Toyota and Lexus are #1 in cases of sudden unintended acceleration and FORD is #2. The current unintended acceleration plaguing newer vehicles is the electronically-induced type. The engine throttle control systems depend on computer software to command them. Sometimes glitches occur...like in some of your other electronic devices...which can cause the command to be different than what you desire. The evidence of the glitch is often undetectable after the vehicle is restarted. Unfortunately, the EDR (black box) is not always accurate as shown by expert Dr. Antony Anderson in his analysis of a 2012 Toyota Highlander. The EDR results indicated the driver was not braking when she was doing so. The EDR results are inconsistent.
The key to avoiding a horrific crash during a SUA event is whether or not the vehicle has an effective fail-safe in the event a glitch occurs. If it does not, as in the case of the glitch-prone Toyota ETCS-i, then the vehicle may become a runaway with an ineffective means to stop it. Unfortunately, the safety standards aren't as strict in automobiles as they are in airplanes. Some manufacturers have more effective fail-safes than others. In the case of Toyota, an embedded software expert, Michael Barr (see Oklahoma Bookout vs. Toyota court case involving a 2005 Camry) found that an electronic glitch could induce a SUA event. Another expert, Dr. Henning Leidecker, found that a SUA event could also be triggered by "tin whisker" formation, particularly in 2002-2006 Toyota Camry vehicles.
SUA events have been DEADLY for vehicle occupants as well as pedestrians and people in storefronts, buildings, and even homes. The numbers of such crashes are ever-increasing with the advent of the very complex ELECTRONIC throttle control systems.
With the increase in such serious vehicle crashes, there is a concerted effort to show driver "pedal misapplication" or a "medical condition" or some other reason for the incident...anything other than a vehicle defect. Investigators aren't scrutinizing the buggy electronic throttle control software or other conditions that can elicit a terrifying sudden unintended acceleration incident. They usually just examine the *mechanical* causes which tend to be just red herrings in these cases. Investigators simply don't have the expertise to find such electronic glitches. In fact, the staff at the NHTSA, National Highway Traffic Safety Administration, do not have this very specialized training!
Think of it...the next step in electronically-controlled vehicles seems to be so-called "self-driving cars." Do YOU want to be in a such a vehicle when there is no evidence that strict safety standards, particularly in the throttle control system's software, have been adhered to? Will you just BLINDLY trust the automaker (criminally-investigated and nearly-prosecuted Toyota and soon-to-be GM and others?) to come through for you and your family's safety *on its own*?
