I own a 2015 Acura TLX V6 and every time I make a left or right turn, the car completely loses power and once I straighten out the wheel, it lurches forward and regains power.

 

This is the "normal" behavior of the ZF9... Read the transmission-related threads in the forum for additional context.

 

perhaps the battery cables are loose?

 

Battery connections are a great thought justnspace. OP: Is the car actually losing power? Or is it more like the ZF9 upshifts when turning (especially right) way too early resulting in engine lugging and sluggish acceleration through 2nd gear? If so, that's the normal stuff TSXV6Guy mentioned.

That right turn lag is a regular occurrence for me. You get used to it. The onramp hesitation happens less often - it's that two-second delay between pushing gas pedal and getting a throttle response. You get used to that too. Give your body time to build up an immunity to all of this stuff. You won't stop noticing when it happens. You just get less angry or surprised when it does happen.

 

But I only lose power when I take left and right turns. I'll check the battery connection when I get a chance. I just brought my car in to get a software update. A recall came in the mail. Something about a fuel pump. Hopefully that resolves it. So far so good.

 

unfortunately there is no magic update that will fix your issue. I've even had my transmission replaced in my 15 tlx and that same thing still happens. It sucks that this transmission has that flaw, but you really do get used to it. knowing when it's going to happen helps a lot. I personally use sport + when merging into traffic or onto the interstate and it seems to help quite a bit with the issue.

 

No it isn't, I'm on my 2nd TLX neither had this type of issue

 

I have a nice right turn I can make near my house that lets my TLX experience this loss of power. I recorded it once for the dealer - you can see the tachometer drop and then pick up. They replaced the tranny at 50K and that didn't make a difference.

This has happened to me turning left, turning right, and accelerating onto the thruway here in NY.

I'm pretty confident saying my car is a piece of shit. Would not buy again.

 

Call me naïve, but deep down, I hope Acura is still "working on" these TLXs. I feel like this should be a really simple fix: reprogram the ECU with new throttle mapping or the TCM with new shift points. Try either one. Try both. Try anything! But here we sit with 4-5 year old cars that STILL have the quirks they had when they left the lot.

I think Acura has abandoned this first gen TLX, basically said "it is what it is" and moved on to the next gen. The replacement tranny (thank God) fixed the really hard shifting, but is still a confused, lazy unit. It's sort of a shame because the TLX is great overall, but the tranny/shifting and rear diff/vibration combined detract from everything it does perfectly. None of this stuff is ever going to be fixed. I wouldn't go so far as calling it a POS - it's a mess, to be sure - but after a month of driving it, agree that I would not have bought it. I learned many lessons buying my TLX. Read forums. Magazines are biased, so base research on actual owners/drivers. Don't make up your mind about a car before going to the dealer and driving it. Test drive much longer. Negotiate repairs and replacements before buying.

 

My 2015 TLX SH-AWD Tech was on the first off the line, built in Sept 2014. I had one of the first transaxles approved for replacement. I also got pre-release TSB fixes for the vibration, and for electronics issues. It’s been just one thing after another with this supposed “luxury” car.

I agree that this car is a piece of sh*t. Only reason I still drive it is because I paid cash for it, ACR gave me a $6500 settlement in early 2016, and I don’t drive it all that much. Only have 37K miles after almost 4 years.

For me, I still enjoy driving the car, but would never, ever buy another Acura or even another Honda (and I’ve owned 3 other Hondas).

 

And never ever buy a new vehicle in a new model year. Wait at least a year.
