Clarity Issues

I have had problems with power loss. Most recent (and worse) loss of power in highway- car went down to 1 bar- engine revving got up to 43 mph and had to limp off highway, then pulled over and restarted car- still sluggish and revving but eventually got back to normal. Went to work and left at end of day and did same thing- could not get above 30 mph until I pulled over and restarted. Seems to at times loose power and drive sluggish and other times work fine. Taking to dealer today.
Ho Boo, please put a complaint with NHHTA and NTSB. Dealers have no clue, Honda denies everything. The more people complain about this issue the more chances we have to get the car recalled.
I brought my car a couple days ago (11 issues: high rev, HV and HV charge not working properly, engine turning on while on EV...) they had told me there was 3 updates, the service guy found 4 recalls in his system. I picked the car up, first 10 miles it was a complete different car, super silent while on HV charge (I asked twice to charge the battery, they still gave it back with dead battery). After that the issues came back along with new ones: engine turning on and off, extreme revving while on HV. This has been going on for 6 months, 3 dealers, 5 tries. Honda has no clue on how to fix the issue.
PLEASE post a complaint about the extreme rev and loss of speed with NHHTA and NTSB.
 
20 miles for a diagnostic test seems likevdue diligence to me. I think an independent mechanic is your best bet. You need an independent expert to verify that you either have a safety issue or that the car doesn't satisfy its use case for transportation.

I'm not sure what the arbitration process was, but if you didn't have evidence from an expert on your side, I'm not sure how your argument would be too convincing, especially if you are still driving the car.

Keep in mind that engine revving isn't a problem. Failing to start once isn't a big deal either as every ICE system does many diagnostic tests before turning on. If it happens so often that you can't use the car, that is different. Even limited power isn't a major safety issue if it happens very rarely and you still have control -- there are many potential failure points on any car starting with those balloons we call tires.

Are you able to share any videos or photos you have of the loss of power? I speculate that this could be a sensor issue -- the guys here might be able to provide some ideas on that.
 
When you are on the freeway at 70mph and your car suddenly goes on high revs like being stuck wide open in first gear and your speed goes down to 36mph I call it a problem.

Just curious...what is the build date of your Clarity? Asking for no reason except may be good to know build dates for anyone who has this problem to hopefully/maybe narrow it down? Common thread perhaps?

Have you gotten any response from the government watchdogs? This should get Honda USA attention.

What amazes me is the gall and the arrogance that both Honda USA and their crackerjack dealer network display when someone like you comes forth with obvious concerns and they act like you're a bother. Despicable really.

Like you stated in another thread...lets hope no one is seriously hurt or worse.

No Honda fan boi's need to jump down my throat...yes...I realize there are some good Honda dealers out there...plain fact is they are few and far between like any other auto manufacture. Sad part is, the customers who have to deal with these shady losers pay the price.

Good luck.

The car was built 12/2017, I know your car has the same issue with high rev, when was yours built? Maybe we have the same "bad batch".
No news from anyone...
After the 4 recalls the revving is back but not as extreme like 1st gear wide open (more like 5000 pm) but still very sudden and loss of speed! I also have another issue with the engine turning on while on EV and once it does that the only way to stop it is to turn the car off. Yesterday on my way home I had to do that 4 times!! I thought I was going to blow a gasket.
Brought the car to the dealer (6th time now) and of course it did not do it. I had sent videos and photos to the manager and asked him to call Honda to see if they could bring that specialist I had been promised and arbitrator required, Honda says until the dealership can duplicate it they will not send anybody. I told them to keep the car for a week and have the manager drive it everyday instead of his Clarity, he said he has to check with Honda again. What a joke. Honda sucks, dealerships make no effort and I am stuck with my POS car.
 
Yannick, any update on your issue.. I had this high rev power loss last week.. just go back from he dealership.. and found nothing.. I will ensure I do not run down the EV .. i'm pretty sure that is when it happened to me.. the EV battery went to 2 bars pretty much dealer response.. unless the engine light come on .. they can't find anything. if you have any more info.. let me know
Please put a complaint with NHHTA and NTSB, it is the only way we will get the car recalled!
 
My clarity has 7K miles.. I limped home after dealer #1 said there was not issue.. I got home on hi reving going top speed of 50.. plugged it in and for 20 miles EV charge and vola back to normal.. when battery drained again .. no issues either.. just got back from dealer I bought I from and they could find nothing.. i'm reading all 24 pages of info very informative.. found this site when waiting for the flatbed by the side of the road appreciate all the info. will not let my car go to 0 when on highway again
You should not have to do that! Please put a complaint with NHHTA and NTSB.
 
Hey folks, I am having the same issue. It is in the shop a second time for the high uncontrolled revving and loss of acceleration. Has happened three times at slower speeds, 25-35, battery depleted and a slight incline. One of those times on a flat straightaway. This fourth time, on the highway, cruising speed of 68mph, 6 bars on battery and in hv charge mode. Very scary and dangerous!
Lash, how is your car doing? Still have the high revs? Please put a complaint with NHHTA and NTSB it will help.
Looking forward to hearing from you.
 
This great info. The high rev low power happen to me on Christmas with 6 mile of EV range left. I was Going at highway speed in cold 14F. Mine is canadien car receive in June. I was in HV mode .
 
Another issue is fit and finish. My driver side pillar (between driver window and windshield) seems to be installed poorly, not properly aligned (has gaps) compared to the right pillar. Is this something I can easily fix? If so, any tips how to remove and realigning it successfully?

Check out the Dashboard Rattle thread. People removed the trim on the inside of the A-pillar to stop a rattle from the trim or the speaker mounted there.

Actually the dash is about 1/2 inch lower on the driver's side near the front. You can tell by comparing where the dash meets the windshield with the dash on the passenger side. It's a installation issue.

Several folks have had this issue but Honda USA refuses to recognize this as an issue. Several folks have said dealers don't do anything about it but one fellow was successful in having his dealer fix it while another owner fixed it himself.

Try Honda USA and see if they will help. It's an obvious defect but getting any American company to admit anything is next to impossible these days even with photographic evidence.

Keep us posted.

Good luck!

I think I will try them.
 
I’d like to add another data point to the mix since I seem to be an anomaly on this forum. I don’t have regular access to charging and drive my Clarity in HV mode with 2 bars the vast majority of the time. I have over 12 thousand miles on the car, which includes multiple 500+ mile trips, long hills (though not mountains), and many miles in below-freezing weather and snow. I’ve experienced unusually high revs maybe a dozen times, “angry bees” once or twice, but never loss of power.

For those of you that are experiencing power loss at or above 2 bars, that is definitely not expected behavior. The only case where I believe Honda expects a power drop would be if you’re climbing a literal mountain and your battery drops below 2 bars.

Has anyone seen a drop on their H70 fill-up range? I have a 2017 Honda Clarity FCV and love the vehicle. Use to even get 370 mile range on some fill-ups during the summer season. Now as winter has hit, I am lucky if I get 285 range on a complete fill-up. I recently had my A01 maintenance and the dealer was at loss as to what is going on. Next step will be to reach out to Honda America if I cannot get a resolution.

Many thanks in advance for the replies ...
 
That’s only a 23% reduction in range and would be consistent with colder temperatures and use of heater and defroster. Batteries are not as efficient at colder temps and the cabin heater uses a surprisingly large amount of power. We PHEV Clarity owners (especially those up north) have seen even worse reductions in EV range in winter. If it’s not a problem with the FC, then try reducing heater use by using the seat heater which robs much less power from the battery.
How much did the temp go down and how much are you using the heater?
