Mercedes-Benz vehicles equipped with M272 or M273 engines are equipped with defective gears that cause the vehicle to malfunction, according to a class action lawsuit filed in New Jersey federal court.
According to the Mercedes-Benz M272 and M273 engine class action lawsuit, these engines are equipped with defective gears in their balance shafts (in the case of the M272 engines) or with defective idle gears (in the case of the M273 engines) that wear out prematurely, excessively and without warning, causing the vehicle to malfunction, the “check engine light” to remain illuminated, and the vehicle to misfire and/or stop driving.
The only way to correct this problem, the lawsuit says, is to have the balance shaft or idle gear replaced, which is a large-scale repair job, costing customers thousands of dollars and leaving them without a car for weeks at a time.
The Mercedes balance shaft gear and idle gear class action lawsuit claims that internal company documents prove that Mercedes has known about these defects at least as early as August 2007, but has failed to take appropriate corrective action and has concealed the defects from unsuspecting owners and lessees.
“Mercedes has known all along about the existence of a defect with the balance shaft gears in its M272 engines and idle gears in its M273 engine, yet it has concealed that knowledge and deliberately omitted any information or dissemination about its existence,” the class action lawsuit says. “Mercedes’ concealment and its omission of any disclosure of the defect in the affected automobiles was not merely a case of innocent omission or misrepresentation, but rather represents an intentional campaign to fraudulently deceive the buying public.”
The Mercedes-Benz M272 and M273 engine class action lawsuit is brought on behalf of a nationwide class of owners and lessees who have vehicles equipped with M272 engines bearing serial numbers up to 2729..30 468993 and M273 engines bearing serial numbers up to 2739..30 088611.
The Mercedes M272 engine is reportedly installed in the following Mercedes-Benz vehicles:

I would like to join the law suit. The car just experienced a catastrophic failure while driving home on the interstate; violent shaking due to misfires in two cylinders and loss of power. Codes displayed are P0016 (crankshaft position, camshaft correlation bank 1 sensor A), P0300 (random/multiple cylinder misfire) P0303 (cylinder 3 misfire), P0306 (cylinder 6 misfire). Dead in the water – 2006 C280. 4matic, m272 engine.

I live in Canada, and I own a C230 2007 purchased in August 2006. Had purchased Extended Warranty that is 7 years or 140 KM. In September 2019 “Check Engine” light showed, Balance Shaft problem engine 272.
I filled a Claim in small claims Court against Mercedes Benz Canada Inc, providing a VIN for C230 engine 272; which was fitted with Balance shaft Sprocket made of HARD Metal on November 11,2006, my Car had only 4000+KM. Due COVID Shut downs, the case was only decided on 24 April 2022. MBCI claimed the Car did not have a hidden defect . the Judge did not consider any US Class Action Decisions as valid proof and I lost.
Please ANY help in Canada – Start a Class Action – How?
