NHTSA Complaint #11574971 — 2019 VOLKSWAGEN TIGUAN

I have a 2019 VW Tiguan with 2.0 liter turbo 4 cylinder and auto trans. I am experiencing frequent delayed acceleration from standing start in duration of 2 - 6 seconds. This BW is equipped with Drive By Wire technology which means an electrical wire with a solenoid at each ends sends a signal to motor to rev up. If that signal is not perfect the car suffers from a delay in acceleration from stopped position. I have reported this twice to NHTSA since Aug 2019 when car was newly purchased. Within first week I experienced a “delayed acceleration” from stop and under 1800-2000 rpm’s and under 25mph so this is NOT turbo lag as service manager first suggested. This always occurs from a dead stop pulling into traffic whether left, right or straight away driving. The delay occurs about half the time 5 out of 10. Fortunately for me the six second delay event occurred in church parking lot. During these episodes the engine remains at idle with the accel pedal fully depressed to floor, and at end of the event motor races and car takes off. To repeat there is NOT a mechanical linkage for accel pedal to motor, with “Drive By Wire” technology. There are literally thousand of reports online about these failures and a cottage industry has sprung up to decrease these “delays” (Roar Pedal etc) but they are ineffective. I believe this “drive by wire technology “ is a means that an auto mfg attempts to meet EPA city CAFE fuel requirements. I have requested VE replace one or both solenoids but they refuse until they can replicate the issue and BE corporate isn’t listening and a new 2023 Tiguan I test drive for comparison suffered same issue but less frequent in short 30 minute drive. It is up to you to investigate and require auto manufacturers to correct this major problem in public confidence in auto mfgs and regulatory organizations tasked with protecting the public.
