Honda Accord water leak problems

Filed Sep 28, 2026 · Body · MD

On August 29, 2026, I took my 2025 Honda Accord to Norris Honda for a persistent rotten-egg/sulfur-type odor. I paid $407.67 for a filter replacement and odor treatment, but the odor persisted. I returned the vehicle on September 9, 2026, at 5,640 miles. The odor was particularly noticeable while driving with the air conditioning operating. My adult daughter independently noticed the odor. There were no warning lamps or dashboard messages. On September 15, a Norris Honda technician reported detecting a different “moldy odor” when opening the vehicle before it was started. Norris Honda subsequently reported that the right sunroof drain was clogged and had overflowed, allowing water into the passenger compartment. The dealer stated that the carpet requires replacement and later reported mold in a “pan.” The vehicle and affected components remain at Norris Honda and are available for inspection. I am concerned about safety because water entered the passenger compartment and the full extent of moisture exposure has not yet been established. As of September 28, I was told the affected/moldy carpet was still in the vehicle and had NOT been removed to inspect underneath it. Therefore, whether water or moisture reached wiring, electrical connectors/modules, insulation, seat-related components, or other systems is UNKNOWN. The water intrusion and affected carpet have been confirmed by Norris Honda. However, the exact cause of the drain obstruction, why it occurred, the duration and full extent of the water intrusion, and whether the original sulfur odor is related to the subsequently identified water intrusion/mold condition remain UNKNOWN. The vehicle has remained continuously at Norris Honda since September 9. To my knowledge, it has not yet been inspected by an American Honda manufacturer representative, police, insurance representative, or independent service center. I have requested photographs and a complete inspection beneath the carpet before affected materials are r

Since I purchased vehicle in 2008 the rubber seals around the front and rear windows leaked water at the car wash 3 days after purchase. They repaired/resealed! Less than a year later the rubber seals at bottom of driver door window started leaking water into the inside of door. Car was parked in garage, rubber not dried out or loose. Eventually all four doors started leaking and rubber started peeling up and flapping, flying off when driving! Dealership stated not a warranty issue or recall item when reported in first 3 months. Noticed online other drivers/owners of same vehicle complaining of identical problem. Vendors want approx.$500 to replace rubber window seals on all 4 doors! Its 2026 and front windshield 'rains' inside driver side at car wash and days it rains. Believe car was lemon when purchased. Dealership in Henet Ca, only sold to people with bankruptcies and bad credit!! Also, front driver seat adjusted bottom seat to raise or lower. Stopped working after first year, only weighed 140lbs. Shouldn't have been a weight issue. Also told not warranty or recall. Key fobs NEVER worked, replaced first one till I was told that year car had battery issues in FOB and no longer covered. Would cost 100-150 for new batteries or FOB. After market batteries never worked so just use key to open door.

ssue: Water intrusion into tail light assembly causing electrical and safety system malfunctions Status: Repaired at owner expense (~$800) Concern: Safety‑related defect and potential pattern across vehicles Description of the Issue: My 2021 Honda Accord experienced a failure where water entered the tail light assembly and caused electrical shorts. This resulted in multiple safety‑critical system warnings, including brake system alerts, ABS/VSA warnings, and Honda Sensing failures. The vehicle also lost acceleration and entered a reduced‑power “limp mode,” creating a hazardous driving situation. The dealership diagnosed the issue as water intrusion into the tail light assembly. The entire assembly had to be replaced at a cost of over $800. After replacement, all warnings and drivability issues resolved immediately.

Back windshield leaked. A third of the seal was not installed and water leaked into roof liner in car. Leaked from rain and car wash. Suspension clunks and makes noise like an old car. Vehicle in shop almost 30 days 1st year, at least 18 consecutive. Dealer recommended vehicle be bought back due to issues but honda regional mechanic came in and said tha'ts just how they ride. Car still rides like an old truck over bumps. No satisfaction as far as I'm concerned.

Both front driver and passenger side air bag curtains that connect to the roof are leaking water into the vehicle when it rains. I'm aforesaid this could affect my airbag in the event of an accident. I never realized this is why my driver seats are wet when it rains.

I paid $1300 to replace a timing belt and a leaking water pump. The mechanic test drove it when the repairs were finished, only to discover a loud squeaking which revealed a rusted right front subframe that I have found, after some online research is fairly common and due to the placement of a drain tube that leaked water over this spot on the subframe for 20 years.
