Chevy Malibu   Alleges Engine Power Reduced Defect

Chevy-Malibu-Alleges-Engine-Power-Reduced-Defect-Top-sAccording to a class action lawsuit filed by General Motors, Chevy Malibu cars have an engine fault that causes them to lose power suddenly.

Thousands of Chevy Malibu cars from 2016 to 2018 are said to have a faulty electronic throttle control and accelerator pedal position sensor.

The electronic throttle control system is in charge of regulating the vehicle’s engine by electronically linking the accelerator pedal to the throttle.

These components are said to be faulty, causing the Chevy Malibu cars to lose power abruptly, “frequently at interstate highway speeds.” The dashboard display in certain vehicles may display a “Engine Power is Reduced” warning.

Plaintiff Mark Rothschild bought a 2017 Chevrolet Malibu in September 2017, according to the GM engine fault class action. Rothschild’s car reportedly flashed a “Engine Power is Reduced” warning in March 2018 while traveling at highway speeds, reducing speeds to approximately 20 mph.


According to the GM class action, “Mr. Rothschild fortunately maneuvered his car to a safe location out of traffic but worried for his safety.”

According to reports, Rothschild took his car to a GM shop and had the accelerator pedal rebuilt under warranty. However, Rothschild’s car reportedly had the problem again a year later.

The dealership reportedly refused to pay for the repairs this time. Rothschild claims he protested to GM corporate but received no help. In the end, Rothschild was allegedly forced to spend almost $200 for a separate technician to repair his accelerator pedal.

In July of this year, Rothschild encountered the problem once again. He returned the car to the technician for a third time, this time under warranty, and had the pedal replaced.

The GM class action alleges that Mr. Rothschild has never been reimbursed for his out-of-pocket expenditures or lost time spent trying to get the Engine Power Reduced issue fixed.


Several customers are said to have complained about the engine issue and decreased power. According to these allegations, GM was aware of the issue but neglected to notify customers or recall the car components. GM is accused of concealing the problem rather than notifying customers.

According to the GM class action lawsuit, “despite its knowledge, GM has refused to recall the intrinsically hazardous electronic throttle control and/or accelerator pedal position sensors or compensate vehicle owners for the eventual failure of this crucial part.”

Rothschild’s GM class action aims to represent a group of customers who bought or leased a Chevrolet Malibu between 2016 and 2018. He also aspires to represent a subset of the same New York customers.

Actual damages, statutory damages, punitive damages, disgorgement, restitution, interest, court expenses, and lawyers’ fees are all sought in the GM engine fault class action case.
