NHTSA Complaint #11698779 — 2018 JEEP WRANGLER

Unknown, but when I attempted to accelerate onto a highway, and the engine threw the check engine light along with the electric throttle light and the traction control system. The battery was still show 14.3volts, the oil pressure was in range and the temperature of the engine was normal. The vehicle wouldn't go faster than about 20-25mph with out shifting hard and or the RPMs rev high to shift. The mechanic said both batteries are shot and the electric mapping system maybe faulty.
