Maybe it's a good engine but what is considered "normal" is weird. A
single noisy valve is something everyone can deal with after 100K miles
or so: but in a new car?? Also, if you start your car in the morning and
the belts squeal like some pulley has frozen up, It's just your
imagination because it won't do it at the dealer shop. Consumer Reports
rates toyotas as very reliable but their dealer are rated among the
worst. I guess a reliable car is not much use if the dealers
can't/won't do repairs.
Good luck folks.
