i went though a buy back with an auto. with multiple problems. a friend of my brother-in-law who is a dealer told me to go in a demand the full purchase price of the vehicle back. he said to stand my ground they had to give it to me. well let me tell you, once i did this the game changed for the better. had a check in my hands 30 days later for the full purchase price minus seven cents a mile. the car only had 7000 miles on it, so it wasn't to bad. the dealer and GM gave me the run around for quite some time before all this took place. as long as the vehicle is under warrenty you have a case. sure was glad to get rid of that piece of crap car. moral of the story is you can do it, it's no fun but can be done. stay on them.

Problems with them can cause the PCM to add or take away too much fuel based on the faulty o2 sensor voltage.A P0152 code refers to the Bank 2, sensor 1, o2 sensor.... The O2 sensor varies the supplied reference voltage based on oxygen content in the exhaust.

Well it happened to me.... I thought I was going to have one that was trouble free. This weekend I rode it about 450 miles having a blast. I have about 1100 miles total and was ready to do my oil change this week.
I pulled into a station to take a bathroom break and a car didn't see me and was backing out so I honked the horn - it sounded like a wounded duck!!
Yes I know the M8 has Horn problems too! I plan to take it in for warranty replacement. I have relocated my floorboards and the Tour Pak, hope they don't deny my warranty
Hope I don't jinks myself..... Loving this thing!

My customer called me today and said that the dealer replaced the cam in his bike at 162 miles on it but they did not want to give him any paper work on the repair. When they did finally give him the paper work it had 2 qts of formula on it then he told me that when the bike started acting up at only 162 miles it would make a grinding noise and he could pull the clutch lever in and it would go away but also that when it would make the noise the idle would go up to 1100rpm. He is not happy about this and they told him that the build date was in june and HD said there was a bad batch of cams back then and all they did was change the cam out. He is going back there to pick up his plate today and is going to ask more questions about what they actually did to his bike he feels like they are lying to him because of the formula on the paperwork. Has anyone else heard about a bad batch of cams for the M8?

My thoughts exactly the dealer in question does not have a good track record to begin with.
