Why did General Motors know about the shortcomings of their engines and did not let consumers know?

General Motors is about to ask for V8 engine. NHTSSA states that progress in vehicle security has contributed to increasing the annual number of lives saved in recent decades.

While vehicle security has recently improved dramatically, drivers are still experiencing serious defects in vehicles that can completely change their experience as owners.

One of these experiences is described in a lawsuit on February 18, 2025 before the US district court, the east of the Ostmichigan district, the South Division, in the name of the plaintiff James S. Powell II, which is to be certified as a collective claim.

“On October 22, 2022, the plaintiff (Powell) newly bought a GMC Yukon Denali 2023, which was produced by GM, with a V877 engine,” says the demand. Powell brought the vehicle to an authorized GM dealer after the engine checking light was switched on in 2024.

After the inspection, Powell was informed that the engine was defective and that it would be replaced by another. According to the demand, Powell continued to have problems with the new engine after replacement.

The demand also claims that vehicles that are equipped with the L87 -V8 engine have a “common defect in the storage of their engines, which are susceptible to failure, and have already done so, which leads to the break of the motor block through the pole or the engine grave”.

The NHTSSA retreat from April 24 shows a defect in “the components of the rod engine or the crankshaft in these vehicles … that can cause damage and motorhillers”.

In the lawsuit it is also said that “GM had known the engine error for several years, but did not inform at least 100 members about the collective claim that GM vehicles were rented or bought.

In the lawsuit, numerous consumer complaints are given that the National Road Traffic Safety Administration (NHTSA) were presented with in relation to vehicles with the L87 V8 engine.

He states that “it is undeniable that GM was aware of the motor error before March 24, 2023”, years before checking the review. A similar demand was submitted in Georgia in early April.

When GM was asked about the lawsuit, he said that it was not his policy to comment on ongoing legal disputes.

What to do if your GM vehicle is called for checking?

General Motors accepts the call to check very seriously, and adds individual attention to every L87 engine that reaches the dealers. When GM was asked for checking after the call, he said: “He will examine the engine and repair or replace if necessary.

Vehicles that exist on the inspection receive a larger viscosity oil that also requires a new oil filling cap, an exchange of the oil filter and a brochure of the operating instructions ».

If your vehicle is called for checking, you have to bring it to an authorized GM dealer in order to operate immediately and avoid possible engine problems. You can search for the check for your specific GM model with the vehicle identification number.

What does this retirement mean for GM?

Reliability is a major concern for those who buy cars. After all, nobody wants to deal with the car problems, especially if they can lead to expensive commissions for the mechanic or accidents. It is unfair to qualify GM vehicles unreliable, based on the retirement in question.

However, General Motors has different reliability values ​​for some of its best models. In contrast, according to a study by Iseecars.com, Toyota produces the five long -lasting cars.

In addition, the latest GM retreat has not been the only important retirement in recent years. In 2021, General Motors withdrew all Chevrolet bolt models due to a fire risk.

Fire reports in Bolt made this retirement even more stressful for the company and its consumers.

Should GM have already published its recent retirement?

There are many angry consumers who express their outrage in forums to solve the problems of the motor L87 V8.
