Any other high mileage 14,15, or 16’ Impala with the V6 ?

I was wondering if there is any more other high mileage impala’s out there and are there any problems to possibly look out for after 101k miles , I have an 16 LTZ with the V6 (100839 miles) . Haven’t had any problems besides battery going dead , key fob battery going dead, and recharging the A/C . I bought this car brand new in September 16’

For sure check your intake hose on the air box if you haven't already. Cant stress that enough on these newer impalas.

Make sure you don't beat the thing to death, your TCM will go sooner or later with the pesky fluid pressure switches breaking. Typically happens between 60-80 thousand miles with normal to abusive drives so you are overdue, with what I assume are strictly highway miles. Mine went on my 13 at 86, but I knew I'd get what I deserved spinning tires and such. What you should think about is that the car is double the age after 100,000 and worry about how you drive to not break things, how to get the best MPG, how to get more years out of the car, etc. A 2016 with 100,000 is no different then a 2012 with 100,000 if that makes sense.

intake hose supposedly is warranty item but i dont know if i have the receipt and can prove is under 100K when i did it.

i have 165K on and all passed inspection just yesterday

did front brakes at 100 and rear at 130. fronts measure 5 and rear measured 10.

i had a rear hub issue and that was expensive.

i did all shocks/struts but think i caused it by doing dukes of hazard jump so i cannot necessarily fault chevy.

trans went at 130K. 3800 for rebuilt GM with 100K warranty so that gets me 3 years.

my trip B odometer is 50K with 24.7 miles so considering how fast i drive i think thats excellent. i accidentally reset it before but wanted a longer interval

re: the TCM comment above. i'm assuming since i got new trans that i got new trans control module????

make sure u rotate your tires! i do that myself mostly unless is too cold out.

my battery died last year. makes me wonder if just should replace every 3 years regardless. got the best NAPA one cause AAA wanted 250 to replace in my lot.

before trans went bad i had trans fluid change at 100

if anyone could supply guidance on other things like brake fluid it would be good.

i did radiator drain/refill at 150K but other than the upper hose the other 2 seems like a PITA even with the correct tool kit i bought so i just keep the hoses in my trunk. man they make things tight. i cannot even see the lower clamp!

i use my winter mats so the interior still looks 90% new id say.

i keep wondering if i should start replacing things before they break..but maybe they wont..water pump etc.

166K on 2014 Blue Ray Metallic 2LTZ with 19s and nav. sadly new trans at 140K. Used to own 1995 DCM SS with only 260K!

Wikipedia states the same transmission the 6T70 is in both generations, in which I thought the thread starter was referring to the Limited rather than the newest body. Really how different can the two gens be, knowing GM they probably made everyone over pay for a body kit.

Also how did your trans act when you though it was bad, the TCM fluid switches often slams the shifting points down and up when they break acting like the gears are slipping. The same problem has been happening on the 6T7X since 2009 in the Acadia and also some 6L80 autos.

Brakes have atleast 60% left , they still feel good . I plan on waiting to do full tune up at 150k because I planned on doing at 100k but I was informed by the dealer to wait but I had them inspect the whole vehicle and everything came back okay so maybe they resolved the issue before the 16’ model year came about . Had the transmission fluid changed at 60k . I haven’t yet changed air filters . Average MPG is 27.1 . All highway miles

they checked the whole vehicle so I assume they checked that but I’ll double check !

the plugs are such a PITA. i paid for them to be done. what more is done at a tuneup anyway? i had them do the intake since it was off

On a 13 lfx? Plugs on these cars can be done by a diy'er easily in under an hour and the intake does NOT have to come off to change them. Next change I am sure I will be able to get them done in about 30 minutes.

Can't speak to the chassis on the 9th gens and not sure they share the same hub assemblies. They do share the same engine though. Had 157,513 on our 2012 when I changed the oil in it yesterday. For the first time ever it was a little low on oil at the oil change,lost a little more than half a quart. With 33 percent olm was just shy of 6000 miles since the last oil change. I read here about these motors being known for burning/using oil, will probably go to 5000 mile changes and be keeping a little closer eye on it.

No major mechanical issues(knock on wood).

While that certainly is a lot of miles for the age of the car it is by no means high in terms of how far you can go, there are several things I would address at the 100k mark mostly to do with fluid flushes such as:
Transmission fluid flush and filter replace (this is crucial, most car owners neglect this completely, it will cost you 3-400 but will greatly extend the life of your car's transmission).
Brake fluid flush (this needs to be properly done and not just the fluid taken out of the reservoir).
Coolant flush (careful don't mix the green with the orange).
Power steering fluid flush

I do believe yours has the 100k mile Iridium spark plugs which likely could use replacing about now as well.

I think that's it, I would have someone go over the suspension but usually the rubber parts won't start to really need replacing until the 200k mile mark and from what I have seen most American cars today go an easy 200k and I've seen quite a few hit the 300,000 mile marker. You might want to look into getting seat covers (especially the driver one unless you frequently carry passengers then those as well), as well as floor mats, these will greatly extend the life of your upholstery and carpet.

I have a 2014 Limited with now almost 92,000 on it. I put just over 500 miles a week on it running back and forth to work. Other than synthetic oil changes, two transmission fluid drain and fills, 2 cabin filters, 2 air filters, 2 front hub bearings, and turning the front brake rotors, the car has been easy on the wallet in terms of maintenance. In the next month or 2, around 100,000 miles, I am going to change the antifreeze, spark plugs, brake fluid and check the belt. Still on the factory brakes, tires were replaced not too long ago along with an alignment and still on the original struts and all suspension parts, save for the Addco sway bar and bushings and Moog rear end links I installed when I got it (took them off the 2002 Grand Prix I traded in for the Impala).

The car has been great, no issues whatsoever. For the mileage I run, it is a good car to do it with. I am fanatical with maintenance and receipts and documenting it. If you can buy one with proof of maintenance, it is a no brainer.
