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.

A contrarian, Matt claims to prefer understeer — stating that front and all-wheel drive vehicles cater best to his driving style.

    "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!


  • Steve Jacobs I've got a bright Red Kia EV6. Easy to find in a parking lot.
  • MKizzy Gently used EV6's under $30K aren't hard to find and have the range and style to almost intrigue me into taking the EV plunge. However, I'll wait for a mid-sized non-luxury EV sedan or wagon which is not a tablet housing a car (Model 3) or sacrifices too much usable space for the sake of style (Ioniq 6) before I go electric. I'm not holding my breath.
  • Arthur Dailey Am currently comparing both vehicles. Some issues not addressed in the article 1) the wait times for most RAV4's are currently considerably longer, 2) RAV4's are among the most stolen vehicles in my area (the GTA), 3) Mazda has a superior warranty. Manufacturing locations are perhaps a toss up. For the majority of these vehicles sold in the Canadian market from what I can ascertain, CX-5's are manufactured in Japan, and RAV4's in Alliston Ontario. One area where I will disagree with Matt is in the upholstery. I far prefer cloth to leather. With grandchildren and a dog, there is far more chance that the leather will be cut or scratched. And leather, particularly in black is too hot in the summer and very cold when you first sit on it during a Canadian winter. Cloth is the winner in that competition, but still an inferior choice to rich 1970's style velour upholstery.
  • Eliyahu I've had my 2018 CX-5 FWD top trim for about 18 months. It is fun to drive and a nice design. Mazda really did a great job of making the most out of the platform when they did the design refresh. The driver's seat, however, is overly firm and perhaps a tad too small. I have also come to appreciate the open feeling of the Forester compared to the well-organized but more closed in cockpit of the CX-5. A minor quibble would be the smallish gas tank. Overall, a very nice design.
  • Redapple2 CX5. Rented one 2 yr ago. ~2000miles. Issues. 1 Thumbwheel controller not good. 2. Sweeping curve on the interstate passing a car, the automatic braking picked up a car in the lane over. Beeps and slight braking. Not drop anchor mode, but still head scratching. But it looks so dam good. Wonderful still after many years. CX5 all the way!!!
