Recently purchased a used vehicle from this dealership that there is a major issue with the drive train including the cv axel and also an issue with the tires that are on the vehicle. One of the tires had gone flat so I took it to the local Les Schwab to have it inspected and was told that I could not repaired it and that they could not sell me and put on the one tire because the vehicle manufacturer size was not met and that it can cause a danger on my 2015 Audi Q5 premium plus. The tire size that was on the vehicle that was purchased is 255/35ZR19, the manufacturers size is 235/55R19 per the les Schwab it can damage the vehicle and decrease the performance of the function of the vehicle which also impacts the speedometer reading and also the mileage tracking adding additional strain on the vehicle as well as decreasing its value faster. The vehicle is an all-wheel drive car and have the incorrect size is a safety concern as well as increasing the amount of mile that are driven that are artificial, also messing with the speedometer reading to have to go 10 mile over the limit to make it go the correct speed, this makes the computer think the vehicle is driving more mile than it is. I have informed the dealer of the issues, and they have refused to help and state that there is nothing to be concerned about. This information was not disclosed to me when purchasing the vehicle.

Timing belt broke while traveling at 75 mph on the highway, and at 71,000 miles odometer How was your safety or the safety of others put at risk? Car was shaking and acting crazy on the interstate Has the problem been reproduced or confirmed by a dealer or independent service center?

Inspected by Audi of Louisville Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No they came on AFTER the car started shaking violently on the interstate I am still waiting on a second quote of getting this engine repaired from another certified repair center. I will attached what I paid for the diagnostics report. Per the manual on this car, you should CHANGE your timing belt at 100,000 K miles- Not have to replace your engine because it breaks prematurely at 70,000 miles. This is terrible for this quality of car and price!! I am furious!!
AFTER HAVING DONE THE EPA & CARB APPROVED EMISSIONS MODIFICATIONS 2014-2016 3.0L TDI (GENERATION 2 PC) EMISSION RECAL 23V4, THE CAR DEVELOPED A LURCH OR HESITATION BETWEEN 30 AND 40 MPH. THE SERVICE ADVISOR AT THE DEALER SAID THERE'S NOTHING CAN BE DONE. THIS IS A SAFETY CONCERN BECAUSE I'M AFRAID THE CAR WILL EVENTUALLY STOP IN THE MIDDLE OF THE ROAD, LOSE CONTROL OR CAUSE A CRASH.
