The 25 vehicles with the most reports

Each row is one model year. The bar is its count of drops into neutral reports; the share is how much of that car's complaint file this problem takes up. Bigger sellers draw more reports, so read the share alongside the count. Red dots mark crashes and fires in these reports; amber marks a recall on the same system.

Where it dominates the complaint file

Model years with at least 25 reports, ranked by the share of all their complaints that describe drops into neutral. That takes most of the sales-volume effect out (small sellers still swing more).

What it is and what to do

About 1,400 complaints on this site describe it, with a median mileage of about 75,000. The 2016, 2014 and 2018 Ford F-150 and the 2014 Jeep Cherokee lead, and the F-150 model years 2014 to 2019 fill much of the list. Just over half use the word neutral, and about four in ten describe a downshift, often into first gear. About a third mention a warning light or message. About three in ten say turning the car off and on again, or stopping, brought it back. More than a third were told the dealer found nothing or did a software update. About one in twelve say they nearly got rear-ended.

NHTSA's files show real campaigns behind these reports.

  • Recall 16V-529 covers 2014 and 2015 Jeep Cherokees and the 2015 Chrysler 200 with the 9-speed transmission: insufficient crimps in the sensor cluster wiring could let it shift to neutral unexpectedly.
  • Recall 19V-447 covers 2014 Cherokees with the 3.2L engine: if a clutch sticks, the software may shift to neutral.
  • Recall 24V-444 covers 2014 F-150s that can downshift into first gear when the output speed sensor signal drops out, and 26V-237 covers 2015 to 2017 F-150s that can downshift into second gear on a lost range sensor signal. NHTSA's preliminary evaluation PE25-002 looked at unexpected downshifts on 2015 to 2017 F-150s with the 6R80 transmission and closed on January 30, 2026, and its file lists 26V-237.

Firestone lists gears that struggle to switch, a lit check engine light and gear changes that feel jarring among the signs of transmission trouble, and says low or contaminated fluid is a common cause. Its advice for a check engine light is to have a professional look at it.

Ask the shop to scan for stored transmission codes and to check your VIN against those campaigns. Say what speed you were at, which gear it dropped to, whether the rear wheels skidded, and whether a message showed first. A restart that clears the problem doesn't mean it's fixed.

If it happens in traffic, get to a safe spot before doing anything else. Recall repairs are free, and a defect reported during the warranty must be fixed even if the warranty runs out first, per the FTC.
