Right off the bat on day 1 was a failed door latch on the passenger front door. problematic front axle, after some fighting with Toyota they agreed to replace even though my truck wasn't covered under the TSB for it. At the same time I was complaining about poor shifts from 1-2. Could not recreate.
After the weather started to warm up the sunroof made terrible noises in the vent position and pinch protection would go off when trying to close from the fully open position. The noise while vented was fixed after I completely took the sunroof assembly apart, adjusted and lubricated the belt. Pinch protection continued to be a problem up until trade in requiring weekly calibrations in order for it to shut at all.
The lumbar in the drivers seat constantly crunches, toyota won't touch that unless I shell out over $500.
Repeated trips back to the dealer for the transmission shifting and referencing the appropriate TSB, tried multiple dealers with all coming back saying shifting and the outrageous whine it made was normal. Fluid has been flushed. Within the last few months the torque converter began to shudder and I began to have a very harsh shift into 5th. Dropped the trans pan at this point to change out the fluid and filter in which I found a large amount of gold shavings lodged in the filter. At that point I buttoned things up and started car shopping.
I dealt with owning a Saab for 4 years and had constant problems but I loved the car. I can't say much of the same for the 4Runner. I also bought the 4Runner because it was there and was priced well below book value. It wasn't exactly what I wanted and I can't 4wheel a truck as nice as it is. So in the end it was 50% of the issues and 50% of it just wasn't the truck for me.
