NHTSA Complaint #11530189 — 2017 INFINITI QX60

Driving West on I8 from AZ into San Diego my vehicle would lose all ability to accelerate and start decelerating on the upward climbs of the Crestwood Summit highway pass through the Cuyamaca Mountains. Not only it would continue to lose complete driving power and we had to pull over many time to turn the car off and let it sit for 10 minutes. It was not over heated and no lights were on with any indication of failure. During decents and on plateaus it resumed its completely normal functioning. I immediately brought it in to Oceanside CA Infiniti where they told me they don’t know what it wrong so they can’t fix it and I have to basically drive back to AZ through the mountains again and break down (it’s 115 degrees and almost 1.5 hours in both directions to any town) to figure out what was wrong. It’s incredibly dangerous and clearly not safe
