Audi Sees More Battery Recalls, Porsche Likewise Impacted

Audi’s all-electric e-tron subbrand continues suffering from battery issues, with the company recently issuing a recall for the GT sedan and its zestier RS variant. The issue is that the high-voltage batteries equipped to the models might short circuit, posing a fire risk to owners and whatever they’ve parked their EV next to. The recall report stipulates that Porsche warned Audi of the possibility of “thermal events” after realizing that some Taycan models were suffering from battery defects.


The two models are mechanically similar and have identical battery modules, so Audi and its supplier (LG Energy Solution Wrocław) were effectively obligated to look into the matter. The companies are now recommending that owners only charge the vehicles up to 80 percent capacity to help mitigate fire risks.


Recalls have been on the rise generally in recent years with system integration issues outpacing faulty parts. As the industry continues pivoting toward “software defined vehicles,” we’ve seen an uptick in recalls and complaints pertaining to electrical issues. However, there’s often a fair bit of overlap now that so many vehicle components have been turned into drive-by-wire units or have to be networked together.


This has also resulted in battery issues due to the fact that an electric vehicle's state of charge and how it regulates charging is handled by the computer. In the past, we’ve seen automakers tweak an EV’s code via over-the-air updates to expand its range or mitigate charging when there’s a problem. While the practice opens a gigantic can of worms in regard to who actually is in control of the second most expensive thing you’ve ever bought, it likewise showcases just how much damage some bad software can do to modern automobiles.


Porsche and Audi seem to be suffering from both mechanical and software defects and opted to split their recalls into two groups. The first group doesn’t have a solution, hence the company suggesting customers don’t fully charge their vehicles as a safety precaution. It is supposed to affect an extremely small number of the total involved in the recall. For Audi, that was said to be about 1 percent of 1,013 units.


The other issue only impacts a couple dozen vehicles. But it was said to require a battery replacement in all instances due to assumption that they’re suffering from a mechanical defect. These cars were singled out after the company parsed through the battery data that’s transmitted from the vehicle back to the manufacturer.


Our guess is that Volkswagen Group doesn’t want to install any more batteries than it absolutely has to and is just trying to limit repairs to a software update on as many Porsche and Audi models as possible. The symptoms of both recalls are so similar that it seems unlikely that they’re not closely related. If we were to speculate, there’s a chance that the vehicles getting new batteries are simply too large of a risk to try and solve with a software flash.


At any rate, the companies involved have said they will continue to study telematics data to determine whether or not batteries will need to be replaced. Customers that do have to have work done in relation to this will be able to bring it in for repairs free of charge under the recall.


All impacted models appear to stem from the 2022-2023 model years with the defect appearing quite similar to the e-tron SUV recall from December. In that recall, the EVs were likewise using batteries manufactured by LG Energy Solution and were similarly at risk of thermal runaway. Even the solution was exactly the same. Audi planned on implementing a software update that more closely monitored the battery system and would advise drivers not to charge their vehicle beyond 80 percent if something appeared off.


Sadly, the company didn’t think it would have a comprehensive solution in place until fall of 2024 — which does not bode well for the recently recalled Porsche Taycan and Audi e-tron GT.

  • Bkojote Allright, actual person who knows trucks here, the article gets it a bit wrong.First off, the Maverick is not at all comparable to a Tacoma just because they're both Hybrids. Or lemme be blunt, the butch-est non-hybrid Maverick Tremor is suitable for 2/10 difficulty trails, a Trailhunter is for about 5/10 or maybe 6/10, just about the upper end of any stock vehicle you're buying from the factory. Aside from a Sasquatch Bronco or Rubicon Jeep Wrangler you're looking at something you're towing back if you want more capability (or perhaps something you /wish/ you were towing back.)Now, where the real world difference should play out is on the trail, where a lot of low speed crawling usually saps efficiency, especially when loaded to the gills. Real world MPG from a 4Runner is about 12-13mpg, So if this loaded-with-overlander-catalog Trailhunter is still pulling in the 20's - or even 18-19, that's a massive improvement.
  • Lou_BC "That’s expensive for a midsize pickup" All of the "offroad" midsize trucks fall in that 65k USD range. The ZR2 is probably the cheapest ( without Bison option).
  • Lou_BC There are a few in my town. They come out on sunny days. I'd rather spend $29k on a square body Chevy
  • Lou_BC I had a 2010 Ford F150 and 2010 Toyota Sienna. The F150 went through 3 sets of brakes and Sienna 2 sets. Similar mileage and 10 year span.4 sets tires on F150. Truck needed a set of rear shocks and front axle seals. The solenoid in the T-case was replaced under warranty. I replaced a "blend door motor" on heater. Sienna needed a water pump and heater blower both on warranty. One TSB then recall on spare tire cable. Has a limp mode due to an engine sensor failure. At 11 years old I had to replace clutch pack in rear diff F150. My ZR2 diesel at 55,000 km. Needs new tires. Duratrac's worn and chewed up. Needed front end alignment (1st time ever on any truck I've owned).Rear brakes worn out. Left pads were to metal. Chevy rear brakes don't like offroad. Weird "inside out" dents in a few spots rear fenders. Typically GM can't really build an offroad truck issue. They won't warranty. Has fender-well liners. Tore off one rear shock protector. Was cheaper to order from GM warehouse through parts supplier than through Chevy dealer. Lots of squeaks and rattles. Infotainment has crashed a few times. Seat heater modual was on recall. One of those post sale retrofit.Local dealer is horrific. If my son can't service or repair it, I'll drive 120 km to the next town. 1st and last Chevy. Love the drivetrain and suspension. Fit and finish mediocre. Dealer sucks.
  • MaintenanceCosts You expect everything on Amazon and eBay to be fake, but it's a shame to see fake stuff on Summit Racing. Glad they pulled it.
