Chrysler Restarts Second Shift At Toledo, Says It Has New Cherokee's Drivetrain Software Patched

Chrysler announced Thursday that it will restart the second shift of workers assembling the all-new 2014 Jeep Cherokee at the Toledo Assembly Complex next Monday after a week of downtime spent upgrading the software for the SUV’s powertrain. Chrysler had idled the 500 workers, it said, because it had built a sufficient number of vehicles to launch and that it didn’t want to overwhelm delivery logistics, but it was clear from the fact that none of the built Cherokees were being shipped and that some of the idled workers were conducting lengthy test drives that quality control was a factor in the shutdown. Chrysler software and drivetrain engineers have been working on patches to the engine and transmission mapping software and the company says that it has made progress on the upgrade.

“As we continue to refine the vehicle’s powertrain software, we are implementing a plan that will allow us to make the required updates more quickly than anticipated, thereby making additional layoffs unnecessary at this time,” Chrysler spokeswoman Jodi Tinson said in a statement.

Chrysler has been holding back over 12,000 finished Cherokees before shipping them to dealers. That’s more than $300 million worth of Jeeps at retail prices.

Automotive News had reported that the software at issue regulates how the ZF designed and Chrysler built nine-speed automatic transmission interacts with the Cherokee’s innovative free-wheeling driveshaft and rear differential which is supposed to save fuel. Chrysler confirmed the issue in its statement on Thursday.

“This is the world’s first application of a highly technical nine-speed transmission; on top of that, it is being mated to two new engines and three complex 4×4 systems. As our senior management has stated many times before, we will only introduce a vehicle to consumers when we are completely satisfied,” the statement said.

The engines are Chrysler designs, the transmission was licensed from ZF and the trick disconnecting driveshaft is made by American Axle, and Chrysler had to develop software to integrate the components and control shifting patterns and four-wheel drive implementation for each of the drivetrain combinations.

    I don`t understand why they would stop producing the trucks in the first place. If it is a software problem, would you not just reflash them when you discover the fix?

      @Kinosh Well, they DID say they have 12,000 of 'em waiting for upgrades. If it weren't football season, a single stadium lot should hold them all. OTOH, the traditional storage is dealer lots, with dealers selling them and then scheduling the upgrades in a recall and having dealers' grease monkeys do the upgrades. The emphasis on PR is killing tradition!

    Ahhh... makes one pine for the days of yearly tune-ups. Re-gapping plugs, adjusting dwell, etc. NO WAY! I love computerized cars, for they have never been more reliable and economical. Besides, I don't work on them anymore, and I'm happy about that! I just keep them cleaned and well-maintained. This gives me confidence in Chrysler I haven't had since Iacocca's reign. Seems they are trying to do it right. It's one thing to function in a lab under controlled conditions, but beta-testing in the real world is a different animal. I wish them the best with this launch!

      I'm with you, Zackman. No more busted knuckles. Besides, I can't even find the engine anymore, there's just this big plastic thing in the engine bay.

  • Lou_BC Hard pass
  • TheEndlessEnigma These cars were bought and hooned. This is a bomb waiting to go off in an owner's driveway.
  • Kwik_Shift_Pro4X Thankfully I don't have to deal with GDI issues in my Frontier. These cleaners should do well for me if I win.
  • Theflyersfan Serious answer time...Honda used to stand for excellence in auto engineering. Their first main claim to fame was the CVCC (we don't need a catalytic converter!) engine and it sent from there. Their suspensions, their VTEC engines, slick manual transmissions, even a stowing minivan seat, all theirs. But I think they've been coasting a bit lately. Yes, the Civic Type-R has a powerful small engine, but the Honda of old would have found a way to get more revs out of it and make it feel like an i-VTEC engine of old instead of any old turbo engine that can be found in a multitude of performance small cars. Their 1.5L turbo-4...well...have they ever figured out the oil dilution problems? Very un-Honda-like. Paint issues that still linger. Cheaper feeling interior trim. All things that fly in the face of what Honda once was. The only thing that they seem to have kept have been the sales staff that treat you with utter contempt for daring to walk into their inner sanctum and wanting a deal on something that isn't a bare-bones CR-V. So Honda, beat the rest of your Japanese and Korean rivals, and plug-in hybridize everything. If you want a relatively (in an engineering way) easy way to get ahead of the curve, raise the CAFE score, and have a major point to advertise, and be able to sell to those who can't plug in easily, sell them on something that will get, for example, 35% better mileage, plug in when you get a chance, and drives like a Honda. Bring back some of the engineering skills that Honda once stood for. And then start introducing a portfolio of EVs once people are more comfortable with the idea of plugging in. People seeing that they can easily use an EV for their daily errands with the gas engine never starting will eventually sell them on a future EV because that range anxiety will be lessened. The all EV leap is still a bridge too far, especially as recent sales numbers have shown. Baby steps. That's how you win people over.
  • Theflyersfan If this saves (or delays) an expensive carbon brushing off of the valves down the road, I'll take a case. I understand that can be a very expensive bit of scheduled maintenance.
