In a significant development for U.S. motorists, the National Highway Traffic Safety Administration (NHTSA) has escalated its probe into 286,000 General Motors vehicles amid growing concerns over engine failures. The move follows multiple complaints from vehicle owners, despite a recall earlier this year.

The safety watchdog pinpointed the root cause as potential defects in the engine bearings of GM’s L87 6.2-litre engines, found in popular models like the Chevrolet Silverado 1500 and Cadillac Escalade. The problem, if left unchecked, could result in engine damage or complete failure, heightening the risk of accidents.

From Preliminary Investigation to Expanded Analysis

The NHTSA first launched a preliminary investigation in January, which led GM to issue a recall in April. At that time, the automaker warned that defects in connecting rods and crankshaft components could compromise engine integrity.

However, new data has prompted the regulator to upgrade the probe to an engineering analysis. The agency has received 1,157 reports of engine bearing failures so far, prompting a closer look at vehicles both inside and outside the recall’s scope.

Implications for Vehicle Owners

Owners of affected GM vehicles are urged to monitor engine performance closely and follow recall instructions if applicable. Experts caution that engine bearing failures can lead to severe mechanical damage and costly repairs, underscoring the importance of prompt action.

As the investigation continues, the automotive community watches closely to see whether additional recalls or safety measures will be implemented to address the widespread issue.
