    The parking sensors on the CR-V have been working fine up until recently. When in reverse gear, i keep getting false warnings when there's nothing behind. I've cleaned around the sensors and sprayed wd40 on to them which seems to work for a short while. Any Ideas what else I can do. This only seems to be a problem in damp or wet conditions.

    Hi Steve,

    Water has entered into the reversing sensors in the rear bumper.I had this on my Tourer and its simple case of ensuring the wire clamp is removed and sprayed with contact cleaner and dried and then reinserted.

    if that does help it to the dealer for a replacement under warranty. After all they are German Bosch sensors on a Japanese car.. :Whistle:

    Thanks for reply Number one :Thumbup:. Can I presume that the wire clamp is accessible behind the bumper on the outside of the CR-V? I ask this to prevent me getting cold and mucky searching for it if it can be accessed inside the boot?
    Thanks again.

    Hi I'm also having problems with parking sensors but on the front corners, I have noticed that the inside circle has become bumpy and uneven. They give false alarms when driving and nearly always beep 5 times when stopping, I'm going to take them out and investigate more when time allows. Thinking I'm going to need replacements. Unfortunately until a couple of months ago the CR-V worked in a rough and dirty enviroment.

    Both the front corners and centre rear sensors corrode under the paint. Unfortunately sanding and painting is not an option. If you get false warnings that sensor requires replacing.

    Guess what these German sensors have failed on my car.. in the front will be putting a warranty claim at the second service.

    The CR-V gets its first MOT from me tomorrow, I've asked them to check out my sensor problem with their diagnostic equipment. Guess what, I'm being charged £49 for the privilege of using it!
    I will report back the results.

    Incredibly the CR-V FAILED its MOT because of emissions being out of limit!! " What"? with just 37K on the clock?
    We will put a petrol additive in and give it a quick blast up the motorway sir...I'll call you back.
    1 hour later i receive a call...all's fine with the emissions now but we will have to charge an extra half hours labour for the extra trouble we went to. You really need to do a few more longer journeys mate.
    Ok I said, how did you get on with the parking sensors? Umm, we couldn't get our diagnostic equipment to read them sir. Would you still like us to investigate them? We are probably looking at 2 hours minimum for dismantling etc and any parts needed on top. But don't worry we won't charge you for the use of the diagnostic equipment :Smile:.

    I politely declined.......

    I will wait for the warmer weather to come and have a go my self I think.

    It's a common practice to stick high octane premium fuel in from Shell/BP and give her a true rodgering right before the MOT to ensure the engine is hot and emissions are at their lowest. You don't often hear of petrol Honda's failing emissions unless they're true stop/start town cars that never get opened up. I'd assume she was just put through the MOT from a cold start.

    As for the sensors, an independent garage won't be able to read the codes on a basic ODB2 reader, that's something HDS would need to pick-up (if there is indeed a DTC being thrown up). You can attempt @Ichiban's suggestions yourself, and we can try and guide you through, or the alternative is to take the car into a Honda garage.

    Steve all you have to do before every MOT is to get the engine extremely hot after an Italian tune. It will pass everytime. The sensor TBH will be duff they only way to get that working will be a new one. Blame Bosch for making them out candy floss.

    My fault entirely, the garage was about a mile away from me and I drove it straight there on + 1 degree morning.
    I'm just beginning to realise that German auto products are not high on the list of quality from the contributors on this forum :Grin:

    was it a honda dealer you went to? i could have told you what was going on with your sensors in seconds and a good honda dealer would not charge such money. i take it your sensors are factory fit?. its very common for them to corrode under the paint and will require replacing. regards failing on emmisions, sounds like smoke and mirrors to me.

    I used a local garage for the MOT not a stealership.
    What put me off going to a stealer was the fact that they would not say whether the sensors would be covered under warranty unless they examined the car first. I asked for a scenario of what would qualify and what wouldn't; they would not commit themselves. Through experience, once they have the car in their possession, it's a case of listen to all the bulls**t and pay an extortionate price.
    Cynical? Moi!

    While sure main dealers are more pricey in general, they also do the job right with high quality genuine products. I just paid £35 for an MOT through Honda, which is their normal price when done with a service, £45 otherwise, I don't think that price can really be faulted.

    As for the sensors, that's a pretty standard stance for any warranty claim, it needs to be examined first so they can make sure someone hasn't gone and damaged them and is just trying to get a free repair out of it. Whether you're returning an item on eBay, or going to a manufacturer directly - the item is almost always has to be examined prior to approving a warranty replacement.

    I completely agree with the cynicism in general, and yes they are pricey on labour and the rest. Though there's certain jobs I wouldn't entrust to anyone else, and their stance on warranties tends to be pretty damn good.

    To me:
    • The Honda Brand is quality, reliability and value for money.
    • Japanese culture values respect and detail.
    • Complaints to HUK, about dealerships would be investigated and dealt with very firmly.
    • Tarnishing the Brand is something they would not tolerate.
    • Quality does not come cheaply, but compared to other brands, Honda are good value.
    Whilst most of the public are honest and decent, there are those that aren't.
    All retailers/sellers with any sense would want to inspect a 'faulty' item, to ensure misuse / abuse are not the cause of the failure.
    I have read on this and other sites, examples of where Honda have, once the 'fault' is verified, made all amends.

    That is not to say that things cannot go wrong.
    However, I believe many of the problems are due to incorrect/late servicing using non-OEM parts by previous owners.

    My feelings about the other Brands I have had dealings with over the years cannot be entered onto an open forum.

    I have owned and driven Hondas for a long time.
    As long as they stay true to these principals, I have no wish to change.

    steve4536 i take it your car is outside hondas warrantie anyway. If you have an extended warantie however it may have been worth trying to have them replaced under that. however as with every manufacturer not everything can be replaced foc but i am sure everyone would love that to be the case. naturaly it irritates me this '' stealers '' tag as i am a honda technition.

    beefy, the term stealership is not an attack on the employee's such as your self, I take my hat off to your specialist knowledge. I use the term stealership in a broad sense, covering all brands, (bikes and cars). It's the people in these organisations who set the charging rates and sales strategies that put most ordinary folk off from using them.
    I indeed do have an extended warranty and tried to gain information as in a previous post whether the fault would be covered or not and gave them the opportunity to say under what circumstance would it not be covered..(not difficult in my opinion).
    A short story regarding the rubber gasket under the rear light cover. I noticed that it was hanging down. A quick spot of sealant would probably have done the job but as the car was in warranty, i would give the stealer a chance. " a common fault with this model sir, I can't see why we can't do it under warranty". I dropped the car off with the promise of having it done that day.
    I receive a phone call about 2 hours later..." sorry sir it's not covered under warranty after all, it's going to cost you £120 to fix, we need to order the complete kit for it"....(we are taking about a rubber gasket which probably can be made for 50p)....bearing in mind the rear door has had some dismantling done to it, could I really expect them to put it back together and not charge me? After a lot of argy bargy I managed to get it down a fair bit lower than what they were asking.
    The only time a stealer appears to look after you properly is if you buy the car / bike new from them and it's still under original manufacturers warranty...so; no intended slur on you beefy, and I apologise if it appeared to be so.

    Obviously a dealership, like an independent, can be good or bad depending on which one as just take my experience for example, sometimes they are brilliant but then sometimes they let themselves down. But I think when it comes to dealerships as opposed to independents you should be able to expect consistent quality especially because of the higher rates and their accreditation to the brand. So when they do let themselves down they are punished harder by the customer's view. Perhaps a little unfair? I don't know but I would expect consistent quality.

    Got my 4th CR-V in December a 2007 2.2 diesel for towing a 1500kg caravan. Previous 3 models were petrol driven.
    I am obviously struck by the brand and model. Just done 1500 mile trip around the north west area of ROI and the CR-V returned an MPG of 49.8.
    Whoopee. Cannot find fault with that especially as for some of the time the vehicle was carrying heavy loads.
