2009 Toyota Tundra Engine Problems

Your truck suddenly loses power and slows down to 30 mph on the freeway without warning. When this happens, your engine warning light, VSC light, and 4LO light all come on in the dashboard. A diagnostic scan shows error code P2442, which typically relates to the emissions system and can be expensive to repair.

Your truck unexpectedly slowed down on its own while driving at 35 mph, dropping to about 15 mph and entering a reduced-power "limp mode." A Toyota dealership diagnosed that your secondary air injection pump had failed. The repair wasn't completed because the pump's warranty had expired at 99,000 miles.

Your truck's engine suddenly died without warning while you were driving on the freeway, leaving you stranded and requiring a $100 tow home. A Toyota dealer diagnosed the issue as a faulty alternator, battery, and serpentine belt that had all failed, and repaired it for $761. The repair likely involved replacing the alternator, battery, and serpentine belt to restore proper electrical charging and engine operation.
