2018 Honda Odyssey body problems

Filed Oct 28, 2026 · Body · OH

The motor on the passenger side sliding door on our 2018 Honda Odyssey failed. The door could not be opened electrically - or Mechanically from inside or outside the vehicle. We had it repaired at the dealer at a cost of ~$2,000. The sliding door was INOPERABLE when the motor failed. If the car was in an accident the door could not be opened by second or third row passengers or first responders to enable evacuation from the vehicle. This is EXTREMELY DANGEROUS! The problem was confirmed by the dealer. The sliding door can’t be opened when the motor fails. The dealer also stated that Honda had an active engineering assessment in process and that a recall might happen - so hold on to our receipt.

In XXX, the power tailgate on my 2018 Honda Odyssey stopped working. I took the vehicle to authorized Honda dealer Fred Beans Honda of [XXX]. The technician documented in writing on repair order #XXX (XXX): "There is water leaking onto the power tailgate control unit. Technician found the water leak going into from the back of roof on the left side. Needs a new power tailgate control unit." Water entered through the rear body seam seals and dripped onto the power tailgate control module (P/N 74970-THR-A12). The removed module showed severe blue-green corrosion -- it does not fail on its own at 31,500 miles. Safety concern: A tailgate whose control module is destroyed by water intrusion cannot be relied on to latch or stay closed; an unlatched or unexpectedly opening tailgate while driving endangers occupants and surrounding traffic. Known defect, not isolated failure: Honda issued a TSB on rear body seam-seal water intrusion on 2018-2019 Odysseys; federal class action Case No.XXX (XXX.) covers 2018-2021 Odysseys with defective polyurethane seam seals destroying the power tailgate control module; numerous owner reports in the federal safety agency database describe identical failures. What I did: The dealer quoted $1,302.88. I first asked American Honda by phone for goodwill coverage and was denied. I repaired it myself with a genuine Honda module ($215.57, Order #XXX, XXX); total out-of-pocket $416.92. On XXX I submitted a written goodwill reimbursement request online (case #XXX, continuing prior case #XXX); on XXX Honda denied it as not covered under any campaign, even though the failure is caused by the documented seam-seal defect that is the subject of the pending class action above. What I am asking the federal safety agency: record this complaint and consider investigation/recall of the 2018-2019 Odyssey seam-seal water intrusion defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owned a 2018 Honda Odyssey. The contact stated that water was seeping into the trunk during inclement weather or while washing the vehicle. The contact stated that several warning lights remained illuminated, and the cruise control, blind spot detection, lane departure warning, and powered tailgate failed to function as intended. The vehicle was taken to a dealer where it was diagnosed, and the contact was informed that the metal on the power tailgate needed to be welded to stop the leak, and the dash camera and computer needed to be replaced due to the water damage. The vehicle was repaired; however, water was still entering the vehicle during inclement weather or while washing the vehicle. The manufacturer was notified of the failure. The failure mileage was 88,000.

The vehicle doors have given issues where they open when attempting to close. The doors will start closing and then reopen or don’t close at all. We’ve had this van for about a year and started having this issue early on. Upon searching online, it was discovered that are many instances where door issues have occurred and a site found to further support this but my VIN was not listed even though the same issue occurs. https://www.consumerreports.org/car-recalls-defects/honda-odyssey-minivan-recalled-over-problem-with-sliding-doors/#:~:text=Honda%20is%20recalling%20107%2C000%20of%20its%202018%20and%202019%20Odyssey%20minivans%20because%20its%20power%20sliding%20doors%20may%20not%20latch%20properly%2C%20raising%20the%20possibility%20that%20they%20could%20open%20while%20the%20vehicle%20is%20in%20motion%2C%20according%20to%20the%20National%20Highway%20Traffic%20Safety%20Administration.%20According%20to%20Honda%2C%20some%20components%20in%20the%20power%20sliding%20door%27s%20rear%20latch%20assembly%20are%20prone%20to%20sticking%2C%20which%20can%20stop%20the%20front%20and%20rear%20latches%20from%20securely%20connecting.%20This%20problem%20affects%20the%20left%20and%20right%20power%20sliding%20doors%2C%20Honda%20says.

Creaking from drivers side footwell. Pinch weld has to be oiled and greased. Vehicle has 108k miles. Front suspension entirely replaced, and the noise boiled down to the floor flexing and metal pinch welds moving and creaking. This is a common issue apparently in the Honda community.we now have to spray the pinch welds every week keep the noise down. Poor build quality.

Water is leaking through back tailgate every time it rains. Water pools on the back floor and gets into the tailgate control unit. As a result, mold has grown on the floors and water has gotten into the power tailgate control unit causing my tailgate to stop opening and propping up (I have to manually hold the heavy door while lifting items out). This has caused electrical problems with cruise control and several lights blinking on and off my dashboard throughout the duration while driving. I have had the engine and transmission all tested and everything is working properly in that regard. The conclusion is that these electrical malfunctions are due to water damage. I have already had the control unit replaced once a year ago.
