Version 4

Safety Recall: 2007–11 CR-V Rear Frame Brace

Supersedes 23-032, dated May 16, 2023, to revise the information highlighted in yellow

 

AFFECTED VEHICLES

Year Model Trim VIN Range
2007–11 CR-V ALL Check the iN VIN status for eligibility.

 

REVISION SUMMARY

  • Under REQUIRED MATERIALS, touch up paint was added.
  • Under INSPECTION PROCEDURE, a video was added; step 7 and 11 was changed.

 

BACKGROUND

In salt belt states where de-icing agents are used to maintain the roadway, the de-icing agents, along with mud and dirt, could enter the rear frame through the rear frame drainage points. This de-icing mixture can accumulate along the rear frame, where it connects to the rear suspension trailing arm. Over time, accumulated de-icing agents/mud/dirt mixture may cause internal corrosion. As a result of this condition, the rear suspension trailing arm may detach/separate while driving, increasing the risk of a crash.

The vehicle may be deemed not repairable after an inspection, depending upon the condition of the vehicle and inspection results. Notify the customer prior to work being started.

 

CUSTOMER NOTIFICATION

Owners of affected vehicles will be sent a notification of this safety recall.

Do an iN VIN status inquiry to verify eligibility.

Some vehicles affected by this campaign may be in your new or used vehicle inventory.

Failure to repair a vehicle subject to a recall or campaign may subject your dealership to claims or lawsuits from the customer or anyone else harmed as a result of such failure. To see if a vehicle in inventory is affected by this safety recall, do a VIN status inquiry before selling it.

 

CORRECTIVE ACTION

Install the trailing arm holder kit.

INSPECTION PROCEDURE

Click here to view a video of the inspection procedure:

1. Put the vehicle on a lift.

2. Position the lift blocks under the vehicle’s front support points and rear support points.

 

NOTE: If the vehicle’s support points are compromised due to corrosion, please use best shop practices to lift the vehicle.

3. Raise the lift a few inches, and rock the vehicle gently to be sure it is firmly supported.

4. Raise the lift to its full height and inspect the vehicle support points for solid contact with the lift blocks.

5. Remove both rear wheels.

6. Place an under-hoist stand under the trailing arm for support.

 

7. Using an impact gun, attempt to remove the trailing arm front mounting bolt.

 

NOTE:

  • No punch testing is required. Any perforation noted near the trailing arm mounts is not a concern; the trailing arm is supported by the inner upper frame structure. Do not remove the trailing arm rear bolt.
  • If both the front and rear trailing arm bolts are removed, wheel alignment is required.
  • If the bolt does not loosen after attempting to use more force (i. e., higher torque impact gun, breaker bar) install the wheels.

Was the trailing arm front mounting bolt removed successfully?

YES – If successfully able to remove the trailing arm front mounting bolt, reinstall and torque the trailing arm bolt to 115 N·m (84.6 lb-ft) and continue to the repair procedure.

NO – If the trailing arm front mounting bolt spins freely without being removed or the bolt does not loosen, re-install the wheels and inform your Service Manager and/or Shop Foreman. The vehicle is not eligible for repair and the Trailing Arm Holder kit cannot be installed on the vehicle.

State on the Repair Order that the vehicle was not fixed and the issue remains. Have the vehicle owner sign the R/O acknowledging the inspection results and retain a copy of the R/O.

For trailing arm front bolts that do not loosen, take the required photos of the vehicle as shown in the

PHOTOGRAPH REQUIREMENTS section below. You will need to submit the photo files along with the warranty claim. Upload your photos to Tech Line using the Tech Line Image Uploader tool on the iN. Create a Tech Line contact using iN and with the access code contact Tech Line by phone to confirm receipt of the photos and vehicle inspection details.

For trailing arm front bolts that spin freely without being removed, a short 3 second video at (720P and 20Mb max) will be required. Email the video, VIN and the odometer photos to techline@ahm.honda.com and include “23-032 and VIN XXXX” in the subject line to provide the VIN number of the vehicle. Create a Tech Line contact using the iN and with the access code contact Tech Line by phone to confirm receipt of the video, VIN, photos and vehicle inspection details.

8. Repeat steps 6 and 7 on the opposite side.

 

PHOTOGRAPH REQUIREMENTS

9. Photo of VIN label on the left B-pillar.

 

10. Photo of the odometer reading (not the trip reading).

11. Photos of the failed trailing arm mount.

For trailing arm front bolts that do not loosen, take the following photos as shown below:

NOTE: The following photos are to be captured using the previously provided borescope Snap-on BK5600DUAL55eBay or any equivalent commercially available tool. The reference pictures below show the borescope entry locations and camera orientation, as well as examples of the stiffener inner structure.

Photo of the trailing arm mount collar.

 

Photo of the trailing arm mount nut.

 

For trailing arm front bolts that spin, take a 3 second video clip showing the trailing arm front bolt spinning. Video should be 720p resolution and under 20Mb in size.

 

NOTE: Video clip, VIN and odometer photos will need to be emailed to techline@ahm.honda.com, and include “23-032 and VIN XXXX” in the subject line to provide the VIN number of the vehicle.

 

REPAIR PROCEDURE

1. From the trailing arm holder kit, install the bolt guide wire around the threads of the 10×62 bolt. Then, insert into the frame insert washer.

NOTE: Make sure the engraving THIS SIDE UP on the washer is facing up.

 

NOTE: Due to an excessive layer of protected zinc (galvanized bolt), the 10mm nut is difficult to hand tighten. Before installing the guide wire clean the bolt threads. Use a 10mm x 1.25mm machine thread die or, if a tool is not available, use a socket or wrench to move the 10mm nut up and down the bolt (10×62) until the bolt and nut can be hand-tightened.

 

2. Insert the assembled bolt with guide wire and frame insert washer into the underbody opening.

 

3. Line up the brace.

 

4. Loosely install the rear trailing arm front mounting bolt (do not torque to spec).

 

5. From the underside, remove the bolt guide wire and hand-tighten the 10mm Use a downward force on the bolt (10×62) until it is loosely tightened.

 

6. Before tightening the underbody bolts, make sure that the brace is sitting flush against the wheel well in both directions as shown below.

 

7. Once the brace is positioned against the wheel well, torque the rear trailing arm front mounting bolt to 115 N.m (85 lb-ft) first, then torque the rear brace bolt to 38 N.m (28 lb-ft).

 

8. From the wheel well side, place the drill guide into one of the brace openings and use the 3/8 bit to drill into the wheel-well body. Drill both holes.

  • Use a vacuum to remove any metal shavings.
  • Apply touch-up paint around both drilled holes to prevent any new corrosion to the body.

 

9. Align the support bracket with the two bolts from the brace and place into the body. Then install the two 8mm nuts, and torque them to 21 N.m (15.5 lb-ft).

 

10. Repeat steps 1 through 9 on the opposite side of the vehicle.

11. Install the tires and lower the vehicle.

Chronology :

January 18, 2019
Honda submitted Foreign Recall Report 19F-012, informing NHTSA of a foreign recall in Canada for rear frame corrosion in certain 2007-2011 model year CR-Vs. After a market study of US market vehicles located in the Northeast region, Honda determined the rate of rear frame corrosion would not affect the structural integrity for the useful life of the vehicles due to fewer unpaved roads and lower sand/salt usage in the region as compared to Canada.

March 12, 2019
Honda received a market report on rear frame corrosion in the US market.

April 2019 – June 2019
Honda received additional claims for rear frame corrosion.

July 15, 2020
Honda repurchased a vehicle after observing rear frame corrosion and began to investigate the issue.

November 18, 2021
Honda expanded the investigation to focus on the accumulation of water/mud to the rear frame. Honda also continued a US market survey to investigate the potential of corrosion from de-icing agents.

March 6, 2023
Honda’s investigations confirmed the combination of water/mud accumulation to the rear frame and the increased use of de-icing agents in US salt belt states can cause rear frame corrosion rate equivalent to that for the recalled vehicles in Canada in 2019. Additionally, Honda identified the affected range of vehicles based on market occurrences and market survey results.

March 23, 2023
Honda determined that a defect related to motor vehicle safety existed and decided to conduct a safety recall.

As of March 23, 2023, Honda has received 61 customer complaints from the US market between September 2018 through March 2023, and no reports of fatalities or injuries related to this issue.
