According to the firm's investigation, a defect in the DENSO fuel pump installed in the affected Toyota and Lexus vehicles leaves vehicle owners at risk of spontaneous vehicle shutdown, engine stall and other safety risks that increase the likelihood of a crash or injury.

Many owners of affected vehicles have taken to online forums and NHTSA (the National Highway and Transportation Safety Administration) to report complaints pertaining to the DENSO fuel pump defect:

  • "2019 Highlander XLE loses power, unable to accelerate, & jerks and stalls in traffic. Bought at 200 miles, certified preowned. It is a nightmare vehicle."
  • "Almost got hit this time, man behind me coming fast and had to swerve into lane over to miss me. This car is going to kill me or someone by causing an accident if they do not get it fixed right."
  • "First time it stalled it started to lose power put -put and chug like jerking and all dash and electrical on dash went out, unable to accelerate, then stalled out in road, unable to steer or control vehicle."
  • "I have had constant problems with my 2018 Camry since purchasing May 2018. My car is always jerking as I accelerate and when I'm driving in town, feels like I'm getting rear-ended and hesitating on highway when I have to accelerate into traiffic [sic] which is very dangerous when the car won't get up and go."


The low-pressure fuel pump is an integral component of safe vehicle operation, and the affected Toyota and Lexus models suffer from a fundamental design flaw that causes the fuel pump to prematurely fail. As Toyota admitted, the impeller in its low-pressure fuel pump absorbs fuel and water, causing it to degrade and deform. The deformed impeller comes in contact with the fuel pump body, creating excess running resistance, causing “illumination of check engine and master warning indicators, rough engine running, engine no start and/or vehicle stall[ing]...” according to reports.

When the fuel pump fails, gasoline is not supplied to the engine, causing reduced engine power, stalling, and/or engine shutdown. Compounding the problem, the fuel pump defect occurs spontaneously with no advance warning to the consumer, thereby creating an extremely dangerous condition for drivers and occupants.


Hagens Berman believes that consumers have the right to replacement costs of vehicle parts and deserve compensation for Toyota's failure to sell them a safe vehicle. Consumers deserve answers and have rights under the law against Toyota for having sold a defective vehicle that put them at risk of injury or death.


Hagens Berman is one of the most successful auto litigation law firms in the U.S. and is presently leading nationwide cases against major automakers for emissions-cheating, safety defects and negligence, and your claim will be handled by attorneys experienced in automotive consumer law. The firm also brought a record-setting automotive litigation case against Toyota for its sudden unintended acceleration defect, achieving a $1.6 billion settlement for vehicle owners.


There is no cost or fee whatsoever involved in joining this case. In the event Hagens Berman or any other firm obtains a settlement that provides benefits to class members, the court will decide a reasonable fee to be awarded to the class' legal team. In no case will any class member ever be asked to pay any out-of-pocket sum.
