Walser Toyota

We bought a used 2010 Toyota Sienna in March 2019. The van had "perfect maintenance records," one owner, reasonable miles and had "passed the Walser inspection with flying colors!" As soon as the snow melted we noticed a sound, three visits to the mechanic later they said they were shocked because they wouldn't expect it on a van like this, but that all that was left that could explain the noise was that it needed a transmission rebuild! When we had discussed buying the extra warranty at Walser our salesperson said (and I pretty much quote), "It's really up to you, with a van this age you could run into the automatic doors stopping working or other typical issues that an almost 10 year old van would have, but it's not like a toyota with this service record and milage is gonna need a new transmission or anything crazy like that!" We decided we'd owned toyotas for years and we'd assume the reasonable age related wear and tear costs and forgo the warranty. When we got the quote from the transmission place (at least $2500 for labor plus whatever parts) I called Walser's service department and our salesperson both. The service department said the only thing they could do was put in a Toyota rebuilt transmission for $5500, the salesperson said he'd text me the number for a transmission place he's heard good things about and wished me luck. I reached out via email to Walser and asked again what they would do to back their sale... I got an automated message and no follow up. When the transmission was done, our bill was $5000. Making our $13,000 used 2010 minivan into a $18,000 used minivan... just months after we'd purchased it from Walser. Shame on them for not taking any responsibility or wanting to do right. I will NEVER go back and will tell everyone I know never to trust this dealership. This gives used cars a bad name. So disappointing.
