brake recall impacts 124 000 honda and acura vehicles

A handful of Honda models, and one from Acura, are under recall over a defect that could limit braking functionality. Impacted vehicles include the 2020-2021 Honda Civic, 2021-2023 Honda Passport, 2021-2022 Honda Pilot, 2020-2023 Honda Ridgeline, and 2020 Acura MDX.

A recall report filed with the National Highway Traffic Safety Administration (NHTSA) specifies improper assembly of the tie rod fastener that’s connected to the brake master cylinder and booster. Altogether, the recall encompasses 124,077 individual vehicles.

From the report:

The brake master cylinder may have been improperly fastened to the brake booster assembly during production, resulting in loose or missing tie rod nuts. During application of the brake pedal, a bending load may occur upon the brake booster assembly tie rod studs. As a result, the tie rod studs may break, leading to the brake master cylinder separating from the brake booster assembly and a failure to comply with Federal Motor Vehicle Safety Standards (FMVSS) 135 – Light vehicle brake systems.

Obviously, having the master cylinder separate from the brake booster isn’t going to improve anybody’s stopping power. Diminished braking performance is a given, with there being a possibility of a total loss of braking function. The report also states that there probably won’t be any warnings issued to drivers via instrumentation if something goes wrong.

It also blames the supplier, VBS, after Honda found a missing nut in 2020. VBS “implemented countermeasures” to ensure there were no additional defects. However, Honda received a quality report on brake failure in 2022 that encouraged the company to launch a full investigation.

VBS submitted part defect reports to the NHTSA earlier this year, followed by the serial numbers of the suspected parts involved in their recall as Honda continued its investigation. By June, Honda determined that a defect related to motor vehicle safety and FMVSS noncompliance existed and decided to conduct a safety and noncompliance recall.

At the time, Honda had received two warranty claims related to the issue between September 2022 to June 2023. There were no reports of crashes, injuries, or deaths related to this issue.

The manufacturer intends on issuing formal recall notices in August. But concerned owners can head over to the NHTSA recall website to determine whether their car is included in the recall campaign. Just be sure to have your VIN handy.

"December 2020 Honda manufacturing found a missing nut missing from the brake booster assembly tie rods and notified the component part supplier, VBS. VBS implemented countermeasures to prevent a reoccurrence. No outflow from the occurrence was found."
• What does that last sentence mean exactly? (Your individual spin is welcome)

  My guess is that Honda determined that none of the batch of parts had yet been installed in a car.

I'll give Honda props for getting after the problem, unlike a certain company headquartered in downtown Detroit in a certain cylindrical skyscraper with ignition switches!

Redapple2 jeffbut they dont want to ... their pick up is 4th behind ford/ram, Toyota. GM has the Best engineers in the world. More truck profit than the other 3. Silverado + Sierra+ Tahoe + Yukon sales = 2x ford total @ $15,000 profit per. Tons o $ to invest in the BEST truck. No. They make crap. Garbage. Evil gm Vampire
Rishabh Ive actually seen the one unit you mentioned, driving around in gurugram once. And thats why i got curious to know more about how many they sold. Seems like i saw the only one!
Amy I owned this exact car from 16 until 19 (1990 to 1993) I miss this car immensely and am on the search to own it again, although it looks like my search may be in vane. It was affectionatly dubbed, " The Dragon Wagon," and hauled many a teenager around the city of Charlotte, NC. For me, it was dependable and trustworthy. I was able to do much of the maintenance myself until I was struck by lightning and a month later the battery exploded. My parents did have the entire electrical system redone and he was back to new. I hope to find one in the near future and make it my every day driver. I'm a dreamer.
Jeff Overall I prefer the 59 GM cars to the 58s because of less chrome but I have a new appreciation of the 58 Cadillac Eldorados after reading this series. I use to not like the 58 Eldorados but I now don't mind them. Overall I prefer the 55-57s GMs over most of the 58-60s GMs. For the most part I like the 61 GMs. Chryslers I like the 57 and 58s. Fords I liked the 55 thru 57s but the 58s and 59s not as much with the exception of Mercury which I for the most part like all those. As the 60s progressed the tail fins started to go away and the amount of chrome was reduced. More understated.
Theflyersfan Nissan could have the best auto lineup of any carmaker (they don't), but until they improve one major issue, the best cars out there won't matter. That is the dealership experience. Year after year in multiple customer service surveys from groups like JD Power and CR, Nissan frequency scrapes the bottom. Personally, I really like the never seen new Z, but after having several truly awful Nissan dealer experiences, my shadow will never darken a Nissan showroom. I'm painting with broad strokes here, but maybe it is so ingrained in their culture to try to take advantage of people who might not be savvy enough in the buying experience that they by default treat everyone like idiots and saps. All of this has to be frustrating to Nissan HQ as they are improving their lineup but their dealers drag them down.
