We expect the 2025 Tundra will be less reliable than the average new car. This prediction is based on data from 2022, 2023 and 2024 models.
The Reliability score is based on our latest subscriber survey of 2003 Toyota Tundra owners. The owner comments describe problems respondents experienced with this vehicle.

"Battery tested low during service. Got a replacement at Costco & dropped it it. This is only the THIRD replacement battery in 20+ years and 223K miles. I've been getting about 7 years and 70K per battery (rated 3 year life)."
Anonymous A., CA (2003 Toyota Tundra SR5 4.7-L V8)"Poor experience with Certified Toyota Dealer service. My keyless FOB literally fell apart when I pulled it out of a jeans pocket. The plastic was 20 years old and had become brittle. I went to the dealer and they said they could sell me a replacement and pair it to the vehicle in about an hour. They estimated the cost to be $150-$200. I made an appointment and showed up coffee mug in hand to wait in their nice waiting area. After about two hours of waiting, I approached the service advisor. He said "issues" had turned up and he had his "best guy" on it. Cutting to the chase, after four hours they gave me my truck back, problem NOT resolved. Furthermore they said they "might" be able to fix it IF they could find a discontinued part somewhere in the US. Estimated cost would be "about a grand". They then wouldn't give me back my vehicle until I paid a "$100 for their efforts". They said they "lost money" on deal. I told them I lost money and a half day on NOT solving the issue. I explained that I brought it to a Certified Toyota Service dealer to avoid any situation like this. I've never been back to that local dealer - even after a change in ownership. I did end up disputing the charge with my credit card issuer. They immediately reversed the $100 charge. I'm still using my key to gain access to the truck cab. A bit inconvenient when my arms are full, but kinda retro to my earlier vehicles."
Anonymous A., CA (2003 Toyota Tundra SR5 4.7-L V8)"When the vehicle is parked for more than a week or two the residual battery charge is too low to start the vehicle. Trickel chargers do not maintain the charge in the battery for extended time. Vehicle has been tested for current "leaks" and none were found."
