Owner reports
Selected complaints filed with NHTSA by 1999 Honda Accord owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 1999 Honda Accord. The contact stated while driving at approximately 40 MPH, the steering wheel was vibrating abnormally. The contact stated no warning light was illuminated. The contact had the alignment checked by an independent mechanic who determined that the passenger's side subframe was extremely rusted, causing the vehicle to be out of alignment. The mechanic also advised the contact that the A/C drain tube had drained over the subframe on the passenger side and might have been a contributing factor to the extreme rusting of the subframe. The vehicle had not been repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 80,000.
My 1999 Honda Accord v6 has a rusted subframe on the passenger side. This appears to be caused by dripping water from the air conditioner. The drivers side subframe is in perfect condition. A simple internet search uncovers several news stories and official inquiries to Honda for an identical problem. Further no dealer or mechanics until a few days ago reported the problem to me. After seeing the extensive rust missing sections it's impossible to not see the damage when changing the oil. Even I can tell there is a problem. My car is now inoperable because it's not safe. At the moment it only has 110K miles or approx 6K a year. I don't see a recall for this yet the issue seems common.
Driving down the road and heard a loud clunk coming from the front end of the car. After this noise, the car did not drive or steer properly. Upon inspection, discovered the sub-frame on the passenger side was completely rusted through. This sub-frame provides mounting points for major suspension components. Upon further inspection, the drivers side was not rusted at all. Even further, it was discovered that the air conditioner drain hose on the passengers side drains directly on to the sub-frame below where the excessive rust caused the sub frame to deteriorate.
Began hearing unusual noise from right front tire area when turning. Upon investigating, discovered that the right front tire was worn excessively and that the right front sub-frame is rotted out. No other part of the frame is rotted only the right front. Apparent cause is a design flaw where the A/C drain tube is located directly over this sub-frame and causes it to prematurely rust and rot out. I cannot get an alignment because the sub-frame is too weak. I cannot drive the car because the sub-frame will likely fail causing loss of control of the vehicle.
The issue is not really "suspension", but sub-frame. It is a part called the rear beam and it supports the rear engine mount. Part number 50200-s84-a00 has rusted entirely through. As numerous people have reported online, it is true that an A/C drain hose drips right onto this piece of sub-frame and completely rusted it through until it broke on the passenger side. The other areas of this part and the attached front beam are in fine condition and the repair looks to be about $2000. I have some pictures if needed.
My daughter was home from school and complained of s clunking sounds when turning from the right front. I removed the wheel and found the subframe was rusted out on the rear on both sections. I did some research and found this to be a common problem on these 1998 to 2002 Honda accords. The left side was fine. This seems to be due the air conditioning condensate dripping on the frame area. Luckily this was found in time before an accident or worse could have occurred.
I have a 1999 Honda Accord and I jus paid to get front headlight wire replaced because I could not use low beam lights only high beam. Light is working now but there is a suspension and/or electrical problem I need to check. The heat/air doesnot come on? Is this car safe to drive?
1999 Accord 4 dr 3.0 with major rust in front right sub-frame under the ac drip hose. Major failure to that part is anytime now. The other side in same area is rust free. Car is 98% rust free. Garaged, 118K currently. Googling this issue pops up many complaints of this defect!
The front subframe is rusted through on one side only. It's the passenger side where the ac drain hose dips on the frame. The car is in otherwise good shape and doesn't present any real issues but the rust is so bad that it is making the car very unsafe.
I was alerted to a potential problem with the subframe of my vehicle that has caused me to park it. The problem is that the rear subframe has rusted to the point that it is broken in three places. The rear subframe is located in the rear part of the engine compartment and supports the engine and front suspension. I was driving this car for an unknown length of time in this condition. I was informed that this is a safety concern and that the car should not be driven. The portion of the subframe that attaches to the sway bar is completely broken loose from the frame. The location of the rust is under the outlet of the air conditioning condensate drain. This is the only location where the sub frame is rusted. The distilled water coming out of the air conditioner is corrosive to metals. …
