Toyota is an automobile manufacturer with a normally sterling reputation for the quality and dependently of its cars and trucks. However, this doesn’t mean that Toyotas aren’t without their known issues. If you remember back to the beginning of last decade one of the scariest problems Toyota had was with their cars unexpectedly accelerating. But even today, Camrys can have many different acceleration issues and problems.
Toyota Camry acceleration issues can present a variety of indicators such as lag, noise, and hesitation that stem from different problems, each has its own fixes. Depending on the warning signs the car exhibits, it could be anything from gears slipping to a full-blown transmission failure.
In the next sections, we will look at the most common acceleration problems Camry owners may experience. We’ll discuss how to identify specific acceleration problems using your Camry’s indicators. Once we know what the problem may be, we’ll outline some possible fixes that can be made to address your car’s acceleration issues.
Toyota Camry Won’t Accelerate
Nothing is more frustrating than a Camry that refuses to accelerate. Not only does this make the car effectively unusable, but reoccurrence while driving can also be a major safety issue. A Camry that won’t accelerate may stem from a few distinct sources.
A Camry that won’t accelerate at all could be due to a variety of issues, this includes a lack of fuel, the parking brake is engaged, an actuator malfunction, sensor malfunctions, and other mechanical problems. Make sure to address the issue fully before attempting to drive the car again.
The easiest fix is if your car has simply run low on fuel without you noticing or your parking brake is applied. Everything else will require more involved diagnostic work and likely needs professional help to fix—unless you are mechanically inclined yourself. Below, we will look at each of these possible problem sources and posit some ways you can check yourself.
Actuators are electrical motors that provide several key functions in cars by synthesizing signals from your car’s components into various actions. They can contribute to acceleration issues as they are often used to build pressure and regulate flows in your Camry’s engine.
Possible Camry actuator issues include:
- Constant engagement of the actuator that provides pressure for brake pads.
- Premature failure to vital components due to excessive use or overloading.
- The spark plugs have gone bad.
- A fuel pump that is incorrectly functioning.
- Old or faulty wiring that is causing shorts.
If you think that your acceleration issues stem from actuator faults it is best to get a diagnostic test done by a reputable mechanic.
For modern cars, the computing power onboard is as important to its functioning as horsepower can be. Nowhere is this more apparent than in the myriad of sensors present in your car. The malfunction of some of these sensors can harm your Camry’s ability to accelerate.
Possible Toyota Camry sensor malfunction problems can include:
- Sensors that are damaged and would prohibit acceleration, such as the oxygen flow sensor.
- An electrical fault in an integral area such as a crankshaft sensor.
- Miscalibration such as would cause the throttle position sensor to fail to read an accurate position.
- Malfunctioning of sensors for the electronic fuel injector (EFI) system.
In addition to the above causes, your car may have issues with wear or breakage of mechanical parts such as the input shaft or your transmission’s band or clutch packs. For this reason, it is best to get your Camry checked out by a professional unless you really know your way around your car’s internal structure.
And of course, if you suspect a safety defect may have occurred, check to see if a recall has been issued for your make and model, and be sure to file a complaint with the NHTSA right here.
Toyota Camry Acceleration Hesitation
Acceleration hesitation is a common problem experienced by many Toyota Camry owners. Hesitation during acceleration can be identified by the diminished ability to accelerate due to accompanying shuddering or shaking that takes place during the process. If this happens and the road conditions are otherwise good, it can be indicative of a larger issue with your car’s acceleration.
Camry acceleration hesitation can be diagnosed by frequent shuddering, halting, or shaking when the accelerator is pressed. It can be caused by many distinct issues including lack of lubrication, gears slipping, transmission issues, clogged filters, or braking system errors.
If your Camry experiences acceleration hesitation, consider looking into the following:

- If the car’s brakes are engaging during acceleration due to human, mechanical, or sensor error.
- Your car’s fluids are topped off, as a lack of lubrication in key components can lead to shaking and shuddering during acceleration.
- Airflow obstructions due to filters that are clogged or over-taxed.
- If you hear clicking or whirring before your car seems to catch and begin to accelerate, you may have an issue with your gear changer or gears slipping.
- Other transmission issues such as failures with the torque converter or valve body can be a prime culprit of acceleration problems characterized by marked hesitation.
The simplest fix is often to make sure that your car’s fluids are properly topped off, this can include motor oil as well as brake and transmission fluids. If this doesn’t seem to fix the issue the problem may be more systemic and will most likely involve a visit to your local mechanic.
Toyota Camry Acceleration Noise
What if your Toyota Camry still is able to accelerate but produces an unexpected noise while doing so? It might be tempting to ignore sounds as long as your car still functions otherwise as usual but doing so can only cause larger problems down the road if left unfixed.
Excess noise during acceleration can be caused by a variety of issues that may stem from engine fatigue, lack of maintenance, muffler problems, or larger transmission issues.
Toyota Camry Acceleration Delay or Lag
If when you press your Camry’s accelerator there is a noticeable delay in acceleration, you should look into the issue immediately and, if possible, stop driving the car until it is resolved. This is because a delay in acceleration can be dangerous to you and other drivers on the road. Such lag may also be a sign of larger issues that may come up if the problem remains unfixed.
Toyota Camry acceleration delay and lag are often caused by issues that are similar to acceleration hesitation. A delay in acceleration may be caused by brakes sticking, a bent axle, transmission issues, tire problems, sticky wheel bearings, loose motor mounts or lugs, vacuum and air filter clogs.
The reason why your particular car is lagging during acceleration could be one or a combination of the above issues. The fix could be as simple as replacing or balancing bad tires or wearing-in sticky brakes.
If you have recently been in an accident, you could be witnessing knock-on effects such as a bent axle. Clogged air filters are also a prime suspect and should be replaced if warranted after inspection.
Toyota Camry Hybrid Acceleration Problem
A Hybrid Toyota Camry can have acceleration problems specific to its type. While not due to their hybrid nature necessarily, the set of issues and problems can be distinct from those of a conventional Camry.
Hybrid Toyota Camry acceleration issues can include everything that may go wrong with a standard Camry, with additional considerations that must be made due to the hybrid nature such as issues with driving assist modes or a lack of constant power provided to the engine.
In general, the issues that can plague a hybrids acceleration ability can be reduced to differing shift settings applied by onboard computers to hybrid vehicles, a malfunctioning knock sensor, or a brake actuator failure. Some drivers have reported the situation improves after using top-tier fuel for a tank or two.
Another solution is to take the car to your Toyota dealer and see if they can perform a software update or otherwise diagnose the problem.
