The automotive industry is facing another significant safety investigation as federal authorities examine potential engine failures in popular Honda and Acura models. The investigation encompasses a wide range of units manufactured between 2016 and 2020, raising concerns about the reliability of certain engine components that could cause complete engine failure.
This development comes shortly after a previous recall affecting thousands of vehicles from the same manufacturer, highlighting the ongoing scrutiny of vehicle safety standards. The investigation’s scope and potential implications have drawn attention from both industry experts and vehicle owners, as authorities work to determine the full extent of the reported issues.
Investigation Overview
The National Highway Traffic Safety Administration (NHTSA) has launched a comprehensive investigation into potential engine failures affecting approximately 1.4 million Honda and Acura vehicles, according to a Global News report. The investigation focuses specifically on vehicles equipped with 3.5-liter V6 engines manufactured between 2016 and 2020. The probe comes in response to numerous reports of engine failures and related issues from vehicle owners. The investigation’s primary concern centers on connecting rod bearings, which play a crucial role in engine operation.
Affected Vehicle Models
The NHTSA’s investigation covers several popular Honda and Acura models from recent model years. The affected Honda models include the Pilot (2016-2020), Ridgeline (2017-2019), and Odyssey (2018-2020). For Acura, the vehicles included in the investigation are MDX (2016-2020) and TLX (2018-2020) models. These vehicles represent a significant portion of Honda’s and Acura’s lineup during the specified production years.
Technical Issue Details
The core issue involves the potential failure of connecting rod bearings in the affected vehicles’ engines. These bearings serve as crucial components that connect the pistons to the crankshaft in the engine assembly. The connecting rods are responsible for converting vertical piston motion into rotational motion that drives the wheels. When these bearings fail, they can cause catastrophic engine damage.
Previous Recall Connection
Honda had previously initiated a recall in November 2023 that addressed similar engine issues in approximately 250,000 vehicles. The current investigation examines vehicles that were not included in the earlier recall action. The NHTSA’s decision to investigate came after receiving additional complaints from owners whose vehicles were not part of the previous recall. The agency aims to find out if the earlier recall should have covered more vehicles.
Consumer Complaints
The NHTSA has documented a total of 173 complaints from vehicle owners who reported failures affecting the connecting rod bearing. These complaints were specifically from owners whose vehicles were not part of the 2023 recall. One significant incident among these complaints involved a crash, though fortunately without injuries. These complaints have prompted the agency to evaluate the full scope of the problem.
Warranty Claims Impact
According to Honda’s documentation from the 2023 recall, the company had received approximately 1,450 warranty claims connected to the bearing issue. These warranty claims provided valuable data about the frequency and nature of the issue. The high number of warranty claims indicated a potentially systematic issue requiring further investigation. The claims helped establish a pattern of failures that warranted regulatory attention.
Safety Risks
Federal safety regulators have identified a serious mechanical issue affecting the V6 engines in certain Honda and Acura models. The problem stems from potential malfunctions in the engine’s connecting rod bearings, which can cause the engine to stop working entirely. Safety records show that among the complaints received, there has been one accident reported, though fortunately without injuries. Federal investigators are now examining whether this issue extends beyond the vehicles covered in last year’s recall.
Investigation Details
The NHTSA has started a recall query regarding the engine bearing issues. The focus of the investigation is on vehicles not included in the November 2023 recall. The agency is particularly examining the 173 complaints from owners who reported connecting rod bearing failures. These complaints come specifically from owners whose vehicles were not part of the previous recall action.
Dealer Actions
According to the documents from last year’s recall, Honda instructed its dealers to conduct thorough inspections of the affected vehicles. The inspection process involves examining the engines for signs of connecting rod bearing failures. After the inspection, dealers were authorized to repair the engines when problems were found. In cases where repairs were not sufficient, dealers were instructed to replace the entire engine if necessary.
Vehicle Identification
The investigation covers vehicles identified by specific model years and manufacturing dates. Owners can verify if their vehicle is potentially affected by checking their Vehicle Identification Number (VIN). The NHTSA maintains a database where owners can search for their vehicle’s status. This information helps owners determine if their vehicle requires attention.
Safety Oversight
The federal safety agency is conducting this investigation to ensure all affected vehicles are identified and addressed. The investigation builds upon findings from the previous recall campaign. Investigators are particularly focused on units with similar specifications to those recalled. The goal is to determine whether additional safety measures are needed.
Previous Recall Actions
In late 2023, Honda took action by recalling a quarter-million vehicles that showed similar engine problems. During that recall period, the automaker documented more than 1,400 cases where customers sought repairs under warranty for engine bearing issues. Although the problem was widespread enough to prompt a recall, there were no injuries reported in connection with these mechanical failures. The recall process included complete engine inspections and necessary repairs or replacements.
Honda’s Response
The automaker has expressed its willingness to work alongside federal safety investigators to address these concerns. The previous recall campaign in November shows Honda’s awareness of the engine bearing problem. This new investigation focuses on additional vehicles sharing similar characteristics but weren’t included in the first recall. Safety regulators aim to understand whether the initial recall should have encompassed more vehicles.
Owner Resources
Vehicle owners have access to tools that can help them determine if their car might be affected by this investigation. The federal safety agency maintains an online system where owners can enter their car’s unique identification number for verification. This investigation specifically looks at Honda and Acura models produced between 2016 and 2020.
Investigation Scope
Safety regulators are gathering and reviewing reports of engine problems from multiple sources. This includes examining the history of repairs, documented mechanical failures, and owner experiences. The investigation team is particularly focused on understanding how often these failures occur. Their findings will help determine whether additional safety measures are needed.
