2010 Harley-Davidson FlhtcElectrical systemEngine & coolingFuel system

I was traveling 55 mph in 5th gear when my motorcycle suddenly stopped accelerating, and the check-engine light came on. The vehicle automatically went into limp-mode and would not travel any faster than 25 mph. I was near a service station, so I pulled over and stopped. I was able to return home traveling 25 mph, as frustrated cars followed close behind me. My harley dealership confirmed the problem was caused by faulty wiring that triggered the limp-mode sensor.

2008 Harley-Davidson FlhtcEngine & cooling

Compensator in primary went out with only 25,000 miles. Upon research, it is found that this is a known problem to harley, yet they haven't said anything. This is a major cost to the consumer and most importantly dangerous!!! If this goes out while you are riding down the highway, it locks the back wheel and primary engine! No telling how many deaths happened with this and it's goes without anything being said. There should be an immediate recall before more deaths occur. Thank god my mechanic found this while fixing another unrelated problem. Harley should recall and fix asap without cost to us consumers! Bryan, tx

This motorcycle, with no warning will go into "limp mode". Limp mode is when the ecm shuts the engine down to 1000 rpm and will not let it exceed this rpm. Twice this has happened while in heavy traffic and only by the grace of god was I not run over from behind. The bike register three check engine light codes, p1511, p2135 and u1097. All codes are associated with the throttle by wire system losing communication with the control module. Twice this problem has been addressed by two different hd dealers and both...

dealers replaced connectors in the wiring harness. Both dealers have stated that it is a common problem with 2009 models and that hd offers o pin upgrade kit to address this problem, but that the kit seldom cures the problem. It certainly did not fix mine. In my humble opinion hd needs to fix this problem, it is a serious safety issue. Thank you. *Tr

Tl*the contact owns a 2007 harley davidson flhtc motorcycle. The contact stated his exhaust pipe turned red after overheating. The over heating is caused by the exhaust pipe and cylinder head. The dealer is waiting for approval from the regional manager to make the repairs. The failure mileage was 2,800.

2008 Harley-Davidson FlhtcEngine & cooling

Tl*the contact owns a 2008 harley davidson flhtc. The contact stated that the vehicle idled irregularly. The failure was intermittent and occurred while riding at 60 mph.

The next time he would start the vehicle, the rpm's would occasionally increase to 2,000 rpm's or higher. The vehicle would not decelerate due to the throttle failure.

occasions and was informed that many consumers have complained about this issue; however, they did not know the remedy. The dealer never made an attempt to correct the failure. The current mileage was 2,950 and failure mileage was 1. Updated 07/29/08 *bf the motorcycle would change idle rpm's up to and exceeding 2000 rpm's. At this rpm, the motorcycle will not decelerate as expected on throttle roll off.

2007 Harley-Davidson FlhtcEngine & cooling

My 2007 flhtc harley davidson has been a lemon since I bought it in 2007. The bike always runs hot due to the fact there is no oil pressure at times. The cpk unit went out and leaked oil everywhere after one month. The front part of this unit, which was inside the motor, was damaged. The dealership said something had to have hit it. Instead of tearing down the motor to find out what hit it they just replaced it. Oil pressure constantly drops after riding for awhile. The dealership said that was normal. Now the bike...

has no oil pressure and is leaking oil from somewhere. It is back at the dealership being worked on again. I do not trust this bike to go anywhere far from home. Something is wrong with either the oil pump or the way oil is circulated. You have to look while riding to see if oil is leaking from somewhere. If the motor locks up from lack of oil the bike will be past dangerous. Oil pump alignment has been mentioned on web sites as the problem. Harley will not stand behind fixing this bike correctly. There needs to be a recall. *Tr

2007 Harley-Davidson FlhtcEngine & cooling

I am writing to you because I sent a complaint in the other day for someone and had several things wrong. This is a mistake that I am sorry for. I should have had the other person proof over what I was sending in. He has had eight harley's in his garage. The heat comes from the crossover under the seat. Also, in the component information, the only thing close to the problem description was what I checked. I understand if this should be deleted, the consumer, lane tucker will try to send it in himself. *Tr

2007 Harley-Davidson FlhtcEngine & cooling

Purchased a 2007 ultra classic electra glide harley davidson on july 27. I had to return the bike this week and get my money back. This model has a heat problem which harley davidson and the dealers are aware of, they are selling these and not letting the consumer know about it. Once you are aware of this, they don't know how to solve it but they will change some things at your expense. I paid alot of money for this, not intending to go home and have to change it right away. The pipe under the seat gets so...

hot that it glows bright red. It burnt the passengers leg. After I complained enough, they agreed to take it back and return my money. They say that the 2008 models have the same problem. Why let them sell these? It's a shame because I have eight other harley's in my garage. The dealers are saying that the epa won't let them fix this problem and if the consumer fixes it, he is facing a $10,000 fine. What's wrong with this picture? *Tr

2007 Harley-Davidson FlhtcEngine & coolingTransmission & drivetrain

Motor runs hot; found by using 89 grade, runs cooler and better. Also dealer uploaded new ignition program - harley issued a fix. Getting it done under warrenty. *Jb gearbox noise: harley uses motor oil 20-50. Change it to full synthetic gear oil 85-120 (or something near). This quietens gear whine and makes it shift better. As a mechanical professor and on my 16th harley; never use 20-50 motor oil in any gearbox! Thats wrong in so many levels.

2007 Harley-Davidson FlhtcEngine & cooling

Engine creates excessive heat making the motorcycle almost unbearable to ride. If sitting in traffic long the heat almost burns the undersides of both thighs. Neutral light comes on when changing gears, it is very distracting at night causing rider to take his eyes off the road. Dealer said all of this is normal. Engine heat problem can be fixed but it will be at the expense of the owner. Neutral light coming on is normal dealer said.

Dt: the engine in the motorcycle was making noises. The consumer spoke with dealer on this matter and they said there was a need for repair but it would be at the consumers expense. This was a regular maintenance item but the factory will not acknowledge. The cam chain tensioners were wearing too soon. Consumer made repairs out of pocket. No problems since the repair. *Jb camshaft drive/bearing were replaced. *Tt
