 Tl*the contact owns a 2002 honda gl1800 motorcycle. while traveling 14 mph, the motorcycle would overheat and shut off. the dealer stated that the ecm was failing. the estimated repair cost was $1,000. the vehicle has not been repaired. the contact called the manufacturer and was informed that no compensation would be provided because the motorcycle was not under recall. the failure mileage was 19,000 and current mileage was 21,000.

 My motorcycle was subject to the june 2003 engine cooling campaign which included replacement of the ecm and other adjustments. i had my bike repaired on july 30, 2003 at honda of milpitas (r/o 94030949). since the campaign repairs were done, the bike has had a surging problem at 1500 rpm. when riding, or if the bike is stationary, when i open the throttle to 1500 rpm, the engine speed drops to 1000 rpm and then jumps back to 1500 rpm. this will go on for as long as i hold the throttle at 1500 rpm. while this is not a problem when the bike is stationary, it is a big problem when riding. when riding in parking lots, in traffic or when making low speed turns, i frequently run the engine around 1500 rpm and when i hit that rpm, the engine speed drops without warning. on several occasions i have almost dropped the bike in a sharp turn when the engine speed dropped. since i cannot safely watch the tachometer and the road at the same time, it's very hard to drive around that engine speed. not only is this behavior annoying while riding, it's also dangerous as i could be injured if the bike fell when the engine speed dropped. i took the bike back to honda of milpitas in june 2004 to have them look at the problem. both the service manager and the technician confirmed the problem but said it was an ecm mapping problem and that american honda would not authorize them any time to troubleshoot and repair the problem (r/o 94034826). *tr

 Temperature gauge has a tendency to go into the red while being driven. the owner was instructed by honda motor company to pull off the road and check the anti-freeze, fans are running, etc., the problem also exsisted with the 2001 models but was modified. honda motor company is telling him that they can not do anything at this time. nlm

 I have ridden the motorcycle four times in traffic and each time the temperature gauge indicated a reading that according to the manual was unsafe to the operation of the engine. upon contacting the manufacturer they claimed that the temperature gauge was innaccurate and that overheating actually occurred only when coolant was dispersed from the cooling tank, contrary to what is stated in the manual. the motorcycle operates entirely different when running in the red zone, it is hard to shift and extremely hot. i cannot believe that riding at these constant elevated temperatures is safe for the engine or the rider. additionally, independant testing of the coolant temperature confirms the degree at which the engine is operating at potential prolonged periods is indeed excessive and damaging. this causes one to have to find any shoulder, grass area or curb to pull over everytime one is stuck in traffic which is a normal occurance in everyday riding. there is no reason that this problem should occur on a regular basis in traffic where any other vehicle fairs just fine.

 While riding brand new motorcycle in traffic my temperature guage redlined. i was able to pull off the road fairly quickly where i waited 30 minutes for temp to come down. i then proceeded when motorcycler cooled enough. i have been unable to contact dealer at this time because they are closed sundays and mondays. i am a member of a large goldwing club and have read about others having the same problem. honda's reply is that the bike is not overheating it is just a perception that it is. ths was no perception ... the guage pegged out over the redline and there was much heat coming from the engine area. the gl1800 has an al block and i am concerned that damage may be done by the perceived overheating. honda will not do anything to fix the situation as i have seen many others with same problem and the answers they receive from honda. hopefully the nhtsa will be able to force honda to fix this very real problem. the vent tube is directly in front of rear tire! if the bike starts to spew coolant in front of tire this will be a very scary, slippery ride! help. *ak

 Engine overheating - i purchased the bike in july of 2002. i experienced overheating almost immediately. i took it to an authorized dealer in temecula california and had it checked out. they kept it for approximately one week and determined that there was no problem. i then contacted the honda cooperation and was told to take it back in. i did. again nothing. i am not overseas and have been here since oct 2002. i haven't ridden the bike and won't ride again as i am in the marine corps stationed abroad until 2005. i finally discovered this site and realized that there are many, many others having the self-same problems as i am having. i haven't ridden it enough to determine if there is anything else wrong with it as others have. i have not received any recall notices or anything. honda has my address stateside and overseas as i do receive my bill here. what is being done to remedy these matters/concerns of us who have paid in excess of $15,000.00? when one spends his/her hard earned money on toys, we expect much better than this. *la

 When stuck in slow moving traffic going into the city the coolant temp gauge went deep into the red. with nowhere safe to pull off the road i was forced to proceed with the fear of the engine boiling over. after looking online at the gl1800 web sites it appears that this is caused by faulty manufacturing. honda designed the radiator fans to blow the air foward up to a speed of 15 mph. any faster than that they are designed to shut off and allow the ambient air to push through the radiators in the normal direction. apparently this was done to try to keep some heat off of the rider at low speeds. however, when you are in travelling 10mph in warm conditions the 10mph incoming air is fighting against the air from the fans. this causes little or no air going across the radiator fins, thus causing the overheating condition. if the bike is stopped on the shoulder, the fans will push the air foward and allow the bike to slowly cool down. there is not always a shoulder to pull onto, and if the bike overheats the coolant overflow from the radiators is aimed directly in front of the rear wheel. a situation that can certainly cause loss of control and possible serious injury or death. the fans need to be mounted on the other side of the radiators so they can pull the air through. in the direction that nature intended. will it take someone getting killed for them to remedy this. i certainly hope not, but so far they are in denial that this is a problem. i feel that this vehicle is unsafe to ride. i am not willing to risk me and my wifes life. this vehicle was bought with pleasure in mind. if nothing is done to alleviate this i will have honda buy the bike back from me with new jerseys tough lemon law.

 The cooling system has overheated to the danger zone 3 times while riding a slow speeds. i owned the previous model ( a gl 1500 gold wing) and it never overheated under the same circumstances. in fact on 2 of the overheating events i was riding in the company of 2 of the older 1500's who had no trouble at all. my concern, and it should be yours as well, is the overheated cooling system dumping coolant on the road in front of my rear wheel. that could lead to serious injury. it appears that the factory has changed the airflow direction at low speeds in this model.*ak

 Brand new motorcycle overheated (gauge deep in the red) on our first trip. it has since overheated sixteen more times. honda says to ignore the guage but will not fix the guage. i believe the guage is working because i can feel the excess heat generated on my legs. this problem occurs anytime you are driving between 15 and 30 mph. honda says to drive in 3rd gear. i tried this and it does not prevent the bike from overheating. i overheat anytime i get stuck in traffic or when i am cruising residential neighborhoods obeying the speed limit or simply enjoying a scenic drive. i often need to pull over in heavy traffic to let the bike cool down causing disruptions in the traffic flow which i feel are very unsafe. i feel like i have a lemon because honda refuses to fix the problem and i do not feel safe driving it. i would sincerely like to get my money back. i bought this bike thinking honda had an excellent reputation. they are trying to take the easy way (ignore the consumer's safety problems) out. please, can you prod them into responding to this issue? thank you. stephen g. lockhart p.s. i have ridden motorcycles for 33 years. i am riding this motorcycle according to the manual's reccomendations. honda wants me to ignore the manual!*ak

 This motorcycle continues to over heat under specific conditions which honda corp refuses to address and primarily blames the operator for improper use.honda states that unless the motorcycle coolant overflows there's no problem and that the motorcycle was not designed to be ridden at less than 30mph.aluminum heads on the motor will not take constant 260deg heat without eventually failing.this should not be happening on an 18k+$ bike and hondas response has been horrible.he motorcycle will. *ak

 My concern with this 1 month old motorcycle is that it easily runs to the top of the temperature guage when operated at around 10-15 mph regardless of ambient temperature. it also should be stated how this defect relates to the issue of safety: for example, having to monitor the engine temperature gauge while driving could be hazardous ...this is proven with cell phone use while driving--very distracting and even more so if you are concerned that the engine may get too hot and seize, causing death or injury. i called honda motor corporation; who has acknowledged this condition, but i was advised that they do not have a fix for this condition.*ak

 This is a motorcycle related problem. there are a number of owners of 2001-2002 goldwings that are experiencing overheating problems. this is a potentially serious problem. spewed coolant could cause loss of control. a seized engine on the expressway could spell disaster. there is a design flaw with this m/c. the cooling fans blow forward at speeds around 10 or 15 miles per hour. if these speeds are sustained (traffic problems related to dot or accident), the bike overheats because the incoming air is cancelled out by the forward blowing fans causing stagnant air around around the radiators. honda basically refuses to acknowledge a design flaw and blames it on the gauge. the nhtsa needs to go beyond honda's stonewalling and check this situation out before someone riding this m/c is hurt as a result of the overheating engine and cooling system. thanks. *ak

 This new generation honda goldwing motorcyle released for model year 2001 has a cooling design defect that causes the engine to dangerously overheat when caught in stop and go traffic conditions. yesterday, (june 30, 2002) myself and two others also having 2002 goldwings were returning from a trip and found ourselves in a major traffic backup in a road construction area on us interstate 35 south of minneapolis, minnesota. all 3 goldwings overheated in the stop and go, single lane conditions. there was nowhere for any of us to safely pull over to shut the motorcycles off to cool. we were ultimately forced to drive on the narroe temporary right shoulder at high enough speeds to allow the rushing air to cool the engine enough to keep it from blowing up. this was extremely dangerous as those caught in the traffic backup thought we were trying to drive on the shoulder to ellude the congestion and people started pulling their vehicles out in front of us as we proceeded along the shoulder strip. this is a widespread condition with this specific model bike that honda is fully aware of yet refuses to do anything about. they won't even acknowledge that there is a problem. honda's customer service personnel have been instructed to tell everyone calling in about this issue to not worry about riding it with the temperature needle in the red zone unless it spews coolant...even though the coolant overflow tube discharges the coolant on the ground directly in front of the rear wheel, which is also a huge safety issue as the antifreeze can cause the rear tire to lose grip on the roadway. by officiallty advising us all to just keep riding with the temperature needle in the red zone, honda is directly contradicting the directive in the owners manual that states if the temperature needle enters the red to zone to immediately pull over and shut the vehicle off. continuing to drive will void the warranty. i hope you will help us all. it's hard to fight a big co without help!*

 Motorcycle consistently overheats when driving at 10-15 mph for 3-5 minutes. this appears to be caused by a cooling fan which blows air forward instead of backward. when the cooling fan forward air speed equals the ambient front-to-back airflow speed, there is a net zero airflow over the radiator which causes the motorcycle to overheat. this overheating could cause injury if the overheating causes coolant to escape through the vent tube which would expel coolant directly in front of the rear tire. *jb

 Cooling sys design activates fans below 20mph. around 20mph, it appears that the fans (blowing forward) and the ram air (blowing backward) create stagnant air at the radiator. the result is consistant overheating at or around 15-20mph. within one minute the temp guage goes from normal/middle to redline. majority of this models owners are report the same thing on websites such as: www.gl1800.org. *ak

 I recently purchased a new 2002 honda gl1800 motorcycle, and now have 4500 miles showing on the odometer. this motorcycle is experiencing the same overheating condition that has been well documented with the nhtsa. most recently, it overheated while stuck in traffic on the interstate with an ambient temperature of about 89 degrees. honda has recently begun a campaign to replace the engine control module and inspect/replace the heads and radiators. questions are being raised on many of the gl1800 web sites as to the effectiveness of replacing the ecm. there are some owners who have seen poor results from the ecm replacement and some have reported performance and gas mileage reductions with the new ecm. some owners state that this service campaign may just mask the effects of high temperature by recalibrating the temperature guage. as stated in previous complaints, this is a major safety hazard to have the motorcycle overheat in heavy traffic. please add this complaint to the gl1800 overheating population and continue to monitor honda's actions to ensure proper corrective actions are implemted to resolve the issue completely.*ak

 My 2002 honda gl1800 has been into the dealer 6 times for repair of engine overheating. i have had the engine overheating recall work conducted twice on the bike. the first repair under the recall actually actually acerbated the overheating problem. the second recall repair only slightly improved the bike over its original delivered state. american honda refuses to do any further repairs that could rectify the problem. it appears that some of the gl1800 motorcycles have this inherent defect and others do not. honda apparent refuses to acknowledge that some people have an overheating problem which is not rectified by their ecm recall. the overheating makes the vehicle undrivable in heavy, congested traffic at low speeds. honda says to pull over to the side of the road when it overheats. sitting on the shoulder of the l.a. freeway on a motorcycle adjacent to congested traffic and screaching auto and truck brakes is unnerving and quite unsafe. american honda's v.p of the motorcycle division, ray blank, has refused to respond to my two complaint letters appealing for honda to correct the overheating problem. the recall repair that honda is utilizing doesn't work and corret the defect for many gl1800 owners. i ask the nhtsa for assistance. *ak
