This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
2014 Chevrolet Tahoe police pursuit vehicle (ppv) issued new by highway patrol in 2Q14. Vehicle presented with near complete stalling at idle in park, as well as idle in drive with brake applied - where engine intermittently has trouble stabilizing rpms between 0.7 and 0.6, and the gauge needle moves back and forth, sometimes erratically. Also lack of power or lag, several seconds hesitation upon rapid and non-rapid acceleration (making even gauging and pulling directly out into highway speed traffic unsafe), uncontrolled idle surge when idle stalling regained throttle (resulting in forward lunging). Vehicle received a hot weather surge/sag engine calibration which only seemed to mitigate some severity of symptoms, but problems returned within days to weeks. Vehicle received at least another two separate engine calibrations with same results. With less than 15K miles, original symptoms remain and echo those of several other users in the same Agency (even in cooler weather). These are very similar to safety concerns raised in the 2013 model in complaints by municipalities in NHTSA complaints id# 10598212 06/19/14 and 10641010 10/14/14. Unpredictable lunging, lack of acceleration and hesitation are primary safety concerns for an emergency vehicle which must be predictable.
