NHTSA Complaint #11537321 — 2010 TOYOTA CAMRY

1)the engine died upon stopping at the stop light,but was able to start again.the engine light & stability control light came on. the service dept replaced the battery and neutral switch was also replaced. 2) check engine light & stability control light came on again in the same situation.the technician suggested to remove the aftermarket alarm system for less than $1k(6hours of labor). I took the car to alarm installer to have it remove for a fraction of the dealer's price. this time i sought the help of BAR agent.Who had not shown at the service dept according to the Technician. i provided him all the receipt I had on hand. 3. took the car to another mechanic whose diagnosis was the same as the dealers.was advised to take it back to the dealer for they do not touch something that the dealer has started. back to the dealer, they replaced the shifter as it was contaminated by spilt coffee by the previous owner. 4) still, the same lights illuminated.this time car was in their shop from July 20th i was called two times to come and pick it up.but when I got there, not ready yet. today, I got there and was told that they could not do anything anymore. Either drive the car or towed somewhere else.my choice. how could i drive a car knowingly that it is not safe to do so. i was offered $7k( including all the monies I paid every time i drove off their lot.) to trade in for a new car in which i cannot afford in the first place. suggested to tow it back to the dealer where i bought it, Lexus of Sacramento. please advise.
