NHTSA Complaint #11480260 — 2021 DODGE CHARGER

The issue with the vehicle is inconsistent and delayed power delivery. On numerous occasions, when trying to accelerate quickly in low gears (1 through 3), the vehicle exhibits an obvious restriction and/or lack of thrust. The vehicle does accelerate (sometimes poorly with hesitation) and the RPM's climb, but the power is severely reduced until 4500 RPM, then the power comes on strong without any change in throttle position or gear. The issue can best be described as feeling like you are towing something heavy with a rope, and at 4500 rpm, the rope breaks and the resistance is lifted. I have had it to multiple dealers, I have reproduced it, but both ran full analysis and it is "performing as designed". Both me and the dealer contacted the manufacturer and was told if there are no diagnostic errors, it is fine. There is no code or message. I have found at least 10 other owners of various vehicle models from Chrysler with the same engine and transmission combo that have the same issue. The 5.7 Litre HEMI V8 and the ZF8HP70 8 speed automatic transmission. There is no way to know it is going to happen. One minute it accelerates normally, the next it doesn't. It does not pose imminent danger, but it has put me in a precarious position more than once when entering a highway or pulling out into traffic and not knowing how much acceleration power I am going to have. It reduces confidence in the vehicle because of the inconsistency. The issue did not start occurring until the vehicle reached approx. 2100 miles. I also owned a 2020 version of the car that did the same thing after approx. 4000 miles. I traded it in on the 2021 because I thought there was no way they all ran this way, but apparently they do.
