Thank you so much!

My husband brought his truck to Petersen in good faith and specifically requested a complete…read moreinspection--including the flywheel--to determine the cause of starting issues. He was advised that the problem was the starter and was charged over $600 for its replacement, which we later learned is significantly higher than the typical cost at most shops. Unfortunately, the exact same issue reoccurred less than two weeks later. He then took the vehicle to another local shop, where they conducted a thorough diagnostic and identified the flywheel as the actual problem. They replaced both the flywheel and the previously installed starter from Petersen at a much more reasonable cost. I do not typically write negative reviews, but in this case, my husband was overcharged, and the initial request for a comprehensive inspection was not properly fulfilled, resulting in an inaccurate diagnosis.

Whether this is the truth or not, I have no way to confirm what others have said. That's why I came here. They seem a straightforward business and that's quite a bit better: one price, no funny business. You enter from the alley behind Main Street. Two of us arrived at the same time and they were quick to take care of both of us. My car is a 2012 I bought as a demonstrator in early 2013. There shouldn't be much of a problem. Even though it's a diesel-powered car, the rules have changed and the state requires smog testing. In any case, after they finished with the other person's truck, they put my car in the bay and checked it thoroughly. They found no problem, and created the form, as well as transmitting the results to the state. They were friendly and efficient.

We came in for a smog inspection on an older vehicle and ran into issues with communication and…read moreprofessionalism. We understand that smog checks on older vehicles are not always quick or painless, and that issues can come up. However, the interaction itself made the experience more frustrating than it needed to be. The gentleman we dealt with was short and somewhat flippant when explaining why the smog could not be completed due to an issue with the catalytic converter. A bit more time and willingness to explain the issue clearly would have gone a long way, rather than assuming the customer should already understand technical details. Because the issue was related to emissions, we asked about the type of repair work that might be needed to address the problem and potentially allow the vehicle to pass smog. We were prepared to move forward, but the response felt dismissive, as though our questions or business were not of interest. The price for the smog itself was reasonable, but the lack of clear communication and the overall tone left us with the impression that we were an inconvenience rather than customers looking for help. Ultimately, that confirmed we won't be back.

3 reasons why i wouldn't come here again 1 . No free…read moreretests ... never seen a shop not offer at-least discounted or free retests ( my first mistake ) 2 . Just like majority of consumers who drive vehicles , i have no access to a scanner to check if my " smog monitors " are set ... could have advised me and i woulda gone to drive and set monitors .. then came back for letting me know 3. Fails my vehicle under the " tampered " label because a connector didnt have a "module connected to it related to smog " ... when i asked if he knew what goes there he said " idk but its an emmission module .. i worked on a truck similar that had one " ... okk?? I called a dealership to look up what goes there to locate one and my truck does not come with anything there ... so being labeled tampered for something he wasnt fully sure about as a smog tech ... didnt sit right Overall.. he did my first vehicle there not too long ago and the process was fast and smooth Hence my score Thank you
