2007 Nissan Quest Minivan 3.5 SL 4dr Minivan (3.5L 6cyl 5A)
DO NOT BUY THIS CAR
 i have a 2007 Nissan Quest with 135K miles. Prior to hitting 100K the car engine wise was Ok, but I constantly needed brakes, and every single component of the interior was broken, the ridiculous placement of the cupholders on the rear seats, came off everytime someone got out of the car, every knob had fallen off, the windshield wipers were terrible, it was a mess, but since the engine was good, I carried on. When the car hit 100K all that changed, i needed motor mounts, timing chain is now deteriorating (thats what the dealer said) I can  no longer open the windows and when I went to dealer to see about fixing that, he said the part( a new switch) was $600!!!!! I kept hearing a knocking sound when i switched gears, and was told it was the need for motor mounts which could've also been causing the poor acceleration and revving of the RPM's while car went no where, so 1000$ later motor mounts were fixed, and car still makes knocking sound and still has acceleration problems, i had the transmission tested and and apparently thats shot now too, DEALER actually said its not worth fixing due to the timing chain issue??? its only 2007 and I was hoping to get to 200K and kept up on all the maintenance for that reason??????? I wil never buy a NISSAN again , and will  tell everyone i know about the poor quality .
