Just thought I would update in case anyone can offer any further advice.
After my last post things are no better I have now had 4 locks replaced, first the front driver and passenger, then the driver rear door which had been playing up failed when it went for its Mot in March so that was diagnosed with the same problems and fixed under warranty. Not long after the the front passenger lock, which had already been replaced last year, went yet again and the garage fixed even though it was out of warranty by a month or 2.
By this time it was getting beyond a joke and even the garage who had been replacing them agreed so I reported it to Honda UK. To be honest I was not impressed with how it was dealt with them and felt they just fobbed me off, saying that they would be surprised if it happened again, I said I would be more suprised if it didnt. They said if it did happen again to go into my local garage and they would 'consider replacing' even though it was out of warranty, they would not say they would definitely replace even though it is clear there is an underlying problem which started well within warranty. I asked was there nothing else that could be causing the door locks all to break and they insist there is nothing else. This complaint was in April or May, cant remember the exact date and I asked them to put in writing what was said to me so that if it didnt happen again I would have a record of my complaint. They said I didnt need it in writing as it was on their records but they would send it to me. I also told them I was not happy with how my complaint had been dealt with as I felt they had just fobbed me off and not resolved the problem. As yet I am still waiting for the letter.
Last week yet another door lock went, this time the back passenger, the only door that had not failed. This could have been faulty for weeks as it had been at least a month since the door was last used and how many people check doors not in use. I rang the garage to inform them and they have contacted Honda and I am still waiting to see if they will fix as the warranty ran out in March. When I spoke to the garage they had no record on their system of my complaint to Honda UK, so much for Honda UK and saying it would all be on their records. I now have a door that has been locked every time I have checked for over a week.
This is the first Honda I have owned and I cant fault the garage they have done all they can within warranty rules to help me out, but I am not happy at the amount of time my car has spent in the garage and with Honda UK and the way they have dealt with my complaint.
Re the response to my original post, thanks for posting, I find it hard to believe they are all from the same batch as my car was made in 2009, was fine for the first 2 years and the replacements have been done over a year's period and I have just been unlucky enough to have 5 of them. I am sure there would have been further reports of others having the same fault if that were a batch of them. I was wondering if maybe something else may be causing the actuators to go faulty, ie an underlying problem not yet discovered, as it does seem strange for so many door locks to go in just over a year.
