Washington, D.C. – April 22, 2025 – The U.S. government auto safety regulator has upgraded and expanded its investigation of Honda (NYSE:HMC) cars that may stall and not restart.
The investigation comes on the back of close to 1,300 complaints and could lead to a recall of roughly 2.2 million vehicles, including:
- 2015 – 2025 Acura TLX
- 2016 – 2025 Acura MDX
- 2016 – 2015 Honda Pilot
- 2018 – 2025 Honda Odyssey
- 2019 – 2025 Honda Passport
- 2020 – 2025 Honda Ridgeline
Recall summary
The regulator, the National Highway Traffic Safety Administration (NHTSA), originally opened an investigation on June 3, 2022, following more than 200 complaints regarding Honda Passport SUVs that would fail to restart.
This would happen after the vehicle came to a complete halt and the start-stop system automatically shut off the engine to enhance fuel efficiency.
In January 2023, Honda issued two service bulletins, instructing dealers how to deal with this problem. But this remedy proved insufficient, with many cars reportedly still stalling even after being repaired.
The investigation has now been upgraded to a so-called engineering analysis. This means that the investigators will conduct a deeper analysis to assess the effectiveness of the repairs done so far. In addition, the scope of the investigation has been widened to add more cars that were included in the service bulletins, as well as some newer models.
Recall risks
A stationary car may get hit by other vehicles, especially if the defect occurs in dense traffic, increasing the risk of an injury.
In fact, this investigation comes on the heels of four crashes and two injuries. Fortunately, no fatalities have been reported.
Dangerous situations
A driver complained that her 2016 Honda Pilot “has stalled several times on the busiest highway in Hawaii during rush hour traffic”. The person had to put their car in Park and wait at least 30 seconds for it to restart “in the middle of a [busy] highway.”
Another driver expressed that he feared that he was going to be “killed” in the car if it did not stop losing power. Honda apparently advised him to leave the vehicle in “moving traffic” to “film” the problem, further adding to his worries.
What is a service bulletin?
A service bulletin is a step below a recall where the car maker lets dealers know about how to fix a common, recurring problem that does not represent a serious safety issue. Unlike in a recall, dealers are not required to proactively reach out to drivers.
