This complaint is regarding 3 issues since my vehicle purchase mid April of this year. The vehicles mileage at purchase was 7 miles and currently has approx. 6100 miles on odometer. The 3 issues are: #1) regularly while driving my vehicle at approx. 45-50 mph there is a steady humming noise coming from the engine compartment on the drivers side that last about 30-45 seconds. #2) also while driving my vehicle in traffic and coasting without pressing gas or brake going approx. 5-10mph the engine will shutter and cause the car to shake. The engine feels like its going to stall but I always press the gas petal so it continues driving without stalling since I'm always on the freeway when it occurs #3) involves the same or similar driving environment as issue #2. this issue occurs while coasting at various speeds unlike issue #2 where the cause feels like it could be the engine this is more like the transmission slipping into different gears mostly downshifting since the car suddenly jerks back as though you slammed on your brakes for a second and it regularly happens only while car is coasting at various speeds which I'm regularly doing since I drive down the cajon pass sitting in traffic every day, while coasting it happens almost every 90-120 seconds. On 7/21 I contacted my dealership and received a appointment for 7/22 since these issues could cause something very serious to happen to my wife or myself. Though I have not had my car looked at by my dealership yet, I still wanted to make this report to insure that other owners are aware of the issue I'm facing, and this hopefully gets investigated thoroughly (by a third party) before someone gets seriously injured in a accident.

My wife was driving the new Cruze through cleveland Ohio on May 19, 2015. We were using the navigation system because we were unfamiliar with the roads and area. While in heavy traffic the navigation system started to tell her to turn left and right in error because it was showing us about a hundred feet off the highway on small service roads. It was incorrectly trying to route us back to where we were already. This was confusing for her and caused her to slow down in traffic and become distracted causing a safety hazard as she had to ignore directions from the screen popping up and the speaker and try to figure out where to go. This problem has occured several times when using the navigation system. We took the car to GM dealership and they gave us a document from GM #pic6057A dated April 27, 2015. This says this problem is common with 2015 Buick encore and verano, 2015 Chevy camaro, Cruze, equinox, Malibu, ss and volt and finally the 2015 GMC terrain with the navi. It says the navi can be off by 20-50 meters. It finally says this is the normal operating characteristic of the vehicle and will not impact performance. I believe this is not normal and could cause an accident when drivers are in traffic and listening to the navi that is confused by reading the wrong location. This error/problem should not be considered normal operating condition and only shared with dealers for customers that complain. This should be shared with owners and the affected vehicles should be recalled for a fix before the problem causes an accident or injury.
