Many times, despite your best effort, the car simply won’t go over a certain speed. Are you encountering such a problem?
Car won’t go over 10, 15, 20, 25, 30, 35 40, 45, 50 ,60, 80, 90 mph
Car won’t go over 10 mph:
In most cases, if your car isn’t even crossing 10 mph, it indicates that the engine is not getting proper fuel. Due to the same, the conversion process will not take place, and therefore your car won’t get enough power even if you’re pressing the accelerator pedal hard.
The most common cause of this is the dirty fuel filter.
When was the last time you checked the fuel filter of your car?
Most of us don’t, and that is the reason why it can get easily clogged, and when that happens, your car won’t go over 10 mph.
How can you fix it?
The solution to the clogged fuel filter is simple. You need to replace the fuel filter as soon as possible. It takes only a few minutes once you take it to the mechanic. The fuel filter is pretty affordable as well.
Car won’t go faster than 15 mph
When your car doesn’t even go over 15 mph, it is limping. In most cases, it is a problem with the car’s transmission system. If you continue to drive your car in that case, you might do more damage than good.
How can you fix it?
Since you are probably dealing with the transmission problem, the best way out is to take your car to a professional mechanic.
You have to find the nearest mechanic, and if the distance is greater, you have to call a tow truck. Only, in that case, you will not do any damage to the transmission system of your car.
Car won’t let me go over 20 mph
If your car isn’t able to cross 20 miles per hour, the fuel pump is faulty, or faulty spark plugs might cause the same.
In the case of faulty spark plugs, it doesn’t have enough power to make your vehicle travel at a faster pace.
If the fuel pump is the problem, once again, the compression happens at the reduced threshold, and therefore there is not enough power to make your vehicle go faster than 20 mph.
How can you fix it?
There is not much to do when the spark plugs are faulty, or the fuel pump is faulty. You will have to replace them.
To find the exact cause of the problem, you will have to consult a mechanic.
Fortunately, both of them can be replaced pretty quickly, and therefore you can continue your journey once you get them replaced.
Car wont go past 25 mph
When the car’s maximum speed is crossing 25 miles per hour, you will find that the problem is with the clogged catalytic converter. Due to this problem, the car might suffer from a fuelling issue or an ignition problem.
Both these can cause significant damage to the car. That is why, even if you’re driving locally, you shouldn’t continue driving your vehicle. You never know when it will break down fully or develop another snag that might be expensive and time-consuming to fix.
How can you fix it?
Unfortunately, you cannot fix ignition or fuelling problems yourself. Neither can you do anything about the clogged catalytic converter. That is why you have the option to take your car to the professional mechanic once again. You need to do so as soon as possible to prevent further damage.
Car won’t go over 30 mph:
When your car can’t go over 30 mph, it is most likely suffering from loss of power to the transmission system. However, the good news is that it doesn’t necessarily mean that you need to replace the transmission system altogether.
Once again, at the cost of sounding monotonous, you shouldn’t drive around your car even at 20 mph in that case.
How can you fix it?
Rather than taking your car to any mechanic, it is a good idea to contact the one who has handled transmission problems before. Most likely, it is a leak of the transmission fluid. However, diagnostic checks are needed and only a mechanic who has handled the transmission systems earlier would be able to do so.
Once the problem is detected, simply refilling the transmission fluid would do the trick.
Car won’t go faster than 35 mph:
Most likely, the problem is due to a malfunctioning sensor or component issue. That is why; your vehicle can’t attain speeds of higher than 35 miles per hour. However, if you consistently try to go over that speed, chances are the fuel consumption will increase, and the RPM reading might increase as well, but your vehicle might not travel at a higher speed.
How can you fix it?
Replacing a faulty sensor isn’t much of a problem. Your mechanic can do it right away. If there is a problem with some other component that might require some time to detect and replace.
If your vehicle has an onboard computer, the diagnostic and troubleshooting is easier, so you can detect the problem in no time.
Car wont go above 40 mph:
Truth be told, your car might not go over 40 mph for many reasons. It can be a problem with your car’s transmission fluid or the car going into safe mode due to the wrong reading by the sensor. It can damage a vital component as well.
The reasons can be quite a few.
How can you fix it?
First perform a diagnostic check. If your car has an onboard computer, performing such a diagnostic check is easy. You can refer to the car’s manual or refer to tutorials online to do so.
If you aren’t able to perform the diagnostic check, your only other option is to take the car to the mechanic.
Car won’t go past 45 mph:
Usually speaking, your car not being able to go over 45 mph means that it is suffering from a transmission problem or hydraulics issue.
Even if you are tempted to increase the speed beyond 45 mph, you won’t be able to do so. Only the RPM reading might increase.
In that case, the problem can be with the transmission fluid level, slipping bands, clutches, or hydraulic fault.
How can you fix it?
Only a mechanic can refill the hydraulic fluid and fix the clutch and the slipping bands. That is why such a problem can only be solved by a mechanic.
Car won’t go over 50 mph:
Two very common problems can cause this issue.
- The first one is the field clutch. In that case, you won’t be able to do much.
- Secondly, any problem with the electronic control unit of your car can also cause it to stagnate at 50 mph. In that case, the energy output of your vehicle will not increase beyond a certain level, and that is why it won’t be able to travel beyond 50 mph.
How can you fix it?
Hire a professional mechanic to deal with the field clutch. Also, if transmission fluid has been lost, the mechanic can refill that.
Problems with the electronic control unit might require a specialized mechanic. First, troubleshooting is needed, and only after that can the mechanic take corrective steps.
The good news is if there is a problem with the electronic control unit, there will be an error code that will help identify the problem quickly, and the mechanic can take corrective steps accordingly.
Car won’t go above 60 mph:
In most cases, when your car isn’t able to go beyond 60 mph, it is because the electronic control unit of your car is activating the limp mode. In very rare cases, it might indicate a mechanical problem as well.
How can you fix it?
The only way to solve the limp mode problem is to reset the electronic control unit. A mechanic would be able to do so in a short time. In case the car is activating the limp mode due to a faulty sensor, it might require replacement.
Mechanical problems can only be fixed by a professional mechanic, and you shouldn’t attempt to do so yourself.
Car won’t go over 80 mph:
At higher speeds, your car needs to use more fuel to accelerate. This is especially true when you’re shifting the gears frequently. In case there is a problem with the fuel pump, your car might not get enough fuel to attain a higher speed.
How can you fix it?
You will have to check the fuel pump. You can also check the fuel pressure regulator to ensure there is no debris blocking the fuel. If you check both these and they are okay, then only the mechanic can diagnose and fix the problem.
Car won’t go past 90 mph:
When your car isn’t going over 90 mph, and you hear a warning message or a warning beep, you have hit a speed limit.
Other than that, the cause of your car not going over 90 mph can be quite a few.
Thus, depending on the speed at which your car is not crossing, the causes can be different. Once you follow the guide above, you will know the cause, and after going through the solutions below, you can fix the problems.
How can you fix it?
Resetting the speed limit of every car is different. You can refer to tutorials online or your car manual to know how to reset the speed limit for your car.
If you discover that there is no speed limit set and still it isn’t going over 90 mph, a mechanic can help you out.
