Are Malaysian sold Supra cars affected by this recall?
This latest recall involves a surprisingly long list of BMW models made between 2019 and 2021, in addition to the Z4-based Toyota Supra too.
Yes, the RM570K Toyota Supra is actually a rebadged BMW Z4 sports car and it is technical collaboration between BMW and Toyota and this is not their only partnership vehicle.
The Toyota Supra uses a 3-litre turbocharged in-line 6-cylinder engine that produces 340 PS of power and peak torque of 500 Nm, a rear wheel drive layout, a sport-tuned 8-speed automatic transmission, 0-100km/h in just 4.3 seconds, perfect proven 50:50 weight distribution, Adaptive Variable Suspension and Electronically Controlled Limited Slip Differential (LSD), light 19-inch forged alloy rims, a Heads-Up Display, electrically-adjustable sports seats with power lumbar support; electrochromatic rearview mirror; and a 12-speaker JBL audio system. Quite a bit of equipment for a sports car.
That means you get performance without sacrificing luxury and ameneties.
Now according to BMW, the loss in braking assistance stems from the engine management software having the potential to cause a brief reverse rotation of the crankshaft in certain use case scenarios, which thus can cause damage to the oil pump that supplies the vacuum needed for the brake boost.
These certain use cases include pressing the engine start button twice in rapid succession, or by depressing the brake pedal very briefly while pressing the same button.
Thus far, a total of 29 warranty claims and four field reports relating to the issue have been identified by the German automaker. BMW however reassures owners that of affected vehicles would still retain all of its mechanical braking capability, and its investigations reveal that this fault only manifests itself after two or three full brake applications or approximately six partial brake applications.
As for the fix meanwhile, a complimentary software update is apparently all that is needed to remedy this particular fault.
BMW has also stated that it will be honouring the replacements of vacuum pumps on these affected vehicles for free, if any damage has been caused by this defect that is.
Owners of affected vehicles can expect to receive an official notification of this recall from BMW (or Toyota) starting from the 1st of October, with customers also able to check if their particular car is affected via the official recall page linked here. It is worth reiterating though that this recall is currently limited to North American-spec cars for now, with no word yet on whether this fault has plagued the cars sold in other international regions.
