My 9.5yr old 60Ah Rex has done 117k and the battery is still excellent. Unfortunately it has a few other niggly faults which might end up costing me a bit to fix, but I really want to keep this for a few more years yet as a high mileage hero!

[@cristianseres1353]

I bought my 2014 60Ah i3 without Rex in 2016 and have driven about 97k kms. Rear disc pads and discs had to be replaced recently, but it also improved the range, apparently there was some brake drag. An AC expansion valve and a parcel shelf string have been the most expensive repairs so far. The i3 will be a future classic, ahead of one's time.

I’m shopping round for one next month any tips on what to look out for and what spec should I get ?

[@rusty911s2]

I'm sure Martin has done a film on this very subject if you search this channel. My own advice is that a high % of issues come from the Rex, so if you don't need to have a Rex version, don't get for the sake of it as they're more expensive, slightly heavier (obvs) and seem incredibly sensitive to faults. Front shock absorber gaiters seem super fragile. Generally though, unique in the market, fast, efficient and totally different to anything else. Feel very special to own!

[@richardpiper4828]

Martin has again demonstrated what a terrifically technically engineered and built car that the i3 is. When motor historians look back to the early 21st Century they will wonder at how brave BMW were to develop such an iconic car. Sadly much of the new materials used and the construction methods have not been carried forward into other subsequent BMW models but I suspect this is for reasons of cost and build speed rather than because the concept was wrong. I even think that in Apple CarPlay equipped models the infotainment tech is not very far behind the game and the iDrive controller is often quicker, more intuitive and safer than stabbing at a distracting touch screen. I intend to keep my Protonic Blue 94ah REx for the full remainder of my driving life - hopefully another 15 years - because I actually think that it will be the easiest and safest vehicle for an elderly person to drive on their weekly trip to the supermarket. That has over meant that my i3 is relegated to the back of the garage to avoid putting too many miles on the odometer.

[@trevorsmith8487]

I have a 2017 Rex with every option (took me ages to find) which I bought from BMW in 2020 with 20k miles on the clock. It's my second i3 having had an all electric 2017 as my last company car before I sold my business. When my elderly Dad was thinking of giving up driving I loaned him my i3 (for two years) and bought a XC40 Recharge Twin motor. Dad found the i3 super easy, and safe, to drive and it gave him another year or two of independence. Sadly he passed away in February and I now have the i3 back and should really sell it (I have a van and a V8 Mustang 😮 and half a dozen motorbikes as well as the XC ) but am so tempted to keep it as I absolutely love the i3, they're unlike any other car and are streets ahead of all other designs. I need to understand how best to store/use it so that it will still be viable for 10/20 years to come, a service with Martin and the team beckons 👍🏼

No issues, one set of 4 tyres plus about 20l of fuel; charged at home so my 80 mile commute cost about £1 compared to my previous company C200 at £10 a day.

Mine has 16.8 kapa which does stress me out if I’m honest.

[@clasqm]

The 400v traction battery on the i3 will outlive us all. The 12v battery is another story. My i3 has done 100 000 km and I'm about to install the FOURTH 12v battery. It is a tiny little unit (I've seen bigger batteries on motorbikes) and it has to run the AC not only to keep the driver comfortable but also to cool the traction battery.

[@johnbb99]

I'd say you've been unlucky. Your 100,000km is about 62,500 miles, and my 56,000 mile 2016 i3 is still happy on it's orginal 12V battery, and I know I'm not alone in having long-lived batteries. Have you been buying BMW replacements? Do they get coded so the car knows it is a new battery?

[@jamesvdv0]

The 12V battery is actually a motorbike battery. However, it does not run the AC as such. The AC compressor is powered from the traction battery HV system and the AC cabin fan and coolant pump(s) are powered from the 12V system only when the ignition is on with the DC-DC converter running, so also indirectly from the traction battery.

On icy roads - well I've driven better cars, but overall I would recommend it.

[@nigellucas560]

Exciting presentation. For all the times that I’ve driven to and from South Wales since 1992 this the most interesting . Great presentation.

[@plonkster]

I too wonder how to properly determine battery health. We own a 2015 BEV with the 22kWh battery. The car itself reports 13.2kWh left of what originally would have been 18.8kWh. That's 70%. If you read the codes/logs pulled with BimmerLink, there is one in there that suggests some internal degradation limit was tripped (from memory, I don't remember where I saw it). So the car thinks the battery is below 80%. The car still estimates between 90km and 110km on a charge, and the original range was around 130km, so that suggests 70% to 85%, but that's probably the least dependable number (the GOM is usually all over the place). While driving the vehicle, the range estimate will often improve or remain on the same value for long periods of time, again suggesting that the vehicle probably has the full 130km range left. But of course we have never run it completely empty (I've had it down to 6% once), and what I know of BMSes (I work in the solar industry), is that you don't know where the bottom is unless you discharge it to the point that a clear low voltage event happens on the weakest cell. There are apps for the phone. Since I have an Android phone, some of them don't work. "Electrified" doesn't work with the OBDLink Cx dongle. BimmerFlow is not yet available for Android (and will cost 20 Euro, I hear). And Mi3 is also iPhone only. So no easy software solutions that allows watching cell voltages (I believe they are NMC, so well known topic). Anyway, so for the moment, we enjoy the car and don't worry about it too much. But it would be nice to know if there is a way to actually test this properly. The only easy one I can think of, that involves no equipment, is running it completely flat, and then checking how much juice it absorbs on recharge... adding in a 5% fudge factor for the efficiency of the charger.

[@purple-porker-productions]

I don't know where you got that figure from but it doesn't sound right unless your battery is failing. I have a 2016 60ah and it's not noticeable lost any range. Thats after 103k too.

[@plonkster]

@@purple-porker-productions I got it from the hidden menu, as explained here: kzbin.info/www/bejne/pYbNnYl-o5qAfLM As this guy notes, this figure isn't necessarily the most accurate. The only real way to know is to let the dealer to a full discharge and recharge test, which is essentially taking the battery down to the very bottom and checking how much it holds. In the last few months, after I started regulating my lead foot a bit more, I have the consumption down to 14.4kWh/100km. The car regularly reports a range of about 100km. That suggests the battery has at least 14.4kWh left of the 18.8kWh, or about 77%.

I'm considering purchasing an early i3 but am wary after reading some scare stories in online forums of drive motor failures (and also aircon compressor failures) on early models after they've done >50k miles, apparently no longer an issue for models 2018 onward. Have you come across these issues often in the models you've dealt with over the years?

[@adobenumpty]

I love my i3. Next to my old Audi A2, which it replaced, it is the most fun and just as economical as the A2. Even a German motorhome on the wrong side of the road could not kill it. Scuffed Plastic panels replaced and it’s back on the road. The only issue I have had is having the windscreen replaced with Autoglass. They do not use the same BMW 70% transmission glass, and their inferior glass plays havoc with the TJA and auto cruise control. Probably because they did not recalibrate the sensor when they replaced it. I got that replaced with BMW glass and all is well.

The battery in the 94 Ah is rated for 4600 cycles or roughly 920000 kilometers if we assume you go on average 200 kilometers on a charge. The very low degradation that has been tested on high-mileage used examples supports this so far as well.

Wisely should join me, and others, in complaining to the national government (DVLA) and London (TfL) that the i3 Rex IS NOT A HYBRID, it can run as a BEV in all low emissions areas. A hybrid has a HYBRID DRIVETRAIN, the i3 doesn't.

This seems a great car concept as it has a range extender engine (heaven only knows why electric cars go "commando", it is a major safety problem).

Perhaps it is possible to add a bigger fuel tank? I would go for the Audi A2 currently in your showroom (and a good supply of replacement "death pipes" instead).

I hope this isn't the case for you but my 64,000 mile 2016 60ah Rex, owned from new and driven carefully, developed a misfire on cylinder 2. This ended up being a crankshaft failure which means an engine replacement. It's been in the dealership for 12 weeks now, should be back in a few weeks now the replacement engine has arrived from Germany. Luckily I kept paying the BMW extended warranty because I've been told a Rex Replacement by BMW is over £18,000. Point to consider if anyone buys a second hand i3 from a BMW dealer, the extended warranty only covers up to the value of the car for a claim. So if someone buys secondhand a Rex for say £11,000 the extended warranty won't cover a major repair like mine. Luckily as I've owned mine from new the limit is around £38,000 as I purchased new. Hopefully yours won't be a crankshaft failure but it's a known BMW i3 issue with a service sheet in their diagnostics which BMW Assist gave me a copy of.

Been thinking about a used i3, but you mentioned something that I wasn’t aware of - the REx can’t charge the battery up? I was under the impression that if I remained stationery and started the REx, I could charge it up - is that not correct then?

[@Renesis]

In theory no, but there is a trick with an emmisions mode, where you can open your hatch door, and start it in a special way with pedals where it can work for up to half an hour, but still, REX can only be in general turned on if the battery is below 75%, to keep the health ov the HV battery

[@DanSmithBK]

@@Renesis thanks for that - good to know!

I am driving a BMW i3 2014 with 224000km on the clock. It drives like a new car and its summer range is 145km -- which is close original range. 10 year old with 224000km on the clock. If this was an old fashioned combustion engine car it would have 1 leg in the scrapyard. However, these BMW i3 EV do not age as old tech cars. The durability of EV tech seems far superior to traditional fossil fuel burning mechanical machines.

[@SKraus-pb1ii]

interesting like always. Thanks!

The REX is what makes it unreliable bcuz there’s a million things can go wrong with a ICE engine.

[@saloserra5711]

I could think considering real life daily useability the battery degradation is not that much to complain in bmw i3 segment, what is getting worse over time and miles, is increasing energy consumption from the drivetrain itself because factory numbers claimed about 12.8kwh on 100km and the last numbers prove a real world consumption over 14,5 kwh+ so non climate on/ non heating >> this mater will be a bigger issue in the future price/kwh cost....

[@graemeglass7566]

How many ice cars are good after one Hundred Thousand Miles

[@Randomness662]

conclusion: once you hit 94k miles, trickle charge and discharge the battery all day every day for a month until the battery fails, then make a warranty claim for a brand new battery

[@tessasmith3426]

Why would you want to do that ? - as stated above, these HV batteries will likely outlive the rest of the car.

[@Randomness662]

@@tessasmith3426 this was obviously not a serious comment

[@anpn33]

I was quite surprised to discover that the petrol engine is made by Kymco and not BMW.

2020 i3s REx in US, loaded with leather, iDrive Pro nav, sunroof, HK audio, driving assist, PDC, adaptive lights. Currently my only car, used to be my city car, longer trips are done by a B9 Audi A5, but thats gone. Pretty good in the slow speeds, lacking a bit of top end power. Pretty useable in town, acceptable on motorway cruising at 70-75, not really the most stable car at higher speeds, nor the quietest. Not the most practical car since the boot is a bit small, enough for grocery getting, not that great for ikea hauls. For longer trips, the REx is great since I don't need to find a charger every 120 mi, just fire up the range hold and refuel it every 50-60 mi. But the driving experience is very boring, overall pretty good as a grocery getter with super low running cost.

[@samueltolentino322]

Boring driving experience? I think it's a blast. Got rid of my R8 as a daily driver for one. Was gonna upgrade to a Taycan Sport Turismo but I really didn't enjoy driving the Porsche, it was cramped and far less pleasant to be in than the i3s - worst of all the hatchback opening of the Taycan is way smaller than the i3's opening!

[@toyotaprius79]

If it had an engine (more than a 0.6l twin cylinder) that BMW was more than happy to make profits through regular parts and servicing, there wouldn't be such a scandalous neglect of servicing.

[@digginwithantony]

I have a 2018 42.2kwh fully-electric i3 @ 60k miles. I've only lost 8% of my battery. 😌

[@MichaelCornwall-zy8zc]

I have only recently bought my car and have experienced this twice whilst in pedal.

[@chrissmith2114]

Just get a Prius, laugh at high mileage, make great taxis and original models still running around happily.

[@designjunki]

Lovely little car, Until things start to go wrong then it becomes very very expensive and less lovely

[@v1nnyc]

What happens next year with road tax and the REX engine and having to pay road tax on BEV cars? Do you have to pay twice? For cars after 2017 i mean

[@TheWaseemMirza]

How about a 60ah BEV with 194000 miles? Yep i have that!

[@teklife]

weird to hear european guy always talking in mile per hour, wtf?

[@billturner6564]

I just don't see the point ??? Any car can get 400 miles on a tank and it's only 5 minutes to fill up and do another 400 miles 😅 who cares ? Have you achieved something remarkable? The only reason to run a i3 is tax and now you are going 2 pay 300£ a year like everything els so what's the point ? You cant get in to London for free so what's the point ? Ev cars are not better for the environment and it costs much much more to charge than buy petrol so what's the point ?

[@simon8864]

You shouldn't keep the battery between 10-90% Ideally 15-85% which is even better for battery longevity Also, fast charging is best avoided unless absolutely needed.

[@Go2Dragon]

When the only purpose of driving is to look at the range and %.

Hi Wisely - I bought an '18 i3 REX from a BMW dealer but then returned it a day later because I got scared off by this noise: kzbin.info/www/bejne/h5mmnHSvn5ZprLs Have you heard this noise before?

[@wiselyauto]

We have indeed... and we'd have picked up on it during sale preparation! Feel free to get in touch for a stocklist if you fancy giving i3 ownership another ago

[@MrDavidrosenberger]

@@wiselyauto Could you elaborate? What are some possible sources of the noise from best to worst case scenarios? How common is it? Should i3 buyers be listening and checking for the noise during a test drive?

[@wiselyauto]

The noise is caused by a failure within the e-transmission unit. It isn't common, and not something buyers should need to be checking or listening out for when purchasing an i3 from us.

[@MrDavidrosenberger]

@@wiselyauto As much I'd love to buy from wisely, I'm in Canada unfortunately. Would you be willing to share one more bit of your expert insight? Would this be fixed by replacing the entire transaxle? Or would the fix be to open the trans and replace just the bearings?

[@wiselyauto]

BMW generally only offer their transmissions as sealed units, with no official supply of internals. The situation for the i3 is much the same. The transmission would be replaced and, in the grand scheme of things, this is a fairly inexpensive component here in the UK at £695 + VAT.

[@boldford]

No thanks.

[@brocklanders6969]

EVs have poor resale and it negates any savings on gas.

[@geekosso]

it depends if you buy the car brand new or not... For sure second or third hand EVs are unexpensive to buy and to own. Especially i3.

[@geoffwalker7530]

Big problem with this is that it's made by BMW so total distrust of company

[@cookingonthego9422]

This extra range engine makes 0 sense. Why not just more bateries for range extender engine price. That will give extended range. Or just buy a hybrid. Is this fake name for hybrid? Bmw has too many engines just lying around?
