• 2023 Toyota Supra Transmission Control Module Recall (23V821)
  December 6, 2023 · 552 vehicles · Transmission

  The weld seam of the integrated transmission control unit's cover may not have been manufactured properly, which could allow automatic transmission oil to leak into the transmission control unit.

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 118, "Power-operated Window Systems."

  Risk: Unintentionally closing the windows or sunroof without the key present can increase the risk of injury to occupants inside the vehicle.

  Fix: Dealers will update the software for the Electronic Control Unit (ECU), free of charge.

Which Z4 parts are recalled most?

Which Z4 model years have the most recalls?

How do I check my Z4 for open recalls?

Enter your 17-character VIN at NHTSA’s recall lookup. The lookup lists every open safety recall on that specific vehicle, so you will see which of the 7 BMW Z4 campaigns above apply to you. You can also ask any authorized BMW dealer to run the VIN. The VIN is on your registration card, your insurance card, and a plate at the lower driver-side corner of the windshield. Brand-new recalls can take a few days to show up, so check again if you received a letter.

What are Z4 owners reporting?

Owner complaints filed with NHTSA since 2020, by model year. Complaints are unverified owner reports, but the components that come up most often show where owners are having trouble.

Excerpts from owner complaints (unverified):

There is a strong chemical smell when the AC is turned on and the system is loosing refrigerant. There is a common issue on these cars of premature evaporative core corrosion.

Can a recall make your Z4 a lemon in California?

A recall alone does not make a BMW Z4 a lemon. California's Song-Beverly Consumer Warranty Act looks at whether a warranty defect substantially impairs the vehicle's use, value or safety and was not fixed within a reasonable number of repair attempts (Civ. Code 1793.2(d)).

1 of the 7 recalls listed here follow an earlier campaign on the same component, which can mean a first fix did not work. 2 involve the engine, transmission or high-voltage battery, the kinds of repairs that often take several visits or weeks of downtime.

Within the first 18 months or 18,000 miles, California presumes the manufacturer had enough chances if the same defect was repaired two or more times when it is likely to cause death or serious injury, four or more times for any covered defect, or the vehicle was out of service more than 30 days in total (Civ. Code 1793.22(b)). Written notice to the manufacturer is required in some cases, and owners outside that window can still have a claim. An owner who prevails can recover reasonable attorney fees and costs from the manufacturer (Civ. Code 1794(d)). You pay nothing, win or lose. We are paid only if you win, and the manufacturer pays our fees, including in settlements. If a case is lost, our firm covers the costs.

What to keep: every repair order, the recall owner letters, your purchase or lease contract, and a log of dates, mileage and symptoms. Make sure every visit is written up, even when the dealer says it found nothing.
