Example complaints

“Crankshaft angle sensor and camshaft position sensor both failed causing vehicle to stall at low RPM's (engine dies loosing brakes and steering). Infinity recall #r3021 has this problem yet my vehicle not included in this recall for some reason. Called infinity and they will not help me. What are my options? My cost is $621.86 repairs and diagnosis.”
NHTSA complaint #11296694, filed 2020-01, 135,500 miles“'tamara recall' my radio and complete column to adjust AC went out. There was a recal for my same year and model vehicle, but Infiniti is saying my VIN isn't covered. I took the steps to have the recall my fixed by a licensed mechanic and still nothing works. It is a safety hazard as I have a young child and the car only blows heat. In ca it it still very hot right now and cannot afford another vehicle.”
NHTSA complaint #11144920, filed 2018-11, 138,225 miles“While your driving you lose control of heating controls. It was raining and I had to defrost windows. Well it started heating the floor and I could not control where to direct heat. And note the radio doesn't work when it occurs as well.”
NHTSA complaint #11302194, filed 2020-01, 127,000 miles“I got my car in april 2013 not a year yet. I was at work when they said the light started to blink and then the alarm started to go off when the security came by around it was smoking and on fire it was coming from the hood. The police and fire station said they think it was a electric problems. I really don't know what I should do now.”
NHTSA complaint #10559996, filed 2014-01, 218,000 miles“Stereo doesn't work all of a sudden...then the AC turns on high level at 60 degrees. ? It doesn't turn off. My concern is that in winter when the front and rear windows are fogged up I cant heat them up to clear them which is a safety hazard..I don't understand why there's a recall on the sedan for the exact problem, but not the coupe.. Thanks”
