Parts Paralysis: A Shuttered Chip Plant Could Cost Up To 11 Million Cars Worldwide

A shortage of engine-related micro control units (MCUs) resulting from damage to Japan’s Renesas Electronics plant in Naka will curtail global auto production, says the market intelligence service ICSIS, citing a report by Germany’s Deutsche Bank. Renesas Electronics is the world’s biggest maker of automotive microcontrollers. It more and more emerges as a “key bottleneck in Japan’s parts shortage,” says Automotive News [sub]. One of its two auto-related factories damaged by this month’s earthquake won’t be operational until July.

Renesas supplies 18-20 percent of the world’s automotive MCU market. About 70 percent of the production is sold to Japanese automakers, the remaining 30 percent goes to US and European car companies. “The supply of these MCUs is not easily replaceable,” says ICSIS, “as boosting production at other sites could take as long as six to nine months.”

Renesas has only recently turned the lights back on at its Naka plant in the disaster zone. Engineers are now assessing damage to clean rooms and wafer fabrication lines.

Deutsche Bank estimates that 12 percent of the U.S. Big Three production is affected by the MCU disruption. In a worst-case scenario, global auto production of around 76m units last year could be reduced by 7.5 million to 11 million units, or 10-14 percent, say the bankers.

If Renesas is a bottleneck, power shortages are a huge barrier. As reported two days ago, car companies are thinking about rotating rationing. According to a report by Automotive News [sub], the electronic industries don’t want to be left behind and demand rotating production holidays between the automotive and electronics industries. This, or an overall reduction in electricity use in exchange for a minimal but steady supply, are seen as the likely options by the Japan Automobile Manufacturers Association, says Automotive News. In summer, Japan is estimated to be battling a power shortfall of 25 percent. Whatever option will be taken, power consumption and thereby production will be curtailed sharply for a long time.

    btw, wouldn't this be agood time for the chip supplier to explore taking-over or doing a jv before the business is moved anyway?

    @ John Horner My memory of these plants is from a few years ago, but I believe it's more complex than Bertel's report would indicate. These are not simple IC fabs, but assemblers/providers of complete controllers, or tested boards at least. Moving that capability would certainly be non-trivial. Vibration and temperature hardened devices like this aren't made like regular computing devices.

  • Duke Woolworth Weight 4800# as I recall.
  • Kwik_Shift_Pro4X '19 Nissan Frontier @78000 miles has been oil changes ( eng/ diffs/ tranny/ transfer). Still on original brakes and second set of tires.
  • ChristianWimmer I have a 2018 Mercedes A250 with almost 80,000 km on the clock and a vintage ‘89 Mercedes 500SL R129 with almost 300,000 km.The A250 has had zero issues but the yearly servicing costs are typically expensive from this brand - as expected. Basic yearly service costs around 400 Euros whereas a more comprehensive servicing with new brake pads, spark plugs plus TÜV etc. is in the 1000+ Euro region.The 500SL servicing costs were expensive when it was serviced at a Benz dealer, but they won’t touch this classic anymore. I have it serviced by a mechanic from another Benz dealership who also owns an R129 300SL-24 and he’ll do basic maintenance on it for a mere 150 Euros. I only drive the 500SL about 2000 km a year so running costs are low although the fuel costs are insane here. The 500SL has had two previous owners with full service history. It’s been a reliable car according to the records. The roof folding mechanism needs so adjusting and oiling from time to time but that’s normal.
  • Theflyersfan I wonder how many people recalled these after watching EuroCrash. There's someone one street over that has a similar yellow one of these, and you can tell he loves that car. It was just a tough sell - too expensive, way too heavy, zero passenger space, limited cargo bed, but for a chunk of the population, looked awesome. This was always meant to be a one and done car. Hopefully some are still running 20 years from now so we have a "remember when?" moment with them.
  • Lorenzo A friend bought one of these new. Six months later he traded it in for a Chrysler PT Cruiser. He already had a 1998 Corvette, so I thought he just wanted more passenger space. It turned out someone broke into the SSR and stole $1500 of tools, without even breaking the lock. He figured nobody breaks into a PT Cruiser, but he had a custom trunk lock installed.
