Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While turning across traffic from e 2nd ave onto josephine st. The accelerator pedal was depressed to the just above the floor and no discernable acceleration response was noticeable for a second or two. When there was an acceleration response it was an explosive, 'off to the races' one. …”
NHTSA complaint #10098104, filed 2004-11, 8,541 miles“While merging from highway 141 onto I-70 the accelerator pedal was depressed to accelerate from highway speed to merge into interstate traffic and no noticeable acceleration was apparent. The extremely concerning about this incident was that this merge was being executed between two 18-wheelers. While there was ample space to merge if the vehicle had responded without hesitation to accelerator pedal inputs, the experienced hesitation made the merge dicey.”
NHTSA complaint #10098103, filed 2004-11, 6,017 miles“While pulling out from a parking lot into major city street the vehicle hesitated to respond to accelerator input with approaching traffic. The vehicle moved off from a stop and into the closest lane fine but would not accelerate as more accelerator pedal was applied. There was noticeable delay/hesitation, as traffic bore down on me, before the cayenne decided to accelerate. Contacted dealer who noted that there was an unofficial fix that may address the issue.”
NHTSA complaint #10098089, filed 2004-11, 4,559 miles“Customer campaign notice received regarding main wiring harness routing. As well as problems with engine not responding to accelerator pedal. The vehicle's engine unexpectedly does not respond to input on the accelerator peal. This problem has occurred so many times that the consumer decided to put the vehicle in storage and no longer drive the vehicle. The consumer has complained to the dealer several times to no avail. The dealer insist that this is a characteristic of the vehicle.”
