The Toyota Supra is the brainchild of the Toyota Motor Corporation and has been in production since 1978. Toyota stopped selling the Supra in the United States in 1998 and ceased production entirely in 2002. In this post, we bring you common Toyota Supra faults .
After a hiatus of nearly two decades, the Toyota Supra returned in 2019 to critical and commercial acclaim. It immediately became one of the highest rated and most sought after sports cars in America.
Common faults of the Toyota Supra
Although after its return it became one of the most sought after cars, there have been some complaints about the functionality of the Toyota Supra, and that is really what this article is about. Let’s get down to business.
1. Steering wheel tremors
One of the most common Supra problems is a malfunctioning steering wheel. There have been several complaints about the steering wheel shaking when the brakes are applied and it has become a source of great concern for many owners.
Possible causes and solutions
How about we look at all the reasons why this may be happening, as well as suggest optimal solutions?
1- Unbalanced tires
This is one of the most common reasons why steering wheels shake and shake. If the tires are misaligned, they will send jolts through the car’s system all the way to the steering wheels.
However, we must mention that if this is the reason for the problem, it is likely that you experience the shaking while accelerating.
If you are sure the tires are properly inflated, check the treads on the tires. If they are uneven, shaking is unavoidable, and you may need to rotate or replace them. That is subject to expert evaluation.
2- Defective brake rotors
If the steering wheel shakes a lot while driving, it’s probably an indication of a bad brake rotor . Either the rotors are completely worn out, have lost their shape, or have been installed incorrectly.
It could also be a problem with the brake pad or the entire braking system, and it would help if you investigated it as soon as possible.
3- Problems with suspension components
Unusual tremors in the steer wheels while driving could also be the result of problems with the suspension components. This is more likely to happen with very old cars because they often have worn tie rods.
We understand how scary and unsettling it is when your steering wheels suddenly start shaking. It could be for any of the above reasons, but before taking any action, we advise discussing these symptoms with an expert so that they can examine the car and come up with a concrete solution to the problem.
2. Loss of power
Many Supra owners have complained about the vehicle’s noticeable loss of power and rough operation. Some owners suspect a problem with the Supra’s exhaust system.
Owners have also noticed that the power problem often arises when the engine is restarted within a few minutes of turning it off.
Possible causes and solutions
Here are some reasons why your Toyota Supra may be losing power:
1- Clogged fuel filter
Fuel filters take on the noble responsibility of removing impurities from gasoline to block its entry into the engine. However, if the fuel filter is clogged , it allows contaminants free entry, ultimately resulting in a loss of power.
This is precisely why it is important to change and check filters regularly.
2- Obstructed exhaust
The Toyota Supra has an exhaust system that helps reduce the amount of pollution from the fumes. However, if the tube becomes clogged, it could weaken the engine and ultimately lead to a loss of power.
3- Clogged air filter
Like fuel filters, air filters protect from debris, dirt, allergens, and other contaminants. However, if filters are not cleaned regularly, they end up becoming hostages to the debris they are trying to avoid. The end result is loss of engine power.
If you own a sports car like the Supra, there’s no way you’d be comfortable with your car randomly losing power. For this reason we advise taking the car to a trusted mechanic if you have this problem.
In addition to that, you should also have a maintenance and service plan for your car. That’s one of the best precautions you can take to prevent the problem.
3. Thick white smoke from tailpipe
Going out for a spin in your car and watching it go crazy while exuding thick white smoke is not a great experience. Unfortunately, this is one of the most commonly reported problems with the Toyota Supra.
Many of the owners who complain about this have also reported that they notice the car overheating for no reason.
Possible causes and solutions
Here are the possible causes of thick white smoke coming from the exhaust of your Toyota Supra:
1- Broken stock
Cylinder heads, by their very composition, are vulnerable to cracking at some point. When this happens, coolants leak out and contaminate the engine oil, resulting in white smoke coming from the tailpipe.
2- Cracked head gasket
The head gasket is a seal between the cylinder head and the block, which serves to prevent coolants from reaching the engine cover. However, the head gasket tends to become damaged and worn over time, and its failure precipitates white smoke and overheating quite a bit.
A blown head gasket cannot be successfully repaired; you’ll have to get a spare.
3- Cracked engine block
Another reason for the thick white smoke coming out of the Supra’s exhaust is a problem with the engine block. Now, this is very unlikely, especially if your car is new or recent; however, it is a possibility.
Engine blocks are supposed to withstand extreme heat and keep it from reaching the most fragile components. However, if any of the engine components are faulty, it could bring the entire process to a standstill.
Aside from white smoke, other symptoms of a blown engine block include overheating, discoloration of coolants, and poor vehicle performance, among others.
There is no other way around it other than replacement, which is best done by a professional.
If you have thick white smoke coming from your Supra, take it to an expert for a proper diagnosis. In this way, you can be sure of what the problem and the solution really are.
4. The car stops regularly
We also found a number of complaints related to the Toyota Supra randomly stalling. Many Supra owners are concerned, and some have even noticed that it occurs after the engine has warmed up.
Possible causes and solutions
These are some of the possible reasons why the Toyota Supra stalls:
1- An empty tank
It goes without saying that a car doesn’t work properly when it has an empty or almost empty tank. If your car has stalled, you may want to make sure this is not the case.
2- A faulty EGR valve
The exhaust gas recirculation valve serves to reduce the pollutants emitted by the Toyota Supra. Like all other components, the EGR valve can develop malfunctions , and when it does, it can cause your car’s engine to stall.
You may have to clean or replace it, and of course, the latter costs a lot more money.
3- Hot coolant sensor
The Toyota Supra has a component known as a coolant temperature sensor. Its job is to measure engine coolant temperature and send a signal to regulate fuel injection and engine timing.
If the coolant sensor fails, it could cause the engine to overheat, stall or knock.
If the car has stopped for reasons other than an empty tank, we recommend that you go to an expert to carry out a diagnosis.
The good and the bad of the Toyota Supra
You already know the common faults of the Toyota Supra, however, it is also good that you are aware of the good things that this car has for you.
The following are some pros or good points of the Toyota Supra:

What do the reviews say about the Toyota Supra?
The comments and opinions about the Supra are very good, among them the ones that stand out the most are the following:
“Is this automotive miracle worthy of the Supra name? Of course. It reinvents the concept in a way that makes sense for today’s world, and is offered at a price… that is a relative bargain when measured against its predecessor and competitor Porsche.”
It is a very complete coupe. Big enough inside, well equipped, handsome, fast and good-natured. It is adult, but compact, agile and smooth. It’s a clever piece of engineering. A car you’d enjoy driving anywhere, a car that probably achieves the best compromise of GT and sportiness of any car in its class.
