[b]Toyota Corolla Problems – What Year Is Safe To Buy?[b]

March, 26, 2021

The Toyota Corolla is a line of subcompact and compact cars that have been produced and manufactured by Toyota and was first introduced in 1966. Back in the day, the Corolla was the best selling car worldwide, with the car model earning the best selling nameplate in the world in 1997. 20 years later, Toyota has reached an impressive milestone of 44 million Corollas sold over 12 generations.

Earlier models featured rear-wheel drive cars, while the more modern and recent models have been front-wheel drive. Four-wheel drive versions are also an option and have been produced throughout the generations, unbecoming direct rivals to the competition like the Nissan Sunny and the Honda Civic.

We start rating the Toyota Corolla with the ninth generation which started in August 2000, with the new generation coming out in mid-20001 with a fresh look and called the Corolla Altis. After the ninth generation, the tenth generation was introduced in 2006, and was called the Corolla Axio in the Japanese markets.

The eleventh generation was produced starting in May 2012, with the new option now available in either a 1.3-liter or 1.5 four-cylinder engine, and either in front or all wheel drive. The last generation we will discuss is the twelfth generation, which has been produced since 2018 and debuted at the Geneva Motor Show.

[b]Toyota Corolla Common Problems:[b]

Before we go through the problems of the Corolla year by year, we are going to do a general overview of the main problems in each category or generation of Corolla produced. By narrowing down the problems by generation, you can figure out the most common issues and how to fix the problems you might run into as a new car owner. Out of all of the generations, the more modern and latest generations have the fewest problems, and have the most minor issues.

[b]1: 2000-2005 Generation:[b]

Worn Piston Rings – one of the main problems of the Corolla is worn piston rings, which can lead to excessive oil consumption and possible engine failure, which can be quite expensive. Symptoms of worn piston rings include oil sludge buildup and low oil levels.

Airbag Control Module Failure – Regarding the 2003-2004 Corolla, the owners of these cars have had their front and side airbags deploy unexpectedly and not during intended use. The issues of the airbags related to the circuits in the cars short-circuiting from excessive noise, causing the airbags to deploy randomly.

[b]2: 2002 Toyota Corolla Problems:[b]

The Toyota Corolla had more problems listed than the previous eras, with the beginning generation having very few issues, and the problems really starting to crop up after the 2000 model year. The main categories of concern for the 2002 year is the engine, with the seatbelts and airbags category also having a high amount of NHTSA complaints.

Regarding the engine issues, the users complained the most about the engine using excessive oil, the engine failing, the tapping noise coming from the engine, and the buzzing noise occurring on acceleration. To fix the engine using excessive oil, the typical repair cost comes in at about $2,600 and occurs at around 97,000 miles.

[b]3: 2003 Toyota Corolla Problems:[b]

The main categories of concern for the 2003 year Corolla is the transmission, with the users having the most complaints regarding this system, and the most NHTSA complaints for the seatbelts and airbags. Owners have the biggest issues regarding transmission failure, the transmission and differential failure, the noisy transaxle at the transmission and grinding noise occurring. The price to fix the failing transmission is around $2,830 and occurs at around 116,000 miles.

The NHTSA lodged over 300 complaints regarding the seat belts and air bags category, with these issues resulting in 42 crashes, 44 injuries, and occurring at an average of around 72,000 miles. Users state that the airbag warning indicator remains illuminated, the car air bags do not deploy during a crash, and the airbag light turns on and off while driving.

[b]4: 2004 Toyota Corolla Problems:[b]

Regarding the following year of the Corolla, the engine is the highest problem category, followed by the interior accessories. Users have stated that the engine problems are most frequent regarding the ticking noise from under the engine, sludge building up over time, a clicking noise coming from under the hood, the engine not slowing down while braking, the engine light coming on, the engine light stalling while driving, excessive oil consumption, and the stuck starter pinion.

The interior accessories concerns focus on the broken door lock actuators, the center console door hinge breaking off, the rearview mirror and visor colliding, and the spring and hinge on the storage compartment breaking over time.

[b]5:2005 Toyota Corolla Problems:[b]

For the earlier model, the body and paint problems focus on the paint peeling, the water leaking into the interior, the paint peeling behind the rear wheels, and the trunk not being able to open. To fix any of these paint issues, the typical repair cost is around $540 and occurs at around 115,000 miles.

[b]6: 2006-2011 Generation:[b]

Premature Passenger Airbag Failure – when the passenger airbag goes off during a potential crash, there is a possibility that the airbag could rupture and cause metal fragments to hurt the occupants. This is due to the propellant degrading over time due to unstable temperatures and very high humidity levels.

Cracked Engine Control Module – the circuit board inside the engine control module in this generation of Corollas is more susceptible to cracks, causing harsh transmission shifting or the engine failing to start.

[b]2006 Toyota Corolla Problems[b]

For the 2006 model year, the engine problems had the highest amount of user complaints. The top reports of owner issues focus on the engine surging while stopped, the car cutting off while driving, the sudden unintended acceleration, the engine stalling out while driving, the engine failing, the car having a low idle, and the check engine light coming on.

TOYOTA COROLLA AND OTHER BRANDS

[b]Toyota Corolla vs. Mazda 3[b]


The Mazda 3, when compared to the Corolla, is a stronger and more performance oriented option than the Corolla. The Mazda’s engine is strong, agile, quick, and handles smoothly and engages quickly. In addition to the performance, the interior is upscale and luxurious. Both of these cars are available as sedans or hatchbacks, but neither one wins out in the passenger room category. The pro of choosing the Corolla is the driver assistance features and the better predicted reliability rating.

[b]Toyota Corolla vs. Honda Civic[b]


The Honda Civic is a well-rounded compact car that just beats out the Toyota Corolla. The Civic comes in various options, like the sedan, the coupe, and the hatchback body styles, giving you a choice of body style and engines for you to sue. The Corolla has a standard entertainment and infotainment system, while the Civic’s is optional and costs some more money.

However, some may argue that the Honda provides a more interesting and fun car to drive when compared to the Corolla. In addition, the Civic serves more interior space in the backseat and has a nicer and more luxurious interior, providing a more upscale look.

We all learn together.

you are right boss

The decision of whether to purchase a V6 or V8 car is largely a personal one.

The V8 engine offers more power but consumes more fuel. If you are undecided between the two, you will need a basic understanding of how internal combustion engines work.

Technological innovations have led to new additions to the combustion – like a turbo – and this has led to powerful four-cylinder and V6 engines.

These engines are cheaper than the V8 while enabling users to enjoy both power and fuel efficiency – critical for city roads.

History of internal combustion engines
V6 Vs V8 Car Engine Differences
Before the 19th century, the most common type of engines were steam engines. Things changed in the 1950s when fuel started being used as an energy source.

Researchers had experimented with other chemical compounds like hydrogen and coal but this was not successful. The first time people got to see a fully assembled internal combustion engine was in 1876. Nikolaus Otto created the Otto engine, which has been redesigned to give us what we see today.

The engine block is often made from aluminum or a cast iron block. Inside, you will find the cylinders arranged in one or two rows. Within the engine are water passages that are used to dissipate energy from the block and cool it in the radiator. Movement in the engine is due to the pressure produced by the ignition of air/fuel mixture.


The piston rings prevent the leakage of gases and oil into the crankcase. The camshaft will hold the inlet and outlet valves. The exhaust system will carry the exhaust gases through the tailpipe to the atmosphere. Problems can arise in the combustion chamber and this will be evidenced by white or black smoke from the exhaust. The spark plugs provide the necessary spark for the ignition of the fuel/air mixture. The crankshaft rotates as the pistons move.

Key differences between the V6 and V8 engine
1. Power decision
The internal combustion chambers use an air/fuel mixture to run the engine. Inside the combustion chambers are pistons that move up and down when the fuel/air mixture is ignited. This then drives the crankshaft and wheel axles.

A V6 engine has six cylinders while a V8 has eight cylinders. This means the V8 produces more power. Power means that the car accelerates at a faster rate. The V8 also has the added advantage of cylinder banks being in a perpendicular angle. Power delivery is smoother in the V8.


2. Fuel economy
Due to the additional cylinders in the V8, it means that it consumes more fuel than the V6. If you are thinking of using it for occasional city driving then it would be uneconomical to drive a V8. The V8 will also cost more than the V6. If you are looking for a car with less friction and maintenance costs then the V6 is better but if it is the power that you are after, then the V8 delivers.

Four-cylinder engine
The four-cylinder engine has been the most common type of engine and is the predecessor of the V6 engine. it is a compact engine that fits in most cars. Due to its lightweight design, it offers a smooth ride. The engines are also easy to work with because the cylinder heads are the highest point for the pistons.


The reason they have been widely used is due to the low manufacturing costs. Drawbacks include the inability to incorporate large cylinders like 2.5 or 3.0 liters and this limits performance. You also have a higher center of gravity and a rigid layout when compared to the V6 and V8.

V6 Engine
The engine is compact and rigid. You can have it as either a 2.0 or 4.0 liter. There has been an increase in the usage of the V6 engine as they act as a middle ground between the V8 and the four-cylinder. It offers more power than conventional engines and this has seen its usage in many fronts, rear, and all-wheel drives.

The drawback is that the use of two camshafts for SOHC and four for DOHC which makes the car heavier.


Most companies have drastically improved the performance of the four-cylinder engines by introducing turbo. This gives the car more power while enabling it to be fuel efficient. Turbo operation is simple – it works by adding more air to the chambers and this causes each combustion to have be more powerful.

This power is moved to the crankshaft and the car accelerates fast. The turbo is not in constant operation and is often deployed when the driver is in need of more power. This helps keep fuel consumption low.

V8 engine
This engine has to be a favorite for most muscle cars. It is an engine associated with power. The engine packaging is short and you get a good balance that is dependent on the crankshaft type – cross-plane or flat plane. The V8 rigid design offers higher displacement.


However, the V8 has several drawbacks like the engine being heavier than the V6 and it having a higher center of gravity than the flat engines. The costs of maintaining a V8 are higher due to the increased friction in the moving parts and this will push-up the purchase price.

Most of the cars with the V8 engine are either AWD or RWD which are restricted, unlike the V6 and four-cylinder engines that can be fixed on most car models. The V6 offers more displacement than the four-cylinder and has even been the preferred engine for most formula one cars.

Conclusion
When it comes to selecting either a V6 or V8 car, your budget, personal preferences and usage of the car will be a determining factor. If you are going to be using your car frequently for city traffic then it is wise you go with a V6 engine. The V6 engine can be mounted on most front and rear wheel drives while the V8 is mostly found in RWD and AWD cars.


But, if you are looking for more power at the expense of fuel efficiency then go with the V8 engine. You will have to contend with the additional maintenance costs when compared to the V6.
