180 and that was strictly for the 5 quarts of oil, the filter and the labor. Nothing else. Upon questioning the service writer he simply answered. It’s inflation. But since then the dealer has not even come near this vehicle. I’ve performed my own maintenance and would have already changed the shutter but I ordered the wrong part and cannot find one outside of giving the dealer the vin and having them order me 1. Sorry this is such a large message I hope you have the time to look at this for me and hopefully you have some helpful insight. I’m going to try the 12volt battery replacement in the morning and cross my fingers but I look forward to hearing from you Thank You
