“This is an awd car purchased used 2 weeks prior to this incident. The car has only 11, 000 miles on it when this occurred. I was driving in bumper to bumper traffic in heavy snow conditions on an overpass bridge that merges onto a busy freeway. The vehicle's front wheels pulled the car to left 2-3 times at a speed of less than 5mph out of my lane but I was able to correct. …”
NHTSA complaint #10948676, filed 2017-01, 11,000 miles“On september 5th, I was driving my 2014 Infiniti Q50 and once it reached 2nd or 3rd gear, the transmission revved up and the car locked the tires up and threw us forward like it was slammed into a low gear. I had to tow the car home 400 miles and dropped it off at the Infiniti dealer on september 7th 2020. As of october 24th 2020, I still don't have my car back. I was informed by the parts manager at the dealership that there were over 700 valve body's on backorder. …”
NHTSA complaint #11366197, filed 2020-10, 97,000 miles“Driving car normally and car randomly put itself in 3rd gear and slammed down hard almost making me cause a crash and injury to me. Went to dealership they told me I need a new transmission due to valve body that they don’t sell by itself. This is the second time a replacement was done and it happened”
NHTSA complaint #11608240, filed 2024-08“I received a check engine light will driving which is now indicated as code P0720 and P0500. The car refused to shift past 3rd gear and began to sputter and would not allow me to go past 25mph disrupting the flow of traffic.”
NHTSA complaint #11673542, filed 2025-07“Transmission will not shift out of 3rd gear. I was driving down the freeway in 7th gear doing 75mph when all of sudden the transmission threw itself into 2nd gear then to 3rd. It felt like I was driving over a very large boulder and my transmission was being ripped out from under the car. Then my check engine light came on. So I had it towed home. I went for a test drive and the car will shift 1st, 2nd then 3rd but won’t go to 4th. It just stays in 3rd, it doesn’t slow down, it continues to rise in rpm and speed but won’t go out of 3rd gear. …”
