I come to Karl’s for any and all work needed on my vehicle; from service of oil changes, certified service, body shop when someone backed into me, trading cars. I’ve experienced most of the departments and have nothing but “glowing” reports. From representatives actually listening to me(being a widowed old lady) and actually hearing me when I felt my car had a need. Always very accommodating, knowledgeable, and experienced. I just traded vehicles and I can’t say enough positives about your staff. They made the process so effortless and positive. They worked with me until we found the vehicle that met my needs. Each individual I have worked with has been extremely customer friendly and that goes a long way with me!

When the cabin air filter was checked not all of the items in the glove box were put back inside and left on the floorboard. The owners manual and some cords weren’t put back, but what I really didn’t like was that there were some debris that was on the top of the filter fell into the glove box and was left there on top of the other contents. I didn’t appreciate the mess.

I made the appointment to have an engine vibration fixed. A Fault light was added to the needs as it showed up before the appointment. It took multiple reschedules and 2.5 weeks to fix the fault. I payed ~$2100 for the fault code fix and the car was returned to me with the same engine vibration and no mention of anything about fixing the engine vibration. The product itself is poor for needing this costly a fix for its age, but the service wasn't good on any front.

Everything was great as far as respect, finding a car to drive while mine was being worked on communication was great.. only problem I have is it still has that sleek or chirp when driving and if ya hit bumps, but when u have a little pressure on breaks it don’t make that sound. It’s something in the front but I really can’t afford to have it looked at and fixed again.

My truck came in on transport covered with mud. Had box cover and splash guards installed. I walked in the department unannounced to check on the progress and seen that the splash guards were installed right over the mud. I told them that this was unacceptable. I had them remove, clean and reinstall. Not a good experience for my first time doing business at this dealership.

Scheduled oil change + tire monitor system check (light on). Did not get oil change because it was never added to schedule. Service replaced two of the four sensors and the "Service Tire Monitor System" light came on following morning. Dave recommended I "check the tire pressure". No Dave, you just had my truck - why didn't YOU check the tire pressure. Truck shall return on Wednesday for more of the same...

I had previously asked to use the rewards points I had, but when I went to check out I wasn't aloud to use them. And then when I went to get back in my car oil was on my steering wheel and driver and passenger side doors. Not the best experience, I've had a Karl's!!!

I was disappointed with my experience at this dealership. Firstly, I paid for the oil change with a credit card, and the service advisor failed to provide me with a credit card receipt evidencing payment--this is required by law. I thought my copy of the invoice would show payment, which it did not; I did not know this until I got home when I looked at the invoice more closely. Secondly, the invoice referred me to a "Report Card" regarding the multipoint inspection; I did not receive a copy of the report. Thirdly, I took the truck in to have a noise in the dash diagnosed and addressed (i.e., warranty work); it has been doing it since I purchased truck new. The technician ran some tests but was unable to ascertain or replicate the issue. I was advised to bring it back and it leave overnight since the noise also appears when the truck is first started. Why wasn't I offered the option to leave the truck and given a loaner to take home? When I started the truck to leave the dealership, I heard the noise. Fourthly, I was at the dealership for 2 hours and was not given any updates.

They didn’t even know why I was coming in. My wife added the software upload that took over two hours. And didn’t solve the issue Plus because they didn’t know we have to go back when the needed parts arrive to fix the diesel gas cover Out time is money, can we charge for that? Of course not.

We were met quickly when we were looking for a truck and shown several trucks. Once we decided on one truck the salesman gave us a preliminary estimate of cost, including what incentives were available for us. We picked up the truck three days later and the financial officer when through everything with us. When we viewed the truck the running were not on the truck so we purchased some but then the salesman later called us to tell us the running boards were included. When going through the costs of everything we found that the running boards were listed as an additional item but that was quickly corrected. We are very pleased with the entire process and looking forward to driving the truck for many years.

We were there at 8 am and was told they couldn't do an oil change until almost noon, but when we got back there the gentlemen in there said they could have at that time. So for us that was a waste of time and GAS

After the hail repairs, my car outside and inside looks immaculate. Very happy with how it turned out. They addressed my concerns after pickup and was very courteous. I wish they offered a loaner as I was 30 miles away, limited with another vehicle to use and people to drive me. I have bought two new vehicles from this location, and plan to continue.

It was time to service my vehicle. It was so easy to make an appointment and they were able to fit me in on my requested date and time. Service was done quickly with care. I was reminded to come back in within 50/100 to have the wheels torque. Very professional, and patron oriented. My salesman, Leo has called me several times since purchasing my vehicle last fall to see if everything was going well. I appreciate that kind of customer care!

4 months for a transmission and 1 day after I got it back it started making noises and now they say they can't get it in for a week to look at it. They dont want to give me a loaner vehicle. The are always saying we dont have one and it takes 3 days to put it in the system. This is all factory warranty work.
