Two problems related to check engine light on have been reported for the 2013 Toyota Tundra. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2013 Toyota Tundra based on all problems reported for the 2013 Tundra.
On two different occasions I was driving my Tundra on the freeway at approx. 70 mph. My truck lost power and I almost caused accidents on both instances since I could not accelerate past 40 mph. I had to manage my way out of the freeway to a safe place. 2two diagnostics were performed and I received codes p0418, p1604, c1241, p2445, p2441. I was told by the Toyota dealership that there was a problem with a faulty secondary air injection system pump and other components related to the system and I was provided a repair cost of over $3,000 dollars. I was later informed, and I discovered through research, that Toyota had installed faulty/defective air pumps in thousands of Tundras 2013's like the one that I own. I reached out to corporate office but they stated that my VIN number somehow did not "qualify" as one of the affected pickups. My Tundra only has 60k miles and I use it to commute from and to work basically. I perform routine maintenance. There is obviously a problem with a defective secondary air pump system that Toyota refuses to fix. My truck is a liability on the road and this is my only means of transportation. It looses power and the check engine light activates. Toyota recalled thousands of vehicles like mine and fixed them after they acknowledged that they had placed faulty air pump systems. My truck is a potential possible cause for an accident since it unpredictably looses power on the freeway. I have not received a solution from headquarters/corporate office to repair my truck at no price since it is affected by their faulty pumps. They did offer $750 dollars towards the cost of parts, meaning that I have to come out with over $2000k out of pocket. I need Toyota to take responsibility and fix my truck.
Cranked truck and check engine light came on. Upon computer diagnostics, find out there is a problem with the emissions system - stuck air injection control valves. After visiting two shops and talking to two more I find out this is an extremely common problem. There are literally tens of thousands Tundra's, sequoia's, etc with the exact same problem. There has been no recall, but Toyota has set up customer support programs (csp's) to reimburse some of those affected by high repair bills $3,000 - $5,000. This was obviously a very poor design by Toyota that's been dumped on their customers. My vehicle is not covered by the csp.
