Today I received a recall notice for my TLX, sh-awd, advance. It says the issue is that "the vehicle may shift into Neutral and the transmission indicator comes on. The driver will not be able to select any other gear until the vehicle is turned off and restarted."


The fix - "the dealer will update the software in your vehicle. The update takes about 30 minutes".


I have been reading the thread about the 1-2 and 2-3 shifting issues. It seems that some owners who have had software updates done to their cars have had their cars come out worse than before the update was applied.


Has anyone had this update done to their car? If so any changes to the transmission shifting?


FYI - it also says that for California owners "The DMV will not renew your registration until this product update has been completed". I am glad I do NOT live in California. I can ignore this update if I wish.

 

What's your VIN number or range?

 

vin number ends in 005004

 

I found that this is TSB 15-034

 

Wow, what a piece of shit. Sorry... but a recall on the transmission on a brand new generation... 5th generate to be exact.

 

Is this an official recall? savecar.gov does not list it. I have a SH-AWD and have not yet received such a recall. But maybe not in the VIN range. Anyway, California did let me renew my registration!

 

It's not an official recall (as of yet). It's a TSB. It's VIN-specific.

I think you are correct about it not being a recall. It is an update that Acura wants to do to my car. The big question is has anyone had this done and what were the results?

 

Ha! Took my car in Monday morning for A1 service (no charge since it's my first service). Mentioned some of the TSB to the service guy and he didn't sound too happy I was telling him about which TSB to check and perform. To my knowledge, TSB should always be checked/performed on cars when you take it in. Why do I have to initiate the work order?
Anyway, I saw this particular one and told him it was newly listed and if he can check it out for me. His response "if your indicator lights don't come on then you don't need it". Came home with the loaner 2.4L tlx to find the recall letter in my mailbox! Going to call in the morning and make sure they get this TSB / recall done while my tlx is in the shop!

 

Anyone notice the attached CA emissions form? Is that standard or did this actually have something to do with emissions? Not like VW/Audi, right...

 

It's a new standard. You can't get registration stickers without it now in the Peoples Republic of California.

This problem has occurred on a few of the new MDXes. It happens only on models with auto start/stop. It can be quite dangerous because one of the owners had their MDX shift into neutral on the highway. One can imagine the frustration and panic that occurs when this occurs at high speed.

 

Got mine today. Was surprised as I hadn't seen this notice mentioned.

With the last software update, it took a few weeks for the rough shifts to work themselves out afterwards. My car is shifting beautifully right now, so I am not looking forward to possibly upsetting things.

VIN is < 2000, and I also have an AWD, Advance model.

 

So last Friday I got a letter from Acura saying there is a fault in the Power control module/ECU code whatever, which could lead to the car failing an emissions test. So I took it in and had it done yesterday. Only affects 4 cylinder TLXs, and mine is very early (Canadian, Nov delivery). I see no sign of this on the internet. Just bizarre timing - the same day VW is exposed for manipulating the ECU code to pass, this is like the exact opposite. Very curious.

 

Got the notice today regarding TSB 15-034. I have a 2015 TLX SH-awd Advanced serial 5999 and it applies. Will take in tomorrow...BTW have had no issues otherwise. 3200 miles.

 

Got mine yesterday, service done today. Also got 15-040 done while they were updating software anyway. Too soon to know how the shifts will be, but mine were not so bad in the first place.

 

Is this different from TSB 15-034 which only affects V6 models?

I haven't received a recall yet. I have had my TLX for a little over a year and put 18k+ miles on it. The car shifts and drives great.

 

The recall notice does not say what models, but the description exactly matches 15-034.

 

My recall notice does not say what models it goes to, but the description (DCT P0657) exactly matches 15-034

 

Check your letters/notices. Does it say Important Safety Recall on it or does it say Product Update? What does it say exactly? Please post a picture of the letter/notice.

TSB 15-034 - Product Update: Vehicle Shifts into Neutral and MIL Comes On with DTC P0657 is for the V6 models with the 9-speed A/T and is currently a product update, not a recall.

TSB 15-024 - Product Update: PCM Software Does Not Meet OBDII Regulations is for the L4 models with the 8-speed DCT and is currently a product update, not a recall.

 

We agreed in posts 7 & 8 that this was not a recall. I have looked for some way to go back and change the title of this post but I have not found how to do that. I would like to take the word recall out of the title and instead say tsb 15-034. Anyone know how to do that?

 

Gary3N,

I have the same TLX as you with an ending vin of 005001. Mine must have been 3 cars ahead of yours on the assembly line, but I have not received a letter.

 

Update on the update--Updated

Well seems like my dealer did not do the TSB 15-034 product update correctly yesterday. Noticed today that the Engine Auto Idle Stop no longer engaged. (I am one who likes this feature, but maybe for the others this is the "solution"?)

Today they re-did the update and idle re-learn and Auto Idle Stop is back to normal.

 

The idle stop will come back. Mine did that too after my update

 

I had the same concerns as I thought my TLX SH-AWD ran pretty well Had the update done 15-034 and the idle relearn. Wow the car is a rocket firing off shifts smooth as silk. Going 80 mpg before I knew it. Guess my car was not as good as it could be. No problems so far

 

Well few problems have shown up. Auto idle stop has been inactivated and the car won't download my iPhone phone book now since the upgrade. Anyone else have problems like these after the update

 

I had the Idle Stop issue. Was caused by a flawed execution of the update. Take the car back and get them to do the PCM update again. That fixed my Idle Stop.

Don't have an iPhone, but that may well be related.

 

I have the same problem.
The car goes in tomorrow to fix the update.

 

So have been driving now a few weeks after the 15-034 update. All shifts quick and smooth and acceleration faster. Love how it drives now. Auto idle stop seems permanently disabled so I no longer have to turn it off everytime I get in the car. Thinking about leaving it as is Never used it anyway

 

Auto idle stop returned without redoing the update. Took three weeks weird

 

Could it be that the battery charge level was low, and has now returned to full capacity?

 

Battery was tested as part of the service done when the TSB 15 -034?update was done and was reported to be ok

 

It's been a couple of months since TSB 15-034 was applied . Idle auto stop works again and the transmission shifts flawlessly in all modes no hard shifts great acceleration and only slight surge when downshifting but only in sport+. Hopefully this is permanent

 

This is not an actual recall but MOST dealers are reaching out to customers and doing this software update. I guess they don't recall something that the lovely Government deems to not be a safety hazard. They missed the fact that should one be making a left with a small gap, nothing could happen if you lost acceleration by being in Neutral. Knucke-heads! T-boned, can you say that?

 

I had TSB 15-034 done on my car several days ago. On the way home the engine auto stop/start did not function. I stopped the car and the engine kept on running.

I called and talked to the service manager. He said there are many parameters needed for the auto stop/start to work correctly. One of these is battery voltage. Since the car was sitting in the shop with the battery being used and the engine not running he thought the battery might be low - and that was causing the issue.

I put a battery charger on overnight and the next day the auto stop/start feature worked correctly. I am not entirely convinced that low battery voltage was causing the issue but I thought I would toss this out as one possible thing to try if you have a similar problem. Without putting on a battery charger it could take a while for the battery to charge in normal driving.

I am still in the "relearn" phase so it is too early to tell if the shifting harshness was affected.

 

The issue with the auto stop/start not working after a "relearn" has been discussed elsewhere in the forum. The short of it is that the "relearn" failed. Here is a quote from my service report correcting this problem: "Caused by The Idle lean was unable to relearn it peramiters[sic] Work performed... update the PGM-FI Software OP#123317H"

Others have reported that the auto start/stop comes back with no intervention.

 

I just had this update performed at my must recent service a few weeks ago, and while my tranny was performing fine. Occasionally the 2-3 shift was a hard one. That's completely gone now, and I just realized that I never even pay attention to the shifts anymore while before that hard shift would remind me about the tranny.

Hesitation for downshifts on the highway was also greatly improved!
